The agreements that defined associated practices to the CDM (Clean Development Mechanism) include energy efficiency in end users as a possible candidate to CDM eligibility. Worldwide, the experience of using 'carbon credits' resulted from reduced emissions in end users, as consequence of increased energy efficiency in processes, is limited. The paper presents preliminary conclusions of case studies developed by GERBI, evaluating the emissions reduction potential achieved by energy efficiency improvements in industrial processes, as well as financial impacts due to emissions reduction certificates traded. The paper considers a simplified methodology for feasibility analysis, but with necessary information to demonstrate how CDM and Energy Efficiency combination can support the decision for project implementation.

Guidebook to financing CDM projects

Energy Technology Data Exchange (ETDEWEB)

Kamel, S.

2007-07-01

One of the challenges facing Clean Development Mechanism (CDM) projects today is their limited ability to secure financing for the underlying greenhouse gas emission reduction activities, particularly in the least developed countries. Among the key reasons for this is the fact that most financial intermediaries in the CDM host countries have limited or no knowledge of the CDM Modalities and Procedures. Moreover, approaches, tools and skills for CDM project appraisal are lacking or are asymmetrical to the skills in comparable institutions in developed countries. Consequently, developing country financial institutions are unable to properly evaluate the risks and rewards associated with investing or lending to developers undertaking CDM projects, and therefore have, by-and-large, refrained from financing these projects. In addition, some potential project proponents lack experience in structuring arrangements for financing a project. This Guidebook - commissioned by the UNEP Risoe Centre as part of the activities of the Capacity Development for CDM (CD4CDM) project (http://www.cd4cdm.org) - addresses these barriers by providing information aimed at both developing country financial institutions and at CDM project proponents. It should be noted that while the Guidebook was developed particularly with the CDM in mind, most sections will also be relevant for Joint Implementation (JI) project activities. For more detailed information on JI modalities and procedures please consult: http://ji.unfccc.int The purpose of this Guidebook is two-fold: 1) To guide project developers on obtaining financing for the implementation of activities eligible under the CDM; and 2) To demonstrate to developing country financial institutions typical approaches and methods for appraising the viability of CDM projects and for optimally integrating carbon revenue into overall project financing. The target audiences for the Guidebook are therefore, primarily: 1) CDM project proponents in

On the contribution of labelled Certified Emission Reductions to sustainable development: A multi-criteria evaluation of CDM projects

International Nuclear Information System (INIS)

Nussbaumer, Patrick

2009-01-01

The Clean Development Mechanism (CDM) has a twofold objective, to offset greenhouse gas emissions and to contribute to sustainable development in the host country. The contribution to the latter objective seems marginal in most CDM activities. Also, CDM activities are unevenly spread among developing countries. In response to these concerns, initiatives with the objective of promoting CDM projects with broad local sustainable development dividends have been launched, such as the Gold Standard and the Community Development Carbon Fund. The Gold Standard label rewards best-practice CDM projects while the Community Development Carbon Fund focuses on promoting CDM activities in underprivileged communities. Using a multi-criteria method, the potential contribution to local sustainable development of those CDM projects with particular attributes is compared with ordinary ones. This evaluation suggests that labelled CDM activities tend to slightly outperform comparable projects, although not unequivocally

Wind power projects in the CDM: Methodologies and tools for baselines, carbon financing and substainability analysis[CDM=Clean Development Mechanism

The report is intended to be a guidance document for project developers, investors, lenders, and CDM host countries involved in wind power projects in the CDM. The report explores in particular those issues that are important in CDM project assessment and development - that is, baseline development, carbon financing, and environmental sustainability. It does not deal in detail with those issues that are routinely covered in a standard wind power project assessment. The report tests, compares, and recommends methodologies for and approaches to baseline development. To present the application and implications of the various methodologies and approaches in a concrete context, Africa's largest wind farm-namely the 60 MW wind farm located in Zafarana, Egypt- is examined as a hypothetical CDM wind power project The report shows that for the present case example there is a difference of about 25% between the lowest (0.5496 tCO2/MWh) and the highest emission rate (0.6868 tCO{sub 2}/MWh) estimated in accordance with these three standardized approaches to baseline development according to the Marrakesh Accord. This difference in emission factors comes about partly as a result of including hydroelectric power in the baseline scenario. Hydroelectric resources constitute around 21% of the generation capacity in Egypt, and, if excluding hydropower, the difference between the lowest and the highest baseline is reduced to 18%. Furthermore, since the two variations of the 'historical' baseline option examined result in the highest and the lowest baselines, by disregarding this baseline option altogether the difference between the lowest and the highest is reduced to 16%. The ES3-model, which the Systems Analysis Department at Risoe National Laboratory has developed, makes it possible for this report to explore the project-specific approach to baseline development in some detail. Based on quite disaggregated data on the Egyptian electricity system, including the wind

Understanding the CDM's contribution to technology transfer

Developing countries are increasingly contributing to global greenhouse gas emissions and, consequently, climate change as a result of their rapid economic growth. In order to reduce their impact, the private sector needs to be engaged in the transfer of low-carbon technology to those countries. The Clean Development Mechanism (CDM) is currently the only market mechanism aimed at triggering changes in the pattern of emissions-intensive activities in developing countries and is likely to play a role in future negotiations. In this paper, we analyse how the CDM contributes to technology transfer. We first develop a framework from the literature that delineates the main factors which characterise technology transfer. Second, we apply this framework to the CDM by assessing existing empirical studies and drawing on additional expert interviews. We find that the CDM does contribute to technology transfer by lowering several technology-transfer barriers and by raising the transfer quality. On the basis of this analysis, we give preliminary policy recommendations

The Kyoto Protocol's clean development mechanism (CDM) was established in 1997 with the dual purposes of assisting non-Annex I Parties in achieving sustainable development and assisting Annex I Parties in achieving compliance with their quantified greenhouse gas (GHG) emission commitments. This paper looks at the development of the CDM portfolio as well as achievements of the CDM to date in the context of wider private and public flows of investment into developing countries. These achievements include the development of 325 (by May 2005) proposed CDM projects which are together expected to generate more than 79 Mt CO 2 -eq credits/year during 2008-2012, increasing awareness of climate change mitigation options among possible investors and others that may facilitate transactions (i.e. governments), and the strengthening of climate-relevant institutions within countries. The paper also draws lessons from this experience to date, and outlines what changes may be needed to transform the CDM concept to a broader scale after the end of the first commitment period in 2012

The governance of clean energy in India: The clean development mechanism (CDM) and domestic energy politics

International Nuclear Information System (INIS)

Phillips, Jon; Newell, Peter

2013-01-01

This paper explores the ways in which clean energy is being governed in India. It does so in order to improve our understanding of the potential and limitations of carbon finance in supporting lower carbon energy transitions, and to strengthen our appreciation of the role of politics in enabling or frustrating such endeavors. In particular we emphasize the importance of politics and the nature of India's political economy in understanding the development of energy sources and technologies defined as ‘clean’ both by the United Nations Clean Development Mechanism (CDM) and leading international actors. By considering the broad range of institutions that exert formal and informal political influence over how the benefits and costs of the CDM are distributed, the paper highlights shortcomings in the narrow way in which CDM governance has been conceptualized to date. This approach goes beyond analysis of technocratic aspects of governance – often reduced to a set of institutional design issues – in order to appreciate the political nature of the trade-offs that characterize debates about India's energy future and the relations of power which will determine how, and on whose terms, they are resolved. - Highlights: • Clean energy governance in practice is shaped by political power and influence. • Governance of clean energy requires strong institutions from local to global levels. • Un-governed areas of energy policy are often as revealing of the exercise of power as areas where there explicit policy is in place. • Climate and carbon finance interventions need to better understand the landscape of political power which characterises India’s energy sector

Can CDM bring technology transfer to China?-An empirical study of technology transfer in China's CDM projects

China has undertaken the greatest number of projects and reported the largest emission reductions on the global clean development mechanism (CDM) market. As technology transfer (TT) was designed to play a key role for Annex II countries in achieving greenhouse gas emission reductions, this study examines various factors that have affected CDM and TT in China. The proportion of total income derived from the certified emissions reductions (CER) plays a key role in the project owners' decision to adopt foreign technology. Incompatibility of CDM procedures with Chinese domestic procedures, technology diffusion (TD) effects, Chinese government policy and the role of carbon traders and CDM project consultants all contribute to the different degrees and forms of TT. International carbon traders and CDM consultants could play a larger role in TT in China's CDM projects as investors and brokers in the future.

The Clean Development Mechanism (CDM) is a market-based tool introduced under the Kyoto Protocol to assist developing countries achieve their sustainable development objectives and at the same time provide opportunities for developed countries to meet their greenhouse gas targets cost-effectively. Projects based on renewable sources are eligible under the CDM. Such projects are also in line with the development of the fifth fuel option in Malaysia. The paper assesses the potential of CDM in renewable energy projects in particular the grid-connected biomass power projects under the Small Renewable Energy Power (SREP) Programme. The criteria (both national and international) that have to be met for the renewable energy projects to obtain approval as a CDM projects is outlined. The additional CDM activities are elaborated. The methodology for the determination of reduction in carbon dioxide emissions is provided. The paper further investigates the impact of CDM in the promotion of renewable energy projects in Malaysia

Project developers in South Africa are puzzled with the long process of evaluating and registering their CDM projects. In addition to other obstacles, we find that South African big businesses are rather reluctant to engage in any new business activities such as CDM projects and municipalities often lack the necessary flexibility. This offers opportunities for small-scale project developers who spot the opportunities and find creative solutions to overcome these difficulties. - Highlights: • First paper analysing the experience of small project developers in South Africa. • Project developers in South Africa are puzzled with the long process. • South African big businesses are reluctant to engage in CDM projects. • Small-scale project developers spot opportunities and find creative solutions to overcome difficulties. • Also, we saw learning processes of South African administration in support of CDM projects

A Guide to Bundling Small-scale CDM Projects

Small-scale renewable energy and energy efficiency projects that fit the development needs of many developing countries, can potentially be supported via the Clean Development Mechanism (CDM), one of the Kyoto Protocol's flexible mechanisms for tackling climate change. However, there is concern that due to high transaction costs, as well as many existing barriers, very few investments will be made in small-scale projects, which are often the most suitable development option in countries such as India. In view of this, the 'bundling' together of appropriate small-scale projects on a regional basis has been proposed as a way in which funding can be leveraged from international sources and transaction costs reduced. IT Power, IT Power India and the Energy research Centre of the Netherlands (ECN) are carrying out a 2-year project to establish the capacity within India to enable individual small scale projects to be bundled as a single CDM project. Overall objectives are to develop the necessary institutional capabilities to formulate and implement small scale CDM projects in India; to provide a guide on how to bundle small scale projects under the CDM in developing countries; and to raise the awareness of the potential for investment in small scale energy projects which can gain funding through the CDM

The Kyoto Protocol and the Clean Development Mechanism (CDM) came into force on 16th February 2005 with its ratification by Russia. The increasing momentum of this process is reflected in more than 100 projects having been submitted to the CDM Executive Board (CDM-EB) for approval of the baselines and monitoring methodologies, which is the first step in developing and implementing CDM projects. A CDM project should result in a net decrease of GHG emissions below any level that would have resulted from other activities implemented in the absence of that CDM project. The 'baseline' defines the GHG emissions of activities that would have been implemented in the absence of a CDM project. The baseline methodology is the process/algorithm for establishing that baseline. The baseline, along with the baseline methodology, are thus the most critical element of any CDM project towards meeting the important criteria of CDM, which are that a CDM should result in 'real, measurable, and long term benefits related to the mitigation of climate change'. This guidebook is produced within the frame work of the United Nations Environment Programme (UNEP) facilitated 'Capacity Development for the Clean Development Mechanism (CD4CDM)' Project. This document is published as part of the projects effort to develop guidebooks that cover important issues such as project finance, sustainability impacts, legal framework and institutional framework. These materials are aimed to help stakeholders better understand the CDM and are believed to eventually contribute to maximize the effect of the CDM in achieving the ultimate goal of UNFCCC and its Kyoto Protocol. This Guidebook should be read in conjunction with the information provided in the two other guidebooks entitled, 'Clean Development Mechanism: Introduction to the CDM' and 'CDM Information and Guidebook' developed under the CD4CDM project.

2014-01-01

Highlights: • Concerns and issues in sustainability of CDM forestry projects are reviewed. • Ecological restoration is suggested to be integrated in the CDM framework. • As an ecosystem supporting service, soil restoration on degraded land is of primary importance. • Regenerating forests naturally rather than through monoculture plantations is suggested. • Potential social impacts of ecological restoration are discussed. - Abstract: The Clean Development Mechanism (CDM) is proposed to reduce greenhouse gas emissions and promote sustainable development. CDM forestry projects should contribute to mitigation of climate change through afforestation and reforestation (A/R) activities on degraded land in developing countries. However, like other types of CDM projects, the forestry projects have encountered a number of concerns and critiques. Appropriate approaches and concrete aims to achieve long-term sustainability have been lacking, and reforms have therefore been called for. The aims of this paper are to examine the published information relevant to these concerns, and frame appropriate approaches for a more sustainable CDM. In this review, as a first step to tackle some of these issues, ecological restoration is suggested for integration into the CDM framework. Essentially, this involves the restoration of ecosystem supporting service (soil restoration), upon which forests regenerate naturally rather than establishing monoculture plantations. In this way, forestry projects would bring cost-effective opportunities for multiple ecosystem services. Potential approaches, necessary additions to the monitoring plans, and social impacts of ecological restoration in CDM projects are discussed

One of the dual objectives of the Clean Development Mechanism (CDM) of the Kyoto Protocol is to promote sustainable development in the host countries. With different CDM indicators for 58 CDM host countries over 2005-10, this paper empirically assesses whether CDM project development fulfils...... this objective of sustainable development. Using a unique dynamic panel data method based on long-differences of the model, this research provides evidence in support of significant contribution to sustainable development of CDM projects in the host countries. It sheds light on the role of CDM projects...... in the process of sustainable development with clear policy implications for developing countries and the wider world....

Rethinking the Role of Development Banks in Climate Finance: Panama’s Barro Blanco CDM Project and Human Rights

Directory of Open Access Journals (Sweden)

Beatriz Felipe Pérez

2016-06-01

Full Text Available Development banks are key actors in climate finance. During the last decades, they have increased the funding of climate change related projects, especially those under the Clean Development Mechanism (CDM. Defined in Article 12 of the Kyoto Protocol, the CDM aims at contributing to climate change mitigation while assisting in achieving sustainable development. However, many CDM projects have caused environmental damage and human rights abuses that especially affect the most vulnerable people. Located in Panama, the Barro Blanco hydro-power dam exemplifies the complex interrelationship of climate financing, development policies, the political and economic national context and human rights. Through the analysis of the role of development banks in climate finance, especially in the context of CDM projects, this paper aims (1 to clarify the role of development banks in climate finance, (2 to shed light on the vulnerable situation of the people affected by these projects, (3 to highlight the gaps in both the CDM rules and the development banks’ safeguard policies concerning the protection of human rights and the prevention of environmental abuses, and (4 to give a current example of this complex situation through the Barro Blanco case study. This paper argues that the manifold and often competing national and international legal and political layers of climate change mitigation projects repeatedly leave project affected people vulnerable to human rights violations without adequate safeguards and mechanisms to effectively articulate their interests, protect their rights and promote access to justice.

Technology and knowledge transfer from Annex 1 countries to non Annex 2 countries under the Kyoto Protocol's Clean Development Mechanism (CDM). An empirical case study of CDM projects implemented in Malaysia

2008-10-15

The CDM constitutes a central element in political discussions on climate change concerning means to facilitate transfer of technology and knowledge, regarding greenhouse gas (GHG) mitigation technologies, from Annex 1 countries to Non Annex 1 countries. The purpose of this thesis is therefore to answer the question of what role the CDM plays in relation to transfer of technology and knowledge. The thesis relies on multiple sources of qualitative data and is conducted as a multiple case study of thirteen CDM projects implemented in Malaysia. It focuses on the companies involved in implementation of specific technologies in these projects and the channels that can facilitate the transfer process. The aim of the thesis is therefore to provide insights into the dynamics of technology transfer at the micro-level. An analytical framework is put forward on which it can be concluded that the CDM only plays a role in one out of the thirteen projects examined. The thesis may contribute to provide a background on which future provisions concerning technology transfer in the CDM, and/or other mechanisms that involve GHG mitigation activities in Non Annex 1 countries.

The Clean Development Mechanism (CDM) contributes to sustainability and to sustainable development in those countries where CDM projects are developed and helps the countries from Annex I to achieve their reduction targets to Greenhouse Gases. This paper presents a proposal of a social and environmental sustainability diagnosis making use of a tool called Social and Environmental Evaluation Matrix - MADSA{sup R}. Its purpose is to establish and measure appropriate sustainable indicators to evaluate projects to ensure development benefits of CDM projects in host countries in consistency with Annex I countries developmental goals. MADSA{sup R} methodology allows a definition of a social and environmental baseline to MDL projects, and provides information to any interested group of people, from stockholders to local community; showing its results. It allows a greater clients', stockholders' and investor's trust as it measures the development so it makes possible the diagnosis and the comparison between all phases of the project. It also contributes to a continuous improvement through the participation of benefit groups in the diagnosis. Besides being an evaluation method and a management tool, this proposal looks for being a reference as an indicator pattern that evaluates the sustainable social and environmental development of CDM projects.

Clean development mechanism: Perspectives from developing countries

Energy Technology Data Exchange (ETDEWEB)

Sari, Agus P.; Meyers, Stephen

1999-06-01

This paper addresses the political acceptability and workability of CDM by and in developing countries. At COP-3 in Kyoto in 1997, the general position among developing countries changed from strong rejection of joint implementation to acceptance of CDM. The outgrowth of CDM from a proposal from Brazil to establish a Clean Development Fund gave developing countries a sense of ownership of the idea. More importantly, establishing support for sustainable development as a main goal for CDM overcame the resistance of many developing countries to accept a carbon trading mechanism. The official acceptance of CDM is not a guarantee of continued acceptance, however. Many developing countries expect CDM to facilitate a substantial transfer of technology and other resources to support economic growth. There is concern that Annex I countries may shift official development assistance into CDM in order to gain carbon credits, and that development priorities could suffer as a result. Some fear that private investments could be skewed toward projects that yield carbon credits. Developing country governments are wary regarding the strong role of the private sector envisioned for CDM. Increasing the awareness and capacity of the private sector in developing countries to initiate and implement CDM projects needs to be a high priority. While private sector partnerships will be the main vehicle for resource transfer in CDM, developing country governments want to play a strong role in overseeing and guiding the process so that it best serves their development goals. Most countries feel that establishment of criteria for sustainable development should be left to individual countries. A key issue is how CDM can best support the strengthening of local capacity to sustain and replicate projects that serve both climate change mitigation and sustainable development objectives.There is support among developing countries for commencing CDM as soon as possible. Since official commencement must

The clean development mechanism (CDM) of the Kyoto Protocol is designed not only to mitigate greenhouse gas emissions (GHG) but also to contribute locally to sustainable development. As a market-based mechanism, CDM has the potential to channel private investments into development activities...... with economic, social, and environmental benefits. Unfortunately, investments have tended to flow where CDM activities provide higher returns with limited economic and political risks, that is, outside of least developed countries (LDCs). To date, only a handful of LDCs have been able to participate in the CDM...

Why the CDM can reduce carbon leakage

International Nuclear Information System (INIS)

Kallbekken, S.

2006-04-01

Carbon leakage is an important concern because it can reduce the environmental effectiveness of the Kyoto Protocol. The Clean Development Mechanism, one of the flexibility mechanisms allowed under the protocol, has the potential to reduce carbon leakage significantly because it reduces the relative competitive disadvantage to Annex B countries of restricting greenhouse gas emissions. The economic intuition behind this mechanism is explored in a theoretical analysis. It is then analyzed numerically using a CGE model. The results indicate that, assuming appropriate accounting for leakage and under realistic assumptions on CDM activity, the CDM has the potential to reduce the magnitude of carbon leakage by around three fifths

Biodiesel, renewable energy source, has been adopted by several countries as a possible substitute for fossil fuels. Brazil, by its own, included oil and fat derived biofuel in its energetic matrix through National Politics for Biofuel Use and Production (NPBUP), issue in Law n. 11.097 of 01/13/2005. Many studies demonstrate the contribution of biofuel for Greenhouse Gases reduction, what turns projects using it into possible candidates for Clean Development Mechanism (CDM), instrument described in Kyoto Protocol. With purpose of studying the Brazilian potentiality of the insertion of biofuel into CDM projects, this report approaches many aspects related to CDM, as well the terms for being accepted as so. Through bibliographic review were listed the possibilities and the restraints for including biofuel in carbon market resulted, principally, by the obligation of its use; what goes against the principle of voluntary, for seen in the Protocol. I concluded analyzing the advantages of biofuel comparatively to environmental issues, emphasizing the necessity of making viable its entrance into carbon credits market. (author)

As an advanced modality introduced in 2005, the Programmatic CDM (POA) is expected to address asymmetries of participation, especially of very small-scale project activities in certain areas, key sectors and many countries with considerable potential for greenhouse gas emission reductions, not reached by the traditional single-project-based CDM. Latest experiences with POAs and the recently finalized official guidance governing the Programmatic CDM are the grassroots of this Primer, which has the purpose of supporting the fully understanding of rules and procedures of POAs by interpreting them and analyzing real POA cases. Professional and experts from the public and private entities have contributed to the development of this Primer, produced by the UNEP Risoe Centre, as part of knowledge support activities for the Capacity Development for the CDM (CD4CDM) project. The overall objective of the CD4CDM is to develop the capacities of host countries to identify, design, approve, finance, implement CDM projects and commercialize CERs in participating countries. The CDM4CDM is funded by the Netherlands Ministry of Foreign Affairs. (author)

Full Text Available Public plantations (PPs and Community planted forests (CPFs are inimitable types of participatory forest management practices in Nepal, but their eligibility issues under the framework of clean development mechanism (CDM and reducing emission from the deforestation and forest degradation mechanism (REDD+ are not evaluated. So, to explore the management system of PP and CPF, we compared forest carbon stocks in plantations and evaluated these plantations under these mechanisms as objectives of this research. The relevant documents were revised and altogether 55 samples were collected from Shreepur, Banauta and Bisbity PPs and Sita, Ramnagar and Jogikuti CPFs, in Mahottary district, Nepal. The equation of Chave et al was used to calculate the biomass, which was further converted into carbon. Meanwhile, management practices were evaluated under the framework of CDM and REDD+. The PPs are public land managed, especially by disadvantaged communities, while CPFs are the patches of national forest managed by users. The variation in carbon stock was found to be highest (148.89 ton ha-1 in Sita CPF and lowest (30.34 ton ha-1 in Bisbitty PP. In fact, it is difficult to certify plantations under CDM, due to its complexity, but they can easily be candidate to the REDD+ mechanism, if they are bundled with large forest blocks.

Carbon quota price and CDM potentials after Marrakesh

The Kyoto Protocol sets quantified GHG emission reduction commitments for Annex I Parties. But their emission reduction requirements related to BAU projections, one of the key factors to effect on future carbon market, are uncertain. Both the decisions made in Bonn and Marrakesh would have further consequences for how the future carbon market will take shape. This paper, with application of the carbon emission reduction trading model, evaluates future carbon quota price and Clean Development Mechanism (CDM) potentials under different BAU projections, and does sensitivity analysis on carry-over of AAUs, CERs and ERUs, implementation rate, transaction cost, holding of CERs in Non-Annex I Parties, etc. to assess the impacts of relevant decisions of COP6-bis and COP7 on the carbon market. Under different BAU projections, future carbon quota price and CDM potentials could vary widely. Carry over of AAUs, CERs, ERUs, and holding of CERs in Non-Annex I Parties could raise both quota price and total CDM potentials considerably. Implementation rate could have big impacts on both carbon quota price and CDM potentials, especially for the cases formerly with relatively high CDM potentials, and it could also change the regional distribution of CDM potentials. Transaction cost's effect on the carbon market would be comparatively low, but would become unignorable in the market whose quota price is low. It would lead to a downward trend in price while upward in CDM potentials when increasing the implementation rate or lowering transaction cost. Withdrawal of USA would dramatically shrink carbon price and credit amount, and large numbers of hot air and sink credits would further greatly crowd out the CDM projects; carry over of AAUs, CERs and ERUs, holding of CERs in Non-Annex I Parties, prompt start of CDM projects, etc., would, however, enhance the total CDM credits to ensure more investment and technology flow to developing countries to promote their sustainable development

China is expected to reach record growth by 2020 in the energy sector by at least doubling its electricity generation capacity. In order to protect the environment and foster economic development, China will greatly benefit from transfers of state-of-the-art power generation technologies through international agreements such as the Clean Development Mechanism (CDM). However, a buyer-driven carbon market and a highly competitive environment due to more cost-effective projects attribute to China's need to achieve a balance between sustainability and profitability for CDM projects implemented in China. In the CDM Tax/Subsidy Optimization Model (CDMTSO Model) here developed, a sustainable development assessment method evaluates the CDM projects' economic and environmental benefits and an optimization program returns tax/subsidy rates at which the greatest number of CDM technologies becomes viable and where 'better' CDM projects can be the most profitable, bringing China's development on a more sustainable path. The results show that the CDMTSO Model brings the sustainable CDM projects' Internal Rate of Return closed to 10%. If a discount rate of 9% is considered, it allows three clean energy technologies (natural gas combined cycle, wind energy, and hydropower) to become economically viable and the environmental costs avoided are increased by 37%

Potential impacts of CCS on the CDM

Bakker, S; Mikunda, T.; Rivera Tinoco, R.

2011-02-01

CO2 capture and storage can ensure that stringent climate change mitigation targets are achieved more cost-effectively. However, in order to ensure a substantial role for CCS, deployment of CCS is required on a significant global scale by 2020. Currently, the CDM is the only international instrument that could provide a financial incentive for CCS in developing countries. In December 2010 it was decided that CCS could in principle be eligible under the CDM, provided a number of issues are resolved, including non-permanence, liability, monitoring and potential perverse outcomes. The latter issue relates to the concern that that CCS projects could flood the CDM market, thereby crowding out other technologies that could be considered more sustainable. This report, therefore, aims to quantify the possible impact of CCS on the CDM market, in order to assess the relevance of the CDM market objection. However, the analysis in the report is also valid for the role of CCS in other types of international support mechanisms. The first result of this study is a marginal abatement cost curve (MAC) for CCS in developing countries for 2020. Based on existing MAC studies, the IEA CCS Roadmap and an overview of ongoing and planned CCS activities, we compiled three scenarios for CCS in the power, industry and upstream sector, as shown below. The major part of the potential below $30/tCO2eq (70 - 100 MtCO2/yr) is in the natural gas processing sector. Using the MACs for the CDM market, we estimate the economic potential for CCS projects to be 4-19% of the CDM credit supply in 2020. The potential impact inclusion of CCS in the CDM may have is assessed by using several possible CER supply and demand scenarios, as well as scenarios related to market price responsiveness and the role of CDM in the post-2012 carbon market. The impact is estimated to be between $0 and $4 per tonne of CO2-eq, with three out of four scenarios indicating the lower part of this range.

2007-07-01

The Clean Development Mechanism (CDM) has developed during its first period of implementation, a distinctive set of patterns. The authors thought of concentrating on the CDM analysis in order to highlight potential remedies or reasons for given bottlenecks. In order to establish a sort of extensive SWOT analysis for CDMs, all the 356 projects actually (November 2006) registered at UNFCCC were examined, together with all the about 1000 PDDs presented to the UNFCCC but not registered yet. The CDM projects have been studied trying to cluster projects according to relevant characteristics, both from a technical and an economic point of view. Chosen indicators are meant to identify: more convenient/more diffused energy system for a CDM; reasons for a geographical distribution of different types of projects; potentials for a future exploitation of lower used technologies in CDM. Conclusions are drawn and appropriate tables and graphs presented. (1) the Baseline Emission Factor, combined to economic patterns, is the pivotal factor that characterizes both choices of host country and technology; (2) some technologies can exploit appropriately CDM scheme, whilst other technologies, are constrained by it. (3) there are still some important weak points: grouping of non Annex I countries; crediting period; criteria for the evaluation of sustainable development. (auth)

Issues related to a programme of activities under the CDM

Emissions of CO2 from the energy and land-use change and forestry sectors are responsible for the majority of emissions in non-Annex I Parties to the UNFCCC. Tackling greenhouse gas (GHG) emissions from these sectors is a key to slowing the growth in GHG emissions in non-Annex I countries. Implementing Clean Development Mechanism (CDM) projects can help achieve this aim, while also assisting non-Annex I countries to move towards sustainable development and Annex I countries achieve their emission commitments under the Kyoto Protocol. There has been rapid progress in the CDM over the last year - in terms of the number of projects in the pipeline and registered, and in terms of credits issued. However, some important sectors are notable by their small share in the CDM portfolio. Several countries have also called attention to the need to accelerate the process of approving CDM methodologies and projects. In order to improve the effectiveness of the CDM to achieve its dual objectives, the COP/MOP agreed a decision on 'further guidance relating to the clean development mechanism. This decision lays out guidance on how to improve the operation of the CDM, and includes provisions that allow: (1) Bundling of project activities; and (2) Project activities under a programme of activities, to be registered as a CDM project activity. At present, of the 172 currently registered CDM project activities, 27 involve programmes or bundles. These project activities can include more than one project type, be implemented in several locations, and/or occur in more than one sector. This paper assesses how project activities under a programme of activities under the CDM (referred to here as PCDM) could help to increase the effectiveness of the CDM by encouraging a wide spread of emission mitigation activities. This paper also explores the key issues that may need to be considered for the PCDM concept to be further implemented. The paper concludes that: (1) Key concepts and issues

Carbon market risks and rewards: Firm perceptions of CDM investment decisions in Brazil and India

2012-01-01

The carbon market experiences of Brazil and India represent policy success stories under several criteria. A careful evaluation, however, reveals challenges to market development that should be addressed in order to make the rollout of a post-2012 CDM more effective. We conducted firm-level interviews covering 82 CDM plants in the sugar and cement sectors in Brazil and India, focusing on how individual managers understood the potential benefits and risks of undertaking clean development mechanism (CDM) investments. Our results indicate that the CDM operates in a far more complex way in practice than that of simply adding a marginal increment to a project's internal rate of return. Our results indicate the following: first, although anticipated revenue played a central role in most managers' decisions to pursue CDM investments, there was no standard practice to account for financial benefits of CDM investments; second, some managers identified non-financial reputational factors as their primary motivation for pursuing CDM projects; and third, under fluctuating regulatory regimes with real immediate costs and uncertain CDM revenue, managers favored projects that often did not require carbon revenue to be viable. The post-2012 CDM architecture can benefit from incorporating these insights, and in particular reassess goals for strict additionality and mechanisms for achieving it.

Point Climat no. 20 'CDM Policy Dialogue: a traditional 'treatment' coupled with new 'prescriptions' '

Among the publications of CDC Climat Research, 'Climate Briefs' presents, in a few pages, hot topics in climate change policy. This issue addresses the following points: As the Clean Development Mechanism (CDM) reached the milestone billionth CER issued and the secondary CER price tipped below 2 euros, the recommendations of the High Level Panel on the CDM Policy Dialogue published on 11 September 2012 could not be timelier. By focusing on the current supply-demand disequilibrium that threatens the very survival of the CDM, the Panel extended its recommendations beyond the traditional scope of CDM reform. The Panel's ambition to pro-actively engage with other climate initiatives such as the Green Fund and regional markets is also innovative. Indeed, the CDM toolbox enriched by 10-years of experience stands to apply to or be partly recycled through new mechanisms. Along the 51 recommendations from the Policy Dialogue, there are calls for further standardization and streamlining, together with both old and new ideas on governance and contribution of the CDM to sustainable development

Clean development mechanism (CDM) is expected to facilitate technology transfer from developed to developing countries as well as to economically reduce greenhouse gas emissions. In this article, we explore effective institutions to activate CDM projects. For this purpose, we have estimated internal rate of return (IRR) and other indicators on profitability for 42 CDM or JI projects, taking account of volatilities in the price of certified emission reductions (CER). As a result of Monte Carlo simulations, expected values and standard deviations in the IRR of the projects were quantitatively shown. Then we evaluated various risks in CDM, concluding that diversification of investment is an effective way to suppress these risks. Therefore securitization of CDM finance is proposed as a means of facilitating the diversification of investment. Namely, we present the concept of a CDM bond, which is a project bond with CER. We also investigated the role of governments to suppress risks in CDM. Referring to CERUPT, initiated by the Netherlands' government, the institution of 'insured CERUPT' is proposed to suppress downside risks in the IRR of the projects. We concluded that it is possible to make CDM projects viable by the 'insured CERUPT' and CDM bond

Proposals for joint initiatives put forward by participants at the Clean Development Mechanisms Conference included (1) the development of regional guidelines to assist governments in setting regulatory framework for projects to qualify as CDMs, (2) development of regional baselines and regional performance indicators for social benefit and sustainable development, (3) a specific project in Mexico to test the CDM framework and eligibility criteria, (4) development of bilateral agreements between governments, (5) staff exchanges between associations and governments, (6) government recognition for private sector actions such as a letter affirming that certified emission reductions would be accepted for commitments, (7) sharing of information on websites, and (8) capacity building, training programs and workshops. The Conference also identified common ground and shared interest in CDM initiatives among participants, and readiness to explore joint ventures and technology transfer opportunities. There is wide-spread agreement on the need to resolve uncertainties of CDM, such as baseline and additionality; monitoring, reporting, certification; buyer/seller liability; adaptation levy for international emissions trading, joint implementation and clean development mechanism transactions. Significant consensus exists regarding benefits of 'learning by doing' and the need for minimizing transaction costs and risks. Baseline and Additionality are recognized as the critical issues, with social benefits, sustainable development aspects of projects, and the critical nature of integrity, technical expertise, and track record of both partners as close seconds. The importance of framework arrangements, host country approval, clear designation of responsibility and authority to approve projects, the need for specific guidelines and specific approval procedures, country-to-country agreements and national crediting arrangement are recognized by all participants.

The Clean Development Mechanism (CDM), as defined in the Kyoto Protocol, has two objectives: to promote sustainable development in host developing countries, and to improve global cost-effectiveness by assisting developed countries in meeting their Kyoto targets. The aim of this paper is to explore the background of the CDM and discuss to what extent its current design allows it to achieve its dual objective. The first part of the paper is a literature review that includes descriptions of the flexibility mechanisms under the Kyoto Protocol; the CDM's market potential, and the issues of cost-effectiveness and sustainable development. In the second part of the paper, we discuss to what extent there is a conflict between cost-effectiveness and sustain ability, and whether the two objectives of the CDM can be achieved simultaneously. We develop a set of indicators to evaluate non-carbon benefits of CDM projects on the environment, development, and. equity, and show how these indicators can be used in practice by looking at case studies of CDM project candidates in the energy sector from Brazil and China. We demonstrate that for some CDM projects there is a trade-off between cost-effectiveness, in terms of a low quota price, and a high score on sustain ability indicators. We have reason to believe that the size of the CDM market in some studies is over-estimated since transaction costs and the challenge of promoting sustainable development are not fully accounted for. Also, we find that the proposed set of indicators can be a necessary tool to assure that sustain ability impacts of CDM projects are taken into consideration. (author)

Modelling the impacts of CDM incentives for the Thai electricity sector

International Nuclear Information System (INIS)

Weiss, Philipp; Lefevre, Thierry; Moest, Dominik

2008-01-01

The CDM Executive Board recently took a positive decision on programmatic CDM, also known as a CDM Programme of Activities. This prompts the author to present a new tool that has been developed recently for the Thai electricity market. The Renewable Energy Development (RED) Model, initially developed in the framework of the DANIDA funded project: Promotion of Renewable Energy in Thailand (PRET), at the Ministry of Energy of Thailand, was designed for the modelling of different incentive schemes and their effects on the Thai power system for the promotion of renewable energy technologies (RETs). Within this article, an extension of the existing RED model, including the CDM as additional incentive measure, is presented (RED-CDM). Along with the project-based approach, also a sectoral and programmatic approach is included as well. Several scenarios developed with the RED-CDM model show the influence of different incentive mechanisms on the Thai power market and their potentials for reaching the policy targets stated in the Energy Strategy of Thailand for Competitiveness. The main results show that reaching the policy targets is possible, while the price can be extremely high if the targets are to be achieved on schedule. Another important result is that a sectoral CDM approach could help financing about 20% of the incentives needed for a shift towards a more sustainable power grid, if the certified emission reductions (CERs) are sold at a price of 15 Euro/ton

Success Factors for Clean Development Mechanism Implementation in Malaysia

2013-09-01

Full Text Available The Clean Development Mechanism (CDM, established under the Kyoto Protocol, is one of the market-based mechanisms developed to assist industrialized countries mitigate greenhouse gas (GHG emissions, achieve emission reduction targets, and at the same time promote sustainable development in developing countries. The CDM, which provides flexibility and costeffectiveness in meeting GHG emission reduction targets, has captured interest globally. CDM implementation is expected to generate benefits, give developing countries a sense of ownership, and share the global load in tackling global warming and climate change. However, CDM implementation faces several complications. The successful participation of developing countries in emission reduction projects presents ongoing challenges, which inhibit their drive towards sustainable development goals. Through a comprehensive review of the literature and theoretical analysis, several factors have been identified as significant to successful CDM implementation in Malaysia. These success factors, which include regulation and a legal framework, competitive advantage, green supply chain, ethical values, financial benefits, and technology transfer, are presented and the importance of each factor is discussed.

Etude Climat no. 37 '10 lessons from 10 years of the CDM'

International Nuclear Information System (INIS)

Shishlov, Igor; Bellassen, Valentin

2012-01-01

Among the publications of CDC Climat Research, 'Climate Reports' offer in-depth analyses on a given subject. This issue addresses the following points: The Clean Development Mechanism (CDM) is the first and by far the largest carbon offset instrument in the world. To date, it is the only market based on an environmental commodity which managed to attract several billions of euros of private capital on an annual basis. Being the first-of-a-kind climate change mitigation instrument, the CDM followed a 'learning by doing' pattern undergoing numerous reforms throughout its more than 10-year history. Although the post-2012 fate of the mechanism remains uncertain, one should not 'throw out the baby with the bath water' as the lessons from the CDM experience may be useful not only for the CDM reform but also for new market instruments

Moving from the CDM to 'various approaches'

International Nuclear Information System (INIS)

Shishlov, Igor; Bellassen, Valentin

2014-03-01

The Clean Development Mechanism (CDM) facilitated the emergence and deployment of low-cost greenhouse gas (GHG) abatement technologies such as destruction of industrial gases and capturing methane from landfills and coal mines. Some of these technologies are now ripe to 'graduate' from the CDM into other, more mainstream, economic tools. The first such step was taken in September 2013 when the G20 leaders agreed to phase out HFCs - highly potent greenhouse gases - including HFC-23 that was the focus of 19 CDM projects. A potential HFC-23 abatement fund under the Montreal Protocol could reduce up to 1.8 Gt CO 2 e by 2020 at a cost of under US$0.2 per ton of CO 2 e, i.e. much cheaper than the price paid to CDM projects through carbon crediting. The next potential candidate technology to 'graduate' from the CDM is the abatement of nitrous oxide (N 2 O) emissions in the chemical industry, which have already been placed on the agenda of the Montreal Protocol.

Trojan horse or horn of plenty? Reflections on allowing CCS in the CDM

International Nuclear Information System (INIS)

Coninck, Heleen de

2008-01-01

The discussion around allowing CO 2 capture and geological storage (CCS) into the Kyoto Protocol's Clean Development Mechanism (CDM) is important, as the CDM is currently the only structural incentive for reducing greenhouse gas emissions in the developing world. Without the potential incentives given by the CDM, CCS in developing countries will only take place sporadically in niche sectors. The debate around CCS in the CDM has developed into a highly polarised discussion, with a deep divide between proponents and opponents and no view on reconciliation between the various perspectives. Environmental organisations and several developing-country parties in the climate negotiations are increasingly vehemently opposed against CCS in the CDM, and industrialised countries, several large fossil-fuel-dependent developing countries and industry view CCS as a natural option under the CDM, provided some surmountable technical and procedural barriers are taken care of. This paper argues that the efforts of those trying to bring the discussion to a close by solving technical and procedural issues around CCS in the CDM will not lead to agreement because of underlying convictions of all stakeholders. Six convictions are identified and discussed. Based on the discussion of the convictions of both opponents and proponents, research needs and a potential negotiation package are suggested. The research needs are primarily in the field of the CDM market impacts of CCS, the issue of enhanced oil emission accounting, and sustainable development aspects, and particularly whether developing countries could actually benefit from technological leadership in the field of CCS, or whether they will be worse off. Devoting attention to the identified convictions could provide information for a more acceptable negotiation package on CCS in the CDM. (author)

Does the Gold Standard label hold its promise in delivering higher Sustainable Development benefits? A multi-criteria comparison of CDM projects

International Nuclear Information System (INIS)

Drupp, Moritz A.

2011-01-01

The Clean Development Mechanism (CDM) has a twin objective: to help developed countries reduce GHG emissions, and to support developing countries in achieving Sustainable Development (SD). As a response to the widespread criticism of the CDM's unsatisfactory SD record, initiatives have developed premium labels like the Gold Standard, which applies two additional 'screens' to filter CDM projects for higher SD benefits. In order to determine whether Gold Standard projects can be associated with higher local SD benefits, this paper evaluates the potential benefits of 48 CDM projects using a multi-criteria method and building on existing work. The 18 evaluated Gold Standard projects are compared to a 'representative portfolio' of 30 unlabeled CDM projects in order to capture the 'full' effect of the additional Gold Standard requirements, which is further decomposed into the two 'screen' effects. The results suggest that Gold Standard Certified Emission Reductions can be associated with higher potential local SD benefits when compared to the 'representative portfolio' of unlabeled CDM projects, while the comparison of projects of the same type remains inconclusive. The results support previous findings showing that renewable energy projects may deliver comparatively high SD benefits. - Research highlights: → This study evaluates and compares the potential contribution of unlabeled- and Gold Standard labeled CDM projects to Sustainable Development (SD), extending the previously assessed projects as well as the methodological approach. → Gold Standard labeled Certified Emission Reductions (CER) can be associated with higher potential SD benefits compared to unlabeled projects. → A decomposition analysis shows that the Gold Standard s SD surplus must be primarily attributed to the favorable contribution of renewable energy projects to SD. → Policy makers might thus shift incentives towards renewable energy projects and buyers of CERs may shift their offset

Canada's potential role in the Clean Development Mechanism

Pape-Salmon, A.

2000-01-01

The role that Canada might play in the Kyoto Protocol's Clean Development Mechanism (CDM) is discussed. The CDM prescribes the way in which industrialized countries could create emission reduction credits for greenhouse gas emission reduction projects in developing countries which, in turn they could use to meet their own commitments and possibly reduce their cost of compliance with the Kyoto Protocol. While Canada does not see itself as a CDM project investor, it strongly supports private sector involvement in the CDM and believes that it has a role to play in assisting CDM investments by the Canadian private sector by facilitating desirable outcomes via international negotiations on the rules and modalities for the CDM which would minimize transaction costs; give prominence to aspects that Canada recognizes as necessary precursors to mobilizing private sector involvement in CDM activities; maximize the flexibility for use of the CDM; allow for conversion of credits between different Kyoto Mechanisms; allow for the certification of emissions sequestration from sinks; and maximize the environmental and sustainable development benefits of CDM projects. Canada also supports, along with the other members of the 'Umbrella group', the fewest possible restrictions and significant autonomy to the private sector to implement a variety of project activities in developing countries. This report provides a detailed examination of the Canadian government's views on the CDM, Canada's participation in international emission reduction projects, the factors that drive Canadian demand for greenhouse gas emission reduction offsets and the potential demand for CDM offsets, Canada's greenhouse gas emission inventory and projections, the approach of Canadian corporate investors in the CDM and Canadian technology and expertise in greenhouse gas emission reductions. Various appendices to the report contain further details on a number of cooperation agreements between Canada and other

Improving the attractiveness of CDM projects through allowing and incorporating options

Carmichael, David G.; Ballouz, Joseph J.; Balatbat, Maria C.A.

2015-01-01

The paper puts forward a proposal that, within Clean Development Mechanism (CDM) projects, investors be allowed to benefit from options; this will require a CDM rule change. Through the presence of options, the downside risk resulting from low carbon prices and/or low achieved emission reductions on projects can be limited, while any upside resulting from high carbon prices and/or high achieved emission reductions can be taken advantage of. It is demonstrated that the presence of options improves the financial attractiveness of CDM projects, and this is at no detriment to any stakeholder. The flow-on from the proposal is that more CDM projects should be realisable if options are available, and this in turn will lead to reduced global emissions and improved sustainability. The proposal is supported by the necessary theory and is demonstrated on two registered CDM projects, one on hydropower and one on wind power. - Highlights: • The paper proposes that options be allowed within CDM projects. • Introducing options will require a CDM rule change. • Options improve the financial attractiveness of CDM projects. • Allowing options comes at no cost or detriment to any party. • Allowing options is a win–win situation to both society and the project proponent.

Bhabha, the architecture of the Indian Nuclear programme felt a need for proto-type development and precision manufacturing facility to fulfill the requirements of mechanical components in establishing the manufacturing capability for the successful and self sustained nuclear programme. Centre for Design and Manufacture (CDM) hitherto known as CWS was established in 1964 to cater to the specific requirements of DAE and other associated units like ISRO, DRDO. Since then CDM has made multiple technological achievements and changes towards high quality products. The acquisition of up-to-date machines during High-Tech facility under VIII Plan project and Advance Precision Fabrication facility under IX Plan project has changed the capability of CDM towards CAD, CAM, CAE and CNC machining centres. Considering the rapid growth in the design and manufacturing, it was renamed as Centre for Design and Manufacture in March 2002, with the mission of quality output through group effort and team work

The Clean Development Mechanism (CDM) potentially offers a major opportunity for catalysing technology leapfrogging in the South. A CDM which delivers genuine incentives for investment in clean energy technologies and innovative energy solutions could become the first step in shifting towards a development model based on the delivery of sustainable energy services. Conversely, according to a recent analysis for WWF, a CDM regime which allows easy credits for conventional technologies will merely serve to reinforce the current trend towards increased carbon dependency in the South, at the same time as it allows industrialised countries to continue to increase greenhouse gas emissions at home

The Clean Development Mechanism and neglected environmental technologies

International Nuclear Information System (INIS)

Kim, Jung Eun; Popp, David; Prag, Andrew

2013-01-01

The Clean Development Mechanism (CDM) provides an institutional framework for developed countries to support projects that reduce greenhouse gas emissions in developing countries. Are the technologies promoted those most needed by the recipient countries? We address this question by first reviewing Technology Needs Assessments prepared by developing countries, and then comparing the stated needs to the technologies most frequently promoted via CDM. While there appears to be a good match between requested technologies and those used in CDM, desired technologies such as solar energy for remote locations, biofuels, improved cooking stoves, and efficient lighting appear “neglected” by CDM. Nonetheless, a review of costs for these technologies suggests that many could be cost effective for developing countries. For projects requiring wide dispersal of household items, such as cooking stoves or lighting, the administrative burdens of CDM provide a hurdle. In other cases, difficulties quantifying the ancillary benefits of these projects hinder the promotion of these technologies. We conclude with possible explanations for why these technologies are neglected and suggestions for future research. - Highlights: ► We identify technologies desired by developing countries but not provided via CDM. ► Solar PV is neglected due to high costs. ► The CDM process provides a hurdle for improved cooking stoves and efficient lighting. ► Implications for CDM and climate policy are discussed

Climate Change Policy Measures in Japan: NEDO's Activities to Promote CDM/JI

The Kyoto Protocol, which obliges developed countries to reduce emissions of greenhouse gases (GHG), was adopted at the third session of the conference of the parties to the United Nations Framework Convention on Climate Change (UNFCCC) in Kyoto, Japan, on I I December 1997. Japan subsequently ratified the Kyoto Protocol in 2002 and is required thereunder to reduce GHG emissions by 6% below 1990 levels by 2008-2012. Japan, having already tackled development and promotion of energy conservation technologies after the second oil crisis, emits the lowest level of CO 2 of developed countries approximately 9.4 tons per capita in the year 2000. Consequently, Japan is able to contribute to CO 2 emissions reduction in developing economies as well as in economies in transition by application of Japan's energy conservation technologies. Because the Clean Development Mechanism (CDM) and Joint implementation (JI) of the Kyoto Mechanisms are efficient tools, the Japanese government's policy towards emission reduction makes active use of CDM/JI, thereby supporting domestic efforts in realizing Japan's reduction commitment. The Ministry of Economy, Trade and Industry (METI) of Japan is one of the key ministries to administer Governmental policy making on climate change, and is undertaking establishment of a system to facilitate the Kyoto Mechanisms. The New Energy and Industrial Technology Development Organization (NEDO), under the jurisdiction of METI, supports CDM and JI project activities implemented by Japanese private sector enterprises. In this report, the authors briefly introduce climate change policy measures in Japan and NEDO's activities to promote CDM/Jl. (Author)

Full Text Available The program, ‘Reducing Emissions from Deforestation and Forest Degradation’ (REDD, which operates within the international climate change policy framework, is projected to emerge as one of the key climate change mitigation mechanisms for developing countries. The existing Afforestation/Reforestation (A/R mechanism, operating under the Clean Development Mechanism of the Kyoto Protocol to the United Nations Framework Convention on Climate Change, may prove useful for drawing lessons for the emerging REDD program, since both mechanisms represent flexible means for developed countries to achieve compliance with their mitigation targets under the Kyoto Protocol. The possible means include CDM as the basis for a project-based approach for the implementation of REDD (if adopted or the inclusion of REDD within CDM. This article compares the features of A/R CDM and REDD, identifies similarities and differences, and analyses the extent to which the former can provide guidance for the development of a carbon governance mechanism for REDD.

Overview of UNEP's CDM activities. Enhancing a more equitable regional distribution of CDM project activities

Energy Technology Data Exchange (ETDEWEB)

2007-12-15

More than thirty months after the entry into force of the Kyoto Protocol, CDM transactions continue to gain momentum. By November 2007, 2,647 CDM projects are in the CDM pipeline. Of these, 827 are registered projects, and a further 154 are inthe registration process. The CDM Executive Board (CDM EB) has issued more than 82 million Certified Emissions Reductions (CER). In terms of number of projects by type of technology, renewables CDM projects are the leading type with 62% of the pipeline. However, N{sub 2}O, HFC and PFC projects have the biggest share (34%) of CERs expected to be generated by end of first commitment period. At the same time, more and more renewables and other non-industrial gases projects are going into the pipeline increasing their share of emissions reductions to be achieved. Geographically, the distribution of CDM projects has so far not been very equitable. A limited number of countries including China, India, Brazil and Mexico have captured the largest share of the global CDM project portfolio. Specific regions in the developing world, namely Sub-Saharan Africa, have been largely bypassed by the CDM market and are struggling to attract a decent number of CDM projects. In fact, of the total 2,647 projects, only 33 projects are in Sub-Saharan Africa where 21 of these are actually in South Africa, making the distribution even more skewed. (au)

Sustainable waste management in Africa through CDM projects.

Science.gov (United States)

Couth, R; Trois, C

2012-11-01

Only few Clean Development Mechanism (CDM) projects (traditionally focussed on landfill gas combustion) have been registered in Africa if compared to similar developing countries. The waste hierarchy adopted by many African countries clearly shows that waste recycling and composting projects are generally the most sustainable. This paper undertakes a sustainability assessment for practical waste treatment and disposal scenarios for Africa and makes recommendations for consideration. The appraisal in this paper demonstrates that mechanical biological treatment of waste becomes more financially attractive if established through the CDM process. Waste will continue to be dumped in Africa with increasing greenhouse gas emissions produced, unless industrialised countries (Annex 1) fund carbon emission reduction schemes through a replacement to the Kyoto Protocol. Such a replacement should calculate all of the direct and indirect carbon emission savings and seek to promote public-private partnerships through a concerted support of the informal sector.

The study describes and discusses in detail how four CDM reform alternatives, namely discounting of emission reductions, ambitious baselines, purchase and cancellation of CERs and reinvestment of CER levies, could be integrated in a Post-2012 climate regime. The study assesses these alternatives, according to their impacts on GHG emission reductions, contribution to sustainable development, cost-efficiency, technical feasibility, incentives and distributional effects as well as negotiability. The study shows that the introduction of discounting and ambitious baselines is technically feasible but politically a massive challenge. With the help of an economic model the study shows that the introduction of reform alternatives increases the amount of emission reductions but in comparison to the current CDM the impact is rather limited. But a CDM reform can in any case increase the credibility and improve the environmental integrity of the mechanism. (orig.)

CDM potential of bagasse cogeneration in India

International Nuclear Information System (INIS)

Purohit, Pallav; Michaelowa, Axel

2007-01-01

So far, the cumulative capacity of renewable energy systems such as bagasse cogeneration in India is far below their theoretical potential despite government subsidy programmes. One of the major barriers is the high investment cost of these systems. The Clean Development Mechanism (CDM) provides industrialized countries with an incentive to invest in emission reduction projects in developing countries to achieve a reduction in CO 2 emissions at lowest cost that also promotes sustainable development in the host country. Bagasse cogeneration projects could be of interest under the CDM because they directly displace greenhouse gas emissions while contributing to sustainable rural development. This study assesses the maximum theoretical as well as the realistically achievable CDM potential of bagasse cogeneration in India. Our estimates indicate that there is a vast theoretical potential of CO 2 mitigation by the use of bagasse for power generation through cogeneration process in India. The preliminary results indicate that the annual gross potential availability of bagasse in India is more than 67 million tonnes (MT). The potential of electricity generation through bagasse cogeneration in India is estimated to be around 34 TWh i.e. about 5575 MW in terms of the plant capacity. The annual CER potential of bagasse cogeneration in India could theoretically reach 28 MT. Under more realistic assumptions about diffusion of bagasse cogeneration based on past experiences with the government-run programmes, annual CER volumes by 2012 could reach 20-26 million. The projections based on the past diffusion trend indicate that in India, even with highly favorable assumptions, the dissemination of bagasse cogeneration for power generation is not likely to reach its maximum estimated potential in another 20 years. CDM could help to achieve the maximum utilization potential more rapidly as compared to the current diffusion trend if supportive policies are introduced

Assessing technology transfer in the Clean Development Mechanism

2007-01-01

This paper presents an operational definition of technology transfer, to be applied in studies of technology transfer in projects under the Kyoto Protocol’s Clean Development Mechanism (CDM). Although the CDM has never been given an explicit mandate for transferring technologies, its contribution in this respect has both been hoped for and exacted. The discussions of technology transfer in CDM projects are however blurred by widely varying conceptions of what technology transfer is. Qu...

How could developing countries participate in climate change prevention: The Clean Development Mechanism and beyond

International Nuclear Information System (INIS)

Cavard, D.; Cornut, P.; Menanteau, P.

2001-01-01

Refusal of developing countries to commit themselves to the implementation of climate change agreements on the grounds that their cumulated emissions would have little impact on climate change, combined with their need for increase in energy consumption to meet their economic development needs, has been one of the stumbling blocks to agreement since the beginning of climate change negotiations. For these and a variety of other reasons the Clean Development Mechanism (CDM) is important for industrialized and developing countries alike since it has the promise of benefiting both parties: industrialized countries benefit from low cost emission reductions, while CDM will stimulate economic development in developing countries. This paper examines the rules of the Clean Development Mechanism in order to validate project additions (as yet unresolved), and its possible consequences on the effectiveness and the scope of the mechanism. Also examined are the three basic approaches to CDM implementation (bilateral, unilateral. multilateral), the different reactions of major developing country groups to the structure of the mechanism, and the possibilities of widening the scope of action of the CDM to include sectoral and program-based aspects. In this context, 'voluntary, non-binding' emission commitments, establishment of a reference scenario for developing countries, related concerns about sustainable development, national sovereignty issues, equity in funding and vulnerability, are some of the potential issues highlighted. 33 footnotes

As if Kyoto mattered: The clean development mechanism and transportation

International Nuclear Information System (INIS)

Christopher Zegras, P.

2007-01-01

Transportation is a major source of greenhouse gas (GHG) emissions and the most rapidly growing anthropogenic source. In the future, the developing world will account for the largest share of transport GHG increases. Four basic components drive transportation energy consumption and GHG emissions: activities (A), mode share (S), fuel intensity (I) and fuel choice (F) (ASIF). Currently, the Kyoto Protocol's clean development mechanism (CDM) serves as the main international market-based tool designed to reduce GHG emissions from the developing world. Theoretically, the CDM has the dual purpose of helping developing countries achieve 'sustainable development' goals and industrialized countries meet their Kyoto emissions reduction commitments. This paper reviews overall CDM activities and transportation CDM activities to date and then presents findings from three case studies of transportation CDM possibilities examined with the ASIF framework in Santiago de Chile. The analysis suggests that bus technology switch (I) provides a fairly good project fit for the CDM, while options aimed at inducing mode share (S) to bicycle, or modifying travel demand via land use changes (ASI) face considerable challenges. The implications of the findings for the CDM and the 'post-Kyoto' world are discussed

Future restrictions for sinks in the CDM. How about a cap on supply?

International Nuclear Information System (INIS)

Forner, C.; Jotzo, F.

2002-01-01

The first commitment period of the Kyoto Protocol is expected to result in only a small role for the Clean Development Mechanism (CDM), including afforestation and reforestation projects. Wide ranging concerns regarding sinks in the CDM have been reflected in the Marrakech Accords capping the total amount of emission offsets from sinks projects to be used by Annex I countries. Decisions about the second commitment period and beyond are likely to be of far greater importance for these projects. This paper contributes to the discussion on how caps on sinks under the CDM could be used to obtain overall improved outcomes for developing countries. We examine two distinctive ways in which quantitative caps on sinks in the CDM can be implemented: one, restricting the use of sinks CERs to meet targets, as under the Marrakech Accords (a cap on demand); and two, restricting supply of sink CERs using a quota system. We argue in favour of a supply side cap, if Parties are to preserve the idea of limiting sinks in the CDM. Limiting the supply of credits could lead to better financial outcomes for developing countries as a whole, make higher-cost projects viable which may have better sustainability impacts, and provide an alternative to deal with equity concerns between developing countries

2014-05-01

Full Text Available One of the responses to the threat of global warming is the Kyoto Protocol and the associated Clean Development Mechanism (CDM to reduce greenhouse gases. South Africa is an ideal country for the implementation of industrial CDM projects, yet lags behind many other countries. This qualitative research determines the factors that cause South Africa to lag other developing countries in the implementation of industrial CDM projects and the interventions that will have the most impact on accelerating implementation. The research involved interviews with 30 experts involved in the South African CDM process. The results identify the factors perceived to be facilitating and inhibiting the use of CDM opportunities and a framework for CDM practitioners to develop an implementation strategy within South African industry is established.

Study was made on promotion of CDM (clean development mechanism) project through technology transfer with plant exports. Although CDM system was provided in COP3 on climate change held in Kyoto in 1997, its detailed rules including project approval are yet undecided, and only the schedule to provide the detailed rules until COP6 in 2000 was decided in COP4 in 1998. The common recognition that the CDM project with plant exports produces various merits for both Japan and the partner country is increasing. However, from the viewpoint of forming concrete CDM projects, most Japanese enterprises are passive in approach to the CDM project because of no detailed design of CDM, uncertain profitability and procedures, and avoidance of additional burdens. Plant export is also difficult because of the fact that assessment of a new project is difficult. Enterprises' deeper recognition on the CDM project, and a governmental integrated support system are desirable. (NEDO)

Wind farm investment risks under uncertain CDM benefit in China

2010-01-01

China has set an ambitious target to increase its wind power capacity by 35 GW from 2007 to 2020. The country's hunger for clean power provides great opportunities for wind energy investors. However, risks from China's uncertain electricity market regulation and an uncertain energy policy framework, mainly due to uncertain Clean Development Mechanism (CDM) benefits, prevent foreign investors from investing in China's wind energy. The objectives of this paper are to: (1) quantify wind energy investment risk premiums in an uncertain international energy policy context and (2) evaluate the impact of uncertain CDM benefits on the net present values of wind power projects. With four scenarios, this study simulates possible prices of certified emissions reductions (CERs) from wind power projects. Project net present values (NPVs) have been calculated. The project risk premiums are drawn from different and uncertain CER prices. Our key findings show that uncertain CDM benefits will significantly affect the project NPVs. This paper concludes that the Chinese government needs revising its tariff incentives, most likely by introducing fixed feed-in tariffs (FITs), and re-examining its CDM-granting policy and its wind project tax rates, to facilitate wind power development and enable China to achieve its wind energy target.

The Clean Development Mechanism as a Vehicle for Technology Transfer and Sustainable Development - Myth or Reality?

Directory of Open Access Journals (Sweden)

Gary Cox

2010-09-01

Full Text Available This paper critically examines the clean development mechanism (CDM established under Article 12 of the Kyoto Protocol in terms of its effectiveness as a vehicle for technology transfer to developing countries, a specific commitment under the UNFCCC. Fundamentally, the paper poses the question of whether technology transfer as part of the CDM is a myth or a reality in the broader context of sustainable development. Technology transfer between countries of the North and South is explored in a historical context and the emergence of technology transfer obligations is traced in multilateral environmental agreements. The architecture of the UNFCCC and the Kyoto Protocol are examined in relation to technology transfer obligations. Empirical studies are reviewed to gain an understanding of how CDM operates in practice, with a closer examination of a small number of recent CDM projects. There is an update on the Technology Mechanism being established under the Copenhagen Accord. The paper concludes with a summary of the benefits of CDM to date and its current limitations in achieving the scaling-up of affordable environmentally sound technology transfer envisaged in the Bali Action Plan. The conclusion is that technology transfer must be a much more explicit objective of CDM with better targeting of projects in order to achieve locally sustainable equitable outcomes. Furthermore, the link between CDM and technology transfer needs to be much more explicitly made in order that, in the long run, such interventions will lead to viable low emission development pathways in developing countries.

Analysis of the partnership network in the clean development mechanism

International Nuclear Information System (INIS)

Kang, Moon Jung; Park, Jihyoun

2013-01-01

The clean development mechanism (CDM) is a global collaborative action proposed at the Kyoto Protocol in response to climate change issues. The CDM contributes to cost-efficient reduction of greenhouse gas emissions in industrialized countries and promotes sustainable development in developing countries. Its fundamental framework is based on partnerships between industrialized and developing countries. This study employs social network analysis to investigate the dynamics of the partnership networks observed in 3816 CDM projects registered in the database of the United Nations Framework Convention on Climate Change over the period of 2005 to 2011. Our three main findings can be summarized as follows. First, the CDM partnership network is a small world; however, its density tends to decrease as the number of participants for a CDM project decreases. Second, the partnership networks’ leading groups tend to shift from partner countries into host countries. Third, a host country that pursues more partnership-based projects takes better control of resources and knowledge-flow in the ego-network formed around that country, and can thus better utilize global resources for its CDM projects. - Highlights: ► We investigate dynamics of the international partnership networks of CDM projects. ► The density of CDM networks tends to decrease by time. ► The partnership networks’ leading groups tend to shift into host countries. ► A host country with more partnerships better utilizes global knowledge resources.

Toward an effective implementation of clean development mechanism projects in China

With the already huge and growing amount of greenhouse gas emissions and a great deal of low-cost abatement options available, China is widely expected as the world's number one host country of clean development mechanism (CDM) projects. But, making this potential a reality represents a significant challenge for China, because there has been a general lack of awareness by both the Chinese government and business communities, clear institutional structure, and implementation strategy. This has raised great concern about China's ability to compete internationally for CDM projects and exploit fully its CDM potential. This paper aims to address how CDM projects will be effectively implemented in China by examining the major CDM capacity building projects in China with bilateral and multilateral donors, the treatment of low-cost, non-priority CDM projects, and how a system for application, approval, and implementation of CDM projects is set up in China and what roles the main institutional actors are going to play in the system. We conclude that these capacity building assistances, the establishment of streamlined and transparent CDM procedures and sound governance, and the lessons learned and experience gained from the implementation of the CDM project in Inner Mongolia and the two Prototype Carbon Fund' projects will help China to take advantage of CDM opportunities. Moreover, in order to further capitalize on its CDM potential, there is a pressing need for the Chinese government to amend its current interim CDM regulations, in particular those controversial provisions on the eligibility to participate in CDM projects in China and the distribution of the revenues derived from CDM project between the project developer and the Chinese government. We believe that taking these capacity building projects and the recommended actions to clearly define the sustainable development objective of the CDM and disseminate CDM knowledge to local authorities and project developers as

Climate change is a serious concern worldwide. Policy research on climate change in the past decades has largely focused on applied modelling exercises. However, the implications of specific policy strategies such as the clean development mechanism (CDM) for global and regional economic and environmental developments has received relatively little attention. This is partly caused by the complexities of modelling an instrument like CDM. By using and modifying the GTAP-E modelling system (GTAP stands for Global Trade Analysis Project), this paper sets out to trace the combined economic and environmental impacts of CDM policies. Particular emphasis is placed on technology transfer induced by alternative CDM policies. Specific attention is devoted to the possible negative consequences of non-participation of the USA in the global coalition, and the associated distributional impacts world-wide.

How to make the clean development mechanism sustainable-The potential of rent extraction

International Nuclear Information System (INIS)

Muller, Adrian

2007-01-01

The clean development mechanism (CDM) should foster sustainable development and greenhouse gas emission reductions. The design of the CDM and first experience suggest that it may not achieve these goals. Developing countries hosting CDM projects may lose cheap emission reduction possibilities for their own future use, and sustainable development and technology transfer may not take place. On the other hand, the CDM has the potential to generate considerable rents if permit prices are high or costs low. To account for equity and distributional issues, a deliberate decision on how to distribute these rents could be taken and the potential failure of the CDM in meeting its goals calls for some further regulation. I suggest to combine these two issues and to extract the rents by a profit tax. Ideally, the tax revenues could contribute to national sustainable development strategies, to offset external costs imposed by CDM projects and to extract part of the resource rent they may generate. The international character of the CDM could offer a frame for internationally coordinated tax design. This would hedge against a potential race to the bottom

Under European Union proposals for CO 2 emission reduction between 2013 and 2020, a Member State can transfer to another Member State the right to use its unused Clean Development Mechanism ('CDM') credits. The paper addresses three issues in relation to these CDM Warrants ('CDM W '). First, how should the Member State treat the CDM W in making decisions concerning emission reduction? The price of the property right is an important signal for a Member State in deciding the level of domestic abatement compared to trading in CDM W s. In other words, a shadow price for CDM W s should be used in formulating the emission strategy in order to determine whether or not a Member State is a buyer or seller of CDM W s. Second, what mechanism should be used to facilitate the exchange of CDM W s? The preferred mechanism depends on the market size, over which there appears to be some ambiguity: market intermediaries such as Over-the-Counter trades and exchanges are preferred if market size is small; auctions if the market size is large. Third, who should realise the value of CDM W s-the State, existing polluters, etc.? The value of CDM W s should accrue to the State. - Research highlights: →Clean Development Mechanism Warrants (CDMw) reduce the costs of emission reduction. →Member States should explicitly take into account the value of the CDM w s. →Appropriate market mechanisms - exchanges or auctions - should be created. →The value of CDM w s should accrue to government.

Highlights: Black-Right-Pointing-Pointer This is a compendium on GHG reductions via improved waste strategies in Africa. Black-Right-Pointing-Pointer This note provides a strategic framework for Local Authorities in Africa. Black-Right-Pointing-Pointer Assists LAs to select Zero Waste scenarios and achieve sustained GHG reduction. - Abstract: Only few Clean Development Mechanism (CDM) projects (traditionally focussed on landfill gas combustion) have been registered in Africa if compared to similar developing countries. The waste hierarchy adopted by many African countries clearly shows that waste recycling and composting projects are generally the most sustainable. This paper undertakes a sustainability assessment for practical waste treatment and disposal scenarios for Africa and makes recommendations for consideration. The appraisal in this paper demonstrates that mechanical biological treatment of waste becomes more financially attractive if established through the CDM process. Waste will continue to be dumped in Africa with increasing greenhouse gas emissions produced, unless industrialised countries (Annex 1) fund carbon emission reduction schemes through a replacement to the Kyoto Protocol. Such a replacement should calculate all of the direct and indirect carbon emission savings and seek to promote public-private partnerships through a concerted support of the informal sector.

Explaining the differential distribution of Clean Development Mechanism projects across host countries

The Clean Development Mechanism (CDM) of the Kyoto Protocol represents an opportunity to involve all developing countries in the effort to reduce greenhouse gas emissions while also promoting sustainable development. To date, however, the majority of CDM projects have gone to emerging markets such as China, India, Brazil, and Mexico, while very few least developed countries have hosted projects. This paper investigates the differential distribution of CDM activities across countries. We develop a conceptual model for project profitability, which helps to identify potential country-level determinants of CDM activity. These potential determinants are employed as explanatory variables in regression analysis to explain the actual distribution of projects. Human capital and greenhouse gas emission levels influenced which countries have hosted projects and the amount of certified emission reductions (CER) created. Countries that offered growing markets for CDM co-products, such as electricity, were more likely to be CDM hosts, while economies with higher carbon intensity levels had greater CER production. These findings work against the least developed countries and help to explain their lack of CDM activity. - Research Highlights: → Regression models are used to explain the inter-country distribution of CDM projects. → Emissions and human capital are significant for hosting projects and CER creation. → An economy's emissions intensity is significant in determining CERs created. → Capacity building and electricity sector growth are significant in hosting projects. → The experience level for host countries in the CDM is significant for CER creation.

Net climate change mitigation of the Clean Development Mechanism

The Clean Development Mechanism (CDM) has allowed industrialized countries to buy credits from developing countries for the purpose of meeting targets under the Kyoto Protocol. In principle, the CDM simply shifts the location of emission reductions, with no net mitigation impact. Departing from this zero-sum calculus, the Cancun Agreements reached at the sixteenth session of the Conference of the Parties (COP) in 2010 called for “one or more market-based mechanisms” capable of “ensuring a net decrease and/or avoidance of global greenhouse gas emissions”, an intention reiterated at COP 17 and COP 18. This article explores the extent to which the CDM may or may not already lead to such a “net decrease.” It finds that the CDM's net mitigation impact likely hinges on the additionality of large-scale power projects, which are expected to generate the majority of CDM credits going forward. If these projects are truly additional and continue to operate well beyond the credit issuance period, they will decrease global greenhouse gas emissions. However, if they are mostly non-additional, as research suggests, they could increase global greenhouse gas emissions. The article closes with a discussion of possible means to increase mitigation benefit. - Highlights: • The CDM's method for assessing additionality remains controversial and contested. • We develop two scenarios of the net emissions impact of the CDM. • The integrity of the CDM hinges on the emissions impact of power supply projects. • Additionality is hard to demonstrate with confidence for most power-supply projects. • A number of options are available to increase the mitigation benefit of the CDM

The papers, which are all written from an African perspective, are an important contribution to the debate surrounding the relevance and applicability of the Clean Development Mechanism in Africa. In addition to sector-specific discussions on the prospects for CDM in the energy, transport, industry and forestry sectors, various authors have attempted to tackle complex issues related to the instituional design of CDM, its mode of operation, participatory implementation and methodological questions such as baselines and additionality.

Xie, Huiming; Shen, Manhong; Wang, Rui

2014-01-01

As regards the dual goals of additionality and sustainability, some clean development mechanism (CDM) projects were successfully registered while some were rejected by the Executive Board (EB). This paper focuses on two final statuses of these projects and aims to explore the potential determinants of CDM activities. Based on the Chinese samples of the rejections and registrations, we find that (1) according to the financial barrier analysis with the internal rate of return without CDM, the additionality is the most important and robust rule of CDM activities and the CDM projects successfully registered are more additional than the rejected ones in China; (2) the sustainability is another important determinant of CDM activities in China and Chinese CDM activities are sustainable in terms of size, while the EB is criticized for its selection of unsustainable CDM projects in terms of cost-effectiveness on emission reductions within a long period or in terms of hydropower plants; (3) some other factors including the prices of sale electricity and certified emission reductions, the generating capacity and installed capacity all tend to pose significant impacts on the final status of each project that features the CDM activities in local areas of China. - Highlights: • The final status of each project features the CDM activities in local areas. • Microeconomic factors have significant impacts on the final statuses. • The additionality is the most important and robust rule of CDM activities in China. • Chinese CDM activities are sustainable in terms of size. • Chinese unsustainable CDM projects were selected by the EB in terms of cost-effectiveness

Transaction costs of unilateral CDM projects in India-results from an empirical survey

Krey, Matthias

2005-01-01

Recently, transaction costs in the context of the Clean Development Mechanism (CDM) gained considerable attention as they were generally perceived to be significantly higher than for the other Kyoto Mechanisms. However, empirical evidence on the amount of transaction costs of CDM projects is very scarce. This paper presents the results from an empirical survey designed to quantify transaction costs of potential non-sink CDM projects in India. The definition of transaction costs of CDM projects was derived from recent literature and observations made in the current market for Certified Emission Reductions (CERs). During the survey, parts of transaction costs of 15 projects were quantified. An assessment of the results showed that specific transaction costs depend, to a large extent, on economies of scale in terms of total amount of CERs generated over the crediting period. Total transaction costs were quantified for seven projects. The costs range from 0.07 to 0.47 dollar/t CO 2 . As the projects have an emission reduction between 0.24 Mt CO 2 and 5.00 Mt CO 2 over the crediting period, the results support the assumption of Michaelowa et al. (Climate Policy 3 (2003) 273) that projects with emission reductions smaller than 0.20 Mt CO 2 are not economically viable at current CER prices

Sustainable development benefits of clean development mechanism projects

The clean development mechanism (CDM) is part of the global carbon market developing rapidly in response to global warming. It has the twin objective to achieve sustainable development (SD) in host countries and assist Annex-1 countries in achieving their emission reduction targets in a cost-efficient manner. However, research has shown that trade-offs between the two objectives exist in favour of cost-efficient emission reductions and that left to the market forces, the CDM does not significantly contribute to sustainable development. The main argument of the paper is the need for an international standard for sustainability assessment-additional to national definitions-to counter weaknesses in the existing system of sustainability approval by designated national authorities in host countries. The article develops a new methodology, i.e. a taxonomy for sustainability assessment based on text analysis of the 744 project design documents (PDDs) submitted for validation by 3 May 2006. Through analysis of the SD benefits of all CDM projects at aggregated levels, the strengths and limitations of the taxonomy are explored. The main policy implication of the research is to propose the taxonomy as the basis of an international verification protocol for designated operational entities (DOEs) for reporting, monitoring and verifying that potential SD benefits described in the PDDs are actually realized

An agreement on CDM rules is important both for industrialized and developing countries. As a flexibility mechanism, it will allow industrialized countries to benefit from low cost emission reductions but the CDM, as a main goal, should also stimulate a more sustainable economic development in DCs. The CDM is the sole instrument, with GEF, proposed for DCs participation into climate change prevention. This situation satisfies a majority of DCs, but CDM may not offer sufficient perspectives for some countries with rapid industrialization given the huge economic stakes linked to the creation of a carbon credits market between Annex I countries. The operationality of the CDM is not yet established and important questions, as environmental additionality, are still unresolved. Here we first examine the rules in order to validate project additionality and their possible consequences on the effectiveness and the scope of the mechanism. The different reactions of major DCs groups on the structure of the mechanism will then be analysed. This will lead us to examine the possibilities to enlarge participation of DCs in climate change prevention according to the apparent wish of semi-industrialized countries. (author)

The report describes the background for the international co-operation on reducing the greenhouse gases and the background for the instruments. How the instruments work in theory and what the practical problems may be. What agents' incentives are when they engage in JI or CDM, and how the initiation of the instruments can be organised. The institutional frameworks for JI, CDM and TP are discussed. The report describes how the Kyoto instruments and the Kyoto commitments interact with other instruments and describe distributive effects between countries. It is analysed how the use of CDM may influence the developing countries incentives to participate in the coalition of committed countries. In the concluding chapter some recommendations on the use of JI, TP and CDM are given. The recommendations are a kind of dialog with especially the Norwegian and Swedish reports on tradable permits.

Addressing carbon Offsetters’ Paradox: Lessons from Chinese wind CDM

International Nuclear Information System (INIS)

He, Gang; Morse, Richard

2013-01-01

The clean development mechanism (CDM) has been a leading international carbon market and a driving force for sustainable development. But the eruption of controversy over offsets from Chinese wind power in 2009 exposed cracks at the core of how carbon credits are verified in the developing economies. The Chinese wind controversy therefore has direct implications for the design and negotiation of any successor to the Kyoto Protocol or future market-based carbon regimes. In order for carbon markets to avoid controversy and function effectively, the lessons from the Chinese wind controversy should be used to implement key reforms in current and future carbon policy design. The paper examines the application of additionality in the Chinese wind power market and draws implications for the design of effective global carbon offset policy. It demonstrates the causes of the wind power controversy, highlights underlying structural flaws, in how additionality is applied in China, the Offsetters' Paradox, and charts a reform path that can strengthen the credibility of global carbon markets. - Highlights: • We investigated 143 Chinese wind CDM projects by the eruption of the additionality controversy. • We examined the application of additionality in the Chinese wind power market. • We drew implications for the design of effective global carbon offset policy. • The underlying structural flaws of CDM, the Offsetters′ Paradox, was discussed. • We charted a reform path that can strengthen the credibility of global carbon markets

There are continuous debates around the question of whether CDM really contributes to sustainable development (SD) in host countries. Employment impact is an essential indicator of SD. Based on an input-out approach this research builds a quantitative assessment model to evaluate the employment impacts of CDM. Both direct and indirect jobs creation and job losses of CDM projects in the power sector registered by the end of 2011 are calculated by project types and power grids where the project is located. Results of this study show that, although the above mentioned CDM projects causes about 99,000 net direct job losses, they also create about 3.08 million indirect jobs, resulting in the gross employment of CDM to be about 2.98 million. Thereof, hydro projects induce both direct and indirect job losses, which comes to approximately 0.89 million. Solar projects have the most potential since they own the highest indirect jobs created by one GWh generation, about 104 jobs/GWh. - Highlights: • An input–output model was built for assessment of CDM projects' employment impact; • CDM projects create direct and indirect jobs while cause some losses in short. • Significant indirect job gains of CDM projects were found; • Solar projects cause 104 jobs/GWh in average, ranking as the highest contributor

This study analyses whether Germany should use the flexible mechanisms under the Kyoto protocol or whether it should continue to achieve its greenhouse gas reduction targets by dint of domestic policies and measures. It estimates the future potential of the project-based Kyoto mechanisms (CDM and JI) and the impacts of its use on the German and the global economy, using an integrated-assessment model. In a Delphi survey, the expectations of international experts on the future prospects of the project-based Kyoto mechanisms are assessed. The study finishes with an analysis of options for promoting the use of the flexible mechanisms in Germany and concludes that the Federal Government of Germany should establish a project-based mechanisms fund of 25 to 50 million Kyoto units to cover the compliance uncertainties due to unexpected temperature or business cycle variations. (orig.) [German] Diese Studie untersucht, ob Deutschland die flexiblen Mechanismen unter dem Kyoto-Protokoll nutzen sollte oder weiterhin seine Treibhausgasreduktionsziele durch inlaendische Politiken und Massnahmen erreichen sollte.

In einer Delphi-Befragung werden die Erwartungen internationaler Experten in Hinblick auf die kuenftigen Perspektiven der projektbezogenen Kyoto- Mechanismen ermittelt. Abschliessend werden Moeglichkeiten zur Foerderung der Nutzung der flexiblen Mechanismen in Deutschland analysiert, mit der Schlussfolgerung, dass die Bundesregierung einen 25 bis 50 Millionen Kyoto-Einheiten umfassenden Fonds fuer projektbezogene Mechanismen einrichten sollte, um die Unsicherheiten bei der Erfuellung des Kyoto-Ziels infolge unerwarteter Temperaturschwankungen oder einer Aenderung der Konjunkturentwicklung abzudecken.

The most influential factor in developing a magnet design and the manufacturing processing capable of mass producing Collider Dipole Magnets (CDMs) for the Superconducting Super Collider (SSC) is the work system or organization design. It is essential that design of the organization balances the demanding quality, schedule and cost aspects of the SSC program with the extraordinary technological challenges of the CDMs. The organization approach taken by the General Dynamics team is based on high employee involvement. This approach entails more widely distributed access to information, coordination and control of work, decision-making and rewards for overall performance. Implementation of this approach will apply team-based organizational concepts and proven methodologies such as concurrent engineering, work teams, skill-based pay and gainsharing. This paper focuses on the structural facets of the General Dynamics organization design to accomplish the CDM Program. Why this management approach is being taken, how it was developed and tuned for the CDM Program and how it will be incorporated in personnel staffing is described in this paper along with general operational characteristics. The issues of pay and gainsharing, while recognized as vital constituents of the overall design and effectiveness, are not discussed in this paper

CDM criticisms: don't throw the baby out with the bathwater

CDM has delivered greater offset volumes than anticipated, mainly with money from the private sector in host countries (underlying project investment) and investor countries (carbon offset purchasing) and has built considerable institutional capacity. Criticisms have focused on high transaction costs and lack of scalability; additionality challenges and lack of net mitigation impact; preventing more ambitious targets and changes in emissions paths in developed and developing countries alike; excessive rents and perverse incentives; unbalanced regional distribution; low local sustainable development benefits; corruption and lack of transparency; and lack of technology transfer. While some of these criticisms are justified, others are outdated. Transaction costs have been drastically reduced. Excessive rents and perverse incentives in the CDM will be substantially reduced post-2012. Unbalanced regional distribution will be reduced by new rules; moreover, this is probably less of a problem than commonly thought. Some criticisms are erroneously founded. There is no evidence of CDM preventing more ambitious targets in developing countries while it could prevent changes in emissions paths in developed countries. Few CDM projects have serious known problems as regards sustainable development. Corruption and fraud seem limited; and technology transfer has never been a core CDM concern. Ironically, critics often neglect the elements that need to be improved. To ensure additionality, CDM rules must be tightened to exclude common practice projects and prevent host countries from changing their policies to cater for CDM projects. CDM's scalability and additionality challenges could be substantially reduced by discounting emission reductions. There could still be some non-additional projects, but the volume of the overall portfolio of projects would be additional.(Author)

Technology transfer in the Clean Development Mechanism

Technology transfer is often mentioned as an ancillary benefit of the Kyoto Protocol's Clean Development Mechanism (CDM), but this claim has never been researched or substantiated. The question of technology transfer is important from two perspectives: for host countries, whether the CDM provides a corridor for foreign, climate-friendly technologies and investment, and for industrialised countries as it provides export potential for climate-friendly technologies developed as a consequence of stringent greenhouse gas targets. In order to better understand whether technology transfer from the EU and elsewhere is occurring through the CDM, and what is the value of the associated foreign investment, this paper examines technology transfer in the 63 CDM projects that were registered on January 1st, 2006. Technology originates from outside the host country in almost 50% of the evaluated projects. In the projects in which the technology originates from outside the host country, 80% use technology from the European Union. Technologies used in non-CO2 greenhouse gas and wind energy projects, and a substantial share of the hydropower projects, use technology from outside the host country, but biogas, agricultural and biomass projects mainly use local technology. The associated investment value with the CDM projects that transferred technology is estimated to be around 470 million Euros, with about 390 coming from the EU. As the non-CO2 greenhouse gas projects had very low capital costs, the investment value was mostly in the more capital-intensive wind energy and hydropower projects

Extracting the resource rent from the CDM projects: Can the Chinese Government do better?

The revenue generated from a CDM project in China will be shared by the government and the project owner, and is also subject to the corporate income tax. This paper studies the impacts of the revenue sharing policy and income tax on the CDM market. The economic model presented in this paper shows that higher-cost CDM projects will be more affected by the CDM policies than lower-cost projects. In addition, the majority of CERs will be generated from lower-cost projects. This kind of distribution of CERs across different types of CDM projects, which is in line with the current picture of the CDM market in China, is not consistent with the goal of sustainable development. A simulation shows that a type-by-type tax/fee scheme would be more effective in assisting sustainable development than the current CDM policies. The study also suggests the government use negative tax/fee with the type-by-type scheme to subsidize the CDM projects that generate large sustainability benefits but would otherwise not be developed due to high costs. If all of the revenue from the CDM is recycled, it is estimated that CERs generation will increase by 98.28 MtC, mainly from the CDM projects that have substantial sustainability benefits for the host country.

Corporate motives and strategies of both investing and hosting country affect the outcomes of a clean development mechanism (CDM) project-who introduces what technology to whom-and result in large differences in economic viability and the CO 2 emission reductions. This is particularly true for steel industry in which steel making consists of many detailed and complex processes, a given strategy could produce cumulative effects of the individual technologies used, leading to large energy savings overall. The objective of this study is to demonstrate some analytical methods that can be used to quantitatively evaluate the impacts of technology selection on the profit performance of CDM projects. Specifically, in this study we analyze a CDM project to introduce energy saving technology from Japan to a small steel manufacturer in China's Shandong Province, and conduct a simulation of the quantitative relationships between various technology options and profitability. Based on these results, we examine the environmental and economic significance of technology selection for CDM projects. To take this further, we then reconsider the profitability of a project as typical FDI activity (i.e., without the CDM), and by comparing this outcome with the CDM case, we clarify the significance and potential of the CDM

Co-benefits of including CCS projects in the CDM in India's power sector

This study examines the effects of the inclusion of the co-benefits on the potential installed capacity of carbon dioxide capture and storage (CCS) projects with a linear programming model by the clean development mechanism (CDM) in India's power sector. It is investigated how different marginal damage costs of air pollutants affect the potential installed capacity of CCS projects in the CDM with a scenario analysis. Three results are found from this analysis. First, large quantity of IGCC with CCS becomes realizable when the certified emission reduction (CER) prices are above US$56/tCO 2 in the integrated Northern, Eastern, Western, and North-Eastern regional grids (NEWNE) and above US $49/tCO 2 in the Southern grid. Second, including co-benefits contributes to decrease CO 2 emissions and air pollutants with introduction of IGCC with CCS in the CDM at lower CER prices. Third, the effects of the co-benefits are limited in the case of CCS because CCS reduces larger amount of CO 2 emissions than that of air pollutants. Total marginal damage costs of air pollutants of US$250/t and US$200/t lead to CER prices of US$1/tCO 2 reduction in the NEWNE grid and the Southern grid. - Highlights: • We estimate effects of co-benefits on installed capacity of CCS projects in the CDM. • We develop a linear programming (LP) model of two grids of India. • Including co-benefits contributes to introduce IGCC with CCS in the CDM at lower CER prices

Small-scale CDM projects in a competitive electricity industry: How good is a simplified baseline methodology?

2007-01-01

Setting baseline emissions is one of the principal tasks involved in awarding credits for greenhouse gas emission (GHG) mitigation projects under the Clean Development Mechanism (CDM). An emission baseline has to be project-specific in order to be accurate. However, project-specific baseline calculations are subject to high transaction costs, which disadvantage small-scale projects. For this reason, the CDM-Executive Board (CDM-EB) has approved simplified baseline methodologies for selected small-scale CDM project categories. While the simplified methods help reduce the transaction cost, they may also result in inaccuracies in the estimation of emission reductions from CDM projects. The purpose of this paper is to present a rigorous economic scheduling method for calculating the GHG emission reduction in a hypothetical competitive electricity industry due to the operation of a renewable energy-based power plant under CDM and compare the GHG emission reduction derived from the rigorous method with that obtained from the use of a simplified (i.e., standardized) method approved by the CDM-EB. A key finding of the paper is that depending upon the level of power demand, prices of electricity and input fuels, the simplified method can lead to either significant overestimation or substantial underestimation of emission reduction due to the operation of renewable energy-based power projects in a competitive electricity industry

The Bonn agreement reached in July at the sixth conference of the parties (COP) to the FCCC states 'that for the first commitment period, the total of additions to and subtractions from the assigned amount of a party resulting from eligible LULUCF activities under Article 12 (i.e. CDM), shall not exceed 1% of base-year emissions of that party, times five'. The most probable size of this LULUCF-CDM (land use, land-use change and forestry - clean development mechanism) market is analyzed in light of each Annex I party's actual and projected emissions and policies. Results show that the market size would be only about 110 Mt CO2 eq. for 2000-2012, representing a maximum global market value of about US$ 876 million

A method of predicting the reliability of CDM coil insulation

Kytasty, A.; Ogle, C.; Arrendale, H.

1992-01-01

This paper presents a method of predicting the reliability of the Collider Dipole Magnet (CDM) coil insulation design. The method proposes a probabilistic treatment of electrical test data, stress analysis, material properties variability and loading uncertainties to give the reliability estimate. The approach taken to predict reliability of design related failure modes of the CDM is to form analytical models of the various possible failure modes and their related mechanisms or causes, and then statistically assess the contributions of the various contributing variables. The probability of the failure mode occurring is interpreted as the number of times one would expect certain extreme situations to combine and randomly occur. One of the more complex failure modes of the CDM will be used to illustrate this methodology

In a companion paper [Dechezlepretre, A., Glachant, M., Meniere, Y., 2008. The Clean Development Mechanism and the international diffusion of technologies: An empirical study, Energy Policy 36, 1273-1283], we gave a general description of technology transfers by Clean Development Mechanism (CDM) projects and we analyzed their drivers. In this paper, we use the same data and similar econometric models to explain inter-country differences. We focus on 4 countries gathering about 75% of the CDM projects: Brazil, China, India and Mexico. Sixty eight percent of Mexican projects include an international transfer of technology. The rates are, respectively, 12%, 40% and 59% for India, Brazil and China. Our results show that transfers to Mexico and Brazil are mainly related to the strong involvement of foreign partners and good technological capabilities. Besides a relative advantage with respect to these factors, the higher rate of international transfers in Mexico seems to be due to a sector-composition effect. The involvement of foreign partners is less frequent in India and China, where investment opportunities generated by fast growing economies seem to play a more important role in facilitating international technology transfers through the CDM. International transfers are also related to strong technology capabilities in China. In contrast, the lower rate of international transfer (12%) in India may be due to a better capability to diffuse domestic technologies

Host country attractiveness for CDM non-sink projects

International Nuclear Information System (INIS)

Jung, Martina

2006-01-01

In the present study, CDM host countries are classified according to their attractiveness for CDM non-sink projects by using cluster analysis. The attractiveness of host countries for CDM non-sink projects is described by three indicators: mitigation potential, institutional CDM capacity and general investment climate. The results suggest that only a small proportion of potential host countries will attract most of the CDM investment. The CDM (non-sink) stars are China, India, Brazil, Argentina, Mexico, South Africa, Indonesia and Thailand. They are followed by attractive countries like Costa Rica, Trinidad and Tobago, Mongolia, Panama, and Chile. While most of the promising CDM host countries are located in Latin America and Asia, the general attractiveness of African host countries is relatively low (with the exception of South Africa). Policy implications of this rather inequitable geographical distribution of CDM project activities are discussed briefly

Review of monitoring uncertainty requirements in the CDM

International Nuclear Information System (INIS)

Shishlov, Igor; Bellassen, Valentin

In order to ensure the environmental integrity of carbon offset projects, emission reductions certified under the Clean Development Mechanism (CDM) have to be 'real, measurable and additional', which is ensured through the monitoring, reporting and verification (MRV) process. MRV, however, comes at a cost that ranges from several cents to EUR1.20 and above per ton of CO 2 e depending on the project type. This article analyzes monitoring uncertainty requirements for carbon offset projects with a particular focus on the trade-off between monitoring stringency and cost. To this end, we review existing literature, scrutinize both overarching monitoring guidelines and the 10 most-used methodologies, and finally we analyze four case studies. We find that there is indeed a natural trade-off between the stringency and the cost of monitoring, which if not addressed properly may become a major barrier for the implementation of offset projects in some sectors. We demonstrate that this trade-off has not been systematically addressed in the overarching CDM guidelines and that there are only limited incentives to reduce monitoring uncertainty. Some methodologies and calculation tools as well as some other offset standards, however, do incorporate provisions for a trade-off between monitoring costs and stringency. These provisions may take the form of discounting emissions reductions based on the level of monitoring uncertainty - or more implicitly through allowing a project developer to choose between monitoring a given parameter and using a conservative default value. Our findings support the introduction of an uncertainty standard under the CDM for more comprehensive, yet cost-efficient, accounting for monitoring uncertainty in carbon offset projects. (authors)

2013-01-01

This study aims to investigate the barriers which impede the promotion of Energy Efficient Building (EEB), and to propose solutions to alleviate these barriers by capturing the benefits from Clean Development Mechanism (CDM), in the context of China. Through comprehensive literature review, eight types of significant barriers are identified, including weak enforcement of government policies, market inefficiency, information barrier, small and scattering buildings, fragmentation of the construction industry, perceived high risk, higher initial cost, and difficulty in energy management. To overcome the barriers, the potential of CDM to facilitate EEB promotion is then discussed. These barriers are verified and potential solutions are tested with a questionnaire survey conducted among five professional groups in China, i.e. designers, project managers, quantity surveyors, marketing managers and property managers. The results suggest that they generally identified with the barriers. However, their limited awareness of CDM implies that corresponding policies should be formulated and implemented to improve their capability of providing more EEBs with CDM. - Highlights: ► Eight types of significant barriers to the implement of EEB are identified. ► The sources and roots of barriers are verified with the industry professionals. ► Benefits of CDM to EEB are discussed. ► There is limited awareness of CDM in building sector. ► Overcoming or alleviating these barriers through CDM and other sources are proposed

The third conference (COP3) of the United Nations Framework Convention on Climate Change held in December 1997 in Kyoto has adopted the Kyoto mechanisms (the 'discharge right transaction', the 'joint implementation (JI)' among advanced countries, and the 'clean development mechanism (CDM)' applied to developing countries). The Kyoto mechanisms are intended to provide flexibility to the methods to achieve the greenhouse effect gas reduction targets established in the Kyoto Protocol. The Kyoto mechanisms are considered to be implemented even during the year 2000, whose details are scheduled to be decided at COP6. Since the advanced countries have established the targets for reduction of greenhouse effect gas emission, governments and research institutes are taking various approaches. In addition, since the targets for reduction of greenhouse effect gas emission have been established, discussions are indispensable on methodology to establish the quantity of discharge and absorption of greenhouse effect gases (the so-called base line) when no project exists, as required to calculate the discharge reduction quantity as a result of implementing the project. The present survey has held study meetings attended by learned people, and compiled the results of the discussions. (NEDO)

Principle-Based Ethics and the Clean Development Mechanism

International Nuclear Information System (INIS)

Bay, Ingrid; Oughton, Deborah

2003-01-01

Search for common values can go a long way resolving international political and social differences, and represents an area where ethical evaluation can offer an input to international legislation. This paper argues that a principle-based, normative approach should be applied to evaluation of Clean Development Mechanism (CDM) projects and the goal of sustainable development (SD). Primafacie ethical principles to promote weil-being, dignity and justice can be defined and supported from international agreements on sustainable developments. To promote coherency, these principles should then be specifled according to particular CDM-projects, to produce a set of norms that covers: 1) the different dimension to sustainable development, 2) the distribution of costs and benefits across time and place, and 3) consequences for different affected parties, including future generations and the environment

Assessment of clean development mechanism potential of large-scale energy efficiency measures in heavy industries

Hayashi, Daisuke; Krey, Matthias

2007-01-01

This paper assesses clean development mechanism (CDM) potential of large-scale energy efficiency measures in selected heavy industries (iron and steel, cement, aluminium, pulp and paper, and ammonia) taking India and Brazil as examples of CDM project host countries. We have chosen two criteria for identification of the CDM potential of each energy efficiency measure: (i) emission reductions volume (in CO 2 e) that can be expected from the measure and (ii) likelihood of the measure passing the additionality test of the CDM Executive Board (EB) when submitted as a proposed CDM project activity. The paper shows that the CDM potential of large-scale energy efficiency measures strongly depends on the project-specific and country-specific context. In particular, technologies for the iron and steel industry (coke dry quenching (CDQ), top pressure recovery turbine (TRT), and basic oxygen furnace (BOF) gas recovery), the aluminium industry (point feeder prebake (PFPB) smelter), and the pulp and paper industry (continuous digester technology) offer promising CDM potential

It is purposed to promote the Activities Implemented Jointly (AIJ) and the clean development mechanism (CDM) intended of reducing carbon dioxide emission amount in China. Investigations have been performed on China's environment and energy problems, CDM assignments and transfer means, and project candidates. China emits a great amount of CO2 due to coal combustion, and the CO2 emission is anticipated to increase from the coal burning thermal power generation that may continue into the future. Countermeasures for the thermal power department as the object are required. Since 1997, China has been performing the AIJ project with Norway, Japan, and America, wherein such projects have been implemented with Japan as the dry coke fire extinguishing facility model project, the energy saving model project using alloy iron electric furnaces, and the model project to utilize effectively the refuse combustion waste heat. China is one of the countries in which the greenhouse effect gas emission reducing project can be performed at a minimum cost, who will be the important party in the CDM performed by the developed countries to achieve their obligation to reduce the greenhouse effect gas emission.

Full Text Available Objective – The main goal of this study is to identify and assess, within sustainability reports, information concerning potential carbon credits obtained through projects carried out under Clean Development Mechanism (CDM assumptions, as well as to assess CDM project experts’ perceptions of obstacles to entering carbon credit markets. Design/methodology/approach – exploratory, descriptive, bibliographical and documental research, and interviews. Theoretical basis - Research was based on the concepts of sustainability, especially as to environmental responsibility (CSR; cost-benefit analysis was also considered, since selling carbon credits can be a way of mitigating the trade off between immediate shareholder satisfaction and investment in CSR. Findings – The perceptions of representatives from carbon credit projects’ certifying companies was examined by means of a series of interviews – concluding that savings in costs, business marketing and certifications are even greater motivators than carbon credits themselves. We estimated that, through energy efficiency, the projects discussed in 2011 sustainability reports would be capable of saving approximately 538 million reais in costs. In addition, 40 million reais, considering the rate of the euro and of securities on December 31, 2014, would be gained through the sale of carbon credits. Practical implications – Thus, this research helps to demonstrate the significant potential for further financial gains that companies may obtain through energy efficiency and habitat restructuring, whether by taking advantage of CO2 reduction brought about by such projects, or by developing new projects that continue to benefit economy, society and the environment.

A quantitative analysis of the cost-effectiveness of project types in the CDM pipeline

Energy Technology Data Exchange (ETDEWEB)

Green, Gavin A.

2008-09-15

The flexibility of the CDM is intended to reduce the cost of compliance for Annex 1 countries and contribute to cost-effective reductions. This paper provides a framework for defining cost-effective payments for CDM carbon reductions. The projects in the CDM pipeline are categorised into project types. The data provided in the Project Design Documents is quantitatively assessed to calculate the median cost and range of costs for producing a CER from the project categories. These are measured against the range of prices in the market in order to estimate the level of cost-effectiveness. Global warming potential and size of the project were shown to be key factors in the cost of producing a CER. The results show that although prices for CERs are difficult to define in the primary CER market, many of the project categories generated CERs at a cost well below the lowest market price. The difference in these two values is defined as a loss in cost-effectiveness. The CDM is shown to be successful at developing the 'lowest hanging fruit' but the mechanism could be improved to fulfil the goal of cost-effectiveness by linking the price per CER to the cost of generating a CER.

Linking renewable energy CDM projects and TGC schemes: An analysis of different options

Del Rio, Pablo

2006-01-01

Renewable energy CDM (RE-CDM) projects encourage cost-effective GHG mitigation and enhanced sustainable development opportunities for the host countries. CERs from CDM projects include the value of the former benefits (i.e., 'climate change benefits'), whereas the second can be given value through the issuing and trading of tradable green certificates (TGCs). Countries could agree to trade these TGCs, leading to additional revenues for the investors in renewable energy projects and, therefore, further encouraging the deployment of CDM projects, currently facing significant barriers. However, the design of a combination of CDM projects and TGC schemes raises several conflicting issues and leads to trade-offs. This paper analyses these issues, identifies the alternatives that may exist to link TGC schemes with RE-CDM projects and analyses the impacts of those options on different variables and actors

Gao Weijun; Zhou Nan; Li Haifeng; Kammen, Daniel M

2007-01-01

China has become the world's second largest greenhouse gas (GHG) emitter behind the United States. It emits approximately three billion tons of CO 2 equivalents every year. Its growing economy and large population are making a wealthier, more consumption-oriented country. Energy demand is expected to grow 5-10% per year through 2030. Therefore, a large potential of GHG emission reduction in China can be expected. The clean development mechanism (CDM) put forward in the Kyoto Protocol for reductions of GHGs can support the sustainable development of developing countries and help developed countries to achieve their emission reduction targets at low cost. However, there are still many disagreements to be resolved between developing and developed countries. In this letter, we try to introduce the current development of CDM projects in China and discuss its potential and opportunities in the future decades

Barriers to clean development mechanism renewable energy projects in Mexico

International Nuclear Information System (INIS)

Lokey, Elizabeth

2009-01-01

Mexico is not reaching its full potential to capture benefits from clean development mechanism (CDM) projects because of its limited market for independent power producers (IPPs) and the barriers imposed on these entities by the state-run electric utility that controls most of the country's generation and transmission. This state-run entity has pursued CDM revenues only in isolated cases where international financial assistance was given because it is bound by law to pursue the least-cost generation option for its customers. Recent changes in Mexican legislation that provide incentives for renewable energy development could open the marketplace for these types of projects. (author)

The economics of the CDM levy: Revenue potential, tax incidence and distortionary effects

International Nuclear Information System (INIS)

Fankhauser, Samuel; Martin, Nat

2010-01-01

A levy on the Clean Development Mechanism and other carbon trading schemes is a potential source of finance for climate change adaptation. An adaptation levy of 2% is currently imposed on all CDM transactions which could raise around $500 million between now and 2012. This paper analyses the scope for raising further adaptation finance from the CDM, the economic costs (deadweight loss) of such a measure and the incidence of the levy, that is, the economic burden the levy would impose on the buyers and sellers of credits. We find that a levy of 2% could raise up to $2 billion a year in 2020 if there are no restrictions on demand. This could rise to $10 billion for a 10% tax. Restrictions on credit demand (called supplementarity limits, the requirement that most emission abatement should happen domestically) curtail trade volumes and consequently tax revenues. They also alter the economic impact of the CDM levy. Without supplementarity restrictions sellers (developing countries) bear two-thirds of the cost of the tax. If there are supplementarity limits they can pass on the tax burden to buyers (developed countries) more or less in full. Without supplementarity restrictions the distortionary effect of the levy (its deadweight loss) rises sharply with the tax rate. With them the deadweight loss is close to zero.

Soil carbon sequestration and the CDM. Opportunities and challenges for Africa

Energy Technology Data Exchange (ETDEWEB)

Ringius, Lasse

1999-12-17

The agriculture sector dominates the economies of most sub-Saharan countries, contributing about one-third of the region's GDP, accounting for forty percent of the export, and employing about two-thirds of the economically active population. Moreover, some soils in sub-Saharan Africa could, by providing sinks for carbon sequestration, play an important role in managing global climate change. Improvements in agricultural techniques and land use practices could lead to higher agricultural productivity and accumulate soil carbon. Hence, soil carbon sequestration could produce local economic income as well as social and other benefits in Africa. The Clean Development Mechanism (CDM) established in the 1997 Kyoto Protocol is designed to give developed countries with high domestic abatement cost access to low-cost greenhouse gas abatement projects in developing countries, and to benefit developing countries selling projects to investors in developed countries. It is presently unclear whether the CDM will provide credit for sink enhancement and permit broader sink activities. Unfortunately, few cost estimates of soil carbon sequestration strategies presently exist. While these costs are uncertain and all input costs have not been estimated, manure-based projects in small-holdings in Kenya could increase maize yield significantly and sequester one ton of soil carbon for a net cost of -US$806. Clearly, such projects would be very attractive economically. There is presently an urgent need to launch useful long-term (>10 years) field experiments and demonstration projects in Africa. Existing data are not readily comparable, it is uncertain how large amount of carbon could be sequestered, findings are site-specific, and it is unclear how well the sites represent wider areas. To develop CDM projects, it is important that experimental trials generate reliable and comparable data. Finally, it will be important to estimate local environmental effects and economic benefits

Enabling optimal energy options under the Clean Development Mechanism

Gilau, Asmerom M.; Van Buskirk, Robert; Small, Mitchell J.

2007-01-01

This paper addresses the cost effectiveness of renewable energy technologies in achieving low abatement costs and promoting sustainable developments under the Clean Development Mechanism (CDM). According to the results of our optimal energy option's analysis, at project scale, compared with a diesel-only energy option, photovoltaic (PV)-diesel (PVDB), wind-diesel (WDB) and PV-wind-diesel (PVWDB) hybrids are very cost-effective energy options. Moreover, energy options with high levels of renewable energy, including 100% renewables, have the lowest net present cost and they are already cost effective without CDM. On the other hand, while the removal of about 87% carbon dioxide emissions could be achieved at negative cost, initial investment could increase by a factor of 40, which is one of the primary barriers hindering wider renewable energy applications in developing countries, among others. Thus, in order to increase developing countries' participation in the carbon market, CDM policy should shift from a purely market-oriented approach to investigating how to facilitate renewable energy projects through barrier removal. Thus, we recommend that further research should focus on how to efficiently remove renewable energy implementation barriers as a means to improve developing countries' participation in meaningful emission reduction while at the same time meeting the needs of sustainable economic development

The clean development mechanism (CDM) provides a way of assisting sustainable development in developing countries for developed countries to reduce greenhouse gas (GHG) emissions. Despite its intended benefits, the primary CDM market decreased from US$5.8 billion in 2006 to US$1.5 billion in 2010. One of the primary reasons for the reduction of market size is that developed countries as investors have a high level of risks caused by the volatility of the market price for certified emission reductions (CERs). Another issue to be resolved is that developing countries as host countries cannot claim any right to the CERs produced on their own land. This paper presents a real option-based model for both parties (developed and developing countries) to have their fair share of profits and risks by controlling the uncertainty associated with the future value of CERs. A case study illustrated that the proposed model can effectively attract investors to CDM projects leading to mitigation of climate change. - Highlights: ► This study focused on the risks associated with the uncertainty of future CER value in CDM projects. ► A real option-based model was developed for both parties in CDM to have fair share of profit and risk. ► Key variables and boundary conditions were identified for application of real option to CDM. ► The model allowed both parties to own options, which have an identical value. ► Hydropower plant projects in Indonesia were used to illustrate the implementation of the model

Optimal sampling plan for clean development mechanism energy efficiency lighting projects

2013-01-01

Highlights: • A metering cost minimisation model is built to assist the sampling plan for CDM projects. • The model minimises the total metering cost by the determination of optimal sample size. • The required 90/10 criterion sampling accuracy is maintained. • The proposed metering cost minimisation model is applicable to other CDM projects as well. - Abstract: Clean development mechanism (CDM) project developers are always interested in achieving required measurement accuracies with the least metering cost. In this paper, a metering cost minimisation model is proposed for the sampling plan of a specific CDM energy efficiency lighting project. The problem arises from the particular CDM sampling requirement of 90% confidence and 10% precision for the small-scale CDM energy efficiency projects, which is known as the 90/10 criterion. The 90/10 criterion can be met through solving the metering cost minimisation problem. All the lights in the project are classified into different groups according to uncertainties of the lighting energy consumption, which are characterised by their statistical coefficient of variance (CV). Samples from each group are randomly selected to install power meters. These meters include less expensive ones with less functionality and more expensive ones with greater functionality. The metering cost minimisation model will minimise the total metering cost through the determination of the optimal sample size at each group. The 90/10 criterion is formulated as constraints to the metering cost objective. The optimal solution to the minimisation problem will therefore minimise the metering cost whilst meeting the 90/10 criterion, and this is verified by a case study. Relationships between the optimal metering cost and the population sizes of the groups, CV values and the meter equipment cost are further explored in three simulations. The metering cost minimisation model proposed for lighting systems is applicable to other CDM projects as

Cleaner generation, free-riders, and environmental integrity: clean development mechanism and the power sector

This article provides a first-cut estimate of the potential impacts of the clean development mechanism (CDM) on electricity generation and carbon emissions in the power sector of non-Annex 1 countries. We construct four illustrative CDM regimes that represent a range of approaches under consideration within the climate community. We examine the impact of these CDM regimes on investments in new generation, under illustrative carbon trading prices of US$ 10 and 100/tC. In the cases that are most conductive to CDM activity, roughly 94% of new generation investments remains identical to the without-CDM situation, with only 6% shifting from higher to lower carbon intensity technologies. We estimate that the CDM would bolster renewable energy generation by as little as 15% at US$ 10/tC, or as much as 300% at US$ 100/tC. A striking finding comes from our examination of the potential magnitude of the 'free-rider' problem, i.e. crediting of activities that will occur even in the absence of the CDM. The CDM is intended to be globally carbon-neutral --- a project reduces emissions in the host country but generates credits that increase emissions in the investor country. However, to the extent that unwarranted credits are awarded to non-additional projects, the CDM would increase global carbon emissions above the without-CDM emissions level. Under two of the CDM regimes considered, cumulative free-riders credits total 250-600MtC through the end of the first budget period in 2012. This represents 10-23% of the likely OECD emissions reduction requirement during the first budget period. Since such a magnitude of free-rider credits from non-additional CDM projects could threaten the environmental integrity of the Kyoto protocol, it is imperative that policy makers devise CDM rules that encourage legitimate projects, while effectively screening out non-additional activities.

The paper deals with the diffusion of GHG mitigation technologies in developing countries. We develop a model where an abatement technology is progressively adopted by firms and we use it to compare the Clean Development Mechanism (CDM) with a standard Cap and Trade scheme (C and T). In the presence of learning spillovers, we show that the CDM yields a higher social welfare than C and T if the first adopter receives CDM credits whereas the followers do not. This result lends support to the policy proposal of relaxing the CDM additionality constraint for projects which generate significant learning externalities. (authors)

2012-06-01

Full Text Available The aim in this study is to identify the tax treatment applied to carbon credit operations in Brazilian companies that are developing projects in the context of the Clean Development Mechanism (CDM. Therefore, an exploratory research with a qualitative approach was developed. Data were collected with the help of questionnaire, forwarded to all Brazilian companies with CDM projects that received approval from the Inter-Ministerial Commission on Global Climate Change (CIMGC without safeguards, according to the list of the Brazilian Ministry of Science and Technology. Out of 117 companies listed, only five answered the research instrument, which represents an accessibility sample. The results show that, as for the tax treatment applied in the companies under analysis, IRPJ and CSLL should be charged on carbon credit operations. Regarding PIS, COFINS, ISS, some companies considered that these taxes are due and others that they are not. There is a consensus, though, about the fact that ICMS and IOF should not be charged. In conclusion, no uniform understanding exists as of yet about due taxes in the research sample, as no specific fiscal legislation exists yet on carbon credits in Brazil.

Control Drive Mechanisms (CDM) are used in the Light Water Breeder reactor to position Movable Fuel Assemblies weighing in excess of one ton each for purposes of reactivity control. These mechanisms are the first of a kind designed for loads of that magnitude. This report presents a summary of the design and performance of the CDM and includes discussions of the principles of operation, unique design features, and fabrication methods of this large, high load capacity CDM. The extensive design acceptance test program and the Shippingport plant periodic testing are summrized as are lessons learned during assembly of the CDM's to the reactor. These CDM's operated successfully to control the light water breeder core at the Shippingport Station from initial criticality in August 1977 to the final shutdown in October 1982. All test and operative data were within expected bands

A correction in the CDM methodological tool for estimating methane emissions from solid waste disposal sites.

Science.gov (United States)

Santos, M M O; van Elk, A G P; Romanel, C

2015-12-01

Solid waste disposal sites (SWDS) - especially landfills - are a significant source of methane, a greenhouse gas. Although having the potential to be captured and used as a fuel, most of the methane formed in SWDS is emitted to the atmosphere, mainly in developing countries. Methane emissions have to be estimated in national inventories. To help this task the Intergovernmental Panel on Climate Change (IPCC) has published three sets of guidelines. In addition, the Kyoto Protocol established the Clean Development Mechanism (CDM) to assist the developed countries to offset their own greenhouse gas emissions by assisting other countries to achieve sustainable development while reducing emissions. Based on methodologies provided by the IPCC regarding SWDS, the CDM Executive Board has issued a tool to be used by project developers for estimating baseline methane emissions in their project activities - on burning biogas from landfills or on preventing biomass to be landfilled and so avoiding methane emissions. Some inconsistencies in the first two IPCC guidelines have already been pointed out in an Annex of IPCC latest edition, although with hidden details. The CDM tool uses a model for methane estimation that takes on board parameters, factors and assumptions provided in the latest IPCC guidelines, while using in its core equation the one of the second IPCC edition with its shortcoming as well as allowing a misunderstanding of the time variable. Consequences of wrong ex-ante estimation of baseline emissions regarding CDM project activities can be of economical or environmental type. Example of the first type is the overestimation of 18% in an actual project on biogas from landfill in Brazil that harms its developers; of the second type, the overestimation of 35% in a project preventing municipal solid waste from being landfilled in China, which harms the environment, not for the project per se but for the undue generated carbon credits.

A dynamic charge description master (CDM) integrates information from clinical ancillary systems into the charge-capture process, so an organization can reduce its reliance on the patient accounting system as the sole source of billing information. By leveraging the information from electronic ancillary systems, providers can eliminate the need for paper charge-capture forms and see increased accuracy and efficiency in the maintenance of billing information. Before embarking on a dynamic CDM strategy, organizations should first determine their goals for implementing an EHR system, include revenue cycle leaders on the EHR implementation team, and carefully weigh the pros and cons of CDM design decisions.

Highlights: • A metering cost minimisation model is built with the lamp population decay to optimise CDM lighting projects sampling plan. • The model minimises the total metering cost and optimise the annual sample size during the crediting period. • The required 90/10 criterion sampling accuracy is satisfied for each CDM monitoring report. - Abstract: This paper proposes a metering cost minimisation model that minimises metering cost under the constraints of sampling accuracy requirement for clean development mechanism (CDM) energy efficiency (EE) lighting project. Usually small scale (SSC) CDM EE lighting projects expect a crediting period of 10 years given that the lighting population will decay as time goes by. The SSC CDM sampling guideline requires that the monitored key parameters for the carbon emission reduction quantification must satisfy the sampling accuracy of 90% confidence and 10% precision, known as the 90/10 criterion. For the existing registered CDM lighting projects, sample sizes are either decided by professional judgment or by rule-of-thumb without considering any optimisation. Lighting samples are randomly selected and their energy consumptions are monitored continuously by power meters. In this study, the sampling size determination problem is formulated as a metering cost minimisation model by incorporating a linear lighting decay model as given by the CDM guideline AMS-II.J. The 90/10 criterion is formulated as constraints to the metering cost minimisation problem. Optimal solutions to the problem minimise the metering cost whilst satisfying the 90/10 criterion for each reporting period. The proposed metering cost minimisation model is applicable to other CDM lighting projects with different population decay characteristics as well

CO2 emissions mitigation potential of solar home systems under clean development mechanism in India

International Nuclear Information System (INIS)

Purohit, Pallav

2009-01-01

The Government of India has taken several initiatives for promotion of solar energy systems in the country during the last two decades. A variety of policy measures have been adopted which include provision of financial and fiscal incentives to the potential users of solar energy systems however, only 0.4 million solar home systems (SHSs) have been installed so far that is far below their respective potential. One of the major barriers is the high costs of investments in these systems. The clean development mechanism (CDM) of the Kyoto Protocol provides industrialized (Annex-I) countries with an incentive to invest in emission reduction projects in developing (non-Annex-I) countries to achieve a reduction in carbon dioxide (CO 2 ) emissions at lowest cost that also promotes sustainable development in the host country. SHSs could be of interest under the CDM because they directly displace greenhouse gas (GHG) emissions while contributing to sustainable rural development, if developed correctly. In this study an attempt has been made to estimate the CO 2 mitigation potential of SHSs under CDM in India.

Operationalizing clean development mechanism baselines: A case study of China's electrical sector

Science.gov (United States)

Steenhof, Paul A.

The global carbon market is rapidly developing as the first commitment period of the Kyoto Protocol draws closer and Parties to the Protocol with greenhouse gas (GHG) emission reduction targets seek alternative ways to reduce their emissions. The Protocol includes the Clean Development Mechanism (CDM), a tool that encourages project-based investments to be made in developing nations that will lead to an additional reduction in emissions. Due to China's economic size and rate of growth, technological characteristics, and its reliance on coal, it contains a large proportion of the global CDM potential. As China's economy modernizes, more technologies and processes are requiring electricity and demand for this energy source is accelerating rapidly. Relatively inefficient technology to generate electricity in China thereby results in the electrical sector having substantial GHG emission reduction opportunities as related to the CDM. In order to ensure the credibility of the CDM in leading to a reduction in GHG emissions, it is important that the baseline method used in the CDM approval process is scientifically sound and accessible for both others to use and for evaluation purposes. Three different methods for assessing CDM baselines and environmental additionality are investigated in the context of China's electrical sector: a method based on a historical perspective of the electrical sector (factor decomposition), a method structured upon a current perspective (operating and build margins), and a simulation of the future (dispatch analysis). Assessing future emission levels for China's electrical sector is a very challenging task given the complexity of the system, its dynamics, and that it is heavily influenced by internal and external forces, but of the different baseline methods investigated, dispatch modelling is best suited for the Chinese context as it is able to consider the important regional and temporal dimensions of its economy and its future development

ESD full chip simulation: HBM and CDM requirements and simulation approach

2008-05-01

Full Text Available Verification of ESD safety on full chip level is a major challenge for IC design. Especially phenomena with their origin in the overall product setup are posing a hurdle on the way to ESD safe products. For stress according to the Charged Device Model (CDM, a stumbling stone for a simulation based analysis is the complex current distribution among a huge number of internal nodes leading to hardly predictable voltage drops inside the circuits.

This paper describes an methodology for Human Body Model (HBM simulations with an improved ESD-failure coverage and a novel methodology to replace capacitive nodes within a resistive network by current sources for CDM simulation. This enables a highly efficient DC simulation clearly marking CDM relevant design weaknesses allowing for application of this software both during product development and for product verification.

The emissions of Greenhouse Gases (GHG), the resulting intensification of the greenhouse effect and its relation with climate change, have been pointed out as serious global problem. For this reason, the Kyoto Protocol was established, within the United Nations Framework Convention on Climate Change (UNFCCC), with the objective of setting up directives and goals to the stabilization and reduction of GHG emissions. In its Article 12, the Kyoto Protocol institutes the Clean Development Mechanism, an important flexibility instrument to Annex 1 Parties in achieving their emission reduction targets through project implementation in developing countries (non-Annex 1 Parties), promoting Sustainable Development and incurring and lesser costs of emission reductions. Any project, to be qualified within the Clean Development Mechanism, must fulfill the eligibility criterions fixed by the Kyoto Protocol, which are: promotion of Sustainable Development and assurance of the project additionality. In Brazil, the sugarcane industry is a promising opportunity of developing these kind of projects, specially by means of the cogeneration from sugarcane residues. This paper analyses the Additionality of this sort of projects, in the light of the criterions defined by the UNFCCC, with special attention to the two Brazilian cases registered in the CDM Methodologies Panel.

With ever growing urgency, climate change mitigation is fast becoming a priority for China. A successful policy of implementing and expanding sustainable development and the use of renewable energy is therefore vital. As well as long-term and near-term targets for installed capacity of renewable energy, in its 12th five-year plan, China has created strict and ambitious carbon intensity targets for each province. This study proposes an inter-provincial clean development mechanism to assist in meeting these targets. This mechanism will create potential co-benefits of assisting in sustainable development in lesser developed provinces, increasing local air quality and supporting the growth of China's renewable energy sector. This paper also highlights the potential that this inter-provincial clean development mechanism has in accelerating the growth of the domestic solar photovoltaics (PV) sector, for which the market in China is still in its infancy. - Highlights: ► We recognise the necessity for each province in China to reduce its GHG emissions. ► We assess the potential of a national scale a CDM style mechanism for China. ► We consider the effect that the national CDM could have on solar PV in China

Clean development mechanism PDD guidebook: Navigating the pitfalls

Energy Technology Data Exchange (ETDEWEB)

Kamel, S. (ed.)

2005-11-01

This guidebook is designed to help readers navigate the pitfalls of preparing a Project Design Document (PDD) for Clean Development Mechanism (CDM) projects. The purpose of a PDD is to prepare project information for relevant stakeholders. These stakeholders include the investment community, the Designated Operating Entity (DOE) performing validation of the project, the CDM Executive Board (EB), the Designated National Authorities (DNA) of the involved countries and the local population. The PDD, together with the validation report and the approval letter of the DNA, are the basis for the registration of the project and its recognition as a credible CDM project. The PDD is about the project's design that is, how the project intends to reduce greenhouse gas (GHG) emissions below those levels that would otherwise have been emitted. Each and every CDM project is unique, from the project design to the application of even the simplest baseline methodology. Some of the projects submitted for validation may be very efficient in reducing emissions and score well in terms of economic, social and environmental benefits, but may still not qualify as CDM projects. Experience has shown that the information needed to judge a suitability of a project for the CDM is vast and can take months to assemble. Also, the time required to assemble relevant information increases with the number and diversity of stakeholders involved and the complexity of the information itself. This guidebook is based on a review of all PDDs submitted to DNV for validation. The advice given and the pitfalls described in this guidebook are, therefore, based on day-to-day, hands-on experience and real instances of mistakes made in submissions. In summary, then, this guidebook takes a practical stance: it is concerned with the practical issues of how to get projects through the validation process. It will help those submitting a PDD by: 1) Describing the most common and costly mistakes made in the process

Carbon dioxide (CO2) is one of the major pollutants among greenhouse gases emitted by fossil fuel based power plants and responsible for environmental tribulations. Therefore diminution of carbon dioxide level by Clean Development Mechanism (CDM) is now serious concern worldwide. This paper evaluates the emission factors of national electric grid in Oman and proposes a wind energy based CDM project to diminish the CO2 emissions. Estimations show that operating margin emission factors of national grid during five years lies in the range of 0.74 to 0.69 kg CO2/kWh. Further, proposed CDM project revealed the annual baseline emissions reduction of 45552 ton CO2 and able to earn the revenue of US$ 61.49 million by certify emission reductions in the first crediting period of project. Paper also critically analyse the opportunities for CDM project, its lucrative aspect, barrier and challenges.

Promotion of energy conservation in developing countries through the combination of ESCO and CDM: A case study of introducing distributed energy resources into Chinese urban areas

The implementation of an energy service company (ESCO) project in developing countries may result not only in reduced energy cost but also in considerable environmental benefits, including the reduction of CO 2 emissions, which can be assessed in an economic manner under the Clean Development Mechanism (CDM) scheme. In this way, the economic and environmental benefits of energy conservation activities can be enjoyed by both the investor and the end-user, which can reduce the investment risk and realize a rational profit allocation. This study presents a numerical analysis of the introduction of distributed energy resources (DER) into a Chinese urban area. An optimization model is developed to determine the energy system combination under the constraints on the electrical and thermal balances and equipment availability. According to the simulation results, the introduction of DER systems possesses considerable potential to reduce CO 2 emissions, especially when considering that the economic profit of the CO 2 credit will increase the incentive to adopt DER systems to an even greater extent. Furthermore, by sharing the energy cost savings with the investors under an ESCO framework, the investment risk can be further reduced, and the conditions required for the project to qualify for CDM can be relaxed. Highlights: ► An investor focused analytical model is developed to aid the investment of a DER system. ► The combination of ESCO and CDM enhances the incentive to introduce energy conservation measures. ► Electricity buy-back is effective in boosting the DER system adoption under the proposed framework. ► The increased energy cost savings allocated to the investor promotes the DER system adoption. ► The rational allocation of CER credits is of vital importance to the success of the project.

Defined in the article 12 from Kyoto Protocol, the Clean Development Mechanism (CDM) was created as a market instrument. As a consequence, CDM projects distribution is becoming unequal among the regions of the globe and also among project activities types. Brazil is the second in number of projects and the third in emission reductions, but the market aspect of CDM is a factor that influences the domestic dynamics of CDM. In this way, the objective of this paper is to evaluate in which way the regional and technological differences between CDM projects are replicable in the national context. In order to meet this aim, it was assessed all Brazilian CDM projects that were submitted to UN until March 10{sup th} 2006. As a result, it could be identified that there is not any land use, land-use change and forestry (LULUCF CDM) projects, besides the Brazilian potential in this field, it could be noticed that the most part of Brazilian CDM projects is focused in renewable energy promotion, such as cogeneration with biomass and small hydro power plants and that there is a small number of projects related to energy efficiency. In addition, it was verified wide differences regarding regional distribution of projects and the predominance of unilateral initiatives. (author)

An agreement on CDM rules is important both for industrialized and developing countries. As a flexibility mechanism, it will allow industrialized countries to benefit from low cost emission reductions but the CDM, as a main goal, should also stimulate a more sustainable economic development in DCs. The CDM is the sole instrument, with GEF, proposed for DCs participation into climate change prevention. This situation satisfies a majority of DCs, but CDM may not offer sufficient perspectives for some countries with rapid industrialization given the huge economic stakes linked to the creation of a carbon credits market between Annex I countries. The operationality of the CDM is not yet established and important questions, as environmental additionality, are still unresolved. Here we first examine the rules in order to validate project additionality and their possible consequences on the effectiveness and the scope of the mechanism. The different reactions of major DCs groups on the structure of the mechanism will then be analysed. This will lead us to examine the possibilities to enlarge participation of DCs in climate change prevention according to the apparent wish of semi-industrialized countries. (author)

The Clean Development Mechanism (CDM) under the Kyoto Protocol to the United Nations Framework Convention on Climate Change is considered a key instrument to encourage developing countries' participation in the mitigation of global climate change. Reduction of greenhouse gas (GHG) emissions through the energy supply and demand side activities are the main options to be implemented under the CDM. This paper analyses the general equilibrium effects of a supply side GHG mitigation option-the substitution of thermal power with hydropower--in Thailand under the CDM. A static multi-sector general equilibrium model has been developed for the purpose of this study. The key finding of the study is that the substitution of electricity generation from thermal power plants with that from hydropower plants would increase economic welfare in Thailand. The supply side option would, however, adversely affect the gross domestic product (GDP) and the trade balance. The percentage changes in economic welfare, GDP and trade balance increase with the level of substitution and the price of certified emission reduction (CER) units.

Recent anomalies found in cosmological datasets such as the low multipoles of the Cosmic Microwave Background or the low redshift amplitude and growth of clustering measured by e.g., abundance of galaxy clusters and redshift space distortions in galaxy surveys, have motivated explorations of models beyond standard ΛCDM. Of particular interest are models where general relativity (GR) is modified on large cosmological scales. Here we consider deviations from ΛCDM+GR within the context of Horndeski gravity, which is the most general theory of gravity with second derivatives in the equations of motion. We adopt a parametrization in which the four additional Horndeski functions of time α{sub i}(t) are proportional to the cosmological density of dark energy Ω{sub DE}(t). Constraints on this extended parameter space using a suite of state-of-the art cosmological observations are presented for the first time. Although the theory is able to accommodate the low multipoles of the Cosmic Microwave Background and the low amplitude of fluctuations from redshift space distortions, we find no significant tension with ΛCDM+GR when performing a global fit to recent cosmological data and thus there is no evidence against ΛCDM+GR from an analysis of the value of the Bayesian evidence ratio of the modified gravity models with respect to ΛCDM, despite introducing extra parameters. The posterior distribution of these extra parameters that we derive return strong constraints on any possible deviations from ΛCDM+GR in the context of Horndeski gravity. We illustrate how our results can be applied to a more general frameworks of modified gravity models.

We test the consistency between Planck temperature and polarization power spectra and the concordance model of Λ Cold Dark Matter cosmology (ΛCDM) within the framework of Crossing statistics. We find that Planck TT best fit ΛCDM power spectrum is completely consistent with EE power spectrum data while EE best fit ΛCDM power spectrum is not consistent with TT data. However, this does not point to any systematic or model-data discrepancy since in the Planck EE data, uncertainties are much larger compared to the TT data. We also investigate the possibility of any deviation from ΛCDM model analyzing the Planck 2015 data. Results from TT, TE and EE data analysis indicate that no deviation is required beyond the flexibility of the concordance ΛCDM model. Our analysis thus rules out any strong evidence for beyond the concordance model in the Planck spectra data. We also report a mild amplitude difference comparing temperature and polarization data, where temperature data seems to have slightly lower amplitude than expected (consistently at all multiples), as we assume both temperature and polarization data are realizations of the same underlying cosmology.

Composting projects under the Clean Development Mechanism: Sustainable contribution to mitigate climate change

International Nuclear Information System (INIS)

Rogger, Cyrill; Beaurain, Francois; Schmidt, Tobias S.

2011-01-01

The Clean Development Mechanism (CDM) of the Kyoto Protocol aims to reduce greenhouse gas emissions in developing countries and at the same time to assist these countries in sustainable development. While composting as a suitable mitigation option in the waste sector can clearly contribute to the former goal there are indications that high rents can also be achieved regarding the latter. In this article composting is compared with other CDM project types inside and outside the waste sector with regards to both project numbers and contribution to sustainable development. It is found that, despite the high number of waste projects, composting is underrepresented and a major reason for this fact is identified. Based on a multi-criteria analysis it is shown that composting has a higher potential for contribution to sustainable development than most other best in class projects. As these contributions can only be assured if certain requirements are followed, eight key obligations are presented.

Scoping paper on new CDM baseline methodology for cross-border power trade

2011-07-01

Poeyry has been sub-contracted by Carbon Limits, under the African Development Bank CDM Support Programme, to prepare a new CDM baseline methodology for cross border trade, based on a transmission line from Ethiopia to Kenya. The first step in that process is to review the response of the UNFCCC, particularly the Methodologies Panel ('Meth Panel') of the CDM Executive Board, to the various proposals on cross-border trade and interconnection of grids. This report reviews the Methodology Panel and Executive Board decisions on 4 requests for revisions of ACM2 'Consolidated baseline methodology for grid-connected electricity generation from renewable sources', and 5 proposed new baseline methodologies (NM255, NM269, NM272, NM318, NM342), all of which were rejected. We analyse the reasons the methodologies were rejected, and whether the proposed draft Approved Methodology (AM) that the Methodology Panel created in response to NM269 and NM272 is a suitable basis for a new methodology proposal.(auth)

Forest conservation and the clean development mechanism. Lessons from the Costa Rican protected areas project

International Nuclear Information System (INIS)

Voehringer, F.

2004-01-01

Deforestation is currently the source of about 20% of anthropogenic CO2 emissions. Avoided deforestation has, nonetheless, been ruled out as a Clean Development Mechanism (CDM) category in the Kyoto Protocol's first commitment period, because several methodological issues were considered too difficult to resolve. This paper explores whether CDM issues such as (1) carbon quantification, (2) additionality and baseline setting, (3) leakage risks, (4) non-permanence risks, and (5) sustainable development can be adequately dealt with in large, diversified forest conservation projects. To this aim, it studies the case of the Costa Rican Protected Areas Project (PAP), an Activities Implemented Jointly (AIJ) project which was meant to consolidate the national park system to avoid deforestation, promote the growth of secondary forests and regenerate pastures on an area that, in total, covers 10% of the national territory. The case study examines how the issues mentioned above have been addressed in the project design and in the certification process. It is found that baseline uncertainties are the major problem in this case. Nonetheless, the case suggests the possibility to address CDM issues by specific requirements for project design and very conservative and temporary crediting. Provided that other case studies support this conclusion, eligibility of well-designed forest conservation projects under the CDM in the second commitment period may be worth considering, given the secondary benefits of avoided deforestation

Several aspects are considered successively: damage definitions and measures, damage growth equations and anisotropy effects, and use of CDM for local approaches of fracture. Various materials, loading conditions and damaging processes are incorporated in the same general framework. Particular attention is given to the possible connections between different definitions of damage, especially between the CDM definition and the information obtained from material science. (orig.)

Global climate change policies. An analysis of CDM policies with an adapted GTAP model

Wang, Shunli

In the context of the relationships between spatial-economic interaction and global warming just discussed, this study aims to analyze the Clean Development Mechanisms (CDM) policies from an economic point of view. The research question of this study is formulated as follows: What will be the impacts of clirnate change policies, in particular CDM policies, on the economic performance of (groups of) countries in our global economic system, taking spatial interaction and general equilibrium effects into account? The purpose of addressing the issue of economic performance for (groups of) countries in the economic system is not just to identify winners and losers from international treaties. Rather, winning or losing may even determine the implementation and willingness of individual countries to participate in international environmental treaties, as illustrated by the recent withdrawal of the US from the Kyoto Protocol. By analyzing the economic impacts of an international environmental treaty for individual (groups of) countries, the framework that will be used to analyze this research question may be useful to determine the attractiveness of some global environmental policies, both for the world as a whole and for individual (groups of) countries. The research question will be answered by dividing it into six subquestions: (1) What is the position of CDM policies in the broad context of climate policy regimes?; (2) How should the relationship between human behavior and the physical environment be ideally modeled from an economic perspective? (3) How should the spatial dimension be incorporated in this framework of interaction between the economic and ecological system?; (4) How can climate change issues be incorporated in general equilibrium models in general, and in GTAP-E (extension of the Global Trade Analysis Project) in particular?; (5) How can CDM policies be implemented in the GTAP-E model?; and (6) What are the impacts of these climate change policies on

The majority of the Middle East and North Africa (MENA) countries possess substantial potential for the implementation of CDM projects. Abatement of Greenhouse Gas (GHG) emissions can mainly be achieved through utilizing the abundant Renewable Energy Sources (RES) in the region and the implementation of Energy Efficiency (ENEF) measures. However, most of the MENA countries have a limited track record as regards CDM projects in the pipeline comparing to the major CDM-players, like Asia-Pacific regions and Latin America. In the above framework, this paper investigates the current status of CDM in the MENA region and the related perspectives for further diffusion of the CDM though the elaboration of a Strengths-Weaknesses-Opportunities and Threats (SWOT) Analysis. Particular emphasis is laid on the case of Israel, which seems to make an exception to the rule, since it hosts most projects in the region and dominates among the MENA countries.

Risks and chances of combined forestry and biomass projects under the Clean Development Mechanism

Dutschke, Michael; Kapp, Gerald; Lehmann, Anna; Schaefer, Volkmar (Hamburg Inst. International Economics (Germany))

2006-06-15

The Clean Development Mechanism (CDM) aims at reducing greenhouse gas (GHG) emissions, while at the same time taking up CO{sub 2} from the atmosphere in vegetation by means of afforestation and reforestation. In spite of these options being complementary, rules and modalities for both project classes are being treated separately in the relevant decisions by the Conference of the Parties to the UN Framework Convention on Climate Change. The present study reviews the state of bioenergy use in developing countries, modalities and procedures under the CDM, and the potential for transaction cost reduction in climate mitigation projects. There are four potential types of combinations in the matrix between small-scale - large-scale / afforestation and reforestation - bioenergy activities. We develop criteria for assessing sustainable development benefits and present an example project for each of the potential project types. We find that the individual risks of single-category projects do not increase when combining project categories and that each combination holds potential for integrated sustainability benefits. Risks for local livelihoods do increase with project size, but a transparent, participatory planning phase is able to counterbalance smallholders' lack of negotiation power. Further research will have to develop concrete project examples and blueprints with approved CDM methodologies, thereby decreasing transaction costs and risk for all potential project partners. (au)

The authors of the contribution analyze the developments in law, legal interpretation issues as well as climate political and development political effects of the Clean Development Mechanism (CDM) as an element of transnational climate change law which is associated with the states and emission trading (ETS). In the basic intention CDM shall achieve a climate-neutral reduction of costs of climate policy at the simultaneous promotion of development political goals where industrial countries may provide their global or European targets of reduction in part by means of measures in emerging or developing countries rather than by means of local climate protection. However, the specific CDM projects prove to be questionable with respect to the climate policy and development policy. This also is related to enforcement problems that represent a variant of the general environment legal problem of the latent 'interest identity of inspectors and controlled persons'. The proposed European legal and the possible international (land use related) developments of the CDM since 2013 and currently in Cancun probably will not change essentially the fundamental but intensify it even more. With all that, at the same time a kind of exemplary governance analysis arises in the context of the ETS by means of one essential part of its aspects - as well as generally in the context to the perspectives of climate policy according to Cancun.

Renewable Energy Investment in Emerging Markets: Evaluating Improvements to the Clean Development Mechanism

Directory of Open Access Journals (Sweden)

Amy Tang

2014-06-01

Full Text Available In the past, industrialized countries have invested in or financed numerous renewable energy projects in developing countries, primarily through the Clean Development Mechanism (CDM of the Kyoto Protocol. However, critics have pointed to its bureaucratic structure, problems with additionality and distorted credit prices as ill-equipped to streamline renewable energy investment. In this paper, we simulate the impact of policy on investment decisions on whether or not to invest in wind energy infrastructure in India, Brazil and China. Data from 2,578 past projects as well as literature on investor behaviour is used to inform the model structure and parameters. Our results show that the CDM acts differently in each country and reveal that while streamlining the approval process and reconsidering additionality can lead to non-trivial increase in total investment, stabilizing policy and decreasing investment risk will do the most to spur investment.

Economic and Environmental Performances of Small-Scale Rural PV Solar Projects under the Clean Development Mechanism: The Case of Cambodia

Directory of Open Access Journals (Sweden)

Ellen De Schepper

2015-09-01

Full Text Available The two core objectives of the Clean Development Mechanism (CDM are cost-effective emission reduction and sustainable development. Despite the potential to contribute to both objectives, solar projects play a negligible role under the CDM. In this research, the greenhouse gas mitigation cost is used to evaluate the economic and environmental performances of small-scale rural photovoltaic solar projects. In particular, we compare the use of absolute and relative mitigation costs to evaluate the attractiveness of these projects under the CDM. We encourage the use of relative mitigation costs, implying consideration of baseline costs that render the projects profitable. Results of the mitigation cost analysis are dependent on the baseline chosen. To overcome this drawback, we complement the analysis with a multi-objective optimization approach, which allows quantifying the trade-off between economic and environmental performances of the optimal technologies without requiring a baseline.

The Clean Development Mechanism Re-engineered

for engineering such mechanism, or indeed reengineering the CDM itself, to make it a viable mitigation financing tool, providing receipts for payments in the form of certified emission reductions (CER). Two solutions are presented, both of which secure new financing for projects that deliver real and measurable...... emissions reduction benefits on the basis of prospective revenues from emissions reduction: one introduces up-front securitization of the emissions reductions; the other builds on a defined value of the CERs without the need for a carbon price or a market for trading. Most of us use simple heuristics...... time. Simply put CERs are not project finance and do not address project capital needs when most needed — upfront. CER based returns are available only after a project is operational. That is why only one third of registered CDM projects went as far as to get their carefully calculated CERs issued...

Tendances Carbone no. 75 'The CDM: let's not discard a tool that raised over US$ 200 billion'

2012-01-01

Among the publications of CDC Climat Research, 'Tendances Carbone' bulletin specifically studies the developments of the European market for CO 2 allowances. This issue addresses the following points: Everyone wonders which miraculous instrument will enable the Green Climate Fund to mobilize the pledged US$100 billion per year in climate finance by 2020. Developing countries are now asking for interim targets to quench their mounting skepticism that this level of commitment can be reached. In the meantime paradoxically, the Clean Development Mechanism (CDM) - a tool that managed to leverage over US$200 billion of mostly private investment for climate change mitigation - is left dying without much regret

The H II galaxy Hubble diagram strongly favours Rh = ct over ΛCDM

Wei, Jun-Jie; Wu, Xue-Feng; Melia, Fulvio

2016-12-01

We continue to build support for the proposal to use H II galaxies (HIIGx) and giant extragalactic H II regions (GEHR) as standard candles to construct the Hubble diagram at redshifts beyond the current reach of Type Ia supernovae. Using a sample of 25 high-redshift HIIGx, 107 local HIIGx, and 24 GEHR, we confirm that the correlation between the emission-line luminosity and ionized-gas velocity dispersion is a viable luminosity indicator, and use it to test and compare the standard model ΛCDM and the Rh = ct universe by optimizing the parameters in each cosmology using a maximization of the likelihood function. For the flat ΛCDM model, the best fit is obtained with Ω _m= 0.40_{-0.09}^{+0.09}. However, statistical tools, such as the Akaike (AIC), Kullback (KIC) and Bayes (BIC) Information Criteria favour Rh = ct over the standard model with a likelihood of ≈94.8-98.8 per cent versus only ≈1.2-5.2 per cent. For wCDM (the version of ΛCDM with a dark-energy equation of state wde ≡ pde/ρde rather than wde = wΛ = -1), a statistically acceptable fit is realized with Ω _m=0.22_{-0.14}^{+0.16} and w_de= -0.51_{-0.25}^{+0.15} which, however, are not fully consistent with their concordance values. In this case, wCDM has two more free parameters than Rh = ct, and is penalized more heavily by these criteria. We find that Rh = ct is strongly favoured over wCDM with a likelihood of ≈92.9-99.6 per cent versus only 0.4-7.1 per cent. The current HIIGx sample is already large enough for the BIC to rule out ΛCDM/wCDM in favour of Rh = ct at a confidence level approaching 3σ.

Potential of wind power projects under the Clean Development Mechanism in India

Directory of Open Access Journals (Sweden)

Michaelowa Axel

2007-07-01

Full Text Available Abstract Background So far, the cumulative installed capacity of wind power projects in India is far below their gross potential (≤ 15% despite very high level of policy support, tax benefits, long term financing schemes etc., for more than 10 years etc. One of the major barriers is the high costs of investments in these systems. The Clean Development Mechanism (CDM of the Kyoto Protocol provides industrialized countries with an incentive to invest in emission reduction projects in developing countries to achieve a reduction in CO2 emissions at lowest cost that also promotes sustainable development in the host country. Wind power projects could be of interest under the CDM because they directly displace greenhouse gas emissions while contributing to sustainable rural development, if developed correctly. Results Our estimates indicate that there is a vast theoretical potential of CO2 mitigation by the use of wind energy in India. The annual potential Certified Emissions Reductions (CERs of wind power projects in India could theoretically reach 86 million. Under more realistic assumptions about diffusion of wind power projects based on past experiences with the government-run programmes, annual CER volumes by 2012 could reach 41 to 67 million and 78 to 83 million by 2020. Conclusion The projections based on the past diffusion trend indicate that in India, even with highly favorable assumptions, the dissemination of wind power projects is not likely to reach its maximum estimated potential in another 15 years. CDM could help to achieve the maximum utilization potential more rapidly as compared to the current diffusion trend if supportive policies are introduced.

Benefits of clean development mechanism application on the life cycle assessment perspective: a case study in the palm oil industry.

2012-03-01

This study performed an assessment on the beneficial of the Clean Development Mechanism (CDM) application on waste treatment system in a local palm oil industry in Malaysia. Life cycle assessment (LCA) was conducted to assess the environmental impacts of the greenhouse gas (GHG) reduction from the CDM application. Calculations on the emission reduction used the methodology based on AM002 (Avoided Wastewater and On-site Energy Use Emissions in the Industrial Sector) Version 4 published by United Nations Framework Convention on Climate Change (UNFCC). The results from the studies showed that the introduction of CDM in the palm oil mill through conversion of the captured biogas from palm oil mill effluent (POME) treatment into power generation were able to reduce approximate 0.12 tonnes CO2 equivalent concentration (tCO2e) emission and 30 kW x hr power generation per 1 tonne of fresh fruit bunch processed. Thus, the application of CDM methodology on palm oil mill wastewater treatment was able to reduce up to 1/4 of the overall environment impact generated in palm oil mill.

Clean development mechanism and off-grid small-scale hydropower projects: Evaluation of additionality

International Nuclear Information System (INIS)

Tanwar, Nitin

2007-01-01

The global climate change mitigation policies and their stress on sustainable development have made electrification of rural mountainous villages, using small hydro, an attractive destination for potential clean development mechanism (CDM) projects. This invariably involves judging the additionality of such projects. The paper suggests a new approach to judge the additionality of such stand-alone small hydropower projects. This has been done by breaking up additionality into two components: external and local. The external additionality is project developer dependent. For determining the local additionality, the paper takes into account the probability of a village getting electrified over a period of time, which is kept equal to the possible crediting period. This is done by defining an electrification factor (EF) whose value depends on the degree of isolation, financial constraints and institutional constraints encountered while electrifying a mountainous village. Using this EF, the additionality of a CDM project can be judged in a much easier and accurate way. The paper is based on the data and inputs gathered during site visits to many isolated villages located in the eastern Indian Himalayas

Renewable energy projects under the clean development mechanism : myth or reality?

International Nuclear Information System (INIS)

Timilsina, G.

2005-01-01

This paper discussed the fate of Renewable Energy (RE) in Canada. The importance of RE is now increasing from both an environmental and energy security perspective, and has been projected as a key solution to climate change problems. RE is also one of the key greenhouse gas (GHG) mitigation options to be considered under the Clean Development Mechanism (CDM). Canada possesses more than 100 GW of technical potential for RE resources, including wind, solar and small hydro. Less than 10 per cent of this potential has been exploited to date. A number of programs have been developed to facilitate the deployment of Renewable Energy Technologies (RETs), including financial incentives, renewable portfolio standards and green power procurement policies. However, Canadian policies are less aggressive than those of other countries. This study showed that the supply of certified emission reductions (CERs) resulting from negative and low cost CDM options, such as energy efficiency improvements, afforestation and reforestation, could surpass the total demand for CERs during the first commitment period of the Kyoto Protocol. Implementation of RE projects under the CDM could be undermined. It was recommended that increased support of the Global Environment Facility (GEF), use of the Special Climate Change Fund, and special attention to RE from both host and investing countries should become mandatory as alternative strategies to promote RE. In addition, it should be acknowledged that the development of RETs faces a number of barriers and challenges, including competition from conventional energy technologies; lack of customer and investor confidence; regulatory and institutional barriers; and technical barriers such as transmission access. 19 refs., 1 tab

A nonlinear CDM based damage growth law for ductile materials

Science.gov (United States)

Gautam, Abhinav; Priya Ajit, K.; Sarkar, Prabir Kumar

2018-02-01

A nonlinear ductile damage growth criterion is proposed based on continuum damage mechanics (CDM) approach. The model is derived in the framework of thermodynamically consistent CDM assuming damage to be isotropic. In this study, the damage dissipation potential is also derived to be a function of varying strain hardening exponent in addition to damage strain energy release rate density. Uniaxial tensile tests and load-unload-cyclic tensile tests for AISI 1020 steel, AISI 1030 steel and Al 2024 aluminum alloy are considered for the determination of their respective damage variable D and other parameters required for the model(s). The experimental results are very closely predicted, with a deviation of 0%-3%, by the proposed model for each of the materials. The model is also tested with predictabilities of damage growth by other models in the literature. Present model detects the state of damage quantitatively at any level of plastic strain and uses simpler material tests to find the parameters of the model. So, it should be useful in metal forming industries to assess the damage growth for the desired deformation level a priori. The superiority of the new model is clarified by the deviations in the predictability of test results by other models.

We derive lens distortion and magnification profiles of four well known clusters observed with Subaru. Each cluster is very well fitted by the general form predicted for Cold Dark Matter (CDM) dominated halos, with good consistency found between the independent distortion and magnification measurements. The inferred level of mass concentration is surprisingly high, 8 < c{sub vir} < 15 ( = 10.39 {+-} 0.91), compared to the relatively shallow profiles predicted by the {Lambda}CDM model, c{sub vir} = 5.06 {+-} 1.10 (for = 1.25 x 10{sup 15} M{sub {circle_dot}}/h). This represents a 4{sigma} discrepancy, and includes the relatively modest effects of projection bias and profile evolution derived from N-body simulations, which oppose each other with little residual effect. In the context of CDM based cosmologies, this discrepancy implies some modification of the widely assumed spectrum of initial density perturbations, so clusters collapse earlier (z {ge} 1) than predicted (z < 0.5) when the Universe was correspondingly denser.

The ΛCDM model of structure formation makes strong predictions on the concentration and shape of dark matter (DM) halos, which are determined by mass accretion processes. Comparison between predicted shapes and observations provides a geometric test of the ΛCDM model. Accurate and precise measurements needs a full three-dimensional (3D) analysis of the cluster mass distribution. We accomplish this with a multi-probe 3D analysis of the X-ray regular Cluster Lensing and Supernova survey with Hubble (CLASH) clusters combining strong and weak lensing, X-ray photometry and spectroscopy, and the Sunyaev–Zel’dovich effect (SZe). The cluster shapes and concentrations are consistent with ΛCDM predictions. The CLASH clusters are randomly oriented, as expected given the sample selection criteria. Shapes agree with numerical results for DM-only halos, which hints at baryonic physics being less effective in making halos rounder.

Costs of certified emission reductions under the Clean Development Mechanism of the Kyoto Protocol

Rahman, Shaikh M.; Kirkman, Grant A.

2015-01-01

This paper examines the cost structure of certified emission reductions (CERs) through various types of projects under the Clean Development Mechanism (CDM) of the Kyoto Protocol. Using the CDM project data, the costs of CERs and their variation across technology and over time and space are estimated by applying alternative functional forms and specifications. Results show that the average cost of CERs decreases with the project scale and duration, scale and duration effects significantly vary across project types, and there is an upward trend in costs. The results also show that the distribution of the projects in the CDM portfolio or a given location does not strictly follow the relative cost structure, nor does the distribution of the CDM projects in different host countries follow the principle of comparative advantage. More than 84% of the CDM portfolio consists of various energy projects with substantially higher costs of CERs than afforestation and reforestation, industrial and landfill gas reduction, and methane avoidance projects, which are only 12% of all projects. While per unit cost of abatement plays an important role in the bottom-up and top-down models to evaluate emission reduction potential and analyze policy alternatives, the findings contradict the presumption of such models that project investors seek out low-cost opportunities. At the aggregate level, the cost of CER by the projects in Asia and Europe is similar but higher than those hosted in Africa, Americas, and Oceania. Yet more than 83% of the projects in the CDM portfolio are located in Asia; more than 69% of the projects are in China and India alone. China appears to have a comparative advantage (i.e., lowest opportunity cost) in energy efficiency projects, while India has a comparative advantage in hydro power projects and Brazil has a comparative advantage in wind power projects. In contrast, energy efficiency category accounts for only 8% of the CDM projects in China, hydro power

The Clean Development Mechanism (CDM) was adopted in the Kyoto Protocol as a flexibility mechanism to reduce greenhouse gases (GHGs) and has been started with such projects as improving efficiency of individual technology. Although applying various countermeasures to urban areas has significant potentials for reducing GHGs, these countermeasures have not been proposed as CDM projects in the practical stage. A CDM project needs to be validated that it will reduce GHGs additionally compared with a baseline, that is, a predictive value of GHG emissions in the absence of the project. This study examined the introduction of solid waste incineration with electricity generation into three different cities, A, B and C. The main solid waste treatment and the main fuel source are landfill and coal, respectively, in City A, incineration and natural gas in City B, and landfill and hydro in City C. GHG emission reductions of each city under several baseline options assumed here were evaluated. Even if the same technology is introduced, the emission reduction greatly varies according to the current condition and the future plan of the city: 1043-1406 kg CO2/t of waste in City A, 198-580 kg CO2/t in City B, and wide range of zero to over 1000 kg CO2/t in City C. Baseline options also cause significant difference in the emission reduction even in the same city (City C). Incinerating solid waste after removing plastics by source separation in City B increased GHG emission reduction potential up to 730-900 kg CO2/t, which enhances the effectiveness as a CDM project.

Defining Investment Additionality for CDM projects - practical approaches

International Nuclear Information System (INIS)

Greiner, Sandra; Michaelowa, Axel

2003-01-01

The environmental integrity of the CDM under the Kyoto Protocol depends on the possibility to avoid giving emission credits to projects that would have happened anyway. Whether and how 'Investment Additionality' of CDM projects has to be determined is currently a part of climate negotiations. We discuss the rationale of companies to invest in projects and analyse possible criteria to determine Investment Additionality from a theoretical point of view. Differences in the type of investment call for the application of different criteria. Although some criteria are better than others, no single criterion can outweigh the others in all respects. We therefore suggest a scheme for additionality testing that aims at matching types of investment and criteria in a sensible way. Criteria are evaluated on the grounds of robustness to manipulation, degree of coverage and appropriateness for testing the investment decision under consideration

Forest Protection and Reforestation in Costa Rica: Evaluation of a Clean Development Mechanism Prototype.

Science.gov (United States)

Subak

2000-09-01

/ Costa Rica has recently established a program that provides funds for reforestation and forest protection on private lands, partly through the sale of carbon certificates to industrialized countries. Countries purchasing these carbon offsets hope one day to receive credit against their own commitments to limit emissions of greenhouse gases. Costa Rica has used the proceeds of the sale of carbon offsets to Norway to help finance this forest incentive program, called the Private Forestry Project, which pays thousands of participants to reforest or protect forest on their lands. The Private Forestry Project is accompanied by a monitoring program conducted by Costa Rican forest engineers that seeks to determine net carbon storage accomplished on these lands each year. The Private Forestry Project, which is officially registered as an Activity Implemented Jointly, is a possible model for bundled projects funded by the Clean Development Mechanism (CDM) established by the 1997 Kyoto Protocol to the UN Framework Convention on Climate Change. It also serves as an interesting example for the CDM because it was designed by a developing country host-not by an industrialized country investor. Accordingly, it reflects the particular "sustainable development" objectives of the host country or at least the host planners. Early experience in implementing the Private Forestry Project is evaluated in light of the main objectives of the CDM and its precursor-Activities Implemented Jointly. It is concluded that the project appears to meet the criteria of global cost-effectiveness and financing from non-ODA sources. The sustainable development implications of the project are specific to the region and would not necessarily match the ideals of all investing and developing countries. The project may be seen to achieve additional greenhouse gas abatement when compared against some (although not all) baselines.

The Potential of the Market for the Kyoto Mechanisms

International Nuclear Information System (INIS)

Zhang, Z.X.

2000-01-01

The Kyoto Protocol is the first international environmental agreement to set legally binding greenhouse gas (GHG) emissions targets and timetables for Annex I countries. It incorporates emissions trading and two project-based flexibility mechanisms, namely joint implementation (JI) and the clean development mechanism (CDM) to help Annex I countries to meet their Kyoto targets at a lower overall cost. The extent to which their compliance cost can be lowered depends on the size of the market for all three flexibility mechanisms under the Protocol. This article estimates the size of such a market and demonstrates that restrictions on the use of flexibility mechanisms not only reduce potential of the Annex I countries' efficiency gains, but are furthermore not beneficial to developing countries since they restrict the total financial flows to developing countries under the CDM. Thus, from the perspective of husbanding the world's limited resources, the fewer the restrictions on the use of flexibility mechanisms, the greater are the gains from their use

Where the world stands still: turnaround as a strong test of ΛCDM cosmology

Our intuitive understanding of cosmic structure formation works best in scales small enough so that isolated, bound, relaxed gravitating systems are no longer adjusting their radius; and large enough so that space and matter follow the average expansion of the Universe. Yet one of the most robust predictions of ΛCDM cosmology concerns the scale that separates these limits: the turnaround radius, which is the non-expanding shell furthest away from the center of a bound structure. We show that the maximum possible value of the turnaround radius within the framework of the ΛCDM model is, for a given mass M, equal to (3GM/Λ c{sup 2}){sup 1/3}, with G Newton's constant and c the speed of light, independently of cosmic epoch, exact nature of dark matter, or baryonic effects. We discuss the possible use of this prediction as an observational test for ΛCDM cosmology. Current data appear to favor ΛCDM over alternatives with local inhomogeneities and no Λ. However there exist several local-universe structures that have, within errors, reached their limiting size. With improved determinations of their turnaround radii and the enclosed mass, these objects may challenge the limit and ΛCDM cosmology.

Examining the impacts of Feed-in-Tariff and the Clean Development Mechanism on Korea's renewable energy projects through comparative investment analysis

International Nuclear Information System (INIS)

Koo, Bonsang

2017-01-01

Renewable energy projects in Korea have two avenues that provide subsidies to increase their financial viability. Feed-in-Tariffs (FITs) offer cost based prices for renewable electricity to compete with conventional energy producers. The Clean Development Mechanism (CDM) issues certified emission reduction (CER) credits that generate additional revenues, enhancing renewable projects’ return on investment. This study investigated how these subsidies impact the financial returns on Korea's CDM projects. An investment analysis was performed on four cases including solar, hydropower, wind and landfill gas projects. Revenues from electricity sales, FITs and CERs were compared using financial indicators to measure their relative contributions on profitability. Results indicate that CDM is partial towards large scale projects with high emission reductions. Moreover, conflicts with FIT schemes can deter small scale, capital intensive projects from pursuing registration. The analysis highlights CDM's bias for particular project types, which is in part due to its impartiality towards carbon credit prices. It also reveals that Korea, a key benefactor of CDM, is susceptible to such biases, as demonstrated by the disproportionate distribution of issued CERs. Improving incentives for bundled, small scale projects, CER price differentiation, and excluding domestic subsidies during additionality testing are proposed as possible reforms. - Highlights: • Korea constitute 8.2% of total CERs issued, third largest in the world after China and India. • CDM favors commercially competitive projects of large scale and high emissions. • 91% of issued CERs from GWP gas; of renewables, 88% from landfill gas and wind. • CER revenues marginal for small scale, commercially less attractive projects. • Conflicts with FIT potentially deters small scale projects from registration.

The report is intended to be a guidance document for project developers, investors, lenders, and CDM host countries involved in wind power projects in the CDM. The report explores in particular those issues that are important in CDM project assessment and development - that is, baseline development, carbon financing, and environmental sustainability. It does not deal in detail with those issues that are routinely covered in a standard wind power project assessment. The report tests, compares, and recommends methodologies for and approaches to baseline development. To present the application and implications of the various methodologies and approaches in a concrete context, Africa's largest wind farm-namely the 60 MW wind farm located in Zafarana, Egypt- is examined as a hypothetical CDM wind power project The report shows that for the present case example there is a difference of about 25% between the lowest (0.5496 tCO2/MWh) and the highest emission rate (0.6868 tCO 2 /MWh) estimated in accordance with these three standardized approaches to baseline development according to the Marrakesh Accord. This difference in emission factors comes about partly as a result of including hydroelectric power in the baseline scenario. Hydroelectric resources constitute around 21% of the generation capacity in Egypt, and, if excluding hydropower, the difference between the lowest and the highest baseline is reduced to 18%. Furthermore, since the two variations of the 'historical' baseline option examined result in the highest and the lowest baselines, by disregarding this baseline option altogether the difference between the lowest and the highest is reduced to 16%. The ES3-model, which the Systems Analysis Department at Risoe National Laboratory has developed, makes it possible for this report to explore the project-specific approach to baseline development in some detail. Based on quite disaggregated data on the Egyptian electricity system, including the wind power production

This paper aims at quantifying the impact of government policy and clean development mechanism (CDM) on wind power development in China. Firstly we review the background of Chinese wind power development and policy, as well as literature of climate change and CDM. We then present methodology, scenarios and data of a case study for the development of a large-scale grid-connected wind farm. We undertake project financial analysis under three scenarios. Our analysis results show that the project FIRR is 8.31% if CDM benefit is not taken into account, 8.72% if CDM benefit is considered with the price of the certified emission reduction (CER) at US dollars 4, and 10.28% if both the CDM benefit and government policy on cutting value added tax (VAT) by 50% are taken into account. This paper concludes that CDM and government preferential policy on value added tax will make wind power development financially viable in China. (author)

Simultaneous falsification of ΛCDM and quintessence with massive, distant clusters

International Nuclear Information System (INIS)

Mortonson, Michael J.; Hu, Wayne; Huterer, Dragan

2011-01-01

Observation of even a single massive cluster, especially at high redshift, can falsify the standard cosmological framework consisting of a cosmological constant and cold dark matter (ΛCDM) with Gaussian initial conditions by exposing an inconsistency between the well-measured expansion history and the growth of structure it predicts. Through a likelihood analysis of current cosmological data that constrain the expansion history, we show that the ΛCDM upper limits on the expected number of massive, distant clusters are nearly identical to limits predicted by all quintessence models where dark energy is a minimally coupled scalar field with a canonical kinetic term. We provide convenient fitting formulas for the confidence level at which the observation of a cluster of mass M at redshift z can falsify ΛCDM and quintessence given cosmological parameter uncertainties and sample variance, as well as for the expected number of such clusters in the light cone and the Eddington bias factor that must be applied to observed masses. By our conservative confidence criteria, which equivalently require masses 3 times larger than typically expected in surveys of a few hundred square degrees, none of the presently known clusters falsify these models. Various systematic errors, including uncertainties in the form of the mass function and differences between supernova light curve fitters, typically shift the exclusion curves by less than 10% in mass, making current statistical and systematic uncertainties in cluster mass determination the most critical factor in assessing falsification of ΛCDM and quintessence.

The Clean Development Mechanism (CDM) of the Kyoto Protocol which allows for trade in emission reductions between developing and developed countries has a specific aim of ensuring that carbon emission reduction projects contribute to sustainable development of the host country according to standards set by that country. However, the development potential of transactions under the CDM is constrained by a number of factors. Governments face the dilemma of setting demanding sustainable development criteria and running the risk of losing investments to other developing countries with less demanding standards, or setting less stringent standards and thus generating little benefit at the local level. This is compounded by the fact that concluding deals under the CDM in developing countries is more expensive, time-consuming and risky than buying carbon credits elsewhere.

It is decided in the COP4 that the concrete schemes for the (Kyoto Mechanism) should be boiled down towards the end of 2000. Of the many outstanding issues concerned, those related to the clean development mechanism (CDM) involve a number of problems awaiting solution. In particular, setting the baselines for amounts of the greenhouse effect gas emissions in projects not existing, which are essential for identifying reduced amounts of emissions (or credits), poses serious difficulty because of wide arbitrariness involved in the methodology. Therefore, (standardization) of the procedures is demanded for the accurate identification. In actuality, however, no methodology has been established as to what methods will be possibly applicable to widely diversified types of projects. This workshop, therefore, has focused the discussions on the (baseline problems), expecting to serve as a trigger for the future directions by presenting international researches and promoting the discussions thereon to deepen recognition of these problems, where the AIJ experiences have served as one of the bases.

The e7 guide to implementing projects under the Clean Development Mechanism

International Nuclear Information System (INIS)

2003-09-01

The e7 was formed in 1992 to play an active role in global electricity issues and to promote sustainable development. It consists of nine leading electricity companies: American Electric Power (United States), Electricite de France (France), ENEL (Italy), Hydro-Quebec (Canada), The Kansai Electric Power Company, Inc. (Japan), Ontario Power Generation, Inc. (Canada), RWE (Germany), ScottishPower (United Kingdom), and Tokyo Electric Power Company (Japan). This report provides a guide to help develop projects under the Clean Development Mechanism (CDM), which is an instrument that allows public or private entities to invest in greenhouse gas (GHG) mitigating activities in developing countries and earn credits in an emission trading system. The dual objectives of the CDM, one of three mechanisms set out in the Kyoto Protocol, are the reduction of global GHG emissions and a contribution to sustainable development in the host country. The guidelines and procedures detailed by the United Nations Framework Convention on Climate Change (UN FCCC) and the related Protocols and Accords, were followed in the preparation of this document. Recommendations based on e7 experience were also included. The criteria for success were stated, and additionality was discussed. Additionality refers to the reductions of emissions that are additional to any that would occur in the absence of the certified project activity. The baseline methodology was described. Project Design Document (PDD) is the format that must be used for presenting the information pertaining to a project and its evaluation. PDD contents include: general description of the project activity, baseline methodology, identification of crediting period, monitoring methodology and plan, calculation of GHG emissions by sources, environmental impacts, and stakeholder comments. Third party verification, and project risk and transaction costs were also addressed. refs., tabs., figs

The aim of the present paper is to investigate the prospects for the exploitation of the Kyoto Protocol's Clean Development Mechanism (CDM) in Greece. The paper is addressing 3 questions: in which country, what kind of investment, with which economic and environmental return? The proposed approach is based on a multicriteria analysis for identifying priority countries and interesting investment opportunities in each priority country. These opportunities are then evaluated through a conventional financial analysis in order to assess their economic and environmental attractiveness. To this purpose, the IRR of a typical project in each investment category is calculated by taking into account country-specific parameters, such as baseline emission factors, load factors, costs, energy prices etc. The results reveal substantial differences in the economic and environmental return of different types of projects in different host-countries and show that for the full exploitation of the CDM a multifaceted approach to decision-making is necessary

The Most Massive Galaxies and Black Holes Allowed by ΛCDM

Given a galaxy's stellar mass, its host halo mass has a lower limit from the cosmic baryon fraction and known baryonic physics. At z > 4, galaxy stellar mass functions place lower limits on halo number densities that approach expected ΛCDM halo mass functions. High-redshift galaxy stellar mass functions can thus place interesting limits on number densities of massive haloes, which are otherwise very difficult to measure. Although halo mass functions at z function of redshift given expected halo number densities from ΛCDM. We apply similar arguments to black holes. If their virial mass estimates are accurate, number density constraints alone suggest that the quasars SDSS J1044-0125 and SDSS J010013.02+280225.8 likely have black hole mass — stellar mass ratios higher than the median z = 0 relation, confirming the expectation from Lauer bias. Finally, we present a public code to evaluate the probability of an apparently ΛCDM-inconsistent high-mass halo being detected given the combined effects of multiple surveys and observational errors.

Λ CDM is Consistent with SPARC Radial Acceleration Relation

Recent analysis of the Spitzer Photometry and Accurate Rotation Curve (SPARC) galaxy sample found a surprisingly tight relation between the radial acceleration inferred from the rotation curves and the acceleration due to the baryonic components of the disk. It has been suggested that this relation may be evidence for new physics, beyond Λ CDM . In this Letter, we show that 32 galaxies from the MUGS2 match the SPARC acceleration relation. These cosmological simulations of star-forming, rotationally supported disks were simulated with a WMAP3 Λ CDM cosmology, and match the SPARC acceleration relation with less scatter than the observational data. These results show that this acceleration relation is a consequence of dissipative collapse of baryons, rather than being evidence for exotic dark-sector physics or new dynamical laws.

A real option-based model to valuate CDM projects under uncertain energy policies for emission trading

Highlights: • A real option-based model for the valuation of CDM projects is proposed. • This study investigates the impact of energy policies on the value of CDM projects. • Level of target emission and its schedule should be carefully designed. • Government subsidy facilitates the implementation of CDM projects. • Period for free emission allowance prevents promoting CDM projects. - Abstract: Emission trading has been considered a primary policy tool for emission reduction. Governments establish national targets for emission reduction and assign emission reduction goals to private entities to accomplish the targets. To attain the goal, private entities should perform offset projects that can produce emission credits or buy emission credits from the market. However, it is not easy for private entities to decide to implement the projects because energy policies associated with emission trading keep changing; thus, the future benefits of the offset projects are quite uncertain. This study presents a real option-based model to investigate how uncertain energy policies affect the financial viability of an offset project. A case study showed that the establishment of a target emission was attractive to the government because it could make the CDM project financially viable with a small amount of government subsidy. In addition, the level of the government subsidy could determine the investment timing for the CDM project. In this context, governments should be cautious in designing energy policies, because even the same energy policies could have different impacts on private entities. Overall, this study is expected to assist private entities in establishing proper investment strategies for CDM projects under uncertain energy policies

This paper presents the theoretical investigation of CDM opportunity in a township at Jaipur, India. The purpose of study is to identify and analyze the various opportunities viz., installation of solar water heater, energy efficient lighting, energy efficient air conditioners, and energy efficient submersible water pumps in desert coolers and thus achieve a considerable (65.7 %) reduction in GHG emissions. Out of the various opportunities considered, the retrofitting with solar water heater can be recommended for CDM. Though, the retrofitting with energy efficient lighting, energy efficient air conditioners and energy efficient submersible water pumps in desert coolers claimed CO2 emission reduction of 104.84, 25.92, and 36.94 tons per annum, respectively, but the only opportunity which got through CDM was retrofitting with solar water heater claiming 115.70 tCO2 (100 %) emission reductions per annum which could result into net earnings of 115.70 CERs. The simple and discounted payback period for all four project activities are also calculated with and without CDM and tax benefits.

It is well known that a canonical scalar field is able to describe either dark matter or dark energy but not both. We demonstrate that a non-canonical scalar field can describe both dark matter and dark energy within a unified setting. We consider the simplest extension of the canonical Lagrangian L ∝ X"α - V(φ) where α ≥ 1 and V is a sufficiently flat potential. In this case the kinetic term in the Lagrangian behaves just like a perfect fluid, whereas the potential term mimicks dark energy. For very large values, α >> 1, the equation of state of the kinetic term drops to zero and the universe expands as if filled with a mixture of dark matter and dark energy. The velocity of sound in this model and the associated gravitational clustering are sensitive to the value of α. For very large values of α the clustering properties of our model resemble those of cold dark matter (CDM). But for smaller values of α, gravitational clustering on small scales is suppressed, and our model has properties resembling those of warm dark matter (WDM). Therefore our non-canonical model has an interesting new property: its expansion history resembles Λ CDM, while its clustering properties are akin to those of either cold or warm dark matter.

How to falsify the GR+ΛCDM model with galaxy redshift surveys

International Nuclear Information System (INIS)

Acquaviva, Viviana; Gawiser, Eric

2010-01-01

A wide range of models describing modifications to general relativity have been proposed, but no fundamental parameter set exists to describe them. Similarly, no fundamental theory exists for dark energy to parametrize its potential deviation from a cosmological constant. This motivates a model-independent search for deviations from the concordance GR+ΛCDM cosmological model in large galaxy redshift surveys. We describe two model-independent tests of the growth of cosmological structure, in the form of quantities that must equal one if GR+ΛCDM is correct. The first, ε, was introduced previously as a scale-independent consistency check between the expansion history and structure growth. The second, υ, is introduced here as a test of scale-dependence in the linear evolution of matter density perturbations. We show that the ongoing and near-future galaxy redshift surveys WiggleZ, BOSS, and HETDEX will constrain these quantities at the 5-10% level, representing a stringent test of concordance cosmology at different redshifts. When redshift space distortions are used to probe the growth of cosmological structure, galaxies at higher redshift with lower bias are found to be most powerful in detecting the presence of deviations from the GR+ΛCDM model. However, because many dark energy or modified gravity models predict consistency with GR+ΛCDM at high redshift, it is desirable to apply this approach to surveys covering a wide range of redshifts and spatial scales.

Small Scale Problems of the ΛCDM Model: A Short Review

Directory of Open Access Journals (Sweden)

Antonino Del Popolo

2017-02-01

Full Text Available The ΛCDM model, or concordance cosmology, as it is often called, is a paradigm at its maturity. It is clearly able to describe the universe at large scale, even if some issues remain open, such as the cosmological constant problem, the small-scale problems in galaxy formation, or the unexplained anomalies in the CMB. ΛCDM clearly shows difficulty at small scales, which could be related to our scant understanding, from the nature of dark matter to that of gravity; or to the role of baryon physics, which is not well understood and implemented in simulation codes or in semi-analytic models. At this stage, it is of fundamental importance to understand whether the problems encountered by the ΛDCM model are a sign of its limits or a sign of our failures in getting the finer details right. In the present paper, we will review the small-scale problems of the ΛCDM model, and we will discuss the proposed solutions and to what extent they are able to give us a theory accurately describing the phenomena in the complete range of scale of the observed universe.

Stochastic backgrounds of relic gravitons, T$\\Lambda$CDM paradigm and the stiff ages

Absent any indirect tests on the thermal history of the Universe prior to the formation of light nuclear elements, it is legitimate to investigate situations where, before nucleosyntheis, the sound speed of the plasma was larger than $c/\\sqrt{3}$, at most equalling the speed of light $c$. In this plausible extension of the current cosmological paradigm, hereby dubbed Tensor-$\\Lambda$CDM (i.e. T$\\Lambda$CDM) scenario, high-frequency gravitons are copiously produced. Without conflicting with the bounds on the tensor to scalar ratio stemming from the combined analysis of the three standard cosmological data sets (i.e. cosmic microwave background anisotropies, large-scale structure and supenovae), the spectral energy density of the relic gravitons in the T$\\Lambda$CDM scenario can be potentially observable by wide-band interferometers (in their advanced version) operating in a frequency window which ranges between few Hz and few kHz.

Can f(T) gravity theories mimic ΛCDM cosmic history

Recently the teleparallel Lagrangian density described by the torsion scalar T has been extended to a function of T. The f(T) modified teleparallel gravity has been proposed as the natural gravitational alternative for dark energy to explain the late time acceleration of the universe. In order to reconstruct the function f(T) by demanding a background ΛCDM cosmology we assume that, (i) the background cosmic history provided by the flat ΛCDM (the radiation ere with ω{sub eff} = (1/3), matter and de Sitter eras with ω{sub eff} = 0 and ω{sub eff} = −1, respectively) (ii) the radiation dominate in the radiation era with Ω{sub 0r} = 1 and the matter dominate during the matter phases when Ω{sub 0m} = 1. We find the cosmological dynamical system which can obey the ΛCDM cosmic history. In each era, we find a critical lines that, the radiation dominated and the matter dominated are one points of them in the radiation and matter phases, respectively. Also, we drive the cosmologically viability condition for these models. We investigate the stability condition with respect to the homogeneous scalar perturbations in each era and we obtain the stability conditions for the fixed points in each eras. Finally, we reconstruct the function f(T) which mimics cosmic expansion history.

The newly released observational H(z) data (OHD) is used to constrain Λ(t)CDM models as holographic and agegraphic dark energy. By the use of the length scale and time scale as the IR cut-off including Hubble horizon (HH), future event horizon (FEH), age of the universe (AU), and conformal time (CT), we achieve four different Λ(t)CDM models which can describe the present cosmological acceleration respectively. In order to get a comparison between such Λ(t)CDM models and standard ΛCDM model, we use the information criteria (IC), Om(z) diagnostic, and statefinder diagnostic to measure the deviations. Furthermore, by simulating a larger Hubble parameter data sample in the redshift range of 0.1 < z < 2.0, we get the improved constraints and more sufficient comparison. We show that OHD is not only able to play almost the same role in constraining cosmological parameters as SNe Ia does but also provides the effective measurement of the deviation of the DE models from standard ΛCDM model. In the holographic and agegraphic scenarios, the results indicate that the FEH is more preferable than HH scenario. However, both two time scenarios show better approximations to ΛCDM model than the length scenarios.

Distinguishing CDM dwarfs from SIDM dwarfs in baryonic simulations

Science.gov (United States)

Strickland, Emily; Fitts, Alex B.; Boylan-Kolchin, Michael

2017-06-01

Dwarf galaxies in the nearby Universe are the most dark-matter-dominated systems known. They are therefore natural probes of the nature of dark matter, which remains unknown. Our collaboration has performed several high-resolution cosmological zoom-in simulations of isolated dwarf galaxies. We simulate each galaxy in standard cold dark matter (ΛCDM) as well as self-interacting dark matter (SIDM, with a cross section of σ/m ~ 1 cm2/g), both with and without baryons, in order to identify distinguishing characteristics between the two. The simulations are run using GIZMO, a meshless-finite-mass hydrodynamical code, and are part of the Feedback in Realistic Environments (FIRE) project. By analyzing both the global properties and inner structure of the dwarfs in varying dark matter prescriptions, we provide a side-by-side comparison of isolated, dark-matter-dominated galaxies at the mass scale where differences in the two models of dark matter are thought to be the most obvious. We find that the edge of classical dwarfs and ultra-faint dwarfs (at stellar masses of ~105 solar masses) provides the clearest window for distinguishing between the two theories. At these low masses, our SIDM galaxies have a cored inner density profile, while their CDM counterparts have “cuspy” centers. The SIDM versions of each galaxy also have measurably lower stellar velocity dispersions than their CDM counterparts. Future observations of ultra faint dwarfs with JWST and 30-m telescopes will be able to discern whether such alternate theories of dark matter are viable.

Dynamics of technology shifts in the household sector-implications for clean development mechanism

2006-01-01

The present paper attempts to analyse the dynamics of energy end-use technology shifts in the household sector in India. The technology shifts can be categorized as naturally occurring shifts (with increasing household incomes and availability of energy carriers) and policy-induced shifts (by creating a favourable environment). Initially, the households energy usage patterns, types of energy carriers and the technologies in use are analysed using the data from the National Sample Survey (1999-2000). The energy consumption is disaggregated according to end-use activity and by income groups for rural as well as urban households. It is observed that large variations in energy use exist across different sections of households-urban/rural, low/high-income groups, etc. Further, the paper provides a methodological framework for the diffusion of energy-efficient technologies, and the implications of such diffusions for the Clean Development Mechanism (CDM). It analyses the reasons for the gap between possible and practical implementation of energy-efficient measures, study the reasons for households not using the cost-effective technologies available to them, the benefits of innovation of energy efficiency, and the required policies and specific proposals for government intervention to achieve the potential for the CDM

Through a cross-sectional survey of different stakeholder groups, the prospective sustainable development criteria for the CDM are examined and prospective small-scale CDM projects are analysed. One efficient option to reduce transaction costs to small scale CDM projects is the creation of a regional centre for capacity building and project pre-validation. This study analyses how the WAEMU could be used as a vehicle to attract CDM financing. (orig.)

La abundancia de galaxias y halos de materia oscura en el universo CDM

Science.gov (United States)

Abadi, M. G.; Benítez-Llambay, A.; Ferrero, I.

A long-standing puzzle of CDM cosmological model concerns to the different shape of the galaxy stellar mass function and the halo mass function on dwarf galaxy scales. Dwarf galaxies are much less numerous than halos massive enough to host them; suggesting a complex non-linear relation between the mass of a galaxy and the mass of its surrounding halo. Usually; this is reconciled by appealing to baryonic processes that can reduce the efficiency of galaxy formation in low-mass halos. Recent work applying the abundance matching technique require that virtually no dwarf galaxies form in halos with virial mass below . We use rotation curves of dwarf galaxies compiled from the literature to explore whether their total enclosed mass is consistent with these constraints. Almost one-half of the dwarfs in our sample are at odds with this restriction; they are in halos with masses substantially below . Using a cosmological simulation of the formation of the Local Group of galaxies we found that ram-pressure stripping against the cosmic web removes baryons from low-mass halos without appealing to feedback or reionization. This mechanism may help to explain the scarcity of dwarf galaxies compared with the numerous low-mass halos expected in CDM and the large diversity of star formation histories and morphologies characteristic of faint galaxies.

Gravitational wave memory in ΛCDM cosmology

We examine gravitational wave memory in the case where sources and detector are in a ΛCDM cosmology. We consider the case where the Universe can be highly inhomogeneous, but gravitational radiation is treated in the short wavelength approximation. We find results very similar to those of gravitational wave memory in an asymptotically flat spacetime; however, the overall magnitude of the memory effect is enhanced by a redshift-dependent factor. In addition, we find the memory can be affected by lensing. (paper)

The Brazil/US Aspen Global Forum on Climate Change Policies and Programs has facilitated a dialogue between key Brazil and US public and private sector leaders on the subject of the Clean Development Mechanism (CDM). With support from the US government, a cooperative effort between Lawrence Berkeley National Laboratory and the University of Sao Paulo conducted an assessment of a number of projects put forth by Brazilian sponsors. Initially, we gathered information and conducted a screening assessment for ten projects in the energy sector and six projects in the forestry sector. Some of the projects appeared to offer greater potential to be attractive for CDM, or had better information available. We then conducted a more detailed assessment of 12 of these projects, and two other projects that were submitted after the initial screening. An important goal was to assess the potential impact of Certified Emission Reductions (CERs) on the financial performance of projects. With the exception of the two forestry-based fuel displacement projects, the impact of CERs on the internal rate of return (IRR) is fairly small. This is true for both the projects that displace grid electricity and those that displace local (diesel-based) electricity production. The relative effect of CERs is greater for projects whose IRR without CERs is low. CERs have a substantial effect on the IRR of the two short-rotation forestry energy substitution projects. One reason is that the biofuel displaces coke and oil, both of which are carbon-intensive. Another factor is that the product of these projects (charcoal and woodfuel, respectively) is relatively low value, so the revenue from carbon credits has a strong relative impact. CERs also have a substantial effect on the NPV of the carbon sequestration projects. Financial and other barriers pose a challenge for implementation of most of the projects. In most cases, the sponsor lacks sufficient capital, and loans are available only at high interest

The world-wide necessity of greenhouse gases mitigation and the intergovernmental mobilization to reach the objectives established by the United Nations Framework on Climate Change (UNFCCC) has opened space for the renewable energy increase in the world's energy matrix. In Brazil, the solid sugarcane industry currently develops business in the scope of the clean development mechanism (CDM) under the Kyoto's Protocol, by means of 18 biomass-based projects, with renewable energy generation through bagasse cogeneration at 20 Sao Paulo State's sugarcane production units. The projects activity's consists of increasing the efficiency in the bagasse cogeneration facilities, qualifying the units to sell surplus electricity to the national grid, avoiding the dispatch of the same amount of energy produced by fossil-fuelled thermal plants to that grid. The reduced emissions are measured in carbon equivalent and can be converted into negotiable credits. The objective of this study was to build a 'state of art' scenario, calculating the potential emissions reduction through CDM projects for the sugarcane sector of Sao Paulo State, in which we consider the adherence of all the production units of the State to the CDM projects. The technological parameters used to elaborate the scenario were provided by the Sao Paulo State Government Bioenergy Special Commission and the baseline factor used of 0,268 tCO{sub 2}e/MWh was the adopted by the CDM projects in operation in the State. The sugarcane database for the calculations was the production ranking provided by UNICA for the 2006/2007 season. In the most conservative scenario (40 bar bagasse) 131 units could generate 607 MWm of surplus power avoiding the emission of 1.404.593 tCO{sub 2}e/year. For the 92 bar (bagasse and straw) scenario, the units could generate 3.055 MWm of surplus power avoiding 12.199.443 tCO{sub 2}e/year. (author)

Conformal coupling associated with the Noether symmetry and its connection with the ΛCDM dynamics

The aim of this work is to investigate a non-minimally coupled scalar field model through the Noether symmetry approach, with the radiation, matter and cosmological constant eras being analyzed. The Noether symmetry condition allows a conformal coupling and by means of a change of coordinates in the configuration space the field equations can be reduced to a single equation, which is of the form of the Friedmann equation for the ΛCDM model. In this way, it is formally shown that the dynamical system can furnish solutions with the same form as those of the ΛCDM model, although the theory here considered is physically different from the former. The conserved quantity associated with the Noether symmetry can be related to the kinetic term of the scalar field and could constrain the possible deviations of the model from the ΛCDM picture. Observational constraints on the variation of the gravitational constant can be imposed on the model through the initial condition of the scalar field. (paper)

Impact of the Clean Development Mechanism on wind energy investments in Turkey

As carbon trading continues to be implemented on both a national and an international scale, it is becoming an important factor in renewable energy investment decisions. Turkey, with continuous growth of carbon dioxide emission and energy consumption since 2001, ratified the Kyoto Protocol in 2009 and began registration of projects with greenhouse gas reductions in 2010. In light of these developments, wind energy resources with a potential of 48,000 MW are among the most efficient and effective solutions for clean and sustainable energy in Turkey. The aim of our study is to reveal the importance of the Clean Development Mechanism (CDM) of the Kyoto Protocol on wind energy investment decisions. A broad review of wind energy in Turkey is given, and then, a comprehensive feasibility study of a wind energy firm with a valuation model including Certified Emission Reduction (CER) prices is applied to a case study, the Mega Metallurgy Power. With a holistic and interdisciplinary system engineering approach, results are obtained using comprehensive analysis of technology, emission, and power generation of a wind energy firm linked to a valuation model. This comprehensive model sets the investment decision-making criteria, the enterprise value comparison with total financing. Finally, a sensitivity analysis is run to show that the enterprise value is positively correlated with CER prices. Based on these results, it is concluded that if the world's largest carbon offsetting program, the CDM, prevails after 2012, CER prices will have a positive impact on wind energy firm valuations and related investment decisions.

Consistency of ΛCDM with geometric and dynamical probes

International Nuclear Information System (INIS)

Perivolaropoulos, L

2010-01-01

The ΛCDM cosmological model assumes the existence of a small cosmological constant in order to explain the observed accelerating cosmic expansion. Despite the dramatic improvement of the quality of cosmological data during the last decade it remains the simplest model that fits remarkably well (almost) all cosmological observations. In this talk I review the increasingly successful fits provided by ΛCDM on recent geometric probe data of the cosmic expansion. I also briefly discuss some emerging shortcomings of the model in attempting to fit specific classes of data (eg cosmic velocity dipole flows and cluster halo profiles). Finally, I summarize recent results on the theoretically predicted matter overdensity (δ m =(δρ m )/ρ m ) evolution (a dynamical probe of the cosmic expansion), emphasizing its scale and gauge dependence on large cosmological scales in the context of general relativity. A new scale dependent parametrization which describes accurately the growth rate of perturbations even on scales larger than 100h -1 Mpc is shown to be a straightforward generalization of the well known scale independent parametrization f(a) = Ω m (a) γ valid on smaller cosmological scales.

Gamma-ray bursts as cosmological probes: ΛCDM vs. conformal gravity

International Nuclear Information System (INIS)

Diaferio, Antonaldo; Ostorero, Luisa; Cardone, Vincenzo

2011-01-01

ΛCDM, for the currently preferred cosmological density Ω 0 and cosmological constant Ω Λ , predicts that the Universe expansion decelerates from early times to redshift z ≈ 0.9 and accelerates at later times. On the contrary, the cosmological model based on conformal gravity predicts that the cosmic expansion has always been accelerating. To distinguish between these two very different cosmologies, we resort to gamma-ray bursts (GRBs), which have been suggested to probe the Universe expansion history at z > 1, where identified type Ia supernovae (SNe) are rare. We use the full Bayesian approach to infer the cosmological parameters and the additional parameters required to describe the GRB data available in the literature. For the first time, we use GRBs as cosmological probes without any prior information from other data. In addition, when we combine the GRB samples with SNe, our approach neatly avoids all the inconsistencies of most numerous previous methods that are plagued by the so-called circularity problem. In fact, when analyzed properly, current data are consistent with distance moduli of GRBs and SNe that can respectively be, in a variant of conformal gravity, ∼ 15 and ∼ 3 magnitudes fainter than in ΛCDM. Our results indicate that the currently available SN and GRB samples are accommodated equally well by both ΛCDM and conformal gravity and do not exclude a continuous accelerated expansion. We conclude that GRBs are currently far from being effective cosmological probes, as they are unable to distinguish between these two very different expansion histories

We present a method that extends the capabilities of the PINpointing Orbit-Crossing Collapsed HIerarchical Objects (PINOCCHIO) code, allowing it to generate accurate dark matter halo mock catalogues in cosmological models where the linear growth factor and the growth rate depend on scale. Such cosmologies comprise, among others, models with massive neutrinos and some classes of modified gravity theories. We validate the code by comparing the halo properties from PINOCCHIO against N-body simulations, focusing on cosmologies with massive neutrinos: νΛCDM. We analyse the halo mass function, halo two-point correlation function and halo power spectrum, showing that PINOCCHIO reproduces the results from simulations with the same level of precision as the original code (∼ 5–10%). We demonstrate that the abundance of halos in cosmologies with massless and massive neutrinos from PINOCCHIO matches very well the outcome of simulations, and point out that PINOCCHIO can reproduce the Ω{sub ν}–σ{sub 8} degeneracy that affects the halo mass function. We finally show that the clustering properties of the halos from PINOCCHIO matches accurately those from simulations both in real and redshift-space, in the latter case up to k = 0.3 h Mpc{sup −1}. We emphasize that the computational time required by PINOCCHIO to generate mock halo catalogues is orders of magnitude lower than the one needed for N-body simulations. This makes this tool ideal for applications like covariance matrix studies within the standard ΛCDM model but also in cosmologies with massive neutrinos or some modified gravity theories.

On September 24-25 1999, CIRED and RFF held a workshop at CIRED to explore a number of key policy issues surrounding the design and operation of the Clean Development Mechanism (CDM). This mechanism, created as part of the 1997 Kyoto Protocol to the United Nations Framework Convention on Climate Change (FCCC), has been the subject of much ongoing negotiation and debate. The multinational participants assembled not to seek consensus but to promote better understanding of commonalties and differences in views in a non politicized setting, as well as to see what new ideas and understandings might emerge from the discussions. The meetings were informal and ''off the record'' to promote frank exchange. This document is a summary of the discussions as seen through the eyes of the two co-organizers. We have tried to reflect as well as possible the range and diversity of the thoughts expressed at the meeting, and we have circulated this summary to other participants for their comments. But we alone are responsible for its content. (author)

Non-parametric reconstruction methods, such as Gaussian process (GP) regression, provide a model-independent way of estimating an underlying function and its uncertainty from noisy data. We demonstrate how GP-reconstruction can be used as a consistency test between a given data set and a specific model by looking for structures in the residuals of the data with respect to the model's best-fit. Applying this formalism to the Planck temperature and polarisation power spectrum measurements, we test their global consistency with the predictions of the base ΛCDM model. Our results do not show any serious inconsistencies, lending further support to the interpretation of the base ΛCDM model as cosmology's gold standard.

Bagasse power generation projects provide a useful framework for evaluating several key aspects of the Clean Development Mechanism of the Kyoto Protocol. On the positive side, our analysis, which draws in part from a data set of 204 bagasse electricity generation projects at sugar mills, indicates that these projects provide Annex I country investors with a cost-effective means to achieve greenhouse gas emissions reductions. Our analysis also confirms that the marketplace for Clean Development Mechanism-derived offsets is robust and competitive. Moreover, bagasse projects appear to provide a positive example in a 'new wave' of clean energy investment that has replaced the earlier industrial gas projects. At the same time, we also identify two aspects of the CDM that demand improvement. First, the additionality standard needs to be tightened and made more transparent and consistent. Financial additionality should be required for all projects; however, any financial additionality test applied by the Clean Development Mechanism's Executive Board must be informed by the significant barriers faced by many projects. Second, the administrative processes for registration and verification of offsets need to be streamlined in order to prevent long registration time lags from chilling clean energy investment.

Leading global energy and environmental transformation: Unified ASEAN biomass-based bio-energy system incorporating the clean development mechanism

International Nuclear Information System (INIS)

Lim, Steven; Lee, Keat Teong

2011-01-01

In recent years, the ten member countries in the Association of Southeast Asia Nations (ASEAN) have experienced high economic growth and, in tandem, a substantial increment in energy usage and demand. Consequently, they are now under intense pressure to secure reliable energy supplies to keep up with their growth rate. Fossil fuels remain the primary source of energy for the ASEAN countries, due to economic and physical considerations. This situation has led to unrestrained emissions of greenhouse gases to the environment and thus effectively contributes to global climate change. The abundant supply of biomass from their tropical environmental conditions offers great potential for ASEAN countries to achieve self-reliance in energy supplies. This fact can simultaneously transform into the main driving force behind combating global climate change, which is associated with the usage of fossil fuels. This research article explores the potential and advantages for ASEAN investment in biomass-based bio-energy supply, processing and distribution network with an emphasis on regional collaborations. It also investigates the implementation and operational challenges in terms of political, economic and technical factors for the cross-border energy scheme. Reliance of ASEAN countries on the clean development mechanism (CDM) to address most of the impediments in developing the project is also under scrutiny. Unified co-operation among ASEAN countries in integrating biomass-based bio-energy systems and utilising the clean development mechanism (CDM) as the common effort could serve as the prime example for regional partnerships in achieving sustainable development for the energy and environmental sector in the future. -- Highlights: →A study that explores feasibility for ASEAN investment in biomass-based bio-energy. →Focus is given on regional supply, processing and distribution network. →Cross-border implementation and operational challenges are discussed thoroughly.

The main findings of two high-level regional workshops organized in 2002 - by the International Petroleum Industry Environmental Conservation Association (IPIECA) in Kuala Lumpur, Malaysia, and by the Regional Association of Oil and Natural Gas Companies in Latin America and the Caribbean (ARPEL), IPIECA and UNEP in San Jose, Costa Rica - are presented in this article. The purpose of these workshops was to increase the understanding of regional development and climate change issues, and to identify opportunities for effective near- and long-term action, particularly through the Clean Development Mechanism (CDM). Economic, methodological and institutional barriers to private sector investment in CDM projects still exist. Uncertainties about rules surrounding the CDM have progressed from hypothetical concerns to more practical ones related to institutional capacity to review and approve project applications in a timely and cost-effective manner

Weak lensing cosmology beyond ΛCDM

Weak gravitational lensing is one of the key probes of the cosmological model, dark energy, and dark matter, providing insight into both the cosmic expansion history and large scale structure growth history. Taking into account a broad spectrum of physics affecting growth — dynamical dark energy, extended gravity, neutrino masses, and spatial curvature — we analyze the cosmological constraints. Similarly we consider the effects of a range of systematic uncertainties, in shear measurement, photometric redshifts, intrinsic alignments, and the nonlinear power spectrum, on cosmological parameter extraction. We also investigate, and provide fitting formulas for, the influence of survey parameters such as redshift depth, galaxy number densities, and sky area on the cosmological constraints in the beyond-ΛCDM parameter space. Finally, we examine the robustness of results for different fiducial cosmologies

The results of N-body simulations with both Gaussian and non-Gaussian initial conditions are used here to generate projected galaxy catalogs with the same selection criteria as the Shane-Wirtanen counts of galaxies. The Euler-Poincare characteristic is used to compare the statistical nature of the projected galaxy clustering in these simulated data sets with that of the observed galaxy catalog. All the models produce a topology dominated by a meatball shift when normalized to the known small-scale clustering properties of galaxies. Models characterized by a positive skewness of the distribution of primordial density perturbations are inconsistent with the Lick data, suggesting problems in reconciling models based on cosmic textures with observations. Gaussian CDM models fit the distribution of cell counts only if they have a rather high normalization but possess too low a coherence length compared with the Lick counts. This suggests that a CDM model with extra large scale power would probably fit the available data.

Confronting dark energy models mimicking ΛCDM epoch with observational constraints: Future cosmological perturbations decay or future Rip?

Astashenok, Artyom V.; Odintsov, Sergei D.

2013-01-01

We confront dark energy models which are currently similar to ΛCDM theory with observational data which include the SNe data, matter density perturbations and baryon acoustic oscillations data. DE cosmology under consideration may evolve to Big Rip, type II or type III future singularity, or to Little Rip or Pseudo-Rip universe. It is shown that matter perturbations data define more precisely the possible deviation from ΛCDM model than consideration of SNe data only. The combined data analysis proves that DE models under consideration are as consistent as ΛCDM model. We demonstrate that growth of matter density perturbations may occur at sufficiently small background density but still before the possible disintegration of bound objects (like clusters of galaxies, galaxies, etc.) in Big Rip, type III singularity, Little Rip or Pseudo-Rip universe. This new effect may bring the future universe to chaotic state well before disintegration or Rip.

It is increasingly necessary to generate medical evidence applicable to Asian people compared to those in Western countries. Observational Health Data Sciences a Informatics (OHDSI) is an international collaborative which aims to facilitate generating high-quality evidence via creating and applying open-source data analytic solutions to a large network of health databases across countries. We aimed to incorporate Korean nationwide cohort data into the OHDSI network by converting the national sample cohort into Observational Medical Outcomes Partnership-Common Data Model (OMOP-CDM). The data of 1.13 million subjects was converted to OMOP-CDM, resulting in average 99.1% conversion rate. The ACHILLES, open-source OMOP-CDM-based data profiling tool, was conducted on the converted database to visualize data-driven characterization and access the quality of data. The OMOP-CDM version of National Health Insurance Service-National Sample Cohort (NHIS-NSC) can be a valuable tool for multiple aspects of medical research by incorporation into the OHDSI research network.

Feasibility of Applying Clean Development Mechanism and GHGs Emission Reductions in the Gold Mining Industry: A Case of Thailand

Science.gov (United States)

Kittipongvises, Suthirat

2015-12-01

There is presently overwhelming scientific consensus that global climate change is indeed occurring, and that human activities are the primary driver. An increasingly resource and carbon constrained world will continue to pose formidable challenges to major industries, including mining. Understanding the implications of climate change mitigation for the mining industry, however, remains limited. This paper presents the results of a feasibility study on the implementation of a clean development mechanism and greenhouse gases (GHGs) emission reductions in the gold mining industry. It draws upon and extends the analysis of a case study conducted on gold mining operations in Thailand. The results from the case study indicated that total GHGs emissions by company A were approximately 36,886 tons carbon dioxide equivalents (tCO2e) per annual gold production capacity that meet the eligibility criteria for small-scaled clean development mechanism (CDM) projects. The electrostatic separation process was found to release the lowest amount of GHGs, whereas comminution (i.e. crushing and grinding) generated the highest GHGs emissions. By scope, the emission from purchased electricity (scope 2) is the most significant source.

Full Text Available There is presently overwhelming scientific consensus that global climate change is indeed occurring, and that human activities are the primary driver. An increasingly resource and carbon constrained world will continue to pose formidable challenges to major industries, including mining. Understanding the implications of climate change mitigation for the mining industry, however, remains limited. This paper presents the results of a feasibility study on the implementation of a clean development mechanism and greenhouse gases (GHGs emission reductions in the gold mining industry. It draws upon and extends the analysis of a case study conducted on gold mining operations in Thailand. The results from the case study indicated that total GHGs emissions by company A were approximately 36,886 tons carbon dioxide equivalents (tCO2e per annual gold production capacity that meet the eligibility criteria for small-scaled clean development mechanism (CDM projects. The electrostatic separation process was found to release the lowest amount of GHGs, whereas comminution (i.e. crushing and grinding generated the highest GHGs emissions. By scope, the emission from purchased electricity (scope 2 is the most significant source.

Reyes, Reinabelle; Gunn, J. E.; Mandelbaum, R.

We consider the question of the origin of the Tully-Fisher relation in LambdaCDM cosmology. Reproducing the observed tight relation between stellar masses and rotation velocities of disk galaxies presents a challenge for semi-analytical models and hydrodynamic simulations of galaxy formation. Here, our goal is to construct a suite of galaxy mass models that is fully consistent with observations, and that also reproduces the observed Tully-Fisher relation. We take advantage of a well-defined sample of disk galaxies in SDSS with measured rotation velocities (from long-slit spectroscopy of H-alpha), stellar bulge and disk profiles (from fits to SDSS images), and average dark matter halo masses (from stacked weak lensing of a larger, similarly-selected sample). The primary remaining freedom in the mass models come from the final dark matter halo profile (after contraction from baryon infall and, possibly, feedback) and the stellar IMF. We find that the observed velocities are reproduced by models with Kroupa IMF and NFW (i.e., unmodified) dark matter haloes for galaxies with stellar masses 10^9-10^10 M_sun. For higher stellar masses, models with contracted NFW haloes are favored. A scenario in which the amount of halo contraction varies with stellar mass is able to reproduce the observed Tully-Fisher relation over the full stellar mass range of our sample from 10^9 to 10^11 M_sun. We present this as a proof-of-concept for consistency between LambdaCDM and the Tully-Fisher relation.

Full Text Available Empty Fruit Bunch (EFB as a solid waste in Crude Palm Oil (CPO industry does not utilized yet as an alternative energy source to generate electricity. It is well known that use of solid wate (biomass as an energy source is part of the Clean Development Mechanism (CDM scheme due to direct reduction of Green House Gases (GHGs emission and provide a direct contribution to sustainable development. Utilization of EFB as a source of energy is very potential to be implemented in Aceh since this province has 25 CPO Mills at the moment which actively produce about 870,000 ton EFB per year. This study is subjected to evaluate the potency of electricity  from EFB theoretically by using primary data (survey data and secondary data. Potency of EFB and number of electricity produced from that EFB are estimated using primary data and direct combustion scenario, respectively. Calculation methods for emission reduction acieved are done by AMS-I.D: Renewable electricity generation to the grid and AMS-III.E: Methane emissions avoided from dumping at a solid waste disposal site. The result of this investigation shows that energy consumption in 25 CPO Mills is 45 GW(eh per year. Evidently, the number of energy/electricity which is potential to be produced by using 75% EFB is 1,047 GWh per year; so that the GHGs emission reduction up to 171,232.21 tCO2e per year.

On a Search for Hidden Photon CDM by a Multicathode Counter

International Nuclear Information System (INIS)

Petukhov, V. V.; Kopylov, A. V.; Orekhov, I. V.

2016-01-01

We report a new technique of a multicathode counter (MCC) developed to search for hidden photon (HP) cold dark matter (CDM) with a mass from 5 to 500 eV. The method is suggested in the assumption that HP-photon mixing causes emission of single electrons from a metal cathode if the mass of hidden photon m_γ_"′ is greater than a work function of the metal φ_W. The measured effect from HP should be dependent on φ_W and on the structure of electronic shells of the metal used as a cathode. Potentially this can be used for a verification of the results obtained. Some preliminary results for the upper limit for mixing parameter χ have been obtained for HP with a mass from 5 eV to 10 keV as a pure illustration of the potential of this technique. The efforts are continued to refine the procedure of data treatment and to improve the work of MCC. A new detector with a more developed design is under construction.

A COMPARATIVE ANALYSIS OF THE SUPERNOVA LEGACY SURVEY SAMPLE WITH ΛCDM AND THE Rh=ct UNIVERSE

Wei, Jun-Jie; Wu, Xue-Feng; Melia, Fulvio; Maier, Robert S.

2015-01-01

The use of Type Ia supernovae (SNe Ia) has thus far produced the most reliable measurement of the expansion history of the universe, suggesting that ΛCDM offers the best explanation for the redshift–luminosity distribution observed in these events. However, analysis of other kinds of sources, such as cosmic chronometers, gamma-ray bursts, and high-z quasars, conflicts with this conclusion, indicating instead that the constant expansion rate implied by the R h = ct universe is a better fit to the data. The central difficulty with the use of SNe Ia as standard candles is that one must optimize three or four nuisance parameters characterizing supernova (SN) luminosities simultaneously with the parameters of an expansion model. Hence, in comparing competing models, one must reduce the data independently for each. We carry out such a comparison of ΛCDM and the R h = ct universe using the SN Legacy Survey sample of 252 SN events, and show that each model fits its individually reduced data very well. However, since R h = ct has only one free parameter (the Hubble constant), it follows from a standard model selection technique that it is to be preferred over ΛCDM, the minimalist version of which has three (the Hubble constant, the scaled matter density, and either the spatial curvature constant or the dark energy equation-of-state parameter). We estimate using the Bayes Information Criterion that in a pairwise comparison, the likelihood of R h = ct is ∼90%, compared with only ∼10% for a minimalist form of ΛCDM, in which dark energy is simply a cosmological constant. Compared to R h = ct, versions of the standard model with more elaborate parametrizations of dark energy are judged to be even less likely

Gimenes, H. S.; Viswanathan, G. M.; Silva, R.

2018-03-01

Many models in cosmology typically assume the standard bulk viscosity. We study an alternative interpretation for the origin of the bulk viscosity. Using nonadditive statistics proposed by Tsallis, we propose a bulk viscosity component that can only exist by a nonextensive effect through the nonextensive/dissipative correspondence (NexDC). In this paper, we consider a ΛCDM model for a flat universe with a dissipative nonextensive viscous dark matter component, following the Eckart theory of bulk viscosity, without any perturbative approach. In order to analyze cosmological constraints, we use one of the most recent observations of Type Ia Supernova, baryon acoustic oscillations and cosmic microwave background data.

9-11%Cr ferritic steels play an important role in high-temperature and high-pressure boilers of advanced power plants. In this paper, a continuum damage mechanics (CDM)-based creep model was proposed to study the creep behavior of T91 and T92 steels at high temperatures. Long-time creep tests were performed for both steels under different conditions. The creep rupture data and creep curves obtained from creep tests were captured well by theoretical calculation based on the CDM model over a long creep time. It is shown that the developed model is able to predict creep data for the two ferritic steels accurately up to tens of thousands of hours.

The possibility of clean development mechanism in a nuclear power expansion in Brazil

International Nuclear Information System (INIS)

Paris, Alexandre G.; Oliveira, Wagner S.

2009-01-01

The nuclear power expansion is a very controversial topic in Brazil, which needs to be carefully addressed, especially because the national energy supply system is becoming more carbon-intensive. Although most of the electricity generated in Brazil is by hydropower plants, the country's electricity matrix expansion is moving towards a larger participation of fossil fuel thermo power generation which is contrarily the global objects of climate change mitigation. Climate change is a reality and the choice facing this problem is between action and delay. There will be needed a huge international mobilization, associated with a great amount of financial, political and engineering resources interested for preventing the aggravation of the greenhouse effect. This article analyses, in the possibility of including nuclear power in the Clean Development Mechanism (CDM) criteria, the revenue that could be generated from the trading of Certified Emission Reduction (CER) in different scenarios of nuclear power expansion in Brazil.

Tensions between several cosmic observations were found recently, such as the inconsistent values of H{sub 0} (or σ{sub 8}) were indicated by the different cosmic observations. Introducing the massive neutrinos in ΛCDM could potentially solve the tensions. Viable f(R) gravity producing ΛCDM background expansion with massive neutrinos is investigated in this paper. We fit the current observational data: Planck-2015 CMB, RSD, BAO, and SNIa to constrain the mass of neutrinos in viable f(R) theory. The constraint results at 95% confidence level are: Σm{sub ν} < 0.202 eV for the active-neutrino case, m{sub ν,sterile}{sup eff} < 0.757 eV with N{sub eff} < 3.22 for the sterile neutrino case. For the effects due to the mass of the neutrinos, the constraint results on model parameter at 95% confidence level become f{sub R0} x 10{sup -6} > -1.89 and f{sub R0} x 10{sup -6} > -2.02 for two cases, respectively. It is also shown that the fitting values of several parameters much depend on the neutrino properties, such as the cold dark matter density, the cosmological quantities at matter-radiation equality, the neutrino density and the fraction of baryonic mass in helium. Finally, the constraint result shows that the tension between direct and CMB measurements of H{sub 0} gets slightly weaker in the viable f(R) model than that in the base ΛCDM model. (orig.)

Communicable disease management (CDM) is an important component of disaster public health response operations. However, there is a lack of any performance assessment (PA) framework and related indicators for the PA. This study aimed to develop a PA framework and indicators in CDM in disasters. In this study, a series of methods were used. First, a systematic literature review (SLR) was performed in order to extract the existing PA frameworks and indicators. Then, using a qualitative approach, some interviews with purposively selected experts were conducted and used in developing the PA framework and indicators. Finally, the analytical hierarchy process (AHP) was used for weighting of the developed indicators. The input, process, products, and outcomes (IPPO) framework was found to be an appropriate framework for CDM PA. Seven main functions were revealed to CDM during disasters. Forty PA indicators were developed for the four categories. There is a lack of any existing PA framework in CDM in disasters. Thus, in this study, a PA framework (IPPO framework) was developed for the PA of CDM in disasters through a series of methods. It can be an appropriate framework and its indicators could measure the performance of CDM in disasters.

The Project Based Mechanisms of the Kyoto Protocol. Credible Instruments or Challenges to the Integrity of the Kyoto Protocol?

Energy Technology Data Exchange (ETDEWEB)

Takeuchi Waldegren, Linn

2006-03-15

The project based mechanisms of the Kyoto Protocol are innovative instruments which allow projects to earn credits for reducing greenhouse gas (GHG) emissions. The credits can in turn be used by countries to reach their emissions targets according to the Kyoto Protocol. The Project based mechanisms are known as the Clean Development Mechanism (CDM) and the Joint Implementation (JI). If the project based mechanisms are to be effective policy instruments they must ensure the integrity of the Kyoto Protocol, and their ability to promote and prove real emission reductions is critical. The environmental credibility of the project based mechanisms will also ensure their ability to promote cost effectiveness. Key concepts in this context are environmental and project additionality, and their role and value for the project based mechanisms are analyzed. Environmental additionality is established by comparing a project's emissions to a baseline. The baseline's credibility is thus vital. The concept of project additionality is somewhat controversial, but is nonetheless of equal importance. The case studies of CDM approved methodologies (AMs) and proposed projects suggest that there are credibility issues that need to be addressed if the project based mechanisms are to promote real emissions reductions.

THE VELOCITY FUNCTION IN THE LOCAL ENVIRONMENT FROM ΛCDM AND ΛWDM CONSTRAINED SIMULATIONS

Using constrained simulations of the local universe for generic cold dark matter (CDM) and for 1 keV warm dark matter (WDM), we investigate the difference in the abundance of dark matter halos in the local environment. We find that the mass function (MF) within 20 h -1 Mpc of the Local Group is ∼2 times larger than the universal MF in the 10 9 -10 13 h -1 M sun mass range. Imposing the field of view of the ongoing H I blind survey Arecibo Legacy Fast ALFA (ALFALFA) in our simulations, we predict that the velocity function (VF) in the Virgo-direction region (VdR) exceeds the universal VF by a factor of 3. Furthermore, employing a scheme to translate the halo VF into a galaxy VF, we compare the simulation results with a sample of galaxies from the early catalog release of ALFALFA. We find that our simulations are able to reproduce the VF in the 80-300 km s -1 velocity range, having a value ∼10 times larger than the universal VF in the VdR. In the low-velocity regime, 35-80 km s -1 , the WDM simulation reproduces the observed flattening of the VF. In contrast, the simulation with CDM predicts a steep rise in the VF toward lower velocities; for V max = 35 km s -1 , it forecasts ∼10 times more sources than the ones observed. If confirmed by the complete ALFALFA survey, our results indicate a potential problem for the CDM paradigm or for the conventional assumptions about energetic feedback in dwarf galaxies.

Magnetized $\\Lambda$CDM inhomogeneities and the cosmic dark ages

CERN Document Server

Giovannini, Massimo

2011-01-01

Exact solutions of the perturbations equations in the magnetized LambdaCDM scenario are presented. They apply during the dark ages and, more specifically, after the baryons are freed from the drag of the photons. The magnetized growth rate of matter perturbations is compared with the growth index obtained in the concordance paradigm and under the assumption that dark energy does not cluster for a redshift window ranging from the epoch of reionization to the stage of dark-energy dominance. The constraints derived from this analysis are shown to be qualitatively complementary and quantitatively competitive with the bounds stemming from the analysis of the distortion patterns induced by the magnetized adiabatic mode on the temperature and polarization anisotropies of the Cosmic Microwave Background.

Did CDM particles of mass 2.47 x 10(-3) eV interact with precursor biopolymers and nucleic acids to initiate and boost lifeforms on Earth?

Science.gov (United States)

Rosen, Gerald

2011-06-01

Recent observations and theoretical studies have shown that non-baryonic Cold Dark Matter (CDM), which constitutes about 84% of all matter in the Universe, may feature a complex-scalar-field that carries particles of mass ≅ 2.47 x 10(-3)eV with the associated Compton range m(-1) ≅8.02 x 10(-3) cm, a distance on the scale of extended bionucleic acids and living cells. Such a complex-scalar-field can enter a weak-isospin Lorentz-invariant interaction that generates the flow of right-handed electrons and induces a chirality-imbued quantum chemistry on the m (-1) scale. A phenomenological Volterra-type equation is proposed for the CDM-impacted time development of N, the number of base pairs in the most advanced organism at Earth-age t. The solution to this equation suggests that the boosts in N at t ≅ 1.1 Gyr (advent of the first living prokaryotic cells), at t ≅ 2.9 Gyr (advent of eukaryotic single-celled organisms) and finally at t ≅ 4.0 Gyr (the Cambrian explosion) may be associated with three multi-Myr-duration cosmic showers of the complex-scalar-field CDM particles. If so, the signature of the particles may be detectible in Cambrian rocks.

The ΛCDM cosmological model successfully reproduces many aspects of the galaxy and structure formation of the universe. However, the growth of large-scale structures (LSSs) in the early universe is not well tested yet with observational data. Here, we have utilized wide and deep optical–near-infrared data in order to search for distant galaxy clusters and superclusters (0.8 < z < 1.2). From the spectroscopic observation with the Inamori Magellan Areal Camera and Spectrograph (IMACS) on the Magellan telescope, three massive clusters at z ∼ 0.91 are confirmed in the SSA22 field. Interestingly, all of them have similar redshifts within Δ z ∼ 0.01 with velocity dispersions ranging from 470 to 1300 km s{sup −1}. Moreover, as the maximum separation is ∼15 Mpc, they compose a supercluster at z ∼ 0.91, meaning that this is one of the most massive superclusters at this redshift to date. The galaxy density map implies that the confirmed clusters are embedded in a larger structure stretching over ∼100 Mpc. ΛCDM models predict about one supercluster like this in our surveyed volume, consistent with our finding so far. However, there are more supercluster candidates in this field, suggesting that additional studies are required to determine if the ΛCDM cosmological model can successfully reproduce the LSSs at high redshift.

Promoting bioethanol production through clean development mechanism: Findings and lessons learnt from ASIATIC project

Energy Technology Data Exchange (ETDEWEB)

Gnansounou, Edgard; Bedniaguine, Denis; Dauriat, Arnaud

2005-12-15

Global climate change mitigation policies call for increasing use of biomass fuels as renewable substitutes to fossil energy resources. Quantified targets for biofuels introduction in to the market exist in the United States, the European Union, and a number of developing countries. In this context, mixing biologically produced ethanol with conventional gasoline represents an attractive technical option allowing for reducing emissions of greenhouse gases and lessening the dependence on non-renewable petrol in the transportation sector. This paper investigates technological and socio-economic aspects of ethanol production in developing countries, particularly in China, with special focus on determining eligibility of bioethanol projects for Clean Development Mechanism. Basing on the findings of the ASIATIC study (Agriculture and Small to Medium Scale Industries in Peri-urban Areas through Ethanol Production for Transport In China), we analyse how alcohol fuels can be produced in a sustainable way with mutual benefits between rural and urban people. The bioethanol production cost and life cycle CO2 eq. emissions were calculated for six different types of feedstock: sugarcane, sugarcane molasses, sweet sorghum juice, cassava, corn, and sorghum bagasse. Implications of the CDM rules and procedures for bioethanol industry were examined under the angles of environmental and economical additionality, and conformity with the principles of sustainable development. It is found that the starch-based (cassava) ethanol production path has the greatest potential for market penetration in China, followed by the conversion route using sugar-based feedstock (sorghum juice, sugarcane molasses). Meanwhile, the lignocelluloses biomass - to - ethanol technology may represent the highest interest for implementation as Clean Development Mechanism project. (Author)

CDM pilot project to stimulate market for family-hydro for low-income households

International Nuclear Information System (INIS)

2004-01-01

Over 100,000 low-income households living in rural, rice-farming regions of Vietnam and China rely upon family-hydro (between 100 and 200W) as the only affordable means of obtaining electricity. These systems are used for domestic lighting, radio and, in some cases, televisions. The units are small, cheap and are usually installed and owned by a single family. Funding from the CDM could be utilised in order to reduce the cost of good quality equipment to provide low-income households living in isolated off-grid locations with an affordable and sustainable electricity supply which can meet their needs for lighting, educational, productive and recreational uses. Therefore research was needed to determine the level of carbon emission reductions resulting from their use. The successful acceptance by the Prototype Carbon Fund (PCF) of the methodology of establishing the benchmark developed during this project could then be used as a precedent by other project developers in the future, thus being of long-term support to the emerging family-hydro industry.

Scoping study on SADC energy sector carbon market potential; SADC = Southern African Development Community

Energy Technology Data Exchange (ETDEWEB)

2010-10-22

This study shows that, while there is a certain degree of institutional and project development capacity in the region and significant Clean Development Mechanism (CDM) potential, very little of this potential is currently being tapped. National institutional structures are mostly very new, understaffed, and working in isolation from each other. There are ongoing national CDM capacity building programmes in several SADC countries that will address barriers and develop projects at a national level, but there are also regional opportunities that these programmes will not address. For some of large scale project opportunities such as landfill gas, industrial energy use, fugitive emission and transport, a national approach is required because these projects depend on local industrial base, regulatory environment, and are also large enough that the carbon revenue can cover the transaction costs. There are a few key areas that should be addressed, however, at a regional level: Energy trade and power development: any low carbon power projects that are developed to serve regional energy needs and displace coal fired power can only receive carbon credits if the baseline is a regional power grid rather than just a national grid. This is also true for large scale energy efficiency projects in countries that have only hydropower - these would not receive any carbon credits unless there is justification for a regional grid definition that includes fossil fuel fired power stations.Small scale projects: While the total potential for small scale renewables may not be large in terms of tonnes of CO{sub 2} mitigated, the local development impacts of distributed renewable energy and energy efficiency projects are very large. For these projects to be implemented at a large enough scale to recoup the transaction costs of project development, a regional approach is critical. The CDM 'Programme of Activities' (PoA) approach is ideally suited for such regional small scale energy

In this paper, the contribution to the financial and economic feasibility of cogeneration systems with gas turbine and exhaust gas heat recovery boiler is discussed in function of the financial credit for reduction of greenhouse gases emissions (GH Gs) by using the Clean Development Mechanism (CDM). It has to be kept in mind the restrictions of these systems to be capital intensive projects subject to the effects of the economy of scale. Other factors to take into account are the constancy of the heat demand, the rates of sale of electricity and steam surpluses, the regulatory laws, the ignorance of the cogeneration technologies on the part of the investor, among others. The profitability of the investment for implementation of a cogeneration system can be elevated in large facilities with gas turbines and heat recovery boiler (T G + HRSG). Results discussed in previous papers are pointed out and new conclusions are enunciated. (author)

How to use the clean development mechanism in the residential sector? The case of Brazilian refrigerators

International Nuclear Information System (INIS)

Khalil, Helioui; Cohen, Claude; Salem Szklo, Alexandre

2006-01-01

The definition of simple and reliable emission baselines is crucial to foster clean development mechanism (CDM) projects. This paper assesses a project methodology that could boost large-scale energy-efficiency projects in the sector of domestic appliances. The baseline appliance is defined a priori in a 'conservative' manner as the design option minimizing life-cycle social costs. The project methodology consists in a program which rebates new appliances according to their emission savings compared to the baseline. Is the proposed baseline acceptable? What could be the impact of such project on emissions? To address these questions, we look for insights from a hypothetical case on Brazilian refrigerators. A rational choice model is developed which assumes that households select design options minimizing life-cycle private costs. Results suggest that electricity tariff distortions and financial constraints might hamper project performances and allow significant free-riding. Low income households remain trapped into low-efficiency choices and high income households adopt outperforming appliances, whether rebated or not. However, simple solutions likely to improve the project methodology do exist

The increase in number of vehicles in metropolitan cities has resulted in increase of greenhouse gas (GHG) emissions in urban environment. In this study, emission load of GHGs (CO, N 2 O, CO 2 ) from Chandigarh road transport sector has been estimated using Vehicular Air Pollution Inventory (VAPI) model, which uses emission factors prevalent in Indian cities. Contribution of 2-wheelers (2-w), 3-wheelers (3-w), cars, buses, and heavy commercial vehicles (HCVs) to CO, N 2 O, CO 2 , and total GHG emissions was calculated. Potential for GHG mitigation through clean development mechanism (CDM) in transport sector of Chandigarh under two scenarios, i.e., business as usual (BAU) and best estimate scenario (BES) using VAPI model, has been explored. A major contribution of GHG load (~ 50%) in Chandigarh was from four-wheelers until 2011; however, it shows a declining trend after 2011 until 2020. The estimated GHG emission from motor vehicles in Chandigarh has increased more than two times from 1065 Gg in 2005 to 2486 Gg by 2011 and is expected to increase to 4014 Gg by 2020 under BAU scenario. Under BES scenario, 30% of private transport has been transformed to public transport; GHG load was possibly reduced by 520 Gg. An increase of 173 Gg in GHGs load is projected from additional scenario (ADS) in Chandigarh city if all the diesel buses are transformed to CNG buses by 2020. Current study also offers potential for other cities to plan better GHG reduction strategies in transport sector to reduce their climate change impacts.

We propose general f(R,T,R μν T μν ) theory as generalization of covariant Hořava-like gravity with dynamical Lorentz symmetry breaking. FRLW cosmological dynamics for several versions of such theory is considered. The reconstruction of the above action is explicitly done, including the numerical reconstruction for the occurrence of ΛCDM universe. De Sitter universe solutions in the presence of non-constant fluid are also presented. The problem of matter instability in f(R,T,R μν T μν ) gravity is discussed

India - Nuclear power for GHG mitigation and sustainable energy development

Nema, A.K.; Pathak, B.K.; Grover, R.B.

2000-01-01

The increasing use of the earth's resources to improve our quality of life has led to certain deleterious effects on the environment. The increased concentration of greenhouse gases (GHGs) is one such important effect. GHG emissions have come primarily from industrialized countries. Currently industrialized countries emit 11.4 tonnes of carbon per year per capita. For India the corresponding figure is 1.0, and for China it is 2.7. We recognize the necessity of both meeting the development needs of all the countries in the South, and ensuring that such development is sustainable. The CDM may have an important role to play, although the positions of a number of countries, including India, with respect to the CDM appear to be still evolving. In any event, nuclear energy should be an important energy option under the CDM, if and when the CDM is ready to be implemented. The present study is an attempt to understand the implications of setting up a nuclear power plant (NPP) in India as a CDM project

Linking project-based mechanisms with domestic greenhouse gas emissions trading schemes

Bygrave, S.; Bosi, M.

2004-01-01

Although there are a number of possible links between emission trading and project-based mechanisms, the focus of this paper is on linking domestic GHG emission trading schemes with: (1) domestic; and, (2) international (JI and CDM) GHG reduction project activities. The objective is to examine some of the challenges in linking DETs and project-based mechanisms, as well as some possible solutions to address these challenges. The link between JI / CDM and intergovernmental international emissions trading (i.e. Article 17 of the Kyoto Protocol) is defined by the Kyoto Protocol, and therefore is not covered in this paper. The paper is written in the context of: (a) countries adhering to the Kyoto Protocol and elaborating their strategies to meet their GHG emission commitments, including through the use of the emissions trading and project-based mechanisms. For example, the European Union (EU) will be commencing a GHG Emissions Trading Scheme in January 2005, and recently, the Council of ministers and the European Parliament agreed on a text for an EU Linking Directive allowing the use of JI and CDM emission units in the EU Emission Trading Scheme (EU-ETS); and (b) all countries (and/or regions within countries) with GHG emission obligations that may choose to use domestic emissions trading and project-based mechanisms to meet their GHG commitments. The paper includes the following elements: (1) an overview of the different flexibility mechanisms (i.e. GHG emissions trading and PBMs), including a brief description and comparisons between the mechanisms (Section 3); (2) an exploration of the issues that emerge when project-based mechanisms link with domestic emissions trading schemes, as well as possible solutions to address some of the challenges raised (Section 4); (3) a case study examining the EU-ETS and the EU Linking Directive on project-based mechanisms, in particular on how the EU is addressing in a practical context relevant linking issues (Section 5); (4) a

Residential, long-term care serves vulnerable older adults in a facility-based environment. A new care delivery model (CDM) designed to promote more equitable care for residents was implemented in a health region in Western Canada. Leaders and managers faced challenges in implementing this model alongside other concurrent changes. This paper explores the question: How did leadership style influence team functioning with the implementation of the CDM? Qualitative data from interviews with leadership personnel (directors and managers, residential care coordinators and clinical nurse educators), and direct care staff (registered nurses, licensed practical nurses, health care aides, and allied health therapists), working in two different facilities comprise the main sources of data for this study. The findings reveal that leaders with a servant leadership style were better able to create and sustain the conditions to support successful model implementation and higher team functioning, compared to a facility in which the leadership style was less inclusive and proactive, and more resistant to the change. Consequently, staff at the second facility experienced a greater sense of overload with the implementation of the CDM. This study concludes that strong leadership is key to facilitating team work and job satisfaction in a context of change.

The CDM Superfamily Protein MBC Directs Myoblast Fusion through a Mechanism That Requires Phosphatidylinositol 3,4,5-Triphosphate Binding but Is Independent of Direct Interaction with DCrk▿§

myoblast city (mbc), a member of the CDM superfamily, is essential in the Drosophila melanogaster embryo for fusion of myoblasts into multinucleate fibers. Using germ line clones in which both maternal and zygotic contributions were eliminated and rescue of the zygotic loss-of-function phenotype, we established that mbc is required in the fusion-competent subset of myoblasts. Along with its close orthologs Dock180 and CED-5, MBC has an SH3 domain at its N terminus, conserved internal domains termed DHR1 and DHR2 (or “Docker”), and C-terminal proline-rich domains that associate with the adapter protein DCrk. The importance of these domains has been evaluated by the ability of MBC mutations and deletions to rescue the mbc loss-of-function muscle phenotype. We demonstrate that the SH3 and Docker domains are essential. Moreover, ethyl methanesulfonate-induced mutations that change amino acids within the MBC Docker domain to residues that are conserved in other CDM family members nevertheless eliminate MBC function in the embryo, which suggests that these sites may mediate interactions specific to Drosophila MBC. A functional requirement for the conserved DHR1 domain, which binds to phosphatidylinositol 3,4,5-triphosphate, implicates phosphoinositide signaling in myoblast fusion. Finally, the proline-rich C-terminal sites mediate strong interactions with DCrk, as expected. These sites are not required for MBC to rescue the muscle loss-of-function phenotype, however, which suggests that MBC's role in myoblast fusion can be carried out independently of direct DCrk binding.

The present study evaluates a carbon sequestration project for the three plant species in arid and semiarid regions of Iran. Results show that Haloxylon performed appropriately in the carbon sequestration process during the 6 years of the International Carbon Sequestration Project (ICSP). In addition to a high degree of carbon dioxide sequestration, Haloxylon shows high compatibility with severe environmental conditions and low maintenance costs. Financial and economic analysis demonstrated that the ICSP was justified from an economic perspective. The financial assessment showed that net present value (NPV) (US$1,098,022.70), internal rate of return (IRR) (21.53%), and payback period (6 years) were in an acceptable range. The results of the economic analysis suggested an NPV of US$4,407,805.15 and an IRR of 50.63%. Therefore, results of this study suggest that there are sufficient incentives for investors to participate in such kind of Clean Development Mechanism (CDM) projects.

Ragusa, P.

2000-01-01

The Canadian International Development Agency (CIDA) is primarily responsible for Canada's official development assistance program whose objective is to foster sustainable development in order to reduce poverty and contribute to a more secure, equitable and prosperous world. CIDA programs are directed to the needs of developing countries to assist them in capacity building, to provide financial resources and technology transfer, to help them to meet the cost of adaptation to adverse effects, and to develop and enhance indigenous capabilities. With respect to climate change, CIDA, in concert with other federal government departments, endeavours to maximize Canada's capabilities to meet international environmental commitments and Kyoto climate change targets at the lowest cost, ensure a level playing field with Canada's competitors by maximizing participation of major developed and developing economies in the Kyoto Protocol, and maximize opportunities for Canadian businesses in international projects and initiatives in climate change. Accordingly, the 2000 CIDA Budget provides official development assistance funding of $100 million over four years for technology transfer to help developing countries reduce their greenhouse gas emissions and promote sustainable development. First call for proposals is targeted for August 2001, with assessment of proposals and projects during September and second call for proposals before year end. Major provisions of the Kyoto Protocol, the purposes of the Clean Development Mechanism, the role that CIDA can play in support of implementation of CDM, benefits and opportunities provided by CDM are summarized. Ways in which private sector firms seeking to expand into developing countries can benefit by working with CIDA, are also discussed

This paper examines the organizational arrangements for technology supply in solar photovoltaic projects in the Clean Development Mechanism (CDM). It shows that while lower middle-income countries typically import solar PV equipment into CDM projects, China, India and Thailand have begun to use new...... organizational arrangements for technology transfer which reflect the overall industry maturity in the solar PV sectors in these countries. This has great potential for long-term climate change mitigation efforts. However, the initiation of these new organizational arrangements often preceded the supply...... of technology into CDM projects. This raises important questions about the role of CDM in spearheading the development of technological capabilities required for sustainable development. The paper uses these findings to add to the literature about technology in CDM and to the wider policy debates over...

We discuss the existence of a dividing shell separating expanding and collapsing regions in spherically symmetric solutions with pressure. We obtain gauge invariant conditions relating not only the intrinsic spatial curvature of the shells to the ADM mass, but also a function of the pressure which we introduce that generalises the Tolman-Oppenheimer-Volkoff equilibrium condition, in the framework of a 3+1 spacetime splitting. We consider the particular case of a Lema\\^itre-Tolman-Bondi dust models with a cosmological constant (a $\\Lambda$-CDM model) as an example of our results.

Motivated by the fact that any nonzero Λ can introduce a length scale or a time scale into Einstein's theory, r Λ =ct Λ =√(3/|Λ|). Conversely, any cosmological length scale or time scale can introduce a Λ(t), Λ(t)=3/r Λ 2 (t)=3/(c 2 t Λ 2 (t)). In this Letter, we investigate the time varying Λ(t) corresponding to the length scales, including the Hubble horizon, the particle horizon and the future event horizon, and the time scales, including the age of the universe and the conformal time. It is found out that, in this scenario, the Λ(t)CDM model can be taken as the unified origin of the holographic and agegraphic dark energy models with interaction between the matter and the dark energy, where the interacting term is determined by Q=-ρ . Λ . We place observational constraints on the Λ(t)CDM models originating from different cosmological length scales and time scales with the recently compiled 'Union2 compilation' which consists of 557 Type Ia supernovae (SNIa) covering a redshift range 0.015≤z≤1.4. In conclusion, an accelerating expansion universe can be derived in the cases taking the Hubble horizon, the future event horizon, the age of the universe and the conformal time as the length scale or the time scale.

Peculiar velocities of objects in the nearby universe are correlated due to the gravitational pull of large-scale structure. By measuring these velocities, we have a unique opportunity to test the cosmological model at the lowest redshifts. We perform this test, using current data to constrain the amplitude of the ''signal'' covariance matrix describing the velocities and their correlations. We consider a new, well-calibrated ''Supercal'' set of low-redshift SNe Ia as well as a set of distances derived from the fundamental plane relation of 6dFGS galaxies. Analyzing the SN and galaxy data separately, both results are consistent with the peculiar velocity signal of our fiducial ΛCDM model, ruling out the noise-only model with zero peculiar velocities at greater than 7σ (SNe) and 8σ (galaxies). When the two data sets are combined appropriately, the precision of the test increases slightly, resulting in a constraint on the signal amplitude of A = 1.05{sub −0.21}{sup +0.25}, where A = 1 corresponds to our fiducial model. Equivalently, we report an 11% measurement of the product of the growth rate and amplitude of mass fluctuations evaluated at z {sub eff} = 0.02, f σ{sub 8} = 0.428{sub −0.045}{sup +0.048}, valid for our fiducial ΛCDM model. We explore the robustness of the results to a number of conceivable variations in the analysis and find that individual variations shift the preferred signal amplitude by less than ∼0.5σ. We briefly discuss our Supercal SN Ia results in comparison with our previous results using the JLA compilation.

Linear perturbation theory for tidal streams and the small-scale CDM power spectrum

Bovy, Jo; Erkal, Denis; Sanders, Jason L.

2017-04-01

Tidal streams in the Milky Way are sensitive probes of the population of low-mass dark matter subhaloes predicted in cold dark matter (CDM) simulations. We present a new calculus for computing the effect of subhalo fly-bys on cold streams based on the action-angle representation of streams. The heart of this calculus is a line-of-parallel-angle approach that calculates the perturbed distribution function of a stream segment by undoing the effect of all relevant impacts. This approach allows one to compute the perturbed stream density and track in any coordinate system in minutes for realizations of the subhalo distribution down to 105 M⊙, accounting for the stream's internal dispersion and overlapping impacts. We study the statistical properties of density and track fluctuations with large suites of simulations of the effect of subhalo fly-bys. The one-dimensional density and track power spectra along the stream trace the subhalo mass function, with higher mass subhaloes producing power only on large scales, while lower mass subhaloes cause structure on smaller scales. We also find significant density and track bispectra that are observationally accessible. We further demonstrate that different projections of the track all reflect the same pattern of perturbations, facilitating their observational measurement. We apply this formalism to data for the Pal 5 stream and make a first rigorous determination of 10^{+11}_{-6} dark matter subhaloes with masses between 106.5 and 109 M⊙ within 20 kpc from the Galactic centre [corresponding to 1.4^{+1.6}_{-0.9} times the number predicted by CDM-only simulations or to fsub(r matter is clumpy on the smallest scales relevant for galaxy formation.

The EU has proposed four flexibility mechanisms for the regulation of greenhouse gas emissions in the period 2013-2020: (1) the Emissions Trade Scheme (ETS), a permit market between selected companies; (2) trade in non-ETS allotments between Member States; (3) the Clean Development Mechanism (CDM) to purchase offsets in developing countries; and (4) trade in CDM warrants between Member States. This paper shows that aggregate abatement costs fall as flexibility increases. However, limited flex...

Market Mechanisms and the Use of Renewables in the Power Sectors of Asia and Europe

International Nuclear Information System (INIS)

Delgado, Guido Alfredo A.

2005-01-01

There are tremendous renewable energy (RE) resources around the world which when tapped for power generation could contribute a significant component to the application of a Clean Development Mechanism (CDM). In Europe, and in other more developed economies, governments have made strategic commitments in fostering the use of cleaner burning fuels and sealed in place financial tools and policies that put RE technology on par, or at the very least, in competing mode with traditional energy resources. On the other hand, Asia and other developing nations, paint a different picture. There are no concrete policy statements and programmes supporting RE technology, or if there are, the vision has been greatly impaired owing to various factors such as but not limited to: poverty and the lack of capital fund, a helpless reliance on grant-based development assistance programmes, lack of financial incentives, product unawareness and immaturity of the market. Owing largely, perhaps, to the convenience and cheaper initial cost of using traditional energy resources, RE technology does not stand a chance, if at all, in competition with traditional energy sources as demands for it have not been properly advanced. The development of RE technology which would have spelled the broader use of international CDM mechanisms has, therefore, really been difficult in the region. Only a number of Asian countries have policies that support the development of renewable energy. On the contrary, some of them give more priority to the development of conventional energy sources, thus there is limited funding and incentives for renewable energy development. If these data are looked into, and with the help of investors, lenders, and developers, governments in these countries may yet be able to focus on developing RE technology that can contribute power generation for its electrification programmes

Disruptive Technologies in Workmanship: pH-neutral Flux, CDM ESD Events, HDI PCBs

Science.gov (United States)

Plante, Jeannette F.

2010-01-01

This slide presentation describes what it calls "disruptive technologies", i.e., "Low-end disruption" occurs when the rate at which products improve exceeds the rate at which customers can adopt the new performance. Therefore, at some point the performance of the product overshoots the needs of certain customer segments. At this point, a disruptive technology may enter the market and provide a product which has lower performance than the incumbent but which exceeds the requirements of certain segments, thereby gaining a foothold in the market. This concept is viewed in impacting incumbent technologies Rosin Flux, with a pH-neutral water soluble Flux; electrostatic discharge models being disrupted by the charge device model (CDM) concept; and High Density Interconnect Printed Circuit Boards (HDI PCB).

The dynamics of the ΛCDM model can be reproduced only if two conditions are satisfied: 1) the entropy density production rate and the particle density variation rate are equal and 2) the (negative) pressure associated to the creation process is constant. However, the matter creation model predicts a present dark matter-to-baryon ratio much larger than that observed in massive X-ray clusters of galaxies, representing a potential difficulty for the model. In the linear regime, a fully relativistic treatment indicates that baryons are not affected by the creation process but this is not the case for dark matter. Both components evolve together at early phases but lately the dark matter density contrast decreases since the background tends to a constant value. This behaviour produces a negative growth factor, in disagreement with observations, being a further problem for this cosmology

3D Progressive Damage Modeling for Laminated Composite Based on Crack Band Theory and Continuum Damage Mechanics

2015-01-01

A simple continuum damage mechanics (CDM) based 3D progressive damage analysis (PDA) tool for laminated composites was developed and implemented as a user defined material subroutine to link with a commercially available explicit finite element code. This PDA tool uses linear lamina properties from standard tests, predicts damage initiation with an easy-to-implement Hashin-Rotem failure criteria, and in the damage evolution phase, evaluates the degradation of material properties based on the crack band theory and traction-separation cohesive laws. It follows Matzenmiller et al.'s formulation to incorporate the degrading material properties into the damaged stiffness matrix. Since nonlinear shear and matrix stress-strain relations are not implemented, correction factors are used for slowing the reduction of the damaged shear stiffness terms to reflect the effect of these nonlinearities on the laminate strength predictions. This CDM based PDA tool is implemented as a user defined material (VUMAT) to link with the Abaqus/Explicit code. Strength predictions obtained, using this VUMAT, are correlated with test data for a set of notched specimens under tension and compression loads.

The spherical Jeans equation is a widely used tool for dynamical study of gravitating systems in astronomy. Here, we test its efficacy in robustly weighing the mass of Milky Way analogues, given they need not be in equilibrium or even spherical. Utilizing Milky Way stellar haloes simulated in accordance with Λ cold dark matter (ΛCDM) cosmology by Bullock and Johnston and analysing them under the Jeans formalism, we recover the underlying mass distribution of the parent galaxy, within distance r/kpc ∈ [10, 100], with a bias of ˜ 12 per cent and a dispersion of ˜ 14 per cent. Additionally, the mass profiles of triaxial dark matter haloes taken from the SURFS simulation, within scaled radius 0.2 < r/rmax < 3, are measured with a bias of ˜ - 2.4 per cent and a dispersion of ˜ 10 per cent. The obtained dispersion is not because of Poisson noise due to small particle numbers as it is twice the later. We interpret the dispersion to be due to the inherent nature of the ΛCDM haloes, for example being aspherical and out-of-equilibrium. Hence, the dispersion obtained for stellar haloes sets a limit of about 12 per cent (after adjusting for random uncertainty) on the accuracy with which the mass profiles of the Milky Way-like galaxies can be reconstructed using the spherical Jeans equation. This limit is independent of the quantity and quality of the observational data. The reason for a non-zero bias is not clear, hence its interpretation is not obvious at this stage.

Non-Gaussian initial conditions in ΛCDM: Newtonian, relativistic, and primordial contributions

2014-01-01

The goal of the present paper is to set initial conditions for structure formation at nonlinear order, consistent with general relativity, while also allowing for primordial non-Gaussianity. We use the nonlinear continuity and Raychaudhuri equations, which together with the nonlinear energy constraint, determine the evolution of the matter density fluctuation in general relativity. We solve this equations at first and second order in a perturbative expansion, recovering and extending previous results derived in the matter-dominated limit and in the Newtonian regime. We present a second-order solution for the comoving density contrast in a ΛCDM universe, identifying nonlinear contributions coming from the Newtonian growing mode, primordial non-Gaussianity and intrinsic non-Gaussianity, due to the essential nonlinearity of the relativistic constraint equations. We discuss the application of these results to initial conditions in N-body simulations, showing that relativistic corrections mimic a non-zero nonlinear parameter f NL

We propose general f(R,T,R{sub μν}T{sup μν}) theory as generalization of covariant Hořava-like gravity with dynamical Lorentz symmetry breaking. FRLW cosmological dynamics for several versions of such theory is considered. The reconstruction of the above action is explicitly done, including the numerical reconstruction for the occurrence of ΛCDM universe. De Sitter universe solutions in the presence of non-constant fluid are also presented. The problem of matter instability in f(R,T,R{sub μν}T{sup μν}) gravity is discussed.

Aiming at exploring the nature of dark energy (DE), we use forty-three observational Hubble parameter data (OHD) in the redshift range 0 measurements. The binning methods turn out to be promising and considered to be robust. By applying the two-point diagnostic to the binned data, we find that although the best-fit values of Omh^2 fluctuate as the continuous redshift intervals change, on average, they are continuous with being constant within 1 σ confidence interval. Therefore, we conclude that the ΛCDM model cannot be ruled out.

EU energy/environmental policy has at least two major and interrelated goals: to increase the percentage of electricity from renewable energy sources (RES-E) and to control the emission of GHG cost efficiently. These two goals could be in conflict. This paper explores one aspect of this conflicting relationship, namely the effect that the use of the Kyoto Protocol project mechanisms (CDM/JI project) may have on the deployment of RES-E within EU borders. The main conclusion is that, under certain assumptions (i.e., no mandatory EU RES-E quota), CDM/JI projects might reduce the incentive to deploy RES-E within EU borders because they would allow European power companies to comply with GHG targets in a cheaper way than if they reduced emissions by investing in renewable electricity in Europe. This is problematic, since many benefits from renewable electricity are local and these would be gone. This situation would be different if a mandatory RES-E quota (combined with an EU-wide TGC scheme) was implemented. In this case, the RES-E target would be fulfilled and CDM/JI projects would only affect RES-E deployment exceeding the target. (author)

Among the publications of CDC Climat Research, 'Climate Briefs' presents, in a few pages, hot topics in climate change policy. This issue addresses the following points: In order to achieve its long-term emission reduction target following the Fukushima incident, Japan would rely more heavily on international offsetting activities. Concurrent to vigorous proposals to reform the CDM, Japan is also promoting an offset crediting scheme through bilateral agreements with developing countries as a post-2012 market mechanism. Despite potential benefits, issues relating to the accounting rules, environmental integrity and implications to carbon markets warrant further consideration prior to international recognition

The current actions of economic and industrial activities have resulted in increase of the concentration of greenhouse gases in the atmosphere since 1750. According to IPCC (2007) this alteration can increase the average temperature in the planet between 1,8 and 4,0 deg C up to 2100. The climate changes and the global warming are the most complicated environmental questions of our time and the actions took now will have effect on the future generations. In this context, a series of world-wide conferences and diverse scientific quarrels had occurred throughout the last decade, which culminated in the most important multilateral agreement firmed on climate changes, the Kyoto Protocol, signed in 1997. The Protocol is a landmark in the attempts of mitigation of the climate changes, since it established the commitment of the industrialized countries with emissions reduction targets of 5,2% to the level of 1990 emissions. To achieve such targets these countries count on three flexibilization mechanisms provided by the Kyoto Protocol: Joint implementation, Emission Trading and the Clean Development Mechanism (CDM) that it will be object of this study. The objective of this thesis is to carry through an evaluation of the CDM since its conception until the current days, searching to identify its dynamics and the main inherent gaps of this instrument and finally present two case studies of the bio diesel and wind energy uses in Brazil.

Testing ΛCDM cosmology at turnaround: where to look for violations of the bound?

International Nuclear Information System (INIS)

Tanoglidis, D.; Pavlidou, V.; Tomaras, T.N.

In ΛCDM cosmology, structure formation is halted shortly after dark energy dominates the mass/energy budget of the Universe. A manifestation of this effect is that in such a cosmology the turnaround radius—the non-expanding mass shell furthest away from the center of a structure— has an upper bound. Recently, a new, local, test for the existence of dark energy in the form of a cosmological constant was proposed based on this turnaround bound. Before designing an experiment that, through high-precision determination of masses and —independently— turnaround radii, will challenge ΛCDM cosmology, we have to answer two important questions: first, when turnaround-scale structures are predicted to be close enough to their maximum size, so that a possible violation of the bound may be observable. Second, which is the best mass scale to target for possible violations of the bound. These are the questions we address in the present work. Using the Press-Schechter formalism, we find that turnaround structures have in practice already stopped forming, and consequently, the turnaround radius of structures must be very close to the maximum value today. We also find that the mass scale of ∼ 10 13  M ⊙ characterizes the turnaround structures that start to form in a statistically important number density today —and even at an infinite time in the future, since structure formation has almost stopped. This mass scale also separates turnaround structures with qualitatively different cosmological evolution: smaller structures are no longer readjusting their mass distribution inside the turnaround scale, they asymptotically approach their ultimate abundance from higher values, and they are common enough to have, at some epoch, experienced major mergers with structures of comparable mass; larger structures exhibit the opposite behavior. We call this mass scale the transitional mass scale and we argue that it is the optimal for the purpose outlined above. As a corollary

We investigate whether a self-interacting Brans-Dicke theory in d=5 without matter and with a time-dependent metric can describe, after dimensional reduction to d=4, the FLRW model with accelerated expansion and non-relativistic matter. By rewriting the effective 4-dimensional theory as an autonomous 3-dimensional dynamical system and studying its critical points, we show that the ΛCDM cosmology cannot emerge from such a model. This result suggests that a richer structure in d=5 may be needed to obtain the accelerated expansion as well as the matter content of the 4-dimensional universe.

Verification of CDM performance, reliability, and magnet production processes will be accomplished during the development phase of the program. Key features of this program include thorough in process testing of magnet subassemblies, verification of the magnetic field quality, and demonstration of the CDM performance during the formal qualification program. Reliability demonstration of the CDM design includes component tests and an accelerated life test program. Prototype magnet phase will address achievement of magnet performance goals through a program of fabrications, test, analysis, redesign as required and procurement of modified parts for a second fabrication run. This process would be repeated again if necessary, and would conclude with a final design for the production magnets. Production process validation will address the effects that key production processes have upon magnet performance, using the magnets produced during the Preproduction phase

Using velocity dispersion to estimate halo mass: Is the Local Group in tension with ΛCDM?

Science.gov (United States)

Elahi, Pascal J.; Power, Chris; Lagos, Claudia del P.; Poulton, Rhys; Robotham, Aaron S. G.

2018-06-01

Satellite galaxies are commonly used as tracers to measure the line-of-sight (LOS)velocity dispersion (σLOS) of the dark matter halo associated with their central galaxy, and thereby to estimate the halo's mass. Recent observational dispersion estimates of the Local Group, including the Milky Way and M31, suggest σ ˜50 km s-1, which is surprisingly low when compared to the theoretical expectation of σ ˜100 km s-1 for systems of their mass. Does this pose a problem for Lambda cold dark matter (ΛCDM)? We explore this tension using the SURFS suite of N-body simulations, containing over 10000 (sub)haloes with well tracked orbits. We test how well a central galaxy's host halo velocity dispersion can be recovered by sampling σLOS of subhaloes and surrounding haloes. Our results demonstrate that σLOS is biased mass proxy. We define an optimal window in vLOS and projected distance (Dp) - 0.5 ≲ Dp/Rvir ≲ 1.0 and vLOS ≲ 0.5Vesc, where Rvir is the virial radius and Vesc is the escape velocity - such that the scatter in LOS to halo dispersion is minimized - σLOS = (0.5 ± 0.1)σv, H. We argue that this window should be used to measure LOS dispersions as a proxy for mass, as it minimises scatter in the σLOS-Mvir relation. This bias also naturally explains the results from McConnachie (2012), who used similar cuts when estimating σLOS, LG, producing a bias of σLG = (0.44 ± 0.14)σv, H. We conclude that the Local Group's velocity dispersion does not pose a problem for ΛCDM and has a mass of log M_{LG, vir}/M_{⊙}=12.0^{+0.8}_{-2.0}.

Designing a carbon market that protects forests in developing countries.

Niesten, Eduard; Frumhoff, Peter C; Manion, Michelle; Hardner, Jared J

2002-08-15

Firmly incorporated into the Kyoto Protocol, market mechanisms offer an innovative and cost-effective means of controlling atmospheric concentrations of greenhouse gases. However, as with markets for many other goods and services, a carbon market may generate negative environmental externalities. Possible interpretations and application of Kyoto provisions under COP-6bis and COP-7 raise concerns that rules governing forestry with respect to the Kyoto carbon market may increase pressure on native forests and their biodiversity in developing countries. In this paper, we assess the following two specific concerns with Kyoto provisions for forestry measures. First, whether, under the Clean Development Mechanism (CDM), by restricting allowable forestry measures to afforestation and reforestation, and explicitly excluding protection of threatened native forests, the Kyoto Protocol will enhance incentives for degradation and clearing of forests in developing countries; second, whether carbon crediting for forest management in Annex I (industrialized) regions under Article 3.4 creates a dynamic that can encourage displacement of timber harvests from Annex I countries to developing nations. Given current timber extraction patterns in developing regions, additional harvest pressure would certainly entail a considerable cost in terms of biodiversity loss. In both cases, we find that the concerns about deleterious impacts to forests and biodiversity are justified, although the scale of such impacts is difficult to predict. Both to ensure reliable progress in managing carbon concentrations and to avoid unintended consequences with respect to forest biodiversity, the further development of the Kyoto carbon market must explicitly correct these perverse incentives. We recommend several steps that climate policymakers can take to ensure that conservation and restoration of biodiversity-rich natural forests in developing countries are rewarded rather than penalized.

The Kyoto Protocol allows some flexibility in the implementation of methods for achieving the goal, such as emission trading, activities implemented jointly (AIJ) among advanced countries, construction of clean development mechanisms (CDM) with developing countries, etc., and Japan intends to positively make use of them for the achievement of the goal. For China, who holds second place in the list of greenhouse gas emitting countries in the world, the promotion of CDM is quite important. With the situation taken into consideration, interaction was effected with Chinese officers and scientists of government agencies and academic institutes involved in environmental matters, and researches were conducted. Views and information were exchanged regarding environmental problems and, after on-site investigations, researches were conducted and suggestions were presented as to how AIJ and CDM should be. The suggestions covered Chinese policies toward AIJ and CDM, current state of AIJ projects in China and systems for their promotion, means for enhancing such projects, and discovery of candidates for AIJ and CDM project application.

A Continuum Damage Mechanics Model to Predict Kink-Band Propagation Using Deformation Gradient Tensor Decomposition

Science.gov (United States)

Bergan, Andrew C.; Leone, Frank A., Jr.

2016-01-01

A new model is proposed that represents the kinematics of kink-band formation and propagation within the framework of a mesoscale continuum damage mechanics (CDM) model. The model uses the recently proposed deformation gradient decomposition approach to represent a kink band as a displacement jump via a cohesive interface that is embedded in an elastic bulk material. The model is capable of representing the combination of matrix failure in the frame of a misaligned fiber and instability due to shear nonlinearity. In contrast to conventional linear or bilinear strain softening laws used in most mesoscale CDM models for longitudinal compression, the constitutive response of the proposed model includes features predicted by detailed micromechanical models. These features include: 1) the rotational kinematics of the kink band, 2) an instability when the peak load is reached, and 3) a nonzero plateau stress under large strains.

The role of offsets in a post-Kyoto climate agreement: The power sector in China

International Nuclear Information System (INIS)

Partridge, Ian; Gamkhar, Shama

2010-01-01

This paper considers how an offset scheme specific to the electricity generation sector could incentivize emissions cuts while avoiding the problems encountered by the Clean Development Mechanism (CDM). It proposes an approach to project evaluation based on measures of additionality, economic viability and contribution to sustainable development specific to this sector and re-evaluates 460 registered CDM projects in China that generate electricity using wind, natural gas or small hydro. It concludes that many small hydro schemes would be viable without the CDM subsidy. Although these projects have zero emissions from operations, offsets issued to projects that are viable without subsidy permit increased emissions in developed countries and lead to a net increase in global emissions. To provide some indication of the sustainable development benefits that CDM projects bring to their host countries, the paper includes estimates of the projects' benefit to public health due to the reduced use of coal for generation. The paper provides insights into the economics of projects and their value to host countries that are missed by the official CDM methodologies. It contributes to the debate over the design of sector-specific offset schemes that may be part of a new global agreement on combating climate change.

We estimate the expected distribution of displacements between the two dominant dark matter (DM) peaks (DM-DM displacements) and between the DM and gaseous baryon peak (DM-gas displacements) in DM halos with masses larger than 10{sup 13} h {sup –1} M {sub ☉}. As a benchmark, we use the observation of SL2S J08544–0121, which is the lowest mass system (1.0 × 10{sup 14} h {sup –1} M {sub ☉}) observed so far, featuring a bi-modal DM distribution with a dislocated gas component. We find that (50 ± 10)% of the DM halos with circular velocities in the range 300-700 km s{sup –1} (groups) show DM-DM displacements equal to or larger than 186 ± 30 h {sup –1} kpc as observed in SL2S J08544–0121. For DM halos with circular velocities larger than 700 km s{sup –1} (clusters) this fraction rises to (70 ± 10)%. Using the same simulation, we estimate the DM-gas displacements and find that 0.1%-1.0% of the groups should present separations equal to or larger than 87 ± 14 h {sup –1} kpc, corresponding to our observational benchmark; for clusters, this fraction rises to (7 ± 3)%, consistent with previous studies of DM to baryon separations. Considering both constraints on the DM-DM and DM-gas displacements, we find that the number density of groups similar to SL2S J08544–0121 is ∼6.0 × 10{sup –7} Mpc{sup –3}, three times larger than the estimated value for clusters. These results open up the possibility for a new statistical test of ΛCDM by looking for DM-gas displacements in low mass clusters and groups.

Kansai Electric Power has developed a system which reads the demand data for 30min. stored in the compound demand meter for power supply/demand (CDM), and prints the load curves. It is for customers of high-voltage power of less than 500kW, where load management is less extensive than that in larger users, for initial consulting on improvement of load factor (recommendation of heat storage contracts). It is to be installed on the spot to display the load curves, to allow the expert visiting the site to issue initial proposals immediately. It displays `daily demands by time zone` instead of `monthly power consumption` previously provided, and makes the graph of demands by time zone. It is designed to be compact, light, and easily and safely handled. The field test results indicate that the system can be sufficiently practical with the major performance items. 4 figs., 1 tab.

Canine degenerative myelopathy (CDM) represents a unique naturally occurring animal model for human amyotrophic lateral sclerosis (ALS) because of similar clinical signs, neuropathologic findings, and involvement of the superoxide dismutase 1 (SOD1) mutation. A definitive diagnosis can only be made postmortem through microscopic detection of axonal degeneration, demyelination and astroglial proliferation, which is more severe in the dorsal columns of the thoracic spinal cord and in the dorsal portion of the lateral funiculus. Interestingly, the muscle acetylcholine receptor complexes are intact in CDM prior to functional impairment, thus suggesting that muscle atrophy in CDM does not result from physical denervation. Moreover, since sensory involvement seems to play an important role in CDM progression, a more careful investigation of the sensory pathology in ALS is also warranted. The importance of SOD1 expression remains unclear, while oxidative stress and denatured ubiquinated proteins appear to play a crucial role in the pathogenesis of CDM. In this updated narrative review we performed a systematic search of the published studies on CDM that may shed light on the pathophysiological mechanisms of human ALS. A better understanding of the factors that determine the disease progression in CDM may be beneficial for the development of effective treatments for ALS. Copyright © 2015 Elsevier GmbH.

Carbon trading as incentive for conversion to organic agriculture. Case study. Organic peanuts in Tanzania

Energy Technology Data Exchange (ETDEWEB)

Bodnar, F.

2005-12-15

In this pilot project, the climate effects of the conversion from conventional to organic cultivation of peanuts are evaluated. We could aim at voluntary carbon credits that do not comply with the CDM (Clean Development Mechanisms) rules, but we try to meet the CDM rules by combining it with a agroforestry component. However, in the example of Tanzania meeting the CDM rules was a problem. The agricultural system in Tanzania consists of a rotation of several years cultivation and several years fallow. This fallow of grass, shrubs and trees could be considered as 'forest'. Taking fallow land into cultivation would then be deforestation, which would make the planting of trees no longer eligible under CDM. This is a shame because the traditional 'slash and burn' system emits a lot of greenhouse gases.

CARBON ACCOUNTING INITIATIVES: CASE STUDY OF A PETROLEUM REFINERY IN MALAYSIA TO PREPARE FOR FUTURE CARBON MARKET

Directory of Open Access Journals (Sweden)

AMANDA H.L. CHEE

2010-06-01

Full Text Available Petroleum refining process produces a large amount of atmospheric pollutants including greenhouse gases which are attributed to global warming. The international community inevitably addressed the global warming issue by introducing a market-based mechanism known as Emission Trading Systems (ETS under the Kyoto Protocol which imposes binding limits to developed nations using three flexibility mechanisms, including the Clean Development Mechanism (CDM. This case study was carried out in a petroleum refinery in Malaysia to explore the possibility for the refinery to participate in CDM. Information was collected through observatory field survey at the refinery and documentation review. Results show that the current monitoring tool using indirect calculation of fuel consumption provides a comprehensive coverage of emission sources but the reporting frequency should be increased for data accuracy. An accounting system was then created to predict the emissions gap of the refinery with reference to the baseline-year set by the Kyoto Protocol. It was concluded that the refinery showed promising potential to participate in CDM to benefit from technology transfer by selling their ‘credits’ to Annex I countries despite the uncertainty on the impact of the carbon market in a Non-Annex I country.

Evaluating experience with electricity generating GHG mitigation projects

Energy Technology Data Exchange (ETDEWEB)

Ellis, J.

2003-07-01

Several programmes have been initiated to encourage the development of projects that mitigate emissions of greenhouse gases. Recent programmes have been undertaken at the national level, such as the Dutch five-track approach, including contracts with multilateral institutions, regional development banks, private banks, bilateral contracts with countries, participation in carbon funds and the ERUPT and CERUPT tenders, Japanese Clean Development Mechanism (CDM) feasibility studies, and the more recent Finnish, Austrian and Italian JI/CDM programmes. International programmes, such as the World Bank's Prototype Carbon Fund (and other WB carbon funds), have also been initiated. Individual projects not belonging to particular programmes have also been initiated under the pilot phase of 'activities implemented jointly' (AIJ) under the United Nations Framework Convention on Climate Change (UNFCCC), or developed as CDM or Joint Implementation (JI) projects. Some CDM project activities have been formally submitted to the CDM's Executive Board (EB), who approved the first set of baseline and monitoring methodologies for CDM project activities in July 2003. There is a large variety in the type of projects that have been put forward. These include energy, industry, forestry and waste projects. This paper will focus on CDM-type projects that generate grid-connected electricity for several reasons: demand for electricity is growing rapidly in many potential host countries; many projects in the electricity sector have been developed as potential CDM and JI projects; assessing additionality and baselines is arguably more difficult for projects in the electricity sector (where a range of project types may occur as part of business-as-usual activities) than for end-of-pipe projects such as landfill gas capture and flaring or decomposition of F-gases; much work has been done on assessing appropriate methods to determine baselines in the electricity sector, at the

The role of the clean development mechanism in facilitating the application of biomass renewable energy technologies in Malaysia

Kheng, Wong Hwee; Hvid, Joergen

2003-01-01

The Malaysian Government's move to ratify the Kyoto Protocol in September 2001 reaffirms the country's support to combat global climate change. Although Malaysia is not bound by any commitments to reduce its greenhouse gas emissions, the opportunities that exist through the Clean Development Mechanism (CDM) could be two-fold: to contribute to the country's sustainable development objectives and to improve the energy supply security through the application of clean energy technologies such as renewable energy technologies. Malaysia is very dependent on fossil fuel based technologies for electricity generation and energy production. In 2001 almost 90% of the total energy input to power stations was derived from fossil fuels. Although the energy mix will continue to be predominantly based on fossil fuels, indigenous renewable energy resources may come to play a noticeable role in complementing the depleting fossil fuels. This paper focuses on how best to utilize the oil palm residues for electricity generation and energy production as these residues are the 'low hanging fruits' that are readily available. It compares the use of two different technological uses of residues: distributes power generation and co-firing with coal in large-scale power plants. The paper analyses the financial, economic and environmental impacts of these technologies, and it discusses the relative benefits of the technologies. In addition, the paper look into the barriers associated with each of the technologies, and it suggests possible policy interventions to be adopted in order to promote a viable and environmentally efficient use of the limited biomass resources.

Beyond pure offsetting: Assessing options to generate Net-Mitigation-Effects in carbon market mechanisms

International Nuclear Information System (INIS)

Warnecke, Carsten; Wartmann, Sina; Höhne, Niklas; Blok, Kornelis

2014-01-01

The current project-based carbon market mechanisms such as the Clean Development Mechanism (CDM) and the Joint Implementation (JI) do not have a direct impact on global greenhouse gas emission levels, because they only replace or offset emissions. Nor do they contribute to host country's national greenhouse gas emission reduction targets. Contributions to net emission reductions in host countries is likely to become mandatory in new mechanisms under development such as in the framework for various approaches, a new market-based mechanism and even in a reformed JI. This research analysed the question if approaches for carbon market-based mechanisms exist that allow the generation of net emission reductions in host countries while keeping project initiation attractive. We present a criteria-based assessment method and apply it for four generic options in existing mechanisms and derive implications for future mechanism frameworks. We identified the application of “discounts” on the amount of avoided emissions for the issuance of carbon credits and “standardisation below business as usual” as most promising options over “limiting the crediting period” and “over-conservativeness”. We propose to apply these options differentiated over project types based on internal rate of return to ensure cost-efficiency and attractiveness. - Highlights: • Options for net emission reductions of market-based mechanisms are assessed. • Research combines past and current views for project and sector-based mechanisms. • Implementation ensures initiation of mitigation activities is not discouraged. • Important insights for methodological design of new market-based mechanisms. • Profitability-based approach for project-based mechanisms suggested

Constructing carbon offsets: The obstacles to quantifying emission reductions

International Nuclear Information System (INIS)

Millard-Ball, Adam; Ortolano, Leonard

2010-01-01

The existing literature generally ascribes the virtual absence of the transport sector from the Clean Development Mechanism (CDM) to the inherent complexity of quantifying emission reductions from mobile sources. We use archival analysis and interviews with CDM decision-makers and experts to identify two additional groups of explanations. First, we show the significance of aspects of the CDM's historical evolution, such as the order in which methodologies were considered and the assignment of expert desk reviewers. Second, we highlight inconsistencies in the treatment of uncertainty across sectors. In contrast to transport methodologies, other sectors are characterized by a narrow focus on sources of measurement uncertainty and a neglect of economic effects ('market leakages'). We do not argue that the rejection of transport methodologies was unjustified, but rather than many of the same problems are inherent in other sectors. Thus, the case of transport sheds light on fundamental problems in quantifying emission reductions under the CDM. We argue that a key theoretical attraction of the CDM-equalization of marginal abatement costs across all sectors-has been difficult to achieve in practice.

Report on basic survey project for promoting joint implementation in 1999. Feasibility studies on reduction of CO2 emission by introduction of energy saving equipment in 3 major Philippine pulp and paper mills

Energy Technology Data Exchange (ETDEWEB)

NONE

2000-03-01

Feasibility studies were carried out on major Philippine pulp and paper mills to introduce energy saving technologies possessed by Japan and reduce emission of greenhouse effect gases. The studies are intended to be linked to the clean development mechanism (CDM) in the future. The factories chosen as the object of the studies are TIPCO, UPPC and CCP. The energy saving facilities to be introduced are the energy saving type screen, speed variable motors, power regenerative braking of winder roll-out section, installation of a dryer roll spoiler bar, and waste heat recovering devices. Therefore, it is necessary that Japan accept sharing the fund in return that this project is performed as a CDM, and credit on reduction of CO2 emission is transferred. Because of indistinctness in the CDM framework at the present as to the specific ratio of fund sharing, and of the value of the reduction quantity credit, further discussions will be required after these situations have been made clear. Since the Philippine government is not favorably disposed toward the CDM, agreement on this project as a CDM appears difficult. (NEDO)

Navigating the global carbon market

Schneider, Malte; Hendrichs, Holger; Hoffmann, Volker H.

2010-01-01

From a slow start, the clean development mechanism (CDM) market has recently experienced enormous growth. However, the CDM market has been increasingly criticised, resulting in a lively debate about how to reform, complement, or replace it. In order to increase transparency and assist policy-makers in better understanding the current market, we depart from the traditional project-level perspective on CDM and analyse commercial activities by utilising data from UNEP Risoe's CDM Bazaar. To this end, we first establish a seven-step value chain by conducting a factor analysis on the commercial activities indicated in the Bazaar and, second, identify nine prevalent business models with a cluster analysis of all 495 participating organisations. Based on these analyses, we discuss potential impacts on the value chain of different policy scenarios that rely on carbon credits as incentive. We find that the importance of specific regulatory CDM know-how and general business activities such as finance varies strongly with the different policy scenarios. Our analysis serves to sensitise policy-makers and business about implications of different regulatory designs.

The Hubble Constant to 1%: Physics beyond LambdaCDM

Science.gov (United States)

Riess, Adam

2017-08-01

By steadily advancing the precision and accuracy of the Hubble constant, we now see 3.4-sigma evidence for a deviation from the standard LambdaCDM model and thus the exciting chance of discovering new fundamental physics such as exotic dark energy, a new relativistic particle, dark matter interactions, or a small curvature, to name a few possibilities. We propose a coordinated program to accomplish three goals with one set of observations: (1) improve the precision of the best route to H_0 with HST observations of Cepheids in the hosts of 11 SNe Ia, lowering the uncertainty to 1.3% to reach the discovery threshold of 5-sigma and begin resolving the underlying source of the deviation; (2) continue testing the quality of Cepheid distances, so far the most accurate and reliable indicators in the near Universe, using the tip of the red giant branch (TRGB); and (3) use oxygen-rich Miras to confirm the present tension with the CMB and establish a future route available to JWST. We can achieve all three goals with one dataset and take the penultimate step to reach 1% precision in H_0 after Gaia. With its long-pass filter and NIR capability, we can collect these data with WFC3 many times faster than previously possible while overcoming the extinction and metallicity effects that challenged the first generation of H_0 measurements. Our results will complement the leverage available at high redshift from other cosmological tools such as BAO, the CMB, and SNe Ia, and will provide a 40% improvement on the WFIRST measurements of dark energy. Reaching this precision will be a fitting legacy for the telescope charged to resolve decades of uncertainty regarding the Hubble constant.

Should developing countries take on binding commitments in a climate agreement? A cost-benefit analysis

International Nuclear Information System (INIS)

Kallbekken, Steffen; Westskog, Hege

2003-01-01

This paper explores the costs and benefits for all parties to a future climate agreement of developing countries taking on binding commitments. Such commitments would allow developing countries to participate in emissions trading, which has significantly lower transaction costs than the present Clean Development Mechanism (CDM). Thus we analyse whether the efficiency gains obtained by participating in emissions trading can offset the economic risk (due to the fact that future emissions cannot be known) incurred by taking on binding commitments. We use a dynamic computable general equilibrium model to carry out the analysis. We find that the efficiency gains that can be obtained by developing countries might not be very large compared to the risks they incur. Developing countries might therefore have good reasons not to embrace ''cap and trade'' emissions trading. (author)

Clinical Predictive Modeling Development and Deployment through FHIR Web Services.

2015-01-01

Clinical predictive modeling involves two challenging tasks: model development and model deployment. In this paper we demonstrate a software architecture for developing and deploying clinical predictive models using web services via the Health Level 7 (HL7) Fast Healthcare Interoperability Resources (FHIR) standard. The services enable model development using electronic health records (EHRs) stored in OMOP CDM databases and model deployment for scoring individual patients through FHIR resources. The MIMIC2 ICU dataset and a synthetic outpatient dataset were transformed into OMOP CDM databases for predictive model development. The resulting predictive models are deployed as FHIR resources, which receive requests of patient information, perform prediction against the deployed predictive model and respond with prediction scores. To assess the practicality of this approach we evaluated the response and prediction time of the FHIR modeling web services. We found the system to be reasonably fast with one second total response time per patient prediction.

Understanding and managing leakage in forest-based greenhouse-gas-mitigation projects.

Schwarze, Reimund; Niles, John O; Olander, Jacob

2002-08-15

A major concern about land use, land-use change and forestry (LULUCF) projects under the Clean Development Mechanism (CDM) is the potential for leakage. Leakage refers to a net increase of greenhouse-gas emissions in an area outside the project resulting from the CDM activity. This paper provides an overview of leakage, its definitions and its causes. It describes ways that LULUCF projects may suffer from leakage and attempts to assess the magnitude of leakage risks for different LULUCF project types. It also summarizes some of the approaches, both in terms of policies and project development, to address LULUCF leakage.

Para isto, realizou-se extensa revisão bibliográfica dos acordos internacionais referentes às mudanças climáticas e de livros e artigos sobre a inserção brasileira no Protocolo de Quioto e no Mecanismo de Desenvolvimento Limpo. O Protocolo de Quioto é um acordo internacional que prevê a redução das emissões de gases de efeito estufa por intermédio de mecanismos flexibilizadores. O Mecanismo de Desenvolvimento Limpo é o único que permite a participação de países em desenvolvimento, para que eles reduzam emissões por meio de projetos que busquem o desenvolvimento sustentável. Neste contexto, o Brasil surge como um país atrativo para o recebimento destes projetos, por sua vocação para desenvolver fontes alternativas de energia e pela sua liderança no processo negociador do Protocolo. O MDL configura-se, portanto, em uma grande oportunidade para o Brasil, visto que esses projetos representam uma fonte de recursos financeiros para que o país busque o desenvolvimento sustentável, além de incentivarem um maior conhecimento científico e a adoção de novas tecnologias.This article intends to study the insertion of Brazil at the Clean Development Mechanism (CDM of the Kyoto Protocol, through clean energy projects, emphasizing the cooperation between developed and developing countries, and aiming the practical actions that this mechanism allows to build up in order to reach the sustainable development and to stop the global warming.

We have reported the isolation of the tetranortriterpenoid 1-cinnamoyl-3,11-dihydroxymeliacarpin (CDM) from partially purified leaf extracts of Melia azedarach L. (MA) that reduced both, vesicular stomatitis virus (VSV) and Herpes simplex virus type 1 (HSV-1) multiplication. CDM blocks VSV entry and the intracellular transport of VSV-G protein, confining it to the Golgi apparatus, by pre- or post-treatment, respectively. Here, we report that HSV-1 glycoproteins were also confined to the Golgi apparatus independently of the nature of the host cell. Considering that MA could be acting as an immunomodulator preventing the development of herpetic stromal keratitis in mice, we also examined an eventual effect of CDM on NF-κB signaling pathway. CDM is able to impede NF-κB activation in HSV-1-infected conjunctival cells and leads to the accumulation of p65 NF-κB subunit in the cytoplasm of uninfected treated Vero cells. In conclusion, CDM is a pleiotropic agent that not only inhibits the multiplication of DNA and RNA viruses by the same mechanism of action but also modulates the NF-κB signaling pathway

Recent astronomical discoveries of supermassive black holes (quasars), gamma-bursters, super-novae, and dust at high redshifts, z = (5-10), are reviewed. Such a dense population of the early universe is at odds with the conventional mechanisms of its possible origin. Similar data from the contemporary universe, which are also in conflict with natural expectations, are considered too. Two possible mechanisms are suggested, at least one of which can potentially solve all these problems. As a by-product of the last model, an abundant cosmological antimatter may be created.

Recent developments in quantum mechanics

It is essentially a review of recent progress in Quantum Mechanics obtained by the ''Geneva School'', put all together in a synthesis for the first time. During these twelve last years Quantum Mechanics has developed deeply in three aspects: 1) the interpretation has been completely clarified but many ''senior'' physicists delight in the mystery of their school-days Quantum Mechanics and do not want to change their minds. 2) The formalism has been developed and generalized to many (if it is not all) physical situations. 3) Many new rules of calculation have been developed. In conclusion many paradoxes and/or unsolved problems have been solved and many calculations which usually appear just as tricks can be explained and justified. I want here to give a brief survey of each one of these three points and to end by some examples which show the power and the efficiency of this new theory. (orig.)

Failure Predictions for VHTR Core Components using a Probabilistic Contiuum Damage Mechanics Model

Energy Technology Data Exchange (ETDEWEB)

Fok, Alex

2013-10-30

The proposed work addresses the key research need for the development of constitutive models and overall failure models for graphite and high temperature structural materials, with the long-term goal being to maximize the design life of the Next Generation Nuclear Plant (NGNP). To this end, the capability of a Continuum Damage Mechanics (CDM) model, which has been used successfully for modeling fracture of virgin graphite, will be extended as a predictive and design tool for the core components of the very high- temperature reactor (VHTR). Specifically, irradiation and environmental effects pertinent to the VHTR will be incorporated into the model to allow fracture of graphite and ceramic components under in-reactor conditions to be modeled explicitly using the finite element method. The model uses a combined stress-based and fracture mechanics-based failure criterion, so it can simulate both the initiation and propagation of cracks. Modern imaging techniques, such as x-ray computed tomography and digital image correlation, will be used during material testing to help define the baseline material damage parameters. Monte Carlo analysis will be performed to address inherent variations in material properties, the aim being to reduce the arbitrariness and uncertainties associated with the current statistical approach. The results can potentially contribute to the current development of American Society of Mechanical Engineers (ASME) codes for the design and construction of VHTR core components.

Around the Way: Testing ΛCDM with Milky Way Stellar Stream Constraints

Science.gov (United States)

Dai, Biwei; Robertson, Brant E.; Madau, Piero

2018-05-01

Recent analyses of the Pal 5 and GD-1 tidal streams suggest that the inner dark matter halo of the Milky Way is close to spherical, in tension with predictions from collisionless N-body simulations of cosmological structure formation. We use the Eris simulation to test whether the combination of dissipative physics and hierarchical structure formation can produce Milky Way–like galaxies whose dark matter halos match the tidal stream constraints from the GD-1 and Pal 5 clusters. We use a dynamical model of the simulated Eris galaxy to generate many realizations of the GD-1 and Pal 5 tidal streams, marginalize over observational uncertainties in the cluster galactocentric positions and velocities, and compare with the observational constraints. We find that the total density and potential of Eris contributed by baryons and dark matter satisfies constraints from the existing Milky Way stellar stream data, as the baryons both round and redistribute the dark matter during the dissipative formation of the galaxy, and provide a centrally concentrated mass distribution that rounds the inner potential. The Eris dark matter halo or a spherical Navarro–Frenk–White dark matter work comparably well in modeling the stream data. In contrast, the equivalent dark matter–only ErisDark simulation produces a prolate halo that cannot reproduce the observed stream data. The ongoing Gaia mission will provide decisive tests of the consistency between {{Λ }}{CDM} and Milky Way streams, and should distinguish between models like Eris and more spherical halos.

Understanding the mechanism of base development of HSQ

Energy Technology Data Exchange (ETDEWEB)

Kim, Jihoon; Chao, Weilun; Griedel, Brian; Liang, Xiaogan; Lewis, Mark; Hilken, Dawn; Olynick, Deirdre

2009-06-16

We study the dissolution mechanism of HSQ (hydrogen silsesquioxane) in base solutions with the addition of chloride salts to elucidate the development mechanism. Reaction mechanisms are proposed based on the dissolution mechanism of quartz. Development kinetics points to two dose-dependent development mechanisms. Considering ion sizes, both hydrated and non-hydrated, and ion exchange, we propose that a combination of a surface dominated reaction at higher doses and a matrix dominated reaction at lower doses accounts for the high development contrast with a NaOH base/NaCl salt mixture. The interplay between the hydrated and non-hydrated ion size leads to higher contrast developers, such as tetramethyl ammonium hydroxide (TMAH) with NaCl.

Full Text Available The Clean Development Mechanism (CDM of the Kyoto Protocol, allows the non Annex 1 countries to receive projects that contribute to reducing greenhouse gas emissions and sustainable development in developing countries. The CDM, since its inception, has issued credits equivalent to 1.434.737.562 tons of CO2, distributed across 7.450 projects around the world, from 15 different sectors. Sectors 14 that allow forestry projects (such as reforestation and afforestation have registered 53 projects to date; 19 of which are in Latin America. Nevertheless, the contribution of this sector currently represents less than 1% of CDM Certificates of Emissions Reduction (CERs issued. In September 2013, through their National Forestry Financing Fund (FONAFIFO, Costa Rica registered their first CDM project with the United Nations Framework Convention on Climate Change (UNFCCC, after having complied with all the project cycle processes. The project, known as "Carbon Sequestration in Small and Medium Farms, Brunca Region, Costa Rica" was a project executed by FONAFIFO under their Environmental Services Payment Program. This project was developed in Pérez Zeledón, San José, Costa Rica in partnership with the Cooperative Corporation CoopeAgri RL. The total goal of the project is to reduce the greenhouse gas emission by 176,050 ton of CO2-e, in a period of 20 years and commercialize the CERs in the regulated carbon market.

Project-Based Emissions Trading. The Impact of Institutional Arrangements on Cost-Effectiveness

2001-01-01

In this paper we demonstrate that the institutional arrangement (or: design) of Joint Implementation (JI) and the Clean Development Mechanism (CDM) has a decisive impact on their cost-effectiveness. We illustrate our arguments by statistically analyzing the costs from 94 Activities Implemented Jointly (AIJ) pilot phase projects as well as by adjusting these data on the basis of simple mathematical formulas. These calculations explicitly take into account the institutional differences between JI (sinks, no banking) and the CDM (banking, no sinks) under the Kyoto Protocol and also show the possible effects on credit costs of alternative design options. However, our numerical illustrations should be viewed with caution, because AIJ is only to a limited extent representative of potential future JI and CDM projects and because credit costs are not credit prices. Some of the main figures found in this study are: an average cost figure per unit of emission reduction for AIJ projects of 46 dollar per ton of carbon dioxide equivalent ($/Mg CO 2 -eq), an average potential JI credit cost figure which is lowered to 37 $/Mg CO 2 -eq by introducing banking and an average of 6 $/Mg CO 2 -eq per credit for potential low-cost CDM projects which includes sinks. However, at CoP6 in November 2000 in The Hague (The Netherlands), the Parties to the Framework Convention on Climate Change (FCCC) did not (yet) reach consensus on the institutional details of the project-based mechanisms, such as the possible arrangement of early JI action or the inclusion of sinks under the CDM. 55 refs

Flexible mechanisms in the corporate greenhouse: implementation of the Kyoto Protocol and the globalization of the electric power industry

The contradictions and unresolved tensions between economic globalization and climate change negotiations have added urgency to the climate change debate. The paper argues that the declining role of the nation state in the global economy and the increasing reach of transnational corporations throughout the world present a serious challenge to the environmental integrity and success of international environmental treaties such as the Kyoto Protocol. In particular efficacy and equity of the flexible mechanism under the Kyoto Protocol are questioned as illustrated by the patterns of Foreign Direct Investment (FDI) of the US electric power industry in the developing world. US FDI in the electric power sectors of developing countries supports continued carbon-intensive development patterns which will make the long-term goals of the Kyoto Protocol more difficult to achieve. Consequently, FDI raises questions about justifiability of giving credit to Annex I countries through CDM projects undertaken by transnational electric power corporations. 13 refs.

Nuclear power for greenhouse gas mitigation

International Nuclear Information System (INIS)

Rogner, H.-H.

2000-11-01

The possibility of global climate change resulting from an increase in greenhouse gas (GHG) concentrations in the atmosphere is a major global concern. At the Third Conference of the Parties (CoP 3) to the United Nations Framework Convention on Climate Change (UNFCCC) held at Kyoto, in December 1997, industrialized countries agreed to accept binding commitments that would reduce their collective GHG emissions, in the 2008-2012 commitment period, by at least 5% below 1990 levels. These countries also agreed to make demonstrable progress towards reducing GHG emissions by 2005. Because climate change is a global problem, i.e. it does not matter where on the globe GHGs are emitted - they all end up in the same atmosphere, many market economists maintain that mitigation should first occur wherever it is cheapest. Thus Article 12 of the Kyoto Protocol makes provisions by which whose signatories who are required to limit emissions can gain credit for financing cost-effective mitigation projects in developing countries, while at the same time promoting sustainable development through the provision of financial and technical assistance. This option is known as the Clean Development Mechanism (CDM). The CDM could be of particular interest to developing countries, which are not subject to emission limitations in the Kyoto Protocol. For example, the use of capital-intensive nuclear power instead of less costly coal-fired electricity generation would result in a significant reduction in GHG emissions. Because many developing countries may not be able to afford the higher investments associated with a nuclear power project, or because nuclear may simply not be the least-cost generation option for a given country, CDM offers an opportunity for (incremental) capital and technology transfer sponsored by countries of the CoP 3 in exchange for GHG emission credits. The benefit to the sponsor would be compliance with the emission limits set out in the Protocol, at a lower cost than if

Bhutan's energy and environmental situation and approaches to development are reviewed and analyzed in this paper. Conservation of natural resources and human happiness have been placed as central strategic policy themes and have been given high priority in the national development plans of Bhutan. Bhutan's unique approach to development via Gross National Happiness (GNH) or the Middle Path of development is being facilitated by the Royal Government of Bhutan as a tool to balance poverty alleviation, environmental conservation and development. However, challenges exist due to the constraints of resources, good governance, legal frameworks, and human capacity. This paper reviews selected sustainable energy projects (e.g. energy from renewables or energy conservation) in Bhutan and finds that in fact, Bhutan's renewable energy resources (e.g. water and forests) which have proved to be indispensable for development are vulnerable due to the adverse impacts of climate change and environmental degradation. Appropriate measures in order to reduce potential environmental degradation and mitigate climate change impacts have been acknowledged globally and these have potential for application in Bhutan. For example, implementation of sustainable energy projects under the Clean Development Mechanism (CDM) of the Kyoto Protocol could offer an opportunity for mitigating climate change impacts and also contributing to sustainable development.

Hydropower may produce more greenhouse gases

International Nuclear Information System (INIS)

Kolshus, Hans H.; Folkestad, Tonje

2002-01-01

According to this article, dam projects in hydropower development may lead to increased emission of greenhouse gases and may create great inconveniences for the local community. Hence it is not without problems to sponsor such projects through the Clean Development Mechanism (CDM) of the Kyoto Protocol. In many countries the great era of hydroelectric development is over and the potential is now in the developing countries. The aim of the CDM is two-fold: sustainable development in the developing countries, and cheap reduction of greenhouse gas emission from developed nations. It has been agreed upon in the climate negotiations that it is the developing country receiving the investments that shall document that the projects conform to the goal of sustainable development of that country. The concept of sustain ability is a vague one, and it is a great challenge to make it more precise so that requirements may be posed on CDM projects. This is important as projects that are suitable from a climate point of view may have undesirable environmental or social effects, which may be in conflict with the goal of sustainable development. This also pertains to hydropower. It also appears that water reservoirs are not always as clean as has been assumed

The Clean Development Mechanism and Sustainable Development in China's Electricity Sector

The Clean Development Mechanism,a flexibility mechanism contained in the Kyoto Protocol, offers China an important tool to attract investment in clean energy technology and processes into its electricity sector. The Chinese electricity sector places centrally in the country's economy and environment, being a significant contributor to the acid rain and air pollution problems that plague many of China's cities and regions, and therefore a focus of many related energy and environmental policies.China's electricity sector has also been the subject of a number of economic analyses that have showed that it contains the highest potential for clean energy investment through the Clean Development Mechanism of any economic sector in China. This mechanism, through the active participation from investors in more industrialized countries, can help alleviate the environmental problems attributable to electricity generation in China through advancing such technology as wind electricity generation, dean coal technology, high efficient natural gas electricity generation, or utilization of coal mine methane. In this context, the Clean Development Mechanism also compliments a range of environmental and energy policies which are strategizing to encourage the sustainable development of China's economy.

Cooperation mechanisms of the EU renewable energy directive and flexible mechanisms of the Kyoto Protocol: comparison and lessons learnt. Working paper

Frieden, Dorian; Tuerk, Andreas; Steiner, Daniel

2013-07-15

This working paper discusses similarities and differences between the cooperation mechanisms of the EU renewable energy directive (RES directive) and the flexible mechanisms of the Kyoto Protocol. The cooperation mechanisms allow the (virtual) trade of renewable energy and were introduced with the RES directive to provide Member States (MS) with greater flexibility to achieve their national targets for renewable energy sources (RES). A similar kind of flexibility is known from the flexible mechanisms of the Kyoto Protocol which aim at the cost efficient achievement of emission reduction targets. Lessons learned from the Kyoto mechanisms may allow conclusions to be drawn on the design and implementation of the renewable energy cooperation mechanisms. This paper first gives an overview of the cooperation mechanisms regarding their potential, advantages and disadvantages, barriers and preconditions. This is followed by a brief explanation of and a systematic comparison with the flexible mechanisms of the Kyoto Protocol – Joint Implementation (JI); Clean Development Mechanism (CDM); and International Emissions Trading (IET). A gamut of factors influenced the success of the Kyoto mechanisms in general and in specific national contexts. Therefore, it is not possible to directly transfer past experiences with the Kyoto mechanisms to the capability of specific nations to make use of the renewable energy cooperation mechanisms. A comparison of specific features, such as the mechanism type (transfer, project-based, support scheme), price building and specific barriers can, however, help anticipate the possible dynamics and challenges of the cooperation mechanisms. Experiences with the Kyoto mechanisms show that predictions based on supply-demand analysis were valid only to a limited extent and that specific factors such as institutional capacity constraints or legal uncertainties delayed or prevented the use of the mechanisms in some cases. Similarly, for the cooperation

Kyoto protocol is a foundation for achieving an ultimate goal of UNFCCC, which is to stabilizing greenhouse gas concentration in the air. The clean development system is a core element for successful implementation of Kyoto protocol with other Kyoto mechanisms. While UNFCCC requires a new paradigm changing to sustainable development considering demand and future environment from the past supply-oriented resource consumption, the clean development system will be used as a means of successful establishment of a new paradigm in 21st century. As environmental problem is integrated with economic problem and each country is thriving for securing its own economic benefit in the issue of environmental conservation, Korea should do its best to have both of global environmental conservation and economic benefit for its own. 1 tab.

A feasibility study is conducted on the assumption of introducing Japan's energy-saving technology into three leading paper and pulp plants in the Philippines for a reduction in greenhouse gas emissions. In the future, the effort will be associated with the clean development mechanism (CDM). The three target plants are TIPCO (Trust International Paper Corporation), UPPC (United Pulp and Paper Co., Inc.), and CCP (Container Corporation of the Philippines). The energy-saving facilities to be installed involve energy-efficient screens, variable-speed motors, conversion of winder unwinding sections into rheostatic brakes, hermetic design for dryer hoods, exhaust heat recovery facilities, etc. A study of the plant and equipment investment standards of the respective corporations indicates that energy-saving alone will not realize a full payback. It will be necessary, therefore, to have the project implemented as a CDM activity for a transfer from the Philippines of some CO2 emission reduced amount credit for Japan to bear a part of the necessary funds. Since the CDM framework and the value of reduced amount credit are not clear at the current stage, negotiations will have to be furthered about Japan's share of funds etc. as soon as the situation becomes clear. Since the Philippine Government is not well-disposed towards CDM, there is no possibility that this project will be approved as a CDM effort. (NEDO)

The Kyoto Protocol, of 1997, foresaw three mechanisms by means of which the market could contribute for the reduction of emissions of greenhouse gases worldwide. The only one of these mechanisms that allows the participation of the countries not listed in the Annex I of the United Nations Framework Convention on Climate Change is the Clean Development Mechanism - CDM. CDM is an important opportunity for these countries to develop projects of emissions reduction and to generate incomes to be applied in projects of sustainable social and environmental improvements. This article offers an analysis of the antecedents and the results of the first auction of Certified Emission Reductions (CER) carried out in Brazil, by 'Bolsa de Mercadorias and Futuros - BM and F', in September 26, 2007, in order to demonstrate to the success of the initiative and its utility for the future of the preservation actions and environmental improvements in the country, also displaying the criticisms of some environmentalist sectors due to the multiplication of landfills as result of economic incentive of the CER generation.

A remarkable adsorbent for removal of contaminants of emerging concern from water: Porous carbon derived from metal azolate framework-6.

Science.gov (United States)

Bhadra, Biswa Nath; Jhung, Sung Hwa

2017-10-15

A series of metal-azolate frameworks or MAFs-MAF-4, -5, and -6-were synthesized and pyrolyzed to prepare porous carbons derived from MAFs (CDM-4, -5, -6, respectively). Not only the obtained carbons but also MAFs were characterized and applied for the adsorption of organic contaminants of emerging concern (CECs, including pharmaceuticals and personal care products) such as salicylic acid, clofibric acid, diclofenac sodium, bisphenol-A, and oxybenzone (OXB) from water. CDM-6 was found to be the most remarkable adsorbent among the tested ones (including activated carbon) for all the adsorbates. OXB was taken as a representative adsorbate for detailed adsorption studies as well as understanding the adsorption mechanism. H-bonding (H-acceptor: CDM; H-donor: CECs) was suggested as the principal mechanism for the adsorption of tested adsorbates. Finally, CDMs, especially CDM-6, were suggested as highly efficient and easily recyclable adsorbents for water purification. Copyright © 2017 Elsevier B.V. All rights reserved.

THE GRAVITATIONAL SHEAR-INTRINSIC ELLIPTICITY CORRELATION FUNCTIONS OF LUMINOUS RED GALAXIES IN OBSERVATION AND IN THE ΛCDM MODEL

International Nuclear Information System (INIS)

Okumura, Teppei; Jing, Y. P.

2009-01-01

We examine whether the gravitational shear-intrinsic ellipticity (GI) correlation function of the luminous red galaxies (LRGs) can be modeled with the distribution function of a misalignment angle advocated recently by Okumura et al. For this purpose, we have accurately measured the GI correlation for the LRGs in the Data Release 6 (DR6) of the Sloan Digital Sky Survey (SDSS), which confirms the results of Hirata et al. who used the DR4 data. By comparing the GI correlation functions in the simulation and in the observation, we find that the GI correlation can be modeled in the current ΛCDM model if the misalignment follows a Gaussian distribution with a zero mean and a typical misalignment angle σ θ = 34.9 +1.9 -2.1 degrees. We also find a correlation between the axis ratios and intrinsic alignments of LRGs. This effect should be taken into account in theoretical modeling of the GI and intrinsic ellipticity-ellipticity correlations for weak lensing surveys.

SWOT analyses of the national energy sector for sustainable energy development

Markovska, N.; Taseska, V.; Pop-Jordanov, J.

2009-01-01

A holistic perspective of various energy stakeholders regarding the Strengths, Weaknesses, Opportunities and Threats (SWOTs) of the energy sector in Macedonia is utilized as baseline to diagnose the current state and to sketch future action lines towards sustainable energy development. The resulting SWOT analyses pointed to the progressive adoption of European Union (EU) standards in energy policy and regulation as the most important achievement in the energy sector. The most important problems the national energy sector faces are scarce domestic resources and unfavorable energy mix, low electricity prices, a high degree of inefficiency in energy production and use, as well as insufficient institutional and human capacities. The formulated portfolio of actions towards enabling sustainable energy development urges the adoption of a comprehensive energy strategy built upon sustainability principles, intensified utilization of the natural gas, economic prices of electricity, structural changes in industry, promotion of energy efficiency and renewables, including Clean Development Mechanism (CDM) projects, enforcement of EU environmental standards and meeting the environmental requirements, as well as institutional and human capacity building.

Development of LTCC Materials with High Mechanical Strength

International Nuclear Information System (INIS)

Kawai, Shinya; Nishiura, Sousuke; Terashi, Yoshitake; Furuse, Tatsuji

2011-01-01

We have developed LTCC materials suitable for substrates of RF modules used in mobile phone. LTCC can provide excellent solutions to requirements of RF modules, such as down-sizing, embedded elements and high performance. It is also important that LTCC material has high mechanical strength to reduce risk of fracture by mechanical impact. We have established a method of material design for high mechanical strength. There are two successive steps in the concept to achieve high mechanical strength. The first step is to improve mechanical strength by increasing the Young's modulus, and the second step is either further improvement through the Young's modulus or enhancement of the fracture energy. The developed material, so called high-strength LTCC, thus possesses mechanical strength of 400MPa, which is twice as strong as conventional material whose mechanical strength is approximately 200MPa in typical. As a result, high-strength LTCC shows an excellent mechanical reliability, against the drop impact test for example. The paper presents material design and properties of LTCC materials.

Quantum mechanics a modern development

Ballentine, Leslie E

2015-01-01

Although there are many textbooks that deal with the formal apparatus of quantum mechanics (QM) and its application to standard problems, none take into account the developments in the foundations of the subject which have taken place in the last few decades. There are specialized treatises on various aspects of the foundations of QM, but none that integrate those topics with the standard material. This book aims to remove that unfortunate dichotomy, which has divorced the practical aspects of the subject from the interpretation and broader implications of the theory. In this edition a new chapter on quantum information is added. As the topic is still in a state of rapid development, a comprehensive treatment is not feasible. The emphasis is on the fundamental principles and some key applications, including quantum cryptography, teleportation of states, and quantum computing. The impact of quantum information theory on the foundations of quantum mechanics is discussed. In addition, there are minor revisions ...

Self-organized service negotiation for collaborative decision making.

Science.gov (United States)

Zhang, Bo; Huang, Zhenhua; Zheng, Ziming

2014-01-01

This paper proposes a self-organized service negotiation method for CDM in intelligent and automatic manners. It mainly includes three phases: semantic-based capacity evaluation for the CDM sponsor, trust computation of the CDM organization, and negotiation selection of the decision-making service provider (DMSP). In the first phase, the CDM sponsor produces the formal semantic description of the complex decision task for DMSP and computes the capacity evaluation values according to participator instructions from different DMSPs. In the second phase, a novel trust computation approach is presented to compute the subjective belief value, the objective reputation value, and the recommended trust value. And in the third phase, based on the capacity evaluation and trust computation, a negotiation mechanism is given to efficiently implement the service selection. The simulation experiment results show that our self-organized service negotiation method is feasible and effective for CDM.
