    Alternative motorization technologies have been proposed in order to achieve energy diversification and a reduction in pollutant emissions. Fuel cell vehicles are, among others, at the centre of research carried out by car manufacturers and oil companies. The use of fuel cell vehicles could contribute, first to a less stringent long-term energy dependence of oil importing countries and, second, to pollutant reduction in the transport sector. First of all, we propose the definition of 'innovation' and its treatment in the frame of mainstream economic theories. Then we proceed to a retrospective analysis of diesel motorization of the car market. In the second part of our work, we conduct a survey among French households aiming to obtain up-to-date information about their degree of acceptance of fuel cell technology. We are concerned about highlighting the determining factors of fuel cell vehicle adoption by consumers. For this, we set up a discrete choice model linking the individual decision to the whole group of technical or socio-economical factors and characteristics. Finally, we develop patterns of fuel cell equipment of passenger cars which differ according to type of vehicle and possible purchase assistance. These patterns lead us to the analysis of long-term fuel cell vehicle development on the French car market. (authors)

    The rationale for conducting climate change mitigation studies in the transport sector is on the premise that: The transport sector is the second largest consumer of fossil fuels in the region; The regional transport sector is an area with high opportunity for infrastructural development under UNFCCC financial mechanism; The regional transport sector is crucial in the SADC region for trade and coupled with the Trade Protocol will play a major role in development hence the need to make it efficient in terms of energy demand and provision of services; The sector offers many mitigation options but with a challenge to evaluate their energy saving and GHG saving potential and yet there is need to quantify possible emission reduction for possible future emission trading. This is also a sector with potential to qualify for financing through Clean Development Mechanism (CDM) recently stipulated in the Kyoto Protocol. (au)

    Full Text Available The article analyses the following issues: 1. Performance measurement in literature. The performance measurement has an important role to play in the efficient and effective management of organizations. Kaplan and Johnson highlighted the failure of the financial measures to reflect changes in the competitive circumstances and strategies of modern organizations. Many authors have focused attention on how organizations can design more appropriate measurement systems. Based on literature, consultancy experience and action research, numerous processes have been developed that organizations can follow in order to design and implement systems. Many frameworks have been proposed that support these processes. The objective of such frameworks is to help organizations define a set of measures that reflect their objectives and assess their performance appropriately. 2. Transport sector performance and its impacts measuring. The purpose of transport measurement is to identify opportunities enhancing transport performance. Successful transport sector management requires a system to analyze its efficiency and effectiveness as well as plan interventions if transport sector performance needs improvement. Transport impacts must be measurable and monitorable so that the person responsible for the project intervention can decide when and how to influence them. Performance indicators provide a means to measure and monitor impacts. These indicators essentially reflect quantitative and qualitative aspects of impacts at given time and places. 3. Transport sector output and input. Transport sector inputs are the resources required to deliver transport sector outputs. Transport sector inputs are typically: human resources, particularly skilled resources (including specialists consulting inputs; technology processes such as equipment and work; and finance, both public and private. 4.

    Today, transport accounts for a quarter of Sweden's energy consumption which consists almost exclusively of fossil fuels. But with the increasing demands for reduced emissions of greenhouse gases, the sector's conversion to other fuels or energy sources will have a major impact the next years. This situation is expected to expand the requirements for statistics of energy consumption of the transport sector. The publication is divided into two parts. Chapter 2 describes the official energy statistics for the transport sector and Chapter 3 presents a breakdown of energy use in passenger and freight services for the respective modes.

    This article investigates possible evolution pathways for the transport sector during the 21st century, globally and in Europe, under a climate change control scenario. We attempt to shed light on the question how the transport sector should best be decarbonized. We perform our study with the global bottom-up energy systems model TIAM-ECN, a version of the TIAM (TIMES Integrated Assessment Model) model that is broadly used for the purpose of developing energy technology and climate policy scenarios, which we adapted for analyzing in particular the transport sector. Given the global aggregated perspective of TIAM-ECN, that in its current version yields at every point in time a single CO2 price for different forms of energy use across geographic regions and economic sectors, it generates a decarbonization process that for the transport sector occurs later in time than for the power sector. This merely reflects that emission reductions are generally cheaper for electricity production than for transportation, and that it is thus cost-minimizing to spend limited financial resources available for CO2 emissions abatement in the power sector first. In our scenarios the use of hydrogen in internal combustion engines and fuel cells, rather than electricity as energy carrier and batteries to store it, gradually becomes the dominant transport technology. This outcome is in agreement with some recent publications but is at loggerheads with the current popularity of the electric car. Based on sensitivity analysis we conclude that even if the establishment of a hydrogen infrastructure proves about an order of magnitude more costly than modeled in our base case, electricity based transportation only broadly emerges if simultaneously also the costs of electric cars go down by at least 40% with respect to our reference costs. One of the explanations for why the electric car is today, by e.g. entrepreneurs, often considered the supposed winner amongst multiple future transportation

    2007-03-20

    A hybrid hydrogen-carbon (H(2)CAR) process for the production of liquid hydrocarbon fuels is proposed wherein biomass is the carbon source and hydrogen is supplied from carbon-free energy. To implement this concept, a process has been designed to co-feed a biomass gasifier with H(2) and CO(2) recycled from the H(2)-CO to liquid conversion reactor. Modeling of this biomass to liquids process has identified several major advantages of the H(2)CAR process. (i) The land area needed to grow the biomass is transportation sector. (ii) Whereas the literature estimates known processes to be able to produce approximately 30% of the United States transportation fuel from the annual biomass of 1.366 billion tons, the H(2)CAR process shows the potential to supply the entire United States transportation sector from that quantity of biomass. (iii) The synthesized liquid provides H(2) storage in an open loop system. (iv) Reduction to practice of the H(2)CAR route has the potential to provide the transportation sector for the foreseeable future, using the existing infrastructure. The rationale of using H(2) in the H(2)CAR process is explained by the significantly higher annualized average solar energy conversion efficiency for hydrogen generation versus that for biomass growth. For coal to liquids, the advantage of H(2)CAR is that there is no additional CO(2) release to the atmosphere due to the replacement of petroleum with coal, thus eliminating the need to sequester CO(2).

  17. Natural gas in the transportation sector

    Ask, T Oe; Einang, P M; Stenersen, D [MARINTEK (Norway)

    1996-12-01

    The transportation sector is responsible for more than 50% of all oil products consumed, and it is the fastest growing oil demand sector and the fastest growing source of emissions. During the last 10 years there have been a considerable and growing effort in developing internal combustion gas engines. This effort has resulted in gas engines with efficiencies comparable to the diesel engines and with emissions considerably lower than engines burning conventional fuels. This development offers us opportunities to use natural gas very efficiently also in the transportation sector, resulting in reduced emissions. However, to utilize all the built in abilities natural gas has as engine fuel, the natural gas composition must be kept within relatively narrow limits. This is the case with both diesel and gasoline today. A further development require therefore specified natural gas compositions, and the direct use of pipeline natural gas as today would only in limited areas be acceptable. An interesting possibility for producing a specified natural gas composition is by LNG (Liquid Natural Gas) production. (EG)

    The fact that the transport sector is growing quickly brings advantages, such as quick access to any geographical location on earth, but also disadvantages: noise, congestion and polluting emissions such as carbon dioxide (CO 2 ), the greenhouse gas (GHG) primarily responsible for global warming. In the effort to bring GHG emissions under control, improving results in the transport sector is a prime long-term objective. What proportion of CO 2 emissions generated at global and national level are due to the road, air, maritime and rail transport sectors, respectively? What mechanisms can be used to reduce GHG emissions in the transport sector at large?

  1. Hydrogen infrastructure for the transport sector

    2007-01-01

    The aim of this paper is to review the factors already discussed in the literature and identify gaps or issues which seem to require further debate in relation of the introduction of hydrogen in the transport sector. Studies in the academic and grey literature have analysed transport systems with a rather wide range of hydrogen penetration rates, utilisation of the infrastructure, hypotheses on the dynamics of the systems, capital costs of the infrastructure and hydrogen price. Most of the issues which could widen the debate in the literature are related to policy instruments. In particular, more attention should be paid to the policy instruments needed to foster co-ordination among stakeholders, persuade drivers to buy hydrogen vehicles despite the existence of a sparse infrastructure; guarantee investment in the early, possibly loss-making, retail stations and to foster financially sustainable government commitments. The effect of limited availability of hydrogen vehicle models on the penetration rates in the literature and the sensitivity of the hydrogen price to taxation from the government are other two issues deserving a more in-depth discussion.

    In this study we have analysed different options to apply emissions trading for greenhouse gas emissions to the transport sector. The main focus has been on the EU transport sector and the possibility to include it in the current EU ETS in the trading period beginning in 2013. The purpose was to study how different alternatives will affect different actors. Focus has been on three sub-sectors; road transport, aviation and shipping. The railway sector has only been treated on a general level. The study includes the following three parts: 1. An economic analysis of the consequences of greenhouse gas emissions trading for the transport sector including an analysis of how the total cost for reaching an emission target will be affected by an integrated emissions trading system for the transport sector and the industry (currently included sectors) compared to separate systems for the sectors, 2. An analysis of design possibilities for the different sub-sectors. Discussion of positive and negative aspects with different choices of design parameters, such as trading entity, covered greenhouse gases, allocation of emission allowances and monitoring systems, 3. Examination of the acceptance among different actors for different options of using greenhouse gas emissions trading in the transport sector. When setting up an emissions trading scheme there are a number of design parameters that have to be analysed in order to find an appropriate system, with limited administrative and transaction costs and as small distortions as possible to competitiveness

    Full Text Available Psychotic disorders are among the most complex medical conditions. Longitudinal cohort studies may offer further insight into determinants of functional outcome after a psychotic episode. This paper describes the Psychosis Recent Onset in GRoningen Survey (PROGR-S that currently contains data on 1076 early-episode patients with psychosis, including symptoms, personality, cognition, life events and other outcome determinants. Our goal in this report is to give an overview of PROGR-S, as a point of reference for future publications on the effect of cognition, personality and psychosocial functioning on outcomes. PROGR-S contains an extensive, diagnostic battery including anamnesis, biography, socio-demographic characteristics, clinical status, drug use, neuropsychological assessment, personality questionnaires, and physical status tests. Extensive follow-up data is available on psychopathology, physical condition, medication use, and care consumption. Sample characteristics were determined and related to existing literature. PROGR-S (period 1997-2009, n = 718 included the majority of the expected referrals in the catchment area. The average age was 27 (SD = 8.6 and two-thirds were male. The average IQ was lower than that in the healthy control group. The majority had been diagnosed with a psychotic spectrum disorder. A substantial number of the patients had depressive symptoms (479/718, 78% and current cannabis or alcohol use (465/718, 75%. The level of community functioning was moderate, i.e. most patients were not in a relationship and were unemployed. The PROGR-S database contains a valuable cohort to study a range of aspects related to symptomatic and functional outcomes of recent onset psychosis, which may play a role in the treatment of this complex and disabling disorder. Results reported here show interesting starting points for future research. Thus, we aim to investigate long-term outcomes on the basis of cognition, personality, negative

    Full text: Maintenance is a critical issue for fusion DEMO reactor because the design conditions and requirements of DEMO maintenance scheme are different from that of ITER remote handling. The sector transport maintenance scheme has advantages to maintain blankets and divertors without the use of sophisticated remote handling devices including sensitive devices to radiation in the reactor. SlimCS designed in JAEA adopts the sector transport maintenance scheme in which every sector is pulled out horizontally through a port between TF coils. A critical design issue for the horizontal sector transport maintenance scheme is how to support an enormous turnover force of the toroidal field (TF) coils. We propose following two options; first option is the horizontal transport maintenance scheme in which every sector is pulled out through four horizontal ports connected with the corridor. Second option is the vertical sector transport maintenance scheme with small vertical maintenance ports (total: 6 ports). The new horizontal sector transport limited in the number of maintenance ports is a more realistic maintenance scheme, and the key engineering issue is the transferring mechanism of sector in the vacuum vessel. In the maintenance scenario, the key design factors are the cool down time in reactor and the cooling method in maintenance scheme for keeping components under operation temperature. By one-dimensional heat conduction analysis, the sector should be transported to hot cell within 40 hours in the case the cool down time is one month. In the horizontal sector transport maintenance, the maintenance time including removal of cooling piping, drain of cooling water and sector transport to hot cell is about 32 hours. Furthermore, the tritium release in the sector transport can be suppressed because the components temperature drops by forced-air cooling system. This paper mainly focuses on a sector transport maintenance scheme from the aspects of high plant availability

  7. Energy and exergy utilization in transportation sector of Saudi Arabia

    2004-01-01

    In this paper we present an analysis of energy and exergy utilization in the transportation sector of Saudi Arabia by considering the sectoral energy and exergy flows for the years of 1990-2001. Energy and exergy analyses are conducted for its three subsectors, namely road, air and marine, and hence the energy and exergy efficiencies are obtained for comparison. Road subsector appears to be the most efficient one compared to air and marine subsectors. It is found that the energy efficiencies in air and marine subsectors are found to be equal to the corresponding exergy efficiencies due to the values of exergy grade function. A comparison of the overall energy and exergy efficiencies of Saudi Arabian transportation sector with the Turkish transportation sector is also presented for the year 1993 based on the data available. Although the sectoral coverage is not same for both countries, it is still useful to illustrate the situation on how subsectoral energy and exergy efficiencies vary over the years. Turkish transportation sector appears to be a bit more efficient for that particular year. It is believed that the present technique is practical and useful for analyzing sectoral energy and exergy utilization to determine how efficient energy and exergy are used in transportation sector. It is also be helpful to establish standards, based on exergy, to facilitate applications in industry and in other planning processes such as energy planning

    Transport energy use in Sweden increased by 80% during the period 1970 to 2008. Today, the transport sector is responsible for a quarter of Sweden's energy use. Since the transport sector is almost exclusively using fossil fuels its conversion to other fuels/energy sources will have a major impact in the coming years, with the increasing requirements to reduce emissions of greenhouse gases. The first chapter reports the official energy statistics for the transport sector. The second chapter presents a breakdown of energy use for freight and passengers for each transport modes. However, it is important to emphasize that the division of personal and freight does not belong to the official energy statistics

  14. Measuring Energy Efficiency in China’s Transport Sector

    Full Text Available Energy efficiency is one of the key factors affecting energy consumption and greenhouse gas (GHG emissions. By focusing on China’s transport sector, this study comprehensively reviews and compares the energy efficiency performance of passenger vehicles, light-duty commercial vehicles, commercial road transport, commercial water transport, aviation transport and railway transport, and identifies the opportunities for further energy efficiency improvements. It is found that railway transport exhibited the greatest improvement in energy efficiency during the past decade, which was mainly driven by progress in its electrification. Passenger vehicles have also experienced considerable energy efficiency improvements, which can be mainly attributed to the establishment of mandatory fuel consumption standards. In contrast, commercial road transport has shown the least improvement, due to insufficient policy implementations. Based on the analysis, it is recommended that, as China’s present policy framework to improve energy efficiency in the transport sector is generally effective, it should be consistently maintained and successively improved. Electrification represents a major opportunity for improvement of energy efficiency in the transport sector. Such potential should be fully tapped for all transport modes. Greater effort should be put into improving the energy efficiency of commercial road transport. The policy instruments utilized to improve the energy efficiency of heavy-duty vehicles should be as intensive and effective as the policy instruments for passenger vehicles.

    Within the European framework, France has committed to a 20% reduction of its GHG emission by 2020 compared with 1990, and reaching the 'factor 4' by 2050. The 2005 POPE Act (the French Energy Policy Guidance Act) makes climate change a priority of the energy policy, setting out a 3% yearly reduction of our country's GHG emissions. This means combining energy efficiency and restraint, as is highlighted by the first chapter of the 'energy transition road-map'. Energy is a major component of transport. Designing its transition requires us to question the very organisation of our society: materials and their usage, the means of transport to favour and the infrastructures to implement, costs for competitiveness, the organisation of work and commuting... At a global scale, needs for mobility are increasing, as is the urgent need to deal with environmental problems. There are huge emerging markets for public transport, increasingly efficient and smart cars, information and transmission networks, infrastructures, the organisation of transport... However, France has all the assets to become a world leader in carbon-free transport. Succeeding in this change means organising the service to meet the needs of all, people, businesses, transport operators and industry, starting this transition right away. Policies must clearly define objectives and the means of achieving them through coordinated actions within a long term approach. The ESEC formulates a set of proposals in this direction

  16. INTRODUCTION OF A SECTORAL APPROACH TO TRANSPORT SECTOR FOR POST-2012 CLIMATE REGIME

    Directory of Open Access Journals (Sweden)

    Atit TIPPICHAI

    2009-01-01

    Full Text Available Recently, the concept of sectoral approaches has been discussed actively under the UNFCCC framework as it could realize GHG mitigations for the Kyoto Protocol and beyond. However, most studies have never introduced this approach to the transport sector explicitly or analyzed its impacts quantitatively. In this paper, we introduce a sectoral approach which aims to set sector-specific emission reduction targets for the transport sector for the post-2012 climate regime. We suppose that developed countries will commit to the sectoral reduction target and key developing countries such as China and India will have the sectoral no-lose targets — no penalties for the failure to meet targets but the right to sell exceeding reductions — for the medium term commitment, i.e. 2013–2020. Six scenarios of total CO2 emission reduction target in the transport sector in 2020, varying from 5% to 30% reductions from the 2005 level are established. The paper preliminarily analyzes shares of emission reductions and abatement costs to meet the targets for key developed countries including the USA, EU-15, Russia, Japan and Canada. To analyze the impacts of the proposed approach, we generate sectoral marginal abatement cost (MAC curves by region through extending a top-down economic model, namely the AIM/CGE model. The total emission reduction targets are analyzed against the developed MAC curves for the transport sector in order to obtain an equal marginal abatement cost which derives optimal emission reduction for each country and minimizes total abatement cost. The results indicate that the USA will play a crucial role in GHG mitigations in the transport sector as it is most responsible for emission reductions (i.e. accounts for more than 70% while Japan will least reduce (i.e. accounts for about 3% for all scenarios. In the case of a 5% reduction, the total abatement is equal to 171.1 MtCO2 with a total cost of 1.61 billion USD; and in the case of a 30

This is a new challenge, as previously improving transport generally led to increased greenhouse gases. The challenge now is to provide transport that: 1) is cheaper, more extensive and better quality 2) reduces pollution, congestion, traffic accidents and other threats to health and wellbeing 3) is accessible to all 4) supports economic development 5) reduces greenhouse emissions overall. This can be achieved if: 1) mass transit, walking and cycling are supported and encouraged, and integrated in a way that allows seamless multimodal travel, including networks of taxis, auto-rickshaws and small buses. 2) the mass transit services - including trains, buses and light-rail - are frequent, extensive, attractive, comfortable, affordable and faster than alternatives, with features like integrated ticketing and real time information accessible through mobile phones and other sources 3) private vehicle use and air travel are discouraged through pricing and other demand management measures, and through the availability of better alternative modes 4) there is support for the adoption of cleaner, lower carbon fuels and technologies and better maintenance practices for all transport modes, including private vehicles, water transport, auto-rickshaws and freight vehicles 5) the overall need for travel is reduced through the development of denser localities with more mixed land use and better access to mass transit (which reduces overall travel in ways that will be explained) 6) travel space is better managed to give higher priority to more sustainable transport modes, to promote safety, and to prevent traffic from adversely affecting residents and businesses.

    A primary characteristic of transportation in the United States is its high per capita energy consumption. The average US citizen consumes nearly five times as much energy for transportation as the average Japanese and nearly three times as much as the average citizen of France, Britain, or West Germany. The energy efficiency of US transportation has improved substantially over the past two decades (both absolutely and in comparison to Europe), and US travel volume has grown more slowly than in most of the developed world. However, the United States still consumes more than one-third of the world`s transport energy. Also, 96 percent of US transport energy is in the form of oil products. This is more oil than the United States produces, despite its position as one of the world`s largest oil producers. With current problems and expectation of continued growth in travel and energy use, Congress has increasingly turned to transportation energy conservation - in the form of improvements in the technical efficiency of travel, increases in load factors, reductions in travel demand, shifting to alternative fuels, and shifts to more efficient travel modes - as an important policy goal. For example, the Clean Air Amendments of 1990 incorporate transportation demand management as a critical tool in reducing urban air pollution. Legislation proposed in the 102d Congress sought rigorous new automobile and light truck fuel economy standards. With continued increases in U.S. oil imports, urban traffic congestion, and greenhouse gas emissions, and the failure of many urban areas to meet air quality standards, strong congressional interest in new energy conservation initiates is likely to continue.

    Although energy consumption in the industry sector has almost been stable, energy consumption in the transportation (passenger and freight) sector has increased much after the oil crisis. The increase of energy consumption in the passenger sector can be attributed to the increase in transportation by private passenger vehicles; while the increase in the freight sector was due to the modal shift to trucks. Among transportation methods, automobiles, i.e. passenger vehicles and trucks, are now dominant in terms of energy consumption and also in terms of amount of transportation. Therefore implementing energy conservation measures relating to automobiles is very important in order to suppress the energy consumption in the transportation sector. This report summarizes the results of investigation on energy conservation measures, especially relevant to automobiles. It was found from the investigation that most promising and effective technologies or measures are promoting market penetration of vehicles satisfying ''top runner standard'', development and employment of hybrid vehicles, and introduction of vehicles with ''idling-stop'' systems.

    By combustion of fossil fuels; CO{sub 2} is emitted to the atmosphere. The new assessment report from the Intergovernmental Panel on Climate Change (IPCC, 1996) reveals that scientific uncertainty - a major barrier to action - is being steadily reduced. The report goes further than ever before by stating that scientists now believe that `the balance of evidence suggest a discernible human influence on global climate`. This significant conclusion will certainly contribute to mobilizing political support for stronger commitments. Denmark already have decided on strong reduction targets. It is the goal of the government to reduce the CO{sub 2} emissions from the energy consuming sectors by 20% in 2005 compared to 1988 and to reach further reducations up to the year 2030.

    Sweden has set long-term energy policy targets which aim at eliminating net greenhouse gas (GHG) emissions by 2050 [1]. Since the production of power and district heating in Sweden is already close to be carbon neutral, a further reduction of GHG emissions have to be seeked in other sectors......, if the ambitious targets of a carbon neutral transport system by 2050 and of being independent from fossil fuels in the vehicle fleet by 2030 have to be achieved [1]. To meet the energy policy targets, radical restructuring of the fuel use and vehicle stock in the transport sector is required. In this context......, this paper develops two alternative scenarios for the transport sector by 2050 – an Electric Vehicles Scenario (EVS) which include a high percentage of electric vehicles and a BIOfuel Scenario (BIOS) with a high percentage of biofuels.

    Power and heating generation sector and transport sector contribute a highest GHG emissions and even air pollutions. This paper seeks to investigate life cycle costs and emissions in both the power sector and transport sector, and evaluate the cost-emission efficient (costs for one unit GHG emissions) of the substitution between new energy vehicles and conventional gasoline based vehicles under two electricity mix scenarios. In power sector, wind power and PV power will be cost comparative in 2030 forecasted with learning curve method. With high subsidies, new energy cars could be comparative now, but it still has high costs to lower GHG emissions. When the government subsidy policy is reversible, the emission reduction cost for new energy vehicle consumer will be 900/ton. According to the sensitive analysis, the paper suggests that the government implement policies that allocate the cost to the whole life cycle of energy production and consumption related to transport sector energy transition and policies that are in favor of new energy vehicle consumers but not the new energy car producers.

    The diagnostic components that were ordered for the rest of the proposed beamlines at the NAC have been delivered. Design and manufacture of a special harp for the beam swinger has commenced. The Faraday cups and slits in the transfer beamline were replaced by water-cooled versions, owing to the decision to transport beams of higher intensity than initially specified. A prototype water-cooled slit for use in the low-energy beamline emittance measurement system has been installed, replacing the previous uncooled slit, to meet the requirement to measure the emittance of high-intensity beams. Software to automate the emittance measurement procedure is being developed. The method of calibration and alignment of the beamline scanners has been improved resulting in a more accurate measurement of the beam position. Software is being developed to regulate the beam current on the neutron therapy target. Current measurement from the target is used as feedback to regulate the aperture of a slit-system in the low-energy transfer beamline. This procedure will be implemented as soon as final tests have been carried out during the next scheduled shutdown. 3 figs

    2007-01-01

    China is the world's second largest greenhouse gas emitter, and emissions from the road transport sector represent one of the fastest growing GHG sources in China. Taking previous research on China's projected future vehicle ownership and future CO 2 emissions in the transport sector as a starting point, this paper reviews all recent environmental policies relating to the automobile industry and employs a scenario analysis to estimate different emissions inventories for different development strategies. The new policy scenario considers all possible mitigation options available to the road transport sector from a bottom up perspective and examines the effects for fuel efficiency improvement and the cost of these mitigation options - vehicle technology improvement, bus rapid transit system and fuel switching, through which the carbon dioxide emissions reduction potential is estimated. Not only does this paper indicate that a large emissions reduction potential exists in China's road transport sector, but it implies that vehicle technology improvement, especially engine technology is likely to be the most effective means to meet emissions reduction targets. This paper concludes by identifying key barriers to implementing those options in China and deduces the technical, financial and institutional aspects of the demand in China for national capacity building and international aid in order to achieve the emissions reduction goals

    The transportation fuel and energy use estimates developed a Oak Ridge National Laboratory (ORNL) for the End Use Energy Consumption Data Base are documented. The total data base contains estimates of energy use in the United States broken down into many categories within all sectors of the economy: agriculture, mining, construction, manufacturing, commerce, the household, electric utilities, and transportation. The transportation data provided by ORNL generally cover each of the 10 years from 1967 through 1976 (occasionally 1977 and 1978), with omissions in some models. The estimtes are broken down by mode of transport, fuel, region and State, sector of the economy providing transportation, and by the use to which it is put, and, in the case of automobile and bus travel, by the income of the traveler. Fuel types include natural gas, motor and aviation gasoline, residual and diesel oil, liuqefied propane, liquefied butane, and naphtha- and kerosene-type jet engine fuels. Electricity use is also estimated. The mode, fuel, sector, and use categories themselves subsume one, two, or three levels of subcategories, resulting in a very detailed categorization and definitive accounting.

    Full Text Available In the United States, two thirds of the carbon monoxide and about one third of carbon dioxide emissions come from the transportation sector. Ways to reduce these emissions in the future include replacing gasoline and diesel by biofuels, or by blend of biofuels with conventional gasoline and diesel, or by compressed natural gas (CNG, or by replacing internal combustion engines by electric motors powered by hydrogen fuel cells or battery-powered electric vehicles recharged from the electric grid. This presentation will review these technologies the fuel production pathways, when they are likely to be available, and by what fraction transportation sector green house gas emissions could be reduced by each. A well-to-wheels (WTW analysis is performed on each vehicle/ fuel technology using the GREET model and the total energy use, the CO 2 emissions, NO x emissions, SO x emissions for the life cycle of the vehicle technologies are calculated. Prospects for reducing foreign oil dependence as well as mitigating green house gases emission from the transportation sector will be considered in the analysis.

    The Government has introduced a national target for the reduction of CO{sub 2} emissions from the transport sector, which aims to stabilize emissions at the 1988 level, by the year 2005. This target was first formalized in the Government`s 1990 transport action plan, and later repeated in `Traffic 2005`, published in December 1993. The latter document also makes reference to six strategies, which the Government proposed in order to attain the national target. The majority of the transport policy measures will impact on CO{sub 2} emissions from the sector, even if they are targeted at different objectives, e.g. road safety, air pollution, time savings, etc. A long-list of potential measures, which might be adopted with the primary purpose is to reduce CO{sub 2} emissions, has been identified from the six overall strategies. The measures identified have been subjected to detailed analyses, to ascertain all the potential impacts. The main emphasis has been on clarifying the potential efficacy of each of the measures in reducing CO{sub 2} emissions, and the social costs in a wide sense. The analysis assumes that each policy measure is implemented separately. A methodology is developed that presents the respective consequences in commensurate terms. Similar calculations are undertaken for two different combinations of policy measures. (EG)

    1998-01-01

    Automobiles are still increasing in number in Japan. If this continues, CO 2 emissions in this sector may increase through the first half of the 21st century. Consequently, a study of measures for reducing these CO 2 emissions is essential. In this paper, possible automotive technologies, improvements in fuel consumption and the introduction of electric vehicles are discussed. These measures are then evaluated for the Japanese case. Furthermore, market penetration of these technologies is evaluated, using life-cycle cost analysis based on initial cost and annual fuel cost. It is concluded that reducing CO 2 emissions to 1995 levels by 2010 is possible. This would require the simultaneous implementation of fuel-consumption improvements and the introduction of electric vehicles. However, automotive consumers would be reluctant to accept these technologies, particularly electric vehicles, because of their high purchase-price and low benefits in terms of operating economy. Acceptance will require financial and institutional support from the public sector in introducing these automotive technologies into the Japanese transportation sector. (author)

    2007-01-01

    Alternative fuels based on renewable energy sources, such as biodiesel, bioethanol and hydrogen from RES, have potential to reduce greenhouse gas emissions, climate change, to increase supply security and energy diversity. Transition from a fossil fuels based transport to future sustainable and clean transport is a long term and cost intensive process, especially for hydrogen use in transport. Hydrogen infrastructure is missing and most of hydrogen technologies are still at developing stage.This paper examines the economics of biofuels (bioethanol and biodiesel) and hydrogen production from renewable energy sources. The current and future costs of alternative fuels as well as the costs of the provided energy services are analysed in a dynamic framework till the year 2050. The goal is to identify the market chance of alternative fuels in a long term (till 2050). A rapid increase of fuel cell vehicles with hydrogen on the market is not expected before 2030, mainly because the costs of the fuel cells are still very high and because their efficiency, as well as the travelling range, is rather moderate.However, the use of alternative fuels in transport sector is very dependent on the political will. If political preferences, like e.g. zero-emission-vehicles, gain strong relevance this new fuels could accelerate its market penetration significantly

    This paper reports that Pakistan is taking steps to speed expansion of its refining and oil transportation infrastructure. While the country has made significant progress toward energy self-efficiency by boosting oil and gas production it still must modernize and expand an aging, inadequate refining sector to meet rapidly growing demand for refined products. Pakistan's government has disclosed plans to build two refineries in the country, one at Rawalpindi near a string of recent oil discoveries, the other somewhere in the southern part of the country, likely Karachi. At the same time, efforts are proceeding to upgrade Pakistan's refineries.

    Today, the transport sector accounts for a quarter of the Sweden's energy consumption. As the transport sector is almost exclusively using fossil fuels, its conversion to other fuel-/energy types have a major impact in the coming years with the increasing requirements for reduced emissions of greenhouse gases. This situation is expected to change and expand requirements for statistics on the transport sector's energy use. Since 2008, as a result of the increased interest, the Swedish Energy Agency publish an annual collection of statistics for the transport sector.

  1. Biomass-based energy carriers in the transportation sector

    Johansson, Bengt.

    1995-03-01

    The purpose of this report is to study the technical and economic prerequisites to attain reduced carbon dioxide emissions through the use of biomass-based energy carriers in the transportation sector, and to study other environmental impacts resulting from an increased use of biomass-based energy carriers. CO 2 emission reduction per unit arable and forest land used for biomass production (kg CO 2 /ha,year) and costs for CO 2 emission reduction (SEK/kg CO 2 ) are estimated for the substitution of gasoline and diesel with rape methyl ester, biogas from lucerne, ethanol from wheat and ethanol, methanol, hydrogen and electricity from Salix and logging residues. Of the studied energy carriers, those based on Salix provide the largest CO 2 emission reduction. In a medium long perspective, the costs for CO 2 emission reduction seem to be lowest for methanol from Salix and logging residues. The use of fuel cell vehicles, using methanol or hydrogen as energy carriers, can in a longer perspective provide more energy efficient utilization of biomass for transportation than the use of internal combustion engine vehicles. 136 refs, 12 figs, 25 tabs

    Transportation sector is the second most energy consuming sector after industrial sector, accounting for 40% of total energy consumption in Malaysia. The transportation sector is one of the most energy intensive sectors in the country and relies primarily on petroleum products, which in total account for nearly 98% of the total consumption in the sector. Since it is heavily reliant on petroleum based fuels, the sector contributes significantly to the greenhouse gas (GHG) emissions. The need to reduce the greenhouse gas emission is paramount as Malaysia at Conference of the Parties (COP15) pledged to reduce its carbon intensity by 40% by 2020 from 2005 level subject to availability of technology and finance. Transport sector will be among the first sectors that need to be addressed to achieve this goal, as two-thirds of the emissions come from fuel combustion in transport sector. This paper will analyse the factors influencing the transport sector's growth and energy consumption trends and discuss the key issues and challenges for greener environment and sustainable transportation in Malaysia. The paper will also discuss the policy and strategic options aimed towards energy efficient pathways in Malaysia.

  6. Essays on alternative energy policies affecting the US transportation sector

    Science.gov (United States)

    O'Rear, Eric G.

    This dissertation encompasses three essays evaluating the impacts of different policies targeting the greenhouse gas (GHG) emissions, fuel demands, etc. of the transportation sector. Though there are some similarities across the three chapters, each essay stands alone as an independent work. The 2010 US EPA MARKAL model is used in each essay to evaluate policy effects. Essay 1 focuses on the recent increases in Corporate Average Fuel Economy (CAFE) standards, and the implications of a "rebound effect." These increases are compared to a carbon tax generating similar reductions in system-wide emissions. As anticipated, the largest reductions in fuel use by light-duty vehicles (LDV) and emissions are achieved under CAFE. Consideration of the rebound effect does little to distort CAFE benefits. Our work validates many economists' belief that a carbon tax is a more efficient approach. However, because the tax takes advantage of cheaper abatement opportunities in other sectors, reductions in transportation emissions will be much lower than what we observe with CAFE. Essay 2 compares CAFE increases with what some economists suggest would be a much more "efficient" alternative -- a system-wide oil tax internalizing some environmental externalities. Because oil taxes are likely to be implemented in addition to CAFE standards, we consider a combined policy case reflecting this. Our supplementary analysis approximates the appropriate tax rates to produce similar reductions in oil demands as CAFE (CAFE-equivalent tax rates). We discover that taxes result in greater and more cost-effective reductions in system-wide emissions and net oil imports than CAFE. The current fuel tax system is compared to three versions of a national vehicle miles traveled (VMT) tax charged to all LDVs in Essay 3. VMT taxes directly charge motorists for each mile driven and help to correct the problem of eroding tax revenues given the failure of today's fuel taxes to adjust with inflation. Results

  7. Low-Emission Transportation Sector in 2050 - Reality or Utopia

    2016-01-01

    In the European Union, transportation is identified as a consumer with the biggest share in the structure of final energy consumption in 2013. It is also responsible for more than 25 percent of the total carbon dioxide emissions, therefore positioning itself right next to the sector with the highest emissions percentage, energy transformations. Transportation sector is the only one with an increase of CO2 emissions in the last 25 years and that fact clearly shows how necessary it is to implement an unambiguous political framework that will result with the achievement of ambitious, strategic goals of the Union that entail an 80 percent emissions reduction by 2050, compared to 1990. Even though the approach doesn't take into consideration the emission emanated in the energy sources' life span, the calculations in the model attest to the fact that a middle term goal of a 30 percent reduction of greenhouse gas emissions by 2030 (compared to 2005) is achievable (for sectors that aren't included in the emissions trade system), with the condition of achieving borderline goals defined by the current regulations that address road transport emissions. Despite the fact that, during 2015, a number of a million globally registered electric cars was surpassed, their influence on the transport emissions is minimal. For the achievement of the long-term goal, defined in the White Paper (2011, a 60 percent reduction of emissions by 2050), it is necessary to reduce an average TTW emission of the EU fleet to an amount below 40 g/km after 2030. Because of the limiting technological aspect of an internal combustion engine, alternative fuels become more prominent and biofuels of higher generations, fuel cells or batteries that charge on renewable energy are left as the only option. There is no question whether the aforementioned alternatives generate the avoided emissions in the last step of the exploitation because they do, but the results of the total sociological costs in this moment

    International Nuclear Information System (INIS)

    1997-03-01

    In this paper other financial control measures than fuel prices are considered for the transportation sector. The main effect discussed is that of the road pricing system. From the point of view of the CO 2 emission there could be introduced a registration tax for trucks over 4 tons as the higher transport expenditure would tend to reduce road transport demand. EU infrastructure tax directive however recommends taxes for trucks exceeding 12 tons. Road pricing will grow within the categories of lighter trucks but it is only a minor fraction of the total truck expenditure, taking into account fuel tax, weight tax and registration tax. Insurance cost is not included in these consideration. (EG) Prepared for Trafikministeriet. 22 refs

  9. Externalities of the transport sector and the role of hydrogen in a sustainable transport vision

    2008-01-01

    Transport systems perform vital societal functions, but in their present state cannot be considered 'sustainable'. One of the most controversially discussed long-term solutions to climate change and air emission externalities is the introduction of hydrogen as an energy fuel and fuel cell vehicles. In this paper, we integrate the two debates on the sustainability of today's transport systems and on the opportunities, threats and possible transition paths towards a 'hydrogen economy' in road transport. We focus our analysis on developed countries as well as the specific needs of the fast growing markets for car travel in the emerging economies. We conclude that the use of hydrogen can significantly reduce CO 2 emissions of the transport sector, even if taking into account tailpipe and upstream emissions as well as alternative technology developments. Moreover, local air pollutants can be reduced up to 80%. Possible negative impacts, including accident risks, nuclear waste or increased biomass demand, need to be benchmarked against these benefits. Thus, we highlight the need for integrated energy and transport policies and argue for more reflexive and inclusive societal debate about the impacts and beneficiaries of hydrogen transport technologies

    The Autonomous Province of Vojvodina is an Autonomous Province in Serbia and it is an energy-deficient country. The indigenous reserves of oil and gas are limited and the country is heavily dependent on the import of oil. The oil import bill is a serious strain on the country's economy and has been deteriorating the balance of payments situation. The country has become increasingly more dependent on fossil fuels and its energy security hangs on the fragile supply of imported oil that is subject to disruptions and price volatility. The transport sector has a 26% share in the total commercial energy consumption in Vojvodina. About 0.62 million tons of gasoline were consumed by this sector in 2008. Gasoline consumption in the transport sector is also a major source of environmental degradation especially in urban areas. Consequently, Vojvodina needs to develop indigenous, environment-friendly energy resources, such as bioethanol, to meet its transport sector's energy needs. Vojvodina produces about 3 million tons of sugar beet every year. There is a vast potential for bioethanol production from molasses of sugar beet in the country. Bioethanol can be used in transport sector after blending with gasoline, in order to minimize gasoline consumption and associated economical and environmental impacts. This paper presents the assessment of the potential contribution of bioethanol in the transport sector of Vojvodina. It is concluded that 20% of annual gasoline consumption in transport sector could be met from ethanol by the year 2026. (author)

  11. Macroeconomic surroundings of transport and logistics sector in Poland during the global economic crisis

    2012-03-01

    Full Text Available During the last quarter of 2009, Poland has entered a phase of economic growth. Presently, despite the emerging financial problems in the EU zone, positive market sig-nals can still be observed in Poland, for example increase in domestic and external de-mand, incoming orders in the industry sector and production capacity in companies. The-se changes enhance growth of production in the industry and construction sectors, which are perceived as key sectors for generating demand for transport services. Therefore the lack of market signals that indicate economic slowdown means that the conditions for transport and logistics sector development in Poland are not expected to deteriorate. The key threat to the stability of economic growth in Poland, and in consequence to transport and logistics companies, is the excess debt of public finance sector.

    A close connection exists between mobility and the spread of HIV infection. Being away from home and traditional social networks and constraints makes people more likely to have sex partners other than their spouses or regular partners. The transport sector has an important role in facilitating the movement of people. Indeed, improving transport is a developmental goal worldwide, with an efficient transport system seen to be a necessary precondition to economic growth. The role of the transport sector in facilitating the spread of HIV needs to be considered. South Africa has the greatest length of roads, railways, and the most registered vehicles in southern Africa. In 1997, Johannesburg International Airport became Africa's most busy airport. South Africa also has a considerable maritime transport sector. In 1994, an estimated more than 500,000 people were employed in the country's transport sector. The following risk groups must be targeted in order to control the spread of HIV in South Africa: people working in building and maintaining infrastructure; people who work in the railways, roads, airlines, and shipping services; transport sector managers; and passengers.

    Driven by the significant growth freight and passenger transport demand, transport sector has become a sector that is largely responsible for increases in emissions of atmospheric pollutants (NOx, CO, HC, PM2.5) in China. Figuring out the emission trend in China's transport sector has great influence on formulating emission reduction measures in the future. In this work, both on-road and off-road transport emissions in China were estimated from 2015 to 2040 for CO, NOx, HC and PM2.5. The projection was conducted based on on the energy consumption structure forecast from IEA (International Energy Agency), the future national average annual distance traveled per vehicle and fuel consumption per distance derived from simulation results of the Fuel Economy and Environmental Impact (FEEI) model. The results show that the ownership of on-road vehicles in China increases rapidly during 2015 to 2030 and then the growth slows down. Finally, the total amount reaches up to 522 million in 2040 in which 84.5% turns out to be light-duty vehicles. Because current control legislations for the transport sector in China will continue to be strengthened in the future, the total emissions of China's transport sector were projected to peak around 2030, due to the improvement of vehicle emission standard and the retirement of old vehicles are the most effective measures. The off-road transport will become the main contributor to emissions from transport sector in China since 2030. This work provides a new perspective to understand emissions from both on-road and off-road transport in China, which can support the achievement of improving air quality promised by the Chinese government. This work provides a new perspective to understand the emission trends of on-road and off-road transport sector in China from 2015 to 2040, which can support the achievement of the air quality goal promised by the Chinese government.

    Malaysia is paying a high level of subsidies on the consumption of energy (about 5% of its GDP). Therefore, reforming the energy subsidies, as planned by the government, will have a significant impact on household welfare and energy-intensive sectors, such as the transport sector. This study employs a computable general equilibrium (CGE) model to highlight the transmission channels through which the removal of energy subsidies affects the domestic economy. The findings show that the shock increases real GDP and real investment, while decreasing Malaysian total exports and imports. The removal of energy subsidies also decreases the aggregate energy demand, and, consequently, decreases the level of carbon emissions in the Malaysian economy. In addition, households experience significant falls in their consumption and welfare. The transport sector is significantly influenced through an increase in production costs due to an increase in the prices of intermediate inputs. The total output and total exports of the whole transport sector decrease while its imports increase. In addition, the use of all kinds of transport by households decreases significantly. The Malaysian energy subsidy reform, leads to an initial decrease in CO 2 emissions and demand for electricity, gas, and petroleum products in the entire transport sector. - Highlights: • Malaysia pays a high level of subsidy on consumption of energy. • The transportation sector in this country is the highest energy consumer among others. • A general equilibrium model used to analyse the effects of energy subsidy reform. • The shock increases real GDP and decreases energy and carbon emission in this sector. • It is not beneficial for the transport sector as decreases the output of this sector

    2013-01-01

    China is currently in the stage of industrialization and urbanization, which is characterized by rigid energy demand and rapid growth of energy consumption. Therefore, energy conservation will become a major strategy for China in a transition to low-carbon economy. China's transport industry is of high energy consumption. In 2010, oil consumption in transport industry takes up 38.2% of the country's total oil demand, of which 23.6% is taken up by road transport sector. As a result, oil saving in China's road transport sector is vital to the whole nation. The co-integration method is developed to find a long-run relationship between oil consumption and affecting factors such as GDP, road condition, labor productivity and oil price, to estimate oil demand and to predict future oil saving potential in China's transport sector under different oil-saving scenarios. Monte Carlo simulation is further used for risk analysis. Results show that under BAU condition, oil demand of China's road transport sector will reach 278.5 million ton of oil equivalents (MTOE) in 2020. Oil saving potential will be 86 MTOE and 131 MTOE under moderate oil-saving scenario and advanced oil-saving scenario, respectively. This paper provides a reference to establishing oil saving policy for China's road transport sector. - Highlights: • We adopt the co-integration model to estimate oil demand and oil saving potential of China's road transport sector. • Monte Carlo simulation is further used for risk analysis. • GDP, ratio of classified highway, labor productivity and oil price are main factors affecting oil consumption. • Scenario analysis approach is applied to calculate oil saving potential under different energy saving scenarios. • Future policy for oil conservation in China's road transport sector is suggested

    Pakistan is an energy-deficient country. The indigenous reserves of oil and gas are limited and the country is heavily dependent on the import of oil. The oil import bill is a serious strain on the country's economy and has been deteriorating the balance of payments situation. The country has become increasingly more dependent on fossil fuels and its energy security hangs on the fragile supply of imported oil that is subject to disruptions and price volatility. The transport sector has a 28% share in the total commercial energy consumption in Pakistan. About 1.15 million tonnes of gasoline was consumed by this sector during 2005-2006. The gasoline consumption in the transport sector is also a major source of environmental degradation especially in urban areas. Consequently, Pakistan needs to develop indigenous, environment-friendly energy resources, such as ethanol, to meet its transport sector's energy needs. Pakistan produces about 54 million tonnes of sugarcane every year. The estimated production potential of ethanol from molasses is about 500 million liters per annum. Ethanol can be used in the transport sector after blending with gasoline, in order to minimize the gasoline consumption and associated economical and environmental impacts. This paper presents the assessment of the potential contribution of ethanol in the transport sector of Pakistan. It is concluded that 5-10% of the annual gasoline consumption in transport sector could be met from ethanol by the year 2030 under different scenarios. About US$200-400 million per annum could be saved along with other environmental and health benefits by using gasol in the transport sector. (author)

    This study analyze the potential factors influencing the growth of transport sector carbon dioxide (CO 2 ) emissions in selected Asian countries during the 1980-2005 period by decomposing annual emissions growth into components representing changes in fuel mix, modal shift, per capita gross domestic product (GDP) and population, as well as changes in emission coefficients and transportation energy intensity. We find that changes in per capita GDP, population growth and transportation energy intensity are the main factors driving transport sector CO 2 emission growth in the countries considered. While growth in per capita income and population are responsible for the increasing trend of transport sector CO 2 emissions in China, India, Indonesia, Republic of Korea, Malaysia, Pakistan, Sri Lanka and Thailand; the decline of transportation energy intensity is driving CO 2 emissions down in Mongolia. Per capita GDP, population and transportation energy intensity effects are all found responsible for transport sector CO 2 emissions growth in Bangladesh, the Philippines and Vietnam. The study also reviews existing government policies to limit CO 2 emissions growth, such as fiscal instruments, fuel economy standards and policies to encourage switching to less emission intensive fuels and transportation modes.

  15. Differences in regional emissions in China's transport sector: Determinants and reduction strategies

    International Nuclear Information System (INIS)

    Xu, Bin; Lin, Boqiang

    2016-01-01

    With recent surge in the number of vehicles, particularly private vehicles, the transport sector has significantly contributed to the increase in energy consumption and carbon dioxide emissions in China. Most of the existing researches utilized time series data to investigate the factors influencing transport sector's carbon dioxide emission at the national level while neglecting the level of regional differences. This paper adopts provincial panel data from 2000 to 2012 and panel data models to examine the key driving forces of carbon dioxide emissions in the transport sector at the regional level in China. The estimation results show that the impacts of urbanization on carbon dioxide emissions in the transport sector vary across regions and decline continuously from the western region to the eastern and central regions. Private vehicles are more important than cargo turnover in emission reduction because of its relatively inefficient and excessive growth. The role of energy efficiency improvement in mitigating carbon dioxide emissions in the three regions varies due to significant differences in research and development investment and management efficiency. Hence, in order to effectively achieve emission reduction, local governments should consider all these factors as well as regional heterogeneity in developing appropriate mitigation policies. - Highlights: • The factors of carbon dioxide emissions in China's transport sector were explored. • The impact of urbanization on carbon dioxide emissions varies across regions. • Private vehicles are more critical than cargo turnover in emission reduction. • The role of energy efficiency in the three regions is exactly the opposite.

    This report aims at identifying measures to be implemented during coming years in order energy consumption of the transport sector to become consistent with energy scenarios, and at studying how these measures could be funded. After a presentation of the situation of the transport sector in terms of energy consumption (energy consumption by the different sub-sectors, greenhouse effect, relationship with mobility, issue of infrastructures and related investments) and of its objectives, this study proposes an overview of the content of various scenarios (NegaWatt, Ademe, Ministry of Ecology, Greenpeace). It proposes a brief overview and discussion of energy saving potentials and sources, and presents issues related to energy efficiency in the transport sector. It develops an action plan aimed at exploiting energy efficiency sources in transports. This action plan notably comprises: a political signal for a more efficient mobility, a support to change in mobility, actions in town planning to ease energy efficiency in transports, a more efficient use of the rolling stock, infrastructures for a more efficient transport sector, a price signal in favour of a more efficient transport. The next parts of the study discuss expenses of the transport sector, incomes and funding tools for energy efficiency in transports, financial needs for efficiency improvement, financial resources, and propose a road map

    2017-12-01

    India is one of the fastest growing major economies of the world. It imports three quarters of its oil demand, making transport sector major contributor of greenhouse gas (GHG) emissions. 40% of oil consumption in India comes from transport sector and over 90% of energy demand is from road transport sector. This has led to serious increase in CO2 emission and concentration of air pollutants in India. According to Intergovernmental Panel on Climate Change (IPCC), transport can play a crucial role for mitigation of global greenhouse gas emissions. Therefore, assessment of appropriate mitigation policies is required for emission reduction and cost benefit potential. The present study aims to estimate CO2, SO2, PM and NOx emissions from the road transport sector for the base year (2014) and target year (2030) by applying bottom up emission inventory model. Effectiveness of different mitigation strategies like inclusion of natural gas as alternate fuel, penetration of electric vehicle as alternate vehicle, improvement of fuel efficiency and increase share of public transport is evaluated for the target year. Emission reduction achieved from each mitigation strategies in the target year (2030) is compared with the business as usual scenario for the same year. To obtain cost benefit analysis, marginal abatement cost for each mitigation strategy is estimated. The study evaluates mitigation strategies not only on the basis of emission reduction potential but also on their cost saving potential.

  2. Change of direction required. Climate protection in the transport sector. Special report

    International Nuclear Information System (INIS)

    2017-11-01

    The transport sector is currently responsible for about one-fifth of Germany's greenhouse gas emissions. While in other sectors since 1990 partly clear emission reductions have been achieved, are the emissions of traffic during the same period even slightly increased. In his special report the German Council of Environmental Advisors (SRU) points out which strategic course should be set for the change in transport policy. The decarbonisation of the transport sector requires a consistent overall concept. It should be done as soon as possible, a switch to alternative drives. In traffic electromobility is to be accelerated, because of direct electrification the primary energy consumption is kept as low as possible. The extraction and recycling of the raw materials required for electromobility should be made sustainable. In addition, the energy consumption of motorized transport must also be be significantly further reduced, especially by on-board efficiency measures. In addition to technological changes a fundamental change of transport systems and mobility patterns is also necessary. The avoidance and relocation of traffic not only contributes to climate protection, but also to reduce its other environmental and health burdens. In order to promote cost transparency in the transport sector, taxes, levies and subsidies should be consistently aligned with climate, environmental and health policy objectives. For the SRU, this also includes the introduction of a route-dependent car toll. [de

    The objective of the report is to compare the emissions of greenhouse gases for alternative end-use technologies in the transportation sector. Scientists assert that global warming is occurring and will continue to occur as a result of increasing concentrations of certain gases in the atmosphere. Carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O) are the focus of this analysis because they are believed to cause three-fourths of the global warming effect and because energy production and use are a significant source of these emissions. Greenhouse gas emissions in the energy sector occur during energy production, conversion, transportation and end-use. This analysis compares alternative transportation sector fuel/technology choices in terms of their total fuel-cycle emissions of greenhouse gases. The emphasis of this report is on the end use comparison. The fuel-cycle emissions comparison was developed in a companion report

  7. The crisis of gasoline consumption in the Iran's transportation sector

    2008-01-01

    Fossil fuels have the greatest share in supplying the world's energy demands. Regarding the limited natural resources, fuel consumption management and energy planning in the end-user sectors are two great matters of importance. Among the fossil fuels, gasoline is the principal fuel for light-duty vehicles. In Iran, fuel consumption, especially that of gasoline, has increased sharply with the growth rate of 10.2% for the year 2006 in comparison with that in 2005, turning into a big crisis in the recent years. On the other hand, enormous subsidies for importing 40% of domestic demands, which have reached more than 10 billion US$, are too much to be supplied. In this study, we have assessed the gasoline consumption, production, import and prices; reviewed main causes of the tremendous growth rate of consumption, current conservation policies and their advantages or disadvantages (SWOT analysis); proposed short- to long-term solutions and strategies for efficient gasoline consumption management; and finally, current strategies and proposed solutions are analyzed and evaluated. A foregone conclusion strongly suggests that not only the low price of motor gasoline but also mass production of vehicles with the conventional technology, likewise, affects motor gasoline demand. A second conclusion is that gasoline crisis in Iran has no straight solution, and that fundamental strategies and policies are needed to solve the problem. (author)

    Recent analyses suggest that especially biogas, but also natural gas in macroeconomic terms will be attractive propellants, including for heavy transport. To implement a Danish expansion of gas infrastructure for transportation, the report recommends the following essential elements: 1) A Danish rollout should be closely linked to contracts with fleet owners with heavy vehicles / taxis / vans and the like, thus ensuring high utilization of filling stations; 2) About 10 larger, flexible CNG filling stations set up at major fleet owners is estimated as sufficient for an initial deployment phase, strategically distributed in and around Copenhagen, the major cities and along the main road network from Sweden to Germany; 3) A certain time-limited funding for the construction of infrastructure is likely to cause a rapid spread, if desired, and if other business conditions are in place; 4) There is a need for adjustment of tax terms - the rules for green taxes should be adjusted, and it should be considered to lower the taxes on CNG and biogas; 5) Natural gas mixed with biogas should be an integral element of a comprehensive strategy to ensure maximum CO{sub 2} displacement.

    2009-01-01

    Rapid growth of road vehicles, private vehicles in particular, has resulted in continuing growth in China's oil demand and imports, which has been widely accepted as a major factor effecting future oil availability and prices, and a major contributor to China's GHG emission increase. This paper is intended to analyze the future trends of energy demand and GHG emissions in China's road transport sector and to assess the effectiveness of possible reduction measures. A detailed model has been developed to derive a reliable historical trend of energy demand and GHG emissions in China's road transport sector between 2000 and 2005 and to project future trends. Two scenarios have been designed to describe the future strategies relating to the development of China's road transport sector. The 'Business as Usual' scenario is used as a baseline reference scenario, in which the government is assumed to do nothing to influence the long-term trends of road transport energy demand. The 'Best Case' scenario is considered to be the most optimized case where a series of available reduction measures such as private vehicle control, fuel economy regulation, promoting diesel and gas vehicles, fuel tax and biofuel promotion, are assumed to be implemented. Energy demand and GHG emissions in China's road transport sector up to 2030 are estimated in these two scenarios. The total reduction potentials in the 'Best Case' scenario and the relative reduction potentials of each measure have been estimated

    Energy use in the European Union's (EU) transport sector amounted to 340 Mtoe in 1999 with the following increasing trend up to 379 Mtoe in 2007 and a decrease from 2008 on, down to 365 Mtoe in 2010. This changing pattern posed several fundamental questions and uncertainties regarding the broader picture of energy efficiency and environmental protection. One of them refers to absolute changes in energy use efficiency in the transport sector over time and the ways of measuring efficiency. Traditional scientific approaches conceptualized to measure efficiency of energy use do not address annual dynamics of changes in the energy use in a given sector per capita. Thus, they are not precise enough for political and methodological purposes as they do not reflect the exact amount of energy consumed in the respective countries and societies. This paper shows a possible solution to this problem and a new perspective on measuring energy efficiency by using the product generational dematerialization (PGD) indicator. The PGD indicator allows for measuring energy efficiency as a dynamic change of consumption and population occurring simultaneously. Thus, it provides an extension to the traditional methodology commonly used for measuring efficiency. To visualize a practical application of this approach, the paper provides an example of evaluating energy efficiency in the transport sector in the EU-27 in 2000–2010. The results of the analysis show a clear materialization tendency in the transport sector (the energy consumption change exceeded the population growth) until 2007 and a reverse tendency (dematerialization) between 2008 and 2010. As energy consumption has a direct impact on environmental quality and exhaustion of natural resources, the paper points out the necessity of extending sustainable resource management policies by new methodologies and providing more efficient solutions for energy consumption in the transport sector. - Highlights: • PGD indicator proves a

    Highlights: • The activity effect accounts for 98.05% increase in energy use. • Only Eastern’s structural effect contributes energy savings. • Intensity effect contributes energy saving in −4.24% of total energy changes. • Energy-mix effect is insignificant. - Abstract: As one of the three high-energy consumption sectors (industry, building, and transportation) in China, the transport sector faced a devastating resource and environment challenge. The transport sector was reportedly responsible for about 15.9% of the country’s total final energy consumption in 2008. This paper investigates the energy consumption and efficiency of China’s transport sector from 2003 to 2009. The transport energy data of 30 China administrative regions were divided into “three-belts” (Eastern, Western, and Central areas), and the corresponding turnovers were reported and analyzed using an index decomposition analysis (Logarithmic Mean Divisia Index). The energy data and turnover of the transport sector indicated that the high growth rate of turnover results is attributed to the high growth rate of diesel, assuming that diesel is the major fuel for freight transport. The growth of diesel is the main contributor to the overall growth of energy consumption. The growth rate of gasoline has become minimal since 2006. Since 2005, all three-belt areas, with regard to the effectiveness of energy conservation policies, have continuously improved their energy efficiencies based on the results of decomposition analysis. The energy intensity effect shows that the energy conservation and efficiency policies were more effective in the Central and Western areas than that in the Eastern area. On the other hand, the regional shift effect indicates that the policies favor to the Eastern area since only its regional shift effect contributes energy savings since 2008. The energy-mix effect is insignificant, which indicates that it is not necessary to conduct CO 2 emission decomposition

    Rapid growth of population and economy during the past two decades has resulted in continuing growth of transport’s oil demand and greenhouse gas (GHG) emissions. The objectives of this study are to examine pattern and growth in energy demand as well as related GHG emissions from the transport sector and to analyze potential pathways of energy demand and GHG emissions reduction from this sector of the measures being set by the Thai Government. A set of econometric models has been developed to estimate the historical trend of energy demand and GHG emissions in the transport sector during 1989–2007 and to forecast future trends to 2030. Two mitigation option scenarios of fuel switching and energy efficiency options have been designed to analyze pathways of energy consumption and GHG emissions reduction potential in Thailand’s transport sector compared with the baseline business-as-usual (BAU) scenario, which assumed to do nothing influences the long-term trends of transport energy demand. It has been found that these two mitigation options can reduce the GHG emissions differently. The fuel-switching option could significantly reduce the amount of GHG emissions in a relatively short time frame, albeit it will be limited by its supply resources, whereas the energy efficiency option is more effective for GHG emissions mitigation in the long term. Therefore, both measures should be implemented simultaneously for both short and long term mitigation effects in order to more effectively achieve GHG emissions reduction target.

    Highlights: • The overall energy and exergy efficiencies of the sector were calculated. • The overall efficiencies were compared to other countries. • The overall energy and exergy efficiencies have been predicted by scenario approach. • A summary of recommendations to improve the sector is provided. - Abstract: Transportation is the second largest energy consumer sector in Iran which accounts for 24% of total energy consumption in 2009. This large percentage (almost a quarter) of energy consumption necessitates the determination of energy and exergy flows and their respective losses, which will enable the reduction of both energy growth and its consequent environmental impacts in the near future. This paper attempts to analyze and investigate the energy and exergy utilization of the transportation sector in Iran for the period of 1998–2009. Additionally, the total energy consumption in each subsector and the overall energy and exergy efficiencies are predicted via scenario approach. A comparison of the overall energy and exergy efficiencies of Iran with six other countries is also presented. The results show that the overall energy and exergy efficiencies of transportation sector in Iran is higher than China and Norway, while it is lower than Saudi Arabia, Jordan, Turkey, and Malaysia for the year 2000. Road appears to be the most efficient subsector. The overall energy efficiency is determined to be in the range of 22.02% in 1998, to 21.49% in 2009, while the overall exergy efficiency is determine to be in the range of 21.47% in 1998, to 21.19% in 2009. The energy consumption in each subsector is predicted from 2010 to 2035. It was discovered that the overall energy and exergy efficiencies possesses an upward trend during this time period. Finally, some recommendations vis-à-vis the improvement of the energy and exergy efficiencies in Iranian transportation sector in the future was provided and duly discussed

    China is experiencing intensified industrialisation and motorisation. In the world's largest emerging economy, energy efficiency is expected to play a critical role in the ever-rising demand for energy. Based on factual overviews and numerical analysis, this article carries out an in-depth investigation into the effectiveness of policies announced or implemented in recent decades targeted at energy conservation in the energy intensive manufacturing and transportation sectors. It highlights nine energy intensive sectors that achieved major improvements in their energy technology efficiency efforts. Under the umbrella of the 11th Five-Year Plan, these sectors' performances reflect the effectiveness of China's energy conservation governance. Numerous actions have been taken in China to reduce the road transport sector's demand for energy and its GHG emissions by implementing fuel economy standards, promoting advanced energy efficient vehicles, and alternative fuels. Coal-based energy saving technologies, especially industrial furnace technologies, are critical for China's near and medium-term energy saving. In the long run, renewable energy development and expanding the railway transport system are the most effective ways to reduce energy use and GHG emissions in China.

    This study aims at examining energy and exergy efficiencies in Turkish transportation sector. Unlike the previous studies, historical data is used to investigate the development of efficiencies of 17 years period from 1988 to 2004. The energy consumption values in tons-of-oil equivalent for eight transport modes of four transportation subsectors of the Turkish transportation sector, including hard coal, lignite, oil, and electricity for railways, oil for seaways and airways, and oil and natural gas for highways, are used. The weighted mean energy and exergy efficiencies are calculated for each mode of transport by multiplying weighting factors with efficiency values of that mode. They are then summed up to calculate the weighted mean overall efficiencies for a particular year. Although the energy and exergy efficiencies in Turkish transport sector are slightly improved from 1988 to 2004, the historical pattern is cyclic. The energy efficieny is found to range from 22.16% (2002) to 22.62% (1998 and 2004) with a mean of 22.42±0.14% and exergy efficiency to range from 22.39% (2002) to 22.85% (1998 and 2004) with a mean of 22.65±0.15%. Overall energy and exergy efficiencies of the transport sector consist mostly of energy and exergy efficiencies of the highways subsector in percentages varying from 81.5% in 2004 to 91.7% in 2002. The rest of them are consisted of other subsectors such as railways, seaways, and airways. The overall efficiency patterns are basically controlled by the fuel consumption in airways in spite of this subsector's consisting only a small fraction of total. The major reasons for this are that airways efficiencies and the rate of change in fuel consumption in airways are greater than those of the others. This study shows that airway transportation should be increased to improve the energy and exergy efficiencies of the Turkish transport sectors. However, it should also be noted that no innovations and other advances in transport technologies are

  4. Energy and the transport sector. [For countries with no fossil fuels

    This article describes the current energy situation from both the global viewpoint and the viewpoint of countries with no indigenous sources of fossil fuels. The lack of fossil fuels necessitates a substitution with indigenous sources of energy, where feasible. Long-distance railway transport is a self-evident element in the expanding transport sector. In view of the proven high energy efficiency of electric railway systems, there is every incentive for a more active investment policy in railway electrification. This applies to both medium-distance transportation of freight and passengers and different electric mass transit systems.

    The transportation sector is responsible for 37% of the total final energy consumption in Jordan, with passenger cars taking a share of 57% in this sector. Improvement of the energy efficiency of the transportation sector can help in alleviating socio-economic pressures resulting from the inflating fuel bill and in lowering the relatively high CO 2 emission intensity. Current legislations mandate that all passenger cars operating in Jordan are to be powered with spark ignition engines using gasoline fuel. This paper examines potential benefits that can be achieved through the introduction of diesel cars to the passenger cars market in Jordan. Three scenarios are suggested for implementation and investigated with a forecasting model on the basis of local and global trends over the period 2007-2027. It is demonstrated that introducing diesel passenger cars can slow down the growth of energy consumption in the transportation sector resulting in significant savings in the national fuel bill. It is also shown that this is an effective and feasible option for cutting down CO 2 emissions

    Full Text Available It is important to evaluate the impact of economic fluctuations on the transport sector operational efficiency, since such an analysis is a source of economic information which contributes to the identification of the sector's potential and advantages, the establishment of the risky areas of activity, and the exploration of the opportunities to increase its effectiveness. The aim of the study was to apply mathematical evaluation methods to the exploration of the operational efficiency of the Lithuanian transport sector companies and, based on the outcomes, to validate the opportunity of predicting a potential change of the economic cycle. The operational efficiency of the Lithuanian transport sector was analysed in the context of the cyclical national economy, and not in individual economic boom or recession periods, as that allowed for more detailed evaluation of the specific activities of the sector and its impact on Lithuanian economy. To achieve the aim, three different stages of the economic cycle in Lithuania were identified, and calculations were made during them. Based on the aggregate financial data, four different economic efficiency indicators were developed that reflected the efficiency level of the entire transport sector, and the sensitivity of the transport sector to economic fluctuations was identified. The comparison of the changes in the transport sector and in Lithuanian economy made it obvious that the level of the sector's operational efficiency could be regarded as a leading indicator of the economic cycle.

    The road transport sector is the largest consumer of commercial fuel energy within the transportation system in India and accounts for nearly 35% of the total liquid commercial fuel consumption by all sectors. Gasoline and diesel consumption for road transportation have quadrupled between 1980 and 2000 due to about nine times increase in the number of vehicles and four-fold increase in freight and passenger travel demands. The paper elaborates the trends of energy consumption and consequent emissions of greenhouse gases such as CO 2 , CH 4 and N 2 O and ozone precursor gases like CO, NO x and NMVOC in the road transport sector in India for the period from 1980 to 2000. For the first time, efforts have been made to apportion the fuels, both diesel and gasoline, across different categories of vehicles operating on the Indian roads. In order to generate more comprehensive and complete emission estimates, additionally, other minor fuel types like light diesel oil and fuel oil along with lubricants have also been taken into account. Emission estimates have revealed that nearly 27 Mt of CO 2 were emitted in 1980, increasing to about 105 Mt in 2000. Similar trends have also been observed for other gases. Further scope for improvements in emission estimation is possible by generating country specific emission factors for different vehicle categories and improvement in documentation of fuel consumption at segregated levels by fuel types and vehicle types

    Full Text Available Transportation Build-Operate-Transfer financing projects have larger payment risks and failure possibilities than other financing projects, and these factors are essential to financing scenarios. The changes of financing scenarios not only affect private sectors' financing process but the conflict between private sectors and banks. This study broadly reviews relevant factors affecting BOT financing strategies, interviews relevant experts and then uses scenario analysis to design a questionnaire to find out the most important factors affecting BOT financing. The findings of this study are four major factors affecting public and private financing scenarios. In this paper, we also propose some suggestions as possible complements to public and private sector financing strategies.

    With rapid economic growth, the transport sector plays an important role in China′s CO 2 emissions. The existing research is extensively concerned with transport sector CO 2 emissions in recent years, but little attention has been paid to regional differences. This paper investigates CO 2 emissions in the transport sector at the national and regional levels using the STIRPAT model and provincial panel data from 1995 to 2010 in China. The results showed that passenger transport dominates CO 2 emissions in the transport sector, but its influence varies across regions. Electrification has significant potential to lower CO 2 emissions because of resulting higher fuel efficiency and reduced pollution. Energy efficiency improvement is effective but limited in reducing emissions due to increasing demand from economic development and population growth. These results not only contribute to advancing the existing literature, but also merit particular attention from policy makers in China. - Highlights: • We investigate China′s CO 2 emissions in the transport sector. • Passenger transport dominates CO 2 emissions in the transport sector. • The effects of passenger transport on CO 2 emissions vary across regions. • Energy efficiency improvement is effective but limited in reducing emissions

    Use of both natural gas and renewable energy has grown significantly in recent years. Both forms of energy have been touted as key elements of a transition to a cleaner and more secure energy future, but much of the current discourse considers each in isolation or concentrates on the competitive impacts of one on the other. This paper attempts, instead, to explore potential synergies of natural gas and renewable energy in the U.S. electric power and transportation sectors.

    The CNG program in Argentina was formulated in the early 80's with the goal of reaching energy independence by means of a greater participation of natural gas in the energy demand. The transport sector is responsible of 30% of the total energy demand and 60% of all the oil consumption, so that any plan for substituting liquid fuels had to tackle transportation. The experiences which allowed gas to increase its participation from 27% to 33% may be profited by others interested in producing similar projects. (author)

    1996-08-01

    Several studies have established that Trinidad and Tobago is well positioned to consider the substitution of compressed natural gas (CNG) for gasoline or diesel in the transport sector. Consequently a programme of conversion of private motors was initiated. Despite considerable advertisement programs projecting CNG as an environmentally friendly and cheap fuel, there is not yet widespread acceptance of the technology. The reasons for this are analysed. It is recommended that the policy of CNG usage be reviewed and the emphasis be shifted to transport fleets. It is also recommended that tax credits be considered as an incentive to users. (author)

    Transportation sectors in developing countries suffer from some diseases that one of them is ever-increasing energy consumption. Integrated National Energy Planning (INEP) in transportation sector is a solution for these countries to alter their suboptimal pattern and rationalize their energy consumption. One of the INEP targets is determining optimal patterns of fuels and transportation technologies to satisfy future demand of freight and passenger transportation at the lowest cost levels. Following the above target, this paper is concerned with the optimal consumption pattern of fuels focusing on vehicle technologies within the next 25 years (up to 2029). Using Energy Flow Optimization Model-ENVironment (EFOM-ENV) model, various steps as designing of ''Reference Energy System (RES)'' of the model, data processing and scenario analysis are followed. Based on the modeling results, substitution of urban railroad technologies (subway, LRT and monorail), all of passenger CNG technologies (cars, buses and minibuses), rural railroad freight technologies (electrical, gas oil and LNG freight trains) and finally, CNG and LNG heavy and light trucks with current passenger and freight vehicle technologies are suggested. This scenario will decline fuel consumption by about 14% totally, that the most part of it belongs to gasoline and gas oil (24% and 17%, respectively). Total discounted cost of transportation system will decline from 806.20 to 691.74 billion dollars (14%) during the time horizon. (author)

    Full Text Available Since 2009, shortly after the global economic crisis of 2008, Greece has entered into a deep recession phase. The multifaceted presence of austerity is experienced in an increasing number of sectors of the country. The Greek transportation sector is not immune to this state of affairs. The ongoing crisis had a significant impact on its economic (investment, employment, exports-imports turnover as well as its operational (transportation intensity, throughput, performance aspects and capabilities. In this paper, a detailed mapping of these impacts is laid out, correlating transport-related characteristics, trends and estimations with the respective economic ones. Specifically, the paper presents analyses of the Greek passenger and freight transportation, following a data-driven approach over several areas. Findings show a substantial decrease of activities overall. Paradoxically, however, austerity can also be said to offer opportunities, such as the development of innovative, cost-effective and outward-looking business schemes, for handling transportation-related issues. In the face of these opportunities, authorities and stakeholders have recently turned their attention to ways of harnessing them as they may arise. The paper conducts a detailed analysis of these efforts to discover prospects for development in the midst of austerity, and highlights the steps currently being taken in that direction.

    This paper evaluates alternative fuels for the Greek road transport sector, using the Analytic Hierarchy Process. Seven different alternatives of fuel mode are considered in this paper: internal combustion engine (ICE) and its combination with petroleum and 1st and 2nd generation biofuels blends, fuel cells, hybrid vehicles, plug-in hybrids and electric vehicles. The evaluation of alternative fuel modes is performed according to cost and policy aspects. In order to evaluate each alternative fuel, one base scenario and ten alternative scenarios with different weight factors selection per criterion are presented. After deciding the alternative fuels’ scoring against each criterion and the criteria weights, their synthesis gives the overall score and ranking for all ten alternative scenarios. It is concluded that ICE blended with 1st and 2nd generation biofuels are the most suitable alternative fuels for the Greek road transport sector. - Highlights: ► Alternative fuels for the Greek road transport sector have been evaluated. ► The method of the AHP was used. ► Seven different alternatives of fuel mode are considered. ► The evaluation is performed according to cost and policy aspects. ► The ICE with 1st and 2nd generation biofuels are the most suitable fuels.

    Full Text Available We use the EMAC (ECHAM/MESSy Atmospheric Chemistry global model with the aerosol module MADE (Modal Aerosol Dynamics model for Europe, adapted for global applications to quantify the impact of transport emissions (land transport, shipping and aviation on the global aerosol. We consider a present-day (2000 scenario according to the CMIP5 (Climate Model Intercomparison Project Phase 5 emission data set developed in support of the IPCC (Intergovernmental Panel on Climate Change Fifth Assessment Report. The model takes into account particle mass and number emissions: The latter are derived from mass emissions under different assumptions on the size distribution of particles emitted by the three transport sectors. Additional sensitivity experiments are performed to quantify the effects of the uncertainties behind such assumptions. The model simulations show that the impact of the transport sectors closely matches the emission patterns. Land transport is the most important source of black carbon (BC pollution in the USA, Europe and the Arabian Peninsula, contributing up to 60–70% of the total surface-level BC concentration in these regions. Shipping contributes about 40–60% of the total aerosol sulfate surface-level concentration along the most-traveled routes of the northern Atlantic and northern Pacific oceans, with a significant impact (~ 10–20% along the coastlines. Aviation mostly affects aerosol number, contributing about 30–40% of the particle number concentration in the northern midlatitudes' upper troposphere (7–12 km, although significant effects are also simulated at the ground, due to the emissions from landing and take-off cycles. The transport-induced perturbations to the particle number concentrations are very sensitive to the assumptions on the size distribution of emitted particles, with the largest uncertainties (about one order of magnitude obtained for the land transport sector.

    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.

    2015-01-01

    Full Text Available Using the EMAC (ECHAM/MESSy Atmospheric Chemistry global climate-chemistry model coupled to the aerosol module MADE (Modal Aerosol Dynamics model for Europe, adapted for global applications, we simulate the impact of land transport and shipping emissions on global atmospheric aerosol and climate in 2030. Future emissions of short-lived gas and aerosol species follow the four Representative Concentration Pathways (RCPs designed in support of the Fifth Assessment Report of the Intergovernmental Panel on Climate Change. We compare the resulting 2030 land-transport- and shipping-induced aerosol concentrations to the ones obtained for the year 2000 in a previous study with the same model configuration. The simulations suggest that black carbon and aerosol nitrate are the most relevant pollutants from land transport in 2000 and 2030 and their impacts are characterized by very strong regional variations during this time period. Europe and North America experience a decrease in the land-transport-induced particle pollution, although in these regions this sector remains a major source of surface-level pollution in 2030 under all RCPs. In Southeast Asia, however, a significant increase is simulated, but in this region the surface-level pollution is still controlled by other sources than land transport. Shipping-induced air pollution is mostly due to aerosol sulfate and nitrate, which show opposite trends towards 2030. Sulfate is strongly reduced as a consequence of sulfur reduction policies in ship fuels in force since 2010, while nitrate tends to increase due to the excess of ammonia following the reduction in ammonium sulfate. The aerosol-induced climate impact of both sectors is dominated by aerosol-cloud effects and is projected to decrease between 2000 and 2030, nevertheless still contributing a significant radiative forcing to Earth's radiation budget.

    1978-12-01

    Forecasts of U.K. energy consumption in this sector for four future scenarios based on different economic growth rates, energy prices, and energy conservation policies, show that by the year 2000, private transport will probably account for 76-94% of total energy consumption in surface passenger transport. A 33% increase in the average miles-per-gallon fuel consumption through technological improvements in private vehicles, conversion of private vehicles to diesel oil, additional fuel taxation equivalent to 25 or 50% fuel price increase, a 10% reduction in average car engine size (encouraged by taxation), and changes in public transport technology offer energy savings of about 20, 5-10, 6.3 or 12.5, 2-4, and 2%, respectively. There is considerable uncertainty about the outcome of these options.

    Transportation sector of Canada is the second largest energy consuming sector which accounts for 30% of the total energy consumption of the country in 2009. The purpose of this work was to analyze the energy, exergy, and emission performance for four different modes of transport (road, air, rail, and marine) from the year 1990–2035. For historical period, the estimated overall energy efficiency ranges from 22.41% (1991) to 22.55% (2006) with a mean of 22.48 ± 0.07% and the overall exergy efficiency ranges from 21.61% (2001) to 21.87 (2006) with a mean of 21.74 ± 0.13%. Energy and exergy efficiencies may reach 20.95% and 20.97% in the year 2035 respectively based on the forecasted data. In comparison with other countries, we found that in the year 2000 the overall energy and exergy efficiencies for Canadian transportation sector were higher than Jordan, China, Norway, and Saudi Arabia but lower than Turkey and Malaysia. Between the year 1990–2009, the highest amount of emission produced in each subsector was: road CO 2 (80%), NO x (72%), and CO (carbon monoxide) (96%); air SO 2 (86%); rail NO x (6%) and marine NO x (7%). The road subsector produced the highest amount of emissions. - Highlights: • Energy, exergy and emission performance for Canadian transport was analyzed. • Maximum energy and exergy efficiencies were 22.55% and 21.87% in 2006 respectively. • Energy and exergy efficiencies may decrease in the year 2035. • CO 2 was the largest pollutant emitted followed by CO, NO x , and SO 2 . • Utilization of green fuels can improve exergy and emission performance

    We use a newly developed bottom-up model of the entire Canadian energy system (TIMES-Canada) to assess potentials for electrification of the road transport sector. A special emphasis has been put on the modelling of the Canadian road transport, by considering a variety of vehicles for passenger and freight transportation. Besides a business-as-usual (baseline) scenario, we have analysed an energy policy scenario imposing targets for electric vehicle penetration and a climate policy scenario imposing targets for greenhouse gas emission reduction. Our analysis shows on the one hand that electric vehicles penetrate notably the passenger vehicle market after 2040 in the baseline scenario and after 2030 in the energy policy scenario (following the assumed penetration targets). On the other hand, the assumed climate policy forces a stronger penetration of electric vehicles for passenger transportation, with a progressive phasing out of internal combustion engine vehicles, whereas the latter vehicles remain dominant for freight transportation but with a shift away of fossil fuels and in favour of biofuels. A sensitivity analysis on the (assumed) evolution of electric vehicles over time confirms these general trends. -- Highlights: •We use a newly developed TIMES-Canada model of the entire Canadian energy system. •We assess potentials for electrification of the Canadian road transport sector. •We analyse three scenarios: baseline, energy policy and climate policy. •EVs penetrate notably after 2040 in the baseline and after 2030 in the energy policy scenario. •The climate policy forces a stronger penetration of EVs

    2017-01-01

    This paper presents a two pronged approach to the study of the rebound effect, with the aim of assessing the magnitude of the effect in the European freight transport sector and proposing a new modelling framework based on network theory. The (direct) rebound effect is assessed with: 1) an econometric regression; 2) a model based on network theory and statistical mechanics. According to the econometric model the European road freight transport sector undergone a negative rebound between of −74% between 1998 and 2007 and −146% between 1998 and 2011. The network analysis delivers an estimation of network rebound ranging between −29.37% and −7.25. Overall, these results indicate that energy efficiency in Europe, between 1998 and 2011, succeed in reducing the energy consumptions amid an increasing demand for transports. Results on rebound estimation depend on the decision of using GDP as an exogenous variable, an assumption that leaves questions open about the causality chain between growth and transports. Furthermore, the network analysis highlights a structural change –a migration of production factors offshore, that might partially explain this negative effect. In this view, rebound effect analysis on a local or regional scale is becoming more and more uncertain in a globally interconnected economic context. - Highlights: • An evaluation of direct rebound effect in the freight transports with an econometric model is performed. • A new concept of rebound effect based on network theory is presented and implemented. • A comparative analysis of the two different approaches is developed. • Both models indicate that the there was a negative rebound effect in European freight transports. • Network theory proved to be a promising approach to energy systems and rebound effect modelling.

    The objective of this paper is to identify the most valuable sector for the use of bioenergy in a flexible energy system in order to meet the energy policy objectives of Inland Norway. A reference system was used to construct alternative systems in the heating and transport sectors. The alternative system in the heating sector is based on heat pumps and bio-heat boilers while the alternative systems in the transport sector are based on three different pathways: bio-dimethyl ether, hydrogen fuel cell vehicles and battery electric vehicles. The alternative systems were compared with the reference system after a business-economic optimisation had been made using an energy system analysis tool. The results show that the excess electricity availability due to increased energy efficiency measures hampers the competitiveness and penetration of bio-heating over heat pumps in the heating sector. Indeed, the synergy effect of using bio-dimethyl ether in the transport sector for an increased share of renewable energy sources is much higher than that of the hydrogen fuel cell vehicle and battery electric vehicle pathways. The study also revealed that increasing renewable energy production would increase the renewable energy share more than what would be achieved by an increase in energy efficiency. -- Highlights: •Bio-heating is less competitive over heat pump for low quality heat production. •Renewable energy production meets policy objectives better than system efficiency. •Bioenergy is more valuable in the transport sector than the heating sector

    The need for small and medium enterprises (SMEs) to adopt data analytics has reached a critical point, given the surge of data implied by the advancement of technology. Despite data mining (DM) being widely used in the transportation sector, it is staggering to note that there are minimal research case studies being done on the application of DM by SMEs, specifically in the transportation sector. From the extensive review conducted, the three most common DM models used by large enterprises in...

    The Mexican transportation sector, as with that of many other countries, is characterized by basing its energy consumption in hydrocarbons (gasoline, diesel and LP gas). At the present times, this dependency has brought along a series of problems of environmental nature, which concentrate in a larger scale in the urban areas. Therefore, the study of the transportation sector as an energy consumer requires the institution of new terms where the constant to study (directly or indirectly) is the environmental variable, trying to correlate the proper sector activities, its development and the energy consumption with the environment. This paper`s objective is to know the actual situation of the transportation sector in the metropolitan area of Mexico City (MAMC) and its environmental impact. It is therefore an energy-environmental inventory energy-environmental focussed to the use of fuels in the transportation sector, whose environmental effect has a significant cost for the country. This paper has been divided in four parts. First, the importance of the sector as an energy consumer in the MAMC is characterized in aggregated form. Second, the main variables that affect the development of the sector to obtain the consumption in separated form as well as the base criteria for its development, obtaining a series of results that show the effect of the different modes and types of energy consumption. In the third part, reference is made to the environmental impact originated by the utilization of fossil fuels in the transportation sector, emphasizing in the transportation means that more heavily affect for the emission of pollutants. Finally a series of options are presented that allow finding an equilibrium among transportation, energy and environment.

    2010-10-01

    A comprehensive review of the current situation of energy resources and consumption and of the prevailing framework like climate change is given, with a focus on Switzerland. The author, a member of the Lower House of the Swiss Parliament, presents facts and figures in a simple language, illustrated by tables and diagrams, in a well structured, easy-to-read book, with detailed indications of his data sources. Starting from the limited character of fossil energy sources, 'peak-oil' and the necessary reduction of greenhouse gas emissions, the author states that nuclear energy is not the solution. Action is absolutely needed, but which policy should be adopted? A global strategy is required that includes the stabilization of the world population as a key factor. An international agreement signed by as many states as possible should create stringent commitments. The developed countries have to demonstrate that prosperity and high life standard are compatible with an economy based on renewable energy sources. This will give to the most ambitious countries a significant advantage on new markets created by renewable energy use and energy efficiency. The author goes on by describing the current status of the technologies needed. What regards the particular case of Switzerland, this country is strongly dependent on energy import - mainly fossil - and CO 2 emissions arise mainly from the building and transportation sectors. A 50% efficiency improvement until 2030 is needed in fossil energy use. Electricity use has to become more efficient as well. Electricity generation - today about 60% renewable - shall move towards 100% renewable. The next chapters discuss clear realistic proposals on how to achieve these goals in the transportation sector ('Intelligent mobility'), the building sector ('Retrofitting the buildings to get them up-to-date') and the electrical power sector ('Entirely renewable electricity'). The title of the conclusion chapter: 'Focus again on the general

    Use of biofuels as transport fuel has high prospect in developing countries as most of them are facing severe energy insecurity and have strong agricultural sector to support production of biofuels from energy crops. Rapid urbanization and economic growth of developing countries have spurred air pollution especially in road transport sector. The increasing demand of petroleum based fuels and their combustion in internal combustion (IC) engines have adverse effect on air quality, human health and global warming. Air pollution causes respiratory problems, adverse effects on pulmonary function, leading to increased sickness absenteeism and induces high health care service costs, premature birth and even mortality. Production of biofuels promises substantial improvement in air quality through reducing emission from biofuel operated automotives. Some of the developing countries have started biofuel production and utilization as transport fuel in local market. This paper critically reviews the facts and prospects of biofuel production and utilization in developing countries to reduce environmental pollution and petro dependency. Expansion of biofuel industries in developing countries can create more jobs and increase productivity by non-crop marginal lands and wastelands for energy crops plantation. Contribution of India and China in biofuel industry in production and utilization can dramatically change worldwide biofuel market and leap forward in carbon cut as their automotive market is rapidly increasing with a souring proportional rise of GHG emissions.

    Transportation of food products at controlled temperature is a critical task in the transport sector. In fact, whilst there is a need of ensuring both food quality and safety to the global population, its impact in terms of energy consumption and related CO2 emissions into the atmosphere is becoming increasingly evident. In this regard, Thermal Energy Storage (TES) using Phase Change Materials (PCMs) can be considered as a potential way of reducing the cooling load, energy consumption and related greenhouse gas emissions in refrigerated transport sector. In this paper two different PCM applications are investigated. Specifically, in the first study a PCM (35 °C melting temperature) layer was added to the external side of a refrigerated enclosure wall with the aim of managing the cooling peak (shifting and reducing) and reducing the daily energy rate. Outdoor experimental results showed that the added PCM layer helps to reduce (between 5.55% and 8.57%) and delay (between 4.30 h and 3.30 h) the peak load of incoming heat compared to the reference one. In the second study, the energy performance of a refrigerated chamber with an air heat exchanger containing PCM (5°C melting temperature) was investigated. The study purpose was to reduce the cooling energy consumption during steady state operating conditions and the rate of temperature increase throughout the course of a power failure event. Test results showed that using a PCM air heat exchanger addition, up to 16% of energy can be saved.

    Full Text Available “Linking the power and transport sectors—Part 1” describes the general principle of “sector coupling” (SC, develops a working definition intended of the concept to be of utility to the international scientific community, contains a literature review that provides an overview of relevant scientific papers on this topic and conducts a rudimentary analysis of the linking of the power and transport sectors on a worldwide, EU and German level. The aim of this follow-on paper is to outline an approach to the modelling of SC. Therefore, a study of Germany as a case study was conducted. This study assumes a high share of renewable energy sources (RES contributing to the grid and significant proportion of fuel cell vehicles (FCVs in the year 2050, along with a dedicated hydrogen pipeline grid to meet hydrogen demand. To construct a model of this nature, the model environment “METIS” (models for energy transformation and integration systems we developed will be described in more detail in this paper. Within this framework, a detailed model of the power and transport sector in Germany will be presented in this paper and the rationale behind its assumptions described. Furthermore, an intensive result analysis for the power surplus, utilization of electrolysis, hydrogen pipeline and economic considerations has been conducted to show the potential outcomes of modelling SC. It is hoped that this will serve as a basis for researchers to apply this framework in future to models and analysis with an international focus.

    The present work provides an international comparison of the energy intensity and the carbon dioxide intensity in road transport for a group of 90 countries over the period 1980–2012. This paper attempts to perform a comparative analysis to find the most appropriate mapping of the energy performance in road transport taking into account the three dimensions of sustainable energy development, namely road transport-related energy consumption, economic growth and carbon dioxide emissions. An important result of the study is the inverse relationship between energy efficiency and environmental efficiency. Through the calculated Theil coefficient, our empirical findings highlight the existence of spatial and temporal disparities between countries. In 2012, Tunisia occupies the 48th and the 38th rank respectively in terms of energy and environmental efficiency. Based on a general index of energy performance in the road transport sector, it is deemed to have a medium–high energy performance by occupying the 34th rank. The study shows the importance of enhancing a number of policies for the road transport system through the joint improvement of the fuel price policy, of the road infrastructure policy and of the fuel-efficient road vehicles policy, in order to maintain sustainable energy road transport. - Highlights: • The paper presents an international comparative analysis of the energy performance. • The road transport is analyzed for a group of 90 countries over the period 1980–2012. • There is no convergence between energy and environmental efficiencies. • Tunisia has a medium-high energy performance by occupying the 34th rank in 2012. • The findings show the importance of enhancing some policies for the road transport.

    The purpose of this work is to apply the useful energy and exergy analysis models for different modes of transport in Malaysia and to compare the result with a few countries. In this paper, energy and exergy efficiencies of the various sub-sectors are presented by considering the energy and exergy flows from 1995 to 2003. Respective flow diagrams to find the overall energy and exergy efficiencies of Malaysian transportation sector are also presented. The estimated overall energy efficiency ranges from 22.74% (1999) to 22.98% (1998) with a mean of 22.82+/-0.06% and that of overall exergy efficiency ranges from 22.44% (2000) to 22.82% (1998) with a mean of 22.55+/-0.12%. The results are compared with respect to present energy and exergy efficiencies in each sub-sector. The transportation sector used about 40% of the total energy consumed in 2002. Therefore, it is important to identify the energy and exergy flows and the pertinent losses. The road sub-sector has appeared to be the most efficient one compared to the air and marine sub-sectors. Also found that the energy and exergy efficiencies of Malaysian transportation sector are lower than that of Turkey but higher than Norway

    The collective transportation system is essential to reduce the number of automobiles in the roads. Concerns exist related to quality, comfort and safety of bus driver's workstations. The objective of this study was to improve the driver's workstation in the private collective transportation sector by analyzing ergonomic practices using the Ergonomic Work Analysis (EWA). The EWA was chosen because it seeks to evaluate the labor condition as it relates to the psychophysiological conditions of workers, it complies with regulatory standard 17 (NR17). To identify driver concerns, interviews and questionnaires were administered. The workstation and worker routines were observed. The analysis revealed that the largest number of complaints related to noise, display light and location of the passenger identifier device. Drivers reported discomfort in the knees and lower back. Recommendations were made to improve the workstation and change the routine to minimize the discomfort and ergonomic risk factors.

    This report documents the objectives, analytical approach and development of the National Energy Modeling System (NEMS) Transportation Model (TRAN). The report catalogues and describes the model assumptions, computational methodology, parameter estimation techniques, model source code, and forecast results generated by the model. The NEMS Transportation Model comprises a series of semi-independent models which address different aspects of the transportation sector. The primary purpose of this model is to provide mid-term forecasts of transportation energy demand by fuel type including, but not limited to, motor gasoline, distillate, jet fuel, and alternative fuels (such as CNG) not commonly associated with transportation. The current NEMS forecast horizon extends to the year 2010 and uses 1990 as the base year. Forecasts are generated through the separate consideration of energy consumption within the various modes of transport, including: private and fleet light-duty vehicles; aircraft; marine, rail, and truck freight; and various modes with minor overall impacts, such as mass transit and recreational boating. This approach is useful in assessing the impacts of policy initiatives, legislative mandates which affect individual modes of travel, and technological developments. The model also provides forecasts of selected intermediate values which are generated in order to determine energy consumption. These elements include estimates of passenger travel demand by automobile, air, or mass transit; estimates of the efficiency with which that demand is met; projections of vehicle stocks and the penetration of new technologies; and estimates of the demand for freight transport which are linked to forecasts of industrial output. Following the estimation of energy demand, TRAN produces forecasts of vehicular emissions of the following pollutants by source: oxides of sulfur, oxides of nitrogen, total carbon, carbon dioxide, carbon monoxide, and volatile organic compounds.

    Modelling of atmospheric transport of heavy metals emitted from Polish power sector. Many studies have been conducted to investigate the atmospheric heavy metals contamination and its deposition to ecosystems. The increasing attention to mercury pollution has been mainly driven by the growing evidence of its negative impacts on wildlife, ecosystems and particularly human health. Lead and cadmium are also toxics which are being emitted into the atmosphere by anthropogenic as well as natural sources. The harmful influence of these three heavy metals was underlined in the Aarhus Protocol on Heavy Metals of 1998. The Parties of this protocol (including Poland) are obligated to reduce emissions, observe the transport and the amounts of lead, mercury and cadmium in the environment. Poland is one of the biggest emitter of mercury, lead and cadmium in Europe mainly due to emission from coal combustion processes. Therefore in Poland, research efforts to study the heavy metals emission, atmospheric transport, concentration and deposition are extremely important. The objectives of this work were twofold: - The practical objective was to develop and run a model to represent the atmospheric dispersion of mercury and to implement it in the air quality modelling platform Polyphemus.- The scientific objective was to perform heavy metals dispersion studies over Europe and detailed studies of the impact of the polish power sector on the air quality regarding mercury, cadmium and lead. To meet the declared aim, a new mercury chemical model was implemented into the Polyphemus air quality system. The scientific literature was reviewed regarding mercury chemistry and mercury chemical models. It can be concluded that the chemistry of mercury is still not well known. The models also differ in the way of calculating the dry and wet deposition of mercury. The elemental gaseous mercury ambient concentrations are evenly distributed, on the contrary, high variations in the spatial gradients of

    Proven reserves and production of natural gas (NG) in the United States have increased dramatically in the last decade, due largely to the commercialization of hydraulic fracturing. This has led to a plentiful supply of NG, resulting in a significantly lower cost on a gallon of gasoline-equivalent (GGE) basis. Additionally, NG is a domestic, non-petroleum source of energy that is less carbon-intensive than coal or petroleum products, and thus can lead to lower greenhouse gas emissions. Because of these factors, there is a desire to increase the use of NG in the transportation sector in the United States (U.S.). However, using NG directly in the transportation sector requires that several non-trivial challenges be overcome. One of these issues is the fueling infrastructure. There are currently only 1,375 NG fueling stations in the U.S. compared to 152,995 fueling stations for gasoline in 2014. Additionally, there are very few light-duty vehicles that can consume this fuel directly as dedicated or bi-fuel options. For example, in model year 2013Honda was the only OEM to offer a dedicated CNG sedan while a number of others offered CNG options as a preparation package for LD trucks and vans. In total, there were a total of 11 vehicle models in 2013 that could be purchased that could use natural gas directly. There are additional potential issues associated with NG vehicles as well. Compared to commercial refueling stations, the at-home refueling time for NG vehicles is substantial – a result of the small compressors used for home refilling. Additionally, the methane emissions from both refueling (leakage) and from tailpipe emissions (slip) from these vehicles can add to their GHG footprint, and while these emissions are not currently regulated it could be a barrier in the future, especially in scenarios with broad scale adoption of CNG vehicles. However, NG consumption already plays a large role in other sectors of the economy, including some that are important to

    It is well established that GHG emissions must be reduced 50 to 80% by 2050 in order to limit global temperature increase to 2 °C. Achieving reductions of this magnitude in the transportation sector is a challenge and requires a multitude of policies and technology options. The research presented here analyzes three scenarios: changes in the perceived price of travel, land use intensification, and increases in transit. Elasticity estimates are derived using an activity-based travel model for the state of California and broadly representative of the US. The VISION model is used to forecast changes in technology and fuel options that are currently forecast to occur in the US for the period 2000–2040, providing a life-cycle GHG forecast for the road transportation sector. Results suggest that aggressive policy action is required, especially pricing policies, but also more on the technology side, especially increases in the carbon efficiency of medium and heavy-duty vehicles. - Highlights: • Travel elasticities are calculated for policy scenarios using an activity-based travel model. • These elasticities are used to estimate changes in total life-cycle greenhouse gas emissions. • Current technology and fuel policy and the strongest behavioral policy will not meet targets. • Heavy and medium-duty trucks need more aggressive technology and fuel options

    Pump-to-wheels (PTW) methane emissions from the heavy-duty (HD) transportation sector, which have climate change implications, are poorly documented. In this study, methane emissions from HD natural gas fueled vehicles and the compressed natural gas (CNG) and liquefied natural gas (LNG) fueling stations that serve them were characterized. A novel measurement system was developed to quantify methane leaks and losses. Engine related emissions were characterized from twenty-two natural gas fueled transit buses, refuse trucks, and over-the-road (OTR) tractors. Losses from six LNG and eight CNG stations were characterized during compression, fuel delivery, storage, and from leaks. Cryogenic boil-off pressure rise and pressure control venting from LNG storage tanks were characterized using theoretical and empirical modeling. Field and laboratory observations of LNG storage tanks were used for model development and evaluation. PTW emissions were combined with a specific scenario to view emissions as a percent of throughput. Vehicle tailpipe and crankcase emissions were the highest sources of methane. Data from this research are being applied by the authors to develop models to forecast methane emissions from the future HD transportation sector.

    Full Text Available Indonesia faces serious energy problems; its status as an oil exporter has changed to that of a net oil importer. Additionally, a highly subsidized price of fossil fuels, combined with a high dependency on oil, burden Indonesia’s national budget. In 2006, the government enacted a Mix Energy Policy, which strives for a mixture of energy sources by introducing renewable energy into the existing energy systems. Among the several alternative renewable energy options, biofuel is perceived as having the most potential in Indonesia, due to favorable climate and the availability of land and technology. This paper assesses the impact of the introduction of biofuel in the transportation sector of Indonesia in terms of energy, economics and the environment. A linear programming model was built to simulate the impact of the introduction of biofuel. The author concludes that the introduction of biofuel may have a positive impact by partially replacing the oil used for domestic transportation, generating income due to export of excess production, creating jobs in several sectors, and reducing carbon emissions in a sustainable way. In the model, four scenarios are tested: under the scenario ‘land and technology’, with proper land allocation and technology development, biofuel production can reach 2,810 PJ/annum and reduce greenhouse gas emissions by 168 million tons/annum CO2-equivalent. Furthermore, a profit of 49 billion USD can be generated in 2025 (all maximum values.

    A decomposition analysis is used to investigate the main factors influencing the CO 2 emissions of European transport activities for the period 2001–2008. The decomposition method developed by Sun has been used to investigate the carbon dioxide emissions intensity, the energy intensity, the structural changes and the economy activity growth effects for the water and the aviation transport sectors. The analysis is based on Eurostat data and results are presented for 14 Member States, Norway and EU27. Results indicate that economic growth has been the main factor behind the carbon dioxide emissions increase in EU27 both for water and aviation transport activities. -- Highlights: ► Decomposition analysis is used to investigate factors that influenced the energy-related CO 2 emissions of European transport. ► Economic growth has been the main factor affecting the energy-related CO 2 emissions increases. ► Investigating the CO 2 emissions drivers is the first step to define energy efficiency policies and emission reduction strategies.

    The scope of the work described in this report was (1) to evaluate methods for risk mapping considering all of the different means of transport, (2) to evaluate the extent to which measures should be taken against various types of accidents, (3) to evaluate cost-benefit assessments of accident-reducing measures irrespective of the different means of transport, (4) to evaluate the preferences of measures/cost effectiveness of different measures within different sectors, and (4) to evaluate the possibility of improving the efficiency of possible measures. It also considers the risk situation for ferry service. In addition to the purely human aspect, traffic accidents constitute an expensive social problem. Yet it would be too costly to meet a potential requirement that traffic accidents should disappear. The resources used by society to combat accidents have to be seen in the light of (1) the profit that can be achieved compared to alternative use of the resources, and (2) the possible negative consequences of different safety measures on, for instance, travel time and the extent of the transport. It is pointed out that when accident risk is compared from one transport means to another, different relative positions are found depending on how risk is quantified.

  11. Analysis of CO2 emissions reduction in the Malaysian transportation sector: An optimisation approach

    International Nuclear Information System (INIS)

    Mustapa, Siti Indati; Bekhet, Hussain Ali

    2016-01-01

    The demand for transport services is expected to rise, causing the CO 2 emissions level to increase as well. In Malaysia, the transportation sector accounts for 28% of total CO 2 emissions, of which 85% comes from road transport. By 2020, Malaysia is targeting a reduction in CO 2 emissions intensity by up to 40% and in this effort the role of road transport is paramount. This paper attempts to investigate effective policy options that can assist Malaysia in reducing the CO 2 emissions level. An Optimisation model is developed to estimate the potential CO 2 emissions mitigation strategies for road transport by minimising the CO 2 emissions under the constraint of fuel cost and demand travel. Several mitigation strategies have been applied to analyse the effect of CO 2 emissions reduction potential. The results demonstrate that removal of fuel price subsidies can result in reductions of up to 652 ktonnes of fuel consumption and CO 2 emissions can be decreased by 6.55%, which would enable Malaysia to hit its target by 2020. CO 2 emissions can be reduced significantly, up to 20%, by employing a combination of mitigation policies in Malaysia. This suggests that appropriate mitigation policies can assist the country in its quest to achieve the CO 2 emissions reduction target. - Highlights: • An optimisation model for CO 2 emissions reduction in Malaysia's road transport is formulated. • Sensible policy options to achieve the CO 2 emissions reduction target are provided. • Increase in fuel price has induced shift towards fuel efficient vehicles. • The CO 2 emissions can be reduced up to 5.7 MtCO 2 with combination of mitigation policies.

    Full Text Available Delhi is the most urbanized city in India. Inventory estimates for the emissions of greenhouse gases and other pollutants like CO2, CO, NOx, and volatile organic compound from transport sector in Delhi, has been developed using bottom up approach provided by Intergovernmental panel on climate change (IPCC-1996. The impacts of policy option in transport sector like introduction of Compressed Natural Gas for public transport in Delhi and introduction of Euro-1 norms for vehicles have also been estimated. The emission inventory reveals that total emission of pollutants from different categories vehicles have increased during the period 1990-2000. For example, the CO2 emission (1000, tones from gasoline driven vehicle (MC/SC in Delhi has increased from 766 in 1990-91 to 1187 in 1999-00. The diesel driven vehicles Light commercial vehicles in Delhi has contributed to 577 CO2 in 1990-91, which increased to 9779 in 1999-00. For other pollutants also, which have been estimated here, an increase in total emission from gasoline and diesel driven vehicles has been observed during this 1990-2000 periods. This study shows that the over all contribution of pollutants in the total emissions from gasoline and diesel driven vehicles have increased in Delhi during this period. The present study also shows that the implementation of Euro-1 in 2000 in Delhi has resulted in the decrease of total emission of CO, HC, NOx, and volatile organic compound for all the classes of vehicle for which the revised vehicle emissions norms were implemented. However this decrease in emission has become inefficient due to increase in vehicle population.

  14. The peculiarities of process-based approach realization in transport sector company management

    Khripko, Elena; Sidorov, Gennadiy

    2017-10-01

    In the present article we study the phenomena of multiple meaning in understanding process-based management method in construction of transport infrastructure facilities. The idea of multiple meaning is in distortions which appear during reception of the management process paradigm in organizational environment of transport sector. The cause of distortion in process management is organizational resistance. The distortions of management processes are discovered at the level of diffusion among spheres of responsibility, collision in forms of functional, project and process interaction between the owner of the process and its participants. The level of distortion is affected by the attitude towards the result of work which means that process understanding of the result is replaced by the functional one in practice of management. This transfiguration is the consequence of regressive defensive mechanisms of the organizational environment. On the base of experience of forming process management in construction of transport infrastructure facilities company of the issues of diagnostics of various forms of organizational resistance and ways of reducing the destructive influence on managing processes are reviewed.

  15. Long-term developments in the transport sector -- comparing biofuel and hydrogen roadmaps

    In view of climate change and declining oil reserves, alternative fuels for transport receive increasing attention. Two promising options are biofuels, of which the market penetration has already started, and hydrogen, which, when used in fuel cell cars, could lead to zero-emission vehicles. This paper draws on the results of two ongoing EU projects in which roadmaps are being developed for respectively biofuels and hydrogen . The most important potential conflict lies in competition for biomass as a feedstock. In this context, the hydrogen-fuel cell route has the advantage of a higher efficiency (in terms of km driven per ha or tonne biomass) than biofuels. Furthermore, hydrogen is more flexible in feedstock, since it can also be produced in a climate-friendly way from fossil resources such as coal. Synergy between biofuels and hydrogen is in gasification technology. This technology is required both for biomass-to-liquids, one of the more promising biofuels, and for hydrogen production from biomass and/or coal. Our analysis indicates that the transportation sector will need both options in the long term: while hydrogen may become dominant for passenger cars, greening of long-distance heavy duty transport will become dependent on a bio-based diesel substitute.

  16. Are Chinese Green Transport Policies Effective? A New Perspective from Direct Pollution Rebound Effect, and Empirical Evidence From the Road Transport Sector

    Directory of Open Access Journals (Sweden)

    Lu-Yi Qiu

    2017-03-01

    Full Text Available Air pollution has become a serious challenge in China. Emissions from motor vehicles have been found to be one main sources of air pollution. Although the Chinese government has undertaken numerous green policies to mitigate harmful emissions from road transport sector, it is still uncertain for both policy makers and researchers to know whether the policies are effective in the short and long terms. We propose a new concept of “pollution rebound effect” (PRE to estimate the effectiveness of green traffic policies. We estimate direct air PRE as a measure of the effectiveness of the policies of reducing air pollution from the transport sector based on time-series data from the period 1986–2014. We find that the short-term direct air PRE is −0.4105, and the corresponding long-run PRE is −0.246. The negative results indicate that the direct air PRE does not exist in the road passenger transport sector in China, both in the short term and in the long term during the period 1986–2014. This implies that the Chinese green transport policies are effective in terms of harmful emissions reduction in the transport sector. This research, to the best of our knowledge, is the first attempt to quantify the effectiveness of the green transport policies in the transitional period that China is currently undergoing.

    The transport sector plays on essential role in our society, but generates non desired effects on the air quality as well on climate change. This is the reason why the transport and the environment governmental actions are crucial to mitigate them. In this article we introduced the most important resources and regulations to control and to evaluate the air quality and emissions, and also the most relevant objectives in transport actions to reduce them, not only in Spain but also in the European Union. We discuss herein their compliance degree and their effectiveness in relation with the transport emissions evolution during 1990-2006 in spain. (Author) 11 refs.

    Full Text Available The study aims at analyzing comparatively the representativeness of foreign capital in the capital of Brazilian companies of the sectors construction and transports, considering their segments on the BM&FBovespa. The internationalization of the 66 companies in the sample was measured by the percentage of the company's share capital held by foreign investors, and governance by the company's participation on the “Differentiated Level of Corporate Governance” (DLCG segments of BM&FBovespa. Using a descriptive and a quantitative study, the results of applying the Mann-Whitney test for the percentage of foreign capital in the capital of DLCG firms and of companies listed on the traditional market indicate that there is a difference statistically significant between the two groups of firms, confirming the hypothesis of this research. The conclusion is that governance is a sign of the internationalization of capital companies, confirming the efficiency of the administration based on the theory of transaction costs.

  1. China’s Energy Transition in the Power and Transport Sectors from a Substitution Perspective

    Directory of Open Access Journals (Sweden)

    2017-04-01

    Full Text Available Facing heavy air pollution, China needs to transition to a clean and sustainable energy system, especially in the power and transport sectors, which contribute the highest greenhouse gas (GHG emissions. The core of an energy transition is energy substitution and energy technology improvement. In this paper, we forecast the levelized cost of electricity (LCOE for power generation in 2030 in China. Cost-emission effectiveness of the substitution between new energy vehicles and conventional vehicles is also calculated in this study. The results indicate that solar photovoltaic (PV and wind power will be cost comparative in the future. New energy vehicles are more expensive than conventional vehicles due to their higher manufacturer suggested retail price (MSRP. The cost-emission effectiveness of the substitution between new energy vehicles and conventional vehicles would be $96.7/ton or $114.8/ton. Gasoline prices, taxes, and vehicle insurance will be good directions for policy implementation after the ending of subsidies.

  2. Evaluation of the energy efficiency evolution in the European road freight transport sector

    International Nuclear Information System (INIS)

    Ruzzenenti, F.; Basosi, R.

    2009-01-01

    In this paper, we evaluate energy efficiency in the European freight transport sector over three decades, according to a variety of indicators, methodologies and databases. The aim is, on the one hand, of determining major drawbacks in energy efficiency metrics, on the other hand, identifying a possible trend in the sector. The present analysis shows that energy efficiency evaluation is generally subject to misinterpretation and distortion with regard to the methods and data source adopted. Two different indicators (energy intensity and fuel economy) were initially taken into account to select the most suitable for evaluating vehicles' efficiency. Fuel economy was then adopted and measured according to two different methodologies (top-down and bottom-up). We then considered all the possible sources of distortion (data sources employed, methods of data detection, speed of detection, power enhancement, size factor) with the aim of accomplishing a sound estimation. Fuel economy was eventually divided with the maximum power available (adjusted fuel economy), to account for the power shift of vehicles, that represents a further efficiency improvement.

  3. An assessment of the market for LPG and CNG in Peru's transport sector

    International Nuclear Information System (INIS)

    Boykiw, A. L.

    1999-01-01

    This is an abridged version of the report prepared by Boykiw and Company Limited to provide a technical, statistical and financial assessment of potential sales of liquefied petroleum gases (LPG) or propane, and compressed natural gas (CNG) to the transportation sector in Peru. Results show that use of CNG and LPG in Peru's transportation sector will primarily be a function of the counrty's vehicle population, the economics of conversion and the availability of infrastructure. With regard to conversion, the fact that 62 per cent of the nation's one million vehicles are located in Lima, combined with their age, the prospects appear to be very favourable. Changing to LPG will also benefit the environment since carbon monoxide and nitrogen oxides emissions will be significantly reduced. Similar environmental benefits are expected from the use of CNG. Assuming that low cost first generation conversion kits can be made available, in combination with the growing refueling infrastructure ( from one in 1994 to 9 by the end of 1999, and an additional five in 2000) should result in a dramatic increase in the number of vehicles using LPG. By contrast, the prospect for CNG as vehicle fuel is less favourable because of the much more complex and costly refuelling station required to make it practicable. Based on very incomplete information on the Lima fleet of vehicles and their operating characteristics, the total number of CNG-fuelled vehicles five years after CNG becomes available in Lima, is estimated at between 2,000 and 3,000, and CNG requirements of between 800,000 and 1,500,000 cubic feet per day

  4. The impact of CO{sub 2} emissions trading on the European transport sector

    Energy Technology Data Exchange (ETDEWEB)

    Kaageson, Per

    2001-07-01

    The objective of this report is to analyse how a common European scheme for CO{sub 2} emissions trading covering all sectors of society would affect the transport sector. Transport externalities other than CO{sub 2} are assumed to be internalised by kilometer charging. This means road fuels will no longer be subject to taxation. The European Union's commitment under the 1997 Kyoto Protocol can be reached at a marginal abatement cost around 65 Euro per tonne of CO{sub 2} in a case where emissions trading replaces all current taxes on fossil fuels. In a case where emissions trading is supplementary to today's energy and carbon taxes, the current average taxation (45-50 Euro per tonne CO{sub 2}) and the shadow price of the emission permits (33 Euro per tonne) would together give a total marginal abatement cost around 80 Euro per tonne Of CO{sub 2}. Having to buy emission permits would significantly raise the cost of fuel and electricity used in rail, aviation and short sea shipping, as these modes are currently not taxed at all. The resulting long-term (2025) improvement in specific energy efficiency is estimated at around 25 per cent compared to trend for rail and 20 and 40 per cent respectively for aviation and sea transport. A combination of CO{sub 2} emissions trading and km charging would moderately raise the variable cost of driving a gasoline car. The cost of using diesel vehicles would rise considerably in most Member States. Annual mileage per car would therefore decline somewhat. The fuel, however, would become cheaper than today (especially gasoline) and this would reduce the incentive to buy fuel-efficient vehicles. The reform would thus hamper the introduction of new, more efficient, technologies that might be needed for meeting more long-term commitments. Emissions trading would not encourage the introduction of biofuels in road transport. The incremental cost of producing ethanol or RME is much too high and cannot be expected to fall to the

    The aim of Switzerland is to stabilize the CO 2 emissions by year 2000 and to reduce them from 20 pc by 2005 and from 50 pc by 2025. In order to attain these objectives, several measures should be taken: in the residential sector, the heating appliances (space heating and hot water production) should be efficiency-enhanced and an individual counting system should be used; energy audits should be enforced in industry; in the transportation sector, railway transportation should be enhanced and a pollution tax on automobile fuel should be applied

  6. Global emission projections for the transportation sector using dynamic technology modeling

    2014-06-01

    In this study, global emissions of gases and particles from the transportation sector are projected from the year 2010 to 2050. The Speciated Pollutant Emission Wizard (SPEW)-Trend model, a dynamic model that links the emitter population to its emission characteristics, is used to project emissions from on-road vehicles and non-road engines. Unlike previous models of global emission estimates, SPEW-Trend incorporates considerable detail on the technology stock and builds explicit relationships between socioeconomic drivers and technological changes, such that the vehicle fleet and the vehicle technology shares change dynamically in response to economic development. Emissions from shipping, aviation, and rail are estimated based on other studies so that the final results encompass the entire transportation sector. The emission projections are driven by four commonly-used IPCC (Intergovernmental Panel on Climate Change) scenarios (A1B, A2, B1, and B2). With global fossil-fuel use (oil and coal) in the transportation sector in the range of 128-171 EJ across the four scenarios, global emissions are projected to be 101-138 Tg of carbon monoxide (CO), 44-54 Tg of nitrogen oxides (NOx), 14-18 Tg of non-methane total hydrocarbons (THC), and 3.6-4.4 Tg of particulate matter (PM) in the year 2030. At the global level, a common feature of the emission scenarios is a projected decline in emissions during the first one or two decades (2010-2030), because the effects of stringent emission standards offset the growth in fuel use. Emissions increase slightly in some scenarios after 2030, because of the fast growth of on-road vehicles with lax or no emission standards in Africa and increasing emissions from non-road gasoline engines and shipping. On-road vehicles and non-road engines contribute the most to global CO and THC emissions, while on-road vehicles and shipping contribute the most to NOx and PM emissions. At the regional level, Latin America and East Asia are the two

    2015-01-01

    The German government has set targets to reduce greenhouse gas emissions by 40% by 2020, 55% by 2030, 70% by 2040 and 80-95% by 2050 compared to 1990 as reference year. As well as meeting other requirements, these targets can be achieved by raising the contribution of renewably-generated power to Germany's gross electricity consumption to 80% by 2050. Based on Germany's potential, intermittent energy sources (IES) such as on- and offshore wind, as well as photovoltaics, are necessary sources that must be utilized in order to achieve these ambitious targets. Because of the intermittency of these sources, there will be times in which surplus power generated could be used for example for the transport sector. During these periods of surplus power, the storage capacity of hydrogen allows for a socalled ''power-to-gas'' concept whereby the surplus power can be used to produce hydrogen and oxygen by means of electrolyzers. The aim of this thesis is to identify and develop a market design that is characterized by high penetration levels of IES, supplemented by the use of hydrogen in the transport sector. Furthermore, the aim was to develop a model in which the electricity and gas sector, including a hydrogen pipeline grid, is represented so as to analyze and validate selected market designs. Therefore, potential electricity and gas markets, as well as the most important potential share and stakeholders of a hydrogen infrastructure, are analyzed. With the model developed in this thesis, an existing energy concept has been developed, analyzed and evaluated. In addition, the distribution of the hydrogen production costs was calculated by employing a Monte Carlo Simulation analysis. The developed energy concept relies on 170 GW onshore and 60 GW offshore wind capacity and these dominate the model. This leads to surplus power, especially in the federal states of Lower Saxony, Schleswig-Holstein and Mecklenburg-Western Pomerania. To supply the

    International Nuclear Information System (INIS)

    2017-11-01

    Reaching the ambitious climate objective of the Paris Agreement requires decreasing significantly sectoral emissions from the transport sector. However, the ambition pledged for the transport sector under the Nationally Determined Contributions (NDCs) remains very limited. The DDPP-T analyzes Paris-compatible sectoral strategies for the passenger transport that can serve to inform the 2018 Facilitative Dialogue and the preparation of future, more ambitious, NDCs by 2020. In a context of an expected steep increase in global mobility demand, deep decarbonization will require a mix of different 'well-known' options: the rapid diffusion of low-carbon vehicles and low-carbon fuels and the modal shift towards low-carbon modes like public transport and non-motorized transport (cycling and walking). However, while crucial, these options are not 'silver bullets' that on their own meet the decarbonization challenge, given their intrinsic individual limitations. The project adopts an integrated approach of sectoral deep decarbonization strategies articulating the diffusion of low-carbon technologies with the future of mobility and all its drivers, such as the demographic and economic situation, the localization of population centers, the transport and urban planning, the lifestyles and the features of mobility services. The strategies are context-specific in order to capture different country circumstances, and consider a long-term horizon to inform the short-term conditions enabling structural changes of the transport system. Building on four country analyses (France, Japan, Mexico and the United Kingdom), this Issue Brief derives five cross-cutting messages for a deep decarbonization of the passenger transport sector. Key messages: - Deep decarbonization of the passenger transport sector requires strong actions on four pillars of transformation. Only a consistent articulation of these synergistic pillars allows an effective deep decarbonization. - Deep

    2017-11-01

    The aim of this study was to identify an optimal CCS transport infrastructure for Polish energy sector in regards of selected European Commission Energy Roadmap 2050 scenario. The work covers identification of the offshore storage site location, CO2 pipeline network design and sizing for deployment at a national scale along with CAPEX analysis. It was conducted for the worst-case scenario, wherein the power plants operate under full-load conditions. The input data for the evaluation of CO2 flow rates (flue gas composition) were taken from the selected cogeneration plant with the maximum electric capacity of 620 MW and the results were extrapolated from these data given the power outputs of the remaining units. A graph search algorithm was employed to estimate pipeline infrastructure costs to transport 95 MT of CO2 annually, which amount to about 612.6 M€. Additional pipeline infrastructure costs will have to be incurred after 9 years of operation of the system due to limited storage site capacity. The results show that CAPEX estimates for CO2 pipeline infrastructure cannot be relied on natural gas infrastructure data, since both systems exhibit differences in pipe wall thickness that affects material cost.

    Black carbon is one of the most important short-lived climate-forcing agents, which is harmful to human health and also contributes significantly to climate change. Transportation is one of the largest sources of black carbon emissions in many megacities and urban complexes, with diesel vehicles leading the way. Both on-road and off-road vehicles can emit substantial amounts of harmful BC-containing particulate matter (PM) and are also responsible for large emissions of carbon dioxide (CO2), carbon monoxide (CO), nitrogen oxides (NOx), and many other co-emitted volatile organic compounds (VOCs). Regionally, black carbon emissions contributions from mobile sources may vary widely depending on the technical characteristics of the vehicle fleet, the quality and chemical properties of the fuels consumed, and the degree of local development and economic activities that foster wider and more frequent or intensive use of vehicles. This presentation will review and assess the emissions of black carbon from the on-road and off-road transportation sector in the Mexico City Metropolitan Area. Viable mitigation strategies, including innovative technological alternatives to reduce black carbon and co-pollutants in diesel vehicles and their impacts on climate, human health and ecosystems will be described.

    2008-01-01

    Large-scale sustainable energy systems will be necessary for substantial reduction of CO 2 . However, large-scale implementation faces two major problems: (1) we must replace oil in the transportation sector, and (2) since today's inexpensive and abundant renewable energy resources have fluctuating output, to increase the fraction of electricity from them, we must learn to maintain a balance between demand and supply. Plug-in electric vehicles (EVs) could reduce or eliminate oil for the light vehicle fleet. Adding 'vehicle-to-grid' (V2G) technology to EVs can provide storage, matching the time of generation to time of load. Two national energy systems are modelled, one for Denmark, including combined heat and power (CHP) and the other a similarly sized country without CHP (the latter being more typical of other industrialized countries). The model (EnergyPLAN) integrates energy for electricity, transport and heat, includes hourly fluctuations in human needs and the environment (wind resource and weather-driven need for heat). Four types of vehicle fleets are modelled, under levels of wind penetration varying from 0% to 100%. EVs were assumed to have high power (10 kW) connections, which provide important flexibility in time and duration of charging. We find that adding EVs and V2G to these national energy systems allows integration of much higher levels of wind electricity without excess electric production, and also greatly reduces national CO 2 emissions

    1995-03-01

    The purpose of this report is to study the technical and economic prerequisites to attain reduced carbon dioxide emissions through the use of biomass-based energy carriers in the transportation sector, and to study other environmental impacts resulting from an increased use of biomass-based energy carriers. CO{sub 2} emission reduction per unit arable and forest land used for biomass production (kg CO{sub 2}/ha,year) and costs for CO{sub 2} emission reduction (SEK/kg CO{sub 2}) are estimated for the substitution of gasoline and diesel with rape methyl ester, biogas from lucerne, ethanol from wheat and ethanol, methanol, hydrogen and electricity from Salix and logging residues. Of the studied energy carriers, those based on Salix provide the largest CO{sub 2} emission reduction. In a medium long perspective, the costs for CO{sub 2} emission reduction seem to be lowest for methanol from Salix and logging residues. The use of fuel cell vehicles, using methanol or hydrogen as energy carriers, can in a longer perspective provide more energy efficient utilization of biomass for transportation than the use of internal combustion engine vehicles. 136 refs, 12 figs, 25 tabs

    Science.gov (United States)

    Miller, James

    As worldwide environmental consciousness grows, electric vehicles (EVs) are becoming more common and despite the incredible potential for emissions reduction, the net emissions of the power system supply side plus the transportation system are dependent on the generation matrix. Current EV charging patterns tend to correspond directly with the peak consumption hours and have the potential to increase demand sharply allowing for only a small penetration of Electric Vehicles. Using the National Household Travel Survey (NHTS) data a model is created for vehicle travel patterns using trip chaining. Charging schemes are modeled to include uncontrolled residential, uncontrolled residential/industrial charging, optimized charging and optimized charging with vehicle to grid discharging. A charging profile is then determined based upon the assumption that electric vehicles would directly replace a percentage of standard petroleum-fueled vehicles in a known system. Using the generation profile for the specified region, a unit commitment model is created to establish not only the generation dispatch, but also the net CO2 profile for variable EV penetrations and charging profiles. This model is then used to assess the impact of the electrification of the road transport sector on the system net emissions.

    The DOE is conducting a comprehensive technical analysis of a flexible-fuel transportation system in the United States -- that is, a system that could easily switch between petroleum and another fuel, depending on price and availability. The DOE Alternative Fuels Assessment is aimed directly at questions of energy security and fuel availability, but covers a wide range of issues. This report examines environmental, health, and safety concerns associated with a switch to alternative- and flexible-fuel vehicles. Three potential alternatives to oil-based fuels in the transportation sector are considered: methanol, compressed natural gas (CNG), and electricity. The objective is to describe and discuss qualitatively potential environmental, health, and safety issues that would accompany widespread use of these three fuels. This report presents the results of exhaustive literature reviews; discussions with specialists in the vehicular and fuel-production industries and with Federal, State, and local officials; and recent information from in-use fleet tests. Each chapter deals with the end-use and process emissions of air pollutants, presenting an overview of the potential air pollution contribution of the fuel --relative to that of gasoline and diesel fuel -- in various applications. Carbon monoxide, particulate matter, ozone precursors, and carbon dioxide are emphasized. 67 refs., 6 figs. , 8 tabs

    Full Text Available The paper addresses the effect of external integration (EI with transport suppliers on the efficiency of travel agencies in the tourism sector supply chains. The main aim is the comparison of different estimation methods used in the structural equation modeling (SEM, applied to discover possible relationships between EIs and efficiencies. The latter are calculated by the means of data envelopment analysis (DEA. While designing the structural equation model, the exploratory and confirmatory factor analyses are also used as preliminary statistical procedures. For the estimation of parameters of SEM model, three different methods are explained, analyzed and compared: maximum likelihood (ML method, Bayesian Markov Chain Monte Carlo (BMCMC method, and unweighted least squares (ULS method. The study reveals that all estimation methods calculate comparable estimated parameters. The results also give an evidence of good model fit performance. Besides, the research confirms that the amplified external integration with transport providers leads to increased efficiency of travel agencies, which might be a very interesting finding for the operational management.

    Energy saving and carbon dioxide emission reduction in China is attracting increasing attention worldwide. At present, China is in the phase of rapid urbanization and industrialization, which is characterized by rapid growth of energy consumption. China's transport sector is highly energy-consuming and pollution-intensive. Between 1980 and 2012, the carbon dioxide emissions in China's transport sector increased approximately 9.7 times, with an average annual growth rate of 7.4%. Identifying the driving forces of the increase in carbon dioxide emissions in the transport sector is vital to developing effective environmental policies. This study uses Vector Autoregressive model to analyze the influencing factors of the changes in carbon dioxide emissions in the sector. The results show that energy efficiency plays a dominant role in reducing carbon dioxide emissions. Private vehicles have more impact on emission reduction than cargo turnover due to the surge in private car population and its low energy efficiency. Urbanization also has significant effect on carbon dioxide emissions because of large-scale population movements and the transformation of the industrial structure. These findings are important for the relevant authorities in China in developing appropriate energy policy and planning for the transport sector. - Highlights: • The driving forces of CO 2 emissions in China's transport sector were investigated. • Energy efficiency plays a dominant role in reducing carbon dioxide emissions. • Urbanization has significant effect on CO 2 emissions due to large-scale migration. • The role of private cars in reducing emissions is more important than cargo turnover

    This report contains statistics and indicators for the transport sector that show the relationships between the environment and transport. Norwegian data are compared to international data. In 2008, the average daily per capita distance driven by passenger cars in Norway was 32.4 kilometres. Among the European countries, Italy had the longest daily per capita distance driven by passenger cars, 33.1 km. In 2009, the total transport demand of passenger cars in Norway was 58.3 billion passenger kilometres. This is well over ten times higher than in 1960. In 2008, the statistics show a decrease by 2 per cent in freight transport demand on road in the EU. The decrease continued with an additional decrease of 10 per cent in 2009. The financial crisis had a negative impact on the freight transport demand in Norway also, but not before 2009, when the production decreased at the same rate as in the EU. By the end of 2010, the vehicle fleet in Norway had increased to around 3.2 million, of which over 2.3 million were passenger cars. In 2009, there were 462 passenger cars per 1 000 inhabitants in Norway. In Italy there were 606, the highest in Europe. By the end of 2010, the number of diesel passenger cars were a little over 807 000, which corresponded to 35 per cent of the total number of passenger cars. The number of gasoline driven passenger cars has decreased steadily from 2004. At the end of 2010, the average age of passenger cars in Norway was 10.5 years. Gasoline driven cars had an average age of 13.0 years and diesel cars only 5.9 years. A total of 98 662 passenger cars and vans were scrapped in 2010. The average age of scrapped passenger cars was 18.4 years. As of 31 December 2010, the length of public roads in Norway was 93 509 km, of which 381 km are motorways. This is by far the shortest motorway length in the Nordic countries. The length of railways in Norway is a little over 4 000 km.

    Full Text Available As the recent withdrawal of the United States from the Paris Agreement has shown, political volatility directly affects climate change mitigation policies, in particular in sectors, such as transport associated with long-term investments by individuals (vehicles and by local and national governments (urban form and transport infrastructure and services. There is a large potential for cost-effective solutions to reduce greenhouse gas emissions and to improve the sustainability of the transport sector that is yet unexploited. Considering the cost-effectiveness and the potential for co-benefits, it is hard to understand why efficiency gains and CO2 emission reductions in the transport sector are still lagging behind this potential. Particularly interesting is the fact that there is substantial difference among countries with relatively similar economic performances in the development of their transport CO2 emissions over the past thirty years despite the fact that these countries had relatively similar access to efficient technologies and vehicles. This study aims to explore some well-established political science theories on the particular example of climate change mitigation in the transport sector in order to identify some of the factors that could help explain the variations in success of policies and strategies in this sector. The analysis suggests that institutional arrangements that contribute to consensus building in the political process provide a high level of political and policy stability which is vital to long-term changes in energy end-use sectors that rely on long-term investments. However, there is no direct correlation between institutional structures, e.g., corporatism and success in reducing greenhouse gas emissions in the transport sector. Environmental objectives need to be built into the consensus-based policy structure before actual policy progress can be observed. This usually takes longer in consensus democracies than in

    This study presents a methodology to develop scenarios of evolution from 2010 to 2050, for energy consumption and emissions (CO 2 , HC, CO, NO x , PM) of the road transportation sector (light-duty and heavy-duty vehicles). The methodology is applied to Portugal and results are analyzed in a life-cycle perspective. A BAU trend and 5 additional scenarios are explored: Policy-based (Portuguese political targets considered); Liquid fuels-based (dependency on liquid fuels and no deployment of alternative refueling infrastructure); Diversified (introduction of a wide diversity of alternative vehicle technology/energy sources); Electricity vision (deployment of a wide spread electricity recharging infrastructure); Hydrogen pathway (a broad hydrogen refueling infrastructure is deployed). Total life-cycle energy consumption could decrease between 2 and 66% in 2050 relatively to 2010, while CO 2 emissions will decrease between 7 and 73% in 2050 relatively to 2010. In 2050 the BAU scenario remains 30% above the 1990 level for energy consumption and CO 2 emissions; the other considered scenarios lead to 4 to 29% reductions for energy consumption and 10 to 33% for CO 2 emissions in 2050 compared to the BAU. Therefore, alternative vehicle technologies are required in the long-term, but changes in taxation and alternative transportation modes policies are crucial for achieving short-term impacts. - Highlight: ► Assess future energy consumption and emissions scenarios for road transportation. ► LCA energy consumption could decrease 2 to 66% in 2050 relatively to 2010. ► Alternative vehicle technologies can help to lower the BAU scenario impacts. ► Different deployments of alternative technologies can lead to similar impacts.

    The transport sector of a country is the backbone driving the economy forward. Thailand’s land transport sector is modelled using the AIM/Enduse, which is a recursive dynamic optimization model, based on bottom-up modelling principle. The travel demand is divided into two major categories which are passenger travel and freight travel. The objective of this paper is to analyse the mitigation possible through low carbon society (LCS) measures and emission tax (ET). Two scenario clusters are devised along with the BAU case. The LCS scenario cluster has three designed scenarios which are LCS-L, LCS-M and LCS-H. The emission tax (ET) cluster has four scenarios, where the taxes of 50, 100, 200 and 500 USD/t-CO 2 are implemented. Along with this the marginal abatement costs (MAC) of the counter-measures (CMs) and the co-benefits in terms of energy security, productivity and air pollutant mitigation are also assessed. Results show that LCS scenarios are possible of mitigating up to 1230 Mt-CO 2 cumulatively, from 2010 to 2050. In terms of MACs, new vehicles play a pivotal role, along with hybrid vehicles. The Average Abatement Cost (AAC) assessment shows that the AAC of LCS-H scenario is in the order of 100 USD/t-CO 2 . All the LCS and ET scenarios show an enhancement in energy security and also a threefold increase in productivity. There is distinct mitigation in terms of air pollutants from the transport sector as well. -- Highlights: •Thailand transport sector has been modelled using AIM/Enduse model. •Potential cumulative mitigation of CO 2 during 2010–2050 is approximately 30% when compared the BAU scenario. •Abatement cost curves show that various counter measures are practical in the transport sector. •Energy security is enhanced due to CO 2 mitigation in the LCS scenario

    The following report evaluates the efficiency of gas fuelled and electric driven buses in the public transport sector on a theoretical basis. The results indicate that the combination of CHP power plants and electric driven buses reach an overall efficiency of about 51% throughout the production chain (Well-to-Wheel), including heat distribution losses. The overall Well-to-Wheel efficiency for conventional gas turbines without heat recovery decreases to around 28%. For gas fuelled buses the Well-to-Wheel efficiency is about 30%. The Co2-emissions are evaluated based on the example of a #Left Double Quotation Mark#Volvo B10L CNG#Right Double Quotation Mark# gas bus and the electric driven #Left Double Quotation Mark#Eurabus 600#Right Double Quotation Mark#. The low energy consumption of the electric driven bus results in Co2-emissions of only 181.4 g Co2/km (Grid-to-Wheel). Depending on the utilised power plant technology the overall Co2-emissions (Well-to-Wheel) amount to 307.5 g Co2/km for a CHP power plant and 553.5 g Co2/km for a conventional gas turbine. On the other hand, gas fuelled buses emit about 1.25 kg Co2/km (Tank-to-Wheel), which is eightfold the emissions of an electrical bus. The Well-to-Tank emissions further increase to about 1.32 kg Co2/km. The emission calculation is based on real gas consumption data from a Norwegian public transport utility. The results indicate that the combination of CHP plants and electrical buses provide a much higher efficiency while reducing Co2-emissions. (author)

    Full Text Available Purpose: The main purpose of the present study is to conduct a literature review of the contribution made by safety in air transport, based on the existing international academic literature in the field of the social sciences. It primarily attempts to examine and verify the relationship between safety-related concepts (co-occurrence, the link between the different authors (co-authorship and the corresponding citations (co-citations. Methodology: To achieve the established objectives, a systematic literature review (SLR has been conducted using the Scopus database between the years 1990 and 2016, identifying international academic papers related to the research topic of the present study. Findings: It has been verified, on the one hand, that safety in the air transport sector is a field of growing interest, as the number of papers has increased considerably in recent years, thus demonstrating the importance that this topic has acquired over time. On the other hand, however, it must be mentioned that the total quantity of papers related to the topic is low in terms of absolute numbers. The results of the co-occurrence analysis show that the most important aspect of safety is safety management, while the strongest link is between safety management and aircraft accidents, a fact that is foreseeable a priori.  Originality/value: The approach used allows a better view of the academic contribution made in relation to safety; this serves as the link among the different elements of the concept studied, and it demonstrates the growing interest in this area.

    2012-07-01

    Changes in the world energy context, the increasing awareness of the environmental stakes and the development of research on the production of second and third generation biofuels revealed a clear need to write a new book which updates and complements all technical, financial and environmental aspects of Les Biocarburants - etat des lieux, perspectives et enjeux du developpement (Biofuels - Current status, outlook and development stakes) published in 2006. This book provides a detailed state of the art of the first generation biofuel production technologies. It describes the new 'second generation' pathways which use lignocellulosic biomass as raw material and are starting to find industrial applications, thereby reducing the competition between the food resource and the use of agricultural materials for energy purposes. It also provides a technical update on the algae-to-energy pathway (third generation) and the production of methane and hydrogen by biochemical pathways. The book arrives at exactly the right time to renew the interest in biofuels, including for air transport, and provide an insight on the technological research and development axes currently being investigated. It is intended for transport companies, refiners, forestry companies, the agricultural and agribusiness sectors as well as the public authorities, students, university teachers and researchers.

    Full Text Available Modeling of long-term forecasts of prices and demand on regional energy markets requires accounting for the future changes in the interactions between the greater economy and its energy sector, along with the possible emergence of new factors and specific regional features determining those interactions. The proposed approach allows the study of a correlation between demand and prices for motor fuel, taking into account the competition of energy carriers, the dynamics of energy prices, resource constraints, the use of new technologies and the uncertainty of input data. The main feature of the proposed approach is the combined estimation of the price elasticity of demand for motor fuel with optimization of fuel supply in the region. Thus the author determined elasticity of demand based on the comparison of economic efficiency of the use of different fuels. The study includes results of experimental calculations and forecasted price according to demand for motor fuel in freight transportation for the expected development conditions of the Far Eastern federal district

  6. Electrification of the transportation sector: Is there a need for restructuring the automotive parts suppliers?

    Bekaslan, A. Ebru

    The future of the transportation sector has significant implications for the mitigation of climate change through reduced GHG emissions as well as achieving energy efficiency and energy independence. Battery-powered, plug-in, and hybrid electric vehicles are widely seen as the greatest source of a solution. This thesis analyzes the historical development and growth of the automotive industry as well as the restructuring toward the next generation technologies in comparison with the U.S. and China to shed light on the question of how a developing country can structure its strategies to be able to upgrade and be competitive over time. Conventional business models can become obsolete. Companies will find it difficult to maintain their market position unless they gain new perspectives on the outlook of the industry as a whole, and take into account the successful business models of tomorrow. The potential for further growth of the Turkish automotive supplier base particularly in the next generation of automotive technologies is therefore highly dependent on policies and strategies at the national level as much as its dependence on the global strategies of the automotive industry's major players. In this sense, the key questions that motivate this study are whether there are foreseeable technological changes and product-segmentation strategies that could significantly enhance the competitiveness of local Turkish suppliers of automotive components. The thesis builds on the theory of innovative enterprise and evolutionary agglomeration to examine the competitive potential of the Konya Auto Part Suppliers' Cluster in Turkey.

    With the abatement potential of end-of-pipe technologies for road transport becoming increasingly marginal, and with greater emissions reductions still needed in order to reduce pollution, alternative strategies involving behavioural change and choices between fossil fuelled or low carbon vehicles becomes more important. The environmental requirements include local air quality objectives, meeting national emissions ceilings to limit transboundary effects, and to aspire to significant reductions in greenhouse gas emissions. In this paper we use the BRUTAL sub-model of the UK integrated Assessment Model (UKIAM) to investigate a selection of alternative strategies including downsizing of cars, switching from petrol to diesel, and the introduction of electric, bio-fuelled or hydrogen vehicles into the fleet, relative to a business-as-usual projection for 2020. Projected impacts upon air quality limit values, national emissions ceilings and CO 2 emissions are assessed in relation to local, national and international objectives. We discuss related life-cycle impacts, implications for infrastructure, and potential impacts upon emissions from other sectors in order to highlight the full potential implications of the different strategies within the context of changes resulting from other policy developments at different scales.

    The last 20 years efforts to find a long-term and large-scale biofuel alternative to petrol and diesel for the transport sector have been intensified with a focus on liquid biofuels, such as ethanol, methanol and Fischer-Tropsh diesel derived from wood. The large-scale production of biomethane has so far largely been overlooked in comparative studies that focus on the long-term renewable options. The aim of this article fills this gap and to provide a broad and systematic assessment of the future potential of biomethane compared to other biofuels. In order to become a large-scale option, biomethane production from woody biomass via gasification needs to be developed and commercialized. However, biomethane exhibits a clear development path with relatively low financial and technical risks starting with local solutions utilizing wet biomass resources towards medium and eventually large-scale gasification with economics similar to liquid second generation biofuels. The disadvantage of being a gaseous fuel is not insurmountable and can furthermore be relaxed by the integration and dual-use of the existing distribution system for natural gas. This assessment concludes that more emphasize should be given to biomethane as a large-scale option given the opportunity to use woody biomass from gasification.

    Public policies addressing the reduction of the greenhouse gases emission have to give response to the improvement of mobility in three aspects: passengers, freights, and urban and metropolitan areas. Passenger transport, because it involves long transportation distances consuming an important part of transport energy and raises difficult organizational problems. Freight transport, due to the complexity of interconnecting a lot of modes of transportation and the big range for improvement. Urban and metropolitan mobility, by the impact of actions in this field in the quality of life of a big part of the population. According to the peculiarities of their respective territories, different strategies of sustainable mobility that address the three considered aspects have been set up in Spain and its neighbouring countries. This article reviews some action lines implemented in spain, France and Germany, as a previous step to assess their possible adaptation to other territories. (Author) 6 refs.

    Nobody can doubt today that hydrogen will, in the not-too-distant future, represent a very significant percentage of the total energy used by the transport sector. This study therefore consists of the modelling and simulation of energy consumption, by type of vehicle and fuel or energetic vector, in the road transport sector of the Madrid Region, during the period 2010-2050, using the MARKAL model. It has been necessary to complete this model by adding numerous specifications in order to determine the features of the Madrid Region, the richest Region in Spain. For the purpose of the study, three growth scenarios, based on short-term energy forecasts made by different official organizations, have been proposed for the energy consumption of the road transport sector in the Region. The results show a profound change in the current situation as there is a significant decrease in the consumption of fossil fuels and an increase in that of alternative non-fossil fuels and hydrogen. The latter, in particular, will rise from 0.1% in the year 2010, to around 50% in the year 2050, which will mean a drastic drop in the sector's CO 2 and atmospheric pollutant emissions. (author)

    Even as the US debates an economy-wide CO 2 cap-and-trade policy the transportation sector remains a significant oil security and climate change concern. Transportation alone consumes the majority of the US's imported oil and produces a third of total US Greenhouse-Gas (GHG) emissions. This study examines different sector-specific policy scenarios for reducing GHG emissions and oil consumption in the US transportation sector under economy-wide CO 2 prices. The 2009 version of the Energy Information Administration's (EIA) National Energy Modeling System (NEMS), a general equilibrium model of US energy markets, enables quantitative estimates of the impact of economy-wide CO 2 prices and various transportation-specific policy options. We analyze fuel taxes, continued increases in fuel economy standards, and purchase tax credits for new vehicle purchases, as well as the impacts of combining these policies. All policy scenarios modeled fail to meet the Obama administration's goal of reducing GHG emissions 14% below 2005 levels by 2020. Purchase tax credits are expensive and ineffective at reducing emissions, while the largest reductions in GHG emissions result from increasing the cost of driving, thereby damping growth in vehicle miles traveled.

In Europe, this share of transports GHG emissions rises to 21% and emissions are forecast to rise. Against this background, should the road transport sector be included in the European Union Emissions Trading Scheme and thereby contribute to national GHG emission reduction targets? (authors)

  16. The use of ethanol from sugar cane in the Brazilian transport sector

    1999-01-01

    The use of Ethanol as a fuel is a significant contribution to the efforts for reducing greenhouse effect related to gas emissions. The main objective of the present work, is to assess Brazil's performance regarding activities aimed at reducing harmful gas emissions, in the global context of the intensification of the greenhouse effect, assumed as a working hypothesis. Brazil's estimated emissions of greenhouse effect related to gases are far less than those of developed countries. The per capita consumption of energy and of fossil fuels is still quite low in Brazil. However, the means for reducing harmful gas emissions and the initiatives to control the greenhouse effect should not be directed to the maintenance of the present low level of energy consumption, for this would have negative repercussion on the economic development of the country. Developed countries have focused on the more rational uses of energy, i.e. more efficient and less polluting fuels, so as to reduce their own levels of greenhouse effect related to gas emissions. In this connection, the use of ethanol in Brazil for the transportation sector may prove to be an important alternative furthering the efforts to stabilised the actual level of gases in the atmosphere. The energy derived from biomass, and in this case, from a renewable, clean source, i.e., from sugar cane, has the unquestionable advantage of permitting the almost complete reabsorption of Carbon Dioxide emitted through the combustion of fuel alcohol. This closed cycle allows, in principle, to increase the energy supply, essential for sustained economic growth, without hazards to the environment. Furthermore, the Brazilian Fuel Alcohol Program has the potential to attract international interest as an important alternative relative to the efforts for controlling the global dangers of the greenhouse effect, as will be discussed in greater detail further on in this paper.

    Full Text Available Warm Sector Torrential Rains (WSTRs occurring during the outbreak of the monsoon in May of 2015 in South China were studied using surface automatic weather observational data, sounding, European Centre for Medium-Range Weather Forecasts Reanalysis interim Data (ERA-interim, satellite and radar data, and a four-level nested grid simulation with the finest grid spacing of 1 km using the Weather Research and Forecasting model (WRF. The results show that the extreme precipitation event, which had maximum rainfall amounts of 406.3 mm in 10 h and 542.2 mm in 24 h on 20 May 2015, and was characterized by its rapid development and its highly concentrated and long duration of heavy rainfall, occurred over the trumpet-shaped topography of Haifeng. The simulation results indicated that the South China Sea (SCS atmospheric moisture transportation (AMT was crucial in triggering the precipitation of the WSTR over South China. The simulation of the WSTR was conducted by using the total energy-mass flux scheme (TEMF, which provided a reasonable simulation of the circulation and the vertical profile in the Planetary Boundary Layer (PBL as well as the estimation of the precipitation. The AMT, which extends from the Beibu Gulf and the South China Sea to the coastal areas and provides Shanwei with a considerable amount of moisture in the boundary layer, and the effects within the PBL, which include orographic effects, an extra low-level jet, and a high-energy tongue characterized by a high-potential pseudo-equivalent temperature tongue with a warm and moist southwesterly wind, were the important large-scale factors causing the WSTR.

  18. Economic analysis of the expected environmental impact of the Single European Market through the transport, waste and energy sectors

    Brutscher, S.

    1993-01-01

    Similarly to other studies the present dissertation presupposes that the Single European Market will lead to an increase in transport waste quantities, and energy consumption and consequently to greater environmental pollution. Of central importance here is the concept of ''expletive costs'' introduced in this paper which describes that damage to the natural and human environment which is not compensated. It forms out that the sectors of transport, waste, and energy alone will most probably send the expletive costs of the Single European Market into astronomic dimensions. In view of the interdependencies of these three sectors it seems doubtful whether the economic benefit to be expected from the establishment of the Single European Market can justify the additional environmental damage thus caused.

    Full Text Available Agriculture has always been considerd as one of the important sectors in domestic and international economy .Based on the Central Bank Statistics; agriculture’s share in the Iranian GDP at the constant price of the year 1998 was 13 percent of the GDP in the year 2007. Therefore, studies on the role of agriculture in an economy and its interactions with other economic sectors should be considered with a special attention. This paper aimed at surveying the effects of growth of value-added in agriculture on the value-added of different sectors of industry, services as well as subordinate sectors of transportation, communication and commerce. In this regard, the status of the period between 1967 to 2009 is used. To determine the relationship among the study variables, some econometric techniques such as VAR were used. The results of VAR technique proves that there is a positive relation among the growth of value-added in the agricultural sector with the growth of industrial sector and the growth of sub-sectors of communication, transportation and commerce. Among the mentioned sectors and sub-sectors, the growth of commerce has maximum effect on the agricultural growth. Furthermore, in the short term, the growth variant of trading sector presented the largest share in explaining the variants of the agriculture sector . The growth variant of communication sector is trivial

    As described in the Department of Energy Office of Nuclear Energy's Nuclear Energy R and D Roadmap, nuclear energy can play a significant role in supplying energy for a growing economy while reducing both our dependence on foreign energy supplies and emissions from the burning of fossil fuels. The industrial and transportation sectors are responsible for more than half of the greenhouse gas emissions in the U.S., and imported oil supplies 70% of the energy used in the transportation sector. It is therefore important to examine the various ways nuclear energy can facilitate a transition away from fossil fuels to secure environmentally sustainable production and use of energy in the transportation and manufacturing industry sectors. Imperative 3 of the Nuclear Energy R and D Roadmap, entitled 'Enable a Transition Away from Fossil Fuels by Producing Process Heat for use in the Transportation and Industrial Sectors', addresses this need. This document presents an Implementation Plan for R and D efforts related to this imperative. The expanded use of nuclear energy beyond the electrical grid will contribute significantly to overcoming the three inter-linked energy challenges facing U.S. industry: the rising and volatile prices for premium fossil fuels such as oil and natural gas, dependence on foreign sources for these fuels, and the risks of climate change resulting from carbon emissions. Nuclear energy could be used in the industrial and transportation sectors to: (1) Generate high temperature process heat and electricity to serve industrial needs including the production of chemical feedstocks for use in manufacturing premium fuels and fertilizer products, (2) Produce hydrogen for industrial processes and transportation fuels, and (3) Provide clean water for human consumption by desalination and promote wastewater treatment using low-grade nuclear heat as a useful additional benefit. Opening new avenues for nuclear energy will significantly enhance our nation

    Transportation sectors in developing countries suffer from some diseases that one of them is ever-increasing energy consumption. Integrated National Energy Planning (INEP) in transportation sector is a solution for these countries to alter their suboptimal pattern and rationalize their energy consumption. One of the INEP targets is determining optimal patterns of fuels and transportation technologies to satisfy future demand of freight and passenger transportation at the lowest cost levels. Following the above target, this paper is concerned with the optimal consumption pattern of fuels focusing on vehicle technologies within the next 25 years (up to 2029). Using Energy Flow Optimization Model-ENVironment (EFOM-ENV) model, various steps as designing of 'Reference Energy System (RES)' of the model, data processing and scenario analysis are followed. Based on the modeling results, substitution of urban railroad technologies (subway, LRT and monorail), all of passenger CNG technologies (cars, buses and minibuses), rural railroad freight technologies (electrical, gas oil and LNG freight trains) and finally, CNG and LNG heavy and light trucks with current passenger and freight vehicle technologies are suggested. This scenario will decline fuel consumption by about 14% totally, that the most part of it belongs to gasoline and gas oil (24% and 17%, respectively). Total discounted cost of transportation system will decline from 806.20 to 691.74 billion dollars (14%) during the time horizon.

    2014-01-01

    Full Text Available Recent geographical analyses of global production networks in different economic sectors demonstrate that little attention has been paid to the logistical and transport systems through which networks are fully integrated. This paper on Inditex, a leading firm in the fast fashion sector, addresses this lack of attention and analyses how transport and logistics fit into the production network and provide the firm with one of its most notable competitive advantages. We describe the network of shops and manufacturing, present the principles of the logistical model, and provide details of the procedures applied for the functional and geographical integration of the chain of production of Zara, the best known of the company’s 11 brands. The analysis highlights the growing use of air transport in supplying chains of high-fashion-content products manufactured in distant countries and in the distribution of garments to distant markets. The conclusion of the paper is that logistics and transport strategies must be considered because the geographical configuration of global fashion networks increasingly depends on how rapidly the major fashion retailers are able to meet the needs of time-sensitive customers and the appropriate organisational and logistical strategies they adopt for that purpose.

    The transport sector is currently responsible for about one-fifth of Germany's greenhouse gas emissions. While in other sectors since 1990 partly clear emission reductions have been achieved, are the emissions of traffic during the same period even slightly increased. In his special report the German Council of Environmental Advisors (SRU) points out which strategic course should be set for the change in transport policy. The decarbonisation of the transport sector requires a consistent overall concept. It should be done as soon as possible, a switch to alternative drives. In traffic electromobility is to be accelerated, because of direct electrification the primary energy consumption is kept as low as possible. The extraction and recycling of the raw materials required for electromobility should be made sustainable. In addition, the energy consumption of motorized transport must also be be significantly further reduced, especially by on-board efficiency measures. In addition to technological changes a fundamental change of transport systems and mobility patterns is also necessary. The avoidance and relocation of traffic not only contributes to climate protection, but also to reduce its other environmental and health burdens. In order to promote cost transparency in the transport sector, taxes, levies and subsidies should be consistently aligned with climate, environmental and health policy objectives. For the SRU, this also includes the introduction of a route-dependent car toll. [German] Der Verkehrssektor ist derzeit fuer etwa ein Fuenftel der Treibhausgasemissionen Deutschlands verantwortlich. Waehrend in anderen Sektoren seit 1990 zum Teil deutliche Emissionsminderungen erzielt wurden, sind die Emissionen des Verkehrs im gleichen Zeitraum sogar leicht angestiegen. In seinem Sondergutachten ''Umsteuern erforderlich: Klimaschutz im Verkehrssektor'' zeigt der SRU auf, welche strategischen Weichen fuer die Verkehrswende gestellt werden

    The work activity developed on board is of great importance in our nearby environment, and it has a series of peculiarities that determine the service rendering of sea workers. On the other hand, work at sea is developed on an international basis. Nowadays such work becomes a completely globalised industrial sector in relation to the elements that make up the ship's operation, including manpower. For that reason several relevant international organisations have paid attention to this industrial sector and have adopted a broad regulation on this matter. In the case of the European Union, the Community procedure emphasises enormous interest in providing specific and comprehensive training to seafarers, as well as in regulating working time on board with the aim of minimising the safety problems caused by fatigue. In the present article a schematic presentation of regulations on workers' health and occupational safety protection derived from the European Union, the International Maritime Organisation, and the International Labour Organisation has been done. Also it shows what parts of these regulations are not applicable to the work on board, and it reveals how the workers of fishing and maritime transport sectors are under-protected with regard to the guarantee of their health and occupational safety compared to workers in other sectors.

    Nowadays the labour sector is experiencing an important increase in the application of risk prevention policies. Although these policies are very significant due to their repercussions in the health of workers, we noticed important legal gaps in maritime sector regulations. Frequently sea workers are legally abandoned, by exclusion or omission, at the moment of claiming for the improvement of their working environment and the reduction of the negative consequences derived from this negligence over their safety and health. In the present paper we try to shed some light on this topic by analysing and examining minutely the Spanish applicable risk prevention legislation for this sector. Moreover, the recommendations of the International Maritime Organization are compared with the current application of the law. At the same time, we present some possible solutions to such problems from an objective point of view.

    Previous research has emphasized the need to consider the social dimension featuring organizations in order to maximize organizational efficiency (Rasmussen, 1997). In the road transport sector, previous research has focused on the relationship between human factor, stress, fatigue, and other relevant issues, and professional drivers health and safety (p.e., De Croon et al, 2004). However, research on relevant organizational factors is scarce. This study aims to examine the association between leadership and supportive climate, and employees health and safety. Moreover, the impact of stress (time pressure) was also examined because previous research has stressed its importance. This study used a sample of 486 employees from 35 different Spanish companies pertaining to the road transport sector. Findings showed time pressure to be negatively associated to employees health, job satisfaction and satisfaction with safety. Additionally, leadership was positively associated employees health, job satisfaction and satisfaction with safety. Finally, co-workers and supervisors supportive climate was positively associated with job satisfaction and negatively associated to illness. These findings have relevant practical implications for the competitiveness of road transport companies. (Author) 21 refs.

  11. A policy instruments working paper on reducing CO2 emissions from the transportation sector in Ontario

    1995-11-01

    The cost effectiveness of policy instruments for reducing CO 2 emissions from transportation was studied. Cost effectiveness analyzed the impact of the policy instruments in reducing CO 2 emissions against the costs that were incurred while obtaining CO 2 reductions. The approach to defining sustainable transportation was identified which integrates three different visions of the transportation challenge: (1) changing urban form to reduce the need for transportation, (2) advancing technology to reduce the ecological impact of transportation, and (3) changing prices of transportation so that users pay for the full social and environmental costs of their decisions. The general consensus was that while fuel tax on gasoline for automobiles appeared to be the most cost effective option available, all revenue generating options, (e.g.,parking pricing, reference energy factor-related rebates, full cost road pricing and taxation) rated higher on the cost effectiveness indexes than any of the other policy instruments considered. refs., tabs., figs

    Malaysia's transportation sector accounts for 41% of the country's total energy use. The country is expected to become a net oil importer by the year 2011. To encourage renewable energy development and relieve the country's emerging oil dependence, in 2006 the government mandated blending 5% palm-oil biodiesel in petroleum diesel. Malaysia produced 16 million tonnes of palm oil in 2007, mainly for food use. This paper addresses maximizing bioenergy use from oil-palm to support Malaysia's energy initiative while minimizing greenhouse-gas emissions from land-use change. When converting primary and secondary forests to oil-palm plantations between 270-530 and 120-190 g CO 2 -equivalent per MJ of biodiesel produced, respectively, is released. However, converting degraded lands results in the capture of between 23 and 85 g CO 2 -equivalent per MJ of biodiesel produced. Using various combinations of land types, Malaysia could meet the 5% biodiesel target with a net GHG savings of about 1.03 million tonnes (4.9% of the transportation sector's diesel emissions) when accounting for the emissions savings from the diesel fuel displaced. These findings are used to recommend policies for mitigating GHG emissions impacts from the growth of palm oil use in the transportation sector. - Research highlights: → We modeled greenhouse gas emissions in the production of palm-biodiesel. → Five land types were included to model emissions associated with land-use change. → Land-use change has the biggest impact on the emissions in making palm-biodiesel. → Emissions from fertilizer use and effluent treatment are still significant. → At 5% biodiesel grown on suitable lands Malaysia would obtain an emissions savings.

    The greenhouse effect gases emitted by transport vehicles are mainly carbon dioxide, methane and nitrogen dioxide; CO 2 emissions from transport vehicles (automobiles, aircraft) are growing and their relative importance is growing even more due to lowering of other CO 2 sources. Greenhouse gases from thermal engines are assessed as a function of engine and fuel types. Several solutions are proposed in order to reduce pollutant emissions: road traffic control (road pricing), automobile restricted utilization (speed, access areas, traffic and parking regulation), consumption regulation, collective transports (buses, mini buses), urban organization for pedestrian and bicycle transport, fuel substitution, life style modification tele-commuting, etc

    Full Text Available The globalization process involves the liberalization of the services and the air transportation industry is responsive to this reality. There is a developing tendency for global alliances and strategies in major airline companies. The globalization implies extending service networks in the whole world. Currently we are witnessing lower prices for domestic and foreign airline flights with benefits for the tourists’ business and leisure activities. The last minute offers and early booking prices provide a win-win situation, for the airline companies on one side and for the customers on the other side. The positive online reviews influence people buying decision because customers are more sensitive than ever to the services prices. Under this condition it is very interesting to see the evolution of pricing in the air transportation industry and the implication for the Romanian tourism sector.

  18. Designing a climate change policy for the international maritime transport sector: Market-based measures and technological options for global and regional policy actions

    Miola, A.; Marra, M.; Ciuffo, B.

    2011-01-01

    The international maritime transport sector has a significant abatement potential and some technical improvements that reduce GHG emissions would already be profitable without any policy in place. This paper analyses in-depth the limits and opportunities of policy options currently under consideration at the international level to stimulate the sector to reduce its GHG emissions. In particular, in order for the maritime transport sector to become more environmentally friendly, the flexible nature of international market-based measures and the European Union Emission Trading Scheme provide a definite window of opportunity without placing unnecessary high burden on the sector. However, the development of a regional policy, such as at European level, for the international maritime transport sector faces several obstacles: allocation of emissions, carbon leakage, permit allocation, treatment of the great variety in ship type, size and usage, and transaction cost. Global market-based policies could overcome most of these challenges. This paper provides an in-depth analysis of the policy instruments currently under discussion to reduce the sector's burden on the environment, and focuses on economic theory, legal principles, technological options, and the political framework that together make up the basis of decision-making regarding the international maritime transport sector's climate change policies. - Highlights: → Technologies for a more environmental friendly maritime transport sector and their cost-effectiveness. → How to combine ambitious CO 2 reduction goals with a sector-wide market-based policy. → Permits should be auctioned frequently and small emitters have to be excluded. → Inclusion of shipping in the EU ETS causes carbon leakage, so the policy should aim at expansion.

    Demir, Durmus A.; Mosquera Cuesta, Herman J.

    2000-12-01

    The annihilation of pairs of very weakly interacting particles in the neighborhood of gamma-ray sources is introduced here as a plausible mechanism to overcome the baryon load problem. This way we can explain how these very high energy gamma-ray bursts can be powered at the onset of very energetic events like supernovae (collapsars) explosions or coalescences of binary neutron stars. Our approach uses the weak-scale hidden sector models in which the Higgs sector of the standard model is extended to include a gauge singlet that only interacts with the Higgs particle. These particles would be produced either during the implosion of the red supergiant star core or at the aftermath of a neutron star binary merger. The whole energetics and timescales of the relativistic blast wave, the fireball, are reproduced. (author)

    Keshavarzmohammadian, Azadeh; Henze, Daven K; Milford, Jana B

    2017-06-20

    This study investigates emission impacts of introducing inexpensive and efficient electric vehicles into the US light duty vehicle (LDV) sector. Scenarios are explored using the ANSWER-MARKAL model with a modified version of the Environmental Protection Agency's (EPA) 9-region database. Modified cost and performance projections for LDV technologies are adapted from the National Research Council (2013) optimistic case. Under our optimistic scenario (OPT) we find 15% and 47% adoption of battery electric vehicles (BEVs) in 2030 and 2050, respectively. In contrast, gasoline vehicles (ICEVs) remain dominant through 2050 in the EPA reference case (BAU). Compared to BAU, OPT gives 16% and 36% reductions in LDV greenhouse gas (GHG) emissions for 2030 and 2050, respectively, corresponding to 5% and 9% reductions in economy-wide emissions. Total nitrogen oxides, volatile organic compounds, and SO 2 emissions are similar in the two scenarios due to intersectoral shifts. Moderate, economy-wide GHG fees have little effect on GHG emissions from the LDV sector but are more effective in the electricity sector.

    Highlights: • Integration of carbon capture and sequestration and renewable resource technologies. • A new superstructure-based optimization model to identify the energy supply system. • Model validation via application study of the future transportation sector in Korea. - Abstract: In this study, a new design for a sustainable energy system was developed by integrating two technology frameworks: the renewable resource-based energy supply and the conventional (fossil fuel) resource-based energy production coupled with carbon capture and sequestration. To achieve this goal, a new superstructure-based optimization model was proposed using mixed-integer linear programming to identify the optimal combination of these technologies that minimizes the total daily cost, subject to various practical and logical constraints. The performance of the proposed model was validated via an application study of the future transportation sector in Korea. By considering six different scenarios that combined varying crude oil/natural gas prices and environmental regulation options, the optimal configuration of the energy supply system was identified, and the major cost drivers and their sensitivities were analyzed. It was shown that conventional resource-based energy production was preferred if crude oil and natural gas prices were low, even though environmental regulation was considered. Environmental regulation caused an increase in the total daily cost by an average of 26.4%, mainly due to CO_2 capture cost.

  5. Ergonomic analyses within the French transport and logistics sector: first steps towards a new "act elsewhere" prevention approach.

    Statistics from the French Employee National Health Insurance Fund indicate high accident levels in the transport sector. This study represents initial thinking on a new approach to transport sector prevention based on the assumption that a work situation could be improved by acting on another interconnected work situation. Ergonomic analysis of two connected work situations, involving the road haulage drivers and cross-docking platform employees, was performed to test this assumption. Our results show that drivers are exposed to a number of identified risks, but their multiple tasks raise the question of activity intensification. The conditions, under which the drivers will perform their work and take to the road, are partly determined by the quality and organisation of the platform with which they interact. We make a number of recommendations (e.g. changing handling equipment, re-appraising certain jobs) to improve platform organisation and employee working conditions with the aim of also improving driver conditions. These initial steps in this prevention approach appear promising, but more detailed investigation is required. Copyright © 2013 Elsevier Ltd. All rights reserved.

  6. Long-term optimization of the transport sector to address greenhouse gas reduction targets under rapid growth. Application of an energy system model for Gauteng province, South Africa

    2013-12-11

    The transport sector is seen as one of the key factors for driving future energy consumption and greenhouse gas (GHG) emissions. Especially in developing countries, significant growth in transport demand is expected. Gauteng province, as the economic centre of South Africa and transport hub for the whole of southern Africa, is one emerging urban region that faces rapid growth. However, the province is on its way to playing a leading role for supporting ways to adapt to climate change and mitigate GHG emissions. Conversely, there is a lack of scientific research on the promising measures for GHG mitigation in the transport sector. For the rapidly growing transport sector of the province in particular, research is focused primarily on extending and structuring the road infrastructure. Moreover, it is important that the transport sector is considered as part of the whole energy system, as significant contributions to GHG emissions and the associated costs arise from energy supply, provision and conversion. This research is the first application of an integrated energy system model (i.e. the TIMES-GEECO model) for the optimization of the transport sector of Gauteng. Optimizing energy system models allows finding least-cost measures for various scenarios, by considering dependencies and interlinkages in the energy system as well as environmental constraints. To do so, the transport sector and the energy supply sector had to be incorporated into the model application in terms of the characteristics of a developing urban region, which includes all relevant transport modes, vehicle technologies, fuel options, vehicle-to-grid energy storage, the consideration of road types as well as explicit expansions of the public transport system and income-dependent travel demand modelling. Additionally, GHG mitigation options outside the provincial boundaries were incorporated to allow for mitigation at least cost and to consider regional resource availability. Moreover, in TIMES

    2011-10-11

    A two-part Delphi Survey was given to transportation experts attending the Asilomar Conference on Transportation and Energy in August, 2011. The survey asked respondents about trends in the US transportation sector in 2030. Topics included: alternative vehicles, high speed rail construction, rail freight transportation, average vehicle miles traveled, truck versus passenger car shares, vehicle fuel economy, and biofuels in different modes. The survey consisted of two rounds -- both asked the same set of seven questions. In the first round, respondents were given a short introductory paragraph about the topic and asked to use their own judgment in their responses. In the second round, the respondents were asked the same questions, but were also given results from the first round as guidance. The survey was sponsored by Argonne National Lab (ANL), the National Renewable Energy Lab (NREL), and implemented by University of California at Davis, Institute of Transportation Studies. The survey was part of the larger Transportation Energy Futures (TEF) project run by the Department of Energy, Office of Energy Efficiency and Renewable Energy. Of the 206 invitation letters sent, 94 answered all questions in the first round (105 answered at least one question), and 23 of those answered all questions in the second round. 10 of the 23 second round responses were at a discussion section at Asilomar, while the remaining were online. Means and standard deviations of responses from Round One and Two are given in Table 1 below. One main purpose of Delphi surveys is to reduce the variance in opinions through successive rounds of questioning. As shown in Table 1, the standard deviations of 25 of the 30 individual sub-questions decreased between Round One and Round Two, but the decrease was slight in most cases.

  12. Scenarios for biofuels in the road transport sector - environmental and welfare economic consequences. Synthesis report from the REBECa project

    Frederiksen, P.

    2013-01-15

    The project, Renewable energy in the transport sector using biofuel as energy carrier (REBECa), aimed to investigate the potentials for providing biofuels for the road transport sector based on domestically cultivated bioenergy crops, and to analyse the consequences for air quality, land use, GHG emission and welfare economy. Moreover, a review of international perspectives on sustainability of biofuels was carried out. Different scenarios for the introduction of biofuels were developed - one aiming at 10 % share of biofuels in 2020, and another aiming at 25 % share in 2030. A forecast of the road transport until 2030 was produced and ensuing energy demand modelled. Estimates of the resulting demand for biomass, based on wheat grain, straw and rape, were introduced in agricultural scenarios of production and land use, and the possibilities for responding to the biomass requirements were analysed. Wellto-wheel emissions to air were calculated and impacts on air quality and health hazard investigated. Welfare economic effects corresponding to the well-to-wheel analytical framework were analysed. Results show that changes in air emissions (apart from CO{sub 2}) resulting from substitution of fossil fuel with biofuel were small, due to the general reduction of air emissions owing to EU policy implementation and technological development. The provision of sufficient home-grown bioenergy crops would at some stage influence the production of fodder. The overall results for fossil fuel reductions, CO{sub 2} emissions and the welfare economic costs using rape, wheat grain and straw as bioenergy crops, may point in opposite directions for the different fuels. While the largest gains in fossil fuel saving is related to the Rape Methyl Ester (RME) production chain, the welfare economic benefits show the largest positive results for 2{sup nd} generation biofuel. Results are highly dependent on decisions related to the analysis of co-products, and the prices of oil and wheat

  13. Modeling transitions in the California light-duty vehicles sector to achieve deep reductions in transportation greenhouse gas emissions

    California’s target for reducing economy-wide greenhouse gas (GHG) emissions is 80% below 1990 levels by 2050. We develop transition scenarios for meeting this goal in California’s transportation sector, with focus on light-duty vehicles (LDVs). We explore four questions: (1) what options are available to reduce transportation sector GHG emissions 80% below 1990 levels by 2050; (2) how rapidly would transitions in LDV markets, fuels, and travel behaviors need to occur over the next 40 years; (3) how do intermediate policy goals relate to different transition pathways; (4) how would rates of technological change and market adoption between 2010 and 2050 impact cumulative GHG emissions? We develop four LDV transition scenarios to meet the 80in50 target through a combination of travel demand reduction, fuel economy improvements, and low-carbon fuel supply, subject to restrictions on trajectories of technological change, potential market adoption of new vehicles and fuels, and resource availability. These scenarios exhibit several common themes: electrification of LDVs, rapid improvements in vehicle efficiency, and future fuels with less than half the carbon intensity of current gasoline and diesel. Availability of low-carbon biofuels and the level of travel demand reduction are “swing factors” that influence the degree of LDV electrification required. - Highlights: ► We model change in California LDVs for deep reduction in transportation GHG emissions. ► Reduced travel demand, improved fuel economy, and low-carbon fuels are all needed. ► Transitions must begin soon and occur quickly in order to achieve the 80in50 goal. ► Low-C biofuel supply and travel demand influence the need for rapid LDV electrification. ► Cumulative GHG emissions from LDVs can differ between strategies by up to 40%.

  17. Raising Climate Finance from International Transport Sectors. Identification and Analysis of Governance Structures

    2012-03-15

    Market based instruments (MBIs) for maritime transport have the potential to reduce emissions while at the same time raising funds for climate policies in developing countries. GHG emissions from international aviation and maritime transport accounted for approximately 5% of global anthropogenic emissions in 2005 and are rising rapidly. There is a clear need to address these emissions in order not to undermine policies for mitigating land based emissions. Developing countries need financial support to carry out climate policies, both adaptation and mitigation. The UN Framework Convention on Climate Change (UNFCCC) makes policies by developing countries conditional on climate finance. In the current economic and financial circumstances, there is a need for new sources of finance. The governance of such MBIs should ensure that they are neither an international tax nor require hypothecation of fiscal revenues, while they should provide new and additional finance. MBIs which are in fact an international tax would not be politically feasible, and likewise hypothecation would be opposed by many states. This report finds that an emissions trading scheme (ETS) can satisfy these criteria, provided that: (1) it transfers a share of allowances directly to developing countries in order to ensure there is no net incidence on them; developing countries could auction these allowances in order to raise revenue; (2) it transfers allowances to the Green Climate Fund to support climate policies; auctioning these allowances would provide revenues for the Fund; (3) it transfers allowances to IMO or another organisation in order to finance fuel-efficiency improvements in international transport.

    This PhD thesis is based on the observation that developing countries will not participate in climate policies as long as they perceive them as another constraint on their development. We demonstrate that emission reduction projects realised in DCs under the Kyoto Protocol may have a leverage effect on development by removal of barriers to development. They may also favour the implementation of domestic policies that will attract foreign private investors in projects responding to development priorities of the host country. We show the limits of the Kyoto Protocol concerning the implementation of emission reductions in high inertia sectors (transportation) and the necessity to coordinate climate policies with official development aid flows for the financing of infrastructures in an emerging context of public-private partnership.

    1993-01-01

    The primary objective of this report is to provide estimates of volumes and development costs of known nonassociated gas reserves in selected, potentially important supplier nations, using a standard set of costing algorithms and conventions. Estimates of undeveloped nonassociated gas reserves and the cost of drilling development wells, production equipment, gas processing facilities, and pipeline construction are made at the individual field level. A discounted cash-flow model of production, investment, and expenses is used to estimate the present value cost of developing each field on a per-thousand-cubic-foot (Mcf) basis. These gas resource cost estimates for individual accumulations (that is, fields or groups of fields) then were aggregated into country-specific price-quantity curves. These curves represent the cost of developing and transporting natural gas to an export point suitable for tanker shipments or to a junction with a transmission line. The additional costs of LNG or methanol conversion are not included. A brief summary of the cost of conversion to methanol and transportation to the United States is contained in Appendix D: Implications of Gas Development Costs for Methanol Conversion.

    Forest-derived methane could complement biogas from anaerobic digestion as a transport fuel. The conditions for a systemic transition have been analyzed in this article. The analysis contains three blocks: the vehicle gas development, the policy framework, and commercial projects to produce methane from forest biomass. The results reveal that several conditions for a systemic transition are in place. There is established infrastructure for feedstock supply and biofuels distribution. Infrastructure development is an important albeit not determining factor. Private and public actors have advanced plans for commercial scale plants, technological know-how, and experience from a demonstration plant. However, a major barrier for a systemic transition is the low predictability of Swedish policy instruments. The Swedish government is not free to design policy instruments but must consider compatibility with the EU framework and has changed the energy tax on biofuels several times to avoid overcompensation according to the EU regulation. This has contributed to the low predictability. The interviewees have suggested several concrete policy instruments. However, they have also emphasized that the exact design of the policy instruments is less important than the predictability of the support. - Highlights: • Forest-derived methane may complement biogas from anaerobic digestion in transport. • There are infrastructure and industrial actors ready for a commercial introduction. • The predictability of Swedish policy instruments is perceived as very low. • Compatibility with EU framework constrains Swedish policy instruments design.

  4. Heterogeneity of demand responses in modelling the distributional consequences of tradable carbon permits in the road transport sector

    Personal road transport sector is one of the largest and fastest growing sources of CO 2 emissions. This paper investigates a tradable permit policy for mitigating carbon emissions from personal road transport and discusses various issues of permit allocation. As tradable permits will effectively raise the price of fuel, the policy has important distributional implications. The distribution of burden depends on permit allocation strategies and on the consumer response to an increase in price. The behavioural response may vary among different segments of the population depending on their travel needs, which in turn are contingent upon their income, location of residence and other factors. Consumer Expenditure Survey micro dataset from 1997 to 2002 has been used to econometrically model the possible variation of price elasticity for different socio-economic groups in the USA. Results indicate that the response of gasoline demand to a change in price does depend on income level or location of the household. Distributional impacts of the tradable permit policy are then evaluated using the micro dataset for year 2002. In this regard, different permit allocation schemes are considered in the analysis. Impacts on households owning a vehicle and households with no vehicles have been evaluated as well

    The transportation sector is a complex system. Collecting transportation activity and the associated emissions data is extremely expensive and time-consuming. Grey Relational Analysis provides a viable alternative to overcome data insufficiency and gives insights for decision makers into such a complex system. In this paper, we achieved three major goals: (i) we explored the inter-relationships among transportation development, energy consumption and CO2 emissions for 30 provincial units in China; (ii) we identified the transportation development mode for each individual province; and (iii) we revealed policy implications regarding the sustainable transportation development at the provincial level. We can classify the 30 provinces into eight development modes according to the calculated Grey Relational Grades. Results also indicated that energy consumption has the largest influence on CO2 emission changes. Lastly, sustainable transportation policies were discussed at the province level according to the level of economy, urbanization and transportation energy structure. PMID:29292779

The major findings are that an increased share of EV can reduce...... the socioeconomic cost of the energy system in 2050. However, electricity demand for H2 generation via electrolysis is more flexible than EV charging and the production can therefore, to a larger degree be used to out-balance variable electricity surplus from a high share of wind energy in the power system......, reducing the investments in backup capacity.

    This study presented a comparison approach with multiple source apportionment methods to identify which sectors of emission data have large biases. The source apportionment methods for the comparison approach included both receptor and chemical transport models, which are widely used to quantify the impacts of emission sources on fine particulate matter of less than 2.5 μm in diameter (PM2.5). We used daily chemical component concentration data in the year 2013, including data for water-soluble ions, elements, and carbonaceous species of PM2.5 at 11 sites in the Kinki-Tokai district in Japan in order to apply the Positive Matrix Factorization (PMF) model for the source apportionment. Seven PMF factors of PM2.5 were identified with the temporal and spatial variation patterns and also retained features of the sites. These factors comprised two types of secondary sulfate, road transportation, heavy oil combustion by ships, biomass burning, secondary nitrate, and soil and industrial dust, accounting for 46%, 17%, 7%, 14%, 13%, and 3% of the PM2.5, respectively. The multiple-site data enabled a comprehensive identification of the PM2.5 sources. For the same period, source contributions were estimated by air quality simulations using the Community Multiscale Air Quality model (CMAQ) with the brute-force method (BFM) for four source categories. Both models provided consistent results for the following three of the four source categories: secondary sulfates, road transportation, and heavy oil combustion sources. For these three target categories, the models' agreement was supported by the small differences and high correlations between the CMAQ/BFM- and PMF-estimated source contributions to the concentrations of PM2.5, SO42-, and EC. In contrast, contributions of the biomass burning sources apportioned by CMAQ/BFM were much lower than and little correlated with those captured by the PMF model, indicating large uncertainties in the biomass burning emissions used in the

    Transportation includes sources of greenhouse gas emission contributor in the form of carbon dioxide (CO2). CO2 is one of the air pollutant gases that cause climate change. The source of CO2 emissions at airports comes from road and air transportation. Kualanamu International Airport is one of the public service airports in North Sumatera Province. The purpose of this study is to inventory the emission loads generated by motor vehicles and aircraft and to forecast contributions of CO2 emissions from motor vehicles and aircraft. The research method used is quantitative and qualitative methods. The quantitative method used is to estimate emission loads of motor vehicles based on vehicle volume and emission factors derived from the literature and using the Tier-2 method to calculate the aircraft emission loads. The results for the maximum CO2 concentration were 6,206,789.37 μg/m3 and the minimal CO2 concentration was 4,070,674.84 μg/Nm3. The highest aircraft CO2 emission load is 200,164,424.5 kg/hr (1.75 x 109 ton/year) and the lowest is 38,884,064.5 kg/hr (3.40 x 108 ton/year). Meanwhile, the highest CO2 emission load from motor vehicles was 51,299.25 gr/hr (449,38 ton/year) and the lowest was 38,990.42 gr/hr (341,55 ton/year). CO2 contribution from a motor vehicle is 65% and 5% from aircraft in Kualanamu International Airport.

    An exergy and environmental comparison between the fuel production routes for Brazilian transportation sector, including fossil fuels (natural gas, oil-derived products and hydrogen), biofuels (ethanol and biodiesel) and electricity is performed, and the percentage distribution of exergy destruction in the different units of the processing plants is characterized. An exergoeconomy methodology is developed and applied to properly allocate the renewable and non-renewable exergy costs and CO 2 emission cost among the different products of multiproduct plants. Since Brazilian electricity is consumed in the upstream processing stages of the fuels used in the generation thereof, an iterative calculation is used. The electricity mix comprises thermal (coal, natural gas and oil-fired), nuclear, wind and hydroelectric power plants, as well as bagasse-fired mills, which, besides exporting surplus electricity, also produce sugar and bioethanol. Oil and natural gas-derived fuels production and biodiesel fatty acid methyl-esters (FAME) derived from palm oil are also analyzed. It was found that in spite of the highest total unit exergy costs correspond to the production of biofuels and electricity, the ratio between the renewable to non-renewable invested exergy (cR/cNR) for those fuels is 2.69 for biodiesel, 4.39 for electricity, and 15.96 for ethanol, whereas for fossil fuels is almost negligible. - Highlights: • Total and non-renewable exergy costs of Brazilian transportation fuels are evaluated. • Specific CO 2 emissions in the production of Brazilian transportation fuels are determined. • Representative production routes for fossil fuels, biofuels and electricity are reviewed. • Exergoeconomy is used to distribute costs and emissions in multiproduct processes

    Full Text Available The road passenger transport is responsible for a large share of energy consumption and pollutants emission in Europe. Efforts have been made in the definition of new policies to reduce the environmental impacts of this sector. However, an integrated and consistent assessment of the most promising policies is required, using specific European indicators. For that matter, a life-cycle analysis was applied to the road passenger transport, for the European Union with 27 countries (EU27 in 2010, following a basket-of-products methodology and considering three main stages: production, use, and end-of-life of vehicles. Simapro 8 software was used, along with Ecoinvent 3 database and the impact assessment method International Reference Life Cycle Data System (ILCD 2011 Midpoint+. Changes in vehicle production processes, vehicle constitution, and energy sources for vehicle propulsion were analyzed. The policies resulting in a decrease in all impact categories are the use of smaller or lightweight vehicles by positively influencing use, production, and end-of-life of vehicles. The use of more recent vehicles technology or diesel vehicles show substantial reductions in, respectively, five and eight impact categories (out of 15, justifying their adoption in the European fleet. Generally, the most notorious policies compared to the actual transport paradigm, like compressed natural gas (CNG, biofuels, or electric vehicles use, show the greatest reduction in climate change (up to 46% but also a very significant rise of impacts in the categories that in the conventional basket-of-products already resulted in the worst indicators after normalization.

    2009-01-01

    In this paper, we use an energy-economy-environment computable general equilibrium (CGE) model of the Scottish economy to examine the impacts of an exogenous increase in energy augmenting technological progress in the domestic commercial Transport sector on the supply and use of energy. We focus our analysis on Scottish refined oil, as the main type of energy input used in commercial transport activity. We find that a 5% increase in energy efficiency in the commercial Transport sector leads to rebound effects in the use of oil-based energy commodities in all time periods, in the target sector and at the economy-wide level. However, our results also suggest that such an efficiency improvement may cause a contraction in capacity in the Scottish refined oil supply sector. This 'disinvestment effect' acts as a constraint on the size of rebound effects. However, the magnitude of rebound effects and presence of the disinvestment effect in the simulations conducted here are sensitive to the specification of key elasticities of substitution in the nested production function for the target sector, particularly the substitutability of energy for non-energy intermediate inputs to production.

  15. What is a fair CO2 tax increase? On fair emission reductions in the transport sector

    Hammar, Henrik; Jagers, Sverker C.

    2007-01-01

    We examine how individual preferences for fair reductions of carbon dioxide (CO 2 ) emissions affect the support for increases in the CO 2 tax on gasoline and diesel. We assume that people not only care about their own material welfare, but also have preferences for fairness in policy design, and we explore the implications using original data from a mail questionnaire sent to a representative sample of the Swedish population. The main result is that fairness in policy design does matter. Those respondents who adhere to a fairness principle tend to be relatively more positive to increases in the CO 2 tax. One possible explanation for this result is that there is a relatively high degree of reciprocity regarding the origin of emissions and the fairness regarding who should bear the burden of CO 2 reductions. Via a split sample analysis, we also find that the relative importance of fairness principles is dependent upon whether one uses a car often or not. This sheds light on the potential goal conflict between the importance of fairness principles and self-interest in the form of a need for private car transportation. (author)

    2000-07-01

    This report presents a critical analysis of the health and safety issues surrounding competing transport fuel options, including those for possible future fuel-cell powered vehicles. The fuels considered in this report are gasoline (unleaded and reformulated), diesel, hydrogen (H{sub 2}), methanol, natural gas and liquefied petroleum gas (LPG). The analysis presented here is based on available information in peer-reviewed, published papers and other sources such as government department or research laboratory reports and websites. An overall evaluation of the fuels in terms of their toxicity and health effects, environmental fate, and fire and explosion safety aspects is presented. The report is based on current knowledge and makes no assumptions as to how fuels may change in the future if they are to be used in fuel-cell vehicles. The report identifies the hazards of the fuels but does not estimate the risks likely to be associated with their eventual use in fuel-cell vehicles. The focus is on the fuels themselves and not their exhaust or reaction products. sNo assessment has been made of the environmental effects data for the fuels. Broad environmental considerations such as ozone forming potential and also global warming are not considered. Basic information on environmental fate is included to provide an understanding of migratory pathways, environmental compartmentalisation and potential routes of human exposure. Other factors such as economics, government incentives or disincentives and public attitudes may have a bearing on which of the fuels are considered most appropriate for future fuel-cell vehicles; these factors are not considered in any detail in this report.

    Over the past year, several modifications have been made to the NEMS Transportation Model, incorporating greater levels of detail and analysis in modules previously represented in the aggregate or under a profusion of simplifying assumptions. This document is intended to amend those sections of the Model Documentation Report (MDR) which describe these superseded modules. Significant changes have been implemented in the LDV Fuel Economy Model, the Alternative Fuel Vehicle Model, the LDV Fleet Module, and the Highway Freight Model. The relevant sections of the MDR have been extracted from the original document, amended, and are presented in the following pages. A brief summary of the modifications follows: In the Fuel Economy Model, modifications have been made which permit the user to employ more optimistic assumptions about the commercial viability and impact of selected technological improvements. This model also explicitly calculates the fuel economy of an array of alternative fuel vehicles (AFV`s) which are subsequently used in the estimation of vehicle sales. In the Alternative Fuel Vehicle Model, the results of the Fuel Economy Model have been incorporated, and the program flows have been modified to reflect that fact. In the Light Duty Vehicle Fleet Module, the sales of vehicles to fleets of various size are endogenously calculated in order to provide a more detailed estimate of the impacts of EPACT legislation on the sales of AFV`s to fleets. In the Highway Freight Model, the previous aggregate estimation has been replaced by a detailed Freight Truck Stock Model, where travel patterns, efficiencies, and energy intensities are estimated by industrial grouping. Several appendices are provided at the end of this document, containing data tables and supplementary descriptions of the model development process which are not integral to an understanding of the overall model structure.

    The Metropolitan Area of São Paulo (MASP) is impacted by the emission of 7 million vehicles, being 85% light-duty vehicles (LDV), 3% heavy-duty diesel vehicles (HDV)s, and 12% motorcycles. About 55% of LDVs burn a mixture of 78% gasoline and 22% ethanol (gasohol), 4% use hydrous ethanol (95% ethanol and 5% water), 38% are flex-fuel vehicles that are capable of burning both gasohol and hydrous ethanol and 3% use diesel (diesel + 5% bio-diesel). The owners of the flex-fuel vehicles decide to use ethanol or gasohol depending on the market price of the fuel. Many environmental programs were implemented to reduce the emissions by the LDV and HDV traffic; the contribution from the industrial sector has been decreasing as the industries have moved away from MASP, due to the high taxes applied to the productive sector. Due to the large contribution of the transport sector to CO2, its contribution is important in a regional scale. The total emission is estimated in 15327 million tons per year of CO2eq (60% by LDV, 38% HDV and 2% motorcycles). Measurements of CO2 performed with a Picarro monitor based on WS-CRDS (wavelength-scanned cavity ringdown spectroscopy) for the years 2012-2013 were performed. The sampling site was on the University of Sao Paulo campus (22o34´S, 46o44´W), situated in the west area of the city, surrounded by important traffic roads. The average data showed two peaks, one in the morning and the other in the afternoon, both associated with the traffic. Correlation analysis was performed between the concentrations and the number of vehicles, as a proxy for the temporal variation of the CO2 emission. The highest concentration was 430 ppm at 8:00am, associated to the morning peak hour of vehicles and the stable condition of the atmosphere. The average concentration was 406 ±12 ppm, considering all measured data. According to official inventories from the Environmental Agency (CETESB), the emission of CO2 has increased 39% from 1990 to 2008, associated

    In July, 2003, FiFo Koeln (Cologne Centre for Public Economics) was mandated by the German Federal Environmental Agency (UBA) with the examination of the UFOPLAN scheme 'Emissions Trading System for the Transport Sector - Development of a possible Trading Approach'. The main task of this study was the development of a concrete emissions trading approach for the transport sector, which triggers off a compulsory holding of emissions certificates at the beginning of the energy supply chain (upstream approach). The main focus was rather put on the practical options of the implementation of an upstream approach in the transport sector and its specific problems. The transaction costs of a trading system in the transport sector had to be kept at a minimum level. The upsteam approach discussed in his study seems to be more adequate to include further carbon dioxide emissions of other sectors than the EU downstream model. This can mainly be attributed to the amount and nature of the respective transaction costs. In Germany allocative failure in fuel taxation between diesel and petrol can be diminished regardless of the prices for CO{sub 2}. Emissions trading therefore leads to structural changes. An upstream approach has only indirect effects on the motorcar industry and refiners. Therefore, technical CO{sub 2} reduction can primarily be realised via an increased consumer demand for ore fuel-efficient vehicles, new propulsion technology or alternative fuels based on renewable energies. In the case of an open trading system the amount of transport emissions was estimated that actually could be reduced to be relatively small. The authors of the contribution under consideration are not convinced that the full potential of existing adaptation options in the transport sector can be tapped by an open emissions trading. The transport sector will cope with additional CO{sub 2} costs without tapping the potential of relatively cheap adaptation options. Also at closed

    Economic impact assessments of air pollution-related health effects from a sectoral perspective in China is still deficient. This study evaluates the PM 2.5 pollution-related health impacts of the road transport sector on China's economy at both national and provincial levels in 2030 under various air mitigation technologies scenarios. Health impacts are estimated using an integrated approach that combines the Greenhouse Gas and Air Pollution Interactions and Synergies (GAINS) model, a computable general equilibrium (CGE) model and a health model. Results show that at a national level, the road transport sector leads to 163.64 thousand deaths per year, increases the per capita risk of morbidity by 0.37% and accounts for 1.43 billion Yuan in health care expenditures. We estimate 442.90 billion Yuan of the value of statistical life loss and 2.09 h/capita of work time loss in 2015. Without additional control measures, air pollution related to the transport sector will cause 177.50 thousand deaths in 2030, a 0.40% per capita increase in the risk of morbidity, accounting for 4.12 billion Yuan in health care expenditures, 737.15 billion Yuan of statistical life loss and 2.23 h/capita of work time loss. Based on our model, implementing the most strict control strategy scenario would decrease mortality by 42.14%, morbidity risk by 42.14%, health care expenditures by 41.94%, statistical life loss by 26.22% and hours of work time loss by 42.65%, comparing with the no control measure scenario. In addition, PM 2.5 pollution from the road transport sector will cause 0.68% GDP loss in 2030. At a provincial level, GDP losses in 14 out of 30 provinces far exceed the national rate. Henan (1.20%), Sichuan (1.07%), Chongqing (0.99%), Hubei (0.94%), and Shandong (0.90%) would experience the highest GDP loss in 2030. Implementing control strategies to reduce PM 2.5 pollution in the road transport sector could bring positive benefits in half of the Chinese provinces especially in

  1. GHG Emissions and Costs of Developing Biomass Energy in Malaysia: Implications on Energy Security in the Transportation and Electricity Sector

    Malaysia's transportation sector accounts for 48% of the country's total energy use. The country is expected to become a net oil importer by the year 2011. To encourage renewable energy development and relieve the country's emerging oil dependence, in 2006 the government mandated blending 5% palm-oil biodiesel in petroleum diesel. Malaysia produced 16 million tonnes of palm oil in 2007, mainly for food use. This study addresses maximizing bioenergy use from oil-palm to support Malaysia's energy initiative while minimizing greenhouse gas emissions from land use change. When converting primary and secondary forests to oil-palm plantations between 270 - 530 g and 120 -190 g CO2 equivalent (CO2-eq) per MJ of biodiesel produced, respectively, is released. However, converting degraded lands results in the capture of between 23 to 85 g CO2-eq per MJ of biodiesel produced. Using various combinations of land types, Malaysia could meet the 5% biodiesel target with a net GHG savings of about 1.03 million tonnes (4.9% of the transportation sector's diesel emissions) when accounting for the emissions savings from the diesel fuel displaced. Fossil fuels contributed about 93% to Malaysia's electricity generation mix and emit about 65 million tonnes (Mt) or 36% of the country's 2010 Greenhouse Gas (GHG) emissions. The government has set a target to install 330 MW biomass electricity by 2015, which is hoped to avoid 1.3 Mt of GHG emissions annually. The availability of seven types of biomass residues in Peninsular Malaysia is estimated based on residues-to-product ratio, recoverability and accessibility factor and other competing uses. It was found that there are approximately 12.2 Mt/yr of residues. Oil-palm residues contribute about 77% to the total availability with rice and forestry residues at 17%. Electricity from biomass can be produced via direct combustion in dedicated power plants or co-fired with coal. The co-firing of the residues at four existing coal plants in

    The introduction of carbon tax is expected to mitigate GHG emissions cost-effectively. With this expectation identifying the impacts of carbon tax on energy demand and GHG emission reductions is an interesting issue. One of the basic methods of estimating these impacts is using the price elasticity. There are, however, some unanswered questions regarding the use of price elasticity. First, which elasticity estimates are appropriate to measure the impacts of carbon tax on energy demand? The existing estimates are estimated in the presence of a substitute. To assess the impact of carbon tax could we use these estimates? Second, how can we compromise the differences among the existing estimates depending on estimation methods and specifications? For example, how can we accommodate the difference in the estimates from the regional panel specification and the aggregate specification? This paper tries to answer these questions with the price elasticity of gasoline demand. With an appropriate price elasticity, we show how much gasoline consumption and GHG emissions are reduced by carbon tax for different scenarios of carbon tax rate. - Research highlights: →We offer an appropriate estimate for evaluating the effects of carbon tax. →We estimate the price elasticity of gasoline with instrument variables. →We measure the tax effects on CO 2 emissions from transportation sector.

    Subsidizing energy-efficient technologies is considered by energy and environmental organizations to be one of the most effective policies for decreasing energy consumption. In the transportation sector such policies are becoming ever more popular, and have been implemented in a considerable number of countries in recent years. Because these policies promote energy-efficient cars with lower usage costs, they may rebound and increase the distances traveled by households that have switched to energy-efficient cars. From an econometric perspective, a subsidization policy can be used as a valid instrument to identify the households’ choice of energy efficiency levels of the cars they own. This identification, in turn, can be utilized to account for endogeneity in the estimation of a rebound effect. The present study uses a natural experiment setting of such a policy implemented in Israel in 2009. The empirical results indicate a fairly large average rebound effect of 40%. The results also indicate that while the policy indeed encouraged the purchase of energy-efficient cars, households that bought a new or used car during the surveyed period did not generate a rebound effect of a different magnitude compared with other households that did not. We discuss the implications of our findings. - Highlights: •Subsidizing energy-efficient cars has become a popular policy in many countries. •We are unaware of studies identifying rebound via cars’ subsidization policy. •We explored a rebound in light of such a policy in Israel. •Household expenditure survey data, fuel prices and car characteristics were employed. •We found an average rebound effect of 40%.

    Full Text Available Many countries are attempting to reduce energy consumption and CO2 emissions while increasing the productivity and efficiency of their industries. An undesirable-output-oriented data envelopment analysis (DEA model with slacks-based measure (SBM was used to evaluate the changes in the environmental efficiency of the transportation sector in 30 Chinese provinces (municipalities and autonomous regions between 2003 and 2012. The potential for decreasing CO2 emissions and energy saving was also assessed. Transportation was found to be inefficient in most of the provinces and the average environmental efficiency was low (0.45. The overall average efficiency reached a maximum in 2005 and continually decreased until a minimum was reached in 2009; since then, it has increased. In general, transportation is more efficient in eastern than in central or western China. A sensitivity analysis was also carried out on the input and output indicators. Based on these findings, some policies are proposed to improve the environmental efficiency of the transportation sector in China.

In that sense, will be shown, first, the current scenario of Peruvian energy, with emphasis on the transport sector, soon after, will be analyzed the availability and potential of NVG and ethanol to replace the gasoline. This study is justified because in Peru's main energy commercially available is natural gas and has excellent conditions for the production of ethanol. The government intends to replace fossil fuels and through some laws and projects are beginning to encourage market development of alternative fuels that could bring economic and environmental benefits to society.

    The title study directly builds on the work previously completed under the EU Transport GHG: Routes to 2050 project. This new work (dubbed EU Transport GHG: Routes to 2050 II) started in January 2011 and was completed in March 2012. The outputs from this new project help to support the Commission in prioritising and developing their strategy for reducing GHG emissions from the transport sector. CE Delft successfully organised the stakeholder engagement as well as the in-depth research on several topics: greenhouse gas (GHG) emissions from vehicle production and infrastructure development, CO2 reduction costs, co-benefits of GHG policies and knock-on consequences of such policies. Also alternative economic development paths were investigated, such as paths that could be less transport intensive, but still deliver increasing levels of prosperity.

    Full Text Available Abstract Background Workplace violence (WPV is an occupational health hazard in both low and high income countries. To design WPV prevention programs, prior knowledge and understanding of conditions in the targeted population are essential. This study explores and describes the views of drivers and conductors on the causes of WPV and ways of preventing it in the road passenger transport sector in Maputo City, Mozambique. Methods The design was qualitative. Participants were purposefully selected from among transport workers identified as victims of WPV in an earlier quantitative study, and with six or more years of experience in the transport sector. Data were collected in semi-structured interviews. Seven open questions covered individual views on causes of WPV and its prevention, based on the interviewees' experiences of violence while on duty. Thirty-two transport professionals were interviewed. The data were analyzed by means of qualitative content analysis. Results The triggers and causes of violence included fare evasion, disputes over revenue owing to owners, alcohol abuse, overcrowded vehicles, and unfair competition for passengers. Failures to meet passenger expectations, e.g. by-passing parts of a bus route or missing stops, were also important. There was disrespect on the part of transport workers, e.g. being rude to passengers and jumping of queues at taxi ranks, and there were also robberies. Proposals for prevention included: training for workers on conflict resolution, and for employers on passenger-transport administration; and, promoting learning among passengers and workers on how to behave when traveling collectively. Regarding control and supervision, there were expressed needs for the recording of mileage, and for the sanctioning of workers who transgress queuing rules at taxi ranks. The police or supervisors should prevent drunken passengers from getting into vehicles, and drivers should refuse to go to dangerous, secluded

    The prospective future adoption of hydrogen to power the road transportation sector could greatly improve tropospheric air quality but also raises the question whether the adoption would have adverse effects on stratospheric ozone. The possibility of these undesirable impacts must be fully evaluated to guide future policy decisions. Here we evaluate the possible impact of a future (2050) H2-based road transportation sector on stratospheric composition and chemistry, especially on stratospheric ozone, with the MOZART chemical transport model. Since future growth is highly uncertain we evaluate the impact for two world evolution scenarios, one based on a high emitting scenario (IPCC A1FI) and the other on a low emitting scenario (IPCC B1), as well as two technological options: H2 fuel cells and H2 internal combustion engines. We assume a H2 leakage rate of 2.5% and a complete market penetration of H2 vehicles in 2050. The model simulations show that a H2-based road transportation sector would reduce stratospheric ozone concentrations as a result of perturbed catalytic ozone destruction cycles. The magnitude of the impact depends on which growth scenario the world evolves and which H2 technology option is applied. For the same world evolution scenario, stratospheric ozone decreases more in the H2 fuel cell scenarios than in the H2 internal combustion engine scenarios because of the NOx emissions in the latter case. If the same technological option is applied, the impact is larger in the A1FI emission scenario. The largest impact, a 0.54% decrease in annual average global mean stratospheric column ozone, is found with a H2 fuel cell type road transportation sector in the A1FI scenario; whereas the smallest impact, a 0.04% increase in stratospheric ozone, is found with applications of H2 internal combustion engine vehicles in the B1 scenario. The impacts of the other two scenarios fall between the above two bounding scenarios. However, the magnitude of these changes is

    Full Text Available This paper focuses on how fragmentation in public administration has become a major institutional constraint on CO2 emission mitigation policies in Thailand, particularly for energy policy in the transportation sector. Most of our data are narratives and descriptions derived from in-depth interviews with various governmental agencies and academics. It was found that in practice, the environmental policy link between separated sectors continues to be weak because of the lack of appropriate institutional structure for integration. We conclude that the institutions tend to be independent, fragmented, and working on relatively narrow mandates. The closed decision-making processes and the organizational structures strongly bias the different administrative units towards their respective interests.

    Persistent organic pollutants (POPs) are toxic substances and so harmful for human health. Mitigation of these emissions are internationally addressed by the Convention on Long-range Transboundary Air Pollution and by the Stockholm Convention. A global insight on POPs emissions evolution is essential since they can be transported long distances, they bio-accumulate and damage the environment. The Emission Database for Global Atmospheric Research (EDGARv4) is currently updated with POPs. We have estimated the global emissions of Polychlorinated biphenyls (PCBs), Polychlorinated dibenzo-p-dioxins (PCDDs), Polychlorinated dibenzofurans (PCDFs), Polycyclic aromatic hydrocarbons (PAHs) (benzo[a]pyrene (BaP), benzo[b]fluoranthene (BbF), benzo[k]fluoranthene (BkF), Indeno[1,2,3-cd]pyrene (IcdP)) and Hexachlorobenzene (HCB) from fuel combustion in the power generation, residential and transport sectors. This emissions inventory has been developed by using as input to the EDGAR technology-based emissions calculation algorithm the fossil fuel consumption data from International Energy Agency (2014) and the emission factors from EMEP/EEA (2013). We provide a complete emission time series for the period 1970-2010 and discuss the trends. A comprehensive analysis of the contribution of East Asia region to the total global will be provided for each substance of the POPs group. An example is presented in Figure 1 for BaP emissions from residential sector; with emissions mainly from China, the East Asia region has a great share (32%) in the total global. We distributed the POPs emissions on gridmaps of 0.1°x0.1° resolution. Areas with high emissions in East Asia will be presented and discussed; Figure 2 shows the hot-spots in East Asia for BaP emissions from the residential sector. These emission gridmaps, used as input for the chemical transport models, contribute to the improvement of impact evaluation, which is a key element in measuring the effectiveness of mitigation

    Full Text Available Summary: The objectives of this study were to assess the current status of HIV-related knowledge, attitudes, and behavior (KAB of employees in the private transport sector in Namibia and to compare companies with established HIV workplace program (WPPs with those that have recently initiated the implementation of such programs. The study was designed as a cross-sectional questionnaire-based survey. Between January and March 2011, the survey was conducted in the Namibian truck transport sector in six companies of different sizes. The participants were selected randomly from the workforce. Data collection was based on a KAB questionnaire.The range of correct answers to the survey concerning the knowledge of HIV transmission was 67–95%. Twenty percent of the employees had never been tested for HIV. Additionally, risky sexual behaviors were quite prevalent and included having multiple concurrent partners and the use of sex for incentives. This study revealed that drivers and laborers were especially at risk for such behaviors. The employees of companies with established WPPs were tested for HIV more often than those of companies with new WPPs; however, aside from this difference, only minor differences were observed between the two groups. The findings of this study highlight the need for on-going HIV information and prevention campaigns that focus on the special needs of mobile and low-income workers. WPPs should be tailored accordingly and shift their focus to more practical approaches, such as voluntary counseling and testing (VCT, to increase their effectiveness.

    Full Text Available Vehicles burning fossil fuel emit a number of substances that change the composition and chemistry of the atmosphere, and contribute to global air and water pollution and climate change. For example, nitrogen oxides and volatile organic compounds (VOCs emitted as byproducts of fossil fuel combustion are key precursors to ground-level ozone and aerosol formation. In addition, on-road vehicles are major CO2 emitters. In order to tackle these problems, molecular hydrogen (H2 has been proposed as an energy carrier to substitute for fossil fuels in the future. However, before implementing any such strategy it is crucial to evaluate its potential impacts on air quality and climate. Here, we evaluate the impact of a future (2050 H2-based road transportation sector on tropospheric chemistry and air quality for several possible growth and technology adoption scenarios. The growth scenarios are based on the high and low emissions Intergovernmental Panel on Climate Change Special Report on Emissions Scenarios, A1FI and B1, respectively. The technological adoption scenarios include H2 fuel cell and H2 internal combustion engine options. The impacts are evaluated with the Community Atmospheric Model Chemistry global chemistry transport model (CAM-Chem. Higher resolution simulations focusing on the contiguous United States are also carried out with the Community Multiscale Air Quality Modeling System (CMAQ regional chemistry transport model. For all scenarios future air quality improves with the adoption of a H2-based road transportation sector; however, the magnitude and type of improvement depend on the scenario. Model results show that the adoption of H2 fuel cells would decrease tropospheric burdens of ozone (7%, CO (14%, NOx (16%, soot (17%, sulfate aerosol (4%, and ammonium nitrate aerosol (12% in the A1FI scenario, and would decrease those of ozone (5%, CO (4%, NOx (11%, soot (7%, sulfate aerosol (4%, and ammonium nitrate aerosol (9% in the B1 scenario

    Emissions from the transportation sector are rapidly changing worldwide; however, the interplay of such emission changes in the face of climate change are not as well understood. This two-part study examines the impact of projected emissions from the U.S. transportation sector (Part I) on ambient air quality in the face of climate change (Part II). In Part I of this study, we describe the methodology and results of a novel Technology Driver Model (see graphical abstract) that includes 1) transportation emission projections (including on-road vehicles, non-road engines, aircraft, rail, and ship) derived from a dynamic technology model that accounts for various technology and policy options under an IPCC emission scenario, and 2) the configuration/evaluation of a dynamically downscaled Weather Research and Forecasting/Community Multiscale Air Quality modeling system. By 2046-2050, the annual domain-average transportation emissions of carbon monoxide (CO), nitrogen oxides (NO x ), volatile organic compounds (VOCs), ammonia (NH 3 ), and sulfur dioxide (SO 2 ) are projected to decrease over the continental U.S. The decreases in gaseous emissions are mainly due to reduced emissions from on-road vehicles and non-road engines, which exhibit spatial and seasonal variations across the U.S. Although particulate matter (PM) emissions widely decrease, some areas in the U.S. experience relatively large increases due to increases in ship emissions. The on-road vehicle emissions dominate the emission changes for CO, NO x , VOC, and NH 3 , while emissions from both the on-road and non-road modes have strong contributions to PM and SO 2 emission changes. The evaluation of the baseline 2005 WRF simulation indicates that annual biases are close to or within the acceptable criteria for meteorological performance in the literature, and there is an overall good agreement in the 2005 CMAQ simulations of chemical variables against both surface and satellite observations.

    The high growth of human activity potentially increases the number of vehicles and the use of fossil fuels that contribute the increase of CO2 emissions in atmosphere. Controlling CO2 emission that causes greenhouse effect becomes the main agenda of Indonesian Government. The first step control CO2 emissions is by measuring the level of CO2 emissions, especially CO2 emissions from fossil fuel consumption in the transport sector. This research aims to assess the level of CO2 emissions from transportation sector on the main roads in the city centre of Pemalang both in weekdays and weekend days. The methods applied to calculate CO2 emissions using Intergovernmental Panel on Climate Change (IPCC) 2006 method. For this, a survey on the number of vehicles passing through the main roads using hand tally counter is firstly done. The results, CO2 emissions in working day, i.e. 49,006.95 tons/year compared to weekend i.e. 38,865.50 tons/year.

    The modified Renewable Fuel Standard (RFS2) prescribes a volume of biofuels to be used in the United States transportation sector each year through 2022. As the dominant component of the transportation sector, we consider the feasibility of the light-duty vehicle (LDV) parc to provide enough demand for biofuels to satisfy RFS2. Sensitivity studies show that the fuel price differential between gasoline and ethanol blendstocks, such as E85, is the principal factor in LDV biofuel consumption. The numbers of flex fuel vehicles and biofuel refueling stations will grow given a favorable price differential. However, unless the feedstock price differential becomes extreme (biomass prices below $100 per dry ton and oil prices above $215 per barrel), which deviates from historical price trends, LDV parc biofuel consumption will fall short of the RFS2 mandate without an enforcement mechanism. Additionally, such commodity prices might increase biofuel consumption in the short-term, but discourage use of biofuels in the long-term as other technologies that do not rely on any gasoline blendstock may be preferable. Finally, the RFS2 program goals of reducing fossil fuel consumption and transportation greenhouse gas emissions could be achieved through other pathways, such as notable improvements in conventional vehicle efficiency. - Author-Highlights: • At current commodity prices, the LDV fleet will not use enough biofuel to meet RFS2. • RFS2 can be met through the promotion of flex-fuel vehicles and their use of E85 fuel. • The gasoline-E85 price premium is the key factor in encouraging biofuel consumption. • RFS2 is satisfied at extreme oil prices (at least $215/barrel). • This oil price encourages biofuel use in the RFS2 timeframe, but not in the long run

  11. Torus sector handling system

    1981-01-01

    A remote handling system is proposed for moving a torus sector of the accelerator from under the cryostat to a point where it can be handled by a crane and for the reverse process for a new sector. Equipment recommendations are presented, as well as possible alignment schemes. Some general comments about future remote-handling methods and the present capabilities of existing systems will also be included. The specific task to be addressed is the removal and replacement of a 425 to 450 ton torus sector. This requires a horizontal movement of approx. 10 m from a normal operating position to a point where its further transport can be accomplished by more conventional means (crane or floor transporter). The same horizontal movement is required for reinstallation, but a positional tolerance of 2 cm is required to allow reasonable fit-up for the vacuum seal from the radial frames to the torus sector. Since the sectors are not only heavy but rather tall and narrow, the transport system must provide a safe, stable, and repeatable method fo sector movement. This limited study indicates that the LAMPF-based method of transporting torus sectors offers a proven method of moving heavy items. In addition, the present state of the art in remote equipment is adequate for FED maintenance

    In this work the main objective is to analyze energy consumption and CO{sub 2} emissions of biohydrogen for use in the transportation sector in Portugal. A life cycle assessment will be performed in order to evaluate bio-hydrogen pathways, having biodiesel and conventional fossil diesel as reference. The pathways were production of feedstock, pre-treatment, treatment, compression, distribution and applications. For the well-to-tank analysis the SimaPro 7.1 software and excel tools are used. This study includes not only a well-to-tank analysis but also a tank-to-wheel analysis (using ADVISOR software) estimating hydrogen consumption and electricity consumption of a fuel cell hybrid and a plug-in hybrid. Several bio-hydrogen feedstocks to produce hydrogen through fermentation processes will be considered: potato peels. (orig.)

    The substitution process resultant of the competition between two opponents fighting for the same resource or market is pointed out through a dynamic model derived from biomathematics. A brief description of the origin of the method based on coupled non-linear differential equations (NLDE) is presented. Numerical adherence of the proposed model to explain several substitution phenomena which have occurred in the past is examined. The proposed method is particularly suitable for prospective analysis and scenarios assessment. In this sense, two applications of the model to prospect the dynamic substitution process in the Brazilian case are done: firstly, the development of the urban gas pipeline system in substituting for the bottled LPG in the dwelling sector and, secondly, the substitution of the urban Diesel transportation fleet by compressed natural gas (CNG) buses

    The objectives of this study were to assess the current status of HIV-related knowledge, attitudes, and behavior (KAB) of employees in the private transport sector in Namibia and to compare companies with established HIV workplace program (WPPs) with those that have recently initiated the implementation of such programs. The study was designed as a cross-sectional questionnaire-based survey. Between January and March 2011, the survey was conducted in the Namibian truck transport sector in six companies of different sizes. The participants were selected randomly from the workforce. Data collection was based on a KAB questionnaire. The range of correct answers to the survey concerning the knowledge of HIV transmission was 67-95%. Twenty percent of the employees had never been tested for HIV. Additionally, risky sexual behaviors were quite prevalent and included having multiple concurrent partners and the use of sex for incentives. This study revealed that drivers and laborers were especially at risk for such behaviors. The employees of companies with established WPPs were tested for HIV more often than those of companies with new WPPs; however, aside from this difference, only minor differences were observed between the two groups. The findings of this study highlight the need for on-going HIV information and prevention campaigns that focus on the special needs of mobile and low-income workers. WPPs should be tailored accordingly and shift their focus to more practical approaches, such as voluntary counseling and testing (VCT), to increase their effectiveness.

    2017-07-01

    Full Text Available As of June 2017, 150 countries have ratified the Paris Climate Agreement. This agreement calls for, among other things, strong reductions in CO2 emissions by 2030 and beyond. This paper reviews the Nationally Determined Contribution (NDCs plans of six Association of Southeast Asian Nations (ASEAN countries and compares their current and projected future CO2 levels across sectors, and their stated targets in the context of their economic and demographic situations. This comparison reveals wide variations in the types of targets, with the “ambition” level changing as the perspective changes from total CO2 to CO2/capita and per unit gross domestic product (GDP. We also review national plans as stated in NDCs and find that while there are many types of policies listed, few are quantified and no attempts are made to score individual or groups of policies for their likelihood in achieving stated targets. We conclude that more analysis is needed to better understand the possible impacts of current policies and plans on CO2 emissions, and whether current plans are adequate to hit targets. Considerations on better aligning targets are also provided.

  19. Electricity and gas market design to supply the German transport sector with hydrogen; Strom- und Gasmarktdesign zur Versorgung des deutschen Strassenverkehrs mit Wasserstoff

    2015-07-01

    The German government has set targets to reduce greenhouse gas emissions by 40% by 2020, 55% by 2030, 70% by 2040 and 80-95% by 2050 compared to 1990 as reference year. As well as meeting other requirements, these targets can be achieved by raising the contribution of renewably-generated power to Germany's gross electricity consumption to 80% by 2050. Based on Germany's potential, intermittent energy sources (IES) such as on- and offshore wind, as well as photovoltaics, are necessary sources that must be utilized in order to achieve these ambitious targets. Because of the intermittency of these sources, there will be times in which surplus power generated could be used for example for the transport sector. During these periods of surplus power, the storage capacity of hydrogen allows for a socalled ''power-to-gas'' concept whereby the surplus power can be used to produce hydrogen and oxygen by means of electrolyzers. The aim of this thesis is to identify and develop a market design that is characterized by high penetration levels of IES, supplemented by the use of hydrogen in the transport sector. Furthermore, the aim was to develop a model in which the electricity and gas sector, including a hydrogen pipeline grid, is represented so as to analyze and validate selected market designs. Therefore, potential electricity and gas markets, as well as the most important potential share and stakeholders of a hydrogen infrastructure, are analyzed. With the model developed in this thesis, an existing energy concept has been developed, analyzed and evaluated. In addition, the distribution of the hydrogen production costs was calculated by employing a Monte Carlo Simulation analysis. The developed energy concept relies on 170 GW onshore and 60 GW offshore wind capacity and these dominate the model. This leads to surplus power, especially in the federal states of Lower Saxony, Schleswig-Holstein and Mecklenburg-Western Pomerania. To supply the

    2013-01-01

    Energy security concerns due to high oil import dependence and climate change concerns due to related greenhouse gas emissions are important policy discussions in India. Could life cycle assessment (LCA) of petroleum oil products provide inputs to crude oil sourcing and domestic oil pricing policies to address the two concerns? This paper presents a baseline study on LCA of petroleum products in India from Well to Storage depending on the oil source, type of refinery, product and the selected destinations. The LCA based GHG emissions are found to be higher by 4–12 per cent than GHG emissions from direct fuel consumption alone for LPG, 7–10 per cent for Gasoline, 3–9 per cent for Diesel and 4–10 per cent for Kerosene based on various supply chain routes supplying oil to six largest cities in India. Overall the energy used in oil exploration, refinery and transportation in the LCA have a share of 72–77 per cent, 11–15 per cent and 6–8 per cent, respectively. The paper proposes imposing a relative carbon cess for various oil products in different Indian cities. States could accommodate this additional carbon cess by reducing their respective state taxes without increasing the final delivery price to the consumers. - Highlights: ► LCA emissions are found to be higher by 4–12 per cent than direct fuel consumption emissions. ► Energy used in oil exploration, refinery and transportation in the LCA have a share of 72–77 per cent, 11–15 per cent and 6–8 per cent, respectively. ► Corresponding GHG emission shares are 60–66 per cent, 23–27 per cent and 5–8 per cent, respectively. ► The source of crude oil matters. E and P energy consumption is found highest for African countries. ► Differential carbon cess could be imposed without changing final delivery price to consumers

    Today's heavy-duty natural gas-fueled fleet is estimated to represent less than 2% of the total fleet. However, over the next couple of decades, predictions are that the percentage could grow to represent as much as 50%. Although fueling switching to natural gas could provide a climate benefit relative to diesel fuel, the potential for emissions of methane (a potent greenhouse gas) from natural gas-fueled vehicles has been identified as a concern. Since today's heavy-duty natural gas-fueled fleet penetration is low, today's total fleet-wide emissions will be also be low regardless of per vehicle emissions. However, predicted growth could result in a significant quantity of methane emissions. To evaluate this potential and identify effective options for minimizing emissions, future growth scenarios of heavy-duty natural gas-fueled vehicles, and compressed natural gas and liquefied natural gas fueling stations that serve them, have been developed for 2035, when the populations could be significant. The scenarios rely on the most recent measurement campaign of the latest manufactured technology, equipment, and vehicles reported in a companion paper as well as projections of technology and practice advances. These "pump-to-wheels"(PTW) projections do not include methane emissions outside of the bounds of the vehicles and fuel stations themselves and should not be confused with a complete wells-to-wheels analysis. Stasis, high, medium, and low scenario PTW emissions projections for 2035 were 1.32%, 0.67%, 0.33%, and 0.15% of the fuel used. The scenarios highlight that a large emissions reductions could be realized with closed crankcase operation, improved best practices, and implementation of vent mitigation technologies. Recognition of the potential pathways for emissions reductions could further enhance the heavy-duty transportation sectors ability to reduce carbon emissions.

    2014-01-01

    This paper explores the bi-directional long-run relationship between energy consumption in the road transport sector with CO 2 emissions and economic growth in OECD countries. Using time series data from 1960 to 2008 and employing the Fully Modified Ordinary Least Squares cointegration approach, the paper shows positive significant long-run bi-directional relationship between CO 2 emissions and economic growth, road sector energy consumption and economic growth and CO 2 emissions and road sector energy consumption in all the OECD countries. To examine the response of each of the variables to shocks in the value of other variables, the generalized impulse response approach is employed. The response of CO 2 emissions to economic growth is initially positive in most cases but it is relatively shorter when compared to its initial response to the road transport sector energy consumption. Moreover, in most cases, the response of carbon emissions to the road transport sector energy consumption lasts longer than its response to economic growth. This implies that most of the CO 2 emissions from transport come from energy consumption, thus long-run policies related to the efficient use of energy and shifting to biofuel, renewable and nuclear energy can bring major benefits in mitigating GHG (Greenhouse Gas) emissions. - Highlights: • The relationship between GDP, energy and CO 2 in OECD's transport is investigated. • The Fully Modified Ordinary Least Squares cointegration approach was employed. • There is positive long-run bi-directional relationship between the variables. • The response of CO 2 to GDP is shorter than its response to the energy consumption

    The German Federal Government pledged itself to make a 25% reduction in national CO{sub 2} emissions by 2005 on the basis of 1990 CO{sub 2} emissions. This reduction target is valid for the entire Federal Republic. Within that context the Federal Ministry of Education, Science, Research and Technology initiated the IKARUS project (Instruments for Greenhouse Gas Reduction Strategies) in 1990. The aim of the project is to provide tools for developing strategies to reduce energy-related emissions of greenhouse gases in Germany. A range of instruments has been developed consisting of models, a data base and various tools with the aid of which different action sequences can be simulated and evaluated until the year 2020. By using the database and mainly one of the models of the project a scenario in terms of energy and carbon dioxide emissions will be sown as it could be expected for the year 2005. For this scenario as base two different strategies that hit the 25% reduction target will be discussed. Special attention is given to the transport sector. (au)

    The energy sector in Italy, as in Europe and in many other areas of the world, is undergoing rapid and profound changes. The 1986 ratification of the European Single Act was intended to create a European internal market, where circulation of people, capital, goods, and services would reach the highest possible liberalization. In 1988, in the document The Energy Internal Market, the European Union (EU) commission stressed the need for creation of an internal energy market--free of obstacles--to increase security of supply, to reduce costs, and to strengthen the competitiveness of the European economic system. In 1990, the Community Council adopted directives to implement the EU energy sector. This article describes Italy's role as part of the EU energy sector. It covers the following topics: the Italian energy sector; electricity vs gas transportation; project finance; recent developments advance Italian power industry; specifying powerplant components -- Italian stype; buyers' guide to Italian equipment, services

    1995-01-01

    For a number of years the cost of reducing CO 2 emissions in the energy sector in Denmark has been investigated in detail. The same has not been the case what concerns the cost of reducing other greenhouse gases (CH 4 and N 2 O) and especially not what concerns the possibilities of reducing greenhouse gases in other sectors in the Danish economy, i.e. agriculture, transport, industry, domestic waste and forestry. Thus, the objective of this project was twofold: 1) To calculate the national economic costs related to a number of options for reducing Danish greenhouse gas emissions (CO 2 , CH 4 and N 2 O) by using the same methodology for all important sectors in the economy and 2) To compare the cost efficiency of these options not only wihtin the individual sectors but also across the sectoral boundaries to achieve an overall view of the reduction possibilities in society and the associated costs.

    The agricultural sector will have an increasing role to play according to society needs for biobased products, including biofuels. However, it is necessary to point out national positions of strength in order to act proactive and gain the benefits for this growing marked. It is clear from this report that both agriculture and forestry, and connected industries, have great possibilities to deliver biomass resources without decreasing the current food production. From the calculations in this report, including several assumptions concerning convertibility and uncertainties about yield potentials comparing, the sector can provide up to 30 % of the existing fossil fuel consumption in the transportation sector using cereal straw. Approximately, 10 % if the wood resources are utilized and about 6 % using more waste based biomasses. Fish and slaughterhouse waste can cover up to about 9 % of the present diesel consumption. However, increased sale of bioresources for bioenergy purposes require that this resource is validated as a part of the whole farm or forestry system including political regulations like for instance the EU Natura 2000 directives. Different crops have additional functions/ effects like groundwater protection, biodiversity, soil fertility (including carbon sequestration) which needs to be included when validating such biomass crops. Furthermore, several biomass resources which are regarded as waste at present represent a much higher value, and needs to be addressed in such perspective. (author)

    This publication contains five papers that were written as a part of the GEF project, The Economics of Greenhouse Gas Limitations. The main goal of the project was to assess the greenhouse gas reductions and incremental costs of mitigation option sin Ecuador, Argentina, Senegal, Mauritius, Vietnam, Indonesia, Estonia and Hungary. In addition, regional studies were conducted for the Andean Pact nations and Southern Africa to assess various aspects of regional co-operation in reducing greenhouse gas emissions. The GEF study also involved the development of a methodological framework for climate change assessment, with a special emphasis on developing countries. These guidelines have been published in a separate document, Economics of Greenhouse Gas Limitations: Methodological Guidelines. The papers in this publication focus on various methodological and policy aspects of greenhouse gas mitigation at the sectoral level, and are outgrowth of work performed on other parts of the GEF project.

    The purpose of this project was to make a number of predictions of how the Danish energy consumption for transport purposes may evolve until 2035. The analyses include the total energy consumption for passenger and freight transport and transportation-related energy consumption in the production industry. Air and maritime transport and freight trains are not considered in the analyses. Five scenarios have been calculated, including a reference scenario, three technology scenarios (efficiency, electric vehicle, a biofuel scenario), and a combined scenario. For all scenarios, the development of fuel consumption is calculated and CO{sub 2} emissions both locally and totally are presented. The analyses show that the total energy consumption and total CO{sub 2} emission had a peak in 2007, after which the already registered decrease is likely to continue. This continued decline happens in spite of continued growth in transport services, primarily due to the assumed and expected development of more fuel-efficient cars. (ln)

    The road traffic is expected to be responsible for 9/10 of the total CO 2 emission from transportation sector in 2005. Especially private cars contribute more than half of the total CO 2 emission. Cars are not produced in Denmark, so energy efficiency of the new models depends entirely on the foreign manufacturers. Measurements of energy efficiency on test facilities show usually slightly better efficiency than on-the-road results. Efficiency estimates are based on test results. Within 10-15 years the whole car park will show essential efficiency improvement due to exchanging to newer models. Shadow price of CO 2 emission reduction is defined.

    The aim of the project is to analyse energy, environmental and economic aspects of integrating electric vehicles in the future Danish energy system. Consequences of large-scale utilisation of electric vehicles are analysed. The aim is furthermore to illustrate the potential synergistic interplay between the utilisation of electric vehicles and large-scale utilisation of fluctuating renewable energy resources, such as wind power. Economic aspects for electric vehicles interacting with a liberalised electricity market are analysed. The project focuses on battery electric vehicles and fuel cell vehicles based on hydrogen. Based on assumptions on the future technical development for battery electric vehicles, fuel cell vehicles on hydrogen, and for the conventional internal combustion engine vehicles, scenarios are set up to reflect expected options for the long-term development of road transport vehicles. Focus is put on the Danish fleet of passenger cars and delivery vans. The scenario analysis includes assumptions on market potential developments and market penetration for the alternative vehicles. Vehicle replacement rates in the Danish transport fleet and the size of fleet development are based on data from The Danish Road Directorate. The electricity supply system development assumed is based on the Danish energy plan, Energy 21, The Plan scenario. The time horizon of the analysis is year 2030. Results from the scenario analysis include the time scales involved for the potential transition towards electricity based vehicles, the fleet composition development, the associated developments in transport fuel consumption and fuel substitution, and the potential CO{sub 2}-emission reduction achievable in the overall transport and power supply system. Detailed model simulations, on an hourly basis, have furthermore been carried out for year 2005 that address potential electricity purchase options for electric vehicles in the context of a liberalised electricity market

    This paper contains a tentative suggestion of how to take into account the value of changes in price volatility in real world cost-benefit analyses. Price volatility is an important aspect of security of supply which first of all concerns physical availability, but assuming that consumers are risk averse, security of supply can also be viewed as a matter of avoiding oscillations in consumption originating from volatile prices of for instance oil. When the government makes transport-related choices on behalf of the consumers, the effect on oscillations in general consumption should be included in the policy assessment taking into account the most significant correlations between prices of alternative fuels and between fuel prices and consumption in general. In the present paper, a method of valuing changes in price volatility based on portfolio theory is applied to some very simple transport-related examples. They indicate that including the value of changes in price volatility often makes very little difference to the results of cost-benefit analyses, but more work has to be done on quantifying, among other things, consumers' risk aversion and the background standard deviation in total consumption before firm conclusions can be drawn.

  8. Regulatory reform in Mexico's natural gas sector

    International Nuclear Information System (INIS)

    1996-01-01

    In recent years Mexico has implemented remarkable structural changes in its economy. However, until recently its large and key energy sector was largely unreformed. This is now changing. In 1995 the Mexican Government introduced legislative changes permitting private sector involvement in natural gas storage, transportation and distribution. Subsequent directives set up a detailed regulatory framework. These developments offer considerable promise, not only for natural gas sector development but also for growth in the closely linked electricity sector. This study analyses the changes which have taken place and the rationale for the regulatory framework which has been established. The study also contains recommendations to assist the Government of Mexico in effectively implementing its natural gas sector reforms and in maximizing the benefits to be realised through the new regulatory framework.

    Transportation demands a large and increasing share of total energy consumption in Europe. At the same time many European countries are facing difficult decisions in achieving their long term environmental goals. Therefore energy policy, environmental policy and transport policy should be seen and discussed in a common perspective. In particular the relative contribution from the transport sector and the energy sector involves a number of important and difficult issues. The aim of the conference was to bring together economists, scientists, manufactures, energy planners, transport planners, and decision makers in order to discuss the importance of the transport sector in relation to energy demand and long term environmental goals. General conference sessions covered. Trends in Transport Energy Demand and Environmental constraints, Technological Development and New Transport Systems, Lifestyle Changes and the Transport Sector, Megacities: Solutions to the Transport and Air Pollution Problems, Effectiveness of Public Policies, Transport and Energy sector, and Methods, Models and Data. The conference took place at Hotel Marienlyst, Elsinore, Denmark and attracted wide interest. The participants represented 14 different countries covering international organisations, ministries, universities, research centres, consulting firms, industry etc. (EG)

    Transport is the sector with the highest final energy consumption and, without any significant policy changes, is forecast to remain so. In 2008, the IEA published 25 energy efficiency recommendations, among which four are for the transport sector. The recommendations focus on road transport and include policies on improving tyre energy efficiency, fuel economy standards for both light-duty vehicles and heavy-duty vehicles, and eco-driving. Implementation of the recommendations has been weaker in the transport sector than others. This paper updates the progress that has been made in implementing the transport energy efficiency recommendations in IEA countries since March 2009. Many countries have in the last year moved from 'planning to implement' to 'implementation underway', but none have fully implemented all transport energy efficiency recommendations. The IEA calls therefore for full and immediate implementation of the recommendations.

    The Federal Environment Agency is therefore proposing a multitude of measures which have the potential to significantly reduce the CO{sub 2} emissions caused by transport and to thus achieve the German Federal Government's climate protection objectives. The measures target both freight and passenger transport and cover all transport modes (heavy goods vehicles, passenger cars, inland waterways, rail, air, pedestrians and bicycles). The Federal Environment Agency suggests a range of complementary measures in the following fields: - Traffic avoidance: Influencing / reducing transport demand and shortening distances. - Modal shift: Shifting transport to more environmentally friendly modes. - Optimising transport: Better utilisation of existing transport capacities. - Economic measures and - direct emission reduction on vehicles. In line with this, the measures and instruments proposed focus on the following areas: - Traffic-reducing through town planning and transport planning - Promoting environmentally friendly transport modes - Economic measures - Measures to improve vehicle and fleet efficiency - Consumer information and driving behaviour in road traffic The table below provides an overview of the measures and their reduction potential for the years 2020 and 2030. The calculated CO{sub 2} savings result from the divergence from the trend scenario which was calculated using the ''TREMOD'' model and is based on measures for the transport sector which have already been adopted. The potentials from the various individual measures proposed by the Federal Environment Agency cannot simply be added up, since the measures may be mutually reinforcing or reducing each others effect. For instance, if fewer heavy goods vehicles are on the road because of a switch to rail, this reduces the absolute reduction that could be achieved by the HGV fleet through e.g. the use of low-friction oils and low-rolling-resistance tyres.

    2017-03-01

    The paper examines the impacts of financial development on sectoral carbon emissions (CO 2 ) for environmental quality in Malaysia. Since the financial sector is considered as one of the sectors that will contribute to Malaysian economy to become a developed country by 2020, we utilize a cointegration method to investigate how financial development affects sectoral CO 2 emissions. The long-run results reveal that financial development increases CO 2 emissions from the transportation and oil and gas sector and reduces CO 2 emissions from manufacturing and construction sectors. However, the elasticity of financial development is not significant in explaining CO 2 emissions from the agricultural sector. The results for short-run elasticities were also consistent with the long-run results. We conclude that generally, financial development increases CO 2 emissions and reduces environmental quality in Malaysia.

    In this paper, we analyze differences in per capita carbon dioxide emissions from 1996 to 2010 in six sectors across 28 provinces in China and examine the σ-convergence, stochastic convergence and β-convergence of these emissions. We also investigate the factors that impact the convergence of per capita carbon dioxide emissions in each sector. The results show that per capita carbon dioxide emissions in all sectors converged across provinces from 1996 to 2010. Factors that impact the convergence of per capita carbon dioxide emissions in each sector vary: GDP (gross domestic product) per capita, industrialization process and population density impact convergence in the Industry sector, while GDP per capita and population density impact convergence in the Transportation, Storage, Postal, and Telecommunications Services sector. Aside from GDP per capita and population density, trade openness also impacts convergence in the Wholesale, Retail, Trade, and Catering Service sector. Population density is the only factor that impacts convergence in the Residential Consumption sector. - Highlights: • Analyze differences in CO 2 emissions in six sectors among 28 provinces in China. • Examine the convergence of CO 2 emissions in six sectors. • Investigate factors impact on convergence of CO 2 emissions in each sector. • Factors impact on convergence of per capita CO 2 emissions in each sector vary

This research simulates increased productivity in the maritime sector (consisting of the fisheries, oil, gas sub-sector and marine transport services sector using the Global Trade Analysis Project (GTAP version 8. Simulation analysis showed an increase in productivity in the maritime sector has a positive impact on welfare, real GDP, and trade balance of Indonesia. However, the impact of the increase in productivity is not followed by an increase in output in all sectors. This indicates that if the increase in productivity occurs only in the maritime sector alone without being followed by an increase in productivity in other sectors, the sectoral performance is not optimal.DOI: 10.15408/sjie.v5i2.3403

    The energy sector is a key driver of the economic pillar of Vision 2030. As the economy grows, urbanization intensifies and incomes increase, corporate and household demand for energy also rises. To meet this growth in demand for energy, the sector needs to increase investments and diversify into more sources of energy such as geothermal and wind power. It is therefore critical that focus is directed towards development and sustainability of the energy sector to ensure delivery of least cost power that will improve Kenya's competitiveness and achieve the Vision 2030 objective of 10% average annual economic growth.

Las mujeres en España presentan tasas de desempleo, trabajo temporal y a tiempo parcial mucho mayores que los hombres. Además, las condiciones de acceso al mercado de trabajo y las condiciones en las que éste se desempeña están también muy relacionadas con la clase social. Las mujeres cubren la escasez de servicios públicos destinados al cuidado de las criaturas pequeñas y de las personas mayores o dependientes, y realizan una labor de cuidadoras informales sin reconocimiento social, lo cual les impide el acceso a un puesto de trabajo o su mantenimiento y limita de forma decisiva las posibilidades de desarrollo y progreso profesional. Todo ello indica una clara diferencia con respecto a los hombres en cuanto a la frecuencia de contratos temporales y de tiempo parcial, así como en la segregación laboral, tanto horizontal como vertical. Estos aspectos de segregación son más evidentes en las mujeres de clases sociales menos privilegiadas, en las que se concentran las peores condiciones de acceso al mercado laboral y de trabajo. En España es imprescindible llevar a cabo políticas que ofrezcan servicios que permitan compatibilizar la vida laboral y familiar en condiciones de mayor equidad, tanto en razón de género como de clase social.In the last 25 years, the production sector in Spain has undergone important changes.

    There is a growing need of evaluating experiences with the liberalization of different sectors in the Netherlands. To what extent do the technical, economical and organizational characteristics of a sector determine the options to deal with competition? And to what extent does the type of competition determine whether the aimed for improvement of the efficiency and effectiveness of the service will be realized or not? Thereto, a systematic comparative analysis of infrastructure-related sectors has been carried out. In this report the experiences of the liberalization process in the electric and gas utilities sectors and the public transportation (buses and railway) sector are translated to preliminary conclusions and new research questions with respect to the possibilities to introduce competition in the water supply sector. refs

Six sectors (agriculture; manufacturing; building and construction; wholesale and retail; transportation and communication of the economy were examined. The long run regression estimate showed that gasoline price is a significant determinant output in all sectors examined with exception to the building and construction sector while the short run error correction estimate revealed that only output of the agriculture and the manufacturing sectors of the Nigerian economy is affect by gasoline price increase in the short run. The study recommended among others the need for the government to ensure adequate power supply in order to reduce the over reliance of economics sectors on gasoline as a prime source of power.

    The catering industry is a service characterized by a contract between customer and supplier. In institutional catering industry, the customer is represented by public administration; in private catering industry, the customer is represented by privates. The annual catering trades size is about 6.74 billions of euros, equally distributed between health sector (hospitals, nursing homes), school sector and business sector (ivorkplace food service), with the participation of nearly 1.200 firms and 70.000 workers. Major services include off-premises catering (food prepared away from the location where it's served) and on-premises catering (meals prepared and served at the same place). Several tools and machineries are used during both warehousing and food refrigerating operations, and during preparation, cooking, packaging and transport of meals. In this sector, injuries, rarely resulting serious or deadly, show a downward trend in the last years. On the contrary, the number of occupational diseases shows an upward trend. About the near future, the firms should become global outsourcer, able to provide other services as cleaning, transport and maintenance. In addition, they should invest in innovation: from tools and machineries technology to work organization; from factory lay-out to safely and health in the workplaces.

    1999-01-01

    The Kyoto Protocol sets greenhouse gas (GHG) reduction targets for the post-2000 period. If ratified, Canada will be committed to reduce emissions of GHGs by 6 per cent below 1990 levels during the period 2008-2012. A recommended national strategy is to establish 'issue tables' that will advise the Ministers of Energy and Environment on preferred options to reach the Kyoto target and to identify early actions that can be taken. The 'Transportation Table' which is the focus of this paper, is one of the 15 sectoral tables. The Transportation Table will identify by July 1999, specific measures to mitigate GHG emissions from Canada's transportation sector. Currently, GHG emissions from the transportation sector are predicted to be 27 per cent above 1990 levels by 2010. Fuel taxes, emissions trading, and research into improved vehicle technologies and automotive fuels are some of the recommended options which can help reduce emissions trading from the transportation sector. Studies are underway to deal with emissions from transport in two sub-groups, freight and passenger. 1 fig

    The waste management section of this report deals with two sectors: land disposal of solid waste and wastewater treatment. It provides background information on the type of emissions that contribute to the greenhouse gases from these two sectors, presents both sector current status in Lebanon, describes the methodology followed to estimate the corresponding emissions, and presents the results obtained regarding greenhouse emissions. The total methane emissions from solid waste disposal on land are 42.804 Gg approximately. There are no emissions from wastewater and industrial handling systems because, for the target year 1994, there was no treatment facilities in Lebanon. The wastewater (municipal, commercial and industrial) was directly discharged into the sea, rivers, ravines or septic tanks which indicate that methane or nitrous oxide emissions are significant if not nonexistent. Note that this situation will change in the future as treatment plants are being constructed around the country and are expected to come into operation by the year 2000

    In this paper we claim that distance alone is a poor proxy for international transport costs in empirical studies. We model a manufacturing and a transport sector and let the level of manufacturing exports determine the demand for transport services. Above a particular trade level, transport service suppliers find it profit-maximizing to invest in an advanced transport technology, which lowers their marginal costs and as a consequence, equilibrium transport prices. Transport costs thus vary w...

    Full Text Available Many infectious and chronic diseases are either directly or indirectly sensitive to the climate. Managing this climate sensitivity more effectively requires new working relationships between the health sector and the providers of climate data and information. In Africa, where communities are particularly vulnerable, Ministries of Health and National Meteorological Services need to collaborate to reduce the burden of climate related ill health. The Ministry of Health and the National Meteorological Agency of Ethiopia have made significant progress towards the development of a climate-informed early warning and response system for diseases such as malaria and other climate-sensitive diseases. An important enabling mechanism is a Climate and Health Working Group, which is a multi-sectoral partnership created to spearhead the use of climate information for health interventions. While this is a work in progress, the key ingredients necessary to sustain such a joint venture are described to encourage similar activities in other countries faced with a growing climate-sensitive disease burden, to facilitate networking and to increase the return from the investment.De nombreuses infections et maladies chroniques sont sensibles, directement ou indirectement, au climat.

    2004-05-01

    In the last 25 years, the production sector in Spain has undergone important changes. Among these changes, the important growth of the services sector at the expense of the primary sector, the increasing flexibility of the labour market, and the rise in the female workforce could be considered as the most relevant ones. Spanish women have higher rates of unemployment, temporary jobs and part time contracts than Spanish men. Moreover, job access and work conditions are highly related to gender and social class. Because women are forced to compensate for the scarcity of social services for caring for young children and for dependent elderly, they become informal and socially unrecognised caregivers, preventing them from getting or holding a job, and significantly limiting their opportunities for professional development. These social conditions are closely related with the fact that work conditions for women involve higher temporality rates and shorter contracts than those of men, given the sectors and jobs in which they tend to work (due to segregation). Similarly, workers of the less privileged social classes have poorer work conditions. Thus, women of the lower income class are mainly suffering the worst job contracts and the poorest work conditions. More social services are needed to make it possible to attend to family needs and still be able to access and maintain a job contract. Policies tending to conciliate labour and family life are indispensable and should incorporate measures to equally distribute the house keeping activities between women and men.

These will determine whether any potential economic advantage lies in novel forms of fuel. Meanwhile, continuing development of sintered UO{sub 2} in the simple rod geometry will provide stiff competition. (author) [French] Maintenant que plusieurs reacteurs alimentes au bioxyde d'uranium sont en exploitation normale, on peut considerer que les performances nucleaires de cette matiere sont satisfaisantes et il faut se rejouir de voir se realiser encore de nouveaux progres dans cette branche de la technologie. L'evenement le plus remarquable dans ce domaine est assurement la decouverte des chercheurs de Battelle qui ont observe recemment qu'a haute temperature un monocristal de UO{sub 2} etait doue d'une tres forte conductivite thermique. A la suite d'une controverse sur ce point, une experience d' irradiation faite a Chalk River a montre que les grains de grande dimension formes dans des elements combustibles en fonctionnement ne presentent pas necessairement cette conductivite accrue. Les experiences de laboratoire ont revele que cette augmentation de la conductivite ne se presente que dans les compositions hypostoechiometriques et ne depend guere de l'absence de joint de grain. En fait, la forte conductivite peut etre obtenue dans des frittes polycristallins, si l'on maintient la composition stoechiometrique optimum. On sait depuis longtemps qu' il est possible de reduire rallongement des gaines en menageant des depressions sur chacune des bases des pastilles de UO{sub 2}; on a montre par la suite que si on laissait un vide aux extremites de l'empilement des pastilles, la tendance du combustible a remplir ce vide etait entravee par la dilatation diametrale des pastilles et leur interaction mecanique avec la gaine. On a realise un tres grand progres en vue de reduire los distensions de la gaine lorsqu'on s'est rendu compte que les dilatations longitudinales

  7. The gas market and sector in France. Situation and predictions 2018 - Sector and competitive analysis

    International Nuclear Information System (INIS)

    2017-01-01

    Through a detailed analysis of market determining factors, of evolutions of supply and demand, and of major events in firms life, this set of two reports proposes an analysis of the recent situation of the gas sector and of the evolutions of the competitive game. The first report on situation and predictions which is updated three times a year, proposes a synthesis on the consequences of the evolution of the economic environment, on major trends noticed for the sector, and on predictable evolutions. It proposes the most recent predictions regarding natural gas consumption in France and the turnover of the gas sector. It highlights recent events for companies of the sector: takeovers, investments, restructuring, introduction of new products, and so on. It proposes a sector-based dashboard which contains all the critical figures useful to analyse the sector situation (activity determining factors, key figures for the sector and its environment). The second report (the annual one) proposes an overview of trends and competition within the gas sector. It gives an overview of some basic aspects of the activity (sector organisation, gas categories, main customer markets, gas consumption in industry), and of its determining factors, analyses the sector environment (sites connected to the natural gas network, evolution of average temperatures in France, production by chemical industry, by the food industry, and by metallurgy and oil refining, thermal production of electricity, regulatory evolution regarding supports to energy efficiency, and new opportunities). The evolution of the sector activity is analysed through its trends and indicators (turnovers, gas consumption, butane-propane deliveries, wholesale prices, regulated tariffs). The economic structure is also analysed: aspects related to the upstream part (extraction, injection of biogas, natural gas main input and output points, transport and storage, natural gas distribution), and aspects related to gas provision

    1990-02-01

    The Cuban oil industry started in 1860 when an oil well was drilled in Matanzas province. About 200 wells were drilled up until 1959. In the past 30 years, the oil industry has become a priority sector; in 1985-1990, about US$500 million were invested in the industry, with increases in exploration and well drilling activity. Recently completed works include pipelines and a supertanker terminal. About 10 million tons of oil are imported annually and local production averages about 800,000 metric tons per year. Most of the oil found in Cuba so far is of the heavy type, as found in western Canada. There are about 10 small and medium-sized oil deposits, mainly located in the north. The most promising oil field is at Varadero, whose characteristics are similar to the Cold Lake field in Alberta. Cuban oil refining capacity is over 7.6 million metric tons per year, and additional capacity is being constructed. All imports of oil industry equipment are conducted via state trading agencies. Export opportunities of interest to Canadian companies are outlined, along with monetary constraints affecting imports to Cuba, financing and export insurance programs available to Canadian companies, and recommendations to Canadian exporters. A list of industry/government contacts is included

    2017-06-01

    Injury to children in Europe, resulting in both death and disability, constitutes a significant burden on individuals, families and society. Inequalities between high and low-income countries are growing. The World Health Organisation Health 2020 strategy calls for inter-sectoral collaboration to address injury in Europe and advocates the whole of government and whole of society approaches to wicked problems. In this study we explore which sectors (e.g. health, transport, education) are relevant for four domains of child safety (intentional injury, water, road and home safety). We used the organigraph methodology, originally developed to demonstrate how organizations work, to describe the governance of child safety interventions. Members of the European Child Safety Alliance, working in the field of child safety in 24 European countries, drew organigraphs of evidence-based interventions. They included the different actors involved and the processes between them. We analyzed the organigraphs by counting the actors presented and categorizing them into sectors using a pre-defined analysis framework. We received 44 organigraphs from participants in 24 countries. Twenty-seven sectors were identified across the four domains. Nine of the 27 identified sectors were classified as 'core sectors' (education, health, home affairs, justice, media, recreation, research, social/welfare services and consumers). This study reveals the multi-sectoral nature of child safety in practice. It provides information for stakeholders working in child safety to help them implement inter-sectoral child safety interventions taking a whole-of-government and whole-of-society approach to health governance. © The Author 2017.

  12. Private Sector Savings

    Directory of Open Access Journals (Sweden)

    Pitonáková Renáta

    2018-03-01

    Full Text Available The majority of household savings are in the form of bank deposits. It is therefore of interest for credit institutions to tailor their deposit policy for getting finances from non-banking entities and to provide the private sector with the loans that are necessary for investment activities and consumption. This paper deals with the determinants of the saving rate of the private sector of Slovakia. Economic, financial and demographic variables influence savings. Growth of income per capita, private disposable income, elderly dependency ratio, real interest rate and inflation have a positive impact on savings, while increases in public savings indicate a crowding out effect. The inflation rate implies precautionary savings, and dependency ratio savings for bequest. There are also implications for governing institutions deciding on the implementation of appropriate fiscal and monetary operations.

    de Ia Rue du Can, Stephane; Price, Lynn

    2008-01-01

    Integrated assessment models have been used to project both baseline and mitigation greenhouse gas emissions scenarios. Results of these scenarios are typically presented for a number of world regions and end-use sectors, such as industry, transport, and buildings. Analysts interested in particular technologies and policies, however, require more detailed information to understand specific mitigation options in relation to business-as-usual trends. This paper presents sectoral trend for two of the scenarios produced by the Intergovernmental Panel on Climate Change's Special Report on Emissions Scenarios. Global and regional historical trends in energy use and carbon dioxide emissions over the past 30 years are examined and contrasted with projections over the next 30 years. Macro-activity indicators are analyzed as well as trends in sectoral energy and carbon demand. This paper also describes a methodology to calculate primary energy and carbon dioxide emissions at the sector level, accounting for the full energy and emissions due to sectoral activities.

  16. Sector retinitis pigmentosa.

    Van Woerkom, Craig; Ferrucci, Steven

    2005-05-01

    Retinitis pigmentosa (RP) is one of the most common hereditary retinal dystrophies and causes of visual impairment affecting all age groups. The reported incidence varies, but is considered to be between 1 in 3,000 to 1 in 7,000. Sector retinitis pigmentosa is an atypical form of RP that is characterized by regionalized areas of bone spicule pigmentation, usually in the inferior quadrants of the retina. A 57-year-old Hispanic man with a history of previously diagnosed retinitis pigmentosa came to the clinic with a longstanding symptom of decreased vision at night. Bone spicule pigmentation was found in the nasal and inferior quadrants in each eye. He demonstrated superior and temporal visual-field loss corresponding to the areas of the affected retina. Clinical measurements of visual-field loss, best-corrected visual acuity, and ophthalmoscopic appearance have remained stable during the five years the patient has been followed. Sector retinitis pigmentosa is an atypical form of RP that is characterized by bilateral pigmentary retinopathy, usually isolated to the inferior quadrants. The remainder of the retina appears clinically normal, although studies have found functional abnormalities in these areas as well. Sector RP is generally considered a stationary to slowly progressive disease, with subnormal electro-retinogram findings and visual-field defects corresponding to the involved retinal sectors. Management of RP is very difficult because there are no proven methods of treatment. Studies have shown 15,000 IU of vitamin A palmitate per day may slow the progression, though this result is controversial. Low vision rehabilitation, long wavelength pass filters, and pedigree counseling remain the mainstay of management.

    International Nuclear Information System (INIS)

    Luty, Markus A.; Terning, John

    1999-01-01

    We review recent work on realistic models that break supersymmetry dynamically and give rise to composite quarks and leptons, all in a single sector. These models have a completely natural suppression of flavor-changing neutral currents, and the hierarchy of Yukawa couplings is explained by the dimensionality of composite states. The generic signatures are unification of scalar masses with different quantum numbers at the compositeness scale, and lighter gaugino, Higgsino, and third-generation sfermion masses

  20. Composite Dark Sectors

    Carmona, Adrian

    2015-06-01

    We introduce a new paradigm in Composite Dark Sectors, where the full Standard Model (including the Higgs boson) is extended with a strongly-interacting composite sector with global symmetry group G spontaneously broken to H is contained in G. We show that, under well-motivated conditions, the lightest neutral pseudo Nambu-Goldstone bosons are natural dark matter candidates for they are protected by a parity symmetry not even broken in the electroweak phase. These models are characterized by only two free parameters, namely the typical coupling g D and the scale f D of the composite sector, and are therefore very predictive. We consider in detail two minimal scenarios, SU(3)/[SU(2) x U(1)] and [SU(2) 2 x U(1)]/[SU(2) x U(1)], which provide a dynamical realization of the Inert Doublet and Triplet models, respectively. We show that the radiatively-induced potential can be computed in a five-dimensional description with modified boundary conditions with respect to Composite Higgs models. Finally, the dark matter candidates are shown to be compatible, in a large region of the parameter space, with current bounds from dark matter searches as well as electroweak and collider constraints on new resonances.

  1. Estimated United States Transportation Energy Use 2005

    Energy Technology Data Exchange (ETDEWEB)

    Smith, C A; Simon, A J; Belles, R D

    2011-11-09

    A flow chart depicting energy flow in the transportation sector of the United States economy in 2005 has been constructed from publicly available data and estimates of national energy use patterns. Approximately 31,000 trillion British Thermal Units (trBTUs) of energy were used throughout the United States in transportation activities. Vehicles used in these activities include automobiles, motorcycles, trucks, buses, airplanes, rail, and ships. The transportation sector is powered primarily by petroleum-derived fuels (gasoline, diesel and jet fuel). Biomass-derived fuels, electricity and natural gas-derived fuels are also used. The flow patterns represent a comprehensive systems view of energy used within the transportation sector.

  2. Dynamics of final sectoral energy demand and aggregate energy intensity

    International Nuclear Information System (INIS)

    Lescaroux, Francois

    2011-01-01

    This paper proposes a regional and sectoral model of global final energy demand. For the main end-use sectors of consumption (industrial, commercial and public services, residential and road transportation), per-capita demand is expressed as an S-shaped function of per-capita income. Other variables intervene as well, like energy prices, temperatures and technological trends. This model is applied on a panel of 101 countries and 3 aggregates (covering the whole world) and it explains fairly well past variations in sectoral, final consumption since the beginning of the 2000s. Further, the model is used to analyze the dynamics of final energy demand, by sector and in total. The main conclusion concerns the pattern of change for aggregate energy intensity. The simulations performed show that there is no a priori reason for it to exhibit a bell-shape, as reported in the literature. Depending on initial conditions, the weight of basic needs in total consumption and the availability of modern commercial energy resources, various forms might emerge. - Research Highlights: → The residential sector accounts for most of final energy consumption at low income levels. → Its share drops at the benefit of the industrial, services and road transportation sectors in turn. → Sectoral shares' pattern is affected by changes in geographic, sociologic and economic factors. → Final energy intensity may show various shapes and does not exhibit necessarily a bell-shape.

  3. Challenges and policies in Indonesia's energy sector

    International Nuclear Information System (INIS)

    Dutu, Richard

    2016-01-01

    Fossil fuels are central to Indonesia's energy policy, and its main source of export revenues. However, insufficient investment, the lack of transport infrastructure and an unwieldy regulatory environment are inhibiting the sector from reaching its full potential. Looking ahead, growing environmental concerns combined with sharp falls in coal prices and the on-going shale gas revolution call into question the sustainability of an energy strategy based almost exclusively on fossil fuels. This viewpoint challenges Indonesia's current energy policy and proposes ways to increase its energy efficiency and use of renewables. In particular, its gas sector should be further developed to plug the gap until sufficient renewable energy, especially geothermal, comes on line. Government control over the oil industry via state-owned Pertamina should be gradually reduced. Clarifying, streamlining and publicising simple regulations in energy, especially regarding land rights and on-shore processing, and removing foreign-ownership restrictions will help bring much needed investment. The pressure on the environment of natural resource exploitation should also be addressed by properly defining property rights and regulations regarding forest land, and implementing a positive implicit carbon price. - Highlights: • Indonesia's energy sector faces many regulatory, environmental and infrastructure hurdles. • Indonesia's energy policy can be improved through greater use of renewables, especially geothermal. • The gas sector should be further developed until more renewable energy come on line. • Government control over the oil industry should be reduced to boost investment. • Clarifying and simplifying regulations is key to attracting foreign companies and protecting the environment.

  4. Private sector participation in power sector in India

    Ranganathan, V.

    1992-01-01

    The Indian Government is currently thinking of allowing private sector to participate in power sector inviting private sector to generate electricity mainly from coal. The main motivation is resource mobilization from private sector, since the Plan funds are diverted to rural development away from power sector; and yet the massive expansion has to be financed. The paper analyzes the inherent difficulties and contradictions in the Government's proposal, such as co-existence of high cost private power and low cost public power, the potential goal-conflicts of private and public utilities and the constraints in raising finance. It suggests a different model in order to make the privatization proposition feasible. 12 refs

    Extension of European Union causes increase of free transfer of people and goods. At the same time they raised the problems associated with the transport, e.g. congestion and related accidents on roads, air traffic delays and more. To increase the efficiency and safety of transport, the European Commission supports the introduction of intelligent transport systems and services in all transport sectors. Implementation of intelligent transport systems and services in the road transport reduces accident frequency, increases the capacity of existing infrastructure and reduces congestions. Use of toll systems provides resources needed for the construction and operation of a new road network, improves public transport, cycling transport and walking transport, and also their multimodal integration with individual car transport.

    Hydro-Quebec's successful partnership with the private sector, in particular with the consulting engineering profession, was highlighted, as an indication of the unprecedented economic activity generated by the public utility throughout its fifty year existence, and most noticeably since the 1960s, when the 'Quiet Revolution' of the Lesage government set the tone for favoring Quebec consulting firms. The Corporation's rapid growth also stimulated the development of the province's private engineering sector, and served as the incentive for electrical equipment manufacturers, and the source of new skills and enterprises emerging from environmental concerns. Special mention was made of the economic advances made by native peoples through their involvement in land clearing, excavation, construction, and provision and transportation of supplies to remote construction sites

    Energy - alongside knowledge, creativity and capital - is one of the fundamental necessities of humankind. Modern life is indeed dependent on energy, especially electricity and natural gas, the grid-connected energies, for its power, heating, cooling and traffic. To ensure security in the supply of energy, world energy hunger must be taken into account. Competition for primary energy resources will increase and the processes for their transformation from raw materials into consumable energy will have to be made more efficient, environmentally friendly and sustainable. Research into new sources of energy has to continue. After the respectable results of the industrial sector to decouple growth and energy consumption in future the transport and building sectors will have to intensify their efforts to reduce energy use intensity

    This paper investigates the determinants of informal economic activity. We present two equilibrium models of informality and test their implications using a survey of 48,000+ small firms in Brazil. We define informality as tax avoidance; firms in the informal sector avoid tax payments but suffer other limitations. In the first model there is a single industry and informal firms face a higher cost of capital and a limitation on size. As a result informal firms are smaller and have a lower capi...

    The construction sector is characterized by high complexity due to several factors. There are a lot of processes within the building sites and they need the use of different materials with the help of appropriate technologies. Traditional materials have evolved and diversified, meanwhile new products and materials appeared and still appear, offering services which meet user needs, but that often involve risks to the health of workers. Research in the field of materials, promoted and carried out at various levels, has led to interesting results, encoded in the form of rules and laws.

    Information on the emissions and energy consumption of different vehicles per transported amount of goods has up to last years been minimal. The unit emissions mean the amount of harmful compounds in the flue gases of a vehicle per service, time or energy unit. National three-year MOBILE 2-research program, started in 1999, determines the unit emissions of all the traffic sectors in Finland. VTT Building and Transport mainly carry out the research, but the Institute of Transportation Engineering of the Tampere University of Technology (TTKK) is responsible for a part of the research. The objective of the project is to create common rules for the determination of unit emissions values, and to determine the best possible values for Finnish conditions. Unit emission data is mainly needed for evaluation of the environmental impacts of production plants and other activities containing transportation of commodities. At the web sites of VTT Building and Transport there are about 60 pages of text and tables (about 4000 values) on unit emissions. The URL of the pages is http://www.vtt.fi/rte/projects/lipastoe/index.htm. These web pages present data on all the transportation sectors (road, railroad, water and air transportation), most of the materials concerning road transportation. Following compounds and values are included: CO, HC, NO x , particulates, SO 2 , CO 2 and energy consumption. Methane and nitrous oxide emissions values have also been presented

    The Asn is loaded with the control of the nuclear safety and the radiation protection in France: it provides this control, in the name of the state, to protect the workers, the patients, the public and the environment of the risks in relation with nuclear activities. The control is the core business of Asn. Asn so checks the nuclear basic installations (I.N.B.), since their conception until their dismantling, the pressure equipment specially conceived for these installations, the management of the radioactive waste as well as the transport of radioactive substances. Asn also checks all the industrial and research installations as well as the hospitals where are used ionizing radiations. It is a more recent profession there, because dating the reform of the control of the nuclear power of 2002, which constitutes that of the radiation protection. The first responsibility of the activities at risks falls to the one who begins them.

    Transport makes an important contribution to our welfare, which is expressed in a large consumer surplus or added value for society. Some people define this consumer surplus as external benefits, if the positive consequences of transport fall to others. But unfortunately transport is also accompanied by negative effects for society. If the causer does not pay all the costs of the negative effects of transport, called external or social costs. These social costs above all lie in the area of air pollution, noise nuisance, land use, cutting through the landscape, accident risk and - in a certain way - also congestion. Just like all the other players, the transport industry has a social responsibility to bear the social costs created. For example compensating victims for damage incurred, like paying emotional damages to surviving relatives of traffic casualties. In an ideal situation, transport will remove all the negative effects by source or end-of-pipe measures, so that the social costs disappear. If we compensate, reduce and remove negative effects by means of charging or standards, we speak of internalisation of the social costs. The best way to internalise the costs is with a 'market model' (Pigou/Coase), but a 'government model' is also possible in certain conditions. Firstly, we will discuss the ideal market model and then we will discuss the government model as the second-best solution. The following points will be discussed: Marginal costs are by definition costs of most expensive measure to achieve objectives; No mode of transport pays all marginal costs; Transport costs rise least with road transport and most with inland shipping; Market model or government model?; Government model will place heavier burdens on rail and inland shipping; In practice, the unpaid bill is lower than in theory; Wishes of industry and society can be combined by politicians; What is sauce for the goose is sauce for the gander is necessary and feasible

    Full Text Available The paper points to recent developments in the tourism sector and highlights the leading factors of the internationalization of tourists travel and of tourism services, including information technologies, as well as the internationalization of hotel and tourism enterprises. Without neglecting the huge subsector of small and medium-sized enterprises, it describes typical features related to the composition of the labour force and to working conditions. It raises questions concerning the difficulties faced by the sector in attracting and retaining skilled workers in enhancing the skills of newcomers to the labour market in order to stabilize the sector’s labour force, while increasing the productivity of enterprises and the quality of services. Particular emphasis is put on new forms of management entailing new skills requirements, with a general tendency towards increased worker responsibility in an environment of flat hierarchies, multiskilling and teamwork.

    The recent announcement by the Australian Government of funding for a dramatic increase in supply infrastructure for Compressed Natural Gas (CNG) powered vehicles has shored up predictions that natural gas will achieve a thirty-fold increase in its share of the Australian transport energy market by 2015. This projection, would put sales of natural gas for transport fuel in the year 2014/15 at about 10% of current retail sales across the nation. In the general transport sector, the lower particulate and noise pollution, compared with diesel-powered vehicles, is a significant advantage

    Diffuse sources are an increasingly serious contributor to water pollution. To tackle the problem one must understand it fully and be able to trace pollutants back to their source or sources. Unfortunately, the map for diffuse sources is incomplete. One significant gap, and the focus of this study, is emissions from ship and small craft engines. For the purpose of this study shipping has been split into three categories: seagoing vessels, the inland carrying trade, and recreational craft. The type of fuel used by ships and small craft varies considerable, from heavy fuel oil to petrol. Emissions from combustion include COx, SOx, NOx, carbon compounds, PAHs and other micropollutants. The most important factors determining the content of exhaust emissions are fuel type, engine type, engine use and engine tuning. The quantities of the different engine emissions are calculated for each shipping sector by multiplying its energy consumption by `emission factors`. Emission factors indicate how much will be released during the combustion of one kilogram of fuel. However, the use of emission factors is fraught with difficulty. Differing engine types and uses mean that emission factors give only a rough indication of emission contents. Indeed, emission factors are unavailable for some engines and substances, and in these cases estimates have been made. An estimate of the energy consumption of a particular shipping sector can be arrived at by studying ship movements and rates of fuel consumption. For seagoing vessels and the inland carrying trade, ship movements are recorded and known. For smaller recreational craft an estimate has been made. On the Dutch continental shelf seagoing vessels consume around 920,000 tonnes of heavy fuel oil each year, producing 62,600 tonnes NOx, 36,000 tonnes SOx, 4,300 tonnes soot and 2,500 tonnes carbon compounds. Other emissions include, but may not be limited to, microcontaminants, e.g. nitro-PAHs and dioxins. The quantity of

    In Part II of this work we present the results of the downscaled offline Weather Research and Forecasting/Community Multiscale Air Quality (WRF/CMAQ) model, included in the "Technology Driver Model" (TDM) approach to future U.S. air quality projections (2046-2050) compared to a current-year period (2001-2005), and the interplay between future emission and climate changes. By 2046-2050, there are widespread decreases in future concentrations of carbon monoxide (CO), nitrogen oxides (NO x  = NO + NO 2 ), volatile organic compounds (VOCs), ammonia (NH 3 ), sulfur dioxide (SO 2 ), and particulate matter with an aerodynamic diameter ≤ 2.5 μm (PM 2.5 ) due mainly to decreasing on-road vehicle (ORV) emissions near urban centers as well as decreases in other transportation modes that include non-road engines (NRE). However, there are widespread increases in daily maximum 8-hr ozone (O 3 ) across the U.S., which are due to enhanced greenhouse gases (GHG) including methane (CH 4 ) and carbon dioxide (CO 2 ) under the Intergovernmental Panel on Climate Change (IPCC) A1B scenario, and isolated areas of larger reduction in transportation emissions of NO x compared to that of VOCs over regions with VOC-limited O 3 chemistry. Other notable future changes are reduced haze and improved visibility, increased primary organic to elemental carbon ratio, decreases in PM 2.5 and its species, decreases and increases in dry deposition of SO 2 and O 3 , respectively, and decreases in total nitrogen (TN) deposition. There is a tendency for transportation emission and CH 4 changes to dominate the increases in O 3 , while climate change may either enhance or mitigate these increases in the west or east U.S., respectively. Climate change also decreases PM 2.5 in the future. Other variable changes exhibit stronger susceptibility to either emission (e.g., CO, NO x , and TN deposition) or climate changes (e.g., VOC, NH 3 , SO 2 , and total sulfate deposition), which also have a strong

  19. (How) does sectoral detail affect the robustness of policy insights from energy system models? The refining sector's example

    International Nuclear Information System (INIS)

    Nicolas, Claire; Saint-Antonin, Valerie; Tchung-Ming, Stephane

    2014-01-01

    In this research, we rekindle an old debate by questioning the impact on mitigating policy evaluation of detailing a sub-sector in a global energy-transportation model. We chose the refining sector because it is a relevant case of a sector for which representation widely differs across models and because it offers a unique set of complex joint production in the energy sector. To investigate whether the level of detail in the description of the refinery impacts optimal mitigation options, we take the example of a long-term, national, linear programming based, energy-transport system model (TIMES based). We found that the refinery description used in the energy system model matters when trying to evaluate energy or climate policy applied to the transportation sector. It impacts the policy costs but also the technology trajectories chosen at the optimum. Essentially, the balance between energy efficiency and carbon intensity of transport may be affected by the accuracy of the description of the pivotal refining sector. Consequently, increasing this sector accuracy level should not only be motivated by the wish to gain wider quantitative insights on potential evolution of the energy system but also by the wish to improve the robustness of the model outcomes.

    In September 2005, AFD's Research Department launched a Research Program on Public Private Partnerships with an approach combining economic analysis (contractual incentives, financing of investment, etc.) with a sociological and political approach to regulatory issues. Various case studies have been conducted in different sectors (water and sanitation, power, transport) and countries. This study falls within the above research framework since India - like most major developing countries - has attempted to introduce market forces in its electric power systems. At the same time, growing concern over global climate change has put the spotlight on the need for India to control its emissions of greenhouse gases (GHG). India is currently the world's sixth biggest producer of GHG emissions, but is the second biggest if one considers the rate of augmentation of its emissions. Half of India's total GHG emissions are produced by its power sector, and 70 per cent of electricity is generated by thermal power plants, mainly from coal. Climate change mitigation in the power sector is thus a strategic issue for AFD in India. This study is structured so as to examine the intersection of these two crucial challenges in India by exploring the links between private participation in the power sector in India and the reduction of GHG emissions

  11. Decision making under uncertainty and inertia constraints: sectoral implications of the when flexibility

    1998-01-01

    Current debates on climate mitigation emphasize the role of the inertia of the economic system. Our aim in this paper is to study in more depth how sectorally differentiated inertia impacts on optimal CO 2 -emission abatement policies. Using the STARTS model, we show that optimal abatement levels and costs differ sensibly among sectors. Differential inertia is the critical determinant of this trade-off, especially in the case of a 20-year delay in the action, or in an underestimation of the growth of the transportation sector. In particular, the burden of any additional abatement effort falls on the most flexible sector, i.e. the industry. Debates on mitigation emphasize the role of inertia of the economic system. This paper aims at studying more in depth how sectorally differentiated inertia should influence optimal CO 2 emission abatement policies. Using a two-sector version of STARTS, we show that under perfect expectations, optimal abatement profiles and associated costs differ sensibly between a flexible and a rigid sector (transportation). In a second step, we scrutinize the role of the uncertainty by testing the case of a 20-year delay of action and an underestimated growth of the transportation sector. We do this for three concentration ceilings and we point out the magnitude of the burden which falls on the flexible sector. We derive some policy implications for the ranking of public policies and for incentive instruments to be set up at international level. (Copyright (c) 1998 Elsevier Science B.V., Amsterdam.

    , the paper serves as a case study of the introduction of the motor vehicle in Denmark. Both the supply of goods to the retail outlets (the wholesale side) and the shopping transport are covered. The period covered has seen both a profound restructuring of the grocery sector structure (incl. a reduction...... of the retail shops by some 60%) and a complete change in shopping patterns. The transport demand for grocery shopping has grown 3.8 times, while freight transport of groceries has tripled. Fuel consumption and CO2-emissions are about 2.5 times higher today compared to 1960, whereas NOx-emissions are 3.6 times...

    Transport represents the sector with the fastest growing greenhouse gas emissions around the world. The main global objective is to reduce energy usage and associated greenhouse gas emissions from the transportation sector. For this study it was analyzed the road transportation system from Brasov Metropolitan area. The study was made for the transportation route that connects Ghimbav city to the main surrounding objectives. In this study ware considered four optimization measures: vehicle fleet renewal; building the detour belt for the city; road increasing the average travel speed; making bicycle lanes; and implementing an urban public transport system for Ghimbav. For each measure it was used a mathematical model to calculate the energy consumption and carbon emissions from the road transportation sector. After all four measures was analyzed is calculated the general energy consumption and CO2 reduction if this are applied from year 2017 to 2020.

    The aim of the title analysis is to formulate recommendations to improve the cost-effectiveness of the EIA incentive for the transportation sector in the Netherlands and to reduce the so-called free-rider effect. Attention is paid to several components of means of transportation. Based on available data and interviews with parties involved insight is gained into the decision making process with regard to investment of entrepreneurs. [Dutch] Het doel van de titel-analyse is om aanbevelingen te doen over hoe op kosteneffectieve wijze, i.e. met weinig free-riders, de EIA-regeling voor transportmiddelen kan worden voortgezet. Daarbij is aandacht aan de volgende bedrijfsmiddelen: brandstofverbruiksmeter; cruise control; lichtgewicht brandstoftank; 3d-dakspoiler; zijfender; zijafscherming; neuskegel; en economy meter. Met behulp van onderzoeksgegevens en persoonlijke gesprekken met dealers, vrachtwagen- en busbedrijven en brancheorganisaties is een beeld gevormd over de investeringsbeslissing van ondernemers. Gebleken is dat naast brandstofbesparing andere motieven een grote rol kunnen spelen bij de aanschaf van de bedrijfsmiddelen. Tevens is gebleken dat de markt voor de bedrijfsmiddelen een heterogeen karakter heeft. Daarom is geadviseerd om de markt voor bedrijfsmiddelen op te delen in meer homogene segmenten, te weten: bestelwagens, vrachtwagens en autobussen. Op basis van het aanschafmotief, de terugverdientijd en de penetratiegraad is een inschatting gemaakt van het free-riderpercentage. Tenslotte is advies gegeven omtrent verdere stimulering van de genoemde bedrijfsmiddelen, waarbij het advies voor de meeste bedrijfsmiddelen in de meeste marktsegmenten negatief was. Het advies is grotendeels overgenomen. Een groot aantal bedrijfsmiddelen zijn op de EIA-energielijst voor 2004 niet meer terug te vinden.

    Full Text Available The 2014 World Cup and 2016 Olympics have stimulated competition for investments in the infrastructure for the transportation of passengers, and they have demanded the integration of all modals of the Brazilian transport sector. Why is the transportation sector considered fundamental for the economy success and for mega-events as the World Cup and the Olympics? Objective: Capacity of the country in attracting investments, modernization of all transportation hubs and for the logistics. For reorganization of urban and inter-urban mobility, the country counts with one principal player, the BNDES (Brazilian Development Bank. For the comprehensive time period between the years of 2010-2016, it has an investment perspective in logistics that can practically come close to the R$ 130 Billion (Brazilian Real, of this sum 43% comes from funds of the BNDES, 37% comes from the private sector and approximately 20% from public agencies. Dividing by transportation modals and applied in consolidated projects, sea port sector requirements will take roughly R$ 15 Billion (14% of the total sum; the railroad sector will have approximately the equivalent of R$ 56 Billion (52% of the total sum; the air transport project (TAV will take 31 billion (29% and the road sector with about 36 billion (34%. In summary, the direct participation of the BNDES in projects that integrate planning and actions of the public agencies for the resolution of the structural problems in urban centers is a determining factor for the growth of the country.

  16. Competitiveness in Road Transport

    Borgström, Benedikte; Gammelgaard, Britta; Bruun, Poul

    Road transport is an important sector, connecting time and space of production and consumption. Its market conditions has changed. The EU single market implementation has increased price pressure due to supply of low cost road freight transport from counties with lower cost structures. Changes...... in the market also encourage strategic development of some road hauliers into providers of unique services. Such road haulier strategic development contributes to efficiency and effectiveness in basically all business sectors of EU. Little research is available of such strategic and operational management....... In this paper we will explore that knowledge gap and analyze what value proposition(s) and capabilities can transform potential cost disadvantages of acting in a market that includes both high- and low-cost-country actors? And in conceptual terminology, how are capabilities deployed and developed to construct...

    Ever increasing prosperity and global civilization heralds an increasing demand for communication and transport. The transport sector alone accounts for one quarter of global human greenhouse gas emissions. In the transport sector, road transport alone is responsible for 70%. To help mitigate these emissions, people are advised to take advantage of public transportation systems, on the argument that public transit is more environmentally friendly than private transport. To assess the environm...
