Climate change is a global issue, but actions to mitigate its development are regional. Europe has taken the leadership in the carbon emission policy by introducing the Emissions Trading Scheme (EU ETS), formerly regulated by Directive 2003/87/EC and since 2013 by Directive 2009/29/EC. This new Directive imposes a full auctioning system for allocating CO 2 allowances to the power sector and encourages the use of renewable energy sources. We investigate the economic impacts of the EU ETS on the Italian electricity market using a power generation expansion model. We adopt a technological representation of the energy market that also accounts for power exchanges with foreign countries and we assume that generators operate in different zones connected by interconnections with limited capacity. We study both an oligopolistic and a perfectly competitive behavior of Italian generators and we compare the corresponding outcomes under different EU ETS scenarios. Our analysis shows that, in perfect competition, generators generally invest more than in an oligopolistic framework, but in both market configurations, investments in Italy are mainly concentrated in fossil-fired plants, especially in 2020. This happens also when incentives are given to renewables. The developed models are implemented as complementarity problems and solved in GAMS using the PATH solver. - Highlights: • We evaluate the EU-ETS impacts on the Italian electricity market. • We model different EU-ETS scenarios and energy market organizations. • Generators can invest in new capacity. • Investments in CCGT plants are preferable to those in clean technologies. • Profits depend on market organization and on ETS allowance allocation policies

This study assesses various options for EU (European Union) burden sharing and EU ETS (Emissions Trading System) allocation beyond 2012, based on a sample of policy evaluation criteria and a review of the literature on (1) international and EU burden sharing of future GHG mitigation commitments, and (2) allocation of GHG emission allowances among countries, sectors and emitting installations. It shows that these options score differently with regard to a variety of individual evaluation criteria (such as environmental effectiveness, economic efficiency, social equity or political acceptability), while the overall performance of these options depends on both the selection, interpretation, weighing and adding of these criteria.

Among the publications of CDC Climat Research, 'Tendances Carbone' bulletin specifically studies the developments of the European market for CO 2 allowances. Beside some statistical figures about energy production/consumption and carbon markets, this issue specifically addresses the following points: - EU ETS - MSR negotiations: On May 26, the Environment Committee of the EU Parliament approved the consolidated text for the implementation of the MSR as from 2019, and a placement of back-loaded as well as unused allowances straight into the reserve. A vote in plenary session is scheduled on 7 July. - EU ETS reform: A vote in EU Parliament is scheduled on 7 July to endorse the MSR. The European Commission should propose measures to tackle carbon leakages issues in the six months following the adoption of the MSR. - EU ETS emissions: Emissions under the EU ETS decreased by 4,5 % in 2014, and reached 1,812 Mt CO 2 e

Utslappshandel.se is a one-stop shop for overall information about the EU Emissions Trading Scheme (ETS) as applied in Sweden (the site is available in Swedish and English). It also offers a gateway to the Swedish Emissions Trading Registry (SUS), where companies report their transactions on an ongoing basis and surrender emission allowances once a year. The Swedish Energy Agency is in charge of the Swedish registry. The Swedish Environmental Protection Agency decides on the allocation of emission allowances and is responsible for following up companies' annual reporting on their CO{sub 2} emissions. The EU ETS is expected to cover installations equivalent to approximately 50 per cent of total CO{sub 2} emissions in the EU. In Sweden, it is expected to cover only 40 per cent of emissions, mainly owing to the very low level of fossil electricity production

The impact of the EU ETS on the sectoral innovation system for power generation technologies - Findings for Germany

2010-01-01

This paper provides an overview of early changes in the sectoral innovation system for power generation technologies which have been triggered by the European Emission Trading System (EU ETS). Based on a broad definition of the sector, our research analyses the impact of the EU ETS on the four building blocks 'knowledge and technologies', 'actors and networks', 'institutions', and 'demand' by combining two streams of literature, namely systems of innovation and environmental economics. Our analysis for Germany is based on 42 exploratory interviews with experts in the field of the EU ETS, the power sector, and technological innovation. We find that the EU ETS mainly affects the rate and direction of technological change of power generation technologies within the large-scale, coal-based power generation technological regime, to which carbon capture technologies are added as a new technological trajectory. While this impact can be interpreted as the defensive behaviour of incumbents, the observed changes should not be underestimated. We argue that the EU ETS' impact on corporate CO 2 culture and routines may prepare the ground for the transition to a low-carbon sectoral innovation system for power generation technologies.

Point Climat no. 16 'Applying MiFID to the EU ETS: what are the implications?'

International Nuclear Information System (INIS)

Patay, Magali; Alberola, Emilie

2012-01-01

Among the publications of CDC Climat Research, 'Climate Briefs' presents, in a few pages, hot topics in climate change policy. This issue addresses the following points: The European Union is moving ahead with a proposal to regulate trading in carbon assets under the revised Markets in Financial Instruments Directive (MiFID). This would mean that all trading in such assets, from the European Union Emissions Trading System (EU ETS) to international carbon credits from Kyoto project-based mechanisms eligible for the EU ETS would be covered by the existing EU regulatory framework for financial markets. Allowance spot and derivative markets are set to be supervised by a single oversight authority, and the MiFID and Market Abuse Directive will apply. While this will bring benefits in terms of improved security, transparency and protections for market participants in the carbon market, future challenges for the EU ETS will involve the proper coordination of MiFID with the Auctioning Regulation, and ensuring that the ad hoc treatment of emission allowances is maintained within the MiFID legislation

The EU ETS is a Community-wide scheme established by Directive 2003/87/EC for trading allowances to cover the emissions of greenhouse gases from permitted installations. The first phase of the EU ETS runs from 1 January 2005 to 31 December 2007. Each Member State must develop a National Allocation Plan for the first phase stating: the total quantity of allowances that the Member State intends to issue during that phase; and how it proposes to distribute those allowances among the installations which are subject to the scheme In this paper twelve of the national allocation plans have been analysed and compared to the criteria stated in the EU Directive. The twelve allocation plans analysed are: the Austrian, the Danish, the Finnish, the German, the Irish, the Lithuanian, the Luxembourg, the Dutch, the Swedish, the British and the draft Flemish (Belgium) and Portuguese. Generally most countries have allocated generously to the trading sector. The allocation has often been based on future needs. For most sectors the allocation is higher than current emissions. Many countries will have to make large reductions in the non-trading sector and/or buy credits through JI- and CDM-projects in order to fulfil their commitment according to the EU burden sharing agreement of the Kyoto Protocol. In many of the allocation plans the emission reducing measures in the non-trading sector is poorly described and the credibility of the measures are hard to determine. Two sectors have been analysed in more detail, the energy and the mineral oil refining sectors. Figures presenting allocation vs. current emissions for those sectors are given for those countries where data was available in the allocation plan. The energy sector has been considered to have the best possibilities to pass on costs for the allowances to the consumers and hence the allocation to this sector is often more restricted than the allocation to other sectors. The mineral oil refining sector is more exposed to

The current EU ETS faces a dilemma. To induce low-carbon investments in the power sector, higher carbon prices are needed, while low carbon prices are needed to reduce the risk of carbon leakage and loss of industrial competitiveness. This study analyses the effects and implications of two alternative policy options to address this price dilemma, i.e. (1) splitting the ETS into two separated sector regimes: one more ambitious regime with a relatively high carbon price for the power sector and a less ambitious regime with a relatively low carbon price for the other sectors covered by the EU ETS (called 'industry'), and (2) imposing a carbon tax on power sector emissions additional to a single ETS carbon price for both industry and the power sector. The study uses modelling scenarios and qualitative assessments to analyse the effects and implications of these policy options. It concludes that, in a world with unequal carbon prices, there is a case for differentiating ETS sectoral carbon prices and that the first-best option to achieve this differentiation is to impose a carbon tax on power sector emissions additional to a single ETS carbon price.

This paper presents an alternative approach to a graphical analysis of the interaction of White Certificates with the EU emission trading scheme as the approach of Sorrell et al. (2009a contains the following aspects that require some clarification: first, the issue of a clearer distinction between conventional and alternative energy supply is brought up. Second, the concept of a minimum requirement for energy demanded is discussed. Third, the correlation between demand for energy and demand for energy efficiency measures is displayed in a more intuitive manner. The effects of introducing WCTS and EU ETS into the market setting are then analyzed accordingly. - Highlights: • Interaction of White Certificates with the EU ETS—clarifying a previous approach. • Distinction between conventional and alternative energy within the model setup is discussed. • Concept of a minimum requirement for energy demanded is introduced. • Correlation between demand for energy and energy efficiency is displayed in a more intuitive manner

Costs and Benefits of Stopping the Clock. How Airlines Profit from Changes in the EU ETS

Energy Technology Data Exchange (ETDEWEB)

Nelissen, D.; Faber, J.

2012-12-15

All flights arriving at or departing from EU airports have been included in the EU ETS from the beginning of 2012. Airlines have to surrender allowances for emissions on flights to and from EU airports. A share of the allowances has been issued to the airlines for free, the remainder needs to be acquired at an auction or from the market. In November 2012, the European Commission proposed to exempt intercontinental flights from the EU ETS for 2012, an initiative branded as 'Stopping the Clock'. As a result of this change, airlines on intercontinental routes are likely to experience additional windfall profit, since they have probably anticipated ETS-related expenditures on these routes, which they will now not incur. In addition, all airlines have a windfall profit since they are likely to pass on the value of the free allowances, as has been demonstrated to happen in all other sectors that have received free allowances. This note estimates the windfall profits. The report distinguishes two types of windfall profits: (1) Profits that occur because the opportunity costs of free allowances received for intercontinental flights have been passed on. These windfall profits would also have occurred without the 'stop the clock' exemption. We call them ETS Windfall. (2) Profits that occur because airlines have raised their revenues on intercontinental flights, but will not need to buy allowances either at the auction or from other actors because of the exemption. We call them Stopping the Clock Windfall. Depending on the cost pass through, the total windfall profits range from euro 679 million to euro 1,358 million. About a third of these windfall profits arise from the exemption of intercontinental flights. EU airlines are expected to reap the largest share of the windfall due to the change in regulation (55%), followed by US airlines (13%).

Point Climat no. 12 'The EU ETS carbon price: To intervene, or not to intervene?'

International Nuclear Information System (INIS)

Sartor, Oliver

2012-01-01

Among the publications of CDC Climat Research, 'Climate Briefs' presents, in a few pages, hot topics in climate change policy. This issue addresses the following points: Extraordinary economic circumstances and interactions between climate and energy policies have meant that the EU's industrial CO 2 emissions are now much lower than expectations when the EU ETS' emissions reduction objectives were set. Since this has reduced the demand for EU ETS emissions allowances relative to a fixed supply, the price of allowances has fallen significantly. Although this is a normal market reaction, it has led to demands for intervention in the market to support the price. This brief discusses this issue. It concludes that, above all, a robust and effective CO 2 price signal requires a more credible commitment on the part of policy-makers to an ambitious post-2020 emissions budget. Barring that, if any intervention is to occur, the way it is 'framed' will be extremely important for the precedent it sets

Calel, Raphael; Dechezlepretre, Antoine

2013-01-01

Among the publications of CDC Climat Research, 'Tendances Carbone' bulletin specifically studies the developments of the European market for CO 2 allowances. This issue addresses the following points: The EU ETS is the main instrument of European climate policy, and many policy-makers envisage it as a driving force of the EU's transition to a low-carbon economy. By putting a price on emissions, the scheme is expected to encourage heavy polluters to develop new low-carbon technologies. At first glance it is encouraging to notice, then, that patenting for low-carbon technologies has surged in Europe since 2005. When analysing new data we find compelling evidence that the EU ETS has indeed encouraged regulated companies to develop new low-carbon technologies, but this effect is concentrated among too few companies to account for the surge in low-carbon patenting

The role of auctions and forward markets in the EU ETS: counterbalancing the cost-inefficiencies of combining generous allocation with a ban on banking

Energy Technology Data Exchange (ETDEWEB)

Ehrhart, K.M.; Hoppe, C.; Schleich, J.; Seifert, S.

2005-07-01

From an analysis of the available national allocation plans for the first period (2005-2007) of the EU emissions trading scheme (EU ETS), it can be inferred that (i) the total allocation to installations covered under the EU ETS is rather generous and (ii) most EU Member States ban the transfer of allowances (banking) into the second period (2008-2012). In this article, we explore the cost-efficiency issues associated with such a generous allocation of allowances to the trading sectors in combination with the ban on banking. It is argued that allocation to the trading sectors is higher than implied by a cost-minimization approach. Moreover, due to the reduced level of flexibility, a ban on banking increases overall compliance costs. In addition, the results of a simulation game conducted with real company participants and with a student control group suggest that a generous primary allocation in the first phase combined with a ban on banking also leads to a cost-inefficient choice of abatement measures within periods. The results of the simulations are also consistent with the conjecture that forward markets and auctioning off a part of the total quantity of allowances result in more reliable price signals and most cost-efficient outcomes.

Causes of the EU ETS price drop: Recession, CDM, renewable policies or a bit of everything?—New evidence

International Nuclear Information System (INIS)

Koch, Nicolas; Fuss, Sabine; Grosjean, Godefroy; Edenhofer, Ottmar

2014-01-01

The price of EU allowances (EUAs) in the EU Emissions Trading Scheme (EU ETS) fell from almost 30€/tCO 2 in mid-2008 to less than 5€/tCO 2 in mid-2013. The sharp and persistent price decline has sparked intense debates both in academia and among policy-makers about the decisive allowance price drivers. In this paper we examine whether and to what extent the EUA price drop can be justified by three commonly identified explanatory factors: the economic recession, renewable policies and the use of international credits. Capitalizing on marginal abatement cost theory and a broadly extended data set, we find that only variations in economic activity and the growth of wind and solar electricity production are robustly explaining EUA price dynamics. Contrary to simulation-based analyses, our results point to moderate interaction effects between the overlapping EU ETS and renewable policies. The bottom line, however, is that 90% of the variations of EUA price changes remains unexplained by the abatement-related fundamentals. Together, our findings do not support the widely-held view that negative demand shocks are the main cause of the weak carbon price signal. In view of the new evidence, we evaluate the EU ETS reform options which are currently discussed. - Highlights: • We examine whether abatement-related fundamentals justify the EU ETS price drop. • 90% of the variations of EUA price changes remain unexplained. • Variations in economic activity are robustly explaining EUA price dynamics. • Price impact of renewable deployment and international credit use remains moderate. • Reform options are evaluated in the light of the new findings

Does EU ETS lead to emission reductions through trade? The case of the Swedish emissions trading sector participants

International Nuclear Information System (INIS)

Sandoff, Anders; Schaad, Gabriela

2009-01-01

The first trading period of the European Emissions Trading Scheme (EU ETS) has recently come to an end. The experiences of the actors in the trading sector will be of great importance in evaluating the aim and direction of this 'Grand Policy Experiment'. This paper gives an account of the attitudes and actions of the companies included in the Swedish emissions trading sector after about 15 months of experience with the system. The data are based on a study commissioned by the Swedish Environmental Protection Agency, and is a comprehensive survey that encompasses all companies operating installations included in the Swedish Emission Trading Registry. However, the results point in a somewhat disquieting direction. Although the Swedish companies have shown significant interest in reducing emissions, this survey indicates that this is done without close attention to the pricing mechanism of the market-based instruments. If this praxis is widespread within the European trading sector, it can have a serious negative effect on the efficiency of the system.

Border tax adjustments and the EU-ETS. A quantitative assessment

International Nuclear Information System (INIS)

Manders, T.; Veenendaal, P.

2008-10-01

If the EU stands alone in adopting climate policy and imposes a strict emissions ceiling, competitiveness of EU energy-intensive sectors will be affected negatively. Relocation of EU energy-intensive firms to countries with a lax regime also leads to carbon leakage. However, when use is made of the opportunities of the Clean Development Mechanism these impacts are very modest. Border tax adjustments (BTAs) to 'level the playing field' between domestic and foreign producers may be considered to address the concerns about both competitiveness and carbon leakage. It is far from clear whether these measures are WTO-proof. Simulations show that both an import levy and an export refund restore competitiveness to a certain extent. BTAs may lower the costs for energy-intensive sectors, but induce higher costs for other sectors. This paper uses a general equilibrium model to quantify and assess the implications of a number of policy scenarios

Governance of CO2 markets: Lessons from the EU ETS

International Nuclear Information System (INIS)

Perthuis, Christian de; Trotignon, Raphael

2014-01-01

The European emissions trading scheme (EU ETS) is the centerpiece of Europe's climate policy. The system has been undermined variously by the weakness of its regulation, an undesirable overlap with other public policies and the far-reaching economic and financial crisis that caused the market price of allowances to plunge. This article attempts to identify the conditions for making the coming years of the EU ETS a success. It draws historical lessons from the eight years the scheme has been in operation, and then presents the various interventions by the public authorities currently under discussion in order to revive the market. Finally, the article proposes to draw lessons from monetary policy by outlining what might be the mandate of an Independent Carbon Market Authority, with responsibility for the dynamic management of the supply of allowances, and whose main mission would be to ensure the optimal linkage between the different temporal horizons of the climate strategy. This article could provide important lessons for schemes developing in the rest of the world, especially in South Korea or in China. - Highlights: • History suggest that ex ante expectations tend to overestimate the constraint. • Economic conditions, policy overlaps, and Kyoto credits cause the current weakness. • “Set aside” or “backloading” does not resolve structural issues. • Changing/extending the reduction target is necessary but not sufficient. • An independent authority could ensure the credibility of the constraint over time

Point Climat no. 25 'Auction revenues in EU ETS Phase 3: a new public resource'

International Nuclear Information System (INIS)

Chevaleyre, Guillaume; Berghmans, Nicolas

2013-01-01

Among the publications of CDC Climat Research, 'Climate Briefs' presents, in a few pages, hot topics in climate change policy. This issue addresses the following points: As from 1 January 2013, auctions will become the main mode for distributing CO 2 allowances within the EU ETS. By 2020, almost one billion EUAs will be sold every year and generate income for Member States. Although sales of Phase 3 allowances have begun, uncertainty still surrounds the total amount of allowances to be auctioned. In particular, benchmark free allocations, the potential review of the auction timetable and the exemption of international flights from the EU ETS will impact the final amounts auctioned and the EUA price. These factors will affect the final auction revenues of each Member States differently. Government authorities will need to take account of the variability of this new financial resource

Interaction of the EU ETS and national climate policy instruments – Impact on biomass use

Kautto, N.; Arasto, A.; Sijm, J.; Peck, P.

Policy-makers apply multiple policy instruments simultaneously in the climate and energy policy field at both EU and Member State levels. This creates interactions between instruments that can be complementary and synergistic but also conflicting. This article focuses on the interactions of climate policy instruments and their impact on biomass use. The objectives are to examine interactions of the EU Emissions Trading System (EU ETS) with the main national climate policy instruments and to identify the influence of these on biomass use. The work draws experiences from seven EU countries (Austria, Finland, Germany, the Netherlands, Poland, Sweden and the United Kingdom), with a special focus on Finland and Sweden. The analysis explores the effects of policy interactions and is based on an examination of literature, and interviews with biomass experts in research, industry and policy spheres. Results indicate that the combined effects of climate policy instruments have a tangible impact on biomass use, whereas the causal links to the EU ETS are difficult to assess separately. Policy impacts found include increased competition for biomass resources, changes in fuel mixes and a contribution to upward pressure on wood prices. Differences in these effects are linked to differing national policy mixes and energy-carrier portfolios – an example being the relative differences in the importance of peat to the energy mix in Finland and Sweden. Analysis and comparison of the effects in the selected countries can yield insight on how to improve the design of policy interventions that impact biomass use. This study confirms the importance of identifying interactions between policy instruments so as to recognise – and manage – synergies and conflicts. The development of more synergistic and coordinated policy instrument mixes would also be beneficial for the bioenergy field. -- Highlights: ► Combined effects of climate policy instruments have a tangible impact on biomass

Causalities between CO2, electricity, and other energy variables during phase I and phase II of the EU ETS

The topic of this article is the analysis of the interplay between daily carbon, electricity and gas price data with the European Union Emission Trading System (EU ETS) for CO 2 emissions. In a first step we have performed Granger causality tests for Phase I of the EU ETS (January 2005 until December 2007) and the first year of Phase II of the EU ETS (2008). The analysis includes both spot and forward markets - given the close interactions between the two sets of markets. The results show that during Phase I coal and gas prices, through the clean dark and spark spread, impacted CO 2 futures prices, which in return Granger caused electricity prices. During the first year of the Phase II, the short-run rent capture theory (in which electricity prices Granger cause CO 2 prices) prevailed. On the basis of the qualitative results of the Granger causality tests we obtained the formulation testable equations for quantitative analysis. Standard OLS regressions yielded statistically robust and theoretically coherent results. (author)

EU Emission Trading - better job second time around?

The EU Emission Trading Scheme (EU ETS) for CO 2 -emissions from energy and industry installations reflects a paradigm shift towards market-based instruments for environmental policy in the EU. The centerpieces of the EU ETS are National Allocation Plans (NAPs), which individual Member States (MS) design for each phase. NAPs state the total quantity of allowances available in each period (ET-budget) and determine how MS allocate allowances to individual installations. The NAPs thus govern investments and innovation in energy efficient technologies and the energy sector. In terms of distribution, they predetermine winners and losers. In this paper we analyze and evaluate 25 NAPs submitted to the European Commission (EC) for phase 2 (2008-2012) of the EU ETS. At the macro level, we assess whether the submitted ET-budgets are stringent, and whether they imply a cost-efficient split of the required emission reductions between the EU ETS sectors (energy and industry) and the remaining sectors (transportation, tertiary and households). Comparing the submitted ET-budgets with those already approved by the EC suggests that the EC's decisions significantly improved the effectiveness and economic efficiency of the EU ETS. But given the high share of Kyoto Mechanisms companies are allowed to use, the EU ETS is unlikely to require substantial emission reductions within the EU. At the micro level, we assess (across countries and phases) the allocation methods for existing and new installations, for closures and for clean technologies. A comparison of the NAPs for the second phase and the first phase (2005-2007) provides insights into the (limited) adaptability and flexibility of the scheme. The findings provide guidance for the future design of the EU ETS and applications to other sectors and regions

Power prices in EU countries have increased significantly since the European Emissions Trading Scheme (EU ETS) became effective on 1 January 2005. This suggests that these increases in power prices are due to this scheme, in particular the pass-through of the costs of EU allowances (EUAs) to cover the CO2 emissions of eligible installations. In all sectors, however - including the power sector - eligible installations have usually received almost all of their needed allowances for free during the first phase of the EU ETS (2005-07). In several EU countries, the coincidence of the increases in power prices and the implementation of the EU ETS has raised questions, and sometimes fierce political debate, on whether power producers have indeed passed through the costs of freely allocated CO2 allowances to electricity prices, and to what extent the increase in these prices can be attributed to this pass-through or to other factors. In addition, it has raised discussions on whether - and to what extent - the supposed passing through of these costs has led to additional profits for power producers, that is, the so-called 'windfall profits' induced by the EU ETS. Finally, the supposed ETSinduced increases in power prices and generators' profits has raised concerns affecting the legitimacy of the present EU ETS, including concerns regarding its impact on the international competitiveness of some powerintensive industries, the purchasing power of electricity end-users such as small households or, more generally, the distribution of social welfare among power producers and consumers. As a result, in several countries policy makers and stakeholders have suggested a variety of options to address these concerns, including changing the emissions trading allocation system, taxing windfall profits or controlling market prices of EU carbon allowances, electricity or both. Against this background, the objectives of this chapter include: (a) To analyse empirically the trends in power

Contribution of Eu ions on the precipitation of silver nanoparticles in Ag-Eu co-doped borate glasses

Graphical abstract: - Highlights: • Silver nanoparticles are precipitated from the borate glasses during the melting process without any further heat treatment. • The reduction of Eu 3+ ions to Eu 2+ ions is presented in this material. • The intensity of Ag + luminescence. • The introduction of Eu ions accelerated the reaction between Eu 2+ ions and silver ions inducing the silver clusters formation. - Abstract: Ag + doped sodium borate glasses with different Eu ions concentration were prepared by the melt-quenching method. The absorption at about 410 nm which was caused by the surface plasmon resonance (SPR) of Ag nanoparticles (NPs) is promoted with increasing of Eu ions concentration. Meanwhile, the luminescent spectra showed that the emission intensity of Ag + decreased while that of the Ag aggregates increased simultaneously. The results indicated that the Ag ions intend to form the high-polymeric state such as Ag aggregates and nanoparticles with increasing of europium ions. Owing to the self-reduction of Eu 3+ to Eu 2+ in our glass system, it revealed that Ag + has been reduced by the neighboring Eu 2+ which leads to the formation of Ag aggregates and the precipitation of Ag NPs in the matrix. In addition, energy transfer (ET) process from Ag + /Ag aggregates to the Eu 3+ was investigated for the enhancement of Eu 3+ luminescence

Introducing short term flexibility in the EU ETS to assure its long-term credibility: a multi-criteria analysis of policy options. Climate Report no. 45

Desai, Zuheir; Alberola, Emilie; Berghmans, Nicolas

2014-07-01

It is now well established that the European Union Emissions Trading Scheme (EU ETS) needs to be reformed. After more than 18 months of discussions, the EU Commission disclosed, in its communication published in January 2014 on 'A policy framework for climate and energy in the period from 2020 to 2030', its legislative proposal of a market stability reserve (MSR) in the EU ETS. This measure, that should be implemented from the next compliance period (2021-2028) onwards, would reduce the surplus of allowances growing since 2008 and improve the ETS's resilience to external shocks by automatically adjusting the supply of allowances to be auctioned. The operation of this MSR would be determined by predefined rules that, once agreed on, leave no discretion to either the Commission or Member States. The choice of the EU Commission to introduce a reserve in the EU ETS is very innovative even if other emissions trading schemes have already introduced a reserve in their design. Initial discussions began in March and April 2014 in the European Parliament and Council and the question of whether the MSR really improves the functioning of the EU ETS in the long term is still being debated. What other structural mechanism would be better suited in improving the long-term effectiveness of the EU ETS? To help in the decision making process, this report presents a multi-criteria analysis. Without prejudging their political support, five policy options have been evaluated that would introduce some flexibility in the EU ETS and potentially ensure its long-term credibility: an auction reserve price, permit supply rules that target a certain corridor of surplus (market stability reserve), permit supply rules that target economic activity, permit supply rules that target overlap with other energy policies and a rolling emissions cap. The assessment of these five policy options was based on a criteria tree and on the EU ETS experts' panel's votes that expressed

After 2012, the third phase of the EU Emissions Trading Scheme (EU ETS) that lasts until 2020 will come into effect. New in this phase is the European harmonized rights issue in which for each sector the basic emission rights and the issue of those rights is fixed. Also, a significantly larger proportion of those rights will be auctioned. For the Netherlands the third phase of the EU ETS means that the emissions of companies in 2020 should be reduced by 21% compared to 2005. This involves costs for these companies, including the purchase of rights or taking technical and organizational measures to cut CO2 emissions. This study provides insight into the magnitude of these costs, who will bear the cost and the total direct income effects on businesses, consumers and government. [nl

Etude Climat no. 39 'More than 800 agricultural and agri-food sites affected by the EU ETS'

Foucherot, Claudine; Bellassen, Valentin

2013-01-01

Among the publications of CDC Climat Research, 'Climate Reports' offer in-depth analyses on a given subject. This issue addresses the following points: Agriculture accounts for 9% of Europe's anthropogenic emissions, counting only emissions of methane and nitrous oxide from cattle, crops and pasture. These emissions have two characteristics making their inclusion in the European Emission Trading Scheme (EU ETS) difficult: they are diffuse and depend on a range of fairly complex pedo-climatic factors. Taking into consideration the whole of the agricultural sector, including upstream activities such as production of fertilizer, phyto-sanitary products, animal feed etc., as well as downstream emissions, dominated by the agri-food sector, and also emissions linked to energy consumption by farming installations, the sector's emissions contribution increases considerably. Within this expanded scope, some emissions sources are included in the EU ETS - mainly agri-food industries, but also producers of fertilizer, heated greenhouses and knackers' yards. Even if the proportion of the agricultural and agri-food sector's emissions covered by the emissions trading scheme is minimal, with just 1.5% of all emissions falling within the scope of the EU ETS, more than 800 industrial sites are covered, accounting for 8% of installations covered by the system. The agricultural and agri-food sector are among the net beneficiaries of the EU ETS in the first two phases (2005-2012), with a surplus of 33 million allowances over the period 2008-2011. This surplus, combined with gains from trading in allowances and credits, represents an estimated asset of 495 million euros. Although it has not been fully exploited on the market, this asset largely exceeds the cost of transactions associated with emissions monitoring, reporting and verification (MRV) procedures and compliance work, which is estimated at 30 million euros over the same period. The emission trading scheme has therefore been

2009-11-15

In 2013, the third trading period of the EU emission trading scheme (EU ETS) will start. With a few exceptions, no free allocation of emission allowances is foreseen in this third trading period for the emissions related to the production of electricity. These emission allowances will be auctioned. For other emissions, transitional free allocation of emission allowances is envisioned. This free allocation will be based on Community wide allocation rules that will, to the extent feasible, be based on ex-ante benchmarks. In 2013, the free allocation is 80% of the quantity determined via these rules, going down to 30% in 2020. An exception is made for activities that are deemed to be exposed to a significant risk of carbon leakage. These activities will receive an allocation of 100% of the quantity determined via the rules. The benchmarks should in principle be calculated for products, i.e. a specific performance per unit productive output, to ensure that they maximize greenhouse gas reductions throughout each production process of the sectors concerned. In this study for the European Commission, a blueprint for a methodology based on benchmarking is developed to determine the allocation rules in the EU ETS from 2013 onwards. In case where benchmarking is not regarded feasible, alternative approaches are suggested. The methodology allows determining the allocation for each EU ETS installation eligible for free allocation of emission allowances. The focus of this study is on preparing a first blueprint of an allocation methodology for free allocation of emission allowances under the EU Emission Trading Scheme for the period 2013-2020 for installations in the refinery industry. The report should be read in conjunction with the report on the project approach and general issues.

Carbon futures and macroeconomic risk factors. A view from the EU ETS

International Nuclear Information System (INIS)

Chevallier, Julien

2009-01-01

This article examines the empirical relationship between the returns on carbon futures - a new class of commodity assets traded since 2005 on the European Union Emissions Trading Scheme (EU ETS) - and changes in macroeconomic conditions. By using variables which possess forecast power for equity and commodity returns, we document that carbon futures returns may be weakly forecast on the basis of two variables from the stock and bond markets, i.e. equity dividend yields and the 'junk bond' premium. Our results also suggest that the forecast abilities of two variables related to interest rates variation and economic trends on global commodity markets, respectively the U.S. Treasury bill yields and the excess return on the Reuters/CRB Index, are not robust on the carbon market. This latter result reinforces the belief that the EU ETS is currently operating as a very specific commodity market, with distinct fundamentals linked to allowance supply and power demand. The sensitivity of carbon futures to macroeconomic influences is carefully identified following a sub-sample decomposition before and after August 2007, which attempts to take into account the potential impact of the 'credit crunch' crisis. Collectively, these results challenge the market observers' viewpoint that carbon futures prices are immediately correlated with changes in the macroeconomic environment, and rather suggest that the carbon market is only remotely connected to macroeconomic variables. The economic logic behind these results may be related to the fuel-switching behavior of power producers in influencing primarily carbon futures price changes. (author)

Policy options for carbon taxation in the EU

International Nuclear Information System (INIS)

Laurent, Eloi; Le Cacheux, Jacques

2010-06-01

Even though the EU clearly leads the global fight against climate change and despite the additional reduction in emissions due to the global crisis and European recession, the ambitious objectives flagged in the '20-20-20 by 2020' strategy and 'climate-energy package' are probably out of reach if a more resolute and consistent policy of carbon taxation is not rapidly put in place. First, the EU is not as 'virtuous' as it may seem, and shows signs of a 'fatigue' in mitigating climate change; this is explained by the weak incentive structure of current climate institutions, due to both narrow coverage and insufficient stringency of the European 'Emission Trading Scheme' (ETS) - the European 'carbon market'-, and to excessive reliance on emission standards combined with weak energy taxation. Fears of losing competitiveness are a major argument against imposing a higher carbon price on industries, feeding tax competition both within the EU and vis-a-vis the rest of the world. Though not fully satisfactory, the Commission's recent proposal (a revision of the 2003 energy taxation directive introducing floors on national excises based on carbon content) would help solving the intra-EU conundrum. Alternatively, an extension of the EU ETS to households and the transport sector via the 'upstream' inclusion of fossil fuel dealers would also be a feasible solution. In order to answer the 'carbon leakage' argument and to send appropriate price signals to European consumers on extra-EU imports, a border adjustment mechanism - carbon levy or inclusion of importers into the EU ETS - is also necessary. Ultimately though, in order to make sure that economic agents face a uniform carbon price, a generalized carbon tax, in the form of a European 'Carbon Added Tax' (ECAT), would be the most effective instrument in the fight against climate change, as well as the pillar of a thorough tax

2012-01-01

Among the publications of CDC Climat Research, 'Climate Reports' offer in-depth analyses on a given subject. This issue addresses the following points: CO 2 emissions from international aviation, which accounted for 2% of global emissions in 2009, are not currently capped by any international agreement. The inclusion of the aviation sector in the European Union Emissions Trading Scheme (EU ETS) from January 1 2012 onwards represents a first step towards the implementation of emission reduction regulations based on an emissions trading scheme After the gradual extension of the scope of the EU ETS to new countries since 2005, the European Commission is now assimilating around 5,400 airlines that operate in Europe, two-thirds of which are non-European, into the EU ETS to join the energy generation and manufacturing industries. This European Union's decision assigns quantified CO 2 emission reduction targets to airlines: a 3% reduction in 2012 compared with average CO 2 emissions for the sector between 2004 and 2006, then a 5% reduction between 2013 and 2020. In the short term, the inclusion of the aviation sector in the EU ETS should have an impact on the scheme. Indeed, the aviation sector is expected to represent a new source of demand for allowances. Based on the assumption of an average 2.5% increase in annual emissions between 2012 and 2014, and then of an increase of 2% over the period between 2015 and 2020, airlines would create a shortfall of 382 MtCO 2 between 2012 and 2020. The limited use of Kyoto credits to help them comply offers a maximum import potential of almost 65 MtCO 2 between 2012 and 2020. This inclusion is a test of the EU's proactive policy, which involves encouraging other countries to define their own climate policy, without breaching international law,. The potential exemption of airline operators from emitter countries that introduce equivalent regulations would be a success for the European policy. For the time being, the reaction of some

Carbon market becomes increasingly popular as a cost-effective instrument to mitigate CO_2 emissions. However, its construction is a learning-by-doing process, and needs consistent regulatory updates in order to deliver optimal effects. This paper uses the event study method to assess the impacts of different policy adjustments on the EUA returns in the European Union Emissions Trading Scheme (EU ETS) since 2005. Comparing to existing studies that focus on the impact of a single policy, this paper provides a complementary reference on if and to what extent policy adjustments can impact the carbon prices by classifying all regulatory update events into six categories. Its key findings are as follows. First, aggregate impacts of total 50 events studied are low while impacts of events having underlying negative impacts are higher than those having underlying positive impacts. Second, 24 events have significant impacts on EUA returns and are coherent to their theoretical impacts (except one event). Third, events having negligible impact on EUA returns are those that are announced not for the first time or those having no impact on CO_2 quotas supply and demand. Finally, there are different impact patterns: some events have different impacts on short-end and long-end carbon prices. - Highlights: • Impacts of policy adjustments in the EU ETS on carbon price are investigated. • Aggregate impacts of total 50 events studied are low. • Policy adjustments having underlying negative impacts have a higher impact. • Events that are announced for the first time are apt to have significant impact. • There are different impact patterns of events on EUA spot and futures returns.

The study analyses options for further development of the EU Emissions Trading Scheme (EU-ETS) after 2012. The first analysis focuses on the effects of the EU-ETS on companies, power prices, competitiveness and employment. It is followed by an analysis of overlaps or lacking coverage regarding the climate policies EU-ETS, Eco-Tax (Oekosteuer) resp. Energy Tax, the Renewable Energy Sources Act and the Combined Heat and Powert Act. These instruments are analysed with regards to their coherence. As a next step, the national allocation plans of France, The Netherlands, the United Kingdom and Poland are evaluated and recommendations are developed. Best practice recommendations for further developing the EU-ETS after 2012 both at the European and the national level are developed from the comparison of these European national allocation plans. Finally, design features of certificate systems relevant for international linking of such systems are addressed. In the analysis such design features are identified and approaches for problems potentially arising when certificate systems are linked, are developed. (orig.)

Three computable general equilibrium models are used to estimate the economic implications of a stylized version of EU climate policy. If implemented at the lowest possible cost, the 20% emissions reduction would lead to a welfare loss of 0.5-2.0% by 2020. Second-best policies increase costs. A policy with two carbon prices (one for the ETS, one for the non-ETS) could increase costs by up to 50%. A policy with 28 carbon prices (one for the ETS, one each for each Member State) could increase costs by another 40%. The renewables standard could raise the costs of emissions reduction by 90%. Overall, the inefficiencies in policy lead to a cost that is 100-125% too high. The models differ greatly in the detail of their results. The ETS/non-ETS split may have a negligible impact on welfare, while the renewables standard may even improve welfare. The models agree, however, that the distortions introduced by total EU package imply a substantial welfare loss over and above the costs needed to meet the climate target. The marginal, total and excess costs reported here are notably higher than those in the impact assessment of the European Commission. (author)

Tendances Carbone no. 73 'Reforming the EU ETS, Act I: pushing back the allowance auction timetable'

International Nuclear Information System (INIS)

Alberola, Emilie

2012-01-01

Among the publications of CDC Climat Research, 'Tendances Carbone' bulletin specifically studies the developments of the European market for CO 2 allowances. This issue addresses the following points: On July 25 2012, the European Commission presented its first reform to re-calibrate the supply of allowances in EU ETS, via two proposals aimed at amending the ETS Directive and reviewing the auction regulations, in order to alter the auctioning timetable during the period between 2013 and 2020, with no legal risk. The aim is to withdraw a certain amount of the allowances auctioned in 2013, 2014 and 2015, in order to reintroduce that amount after 2018

The evolution of emissions trading in the EU. Tensions between national trading schemes and the proposed EU directive

2003-12-01

The EU is pioneering the development of greenhouse gas emissions trading, but there is a tension between the 'top-down' and 'bottom-up' evolution of trading schemes. While the Commission is introducing a European emissions trading scheme (EU ETS) in 2005, several member states have already introduced negotiated agreements that include trading arrangements. Typically, these national schemes have a wider scope than the proposed EU directive and allow firms to use relative rather than absolute targets. The coexistence of 'top-down' and 'bottom-up' trading schemes may create some complex problems of policy interaction. This paper explores the potential interactions between the EU ETS and the negotiated agreements in France and UK and uses these to illustrate some important generic issues. The paper first describes the proposed EU directive, outlines the UK and French policies and compares their main features to the EU ETS. It then discusses how the national and European policies may interact in practice. Four issues are highlighted, namely, double regulation, double counting of emission reductions, equivalence of effort and linking trading schemes. The paper concludes with some recommendations for the future development of UK and French climate policy

The impact of the EU emissions trading scheme on the price of electricity in the Netherlands

International Nuclear Information System (INIS)

Sijm, J.P.M.

2004-02-01

In this paper a specific aspect of the proposed EU Emissions Trading System (EU ETS) is discussed, namely the potential impact of the EU ETS on the price of electricity in the Netherlands and, hence, the potential implications for Dutch power producers and consumers. It shows that the EU ETS may lead to a significant increase in the price of electricity in the Netherlands (and other EU Member States), depending on the marginal costs of emissions trading (i.e. the price of an emission allowance), the emission factor of the marginal production technology to generate electricity, and the extent to which the costs of emissions trading will be passed on to the end-users of electricity. If, for one reason or another, these costs will not be passed on to power consumers, it will have an adverse impact on overall efficiency from both an energy and economic point of view. On the other hand, if - as expected - these costs are indeed passed on to end-users of electricity, it will benefit power producers (mainly owing to the economic rent of allocating emission allowances for free), while it will harm those energy-intensive industries that, in turn, are not able to pass the higher electricity costs to their customers (resulting in a loss of economic production and income). To some degree, these effects can be best avoided by auctioning emission allowances mandatory throughout the EU ETS and using the auction revenues to reduce the overall level of taxation and social premiums in order to improve the overall competitiveness of domestic industries and to (partly) compensate power consumers for the ET-induced increase in the price of electricity

How competitive are EU electricity markets? An assessment of ETS Phase II

Castagneto-Gissey, Giorgio

This paper studies the interactions between electricity and carbon allowance prices in the year-ahead energy markets of France, Germany, United Kingdom and the Nordic countries, during Phase II of the EU ETS. VAR and Granger-causality methods are used to analyze causal interfaces, whereas the volatility of electricity prices is studied with basic and asymmetric AR-GARCH models. Among the main results, the marginal rate at which carbon prices feed into electricity prices is shown to be ca. 135% in the EEX and Nord Pool markets, where electricity and carbon prices display bidirectional causality, and 109% in the UK. Therefore, generators in these markets internalized the cost of freely allotted emission allowances into their electricity prices considerably more than the proportionate increase in costs justified by effective carbon intensity. Moreover, electricity prices in France are found to Granger-cause the carbon price. This study also shows how European electricity prices are deeply linked to coal prices among other factors, both in terms of levels and volatility, regardless of the underlying fuel mix, and that coal was marginally more profitable than gas for electricity generation. EU policies aimed at increasing the carbon price are likely to be crucial in limiting the externalities involved in the transition to a low-carbon system. - Highlights: • The interactions between electricity and carbon prices during Phase II are investigated. • This work also studies the determinants of EU electricity price levels and volatilities. • Nord Pool, APX UK and EEX carbon cost pass-through rates emphasize low electricity market competitiveness. • Powernext electricity prices Granger-cause the Phase II carbon price. • Coal was marginally more profitable than gas during Phase II

In 2009, the EU climate and energy package with targets for 2020 (the so-called 20-20-20 targets) were formulated. For the period after 2020, however, there are no legally binding targets at the EU level, except for a decreasing ETS cap which will not be sufficient in light of the ambition for 2050. This leads to uncertainty for market players, as project lead times are long and high upfront investments need to deliver returns well beyond 2020. In its Green Paper on a 2030 framework for climate and energy policies, the European Commission recognised the need for clarity regarding the post-2020 policy framework. Currently under discussion is whether the approach for 2020 should be continued towards 2030 in the form of three more stringent targets or that other approaches would be more appropriate. Within this context, the Dutch Government asked PBL Netherlands Environmental Assessment Agency and Ecofys for advice. PBL and Ecofys have subsequently analysed possible options for an EU policy framework for 2030 that will steer towards a low-carbon economy by 2050 in a cost-effective way.

Total neutron cross-section measurements have been carried out for natural Eu and its stable isotopes in the energy range from 3 meV to 1 eV. The measurements were performed using two time-of-flight spectrometers installed in front of two of the horizontal channels of the ET-RR-1 reactor. The following results have been obtained: sigmasub(a) (/sup 151/Eu) = (9180 +- 150) b at 0.0253 eV, sigmasub(s) (/sup 153/Eu) = (375 +- 20) b at 0.0253 eV, sigmasub(d) (Eu) = (4600 +- 120) b at 0.0253 eV. The contribution of the resonance to the total neutron cross-sections, in the thermal region, was calculated using the single-level Breit-Wigner formula.

Among the publications of CDC Climat Research, 'Climate Reports' offer in-depth analyses on a given subject. This issue addresses the following points: Since 2005, 1,453 power and combined heat and power (CHP) generation plants have participated in the European Union Emission Trading Scheme, or EU ETS, which requires them to comply with an annual CO 2 emission cap set by the European Commission. Thermal power plants that use coal (bituminous coal, lignite, and other kinds of coal) and natural gas as their primary fuel jointly account for 86% of the generation capacity included in the EU ETS. There are twice as many gas-fired power plants as coal-fired ones, with 671 gas-fired power plants compared with 352 coal-fired ones

Non-ETS emission targets for 2030. Indication of emission targets for the Netherlands and other EU Member States under the European Effort Sharing Decision

. Our sensitivity analysis suggests that reduction targets for the wealthier Member States are not very sensitive to the assumptions made about the minimum reduction target for the least wealthy Member State. The effect of an increase in the overall EU reduction target is larger. We found that an increase in the reduction target from 40% to 45%, while keeping the minimum reduction target constant, would lead to an increase of about 11% in the reduction target for the wealthiest Member States (for the Netherlands this would be about 9%). For the Netherlands, we found non-ETS emission reduction targets for 2030 of 40% (scenario A) and 43% (scenario B), compared to 2005 emission levels. This corresponds to a respective non-ETS emission budget of 76 and 72 Mt CO2 equivalents by 2030. These emission budgets should however be considered as mere indications. When taking into account the enlarged scope of the ETS from 2013 onwards, the 2030 emission budgets are expected to be somewhat lower. For the Netherlands, the effect could be about 1 Mt CO2 equivalent.

Free allocation in the European Emissions Trading System (EU ETS): identifying efficient mechanisms through to 2030

International Nuclear Information System (INIS)

Jalard, Matthieu; Alberola, Emilie

2015-11-01

In a world with asymmetrical climate policies, the conclusions of the European Council of October 2014 agreed on continuing the allocation of free CO 2 emissions allowances beyond 2020 to industrial sectors in the EU ETS. This statement has been confirmed in the European Commission's proposal to revise EU ETS directive for phase IV disclosed in July 2015. The stated objective is to ensure that the most efficient industrial installations do not face undue carbon costs which would lead to carbon leakages. Furthermore, free allocations should not undermine the incentive to cut CO 2 emissions, lead to distortions or windfall profits and reduce the auctioning share of allowances. From 2013 to 2020, the allocation of free allowances has been defined according to harmonized European rules based on benchmarks (carbon intensity targets) and historical output adjusted to the free allocation cap by applying the Cross-Sectoral Correction Factor (CSCF). What would be the impact of pursuing the current mechanism through to 2030? Does the EU Commissions' proposal of 15 July respond to the Council's requirements? Which alternative mechanisms could do so? This study examines four scenarios and their potential consequences. - Scenario 1 continues the current free allocation mechanism until 2030. The volume of free allocations thus calculated would be higher than the available free allocation cap and would need to be reduced by a Cross-Sectoral Correction Factor (CSCF) of 66% in 2030. Carbon costs would thus increase for all installations, regardless their exposure to carbon leakages, reducing the protection of most exposed sectors, while widely allocating sectors with limited exposure. - Scenario 2 analyses the proposal to implement an allocation mechanism based on recent industrial output combined with appropriate updating of benchmarks. This allocation method is more effective in combating carbon leakage, as it gives clearer incentive to maintain domestic production

Energy Efficiency and Emissions Trading. A PEEREA perspective after the entry into force of the Kyoto Protocol and of the EU ETS

International Nuclear Information System (INIS)

2006-01-01

The year 2005 was of particular importance for the climate change discussions. The Kyoto Protocol entered into force in February, following the Russian ratification. At the same time, the largest emission-trading scheme for CO2, the EU ETS came into operation. By the end of the year the first Meeting of the Parties to the UNFCCC took place in Montreal. The PEEREA Group discussed on several occasions the contribution of the Kyoto flexible mechanisms to boosting energy efficiency improvements. The role of energy efficiency projects in achieving climate change objectives was equally underlined. In 2004 a report was elaborated and subsequently printed on Carbon Trading and Energy Efficiency, with the understanding that the PEEREA Group will revisit the subject in order to reflect on new developments in this area. This paper, prepared by the Secretariat with the consultancy support of EcoSecurities, served the discussion and debate in the PEEREA Group on the latest developments and opportunities for energy efficiency in the climate change process. The paper provides only a brief introduction of the main concepts, as they were presented and discussed in the 2004 report. The focus is now on the operation of the EU ETS and on the implications for both EU and non EU PEEREA countries of the Linking Directive on the use of JI/CDM mechanisms in relation to improving energy efficiency

We examine liquidity effects after the onset of trading in phase II of the EU-ETS for European Union Allowance (EUA) futures contracts. We obtain evidence of long-term improvement in liquidity of the EEX EUA December 2008 futures contract after the commencement of trading in phase II. Our results suggest the application of a new regime of trading rules in Phase II led to the improvements in liquidity.

Environmental policies may have important consequences for firms’ competitiveness or profitability. However, the empirical literature shows that hardly any statistically significant effects on firms can be detected for the European Union Emissions Trading Scheme (EU ETS). On the basis of existing literature, we focus on potential explanations for why the empirical literature finds hardly any significant competitiveness effects on firms, least not during the first two phases of the scheme (...

The EU ETS and Dynamic Allocation in Phase IV—An Ex-Ante Assessment

Directory of Open Access Journals (Sweden)

Vicki Duscha

2018-02-01

Full Text Available Fear of lowering firms’ competitiveness and carbon leakage is the reason for large amounts of allowances in the European Union’s Emissions Trading System (EU ETS still being allocated for free. At the same time, unadjusted free allocation of allowances in times of economic recession is partly responsible for the large surplus of allowances that has cumulated in the EU ETS and that is lowering prices in the market. For Phase IV, the introduction of dynamic allocation has been proposed to react to significant changes in production, to prevent the accumulation of further surplus on the one hand and to protect installations from severe underallocation on the other. A reserve of about 400 million allowances is planned for that purpose. This paper analyses the demand for certificates from this reserve under different assumptions on production development as well as different design options for Phase IV. The analysis builds on freely available allocation data from Phase III along with projections of production trends from different time periods in the past. In most of the scenarios, the 400 million allowances are sufficient to fulfil demand for allowances from dynamic allocation until at least the second half of Phase IV (often even for the whole of Phase IV. Even though certain aspects analysed are now not fully compatible with the agreed-upon Phase IV revision, the analysis indicates that the amount of allowances foreseen for dynamic allocation is sufficient for Phase IV. In particular the threshold value of 10% that was introduced in the legislation will ensure that the demand of allowances is likely well below the demand found in the different scenarios in this analysis that neglects this threshold value.

Panorama 2016 - Overview of the refining industry in the European Union Emissions Trading System (EU ETS)

International Nuclear Information System (INIS)

Coussy, Paula; Jalard, Matthieu

2015-12-01

Since 2008, emissions from the refining sector have fallen by more than 12%, reaching 128 MtCO 2 e in 2014. Germany was the largest emitter of CO 2 e for the 2005- 2014 period. With Italy, Spain, the United Kingdom, France and the Netherlands, these six countries accounted for 71% of the industry's emissions in the EU ETS for 2014. During the 2008-2014 period, the European refining sector had a surplus of 74 MtCO 2 e, but since 2013 has had an annual deficit. Estimates show that the overall surplus of 74 MtCO 2 e should vanish by 2015. In the future, European demand for petroleum products will drop, and forecasts for crude processing are expected to decline. IFPEN estimates that, by 2035, this decline should reach 30%, leading to a 20% drop in the sector's emissions. Against this background, the amount of free allowances in the refining sector will fall, from 80% in 2014 to nearly 75% in 2020, leading to compliance costs for the European refining sector of approximately euro 600 million for 2020 alone, compared with the $6 billion needed for investment in Europe by 2035. Due to the great disparity in efficiency among European refineries (difference when compared with the benchmark), it is clear that it will be extremely costly for certain refineries to remain in operation. This will lead to the likely closure of refineries that are less efficient in terms of GHG emissions. (authors)

Tendances Carbone no. 83 'Reduction in free allowances for phase 3 of the EU ETS'

Alberola, Emilie; Sartor, Oliver

2013-01-01

Among the publications of CDC Climat Research, 'Tendances Carbone' bulletin specifically studies the developments of the European market for CO 2 allowances. This issue addresses the following points: In early September, the European Commission decided on the amount of free allowances attributed to industrial installations for phase 3 of the EU ETS, thus completing a process begun in 2009. This decision followed the examination of Member State proposals and their National Implementation Measures (NIM) with regard to two principal criteria: their compatibility with harmonized allocation rules and their consistency with benchmark values. The allocation proposals of all States were all approved with the exception of the allocation of 20 installations which are to be revised. In line with the ETS Directive, a correction factor was then applied so that these allocations do not exceed the maximum amount of free allocation allowed

Electron-spin polarization in tunnel junctions with ferromagnetic EuS barriers

Hao, X.; Moodera, J.S.; Meservey, R.

1989-01-01

The authors report here spin-polarized tunneling experiments using non-ferromagnetic electrodes and ferromagnetic EuS barriers. Because of the conduction band in EuS splits into spin-up and spin-down subbands when the temperature is below 16.7 K, the Curie temperature of EuS, the tunnel barrier for electrons with different spin directions is different, therefore giving rise to tunnel current polarization. The spin-filter effect, as it may be called, was observed earlier, directly or indirectly, by several groups: Esaki et al. made a tunneling study on junctions having EuS and EuSe barriers; Thompson et al. studied Schottky barrier tunneling between In and doped EuS; Muller et al. and Kisker et al. performed electron field emission experiments on EuS-coated tungsten tips. The field emission experiments gave a maximum polarization of (89 + 7)% for the emitted electrons. Although the previous tunneling studies did not directly show electron polarization, their results were explained by the same spin- filter effect. This work uses the spin-polarized tunneling technique to show directly that tunnel current is indeed polarized and polarization can be as high as 85%

Impacts on Competitiveness from EU ETS. An analysis of the Dutch Industry

The EU emissions trading scheme (ETS) was launched in 2005 to cap CO2 emissions from large industrial facilities and electricity producers. The European Commission is currently designing the post 2012 EU ETS, as outlined in COM(2008)16. Novel to this system is that a greater part of the rights will be auctioned. Auctioning in general assures a greater deal of efficiency compared to (certain types of) free allocation, lowers the administrative costs and prevents eventual windfall profits. However, auctioning also implies a potential loss of competitiveness for industry. If no international agreement on future climate policies is reached, firms may not be able to pass on the higher costs to their customers and may be faced with a loss in profitability and the threat of import substitution. In any emission trading scheme with an absolute cap, a relocation of production that is not covered by CO2 targets implies an increase in global CO2 emissions. This phenomenon has been labelled as 'carbon leakage'. To prevent carbon leakage, the Commission has proposed to exempt exposed sectors from auctioning and allocating them rights freely on the basis of a benchmark. A severe loss of competitiveness is here the main criterion against which it is decided whether sectors will be subject to auctioning or free allocation. This study has investigated which industrial sectors of the Dutch economy possibly face a loss of competitiveness from auctioning. The competitive position is determined by the combination of significant potential cost price increases and substantial imports and export flows to countries that have no comparable climate change policy. It appears that especially in the aluminium, fertilizer, iron and steel , inorganic and other base chemicals sectors relatively high cost price increases can be expected which may not be fully passed on to their customers. Profitability in these sectors may be reduced and the risk of carbon leakage increased. However, in terms of

Emissions trading listed as a flexible mechanism under the Kyoto Protocol is regarded as a market economy way in climate protection. Since 2005 the European Emissions Trading System (EU ETS) is the central climate policy instrument for reducing the emissions of greenhouse gases, in particular for carbon dioxide (CO{sub 2}). For years, however, the CO{sub 2} price is too low to direct the politically and socially targeted technical innovations in the electricity sector and the industry. The article analyses the temporary and structural causes of this problem, highlights the EU's reform efforts and points to areas of activity, the basis of which the EU ETS may act in the future as a central instrument for climate protection in the European Union. [German] Der im Kyoto-Protokoll als flexibler Mechanismus aufgefuehrte Emissionshandel gilt als marktwirtschaftlicher Weg in den Klimaschutz. Das Europaeische Emissionshandelssystem (EU ETS) ist seit 2005 das zentrale klimapolitische Instrument zur Senkung des Ausstosses von Treibhausgasen, insbesondere fuer Kohlenstoffdioxid (CO{sub 2}). Seit Jahren ist der CO{sub 2}-Preis jedoch zu gering, um die politisch und gesellschaftlich angestrebten technischen Innovationen im Stromsektor und der Industrie zu lenken. Der Artikel untersucht die temporaeren und strukturellen Ursachen dieses Problems, beleuchtet die Reformbestrebungen der EU und zeigt Handlungsfelder auf, anhand derer das EU ETS auch in Zukunft als zentrales Instrument fuer Klimaschutz in der Europaeischen Union fungieren kann.

Should the EU climate policy framework be reformed?

Directory of Open Access Journals (Sweden)

David ELLISON

2011-12-01

Full Text Available Though to-date the European Union (EU has played the most significant leadership role in international negotiations to reduce greenhouse gas (GHG emissions, the emission-reducing performance of individual EU Member states has for many been less than stellar. Several EU15 Member states continue to raise rather than lower emissions. Analysing the most successful policy instruments, this paper argues EU policy efforts could benefit from three important innovations. The following strategies – the adoption of an EU-wide FIT (feed-in tariff, an EU-wide carbon tax and more flexibility in the trading of carbon credits – could significantly improve emission reductions, their relative cost-efficiency and spread burden-sharing more evenly across technologies and Member states. This raises important questions, both about the effectiveness of EU and Kyoto-style commitments, as well as the EU Emission Trading Scheme (ETS. The commitment strategy, and in particular the EU ETS mechanism, have had the smallest impact on emission reductions. The proposed set of strategies could make a far greater contribution to future EU efforts and potentially lock in the impressive progress already made. Such a policy shift, if successful, would also greatly enhance the EU’s already significant credibility and bargaining power in international climate negotiations.

Firm performance and employment in the EU emissions trading scheme: An empirical assessment for Germany

International Nuclear Information System (INIS)

Anger, Niels; Oberndorfer, Ulrich

2008-01-01

This paper empirically investigates the role of the EU Emissions Trading Scheme (EU ETS) for firm performance and employment in Germany. We provide an overview of relative allowance allocation within the EU ETS as well as an econometric analysis for a large sample of German firms covered by the scheme in order to assess the impacts of EU emissions regulation on both firm revenues and employment. The dataset indicates that the EU ETS was in an overall long position in 2005, although allowance allocation was very heterogeneous across member states. Our econometric analysis suggests that, within the first phase of the EU ETS, relative allowance allocation did not have a significant impact on firm performance and employment of regulated German firms

Red light generation through the lead boro-telluro-phosphate glasses activated by Eu3+ ions

Lead boro-telluro-phosphate glasses containing 0.05 to 2.0 wt% of Eu3+ ions were prepared through melt quenching technique. Structural characteristics of title glasses were identified through XRD, FTIR and Raman studies. The optical properties of the prepared glasses were studied using UV-Vis-NIR absorption and photoluminescence spectra. From the resultant spectra, we have obtained the bonding parameters (δ), nephelauxetic ratio (β), direct and indirect band gaps and Urbach energy (ΔE) values. A deep red luminescence due to 5D0 → 7F2 transition of Eu3+ ions could be observed for the title glasses. The local site symmetry around the Eu3+ ions and the degree of Eu3+-O2- covalence were assessed from the luminescence intensity ratio of 5D0 → 7F2/5D0 → 7F1 transitions. Judd-Ofelt intensity parameters, calculated from the luminescence spectra, were used to estimate the radiative parameters like transition probability (A), branching ratio (βexp, βcal) and stimulated emission cross-section (σPE) concerning the 5D0 → 7FJ (J = 0, 1, 2, 3 and 4) transitions. The important laser parameters, gain bandwidth and optical gain are also estimated. The decay curves associated with the transition from 5D0 state was found to be single-exponential at all Eu3+ ion concentrations. CIE colour coordinates and colour purity of the prepared glasses were estimated from the CIE chromaticity diagram.

Societal benefits from EU reduction measures to decrease lead levels in the environment; Combining results from the EU funded projects INTARESE and HEIMTSA

Full Text Available The current paper combines the results of two Sixth Framework Program EU research projects aimed at developing and testing methods for integrated assessment of health risks from environmental stressors, i.e. the INTARESE and the HEIMTSA project, both of which covered a case study on environmental lead. The INTARESE case study on lead in Europe was meant to illustrate the use of the Integrated Monitoring Framework Strategy to assess the health outcome of environmental pollution by evaluating the associations between lead in various environmental compartments (air, soil, dust, drinking water and diet and lead concentrations in blood (B-Pb for various age-related sub-populations. The case study was aimed to investigate whether environmental, exposure and biomonitoring data at general population level, covering all EU member states, could be integrated.

The present study analyses the potential interactions between the EU Emissions Trading Scheme (EU ETS) and some selected energy and climate policy instruments in the Netherlands. These instruments include: (1) The Benchmarking Covenant (BC): a negotiated agreement with energy-intensive industries in order to improve their energy efficiency; (2) The Regulatory Energy Tax (REB): an ecotax (or levy) on the consumption of gas and electricity, including the partial exemption of this ecotax on renewable electricity; (3) The Environmental Quality of Electricity Production (MEP): a feed-in subsidy system for producers of renewable electricity; and (4) The system of Tradable Green Certificates (TGCs): a system of guarantees of origin to promote renewable electricity based on the partial exemption of the REB. A general finding of the present report is that once the EU ETS becomes operational, the effectiveness of all other policies to reduce CO2 emissions of the participating sectors becomes zero. The report explores the specific implications of this general finding for the coexistence of the EU ETS and the selected policy instruments in the Netherlands. It concludes that this coexistence will have a significant impact on the performance of both the EU ETS and the selected instruments in the Netherlands

Challenges of a common climate policy. An analysis of the development of the EU Emissions Trading Scheme

The emissions trading scheme (EU ETS) adopted by the European Union in 2003 was a new instrument for the EU and its Member States. It is one of the most important strategies of achieving the EU's greenhouse gas reduction target under the Kyoto Protocol. This book analyses the policy cycle of the EU ETS Directive, focusing on the crucial implementation phase. The revised EU ETS Directive of 2009 includes significant changes for greater ecological effectiveness, changes that were unlikely to have been adopted in 2003. It is evident that the experiences of the first phase influenced not only the second implementation phase but also the revision. The intensive learning process that took place on all levels was necessary to overcome institutional constraints so that the EU ETS could be successfully established and further developed. The EU ETS policy-making is a good example to demonstrate that output legitimacy challenges input legitimacy. With the centralisation of the EU ETS in 2013 it is likely to become a more effective system; however, the legislators from the Member States may lose influence. This problem will have to be addressed.

An emerging equilibrium in the EU emissions trading scheme

International Nuclear Information System (INIS)

Bredin, Don; Muckley, Cal

2011-01-01

The European Union's Emissions Trading Scheme (ETS) is the key policy instrument of the European Commission's Climate Change Program aimed at reducing greenhouse gas emissions to eight percent below 1990 levels by 2012. A critically important element of the EU ETS is the establishment of a market determined price for EU allowances. This article examines the extent to which several theoretically founded factors including, economic growth, energy prices and weather conditions determine the expected prices of the European Union CO 2 allowances during the 2005 through to the 2009 period. The novel aspect of our study is that we examine heavily traded futures instruments that have an expiry date in Phase 2 of the EU ETS. Our study adopts both static and recursive versions of the Johansen multivariate cointegration likelihood ratio test as well as a variation on this test with a view to controlling for time varying volatility effects. Our results are indicative of a new pricing regime emerging in Phase 2 and point to a maturing market driven by the fundamentals. These results are valuable both for traders of EU allowances and for those policy makers seeking to improve the design of the European Union ETS.

Strategic partitioning of emission allowances under the EU Emission Trading Scheme

The EU Emission Trading Scheme (ETS) is breaking new ground in the experience with emission trading regimes across multiple jurisdictions. Since the EU ETS covers only some industries, it implies a hybrid emission control scheme where EU member states must apply complementary domestic emissions regulation for the non-trading sectors of their economies in order to comply with their national emission reduction targets. The EU ETS thus opens up for strategic partitioning of national emissions budgets by the member states between trading and non-trading sectors. In this paper we examine the potential effects of such strategic behavior on compliance cost and emissions prices. We show that concerns on efficiency losses from strategic partitioning are misplaced. In turn, our analysis implicitly indicates significant political economy forces behind EU climate policy, as both cost-effective and strategically motivated partitioning of national emission budgets are far off from the actual break-down between trading and non-trading sectors.

The first period of the EU Emissions Trading Scheme (EU ETS) commenced on January 1st 2005. It implies new challenges to companies included in the scheme. A central challenge is the uncertainty related to the markets. In order to manage their risks and profitability companies need to be able to estimate future price developments of emission allowances. The University of Helsinki is conducting a research project in cooperation with the Helsinki University of Technology that will provide necessary information for analyzing European Union emission allowance (EUA) markets and create risk management competence. The objectives of the research project are (1) to develop a price estimation model for EU emission allowances and (2) to develop risk management competence related to EU ETS. With the price estimation model the short-term price developments of EUAs can be estimated. By utilizing the model companies can reduce uncertainties related to the markets. The project also delivers a general risk management model for EU ETS that aims at improving competitiveness of companies. (orig.)

Among the publications of CDC Climat Research, 'Tendances Carbone' bulletin specifically studies the developments of the European market for CO 2 allowances. This issue addresses the following points: On August 28 2012, the European Commission and the Australian Department for Climate Change announced that they will link their carbon markets. This link will take place in two stages: Australia will retain a fixed emission price of AU$ 23/tCO 2 ( euros 17.00) until 2015. Then, from July 1 2015 onwards, when the Australian Emission Trading Scheme (AETS) is introduced, EUAs will be eligible for Australian firms' domestic compliance, up to a usage limit of 50%. From 2018, the EU ETS facilities will become able to surrender Australian emissions allowances (AEUs) for their compliance purposes

The efficiency costs of separating carbon markets under the EU emissions trading scheme: A quantitative assessment for Germany

From 1 January 2005 onwards the European Union has launched the first large-scale international carbon emissions trading program. As the EU Emissions Trading Scheme (EU-ETS) covers only part of domestic carbon emissions, it implies a segmented environmental regulation scheme: Each EU Member State must specify additional domestic abatement policies for the sectors outside the EU-ETS in order to meet its emissions budget under the EU Burden Sharing Agreement. We highlight the generic problems of segmented carbon regulation in terms of information requirements for international carbon prices and domestic abatement costs of sectors outside the EU-ETS. Based on numerical simulations for Germany, we quantify the excess costs of segmented carbon regulation and conclude that inefficiencies can be much better explained by lobbying of influential EU-ETS sectors than by information problems.

In its fight against climate change the EU is committed to reducing its overall greenhouse gas emissions to at least 20% below 1990 levels by 2020. To meet this commitment, the EU builds on segmented market regulation with an EU-wide cap-and-trade system for emissions from energy-intensive installations (ETS sectors) and additional measures by each EU Member State covering emission sources outside the cap-and-trade system (the non-ETS sector). Furthermore, the EU has launched additional policy measures such as renewable energy subsidies in order to promote compliance with the climate policy target. Basic economic reasoning suggests that emission market segmentation and overlapping regulation can create substantial excess costs if we focus only on the climate policy target. In this paper, we evaluate the economic impacts of EU climate policy based on numerical simulations with a computable general equilibrium model of international trade and energy use. Our results highlight the importance of initial market distortions and imperfections as well as alternative baseline projections for the appropriate assessment of EU compliance cost. (author)

Free allocations in EU ETS Phase 3: The impact of emissions performance benchmarking for carbon-intensive industry - Working Paper No. 2013-14

Lecourt, S.; Palliere, C.; Sartor, O.

2013-02-01

From Phase 3 (2013-20) of the European Union Emissions Trading Scheme, carbon-intensive industrial emitters will receive free allocations based on harmonised, EU-wide benchmarks. This paper analyses the impacts of these new rules on allocations to key energy-intensive sectors across Europe. It explores an original dataset that combines recent data from the National Implementing Measures of 20 EU Member States with the Community Independent Transaction Log and other EU documents. The analysis reveals that free allocations to benchmarked sectors will be reduced significantly compared to Phase 2 (2008-12). This reduction should both increase public revenues from carbon auctions and has the potential to enhance the economic efficiency of the carbon market. The analysis also shows that changes in allocation vary mostly across installations within countries, raising the possibility that the carbon-cost competitiveness impacts may be more intense within rather than across countries. Lastly, the analysis finds evidence that the new benchmarking rules will, as intended, reward installations with better emissions performance and will improve harmonisation of free allocations in the EU ETS by reducing differences in allocation levels across countries with similar carbon intensities of production.

The EU as a frontrunner on greenhouse gas emissions trading. How did it happen and will the EU succeed?

International Nuclear Information System (INIS)

Christiansen, Atle C.; Wettestad, Joergen

2003-01-01

The objective of this paper is first to provide empirical evidence of what can be seen as a rather remarkable change in EU's position on the use of greenhouse gas (GHG) emissions trading (ET) in climate policy, from the role of a sceptic in the run-up to Kyoto towards more of a frontrunner. The paper argues that there is a synergistic and multilevel mix of explanatory factors for this 'U-turn', including developments at the international, EU, Member State, sub-national, and even down to the personal level. Second, the paper explores and discusses the philosophy behind the Commission's proposal for a directive on GHG ET. Third, the paper examines the prospects for 'success' of a scheme for EU-wide ET using a multifaceted set of metrics. In brief, we argue that output success - the chances for having a directive adopted - hinges on the resolution of two key issues. First, whether the preliminary phase is to be mandatory or voluntary, and second, incompatibilities with domestic ET schemes. Outcome success - steering and cost-effectiveness - will in turn depend on factors like the coverage of the scheme and inclusion of project-based credits, while more long-term political implications hinges on the successful adoption and operation of the scheme

Report on modelling the macroeconomic competitiveness impacts of EU climate change policy

International Nuclear Information System (INIS)

2007-01-01

This report details the results of a study carried out by Oxford Economics on the macroeconomic impacts of the EU Emissions Trading Scheme (EU ETS) on competitiveness in different sectors and different Member States. An economic model was used to assess the impacts of carbon pricing, building on previous work that looked at the effects on the UK economy. The model was used to estimate the impact on competitiveness and output associated with various carbon prices and assumptions for the proposed third EU ETS trading period (2013-2023) by sector for all countries. The model covered 30 sectors for each of the 27 EU Member states plus the USA, Japan and China. The report describes the EU model methodology (direct cost effects, second-round cost effects, cost effects without substitution, cost effects after substitution, pass through to prices, and output effects) and the key results in terms of: impacts of carbon-reduction policies unilateral EU action, sectoral impacts, electricity generation sector only; the non-power sector in the ETS; global action; developed world action; and a summary across all scenarios. The three annexes set out the UK Energy Industry Model (UKEIM), model equations for the EU-wide model and modelling assumptions for electricity generation

Modelling Eu(III) speciation in a Eu(III)/PAHA/α-Al2O3 ternary system

Janot, Noemie; Reiller, Pascal E.; Benedetti, Marc F.

2013-01-01

In this work, modelling of Eu(III) speciation in a ternary system, i.e., in presence of purified Aldrich humic acid (PAHA) and α-Al 2 O 3 , is presented. First, the mineral surface charge is measured by potentiometric titrations and then described using the CD-MUSIC model. This model is also used to describe Eu(III) binding to the α-Al 2 O 3 surface at different pH values, ionic strength and mineral concentrations. Time resolved luminescence spectroscopy (TRLS) is then used to study the binding of Eu(III) to PAHA at pH 4 with different humic acid concentrations. The spectra are used to calculate a spectroscopic 'titration curve', used to determine Eu(III)/PAHA binding parameters in the NICA-Donnan model. Following a previous study (Janot et al., Water Res. 46, 731-740), modelling of the ternary system is based upon the definition of two PAHA pools where one fraction remains in solution and the other is adsorbed onto the mineral surface, with each possessing different proton and metal binding parameters. The modification of protonation behaviour for both fractions is examined using spectrophotometric titrations of the non adsorbed PAHA fraction at different organic/mineral ratios. These data are then used to describe Eu(III) interactions in the ternary system: Eu(III) re-partitioning in the ternary system is calculated for different pH, ionic strength and PAHA concentrations, and results are compared to experimental observations. The model is in good agreement with experimental data, except at high PAHA fractionation rates. Results show that organic complexation dominates over a large pH range, with the predominant species existing as the surface-bound fraction. Above pH 8, Eu(III) seems to be mostly complexed to the mineral surface, which is in agreement with previous spectroscopic observations (Janot et al., Environ. Sci. Technol. 45, 3224-3230).

Does EU emissions trading bite? An event study

Jong, Thijs; Couwenberg, Oscar; Woerdman, Edwin

2014-01-01

The aim of this paper is to examine whether shareholders consider the EU Emissions Trading Scheme (EU ETS) as value-relevant for the participating firms. An analysis is conducted of the share prices changes as caused by the first publication of compliance data in April, 2006, which disclosed an over-allocation of emission allowances. Through an event study, it is shown that share prices actually increased as a result of the allowance price drop when firms have a lower carbon-intensity of production and larger allowance holdings. There was no significant value impact from firms' allowance trade activity or from the pass-through of carbon-related production costs (carbon leakage). The conclusion is that the EU ETS does ‘bite’. The main impact on the share prices of firms arises from their carbon-intensity of production. The EU ETS is thus valued as a restriction on pollution. - Highlights: • Firms are more positively valued with lower carbon-intensities of production. • Firms are more negatively valued with smaller holdings of allowances. • The stock market does not value the firms' allowance trade activity. • The stock market does not seem to value the pass-through of carbon costs in product prices

Phase 2 compliance: an excess amount of 1,425 Mt including the use of 1,059 million international credits. - Back-loading: the European Parliament's ENVI Commission will vote again on 19 June. - Competitiveness: the European Commission is launching a consultation process regarding a review of the list of sectors exposed to carbon leakage for the period between 2015 and 2019

Carbon Leakage in the Primary Aluminium Sector: What evidence after 6 1/2 years of the EU ETS? - Working Paper No. 2012-12

International Nuclear Information System (INIS)

Sartor, Oliver

2012-02-01

This paper provides an econometric analysis of the evidence of carbon leakage from the European primary aluminium industry during the first 6 1/2 years of the EU ETS. The findings suggest that while rising electricity prices have played a critical role in reducing the competitiveness of EU primary aluminium smelting in recent years, no evidence of carbon leakage can be detected so far. Other factors, including rising primary energy prices and changes in EU competition law regarding long term contracts, appear to be more important factors explaining the rise in net imports of primary aluminium and the gradual closure of a number of European primary smelters during the past 6 1/2 years. Our results suggest that the carbon leakage debate in this sector may therefore be better seen in terms of not accelerating the decline of the industry in Europe, rather than preventing it, and that any state-aid to the industry to prevent carbon leakage should therefore be applied accordingly.

This issue addresses the following points: The publication of the 2011 compliance data confirms that the EU ETS carbon price will remain at a low level in the short and medium term. These data indicate a drop in CO 2 emissions by 2.1% and the return of 254.7 million Kyoto credits up 86% compared to 2010. In the context of a growing surplus of allowances since 2008, these two trends further weaken the demand for allowances

It has been repeatedly said that the economic slowdown that began in 2008 largely explains the fall in carbon emissions recorded in Europe since the introduction of the European Union Emissions Trading Scheme (EU ETS). In fact, the European Union stated this very clearly in its initial report on the operation of the EU ETS in November 2012. Using an econometric analysis based on a business-as-usual scenario, it is shown that reductions of around 1.1 GtCO 2 are likely to have been achieved within the scope of the 11.000 installations covered by the EU ETS. Of those reductions, between 600 and 700 million tonnes are said to have resulted from the two policies in the 2020 Climate and Energy Package, which aims to achieve a 20% renewable energy target (a decrease of around 500 million tonnes) and a 20% improvement in energy intensity (a decrease of between 100 and 200 million tonnes). The economic downturn also played a significant, although not dominant role in the decrease in CO 2 emissions, the impact of which was estimated at 300 million tonnes. Price substitution effects induced by coal and gas prices also seem to have affected emissions, within an order of magnitude of around 200 million tonnes. The study does not enable any impact created by the carbon price to be identified. It is important. However, to emphasize that the economic downturn and the development of RE were responsible for the decrease of the carbon price, and specifically marginalised its influence in terms of CO 2 emission reductions at the installations covered within the EU.

Rethinking EU Citizenship: Towards the Postmodern Ethics of Citizenship

Directory of Open Access Journals (Sweden)

Sanja IVIC

2009-11-01

Full Text Available The concept of EU citizenship reflects EU politics of (fixed identity, which guarantees rights only to the homogenous groups (and individuals as representatives of these groups. Hence, it leaves room for marginalizing, othering, excluding and other forms of discrimination, by creating binary oppositions: we/they, citizen/alien, EU/non-EU and so forth. EU citizenship is based on the modernist ethics of priority of right over the good. It is created to promote European idea, so it has only instrumental value. On the other hand, the politics of affinity leads to the substantive EU citizenship founded on multiple identities. The politics of affinity requires a new ethics which will lead to transformation of the main concepts of EU legal discourse.

Both Germany and the European Union have set themselves targets for the reduction of greenhouse gas (GHG) emissions. The EU was the forerunner in 2008 when it adopted the Climate and Energy package and set a target of reducing GHG emissions by 20 % by 2020 compared to 1990. Two years later, Germany adopted a range of national GHG targets in the context of the German government's Energy Concept. This includes a 40% emissions reduction target to be met by 2020. One of the main instruments for achieving GHG emissions reduction targets is the EU Emissions Trading Scheme (EU ETS), which covers all large industrial and combustion installations in Europe. According to the agreement made in 2008 (Climate and Energy Package), the effort to achieve the EU's 20 % reduction target by 2020 was split between the ETS sector (2/3 of the reduction effort, representing a 21 % reduction in GHG emissions for installations covered under the ETS compared to 2005) and the non-ETS sector (1/3 of the reduction effort, representing a 10 % reduction compared to 2005). Logically, GHG emissions reductions occurring in German ETS installations count both towards the EU and the national target. This research project has been commissioned to analyse whether the ETS in its cur-rent design can contribute its fair share in efforts to meet the national emissions reduc-tion target. This question is particularly relevant in light of the following considerations: - The new German Coalition Agreement, signed in December 2013, reiterated the national target of a 40 % reduction of GHG emissions by 2020 compared to 1990 levels. - At the same time, the new Coalition Agreement stated that changes to the ETS are only to be considered if the EU GHG emissions reduction target will not be met. - There is a surplus of CO2 allowances on the ETS market, which undermines the credibility of the instrument as well as the integrity of the emissions reduction tar-gets (both European and national). At the same

The results of x-ray excited optical luminescence (XEOL), photoluminescence (PL), photostimulated luminescence (PSL) and x-ray photoemission spectroscopy (XPS) studies on the x-ray storage phosphor BaFBr:Eu are presented in this paper. Analyses of XEOL, PL and PSL spectra reveal features corresponding to the transitions from 4f sup 6 td sup 1 to 4f sup 7 configurations in different site symmetries of Eu sup 2 sup +. Increasing x-ray dose is seen to lead to a red shift in the maximum of the PL excitation spectrum for the 391 nm emission. The XEOL and XPS spectra do not show any signature of Eu sup 3 sup + in the samples studied by us, directly raising doubts about the model of Takahashi et al in which Eu sup 2 sup + is expected to ionize to Eu sup 3 sup + upon x-ray irradiation and remain stable until photostimulation. XEOL and PSL experiments with simultaneous x-ray irradiation and He - Ne laser excitation as well as those with sequential x-ray irradiation and laser stimulation bring out the competition betwe...

We assess the political-economy determinants of allowance allocation in the EU Emissions Trading Scheme (EU ETS). A common-agency model suggests that the government considers the preferences of sectoral interest groups when allocating emissions permits, so that industries with a more powerful lobby face a lower regulatory burden. An empirical analysis of the first trading phase of the EU ETS corroborates our theoretical prediction, but also reveals that the political-economy determinants of permit allocation are more complex. Employing instrumental-variable estimation technique, we find that large carbon emitters that were represented by powerful interest groups received higher levels of emissions allowances

The next step in Europe's climate action. Setting targets for 2030. Reviving the EU emissions trading system and bringing EU greenhouse gas emissions on a 2C track. Policy brief

This paper explains how setting 2030 targets will reinvigorate the ETS and will put EU emissions on track to limit global temperature increase below two degrees Celsius (2C). This paper describes four key findings for EU policymakers engaged in preparing EU energy and climate measures for 2030 and for the longer term. The European Commission estimates that by 2020, the companies participating in the ETS will have accumulated a surplus of 1.5 to 2.3 billion allowances, which may be banked and used beyond 2020. This is about the same size as the annual emissions budget of ETS companies (just below 2 billion tonnes). Applying equity principles to the global distribution of efforts in reaching the 2C goal, an indicative 'fair' EU contribution would be a reduction of EU greenhouse gas emissions by around 49% (median of a full range from 39 to 79%) by 2030 compared to 1990 levels. The 2030 targets can be set in a way to also accommodate the surplus expected until 2020. If the entire surplus of allowances from the ETS were to be used after 2020, the 2030 target has to become around 7 percentage points more stringent to compensate for that. Alternatively, the trajectory of the target from 2021 to 2030 could be set to compensate for the surplus. In addition, a more ambitious trajectory towards 2030 would cast its shadow on the mitigation in the period 2013-2020. It would strengthen the ETS, in conjunction with any other ETS recalibration options such as shifting the auctioning ('backloading') or cancelling allowances before 2020.

Hvorfor Habermas' vision for et demokratisk EU ikke kan stå alene

DEFF Research Database (Denmark)

Sørensen, Ditte Maria Brasso

2016-01-01

This article discusses Habermas’ vision of a supranational yet democratic EU. The article engages in a discussion of what I take to be two problematic elements of Habermas’ model of EU democracy. Firstly, it discusses the European Parliament as a representative channel, which should, according...... to Habermas, be strengthened. I here raise the concern that Habermas is not sufficiently sensitive to the tension between the recognition of a weak public and the desire for a strong Parliament. Secondly, I discuss whether executive federalism can also be circumvented by strengthening not just...... the representation of the European citizens, but also by strengthening parliamentarian representation of the European peoples. Based on these two critiques I end up arguing that Habermas’ vision for EU democracy would benefit from drawing inspiration from the demoicracy literature’s focus on alternative channels...

The main objective of the present study is to analyse the implications of shifting from free allocation to auctioning of EU ETS allowances (EUAs) for the power sector in the Netherlands. In order to achieve this objective, this study has used three methodological approaches, including theoretical, empirical and model analyses of the impact of free allocations versus auctioning of EUAs on the power sector, notably in the Netherlands. In addition, as Combined Heat and Power (CHP) plays a major role in the electricity sector of the Netherlands, the present study also pays some particular attention to the implications of shifting from free allocation to EUA auctioning for the CHP sector in the Netherlands

Varying Eu2+ magnetic order by chemical pressure in EuFe2(As1-xPx)2

Based on low-field magnetization measurements on a series of single crystals, we present a scheme of the Eu2+ spin alignment in EuFe2(As1-xPx)2. We explain observations of the Eu2+ ordering previously reported, reconciling different existing phase diagrams. The magnetic moments of the Eu2+ ions are slightly canted, yielding a ferromagnetic contribution along the c direction that becomes stronger with pressure, until superconductivity sets in. The spin-density wave as well as the superconducting phase coexist with an antiferromagnetic interlayer coupling of the canted spins. Reducing the interlayer distance finally leads to a ferromagnetic Eu2+ interlayer coupling and to the suppression of superconductivity.

Full Text Available The focus in the article is on creativity in the higher education sector in terms of gender perspective. The question posed concerns the relation between women’s and men’s patent activities and R&D expenditures. The paper is based on the data from the European Patent Office, 1999-2013 concerning creative activities performed by women and men in the higher education sector. The paper looks into the dynamics of changes in terms of the number of women and men researchers, R&D personnel and inventors, and combines them with the changes in R&D expenditures in the higher education sector. The analysis is conducted for the two groups of leading EU countries in the light of their patent activities. The objective of this exercise is to present the correlation between R&D expenditures and women and men in the R&D sectors, comparing these two groups of the EU countries.

This paper explores the incentives for energy efficiency induced by the European Union Emissions Trading Scheme (EU ETS) for installations in the energy and industry sectors. Our analysis of the National Allocation Plans for 27 EU Member States for phase 2 of the EU ETS (2008-2012) suggests that the price and cost effects for improvements in carbon and energy efficiency in the energy and industry sectors will be stronger than in phase 1 (2005-2007), but only because the European Commission has substantially reduced the number of allowances to be allocated by the Member States. To the extent that companies from these sectors (notably power producers) pass through the extra costs for carbon, higher prices for allowances translate into stronger incentives for demand- side energy efficiency. With the cuts in allocation to energy and industry sectors these will be forced to greater reductions, thus the non-ET sectors like household, tertiary and transport will have to reduce less, which is more in line with the cost-efficient share of emission reductions. The findings also imply that domestic efficiency improvements in the energy and industry sectors may remain limited since companies can make substantial use of credits from the Kyoto mechanisms. The analysis of the rules for existing installations, new projects and closures suggests that incentives for energy efficiency are higher in phase 2 than in phase 1 because of the increased application of benchmarking to new and existing installations and because a lower share of allowances will be allocated for free. Nevertheless, there is still ample scope to further improve the EU ETS so that the full potential for energy efficiency can be realized. (orig.)

The Impact of the EU Emissions Trading System on CO{sub 2} Intensity in Electricity Generation

Prior to the launch of the EU Emissions Trading System (EU ETS) in 2005, the electricity sector was widely proclaimed to have more low-cost emission abatement opportunities than other sectors. If this were true, effects of the EU ETS on carbon dioxide (CO{sub 2}) emissions would likely be visible in the electricity sector. Our study looks at the effect of the price of emission allowances (EUA) on CO{sub 2} emissions from Swedish electricity generation, using an econometric time series analysis for the period 2004-2008. We control for effects of other input prices and hydropower reservoir levels. Our results do not indicate any link between the price of EUA and the CO{sub 2} emissions of Swedish electricity production. A number of reasons may explain this result and we conclude that other determinants of fossil fuel use in Swedish electricity generation probably diminished the effects of the EU ETS

Janssen, Matthias; Peichert, Patrick; Perner, Jens; Riechmann, Christoph

Emissions trading listed as a flexible mechanism under the Kyoto Protocol is regarded as a market economy way in climate protection. Since 2005 the European Emissions Trading System (EU ETS) is the central climate policy instrument for reducing the emissions of greenhouse gases, in particular for carbon dioxide (CO 2 ). For years, however, the CO 2 price is too low to direct the politically and socially targeted technical innovations in the electricity sector and the industry. The article analyses the temporary and structural causes of this problem, highlights the EU's reform efforts and points to areas of activity, the basis of which the EU ETS may act in the future as a central instrument for climate protection in the European Union.

The central importance of the EU emission trading scheme for achievement of the German climate protection target of 40% until 2020

International Nuclear Information System (INIS)

Hermann, Hauke; Cludius, Johanna

Both Germany and the European Union have set themselves targets for the reduction of greenhouse gas (GHG) emissions. The EU was the forerunner in 2008 when it adopted the Climate and Energy package and set a target of reducing GHG emissions by 20 % by 2020 compared to 1990. Two years later, Germany adopted a range of national GHG targets in the context of the German government's Energy Concept. This includes a 40% emissions reduction target to be met by 2020. One of the main instruments for achieving GHG emissions reduction targets is the EU Emissions Trading Scheme (EU ETS), which covers all large industrial and combustion installations in Europe. According to the agreement made in 2008 (Climate and Energy Package), the effort to achieve the EU's 20 % reduction target by 2020 was split between the ETS sector (2/3 of the reduction effort, representing a 21 % reduction in GHG emissions for installations covered under the ETS compared to 2005) and the non-ETS sector (1/3 of the reduction effort, representing a 10 % reduction compared to 2005). Logically, GHG emissions reductions occurring in German ETS installations count both towards the EU and the national target. This research project has been commissioned to analyse whether the ETS in its cur-rent design can contribute its fair share in efforts to meet the national emissions reduc-tion target. This question is particularly relevant in light of the following considerations: - The new German Coalition Agreement, signed in December 2013, reiterated the national target of a 40 % reduction of GHG emissions by 2020 compared to 1990 levels. - At the same time, the new Coalition Agreement stated that changes to the ETS are only to be considered if the EU GHG emissions reduction target will not be met. - There is a surplus of CO2 allowances on the ETS market, which undermines the credibility of the instrument as well as the integrity of the emissions reduction tar-gets (both European and national). At the same time, the

Within its Energy and Climate Package, adopted by the European Parliament in December 2008, the European commission set a 10% minimum for the market share of renewables in the transport sector in 2020. To find the appropriate instruments to reach this target and the instrument mix with which biomass use in general could be best stimulated are the main questions of this project. An important instrument of the European Climate Policy is the European Emissions Trading Scheme (EU-ETS), which started operation in 2005. Previous work done within Bioenergy NoE showed that only a high share of auctioning of allowances and a high CO2 price provide necessary incentives for a higher biomass use. According to the Energy and Climate Package, all allowances will be auctioned in the energy sector from 2013 on, with exceptions for a few CEE countries. Based on work done within the project, a model has been developed to analyse at which CO2 price biomass becomes competitive in case of 100 per cent auctioning or at a lower level. The European Commission furthermore decided not to include the road transport sector into the EU-ETS until 2020. Whether the inclusion of the road transport sector in the EU-ETS, could help introducing biofuels, a separate trading scheme for biofuels should be set up, or biofuels should be addressed with other policy instruments, was another main question of this project. The first result shows that an integrated scheme would hardly have any effects on the use of liquid biofuels in the transportation sector, but might cause higher CO2 prices for the energy and industry sector. A separate trading scheme has been implemented in the UK in 2008, California is planning such as scheme in addition to include the road transport sector into the future ETS. Within this project the design of such as system has been elaborated based on the comparison of several policy instruments to increase the use of liquid biofuels in the transportation sector.

As part of the storage of nuclear wastes in a deep underground disposal, radionuclides sorption on geological or engineered barriers is one of the most important factor which could enhance retardation. Thus, the knowledge of such mechanisms is needed. For this purpose, we chose to experimentally define sorption equilibria before performing simulation of retention data. Several phosphate compounds are potential candidates as engineered barrier additives. We considered Th{sub 4}(PO{sub 4}){sub 4}P{sub 2}O{sub 7}, Zr{sub 2}O(PO{sub 4}){sub 2} which allow to study the effect of PO{sub 4} and P{sub 2}O{sub 7} groups separately. Eu(III) and U(IV) ions were used as structural probes in order to simulate actinides (III) and (VI) behavior. X-ray powder diffraction, IR spectroscopy and electron probe microanalysis were used to characterized the synthesized solids. Electrophoretic measurements showed an amphoteric behavior of surface sites. Moreover, laser spectro-fluorimetry experiments indicated that no diffusion phenomena of the sorbed ion inside the solid occurs. Thus, we considered that a surface complexation model should be applied. Laser spectro-fluorimetry and XPS allowed to determine the nature of surface sites. ZrP{sub 2}O{sub 7} presents only one single site (P{sub 2}O{sub 7} groups) whereas Th{sub 4}(PO{sub 4}){sub 4}P{sub 2}O{sub 7} and Zr{sub 2}O(PO{sub 4}){sub 2} admit two types of sites (PO{sub 4}/P{sub 2}O{sub 7} and PO{sub 4}/oxo groups, respectively). Sorbed species were identified using laser spectro-fluorimetry which indicate that, in KNO{sub 3} 0.5 M medium and for a known surface site, there are two surface complexes for U(VI) (sorption of UO{sup 2+}{sub 2} et de UO{sub 2}NO{sup +}{sub 3} species) and only one for Eu(III) (sorption of EuNO{sup 2+}{sub 3}). They are linked to the substrate as bidentate inner sphere complexes (EXAFS study). Surface acidity constants were determined by simulation of potentiometric titration curves obtained for each solid

Full text: Global use of nuclear power is likely to continue to grow in the coming decades. Some countries have chosen to invite multiple vendors for NPP technology supply. The worldwide expansion of nuclear power use and the multi-vendor paradigm inevitably lead to the need of harmonized approaches towards safety and the initial step here is harmonization of education and training (E&T) efforts between recipient and vendor countries and between vendors as well. Establishing international and regional E&T networks is the vital mechanism of the harmonization. The present paper gives an example of collaboration between Russia and the EU through achievements of ENEN-RU projects aimed at harmonization of E&T efforts in nuclear field. One of the goals of this activity is to introduce double-degree programmes in nuclear engineering in Russian and EU universities. To support this initiative ROSATOM-CICE&T is currently developing multimedia-based fundamental educational courses in Russian and English languages. The courses will be also used as the backbone for new nuclear engineering programmes in the universities of newcomer states. To provide a harmonized development of operating personnel career trajectories in these countries an applied bachelor programme for operating personnel has been developed. (author

A single link from the SD band in {sup 143}Eu was found at 3364 keV. The level where it feeds into has not been identified. Alpha-particle energy (E{sub {alpha}}) spectra leading to the SD band and to normal states in {sup 143}Eu were measured and a correlation was found between E{sub {alpha}} and the level spin of the residual nucleus.

Constructing post-carbon institutions: Assessing EU carbon reduction efforts through an institutional risk governance approach

International Nuclear Information System (INIS)

LaBelle, Michael

2012-01-01

This paper examines three different governance approaches the European Union (EU) and Member States (MS) are relying on to reach a low carbon economy by 2050. Current governance literature explains the operational methods of the EU's new governance approach to reduce carbon emissions. However, the literature neglects to account for the perceived risks that inhibit the roll-out of new low carbon technology. This article, through a novel approach, uses a grounded theoretical framework to reframe traditional risk literature and provides a connection to governance literature in order to assess the ability of EU governance mechanisms to reduce carbon emissions. The empirical research is based on responses from European energy stakeholders who participated in a Delphi method discussion and in semi-structured interviews; these identified three essential requirements for carbon emissions to be reduced to near zero by 2050: (1) an integrated European energy network, (2) carbon pricing and (3) demand reduction. These features correspond to institutionalized responses by the EU and MS: the Agency for the Cooperation of Energy Regulators (ACER); European Union Emission Trading Scheme (EU ETS) and energy efficiency directives and policies integrated into existing MS institutions. The theoretical and empirical findings suggest that governance by facilitation (energy efficiency) fails to induce significant investment and new policy approaches and cannot be relied on to achieve requisite reductions in demand. Governance by negotiation (ACER) and governance by hierarchy (EU ETS) do reduce risks and may encourage the necessary technological uptake. The term ‘risk governance’ is used to explain the important role governance plays in reducing risks and advancing new technology and thereby lowering carbon emissions in the energy sector. - Highlights: ► This article assesses the role of EU institutions in reducing carbon emissions by 2050. ► Empirical research is based on Delphi

Formation of nanostructures in Eu3+ doped glass-ceramics: an XAS study.

We describe the results of x-ray absorption experiments carried out to deduce structural and chemical information in Eu(3+) doped, transparent, oxyfluoride glass and nanostructured glass-ceramic samples. The spectra were measured at the Pb and Eu-L(III) edges. The Eu environment in the glass samples is observed to be similar to that of EuF(3). Complementary x-ray diffraction experiments show that thermal annealing creates β-PbF(2) type nanocrystals. X-ray absorption indicates that Eu ions act as seeds in the nanocrystal formation. There is evidence of interstitial fluorine atoms around Eu ions as well as Eu dimers. X-ray absorption at the Pb-L(III) edge shows that after the thermal treatment most lead atoms form a PbO amorphous phase and that only 10% of the lead atoms remain available to form β-PbF(2) type nanocrystals. Both x-ray diffraction and absorption point to a high Eu content in the nanocrystals. Our study suggests new approaches to the oxyfluoride glass-ceramic synthesis in order to further improve their properties.

The EU system for emissions trading after year 2012; EU:s system foer handel med utslaeppsraetter efter 2012

The Government has instructed the Swedish Energy Agency and the Swedish Environmental Protection Agency to put forward a proposal for how the EU Emissions Trading Scheme (EU ETS) should be developed after 2012, subject to the overall objective of continuing to reduce emissions with the aim of achieving the long-term objectives of the Convention on Climate Change. In its Council Conclusions (7619/1/05) the EU has interpreted the long-term objectives of the Convention on Climate Change as aiming to achieve emission reductions of 15-30 % in the industrialised countries by 2020. According to Council Conclusions (13435/05), the EU has also decided that the Emissions Trading Scheme should continue after 2012. The starting point for this report is that, after 2012, the Scheme will be a key instrument in achieving cost-efficient emission reductions, not only within the EU but also globally, and regardless of whether, with effect from 2013, the Scheme has become a part of an international climate regime, or is serving as a transition to some future new international climate regime. The purpose of this report is to provide a proposal for how the Emissions Trading Scheme should be developed after 2012. The aim is to construct a system that helps to reduce global emissions of greenhouse gases (maintaining climate integrity), that assists measures being taken where they are cheapest (cost efficiency), that is accepted by parties concerned and by the general public (confidence inspiring), and which does not adversely affect the competitiveness of business or industry (competition-neutral). The Agencies recommend that Sweden should adopt the following standpoints concerning development of the EU Emissions Trading Scheme after 2012. (Recommended changes to the system presuppose a harmonised implementation throughout the EU.): In connection with international negotiations, Sweden should press for the Emissions Trading Scheme to be developed in such a way as to make it possible to

In this study, we report the comparison between Eu 3+ -doped silica nanoparticles synthesized by Stoeber method using Eu(NO 3 ) 3 or Eu(acac) 3 as precursors. The impact of different europium species on the properties of the final silica nanospheres is investigated in details in terms of size, morphology, reachable doping amount, and luminescence efficiency. Moreover, the results obtained for different thermal treatments are presented and discussed. It is shown that the organic complex modify the silica growing process, leading to bigger and irregular nanoparticles (500-800 nm) with respect to the perfectly spherical ones (400 nm) obtained by the nitrate salt, but their luminescence intensity and lifetime is significantly higher when 800-900 o C annealing is performed.

The effect of EU derogation strategies on the compliance costs of the nitrate directive.

Within the framework of the nitrate directive, member states have the opportunity to apply for derogation, i.e. increasing fertilisation standards under certain conditions. Several EU regions have utilised this opportunity, but each in a different way, resulting in six very different derogation policies within the EU in 2009. This paper focuses on the differences between the policies applied and makes an assessment with regard to the impact of these differences on the application rate for derogation, the manure surplus and the cost of allocating manure. Based on the MP-MAS model described by Van der Straeten et al. (2010) the different scenarios are applied on a single case area (Flanders) and the economic effects have been simulated. Results show considerable differences between the policy alternatives, leading to the conclusion that member states not only have to focus on whether or not to allow derogation, but also on the actual details of the derogation policy. Granting derogation at parcel level (plot of land), instead of farm level, increases the potential effect of derogation; the level of increase in fertilisation standards under derogation determines the application rate for derogation: a higher increase leads to a higher application rate.

This paper provides a comprehensive analysis of how the European Emission Trading System (EU ETS) as the core climate policy instrument of the European Union has impacted innovation. Towards this end, we investigate the impact of the EU ETS on research, development, and demonstration (RD and D), adoption, and organizational change. In doing so, we pay particular attention to the rela-tive influences of context factors (policy mix, market factors, public acceptance) as well as firm characteristics (value chain position, technology portfolio, size, vision). Empirically, our analysis is based on multiple case studies with 19 power generators, technology providers, and project developers in the German power sector which we conducted from June 2008 until June 2009. We find that the innovation impact of the EU ETS has remained limited so far because of the scheme's initial lack in stringency and predictability and the relatively greater importance of context factors. Additionally, the impact varies tremendously across technologies, firms, and innovation dimensions, and is most pronounced for RD and D on carbon capture technologies and corporate procedural change. Our analysis suggests that the EU ETS by itself may not provide sufficient incentives for fundamental changes in corporate climate innovation activities at a level adequate for reaching political long-term targets. Based on the study's findings, we derive a set of policy and research recommendations. (orig.)

We have studied the valence behavior of rare-earth ions, in particular Eu-ions, in a cubic intermetallic compound Ce{sub 0.5}Eu{sub 0.5}Pd{sub 3}B{sub 0.5} which is a homogeneous solid solution of two mixed-valent compounds CePd{sub 3} and EuPd{sub 3}B. Results of {sup 151}Eu Moessbauer spectroscopic measurements show that two different valence states, i.e., divalent- and trivalent-like states of Eu-ions exist in the compound. The possible reason for the observed heterogeneous valency vis-a-vis the variation in the chemical environment and the number of nearest-neighbor B atoms surrounding the Eu-ions has been discussed. Our results demonstrate that B incorporation in such Eu-based cubic intermetallic compounds leads to a situation where heterogeneous-valence state of Eu-ions is an energetically favorable ground state. - Highlights: > Intermetallic compound Ce{sub 0.5}Eu{sub 0.5}Pd{sub 3}B{sub 0.5} crystallizes in a single phase. > Eu-ions in Ce{sub 0.5}Eu{sub 0.5}Pd{sub 3}B{sub 0.5} are charge-ordered compared to +2.3 valency in Ce{sub 0.5}Eu{sub 0.5}Pd{sub 3}. > B incorporation makes charge-ordered state of Eu-ions energetically more favorable. > Nearest-neighbor chemical environment affects the Eu valency.

Effect of Eu magnetism on the electronic properties of the candidate Dirac material EuMnBi2

Science.gov (United States)

May, Andrew F.; McGuire, Michael A.; Sales, Brian C.

2014-08-01

The crystal structure and physical properties of the layered material EuMnBi2 have been characterized by measurements on single crystals. EuMnBi2 is isostructural with the Dirac material SrMnBi2 based on single-crystal x-ray diffraction, crystallizing in the I4/mmm space group (No. 139). Magnetic susceptibility measurements suggest antiferromagnetic (AFM) ordering of moments on divalent Eu ions near TN=22 K. For low fields, the ordered Eu moments are aligned along the c axis, and a spin flop is observed near 5.4 T at 5 K. The moment is not saturated in an applied field of 13 T at 5 K, which is uncommon for compounds containing Eu2+. The magnetic behavior suggests an anisotropy enhancement via interaction between Eu and the Mn moments that appear to be ordered antiferromagnetically below ≈310 K. A large increase in the magnetoresistance is observed across the spin flop, with absolute magnetoresistance reaching ≈650% at 5 K and 12 T. Hall effect measurements reveal a decrease in the carrier density below TN, which implies a manipulation of the Fermi surface by magnetism on the sites surrounding the Bi square nets that lead to Dirac cones in this family of materials.

Luminescence properties of different Eu sites in LiMgPO4:Eu2+, Eu3+

The effect of temperature on the luminescence properties of LiMgPO 4 doped with Eu 3+ and Eu 2+ are presented. Depending on the excitation wavelength, luminescence spectra consist of two distinct broad emission bands peaking at 380 nm and 490 nm related to 4f 6 5d 1  → 4f 7 ( 8 S 7/2 ) luminescence of Eu 2+ and to europium-trapped exciton, respectively, and/or several sharp lines between the 580 nm and 710 nm region, ascribed to the 5 D 0  →  7 F J (J = 0, 1, 2, 3 and 4) transitions in Eu 3+ . To explain all the features of the Eu 2+ and Eu 3+ luminescence we discussed the existence of two different Eu sites substituting for Li + , with short and long distance compensation. The evident effect of increasing the intensity of the Eu 2+ luminescence with increasing temperature was observed. It was considered that the charge compensation mechanism for Eu 3+ and Li + as well as Eu 2+ replacing Li + in the LiMgPO 4 is a long distance compensation that allows for the existence of some of the europium ions either as Eu 3+ at low temperature or as Eu 2+ at high temperature. We concluded that Eu 2+ in the Li + site with long distance compensation yields only 4f 6 5d 1  → 4f 7 luminescence, whereas Eu 2+ in the Li + site with short distance compensation yields 4f 6 5d 1  → 4f 7 luminescence and europium-trapped exciton emission.

An evaluation of possible EU air transport emissions trading scheme allocation methods

International Nuclear Information System (INIS)

Morrell, Peter

2007-01-01

The European Commission has been requested by member states to study the incorporation of air transport into their existing emissions trading scheme (ETS). Only CO 2 is to be included, at least initially. This paper focuses on the method of allocation of emissions permits in the EU context. It has been assumed here that the EU ETS will be applied only to intra-EU flights and that airlines will be the entities selected for implementation. Three UK airlines were selected to evaluate three main types of allocation: grandfathering, auctioning and benchmarking. The airlines were representative of the three major airline business models: network, low-cost carrier and charter/leisure. Based on 2003/2004 aircraft/engine type and operating data, the per passenger impact of each allocation option was analysed for each airline. A new benchmarking approach is proposed that takes into account both the landing and take-off (LTO) cycle and per kilometre emissions: this avoids penalising shorter sector operators and focuses on the damage caused by aircraft and their engines and not on passengers.

The effectivity of the European emission trading system (EU-ETS) with respect to the reduction of greenhouse gas emissions based essentially on the quantity of the emission caps. The regional, sectorial and temporal boundaries of this system as well as the regulations covering international flexible mechanisms and banking have to be considered in the evaluation of the effectivity of the EU-ETS. Under this aspect, the authors of the contribution under consideration discuss the advantages and disadvantages of the different variants of adjustment. First of all, the criteria for an identification of a possible justified needs of adaptation are investigated. Furthermore, the authors discuss the question about suitable points in time for an intervention.

To what extent are EU steel companies susceptible to competitive loss due to climate policy?

International Nuclear Information System (INIS)

Okereke, Chukwumerije; McDaniels, Devin

2012-01-01

In recognition of their competitive vulnerability, a set of special rules have been devised for managing sectors such as iron and steel within the EU ETS. Under these rules, the EU steel sector has received free allocations in excess of their compliance needs to now, and will continue to receive some free allowances up to 2020. However, perceptions of the sector's competitive vulnerability have been largely based on inherently hypothetical analyses which rely heavily on counterfactual scenarios and abatement cost estimates often provided by firms themselves. This paper explores how the three largest steel firms in the EU (AcerlorMittal, Corus, and ThyssenKrupp) have sought to strategically exaggerate their vulnerability to carbon pricing to the effect of an inefficient policy outcome. We conduct a qualitative assessment of two of the key narratives underpinning the competitive vulnerability argument of EU steel companies – lack of abatement opportunities and inability to pass through cost increases – based on interviews, case studies, and publicly available data. We find that these arguments provide only partial and weak justifications for competitive loss and preferential treatment under the EU ETS. The strategy however remains successful due to information asymmetry and the peculiar political economy of EU climate regulation. - Highlights: ► We evaluate carbon leakage and vulnerability claims to climate policy by EU Steel companies. ► We find these claims are exaggerated and form key part of companies' climate political strategy. ► The success of this strategy implicates information asymmetry and the broader political economy of regulation within the EU. ► It has proved successful in helping the sector achieve free emission allocations in the EUETS.

The one word that best describes the spirit of the EuCARD ’13 event (see here) that took place from 10 to 14 June at CERN is "collaboration". The event brought together more than 180 accelerator specialists from all over the world to celebrate the conclusion of the EuCARD project and to kick off its successor, EuCARD-2.   EuCARD-2 brings a global view to particle accelerator research in order to address challenges for future generations of accelerators. The project officially began on 1 May 2013 and will run for four years. With a total budget of €23.4 million, including an €8 million EU contribution, it will build upon the success of EuCARD and push it into an even more innovative regime. EuCARD-2 aims to significantly enhance multidisciplinary R&D for European accelerators and will actively contribute to the development of a European Research Area in accelerator science. This will be accomplished by promoting complementary expertise, cross-d...

Stochastic carbon sinks for combating carbon dioxide emissions in the EU

International Nuclear Information System (INIS)

Gren, Ing-Marie; Carlsson, Mattias; Elofsson, Katarina; Munnich, Miriam

2012-01-01

This paper carries out numerical calculations on the potential of carbon sinks in the EU Emissions Trading Scheme (ETS) and national commitments under conditions of stochastic carbon dioxide emissions from fossil fuels and carbon sequestration by forests. Chance constraint programming is used to analyze the role of stochastic carbon sinks for national and EU-wide compliance costs. The analytical results show that the inclusion of the carbon sink option can reduce costs for low enough marginal cost and risk discount, but also that costless carbon sinks as by-products from forestry are not part of a cost-effective solution under a high reliability concern. Cost savings are reduced due to risk discounting under a reliability concern, in particular when assigning Chebyshev's inequality as compared with a normal probability distribution. It is also shown that the supply of forest sinks on the market depends on the differences in marginal abatement cost between the trading and the non-trading sectors, and in risk discounting between achievements of the ETS cap and the national commitment. Relatively low marginal abatement cost in the non-trading sector and high risk discounting of national commitment achievements increase the supply of sinks in the market and, hence, reduces the equilibrium price. The empirical application illustrates the importance of risk discounting for the magnitude of cost savings obtained from introducing forest carbon sinks in the EU ETS and national commitments.

EuO and Gd-doped EuO thin films. Epitaxial growth and properties

International Nuclear Information System (INIS)

Sutarto, Ronny

2009-01-01

Europium oxide (EuO) based materials exhibit a wealth of spectacular phenomena, including half-metallic ferromagnetism, metal-insulator transition, colossal magneto-resistance, large magneto-optical Kerr effect, tunable ferromagnetic ordering temperatures, and large and long-lived photo-induced conductivity. These extraordinary properties make EuO an ideal candidate for implementation in device applications, in particular, for spintronics. Most of the work in the past has been carried out on bulk EuO, but for device applications it is preferred to have the EuO in thin lm form. A urry of studies have therefore emerged in the last decade in order to explore a wide variety of preparation routes and to investigate the properties of the resulting EuO thin films. A recent highlight is the demonstration that doped EuO films can be fabricated on Si and GaN, thereby exhibiting the expected spin-polarized transport effects. Nevertheless, it is still far from a trivial task to prepare EuO thin films with well de ned properties. For bulk EuO, it is already known that stoichiometry is the key issue, and that the presence of small amounts of defects or impurities quickly lead to very large deviations of the material properties. In fact, to make bulk EuO to be stoichiometric one needs temperatures as high as 1800 C. It is obvious that such high temperatures are not compatible with device engineering processes. The preparation of thin films must therefore involve much lower temperatures, preferably not higher than 400-500 C. The consequences are very dear. It turned out that many of the recent studies on EuO thin films are suffering from sample quality problems, due to the presence of, e.g., trivalent Eu species (Eu 3 O 4 , Eu 2 O 3 ), oxygen vacancies, or even Eu metal clusters. Controlled doping of the EuO with trivalent rare-earth ions is also not trivial, since most often even the actual doping concentrations were not known. In fact, one could also question in this respect the

Europium oxide (EuO) based materials exhibit a wealth of spectacular phenomena, including half-metallic ferromagnetism, metal-insulator transition, colossal magneto-resistance, large magneto-optical Kerr effect, tunable ferromagnetic ordering temperatures, and large and long-lived photo-induced conductivity. These extraordinary properties make EuO an ideal candidate for implementation in device applications, in particular, for spintronics. Most of the work in the past has been carried out on bulk EuO, but for device applications it is preferred to have the EuO in thin lm form. A urry of studies have therefore emerged in the last decade in order to explore a wide variety of preparation routes and to investigate the properties of the resulting EuO thin films. A recent highlight is the demonstration that doped EuO films can be fabricated on Si and GaN, thereby exhibiting the expected spin-polarized transport effects. Nevertheless, it is still far from a trivial task to prepare EuO thin films with well de ned properties. For bulk EuO, it is already known that stoichiometry is the key issue, and that the presence of small amounts of defects or impurities quickly lead to very large deviations of the material properties. In fact, to make bulk EuO to be stoichiometric one needs temperatures as high as 1800 C. It is obvious that such high temperatures are not compatible with device engineering processes. The preparation of thin films must therefore involve much lower temperatures, preferably not higher than 400-500 C. The consequences are very dear. It turned out that many of the recent studies on EuO thin films are suffering from sample quality problems, due to the presence of, e.g., trivalent Eu species (Eu{sub 3}O{sub 4}, Eu{sub 2}O{sub 3}), oxygen vacancies, or even Eu metal clusters. Controlled doping of the EuO with trivalent rare-earth ions is also not trivial, since most often even the actual doping concentrations were not known. In fact, one could also question in

Electronic transport through EuO spin-filter tunnel junctions

KAUST Repository

Jutong, Nuttachai

2012-11-12

Epitaxial spin-filter tunnel junctions based on the ferromagnetic semiconductor europium monoxide (EuO) are investigated by means of density functional theory. In particular, we focus on the spin transport properties of Cu(100)/EuO(100)/Cu(100) junctions. The dependence of the transmission coefficient and the current-voltage curves on the interface spacing and EuO thickness is explained in terms of the EuO density of states and the complex band structure. Furthermore, we also discuss the relation between the spin transport properties and the Cu-EuO interface geometry. The level alignment of the junction is sensitively affected by the interface spacing, since this determines the charge transfer between EuO and the Cu electrodes. Our calculations indicate that EuO epitaxially grown on Cu can act as a perfect spin filter, with a spin polarization of the current close to 100%, and with both the Eu-5d conduction-band and the Eu-4f valence-band states contributing to the coherent transport. For epitaxial EuO on Cu, a symmetry filtering is observed, with the Δ1 states dominating the transmission. This leads to a transport gap larger than the fundamental EuO band gap. Importantly, the high spin polarization of the current is preserved up to large bias voltages.

EU climate policy impact in 2020. With a focus on the effectiveness of emissions trading policy in an economic recession scenario

PBL's Environmental Balance 2009 provides information on the current status and trends of environmental and climate policies. Ecofys contributes to the climate policy section of the report by developing the following three indicators: (1) ex-post and ex-ante policy impacts until 2020 at EU level (wedge diagram); (2) business-as-usual emissions of EU ETS sectors until 2020, revised for the current economic recession; (3) a latest literature review of EUA (EU emission allowances) price band expected until 2020. Based on the latter two analyses, a brief note on the impact of the current economic recession on the effectiveness of the EU emission trading scheme until 2020 is presented.An economic recession of two years or longer will considerably decrease the effectiveness of the Emissions Trading Scheme (ETS) in stimulating low-carbon technologies. In order to meet EU climate targets in the longer term, new governmental policies will be needed to compensate for this.

The EU Decarbonisation Roadmap 2050—What way to walk?

Hübler, Michael; Löschel, Andreas

2013-01-01

We carry out a detailed computable general equilibrium (CGE) analysis of the EU Decarbonisation Roadmap 2050 on a macroeconomic and on a sectoral level. Herein, we study a Reference scenario that implements existing EU policies as well as 3 unilateral and 3 global climate action scenarios. We identify global climate action with international emissions trading and the full equalisation of CO 2 prices across all (EU) sectors as an economically reasonable policy option to avoid additional costs of the Decarbonisation Roadmap to a large extent. This policy option may include CDM (Clean Development Mechanism in the sense of ‘where’-flexibility) in an extended form if there are countries without emissions caps. Moreover, we identify diverse sectoral effects in terms of output, investment, emissions and international competitiveness. We conclude that the successful realisation of the EU Decarbonisation Roadmap probably requires a wise and joint consideration of technology, policy design and sectoral aspects. - Highlights: ► We extend the CGE model PACE until 2050 and include energy technologies. ► We assess the newest EU Decarbonisation Roadmap in six policy scenarios. ► Global action with ETS and CDM credits from non-participants create low(est) costs. ► Mitigation costs can strongly increase at CO 2 reductions around 80%. ► The policy effects vary strongly across EU sectors

Key Questions for Achieving EU Emission Reductions without Abandoning Other Energy Goals

International Nuclear Information System (INIS)

Stang, G.

2014-01-01

What considerations must be addressed to ensure that efforts to achieve the EU's new 2030 emissions and renewables targets are compatible with the other energy goals of the EU and its member states: energy security, and energy affordability? How should these other energy goals be addressed when pursuing energy efficiency improvements, upgrading electricity systems to handle different renewable energy sources, and developing policies to reduce overall CO2 emissions? Markets have been defined as being central to achieving all of Europe's energy goals - both the creation of an EU internal energy market and the use of the Emissions Trading System (ETS) to allow a market for managing a portion of the continent's greenhouse gas emissions. But once these markets are in place and operational, there will still be great variances among the goals, instruments, and level of market integration available for the different countries and regions of Europe. Choosing the most cost effective mechanisms for pursuing the new goals will require effective use of the flexibility that is available - an improved ETS, tradable national targets for non-ETS emissions, and a rapidly widening array of cost-effective renewable energy options. Sufficient use of this flexibility should facilitate the flow of energy investments toward energy system improvements where there is low-hanging fruit - anywhere in the continent - without requiring that local or continental energy security goals be sacrificed.

Business interest of Gazprom in the EU-27 in 2007

Meijknecht, J.

2008-04-01

Gazprom is an important supplier of gas to the EU. Liberalisation of the EU gas market has also influenced the gas relations with Russia and the way the Russian Gas company Gazprom is securing its interest in this internal EU market. From a relationship of bilateral gas contracts with EU member states and their companies before gas market liberalisation, a new approach to secure its market share is beginning to evolve. The positioning of Gazprom in the EU market has raised concerns of EU policy makers. There is some trepidation that the investment strategy of Gazprom in the EU gas market will lead to a position of market dominance in an increasingly import dependent EU market. The discussion on Gazprom's market strategy needs to be fed with factual information on its activities and it is exactly what this new report is providing because information on the activities of Gazprom in the various member states' gas sector was incomplete. In this factual report in Dutch, the author presents a comprehensive oversight and characterisation of Gazprom's downstream assets in the EU-27. Through four layers - long-term contracts, company stakes, asset swaps and political support - a detailed insight is given in Gazprom's downstream activities in the EU-27. [nl

EU COMPARISON OF VAT

Full Text Available VAT is one of the newest tools of the global economy and is widely adopted in most of the countries. For EU Member States is required not only the existence of VAT, but also that its main characteristics to be uniformly implemented. This should facilitate intra-Community transactions, but in practice does not as there are many local variations which can lead to costly errors and penalties. The objective of this paper is to collate data about the main characteristics of VAT in EU Member States and to highlight the key differences between them. This survey shows that there continue to be opportunities and risks for businesses trading cross border, as a result of differences in application of Community legislation on VAT. This led to the necessity of VAT reform. On this basis, the Commission adopted on the end of the last year a Communication on the future of VAT. This sets out the fundamental characteristics that must underlie the new VAT regime, and priority actions needed to create a simpler, more efficient and more robust VAT system in the EU.

Evaluation of policy options to reform the EU Emissions Trading System. Effects on carbon price, emissions and the economy

Energy Technology Data Exchange (ETDEWEB)

Verdonk, M.; Brink, C.; Vollebergh, H.; Roelfsema, M.

2013-04-15

The EU Emissions Trading System (EU ETS) is a key instrument of EU climate policy, providing a clear reduction pathway for CO2 emissions. The current carbon price (of about 3 euros per tonne of CO2, April 2013) is much lower than previously expected (which was around 30 euros) and is likely to remain low for a long time. This fuels doubts about whether the ETS will remain a key policy instrument in the long term. Such doubts also increase investment uncertainty, which is likely to have a negative impact on further investments in low-carbon technologies needed for a low-carbon economy in 2050. In November 2012, the European Commission put forward six options for a more structural reform of the EU ETS. The proposed options vary from reducing the cap and expanding the ETS to include other sectors, to strengthening the ETS by measures directly affecting allowance prices. The Dutch Ministry of Infrastructure and the Environment (IenM) asked the PBL Netherlands Environmental Assessment Agency to assess the impact of these options. Four categories of options for reforming the ETS were evaluated: (1) reducing the supply of emission allowances; (2) expanding the ETS by including other sectors; (3) a minimum price for auctioned allowances; and (4) combining ETS with a carbon tax. Recently, the European Parliament voted against the European Commission's proposal to temporarily set aside emission allowances. In an earlier assessment of this proposal, PBL concluded that the impact of this backloading proposal on CO2 prices is likely to be limited, because the total amount of allowances up to 2020 would remain unchanged. All options analysed would reduce emissions and cause the emission price to increase. A minimum price on carbon, however, would provide the best opportunity to make the ETS more robust against unforeseen events, such as a further deterioration of the economy. Such a minimum price would result in more emission reductions if abatement proves to be cheaper

An independent peer review of the study 'ex-post investigation of cost pass-through in the EU ETS: an analysis of six sectors'

International Nuclear Information System (INIS)

2016-05-01

This report provides a Peer review of the study 'Ex-post Investigation of Cost Pass- Though in the EU ETS: an analysis of six sectors' produced by CE-Delft and Oeko Institut and published by the EU Commission in November 2015. The study of CE-Delft and Oeko Institut (2015) investigates carbon costs pass-through across iron and steel, refineries, cement, organic basic chemicals, fertilizer, and glass. It also provides estimates of these cost pass-through rates of roughly around 100% for petrochemicals, 80-100% for petrol above 100% for diesel and gas-oil. Our Peer review (on refineries and organic basic chemicals) concludes that the results of the study cannot be used as direct policy recommendations due to the following three main limitations. The robustness of the econometric results is not clearly grounded: the claims of the study are only supported at a low confidence level (the chosen confidence interval was 10% while sound econometric practice would require at least 5%). Moreover detailed analysis shows that the hypothesis of a cost pass-through is significant (at 10%) only for some products and for some EU countries. The results are heterogeneous and not representative of a conclusion at the EU level for either sector. The quantitative estimates on the cost pass-through rates are obtained through a simple accounting relationship between input costs and output prices. Economic practice would rather use an explicit price formation model allowing for such factors as trade intensity, market structure and concentration, heterogeneity of competitors, etc... Some of these factors are marginally analyzed in the study without providing clear conclusions. Indeed, without any in-depth statistical analysis, the study cannot establish a statistical significant relationship between market shares and cost pass-through rates. Other explanatory variables such as the role of EUA price volatility and the macro-economic environment should also have been considered

This paper responds to the EU‟s „call for action‟ towards addressing the issue of climate change – a key priority for the European Commission in the 2030 policy perspective. The topic is addressed through a focus group that seeks to identify and disseminate possible approaches through which the EU can leverage its international „actorness‟ in negotiating a straightforward and binding global agreement for action in climate change mitigation. The focus group involves a sample of students, beneficiaries of an environmentally focused Jean Monnet teaching module (TAG-EU.

A comparison is presented between Eu implanted and Eu in situ doped GaN thin films showing that two predominant Eu sites are optically active around 620 nm in both types of samples with below and above bandgap excitation. One of these sites, identified as a Ga substitutional site, is common to both types of Eu doped GaN samples despite the difference in the GaN film growth method and in the doping technique. High-resolution photoluminescence (PL) spectra under resonant excitation reveal that in all samples these two host-sensitized sites are in small amount compared to the majority of Eu ions which occupy isolated Ga substitutional sites and thus cannot be excited through the GaN host. The relative concentrations of the two predominant host-sensitized Eu sites are strongly affected by the annealing temperature for Eu implanted samples and by the group III element time opening in the molecular beam epitaxy growth. Red luminescence decay characteristics for the two Eu sites reveal different excitation paths. PL dynamics under above bandgap excitation indicate that Eu ions occupying a Ga substitutional site are either excited directly into the 5 D 0 level or into higher excited levels such as 5 D 1 , while Eu ions sitting in the other site are only directly excited into the 5 D 0 level. These differences are discussed in terms of the spectral overlap between the emission band of a nearby bound exciton and the absorption bands of Eu ions. The study of Eu doped GaN quantum dots reveals the existence of only one type of Eu site under above bandgap excitation, with Eu PL dynamics features similar to Eu ions in Ga substitutional sites

Full Text Available The paper deals with the EU aid concerning to improved the economic situation from developing countries. Therefore, the aim of this research is to identify how EU states contribute to helping poor countries, members of the World Trade Organization. For the beginning, we define the EU’position before, during and after the Doha Round – a round of WTO multilateral trade negotiations. Moreover, we analyse the development dimension, focusing on countries „marginalized” until early of XXI century in terms of international trade, because this represents the idea-axis of the Doha Round. In this context, the EU – one of the leading global commercial players and a key member of the institution mentioned above – has set several objectives to achieve the basic goal of negotiations and several ways to support developing countries. To conclude, we propose to define the key points of the European aid for least developed and developing countries.

Spin-polarized, orbital-selected hole gas at the EuO/Pt interface

Using density functional theory, we explore the magnetic behavior of a EuO/Pt heterostructure. The calculations suggest that the heterostructure could be used as a spin filter, as the Schottky barriers in the spin-up and spin-down channels are calculated to be 1.42 and 2.18 eV, respectively. We discover that the interfacial and second layer of EuO, both have a reduced magnetic moment, while the remainder of the oxide maintains bulk magnetization. These first two layers support a localized mid-gap electronic state that protects the remainder of EuO from losing charge into the large work function Pt, which in turn results in the magnetic moment reduction. Our calculations are consistent with recent experimental results of Barbagallo et al. [Phys. Rev. B 84, 075219 (2011)].

EU Emission Allowances and the stock market Evidence from the electricity industry

International Nuclear Information System (INIS)

Oberndorfer, Ulrich

2009-01-01

This paper constitutes - to our best knowledge - the first econometric analysis on stock market effects of the EU Emission Trading Scheme (EU ETS). Our results suggest that EU Emission Allowance (EUA) price developments matter to the stock performance of electricity firms: EUA price changes and stock returns of the most important European electricity corporations are shown to be positively related. This effect does not work asymmetrically, so that stock markets do not seem to react differently to EUA appreciations in comparison to depreciations. The carbon market effect is shown to be both time- and country-specific: It is particularly strong for the period of EUA market shock in early 2006, and differs with respect to the countries where the electricity corporations analysed are headquartered. Stock market reactions to EUA volatility could not be shown. (author)

Renewable energies in the EU-Accession States

International Nuclear Information System (INIS)

Reiche, Danyel

2006-01-01

The aim of this article is to discuss obstacles and success conditions for renewable energy sources in the EU-Accession States and to compare them with the framework in the EU-15. Besides the ten states which will join the EU in 2004, Bulgaria and Romania which will probably join in 2007 as well as Turkey are analysed. Most of these countries have had a century-long tradition in the utilisation of RES, primarily in biomass and hydropower. However, the communist regimes were convinced of the superiority of large-scale systems and converted the energy sectors into centralised units. Due to this dominating belief system more decentralised applications such as installations using renewable energies had to close. One crucial driving force for future renewable energy development in the Accession States comes from the stipulations set by the EU. The EU-Directive on the promotion of electricity produced from RES gives the new EU-members targets for their RES-development until 2010. Due to the Directive many Accession States have already begun to pay more attention to the topic and to introduce more systematic policies. Six of the Accession States have introduced minimum tariffs which were one of the main success conditions (besides a stable and sound investment programme as well as favourable background conditions) in the leading wind energy countries Germany and Spain. Beside the external pressure by the EU and other international obligations other driving forces such as the path dependencies in the national energy policies (degree of coal, oil and gas exploitation, nuclear power use, import dependency), the political support schemes for renewable energies, possibilities of obtaining external financial support and the cognitive environment are discussed. Finally similarities and differences between EU-15 and Accession States are worked out

Policy options to improve the effectiveness of the EU emissions trading system: A multi-criteria analysis

International Nuclear Information System (INIS)

Clò, Stefano; Battles, Susan; Zoppoli, Pietro

2013-01-01

This paper considers several policy options which have been proposed to improve the functioning of the ETS. These options require an intervention either on the ETS cap (−30% target, set-aside, carbon central bank, long-term target) or on the carbon price (European and national price floor). We analyse the impact of each policy on the ETS carbon price and emissions. A multi-criteria evaluation method is applied to compare the policy options against a plurality of environmental, economic and procedural criteria. We find that the final ranking depends on the goals to be achieved, i.e., the relative weights attributed to the criteria. When policymakers want mainly to support the carbon price both in the short and long-run, while improving ETS flexibility and harmonization, the CCB and the EU price floor are, respectively ranked as first and second-best options. As the preference for environmental and implementation goals gradually increases, the position of the EU price floor and CCB options tend to invert. The −30% target should be adopted when reducing emissions is the priority goal, while a national price floor is the worst option, in this case. Nevertheless, self-interested States looking for a relatively quick, feasible solution, may find it optimal. - Highlights: ► A multi-criteria analysis is adopted to compare policy options to improve the ETS effectiveness. ► An ETS cap reversible adjustment by a carbon central bank is the first-best option. ► The establishment of a EU-wide price floor would represent a second-best solution. ► A national price floor is the worst option but self-interest states may find it optimal. ► A post-2020 target is not a mutually exclusive option and should be set

Experimental mesocosms are valuable tools to fill the gap between highly controlled/replicated lab experiments and uncontrolled/non-replicated natural environments such as rivers, lakes and oceans. WWW.MESOCOSM.EU is an open web-portal for leading aquatic mesocosm facilities around the world. It was created within the FP7 EU-project MESOAQUA (A network of leading MESOcosm facilities to advance the studies of future AQUAtic ecosystems from the Arctic to the Mediterranean). The goal of the portal is to increase international knowledge about existing mesocosm facilities, including information on locations, environment, equipment, contacts, research opportunities and mesocosm-based publications. MESOCOSM.EU specifically aims to be a tool to enhance the quality of research by facilitating international cooperative network building, announcement of new research initiatives, transfer of best practice, and dissemination of knowledge, public information and press releases. As an open platform for all aquatic ecosystem scale science (marine and freshwater), MESOCOSM.EU aims to fill the lack of a centralized, coordinating virtual infrastructure for international aquatic mesocosm research, from the mountains to the ocean and from polar to tropical regions.

Des resultats obtenus recemment au Laboratoire National des Champs Magnetiques Intenses a Grenoble sur La1.7Eu0.2Sr0.1 CuO4, La1.675Eu0.2Sr0.125CuO 4, La1.64Eu0.2Sr0.16CuO4, La1.74Eu0.1Sr0.16CuO4 et La 1.4Nd0.4Sr0.2CuO4 sont analyses. Une attention particuliere est accordee aux equations de la theorie semi-classique du transport et leur validite est verifiee. La procedure experimentale et les materiaux utilises pour concevoir les montages de mesures sont expliques en detail. Enfin, un chapitre est dedie a l'explication et l'interpretation des resultats de transport thermoelectrique sur YBa2Cu3O6+delta publies au cours de l'hiver 2010 dans les revues Nature et Physical Review Letters. Les donnees d'effet Seebeck dans les echantillons de La 1.8-x,Eu0.2SrxCuO 4, ou un changement de signe est observe, permettent de conclure a la presence d'une poche d'electrons dans la surface de Fermi qui domine le transport a basse temperature dans la region sous-dopee du diagramme de phase. Cette conclusion est similaire a celle obtenue par des mesures d'effet Hall dans YBa 2Cu3O6+delta et elle cadre bien dans un scenario de reconstruction de la surface de Fermi. Les donnees d'effet Nernst recueillies indiquent que la contribution des fluctuations supraconductrices est limitee a un modeste intervalle de temperature au-dessus de la temperature critique.

The failure of intergovernmentalism in tackling the EU crisis and the European Parliament’s initiative

Directory of Open Access Journals (Sweden)

Castaldi Roberto

2016-12-01

Full Text Available The EU is facing a multi-faceted, existential, crisis; it is an economic and social crisis in some countries, a political and cultural crisis all over the EU and a geopolitical crisis at the international level. National governments have taken the lead in the crisis management of the EU: the European Council has become the dominant institution and the intergovernmental method has come back into fashion. But intergovernmentalism has failed: since 2008 the crisis keeps getting worse. Intergovernmentalism is leading towards the EU’s disintegration. Among many voices to save the EU, it is interesting that the supranational institutions, and particularly the Parliament, are taking on themselves the responsibility to take the initiative and indicate a possible way forward for the Union.

151 Eu nuclear resonant inelastic scattering of Eu 3 Pd 20 Ge 6 . The Eu partial phonon density of states (DOS) in Eu 3 Pd 20 Ge 6 are investigated using 151 Eu nuclear resonance inelastic scattering (NRIS). 151 Eu NRIS was carried out at BL09XU of SPring-8. Significant temperature dependence was found in the partial phonon DOS. Judging from the valence change at the Eu 4a site and the comparison with the ab initio calculation of Eu 3 Pd 20 Ge 6 , the change of the Eu DOS is caused by the electronic states. On the other hand, significant acoustic contribution was found even at the guest site of the Eu ones. In addition, slower average velocity than transverse sound velocity was obtained by Eu partial phonon DOS. Considering that heat is carried by the acoustic phonon in materials, the present results demonstrate that the moderate thermal insulation in Eu 3 Pd 20 Ge 6 is connected with the observation of slow average sound velocity at the Eu sites.

The concept of family in the EU free movement law

Directory of Open Access Journals (Sweden)

Janićijević Dejan

2014-01-01

Full Text Available This paper examines the concepts of spouse, civil partner and partner in European Union (EU law, particularly in regulations referring to the free movement of persons, criticizing the unharmonized approach to defining family in this context. It argues that the narrow interpretation of the term spouse could lead to discrimination on the grounds of sexual orientation. Likewise, grounding free movement rights of civil partners on host state recognition of such partnerships could lead to the same result, which is not compatible with the equality principle in the EU law. The position of unmarried or unregistered partners is also considered; in particular, the paper analyses the requirement to duly attest durability of the relationship and its impact on the same-sex partners wishing to immigrate to a Member State. The author holds that it is necessary to reconsider the law in this area and adjust it to the EU's efforts to eliminate discrimination on the grounds of sexual orientation.

EU focus on climate change

International Nuclear Information System (INIS)

2002-01-01

Faced with the mounting evidence of the harmful effects of climate change, the European Union is convinced that the world must take urgent action to tackle the problem. That is why the EU has been at the forefront of international efforts to deal with climate change for well over a decade. The EU is convinced that the status quo is simply not an option. Without urgent, concerted action, the problem will continue to get worse with potentially disastrous consequences. That is why the European Union has consistently taken the lead in international moves to tackle climate change and why it will continue to develop this strategy for as long as it takes to guarantee a world for ourselves and our children where everyone can grow, breathe and live in safety

White-emission in single-phase Ba2Gd2Si4O13:Ce3 +,Eu2 +,Sm3 + phosphor for white-LEDs

Jiang, Xiumin; Zhang, Yuqian; Zhang, Jia

2018-03-01

To develop new white-light-emitting phosphor, a series of Ce3 +-Eu2 +-Sm3 + doped Ba2Gd2Si4O13 (BGS) phosphors were prepared by the solid-state reaction method, and their photoluminescence properties were studied. The Ce3 + and Eu2 + single-doped BGS show broad emission bands around in the region of 350-550 and 420-650 nm, respectively. By co-doping Ce3 +-Eu2 + into BGS, the energy transfer (ET) from Ce3 + to Eu2 + is inefficient, which could be due to the competitive absorption between the two activator ions. The Sm3 +-activated BGS exhibits an orangey-red emission in the region of 550-750 nm. To achieve white emission, the BGS:0.06Ce3 +,0.04Eu2 +,ySm3 + (0 ≤ y ≤ 0.18) phosphors were designed, in which the ET from Ce3 +/Eu2 + to Sm3 + was observed. The emission color can be tuned by controlling the Sm3 + concentration, and white emission was obtained in the BGS:0.06Ce3 +,0.04Eu2 +,0.06Sm3 + sample. The investigation of thermal luminescence stability for the typical BGS:0.06Ce3 +,0.04Eu2 +,0.06Sm3 + sample reveals that the emission intensities of both Eu2 + and Sm3 + demonstrate continuous decrease but the Ce3 + emission is enhanced gradually with increasing temperature. The corresponding reason has been discussed.

The EU Emissions Trading Scheme. Allowance Prices, Trade Flows, Competitiveness Effects

International Nuclear Information System (INIS)

Klepper, G.; Peterson, S.

2004-03-01

The upcoming European Emissions Trading Scheme (ETS) is one of the more controversial climate policy instruments. Predictions about its likely impact and its performance can at present only be made to a certain degree. As long as the National Allocations Plans are not finally settled the overall supply of allowances is not determined. In this paper we will identify key features and key impacts of the EU ETS by scanning the range of likely allocation plans using the simulation model DART. The analysis of the simulation results highlights a number of interesting details in terms of allowance trade flows between member countries, of allowance prices, and in terms of the role of the accession countries in the ETS

Banning banking in EU emissions trading?

International Nuclear Information System (INIS)

Schleich, Joachim; Ehrhart, Karl-Martin; Hoppe, Christian; Seifert, Stefan

2006-01-01

Admitting banking in emissions trading systems reduces overall compliance costs by allowing for inter-temporal flexibility: cost savings can be traded over time. However, unless individual EU Member States (MS) decide differently, the transfer of unused allowances from the period of 2005-2007 into the first commitment period under the Kyoto Protocol, i.e. 2008-2012, will be prohibited. In this paper, we first explore the implications of such a ban on banking when initial emission targets are lenient. This analysis is based on a simulation which was recently carried out in Germany with companies and with a student control group. The findings suggest that a EU-wide ban on banking would lead to efficiency losses in addition to those losses which arise from the lack of inter-temporal flexibility. Second, we use simple game-theoretic considerations to argue that, under reasonable assumptions, such a EU-wide ban on banking will be the equilibrium outcome. Thus, to avoid a possible prisoners' dilemma, MS should have co-ordinated their banking decisions

Three novel Eu(III) phosphor complexes, [Eu(HL)(OH2)2(C2H5OH)](NO3)2 (1), [Eu(HL)(Bpy)(NO3)2(EtOH)] (2) and [Eu(HL)(Phen)(NO3)2(H2O)] (3) (HL = (11E)-2-hydroxy-N/-((4-oxo-4H-chromen-3-yl)methylene)benzohydrazide; Bpy = 2,2/-bibyridyl and Phen = 1,10-phenanthroline) were prepared. Elemental, thermal, FT-IR and XRD methods were used to characterize their structural configuration. The HL behaves as a monoanionic tridentate ligand. The XRD analysis shows that the ligand and its Eu3+complexes are in nano domain. From fluorescence spectroscopy, all the prepared complexes are highly luminescent, having an impressive visual emission under UV excitation. The H2L and its Eu3+nano-complexes (1-3) were tested for their in vitro cytotoxicity against Ehrlich Ascites Carcinoma cell line (EAC). The Eu(III) nano-complexes (1-3) effectively inhibited EAC growth with IC50 value of 25 μM. The high antitumor activity of the Eu(III) nano-complexes (1-3) were attributed to its chemical structure, and nano size properties.

EU energy-intensive industries and emissions trading: losers becoming winners?

Energy Technology Data Exchange (ETDEWEB)

Wettestad, Joergen

2008-11-15

The EU Emissions Trading System (ETS) initially treated power producers and energy-intensive industries similarly, despite clear structural differences between these industries regarding pass through of costs and vulnerability to global competition. Hence, the energy-intensive industries could be seen as losing out in the internal distribution. In the January 2008 proposal for a reformed ETS post-2012, a differentiated system was proposed where the energy-intensive industries come out relatively much better. What is the explanation for the change taking place? Although power producers still have a dominant position in the system, the increasing consensus about windfall profits has weakened their standing. Conversely, the energy-intensive industries have become better organised and more active. This balance shift is first and foremost noticeable in several important EU-level stake holder consultation processes. Energy-intensive industries have, however, also successfully utilised the national pathway to exert influence on Brussels policy-making. Finally, growing fear of lax global climate policies and related carbon leakage has strengthened the case of these industries further. The latter dimension indicates that although energy-intensive industries have managed to reduce internal distribution anomalies, external challenges remain. (author). 9 refs

With regard to phosphor thermometry, the materials Y{sub 3}Al{sub 5}O{sub 12}:Eu (YAG:Eu) and YAlO{sub 3}:Eu (YAP:Eu) were synthesised and characterised in order to substitute the commonly used thermographic phosphor Y{sub 2}O{sub 3}:Eu, whose temperature sensitive luminescence lifetime exhibits a strong and most often undesirable cross-sensitivity to the oxygen concentration of the surrounding gas phase. The synthesis is outlined in detail and the crystallographic structure was characterised by X-ray diffraction. In a second step, the luminescence properties following pulsed UV laser excitation were determined. In this context, the emission spectra and the temperature lifetime characteristics were monitored. For Y{sub 3}Al{sub 5}O{sub 12}:Eu and YAlO{sub 3}:Eu, temperature sensitive ranges of 1000 K–1470 K and 850 K–1300 K were identified. Contrary to Y{sub 2}O{sub 3}:Eu, both materials do show much lower cross-sensitivities to the oxygen concentration of the surrounding gas phase. - Highlights: ► Y{sub 3}Al{sub 5}O{sub 12}:Eu and YAlO{sub 3}:Eu were synthesised and characterised. ► The synthesis is outlined and the crystallographic structure was characterised. ► Emission spectra and the temperature lifetime characteristics were monitored. ► Compared to Y{sub 2}O{sub 3}:Eu lower sensitivities to the oxyg. conc. of the gas phase emerged.

In this article I study the long-term evolution of the main categories of expenditure of the European Union (EU) budget (1984-2011). The aim is to assess the extent to which the EU is affected by a structural form of policy inertia, and to investigate the general pattern of policy stability...... and change in the EU in light of the two models of policy dynamics currently existing in the literature: the incrementalist model and the punctuated equilibrium model. The analysis of long series of original data extracted from the EU budget shows that EU policies do not evolve following an incrementalist...

Crisis of the EU Eastern Policy

Irina V. Bolgova

2014-01-01

Full Text Available The results of the Vilnius summit of the EaP project and the consequent Ukrainian crisis with major international effects make possible questioning about the eventual scenarios of the EU eastern politics and possible configurations ofinternational interactions. The article elaborates on the key elements and trends of the EU activities at the post-soviet space that are likely to frame the context of its further developments. The most visible trends analysed here are the extreme differentiation of bilateral relations within the EaP project alongside with the growing symbolism of official rhetoric and program practices of the European Union. As a result, we see the EU's intention to narrow the geographical and qualitative field of its activities on the eastern directionwith saving the shell of the EaP for nominal functioning. Such tactics is not likely to result in a drastic change of the model of conflict dependencies in the "shared neighbourhood". The article analyses key misperceptions of the actors involved in the complex of interactions in the region. The structure is complicated by the deepening and widening of Russia-lead Eurasian integration project. Current crisis of the EU eastern policy is considered to derive from the exaggeration of the value-based, normative aspect of the common foreign policy in general and will have the systemic consequences both for the European external actions and for its internal developments.

SrF 2 :Eu nanophosphors were successfully synthesized by the hydrothermal method. The structure of the nanophosphors was investigated with x-ray diffraction. The average crystallite size calculated using the Scherrer equation was in the range of 7.0 nm. The photoluminescence of Eu doped as-prepared SrF 2 nanophosphors were studied using different excitation sources. The samples showed emission from both the Eu oxidation states, Eu 2+ and Eu 3+ . At low Eu concentrations the emission from Eu 2+ centered at 416 nm was more dominant. While the narrow band of Eu 3+ emission intensity increased with an increase in the Eu concentration. High resolution x-ray photoelectron spectroscopy results indicated that the Eu was indeed in both Eu 2+ and Eu 3+ valance states. The presence of Eu 2+ and Eu 3+ in the system largely enhanced the response of the Eu 3+ under ultraviolet excitation. The time of flight-secondary ion mass spectrometry results suggested that the energy transfer between two ions was likely to occur. The relative photoluminescence intensity of the Eu 2+ rapidly decreased with an increasing laser beam irradiating time. This result would make the current Eu 2+ doped SrF 2 samples unsuitable candidates for several applications, such as white light-emitting diodes and wavelength conversion films for silicon photovoltaic cells. - Highlights: • SrF 2 : Eu nanophosphors were successfully synthesised (hydrothermal technique). • PL and XPS results showed enhanced absorption response of Eu 3+ UV excitation. • Eu concentrations more than 5 mol% improved fluorescence emission. • TOF-SIMS results suggested that the energy transfer from Eu 2+ to Eu 3+ is dominant

Complexation of Cucurbit(7)uril with Eu(III)

Cucurbiturils (CBs) CB(n)s are macrocyclic molecules with carbonyl groups at the portals, which bind cations through ion dipole interactions and the cavity which stabilize hydrophobic moieties. The size of the portal and the volume of the interior cavities of CB(n)s are dependent on the number of glycoluril units present in CBs. CBs are widely used as supramolecular host systems in applications, such as formation of supramolecular hydrogels, drug delivery systems. Though the binding of CBs with organic guest molecules have been studied extensively where as metal complexation studies are very few. In the present work, complexation studies of Cucurbit(7)uril (with seven glycouril units, CB7) with Eu(III) were carried out using fluorescence, UV-vis spectrophotometry. The stability constant for 1:1 complex CB7-Eu(III) complex determined by monitoring the change in CB7 UV- vis absorption spectra on addition of Eu(III) was found to be 2.99 ± 0.08. The fluorescence spectra of increasing ligand to metal ratio exhibited the increase in the intensity ratio of peak at 616 and 592 which is the measure of complexation of Eu(III) with CB7 and was used to deduce the stability constant and the value (2.82 ± 0.07) obtained was in good agreement with that obtained from UV vis spectroscopy. Further, the life time of Eu(III) ion, which increased with CB7 to Eu(III) ratio, was used to deduce number of water molecules around Eu(III) metal ion which were found to decrease from 9 to 3 thereby suggesting inner sphere complexation. The stability constant of CB7 with Eu(III) is one order of magnitude less than CB5, derived in separate study by authors. The smaller cavity of CB5 (2.4 A 0 ) favors its interactions with Eu(III) ion of comparable diameter (2.16 A 0 ) leading to higher stability constant compared to CB7 (5.4 A 0 ) having larger cavity

The Influence of Migration Crisis in Europe on EU-Turkey Relations

Directory of Open Access Journals (Sweden)

Pavel P. Timofeyev

2016-01-01

Full Text Available The paper examines the impact of the migration crisis in the EU on the European Union's relations with Turkey. It is shown that for a number of reasons, including a result of EU actions taken from 2011 to 2015, EU has experienced an influx of migrants on a number of routes from the Western to the Eastern Mediterranean. The largest of them fell on Turkey, which has tried to use this factor to exert pressure on the EU in order to obtain economic and political preferences. The author examines the development of the EU migration policy in the context of the crisis, its trying to bring Turkey to cooperate and difficult negotiations, which took place at the summits of the EU-Turkey at the end of 2015. There have been disagreements among the EU countries, and the time factor, which Turkey took advantage of, advancing conditions for the closure of borders to Europe for migrants. Facing the influx of migrants the EU had to agree with a number of conditions, though not with all. The author shows that the agreement reached by the country in March 2016 is not universal, and a number of issues important to the resolution of the crisis, are waiting to be decided upon. However, according to the author, the development of the current crisis can lead both to the reform of the migration and border policy within the EU, and to restarting relations with Turkey. Though guessing on possibilities on Turkey's entry to the EU in the near future is still premature.

Synthesis and tunable luminescent properties of Eu-doped Ca2NaSiO4F – Coexistence of the Eu2+ and Eu3+ centers

Directory of Open Access Journals (Sweden)

Mubiao Xie

Full Text Available Novel phosphors Ca2NaSiO4F:Eu were synthesized successfully by the conventional solid-state method in CO atmosphere, and their spectroscopic properties in UV−vis region were investigated. The photoluminescence properties show that Eu3+ ions were partially reduced to Eu2+ in Ca2NaSiO4F. As a result of radiation and re-absorption energy transfer from Eu2+ to Eu3+, both Eu2+ bluish-green emission at around 520 nm and Eu3+ red emission are observed in the emission spectra under the n-UV light excitation. Furthermore, the ratio between Eu2+ and Eu3+ emissions varies with increasing content of overall Eu. Because relative intensity of the red component from Eu3+ became systematically stronger, white light emission can be realized by combining the emission of Eu2+ and Eu3+ in a single host lattice under n-UV light excitation. These results indicate that the Ca2NaSiO4F:Eu phosphors have potential applications as a n-UV convertible phosphor for light-emitting diodes.

Spectrally Undiscerned Isomers Might Lead to Erroneous Determination of Water Exchange Rates of paraCEST Eu(III) Agents.

Science.gov (United States)

Cakić, Nevenka; Tickner, Ben; Zaiss, Moritz; Esteban-Gómez, David; Platas-Iglesias, Carlos; Angelovski, Goran

2017-07-17

We report a detailed study of the solution structure and water exchange rate of a Eu(III) complex with the cyclen-based ligand L 1 , containing (S)-2-(2-acetamido)-3-(4-(trifluoromethyl)phenyl)propanoate pendant arms at positions 1 and 7 of the cyclen ring and acetylglycinate pendants at positions 4 and 10. The EuL 1 complex was characterized by a combination of NMR and luminescence spectroscopy and density functional theory (DFT) calculations. The chemical exchange saturation transfer (CEST) spectra obtained at different temperatures and saturation powers present a CEST signal attributed to the coordinated water molecule. However, the spectra recorded at low temperatures (10 °C) and low saturation powers revealed the presence of two different species with coordinated water molecules having very similar chemical shifts. Determination of the water exchange rates of the coordinated water molecules was carried out by using the Bloch four-pool model that accounts for the presence of these isomers, and this model was compared to conventional methods for CEST quantification, namely the Omega plot and QUESP (quantification of exchange rate as a function of saturation power), which assume the presence of a single CEST active species. The results indicated that only the four-pool Bloch equations provide reasonable water exchange rates and activation parameters. Solution NMR studies and DFT calculations indicated that the two isomers present in solution correspond to the SS-Δ(λλλλ) and SS-Λ(δδδδ) isomers, which present capped square-antiprismatic (SAP) coordination environments. Additional NMR studies on the EuL 2 and EuL 3 complexes, which present four (S)-2-(2-acetamido)-3-(4-(trifluoromethyl)phenyl)propanoate or acetylglycinate pendant arms, respectively, confirm the results obtained for EuL 1 .

This result would make the current Eu{sup 2+} doped SrF{sub 2} samples unsuitable candidates for several applications, such as white light-emitting diodes and wavelength conversion films for silicon photovoltaic cells. - Highlights: • SrF{sub 2}: Eu nanophosphors were successfully synthesised (hydrothermal technique). • PL and XPS results showed enhanced absorption response of Eu{sup 3+} UV excitation. • Eu concentrations more than 5 mol% improved fluorescence emission. • TOF-SIMS results suggested that the energy transfer from Eu{sup 2+} to Eu{sup 3+} is dominant.

Climate and Energy Framework will have an impact, our study suggests that the ambition of EU and Member State policies is either a continuation of business as usual in terms of rates of progress, or is being dialed down in some cases. The EU and Member State policy should significantly revise their approach to decarbonization by refocusing on the key drivers of emissions in each sector. The EU's new Energy Union Governance Mechanism should be designed based on this principle and current proposals to implement the 2030 package should be adopted in the strongest possible form to put the EU back on track. The EU, in coordination with the Member States, should develop a suite of sectoral policies to complement the overarching emissions caps of the EU ETS and non-ETS sectors

The need and necessity of an EU-wide renewable energy target for 2030. Discussion paper

In 2020, some leading EU energy and climate policies will expire. At present, the EU and its Member States are discussing the design of a post-2020 policy portfolio. In a discussion paper commissioned by the European Copper Institute, Ecofys shows that an EU-wide renewable energy target is a necessary part of a 2030 portfolio. The paper analyses, in detail, two realistic policy portfolio options for renewable energy, target-setting in particular: one 'decarbonisation-only' EU target with voluntary national targets for renewable energy, and one that includes an EU-wide renewable energy target, broken down into binding national targets. The analysis shows that the latter option, when supported by appropriate and improved EU and Member States' policies and measures, is most suitable in facilitating a European low-carbon economy.

Enhanced Cooperation - the New Trend of the EU Development

Full Text Available The article is dedicated to implementation of the enhanced cooperation in the EU. Actually two such projects are шn progress (the law applicable to divorce and legal separation and unitary patent protection and other two are under discussionffmandai transaction tax and European Public Prosecutor's Office. Active use of the enhanced cooperation recently shows that such kind of the promoting integration is more and more required in the EU. However its implementation can jeopardize the principles of the EU functioning and undermine the status of the institutions in the integration process. This mechanism can also be used in order to exclude the discordant states from integration process instead of traditional search of compromises. This argument is based on analysis of the implementation conditions of the project on the unitary patent protection. At the same time the projects of the enhanced cooperation obviously make the interaction in different spheres more efficient. In addition they can be used for testing the new types of cooperation. That's why the search for an optimal balance between promotion integration through the mechanism of enhanced cooperation and preserving the unity of the EU should be considered as main goal by participants of the integration process. Otherwise the gradual separation on the vanguard group may lead to EU division. Nevertheless taking into consideration enlargement of the EU and its diversity, the enhanced cooperation Should be used onlyas "extreme measure".

The EU-Russia Energy Dialogue: Competition Versus Monopolies

Milov, V.

2006-01-01

Russia and the European Union have clearly entered a new stage in their energy relations, defined by a growing asymmetry between a strengthened national monopoly on the supply side and a gradual opening of markets in Europe. In this context, a multitude of new approaches to EU Russia energy relations have been voiced recently by a wide variety of experts. Unfortunately, many of them involve 'defensive' solutions, driven by lack of mutual trust on both sides. Is a positive approach nevertheless still possible? The paper argues that competition is a key universal value in the development of a new and sustainable energy relationship between Russia and Europe. It is clear that EU competition regulators should take the lead in setting up a new framework for EU-Russia energy relations in the future. The success of their endeavors will not only determine the security of energy supply for European consumers, but also that of the Russian and Eurasian energy markets. (author)

Enlarging the EU's internal energy market: Why would third countries accept EU rule export?

International Nuclear Information System (INIS)

Prange-Gstoehl, Heiko

2009-01-01

Why would countries without a membership perspective seek integration into the EU's internal energy market? One major element of the EU's external energy policy is the export of EU energy norms and regulations to neighbourhood countries and beyond. A core legal instrument the EU uses in this context is the Energy Community Treaty (ECT). The ECT goes both geographically and regarding its depth significantly beyond neighbourhood or association policies, addressing potentially also countries in the 'far neighbourhood' and aiming at the creation of a Single Market for energy with these countries. While, however, EU candidate countries are obliged to adopt the 'acquis' before accessing the EU and therefore comply to EU rules already before they enter the Club, I argue that countries with no or only a vague membership perspective - i.e. countries where the EU cannot apply the 'conditionality' - approach (e.g., ENP countries)-aim at deeper integration with the EU because they are either eager to demonstrate their capability and potential to become part of the Club, they seek greater independence from a regional hegemon or they envisage significant economic gains as common norms, rules and standards are likely to increase economic exchange with the EU.

2008-01-01

The EuSe nanoparticles were prepared by the thermal reduction of Europium nitrate with new organic selenium compound, tetraphenylphosphonium diphenylphosphinediselenide (PPh 4 )(Se 2 P(C 6 H 5 ) 2 ), for the first time. EuSe nanoparticles were identified by the X-ray diffraction (XRD), the transmission electron microscope (TEM) and the energy dispersive X-ray spectroscopy (EDX) measurements. The average size of the EuSe nanoparticles was found to be 19 nm. The energy gap in EuSe nanoparticles of 19 nm was estimated by edge of absorption band, giving the energy gap of 1.86 eV

Ni/EuS multilayers with excellent multilayer sequencing are deposited via e-beam evaporation on the native oxide of Si(100) wafers at 4 × 10{sup −9} millibars. The samples have very small surface and interface roughness and show sharp interfaces. Ni layers are nanocrystalline 4–8 nm thick and EuS layers are 2–4 nm thick and are either amorphous or nanocrystalline. Unlike for Co/EuS multilayers, all Eu ions are in divalent (ferromagnetic) state. We show a direct antiferromagnetic coupling between EuS and Ni layers. At room temperature, the EuS layers are spin-polarized due to the proximity of Ni. Therefore, Ni/EuS is a candidate for room-temperature spintronics applications.

Thermodynamic assessment of EuBr2 unary and LiBr-EuBr2 and NaBr-EuBr2 binary systems

International Nuclear Information System (INIS)

Gong, Weiping; Gaune-Escard, Marcelle

2009-01-01

As a basis for the design and development of molten salt mixtures, thermodynamic calculations of the phase diagrams and thermodynamic properties were carried out on the EuBr 2 unary and LiBr-EuBr 2 and NaBr-EuBr 2 binary systems over a wide temperature and composition range, respectively. The Gibbs energy of EuBr 2 was evaluated using an independent polynomial to fit the experimental heat capacity, the thermodynamic parameters for each phase in the LiBr-EuBr 2 and NaBr-EuBr 2 systems were optimized by using available experimental information on phase diagrams. A regular substitutional solution model for the liquid phase and Neumann-Kopp rule for the stoichiometric compound LiEu 2 Br 5 were adopted to reproduce the experimental data with reasonable excess Gibbs energy. Comparisons between the calculated phase diagrams and thermodynamic quantities show that all reliable experimental information is satisfactorily accounted for by the present thermodynamic description. Some thermodynamic properties were predicted to check the suitability of the present calculation.

CsI:Eu{sup 2+} needle crystal layers were produced by Physical Vapour Deposition (PVD). The luminescence properties were studied before and after thermal anneal. It was shown by Electron Paramagnetic Resonance (EPR) that annealing produces Eu{sup 2+} monomer centres, probably starting from Eu clusters in the needle crystalline layers. These centres seem structurally very similar to the Eu{sup 2+} monomer centres in annealed CsBr:Eu{sup 2+} needle layers. They give rise to a narrow luminescence band peaking at about 450 nm (2.76 eV) at room temperature, both under X-ray and UV excitation. The luminescence intensity of as-deposited layers is low. Annealing enhances photo- and radioluminescence on average by a factor of 1.5–3. Surprisingly, further sensitization of radioluminescence with a factor of up to 7 is possible by exposing the annealed needle layers to X-rays or UV, while in contrast, UV excited luminescence is slightly reduced. X-ray enhancement thus leads to a structured scintillator with a conversion efficiency of about 42,000 photons/MeV upon X-ray excitation. A similar radioluminescence enhancement is observed for annealed CsI:Eu{sup 2+} fine powder, but not for large single crystals or conglomerated polycrystals. The measurements and observations are consistent with Eu{sup 2+} monomer centres stabilized by water molecules. These molecules are incorporated via annealing, and that this happens when the morphology is such that water can diffuse throughout the volume of the crystals. The presence of stabilized Eu{sup 2+} monomers is necessary to enhance radioluminescence by X-ray exposure. A mechanism is proposed for the phenomenon.

Torisky, R S; Griffin, J D; Yenofsky, R L; Polacco, J C

1994-02-01

We sought to determine the genetic basis of expression of the ubiquitous (metabolic) urease of soybean. This isozyme is termed the metabolic urease because its loss, in eu4/eu4 mutants, leads to accumulation of urea, whereas loss of the embryo-specific urease isozyme does not. The eu4 lesion eliminated the expression of the ubiquitous urease in vegetative and embryonic tissues. RFLP analysis placed urease clone LC4 near, or within, the Eu4 locus. Sequence comparison of urease proteins (ubiquitous and embryo-specific) and clones (LC4 and LS1) indicated that LC4 and LS1 encode ubiquitous and embryo-specific ureases, respectively. That LC4 is transcribed into poly(A)+ RNA in all tissues was indicated by the amplification of its transcript by an LC4-specific PCR primer. (The LS1-specific primer, on the other hand, amplified poly(A)+ RNA only from developing embryos expressing the embryo-specific urease.) These observations are consistent with Eu4 being the ubiquitous urease structural gene contained in the LC4 clone. In agreement with this notion, the mutant phenotype of eu4/eu4 callus was partially corrected by the LC4 urease gene introduced by particle bombardment.

We look at migration flows from 8 Central and Eastern European Countries (CEECs) to 5 Nordic countries over the years 1985 - 2005 and we can exploit a natural experiment that arose from the fact that while Sweden opened its labour market from the day one of the 2004 EU enlargement, the other Nordic...... countries chose a transition period in relation to the "new" EU members. We employ a differences-in-differences estimator in our analysis. The results show that the estimated effect of the opening of Swedish labour market in 2004 on migration is insignificantly different from zero.

Therefore we look at migration flows from CEECs during the first round EU enlargement towards CEECs in 2004 and compare them with migration flows from Bulgaria and Romania.

2014-12-01

Full Text Available National governments are keenly aware of the need for investment in space. Canada, as a formal cooperating state in the European Space Agency (ESA, and Germany, as a leading member state of ESA, are interlinked in Europe’s space endeavours. Beyond ESA, Germany and Canada additionally have a strong history of bilateral cooperation on a range of space projects. This paper discusses the novel interdependencies between clear national and now supranational space policies, using the examples of the Canada-European Union (EU Comprehensive Economic and Trade Agreement (CETA. The agreement covers most aspects of the EU-Canada bilateral economic relationship and includes space. The paper focuses on international space policies, strategic bilateral co-operation, and technical accomplishments. It takes a closer look at German-Canadian collaboration in space programs and offers some reflection on the effect of both the EU and ESA’S transatlantic involvement in space.

The IFIEC method for the allocation of CO2 allowances in the EU Emissions Trading Scheme. A review applied to the electricity sector

2008-03-01

Recently the European Commission has published a proposal to improve the function of the EU-ETS by amending the Directive which establishes the EU-ETS. The main changes proposed are the establishment of one EU-wide cap and the use of auctioning for a much greater share of allowances than is currently the case, replacing most of the allocation free of charge. Auctioning of allowances will eliminate the so-called windfall profits that occur under the current allocation free of charge that is based on historic production and emission levels; a grandfathering approach. IFIEC EUROPE, the international federation of industrial energy consumers, asked Ecofys to review the method that IFIEC has developed in recent years to allocate CO2 allowances in the EU emissions trading scheme (EU-ETS). According to IFIEC, their allocation method guarantees the same environmental outcome as other methods, without causing windfall profits and with lower risks of competitiveness loss for so-called exposed industrial users of electricity. It was decided to focus this study on the European electricity sector. This was done for several reasons: CO2 emissions from electricity generation cover a large part of the overall emission under EU-ETS, the electricity sector has a single well defined output (electricity) that can be used to illustrate the potential impact of the IFIEC benchmark based allocation approach, and electricity is a substantial cost factor for IFIEC members. This evaluation covers many aspects of IFIEC's method and compares these with two other allocation methods: auctioning and historic grandfathering. Within the IFIEC method two example approaches are evaluated: a single benchmark for electricity production and fuel-specific benchmarks for coal and gas fired electricity production. In the evaluation, we cover the following aspects: What is the IFIEC method; how does it differ from other allocation methods in character (chapter 2); What is the impact of different allocation

A cost–benefit analysis of the EU 20/20/2020 package

International Nuclear Information System (INIS)

Tol, Richard S.J.

2012-01-01

The European Commission did not publish a cost–benefit analysis for its 2020 climate package. This paper fills that gap, comparing the marginal costs and benefits of greenhouse gas emission reduction. The uncertainty about the marginal costs of climate change is large and skewed, and estimates partly reflect ethical choices (e.g., the discount rate). The 2010 carbon price in the EU Emissions Trading System can readily be justified by a cost–benefit analysis. Emission reduction is not expensive provided that policy is well-designed, a condition not met by planned EU policy. It is probably twice as expensive as needed, costing one in ten years of economic growth. The EU targets for 2020 are unlikely to meet the benefit–cost test. For a standard discount rate (3% pure rate of time preference), the benefit–cost ratio is rather poor (1/30)—so that benefits need to be very much higher, or costs very much lower than typically assumed to justify the 2020 targets. Only a very low discount rate (0% PRTP) would justify the 20% emission reduction target for 2020. - Highlights: ► First cost–benefit analysis of EU climate policy for 2020. ► Current carbon price in ETS can readily be justified by CBA. ► Emission targets for 2020 cannot be supported unless a low discount rate is chosen.

The emitting color varies from blue to green with increasing of Eu 2+ content for the Eu 2+ -doped phosphor, and the quantum yield of the 0.05Eu 2+ : Ca 2.95 (PO 4 ) 2 sample reaches 56.7%. Interestingly, Mn 2+ co-doping into Eu 2+ : Ca 3 (PO 4 ) 2 leads to its phase transition from orthorhombic to rhombohedral, and subsequently generates tunable multi-color luminescence from green to red via Eu 2+ → Mn 2+ energy transfer. - Highlights: • A series of novel Eu 2+ : Ca 3 (PO 4 ) 2 phosphors were successfully synthesized. • Phase transition of Ca 3 (PO 4 ) 2 from orthorhombic to rhombohedral occurred when Mn 2+ ions were doped. • The phosphors exhibited tunable multi-color luminescence. • The quantum yield of 0.05Eu 2+ : Ca 2.95 (PO 4 ) 2 phosphor can reach 56.7%. • The analyses of phosphors were carried out by many measurements. - Abstract: Intense blue-green-emitting Eu 2+ : Ca 3 (PO 4 ) 2 and tunable multicolor-emitting Eu 2+ /Mn 2+ : Ca 3 (PO 4 ) 2 phosphors are prepared via a solid-state reaction route. Eu 2+ -doped orthorhombic Ca 3 (PO 4 ) 2 phosphor exhibits a broad emission band in the wavelength range of 400–700 nm with a maximum quantum yield of 56.7%, and the emission peak red-shifts gradually from 479 to 520 nm with increase of Eu 2+ doping content. Broad excitation spectrum (250–420 nm) of Eu 2+ : Ca 3 (PO 4 ) 2 matches well with the near-ultraviolet LED chip, indicating its potential applications as tri-color phosphors in white LEDs. Interestingly, Mn 2+ co-doping into Eu 2+ : Ca 3 (PO 4 ) 2 leads to its phase transition from orthorhombic to rhombohedral, and subsequently generates tunable multi-color luminescence from green to red via Eu 2+ → Mn 2+ energy transfer, under 365 nm UV lamp excitation

Electricity generation in the European Union (EU) decreased by 0,7% in the period of 2001 to 2002, reaching 2521,3 billion kWh. Developments varied in different countries. Conventional thermal power plants generated 1340,1 billion kWh, which corresponds to a 53.0% share in the total generation and an increase by 2.7% over the level in the previous year. Generation in nuclear power plants increased by 2.7% to 855.5 billion kWh, which corresponds to a 33,8% share in EU-wide generation. Hydroelectric plants and other plants supplied 15.2% less electricity. Eurostat statistics do not differentiate these data any further. The volume of 332.2 kWh is tantamount to a 13.1% share. In the new EU member countries and the candidate countries, electricity generation showed a moderate increase by 0.4% and 2.1%, respectively. While generation both in conventional power plants and in other plants decreased, a considerable increase is shown for nuclear power generation of +13.5% and +10.6%, respectively [de

Ligand L, based on two do3a moieties linked by the methylene groups of 6,6'-dimethyl-2,2'-bipyridine, was synthesized and characterized. The addition of Ln salts to an aqueous solution of L (0.01 M Tris-HCl, pH 7.4) led to the successive formation of [LnL] and [Ln(2)L] complexes, as evidenced by UV/Vis and fluorescence titration experiments. Homodinuclear [Ln(2)L] complexes (Ln = Eu, Gd, Tb, Yb, and Lu) were prepared and characterized. The (1)H and (13)C NMR spectra of the Lu and Yb complexes in D(2)O solution (pD = 7.0) showed C(1) symmetry of these species in solution, pointing to two different chemical environments for the two lanthanide cations. The analysis of the chemical shifts of the Yb complex indicated that the two coordination sites present square antiprismatic (SAP) coordination environments around the metal ions. The spectroscopic properties of the [Tb(2)L] complex upon ligand excitation revealed conventional behavior with τ(H2O) = 2.05(1) ms and ϕ(H2O) = 51%, except for the calculation of the hydration number obtained from the luminescent lifetimes in H(2)O and D(2)O, which pointed to a non-integer value of 0.6 water molecules per Tb(III) ion. In contrast, the Eu complex revealed surprising features such as: 1) the presence of two and up to five components in the (5)D(0)→(7)F(0) and (5)D(0)→(7)F(1) emission bands, respectively; 2) marked differences between the normalized spectra obtained in H(2)O and D(2)O solutions; and 3) unconventional temporal evolution of the luminescence intensity at certain wavelengths, the intensity profile first displaying a rising step before the occurrence of the expected decay. Additional spectroscopic experiments performed on [Gd(2-x)Eu(x)L] complexes (x = 0.1 and 1.9) confirmed the presence of two distinct Eu sites with hydration numbers of 0 (site I) and 2 (site II), and showed that the unconventional temporal evolution of the emission intensity is the result of an unprecedented intramolecular Eu-to-Eu

Tuning of "antenna effect" of Eu(III) in ternary systems in aqueous medium through binding with protein.

A simple ternary system containing a protein [human serum albumin (HSA)/bovine serum albumin (BSA)], tetracycline hydrochloride (TC), and Eu(III) in suitable aqueous buffer medium at physiological pH (= 7.2) has been shown to exhibit highly efficient "antenna effect" compared to the binary complex of TC with Eu(III) (Eu(3)TC). The ternary system containing E. coli alkaline phosphatase (AP), TC, and Eu(III), however, shows a slight enhancement of Eu(III) emission, although the binding constant of AP with TC is 2 orders of magnitude greater than with BSA/HSA. The enhanced emission of bound TC in the binary systems containing proteins and TC gets quenched in the ternary systems containing HSA/BSA, showing the efficient energy transfer (ET) from TC to Eu(III). Steady state and time-resolved emission studies of each component in all the ternary systems in H(2)O and in D(2)O medium reveal that Eu(III) is very well protected from the O-H oscillator in the ternary system containing HSA/BSA compared to that containing AP. The docking studies locating the binding site of TC in the proteins suggest that TC binds near the surface of AP. In the case of HSA/BSA, TC resides in the interior of the protein resulting in a large shielding effect of Eu(III). The rotational correlation time (θ(c)) determined from the anisotropy decay of bound TC in the complexes and the accessible surface area (ASA) of the ligand in the complexes obtained from the docking studies also support the contention that Eu(3)TC is more exposed to solvent in the case of the ternary system consisting of AP, TC, and Eu(III). The calculated radiative lifetime and the sensitization efficiency ratio of Eu(III) in all the systems clearly demonstrate the protein mediated tuning of "antenna effect" in Eu(III).

The EU 2030 Climate and Energy Framework presents a number of technical challenges whose solution will be essential to its effectiveness. These include: the question of the role and reform of the ETS, the approach to decarbonization of non-ETS sectors, and the mechanisms that exist for governing the package of policies at EU and Member State level. This discussion paper presents preliminary results from an analysis of these challenges, as well as proposals that could be included in the package of post- 2020 climate policies. (authors)

A work-life balance is one of the factors that increases an employee's individual satisfaction, leading to higher economic performance, an aspect that is found in most EU strategic documents dealing with the labour market. Focusing on gender differences, the article carries out a comparative analysis of the situation in EU Member States, on several dimensions: working time, flexible work arrangements, providing opportunities for assuming different domestic responsibilities etc.

Challenges of public procurement in EU funded projects

Directory of Open Access Journals (Sweden)

Marko Šostar

2017-01-01

Full Text Available Membership in the European Union implies adjustment of EU projects to the rules of Structural Funds, but also adoption of legal regulations, thus influencing the process of implementation of the public procurement in EU funded projects. Each successful applicant who expressed the need for procurement of goods, services and works of a certain value, must respect the principles of public procurement. Irregularities in the procurement process can lead to the failure of returning the EU funds even several years after the end of the project. Therefore, the knowledge and proper implementation of public procurement is the main precondition for the correct implementation of each project. In order to obtain information about the current absorption capacity of the public procurement liable parties, and to identify key obstacles that stakeholders face in procurement procedures, the research was conducted by surveying 30 entities that are subject of public procurement in Croatia. Research results imply the poor quality of public procurement in the implemented projects, which often results in financial corrections, disapproving project reports, etc.

EU environmental policy and competitiveness

Directory of Open Access Journals (Sweden)

Stojanović Boban

2006-01-01

Full Text Available Protection of the environment was not a specific importance to the Community although the Treaty of Rome expressly specified that "health, safety environmental protection" shall be based on "a high level of protection". In deciding upon a framework for a European environmental policy, the Community was also responding to increased public awareness of the problem and concerns about the state of the natural and man-made environment. During the past years, competitiveness concerns have dominated the EU policy debate, in the course of which a growing consensus is being developed on the importance of eco-innovations and resource efficiency for EU competitiveness and on the market opportunities they offer. There is an increasing evidence that environmental policy and eco-innovations can promote economic growth, as well as maintain and create jobs, contributing both to competitiveness and employment. Environmental constraints to rapid economic growth are increasingly recognized by countries, leading to a rising awareness of the need for sustainable development. Implementation of an environmental policy however, generates significant implications for competition among countries.

EU-Russia Cultural Relations

Directory of Open Access Journals (Sweden)

Elena Sidorova

2014-05-01

Full Text Available This article analyzes the link between culture and diplomacy between Russia and the European Union, and shows the importance of cultural relations. It examines the common space of science, education and culture introduced at the 2003 EU-Russia Summit in St. Petersburg and the application of the principles of this concept that were established at the 2005 EU-Russia Summit in Moscow. It then considers EU-Russia collaboration on humanitarian action and the challenges that both parties face in this sphere. It also explains the formation of EU domestic and foreign cultural policy, and the role of European institutions and states in cultural affairs and diplomacy, as well as key elements and mechanisms of contemporary Russian foreign cultural policy. In addition, the article focuses on the European side of post-Soviet EU-Russia cultural relations. This cultural collaboration is defined as a competitive neighbourhood. EU and Russian interests collide: while Europeans try to promote their values, norms and standards within the framework of the European Neighbourhood Policy, Russia seeks to culturally influence and engage in this region for geostrategic and historical reasons. Finally, the article assesses the prospects for the EU-Russia cultural relations and emphasizes the role of ideology in improving such relations.

Consistency of policy instruments. How the EU could move to a -30% greenhouse gas reduction target

Energy Technology Data Exchange (ETDEWEB)

Hoehne, N.; Hagemann, M.; Moltmann, S.; Escalante, D. [Ecofys Germany, Berlin (Germany)

2011-04-15

The report provides options for how to achieve a 30% reduction in greenhouse gas emissions, in the EU, from 1990 to 2020. The EU has agreed a set of goals (objectives) and related instruments for 2020. The most significant objectives are the 20% or 30% reduction of greenhouse gases (all emissions, both within and outside the Emissions Trading System), the 20% improvement of energy efficiency and the 20% of renewable energy use by 2020. The stringency of the instruments used to reach these goals, must be set carefully to ensure overall consistency. Particularly after the economic crisis of 2008/2009, the Climate and Energy Package has to be 'tuned' again to be fully consistent, e.g. fast take up of renewable energy and fewer emissions due to the recession may cause an over-allocation in the EU-ETS.

Gd{sup 3+} and Eu{sup 3+} ions co-doped CaCO{sub 3} nanoparticles have been successfully synthesized via carbonization method. The emission spectra of co-doped CaCO{sub 3} phosphors in the range of VUV–vis spectral were studied. The results reveal that the co-doped CaCO{sub 3} phosphors show intense red emission in the VUV range because of the Gd{sup 3+} ions as sensitizers. The energy transfer process from Gd{sup 3+} to Eu{sup 3+} in CaCO{sub 3}:Gd{sup 3+}/Eu{sup 3+} phosphors was investigated and discussed in terms of the luminescence spectra and the decay curves, which demonstrated that the energy transfer of Gd{sup 3+}→Eu{sup 3+} is efficient. The mechanism of energy transfer from Gd{sup 3+} to Eu{sup 3+} is a resonant transfer, in which electric dipole–dipole interaction plays a leading role. Furthermore, the effect of doping concentration of Eu{sup 3+} ions on the energy transfer efficiency was also investigated. From the photoluminescence (PL) spectra, it was also found that the incorporation of Na{sup +} ions into CaCO{sub 3}:Gd{sup 3+}/Eu{sup 3+} could lead to a remarkable increase of luminescent intensity due to the charge compensation.

BaCl 2 :Eu 2+ microcrystals embedded in the NaCl host have been obtained in the NaCl–BaCl 2 (1 mol%)–EuCl 3 (0.02 mol%) crystalline system. The influence of the annealing conditions on the formation of such particles has been studied. In particular, long-term annealing (at 200 °S during 100 h) promotes the microcrystals formation in the NaCl–BaCl 2 –Eu crystalline system. The subsequent heat treatment (annealed at 600 °S during 72 h and quenched to room temperature) is shown to lead to the destruction of the majority of these particles. The luminescent-kinetic properties of BaCl 2 :Eu 2+ microcrystals have been studied upon the ultra-violet excitation by the synchrotron radiation. The X-ray excited luminescence has been measured in order to estimate the distribution of europium ions between microcrystals and the NaCl host. The excitation mechanisms of Eu 2+ ions in the NaCl–BaCl 2 –Eu crystalline system are discussed. - Highlights: ► The formation of BaCl 2 :Eu 2+ microcrystals of 1–100 μm size embedded in the NaCl host is revealed. ► Annealing at 600 °C leads to the destruction of significant number of embedded microcrystals. ► The luminescent parameters of microcrystals is similar to ones of single crystal analogs.

Argentinean propolis is exported to different countries, specially Japan. The market demands propolis quality control according to international standards. The analytical determination of some metals, as lead in food, is very important for their high toxicity even in low concentrations and because of their harmful effects on health. Flavonoids, the main bioactive compounds of propolis, tend to chelate metals as lead, which becomes one of the main polluting agents of propolis. The lead found in propolis may come from the atmosphere or it may be incorporated in the harvest, extraction and processing methods. The aim of this work is to evaluate lead level on Argentinean propolis determined by electrothermal atomic absorption spectrometry (ET AAS) and UV-vis spectrophotometry (UV-visS) methods, as well as the effect of harvest methods on those contents. A randomized test with three different treatments of collection was made to evaluate the effect of harvest methods. These procedures were: separating wedges (traditional), netting plastic meshes and stamping out plastic meshes. By means of the analysis of variance technique for multiple comparisons (ANOVA) it was possible to conclude that there are significant differences between scraped and mesh methods (stamped out and mosquito netting meshes). The results obtained in the present test would allow us to conclude that mesh methods are more advisable than scraped ones in order to obtain innocuous and safe propolis with minor lead contents. A statistical comparison of lead determination by both, ET AAS and UV-visS methods, demonstrated that there is not a significant difference in the results achieved with the two analytical techniques employed.

Thin films of Eu 2+ /Er 3+ codoped barium strontium silicate were deposited on a thermal oxide Si substrate by magnetron sputtering. Optical properties suggest that after a rapid annealing process, these films can lead to efficient Er 3+ emission at 1.54 μm with a lifetime of about 7.9 ms. Intense 1.54-μm light emission was achieved under broad ultraviolet light excitation through efficient energy transfer from Eu 2+ to Er 3+ . These results indicate that the Eu 2+ /Er 3+ thin films have potential applications as low cost and compact erbium doped waveguide amplifiers pumped by LEDs. - Highlights: • The Er 0.07 Eu 0.14 Sr 1.14 Ba 0.79 SiO 4 films are fabricated by magnetron sputtering. • Efficient energy transfer from Eu 2+ to Er 3+ ions by the dipole–dipole interaction. • Intense 1.54 μm emission is achieved under broad excitation spectrum. • The films have potential applications as low cost and compact EDWAs

The purpose of this paper is the measurement of the relative intensities of the most intensive conversion lines of 152 Eu, the determination of as reliable as possible magnitudes of the intensities of γ-quanta using all the available data on γ-radiation of 152 Eu, the measurement of the interval conversion coefficients (ICC) for the most intensive γ-transitions, the determination of the probabilities of the 152 Eu β-decays to the 152 Sm and 152 Gd levels. The conversion lines of the most intensive γ-transitions in the 152 Eu decay are studied and the corresponding ICC are measured on the beta-spectrometers of π√2 and UMB type. The balance for the γ-transitions in the 152 Sm and 152 Gd daughter nuclei are presented. This balance is used to determine the absolute intensities of γ-rays (in terms of the percentage of the 152 Eu decays) and the probabilities of β-transitions to the levels of daughter nuclei. More accurate data on γ-rays and conversion electrons obtained can be used for the calibration of gamma and beta spectrometers

High-Precision Measurement of Eu/Eu* in Geological Glasses via LA-ICP-MS Analysis

Tang, Ming; McDonough, William F.; Arevalo, Ricardo, Jr.

Elemental fractionation during laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) analysis has been historically documented between refractory and volatile elements. In this work, however, we observed fractionation between light rare earth elements (LREEs) and heavy rare earth elements (HREEs) when using ablation strategies involving large spot sizes (greater than 100 millimeters) and line scanning mode. In addition: (1) ion yields decrease when using spot sizes above 100 millimeters; (2) (Eu/Eu*)(sub raw) (i.e. Europium anomaly) positively correlates with carrier gas (He) flow rate, which provides control over the particle size distribution of the aerosol reaching the ICP; (3) (Eu/Eu*)(sub raw) shows a positive correlation with spot size, and (4) the changes in REE signal intensity, induced by the He flow rate change, roughly correlate with REE condensation temperatures. The REE fractionation is likely driven by the slight but significant difference in their condensation temperatures. Large particles may not be completely dissociated in the ICP and result in preferential evaporation of the less refractory LREEs and thus non-stoichiometric particle-ion conversion. This mechanism may also be responsible for Sm-Eu-Gd fractionation as Eu is less refractory than Sm and Gd. The extent of fractionation depends upon the particle size distribution of the aerosol, which in turn is influenced by the laser parameters and matrix. Ablation pits and lines defined by low aspect ratios produce a higher proportion of large particles than high aspect ratio ablation, as confirmed by measurements of particle size distribution in the laser induced aerosol. Therefore, low aspect ratio ablation introduces particles that cannot be decomposed and/or atomized by the ICP and thus results in exacerbated elemental fractionation. Accurate quantification of REE concentrations and Eu/Eu* requires reduction of large particle production during laser ablation. For the reference

Pourquoi Hume et Kant ont eu tort de rejeter la théologie naturelle

Directory of Open Access Journals (Sweden)

2012-07-01

Full Text Available La théologie naturelle faisait partie de la tradition philosophique occidentale jusqu’à ce que Hume et Kant affirment qu’il y a des limites fondamentales à l’intelligibilité, ou au moins au savoir possible, de ce qui dépasse l’expérience ; et donc qu’il ne peut exister d’arguments solides partant du monde naturel et concluant à l’existence de Dieu. Je défends que, bien que nos concepts doivent en effet être dérivés de notre expérience, ils peuvent avoir une application bien au-delà de notre expérience ; et que la science moderne nous a montré comment des théories à propos de choses au-delà de notre expérience pouvaient être rendues probables par les données de l’expérience. Un point important dans les arguments de Hume et de Kant est que le concept de ‘cause’ n’a d’application que pour les successions régulières d’événements observables. J’argumente contre eux en montrant que, puisque nous dérivons originairement ce concept de notre propre expérience quand nous sommes cause d’événements, son application n’est en aucun cas limitée aux successions régulières d’événements observables. J’en conclus que les arguments de Hume et Kant n’ont pas du tout de force pour montrer l’impossibilité d’une théologie naturelle solide.

Regulatory landscape for cell therapy--EU view.

Science.gov (United States)

McBlane, James W

2015-09-01

This article addresses regulation of cell therapies in the European Union (EU), covering cell sourcing and applications for clinical trials and marketing authorisation applications. Regulatory oversight of cell sourcing and review of applications for clinical trials with cell therapies are handled at national level, that is, separately with each country making its own decisions. For clinical trials, this can lead to different decisions in different countries for the same trial. A regulation is soon to come into force that will address this and introduce a more efficient clinical trial application process. However, at the marketing authorisation stage, the process is pan-national: the Committee for Human Medicinal Products (CHMP) is responsible for giving the final scientific opinion on all EU marketing authorisation applications for cell therapies: favourable scientific opinions are passed to the European Commission (EC) for further consultation and, if successful, grant of a marketing authorisation valid in all 28 EU countries. In its review of applications for marketing authorisations (MAAs) for cell therapies, the CHMP is obliged to consult the Committee for Advanced Therapies (CAT), who conduct detailed scientific assessments of these applications, with assessment by staff from national regulatory authorities and specialist advisors to the regulators.

Modelling the impacts of challenging 2020 non-ETS GHG emissions reduction targets on Ireland′s energy system

International Nuclear Information System (INIS)

Chiodi, Alessandro; Gargiulo, Maurizio; Deane, J.P.; Lavigne, Denis; Rout, Ullash K.; Ó Gallachóir, Brian P.

2013-01-01

This paper focuses on Ireland's ambitious target for 2020 to reduce greenhouse gas (GHG) emissions by 20% below 2005 levels for sectors not covered by ETS (Non-ETS). Ireland is an interesting case study due to the role of agriculture (a particularly challenging sector with regard to GHG emissions reduction), that represents 29% of Ireland's GHG emissions compared with less than 10% for the EU. The analysis is carried out with the Irish TIMES model, a bottom-up energy systems modelling tool with detailed characterization of Ireland's energy system. The paper uses scenario analysis to provide pathways that demonstrate how Ireland can meet the non-ETS target at least cost. The paper considers the impacts (in terms of different technology choices and higher marginal abatement costs) arising from higher targets for the energy system to compensate for growth in agriculture activity and low mitigation potential in that sector. The results point to a need to reconsider Ireland's renewable energy focus, with a need for increased effort in renewable transport and renewable heat in particular. The results also point to significant electrification of residential heating. The results also point to a high marginal abatement cost (€213/tCO 2 ), which challenges the analysis carried out at EU level to establish Ireland's non-ETS target. - Highlights: • Techno-economic energy model to deliver EU GHG mitigation target by 2020 in Ireland. • Agriculture represents nearly half of Non-ETS emissions in Ireland. • The target set for Non-ETS GHG for Ireland is far from a cost optimal target. • The results point to a need to reconsider Ireland's renewable energy focus. • Key pathways: electrification of heating in buildings and biofuels in transport

Financial effects of ETS Set Aside

Energy Technology Data Exchange (ETDEWEB)

Van Dril, T. [ECN Policy Studies, Petten (Netherlands)

2012-11-26

The EU ETS (emissions trading system) has a growing surplus of allowances built up over the last few years. The economic downturn is regarded to be a major cause of the oversupply and the low level of the CO2 allowance price. From 2013 onwards, the ETS will enter its third phase in which a substantial part of the current allowances will be auctioned. In summer 2012, the European Commission proposed a draft Regulation to adjust the timing of auctions of emission allowances. The Commission states that it is not wise to feed a market that is already oversupplied and wants to auction fewer allowances in the next years (Set Aside). These Set Aside allowances should then be auctioned in the later years of the 2013-2020 ETS period (backloading). The proposal document does not suggest permanent withdrawal of allowances, since this requires amending the ETS directive. However, permanent withdrawal (cancellation) is certainly considered as an option to reinforce the ETS. The Netherlands Ministry of Finance is primarily interested in the economic effects of Set Aside scenarios. This paper focuses on the effects of Set Aside allowances on the government budget. Not just the auction revenues are considered, but also the indirect effect on funding renewable energy generation.

EU Foreign Energy Policy. From Intergovernmentalism to Supranationalism

International Nuclear Information System (INIS)

Ahner, N.

2012-01-01

The European Union's increasing reliance on imports from third countries is reason for unsettling concern. It is anticipated that by 2030, assuming a continuation of the recent trend, more than 70 per cent of the EU's energy consumption has to be imported. Notwithstanding such anticipation, European regulation addressing the external dimension of energy policy remained far and few between. In practise it is the individual countries being leading actors on the foreign energy relations stage exercising their own respective foreign policies. To cope with these threats to the EU foreign energy policy, the European Commission issued its long anticipated Communication on security of energy supply and international cooperation proposing concrete instruments on how energy foreign relations should be addressed in the future. But - does the Union have the power to bring about the crucial rebound?.

The study evaluates the impacts of EU climate policy on the emission allowance price, electricity prices, the competitiveness of industry and macroeconomic developments in the third EU emission trading period 2013-2020. The economic impacts of climate policy on Finland are compared to the impacts on the entire EU area. It turns out that due to its cold climate and heating energy demand, higher export intensity of the economy and higher energy intensity of the industry Finland pays a higher price for EU climate policy in terms of output and employment losses than the EU on average. The study examines the macroeconomic effects of climate policy also in the more distant future, assuming that climate policy is tightened further in the 2020s. Climate policy implemented by emission trading means that the long-term economic growth in the EU area depends essentially on emission-free electricity production, and no longer on other growth factors, such as the labour supply and productivity growth.

Yttrium aluminium garnet (YAG) doped with Eu 2+ and Eu 3+ ions is very interesting as a phosphor for conversion of light-emitting diode light for white light sources. The europium ion occupies the structural position of yttrium in yttrium aluminium garnet and has valence state Eu 3+ . Our sample was doped with Zr 4+ , which is why some of the europium ions had valence state Eu 2+ . As a rule, luminescence of Eu 3+ ions is observed in the orange and red range of spectrum. The luminescence of Eu 2+ in yttrium aluminum garnet is characterized by an intensive broad band with maximum of intensity at about 560 nm (green color). In this work, we studied the intensity and decay time dependences on europium concentration, and the influence of excitation power density on the cathodoluminescence of the sample. The most interesting result is the change of visible cathodoluminescence color in dependence on the density of the exciting power

Negative pressure driven valence instability of Eu in cubic Eu0.4La0.6Pd3

International Nuclear Information System (INIS)

Pandey, Abhishek; Mazumdar, Chandan; Ranganathan, R

2009-01-01

We report the change in the valency of Eu-ions in the binary intermetallic cubic compound EuPd 3 induced by La doping at rare-earth sites. Doping of La generates negative chemical pressure in the lattice, resulting in a significant increase of the lattice parameter without altering the simple-cubic structure of the compound. Results of dc-magnetic measurements suggest that this increase in the lattice parameter is associated with the valence transition of Eu-ions from Eu 3+ to a mixed-valent state. As Eu 2+ -ions possess a large magnetic moment, this valence transition significantly modifies the magnetic behavior of the compound. In contrast to introducing boron at the vacant body center site of the unit cell to change the valency of Eu-ions, as in the case of EuPd 3 B, our results suggest it can also be altered by doping a rare-earth ion of larger size at the lattice site of Eu in EuPd 3 .

Influence of hydroxybenzoic acids on the adsorption of Eu(III) onto α,γ-Al_2O_3 particles in mildly acidic conditions: A macroscopic and spectroscopic study

The influence of hydroxybenzoic acids (HAH_n), namely p-hydroxybenzoic acid (4-hydroxybenzoic acid, HPhbH) and protocatechuic acid (3,4-dihydroxybenzoic acid, HProtoH_2), on the adsorption of europium(III) onto α,γ-Al_2O_3 particles is studied as a function of acid concentration. After measuring the adsorption edge of the Eu(III)/α,γ-Al_2O_3 binary system, and using the previously studied binary component system Eu(III)/HAH_n—Moreau et al. (2015) Inorg. Chim. Acta432, 81—, and HAH_n/α,γ-Al_2O_3—Moreau et al. (2013) Colloids Surf. A435, 97—, it is evidenced that HPhbH does not enhance Eu(III) adsorption onto α,γ-Al_2O_3 in the Eu(III)/HPhbH/α,γ-Al_2O_3 ternary system. Conversely, HProtoH_2 enhances Eu(III) adsorption onto α,γ-Al_2O_3 in the Eu(III)/HProtoH_2/α,γ-Al_2O_3 ternary system. Adsorption of the acids are also found higher in the Eu(III)/acid/α,γ-Al_2O_3 ternary systems as compared with the corresponding binary systems assessing synergetic effects. For high HPhbH concentrations, a ternary surface species involving ≡AlOH surface sites, Eu(III), and PhbH"– is evidenced by time-resolved luminescence spectroscopy (TRLS). However, in the Eu(III)/HProtoH_2/α,γ-Al_2O_3 ternary system, chemical environment of Eu(III) is found to be very close to that in the Eu(III)/HProtoH_2 binary system. Ternary surface species could not be evidenced in the Eu(III)/HProtoH_2/α,γ-Al_2O_3 ternary system with TRLS because of the very short decay time of Eu(III) in the presence of protocatechuic acid. - Highlights: • Adsorption in the Eu(III) – hydroxybenzoic acid – alumina system is studied. • Adsorption is quantified and luminescence parameters are obtained independently. • Synergistic effect of organic acids adsorption are evidenced in the ternary systems. • A ternary species is clearly shown for the p-hydrobenzoic acid.

A liquid Eu precursor, bis(normal-propyl-tetramethylcyclopentadienyl)europium has been synthesized. This precursor exists as a liquid at temperatures higher than 49 °C, has a moderately high vapor pressure, contains no oxygen in its molecular structure, and can be distilled to high purity. These properties make it ideal for doping using a chemical vapor or atomic layer deposition method, and provide a degree of control previously unavailable. As a precursor the Eu exists in the divalent valance state, however, once doped into GaN by organometallic vapor phase epitaxy, the room-temperature photoluminescence of the Eu-doped GaN exhibited the typical red emission due to the intra-4f shell transition of trivalent Eu. After variation of the growth temperature, it was found that divalent Eu could be stabilized in the GaN matrix. By tuning the Fermi level through donor doping, the ratio of Eu 2+ to Eu 3+ could be controlled. The change in valence state of the Eu ions was confirmed using X-ray absorption near-edge structure. - Highlights: • A liquid Eu precursor was synthesized and its properties were characterized. • Precursor has a low melting point and a moderately high vapor pressure. • Does not contain oxygen in its molecular structure. • Eu can changed its valance state when incorporated into GaN. • Valence state of Eu in GaN can be controlled by donor doping.

Differences and similarities between the EU and non-EU citizens

Directory of Open Access Journals (Sweden)

Iris Dhamo

2017-03-01

Full Text Available Initially, the European Union had a purely economic connotation, as his intent was the free movement of factors of production, in order to create a competitive internal market and achieving a rational distribution of resources. For this reason, the individual was seen simply as a worker and for this purpose the first aspects that are disciplined within the EU are those contained in this sphere. In the Treaty of Rome, which established the European Economic Community (EEC, the freedom of free movement was reserved for only a few special categories of workers, who were active subjects economically, since what resulted essential at the time was the creation of an internal market. Later the Maastricht Treaty, on one side marks the transition from the EEC to the EU, on the other presents for the first time the "European citizenship", making the free movement an autonomous right of every citizen belonging to a Member State. In this way the free movement is exercised not only for the economic purposes of the Treaties. In December 2000 the Charter of Fundamental Rights or the Charter of Nice was compiled and signed, which defines that the EU seeks to promote a balanced development and ensures free movement of persons, goods, services and capital, and also the freedom of residence. Main objective of this manuscript is an analysis of the differences and similarities between the EU and non-EU citizens.

PAUL BOGDAN ZAMFIR

2017-02-01

Full Text Available In this paper, the author intends to highlight the overall evolution of Romania's bilateral trade relations with EU in the period 2007-2015. On this background it is important to mention that the European Union (EU has been the main trade partner of Romania both the export and import throughout this period of post-accession. So, during the analyzed period, as can be observed from statistical data provided by INSSE it is obvious a general tendency of enhancing Romania's trade with EU. Furthermore, since 2007 EU has held a share of over 70% in total imports and exports of Romania. Also, relative to the evolution of Romania's trade balance in relation with EU, from statistical data presented in the paper, can be noticed that in the reference period it has known a general negative trend. There are also presented some positive progress of our country in issue of adjusting the trade balance deficit with EU. In these circumstances, can be proposed a range of macroeconomic measures formulated in direction of reducing the trade deficit, registered by our country in relation with EU. Another element of maximum visibility in this analyzed issues is represented by geographical orientation of Romanian exports and imports with EU countries. Starting from statistical data provided by INSSE through the prestigious official publication Romanian International Trade Yearbook, results clearly that in the whole of this reference period, Germany had the most significant share of over 20%, both export and import. Also during this period of post-accession, the attention of policy makers should focus on measures that will can lead to increase of Romania 's trade not only with Germany, Italy, France, Hungary etc. but also with other community partners whose share in Romania's total trade with EU was a insignificant along analysed period. Thus, in the current context and in perspective for Romania is imperative necessary the proliferation, intensification and

2013-01-01

Full Text Available The discussion about the possible taxation of the financial sector has started in the European Union as a result of the financial crisis which has spread to the Europe from the United States in 2008. European Commission concluded that EU should lead the efforts to introduce system of levies or taxies on financial institutions. EU member states individually committed to support the financial sector for a total about EUR 4.6 trillion (i.e. 39% of EU-27 GDP in 2009. Those public interventions have significant budgetary consequences (strongly felt in Greece, Spain or Italy and imposes a heavy burden on the present and future generations. Therefore there is a strong consensus not only on the level of the European Union but also internationally, that financial sector should contribute to the public finance more fairly. As a reaction on costs of the financial crisis which was paid out from the public money, some of the countries immediately introduced temporary measures in order to collect back paid out money. The aim of the paper is to research the possibility of financial sector taxation, to discuss the proposal of the European Union on the introduction of financial transaction tax on EU level and through the multi-criteria analysis to research, whether this type of the tax is suitable as an own resource of EU budget.

EU Foreign Energy Policy. From Intergovernmentalism to Supranationalism

2012-01-15

The European Union's increasing reliance on imports from third countries is reason for unsettling concern. It is anticipated that by 2030, assuming a continuation of the recent trend, more than 70 per cent of the EU's energy consumption has to be imported. Notwithstanding such anticipation, European regulation addressing the external dimension of energy policy remained far and few between. In practise it is the individual countries being leading actors on the foreign energy relations stage exercising their own respective foreign policies. To cope with these threats to the EU foreign energy policy, the European Commission issued its long anticipated Communication on security of energy supply and international cooperation proposing concrete instruments on how energy foreign relations should be addressed in the future. But - does the Union have the power to bring about the crucial rebound?.

EU — Russia energy cooperation: major development trends and the present state

2013-09-01

Full Text Available The article analyzes the development of EU — Russia energy relations through the lens of the evolution of three parameters: the political agenda (the Energy Dialogue, the institutional structure, and the legal modalities. The identification of these three aspects for assessing the evolution of EU — Russia energy relations is the novelty in the author’s approach. This study aims to identify the previous stages and assess the current state of EU — Russia energy dialogue, since they set out conditions for energy cooperation in the Baltic Sea region. This research is based on a political and legal analysis of various documents and employs various international relations theories (including integration theories. The article demonstrates that the EU nd Russia have made a transition to the integration agenda manifested in the Energy Dialogue (its current goal is the creation of a common European energy market. The author describes the process of gradual consolidation of transgovernmental and transnational institutions, which leads to depoliticization of cooperation and mutual socialization of the partners. Finally, legal discussions on the development of common rules have become more constructive. In sum, the current situation in EU — Russia energy relations is favourable and positively affects cooperation in the Baltic Sea region.

Intra-EU Direct Investment and Enlargement

Directory of Open Access Journals (Sweden)

Festa Andrea

2015-03-01

Full Text Available This paper examines the determinants of the intra-EU direct investment (IDI into the New Member States (NMS using a panel dataset of bilateral capital flows for the period 1993-2013. It is found out by using a simple gravity model that EU membership is the most important determinant. Unlike previous studies including non-EU countries, the distance is insignificant, which is caused by proximity of these countries to one another. A separate analysis focused on subgroups of accession countries gives some evidence that even when size of their economy, distance, institutional quality and EU accession are taken into account, Central European countries receive more IDI than the Baltic and the Balkan states. On the contrary to that, the analysis restricted to the Balkan countries which have joined the EU shows the inexistence of a negative Balkans effect in attracting foreign investment. This finding is relevant because previous studies demonstrate a persistent negative Balkans effect for non-EU Balkan countries and suggests a crucial impact of the EU accession in determining the intra-EU capital flows.

INSTITUTIONS IN TRANSITION: IS THE EU INTEGRATION PROCESS RELEVANT FOR INWARD FDI IN TRANSITION EUROPEAN ECONOMIES?

Directory of Open Access Journals (Sweden)

Uros Delevic

2017-02-01

Full Text Available This research challenges the contemporary view of economic policy makers in transition European economies that the EU integration process will lead to a greater inflow of Foreign Direct Investments (FDI, thereby increasing living standards. With the Brexit referendum, the integration of the EU has been threatened by a distressing existential question: is EU membership valuable for transition countries if even developed countries (like the UK vote to leave or decided not to align like Switzerland and Norway in the past? Our analysis considers the success of several countries in Eastern Europe in attracting and benefiting from FDI on their way to EU membership. Analyzing a 13-year panel data of 16 transition countries, we found no statistically significant positive association between FDI inflow and EU accession. We argue, that it is also important to consider the welfare for domestic economies that can emerge from those investments. We illustrate this through the case study of a successful combination of institutional development and local content policies implementation accompanied by sufficient FDI inflows in a non-EU country - Kazakhstan.

Trade in Value Added (TiVA in EU New Member States (EU NMS

2017-01-01

Full Text Available Contemporary trade analysis indicates the necessity of calculating trade in value added (TiVA which is created through global value chains (GVCs. This paper aims to determine the characteristics and importance of GVC trade in the EU new member states (EU NMS with special emphasis placed on the industry level. The results demonstrate different levels of GVC participation of the EU NMS, where Hungary is the most integrated country and Croatia the least integrated. Regional GVCs exist because a huge part of value added (VA comes from EU member states, as in gross export as well as in final demand (Europe as a hub. The most important source countries are Germany and Italy and there is also evidence of geographical and historical relations between the countries. The domination of backward participation has been found in the analysis made on the industrial level, i.e. the EU NMS are highly dependent on the import of intermediates for the production and export of final products. Strong interconnections between imports of intermediate products and exports of final products have been found in the manufacture of computers, electronics and optical products; manufacture of wood, paper, printing and reproduction. This research has contributed to the scarce literature concerning GVC (TiVA in EU NMS and has opened up new possibilities for further research and analysis.

Next allocation phase of the EU emissions trading scheme: How tough will the future be?

International Nuclear Information System (INIS)

Georgopoulou, E.; Sarafidis, Y.; Mirasgedis, S.; Lalas, D.P.

2006-01-01

The development of National Allocation Plans (NAPs) for the first phase 2005-2007 of the EU emissions trading scheme (EU-ETS) was accompanied by the stated concern of the industrial enterprises with installations that fall under the scope of the relevant Directive 2003/87, since the impacts of the allocation in their financial and technical modes of operation were judged to be severe. Thus, the intensity of the negotiations for the next allocation phase (i.e. 2008-2012), is expected to be heated. With a view to assisting enterprises, especially in the energy sector or for which energy use and its management is a crucial part of their activity, to incorporate in their business plans the impacts of the Directive in an informed manner, an attempt is made here to explore the constraints and the available options that will guide the coming EU-ETS potential allocations. In the analysis, the credits derived from the use of CDM are specifically taken into account. The results show that the next allocations would tend to be significantly more stringent than the current ones because of the combined effect of no inter-period transfer of allowances, the amount of CDM credits expected to be available compared to the amount of effort that would be required and the yield of emission reductions from existing or planned policies and measures. It becomes then crucial, if not imperative, for the enterprises involved as well as national governments to examine carefully means to address their obligations under the Directive

Hyperfine interactions in europium orthophosphate EuPO{sub 4} were investigated using {sup 151}Eu Mössbauer spectroscopy from 6 to 300 K. The value of the quadrupole splitting and the asymmetry parameter were refined and further substantiated by nuclear forward scattering data obtained at room temperature. The temperature dependence of the relative absorption was modeled with an Eu specific Debye temperature of 221(1) K. Eu partial lattice dynamics were probed by means of nuclear inelastic scattering and the mean force constant, the Lamb-Mössbauer factor, the internal energy, the vibrational entropy, the average phonon group velocity were calculated using the extracted density of phonon states. In general, Eu specific vibrations are characterized by rather small phonon energies and contribute strongly to the total entropy of the system. Although there is no classical Debye like behavior at low vibrational energies, the average phonon group velocity can be reasonably approximated using a linear fit.

EU Think Tank Fora as Transaction Cost Reducers: A Study of Informal Interest Intermediation in the EU

Directory of Open Access Journals (Sweden)

Marybel Perez

2014-05-01

Full Text Available By examining the organisational structure of EU think tank fora (seminars, workshops and conferences, this article proposes that fora can play the role of transaction cost reducers in EU policymaking. I argue that certain aspects of EU policymaking, including i controlled processes of consultation, ii diminishing costs of management, and iii the risk of state capture, incentivise EU institutions to outsource part of the consultation activity to policy actors that can help EU institutions fulfil their informational and legitimacy needs. I argue that think tanks are able to play this role because they i reduce information asymmetries by connecting a wide variety of policy actors and ii act as intermediaries that mitigate opportunistic behaviour. The empirical assessment reveals that the dimensions characterising transactions are present in EU think tank fora. It shows that policy actors that do not usually participate in formal consultation processes frequently attend fora where they meet representatives of EU institutions, particularly Parliament and Commission representatives.

In the past eight years, the European Association of Poisons Centres and Clinical Toxicologists (EAPCCT) has been intensively involved in a European Commission led process to develop EU legislation on the information of hazardous products that companies have to notify to EU Poisons Centres (or equivalent "appointed bodies"). As a result of this process, the Commission adopted Regulation (EU) No 2017/542, amending the CLP Regulation by adding an Annex on harmonised product submission requirements. Harmonised mixture information requirements: Detailed and consistent information on the composition of the hazardous product will become available to EU Poisons Centres (PC). The information will be submitted by companies to PCs (or equivalent "appointed bodies") using a web-based software application or in-house software. Two new important features are introduced. Firstly, to be able to rapidly identify the product formula, a Unique Formula Identifier (UFI) on the product label links to the submitted information. Secondly, for better comparability of reports on poisonings between EU member states, a harmonised Product Categorisation System will specify the intended use of a product. Rapid product identification and availability of detailed composition information will lead to timely and adequate medical intervention. This may lead to considerable reduction in healthcare costs. Additionally, for companies trading across the EU, costs of submission of this information will be reduced significantly. Next steps: From 2017, an implementation period has started, consisting of a three-year period for stakeholders to implement the new requirements, followed by a gradual applicability for consumer products (2020), professional products (2021) and industrial use-only products (2024). Technical tools to generate the electronic format and the UFI together with guidance documents are expected to be made available by the end of 2017 by the European Chemicals Agency (ECHA).

Lead poisoning from the ingestion of spent lead shot is well documented in waterfowl (Sanderson and Bellrose 1986) and has been reported in other wetland (Locke et al. 1991, Windingstad et al. 1984) and upland (Hunter and Rosen 1965, Locke and Bagley 1967) avian species. Ingested fishing weights have been implicated in lead poisoning of Trumpeter Swans (Cygnus buccinator) (Blus et al. 1989), Common Loons (Gavia immer) (Locke et al. 1982, Franson and Cliplef 1992, Pokras and Chafe1 1992), Mute Swans (Cygnus olor) (Birkhead 1982), and Sandhill Cranes (Grus canadensis) (Windingstad et al. 1984). The significance of lead poisoning as a mortality factor in avian species other than waterfowl is probably underestimated (Locke and Friend 1992), and any cause of mortality becomes particularly important in species with small population sizes. We report here the first known case of lead poisoning in a Mississippi Sandhill Crane (Grus canadensis pulla), a critically endangered subspecies.

Up to now, orchestrating the coexistence of Eu 2+ and Eu 3+ activators in a single host lattice has been an extremely difficult task, especially for the appearance of the characteristic emission of Eu 2+ and Eu 3+ in order to generate white light. Nevertheless, here we demonstrate a new Eu 2+ /Eu 3+ coactivated SrAl 3 BO 7 nanocrystalline phosphor with abundant and excellent multichannel luminescence properties. A series of Eu 2+ /Eu 3+ coactivated SrAl 3 BO 7 nanocrystalline phosphors were prepared through a Pechini-type sol-gel method followed by a reduction process. With excitation of UV/NUV light, the prepared SrAl 3 BO 7 :Eu 2+ ,Eu 3+ phosphors show not only the characteristic f-f transitions of Eu 3+ ion ( 5 D J → 7 F J,J' , J, J' = 0-3), but also the 5d → 4f transitions of Eu 2+ ion with comparable intensity from 400 to 700 nm in the whole visible spectral region. The luminescence color of the SrAl 3 BO 7 :Eu 2+ ,Eu 3+ phosphor can be tuned from blue, blue-green, white, and orange to orange-red by changing the excitation wavelength, the overall doping concentration of europium ions (Eu 2+ , Eu 3+ ), and the relative ratio of Eu 2+ to Eu 3+ ions to some extent. A single-phase white-light emission has been realized in SrAl 3 BO 7 :Eu 2+ ,Eu 3+ phosphor. The obtained SrAl 3 BO 7 :Eu 2+ ,Eu 3+ phosphor has potential application in the area of NUV white-light-emitting diodes.

The Impact of the Explosion of EU News on Voter Choice in the 2014 EU Elections

Directory of Open Access Journals (Sweden)

2016-02-01

Full Text Available The European elections in 2014 were the first to be held after a long period in which EU-related news was prominent in the media. They were held after years of daily news about the euro crisis and after months of news about the popular uprising in the Ukraine against president Yanukovych, who had refused to sign the association agreement with the EU. This could have invited political parties to overcome the usual problem of low salience of EU issues by strongly profiling themselves on EU issues. Turnout at the 2014 EU elections, however, remained low, hinting that parties were unable to convert the attention for European issues into enthusiasm for their party at the European elections. This paper asks how vote choice was influenced by party campaigning on EU related issues. A news effects analysis based on a content analysis of Dutch newspapers and television, and on a panel survey among Dutch voters revealed that EU issues functioned as wedge issues: the more strongly parties were associated in the news with the euro crisis and the Ukraine, the less they succeeded in mobilizing voters.

LaVO 4 phosphors were synthesized by using a solid state reaction, and were characterized by using X-ray diffraction (XRD), scanning electron microscopy (SEM) and photoluminescence (PL). The XRD patterns of the Li-doped LaVO 4 :Eu 3+ powder phosphors revealed a mixture of tetragonal and monoclinic phases. The tetragonal phase of the LaVO 4 :Eu 3+ phosphor showed a higher PL intensity than the monoclinic one, despite the presence of both monoclinic and tetragonal structures. The Li-doped LaVO 4 :Eu 3+ powder phosphors absorbed strongly at 396 nm and exhibited strong red emission at approximately 619.5 nm due to the 5 D 0 → 7 F 2 transition. The incorporation of Li + ions into the LaVO 4 :Eu 3+ powder can lead to a remarkable increase in photoluminescence. The enhanced luminescence is attributed to the incorporation of Li + ions that may act as a sensitizers for effective energy transfer. This phosphor has promising applications in near-UV light-emitting diodes(LEDs).

A liquid Eu precursor, bis(normal-propyl-tetramethylcyclopentadienyl)europium has been synthesized. This precursor exists as a liquid at temperatures higher than 49 °C, has a moderately high vapor pressure, contains no oxygen in its molecular structure, and can be distilled to high purity. These properties make it ideal for doping using a chemical vapor or atomic layer deposition method, and provide a degree of control previously unavailable. As a precursor the Eu exists in the divalent valance state, however, once doped into GaN by organometallic vapor phase epitaxy, the room-temperature photoluminescence of the Eu-doped GaN exhibited the typical red emission due to the intra-4f shell transition of trivalent Eu. After variation of the growth temperature, it was found that divalent Eu could be stabilized in the GaN matrix. By tuning the Fermi level through donor doping, the ratio of Eu{sup 2+} to Eu{sup 3+} could be controlled. The change in valence state of the Eu ions was confirmed using X-ray absorption near-edge structure. - Highlights: • A liquid Eu precursor was synthesized and its properties were characterized. • Precursor has a low melting point and a moderately high vapor pressure. • Does not contain oxygen in its molecular structure. • Eu can changed its valance state when incorporated into GaN. • Valence state of Eu in GaN can be controlled by donor doping.

TiO2(Eu)/CuO nanocomposites were prepared by precipitation method. The anatase nanocrystallites with a size of 26 nm exhibited well crystallized and characteristical dipyramidal morphology and {1 0 1} and {0 0 1} faceting. Transmission electron microscopy photographs with atomic resolution showed that the Eu(III) dopants were bounded on surface of titania. In the composites, the CuO nanocrystals exhibiting a monoclinic tenorite structure with a size in the range from 2 to 5 nm were grafted to the surface of titania. The influence of copper(II) oxide led to distinct selectivity in the photocatalytic and antimicrobial properties of the investigated TiO2(Eu)/CuO nanocomposites. While the presence of CuO nanocrystals strongly increased the photocatalytic production of hydrogen by ethanol reforming, it decreased the activity in photoinduced total mineralization of phenol comparing with non-modified TiO2(Eu). In investigated TiO2(Eu)/CuO powders, the photoinduced antimicrobial activity against membranes of Enterococcus species was influenced by the selective binding of CuO to the surface of the microorganism leading to distinct selectivity in their action. The activity against Enterococcus faecalis was higher than against Enterococcus faecium.

Chemical exchange saturation transfer (CEST) properties of albumin-binding and gold nanoparticle-bound Eu (III) chelates

Science.gov (United States)

Melendez, Milleo Dalmacio

CEST agents derived from paramagnetic complexes, commonly referred to as PARACEST agents represent a new class of MRI contrast agents that respond to biological information such as pH, temperature, redox, and metabolite levels. In this work, CEST properties of two novel PARACEST agents were investigated upon binding to human serum albumin (HSA) and conjugation to gold nanoparticles (Au NPs). CEST properties of [EuDOTA(O-Et-Tyr)4] -when bound to HSA was studied to address the effect of proteins on CEST. The interaction of this Eu3+ complex to HSA was investigated by performing fluorescent probe displacement studies and it was found to bind HSA at two different binding pockets, the normal warfarin and dansyl glycine binding sites. The lipophilic pendant arms and the negative charge of this complex contribute to the favorable protein binding. However, the CEST signal was reduced 2-fold upon binding to HSA. The exchangeable protons on HSA provide a large proton pool that can exchange with the bound H 2O, competing for the exchange between bulk and bound water. Au NPs coated with [EuDOTA(CAM)4]3+ were prepared using the Brust method and characterized by measuring the CEST properties. The water residence lifetime for the Au-Eu NP conjugates increased 2-fold compared to the free Eu3+ complex presumably, as a result of the formation of hindered structure between the particle and the Eu3+ complex. Sensitivity enhancement in CEST was achieved by slowing down water exchange and increasing the number of exchangeable groups on the agent using Au-Eu NP conjugates. The CEST properties of small molecule PARACEST agents were shown to vary depending on the platform used in assembling larger adducts.

Eu{sup 3+} and Eu{sup 2+} co-doped calcium aluminosilicate glass–ceramics have been prepared by devitrification of calcium aluminosilicate glass using heat-treatment. Control of crystallization in the glass–ceramics was studied by X-ray diffraction (XRD) and Raman spectroscopy. The results showed that crystalline phases in glass–ceramic belong to the family of melilite Ca{sub 2}Mg{sub 0.25}Al{sub 1.5}Si{sub 1.25}O{sub 7} as the major phase and anorthite CaAl{sub 2}Si{sub 2}O{sub 8} as the minor phase. Luminescent properties were investigated by emission; lifetime and the color points were calculated. Emission spectra showed that Eu{sup 2+} entered into the crystalline phase in a two steps mechanism: first as Eu{sup 3+} which is then reduced to Eu{sup 2+}. This incorporation in the crystal enhanced Eu{sup 2+} emission with increasing time of heat-treatment and therefore crystallization. - Highlights: • Crystallization of doped glass–ceramics by heat-treatment controlled by microRaman. • Crystalline phases consist of melilite and anorthite. • Eu{sup 3+} and Eu{sup 2+} emissions characterized by their lifetime and color indexes. • Crystallization process modified efficiently the emission color point.

Consequences of EU air quality directives for spatial development plans in various EU countries

Over the past few years, the highest Dutch court of justice has rejected many building plans for new homes, roads and businesses because of reasons related to EU air quality limit values. This has made it clear that detailed impact assessments are necessary to having plans approved for permits, and that failure to achieve limit values can be a reason to reject a plan. An investigation to see whether such issues have also played a role in other EU countries has proven the contrary. Only a few similar court cases have taken place in other countries, while air quality limit values are breached in other EU countries as well. The reason is that the Netherlands has implemented the first EU Daughter Directive in a relatively strict manner in comparison to other countries, in particular: Adopting a strict legal coupling of air quality and spatial planning policies, with many types of plans being subject to an air quality impact assessment; Perceiving limit values as absolute limit values, whereas in many other countries a need to meet a limit value is weighted with other interests in granting permits; Applying limit values to the whole country. Although this application is, in principle, valid for all EU member states, some member states apply limit values only to locations where people can be exposed; Since air quality assessment is detailed in the Netherlands, many locations are appointed where air quality limit values are breached. Clearly, the role of limit values in granting permits for plans differs considerably among the EU countries, while the underlying EU legislation is the same, and while limit values are breached in other countries as well [nl

2013-08-01

Straw mushrooms were grown on lead contaminated rice straw and stubble. Study materials were dried, acid digested, and analyzed for lead using flame atomic absorption spectrophotometry. The results showed the highest lead concentration in substrate was 445.350 mg kg⁻¹ in Treatment 3 (T3) and the lowest was BD (below detection) in Treatment 1 (T1). The maximum lead content in straw mushrooms was 5.072 mg kg⁻¹ dw in pileus of T3 and the minimum lead content in straw mushrooms was BD in egg and mature (stalk and pileus) stage of T1. The lead concentration in straw mushrooms was affected by the age of the mycelium and the morphology of mushrooms. Mushrooms' lead uptake produced the highest accumulation in the cell wall. Some lead concentrations in straw mushrooms exceeded the EU standard (>3 mg kg⁻¹ dw).

Using tetrabutyl titanate as precursor, Eu 3+ doped TiO 2 nano-powder was prepared by sol-gel method, the nature of luminescence of nano-powder was studied. The interaction of chlorpyrifos with Eu 3+ doped TiO 2 was studied by absorption and fluorescence spectroscopy. The results indicated the fluorescence intensity of Eu 3+ doped TiO 2 was quenched by chlorpyrifos and the quenching rate constant (kq) was 1.24Χ10 11 L/mol·s according to the Stern-Volmer equation. The dynamics of photoinduced electron transfer from chlorpyrifos to conduction band of TiO 2 nanoparticle was observed and the mechanism of electron transfer had been confirmed by the calculation of free energy change (ΔG et ) by applying Rehm-Weller equation as well as energy level diagram. A new rapid method for detection of chlorpyrifos was established according to the fluorescence intensity of Eu 3+ doped TiO 2 was proportional to chlorpyrifos concentration. The range of detection was 5.0Χ10 -10 -2.5Χ10 -7 mol/L and the detection limit (3σ) was 3.2Χ10 -11 mol/L

Biomass for electricity in the EU-27: Potential demand, CO2 abatements and breakeven prices for co-firing

International Nuclear Information System (INIS)

Bertrand, Vincent; Dequiedt, Benjamin; Le Cadre, Elodie

2014-01-01

This paper analyses the potential of biomass-based electricity in the EU-27 countries, and interactions with climate policy and the EU ETS. We estimate the potential biomass demand from the existing power plants, and we match our estimates with the potential biomass supply in Europe. Furthermore, we compute the CO2 abatement associated with the co-firing opportunities in European coal plants. We find that the biomass demand from the power sector may be very high compared with potential supply. We also identify that co-firing can produce high volumes of CO 2 abatements, which may be two times larger than that of the coal-to-gas fuel switching. We also compute biomass and CO2 breakeven prices for co-firing. Results indicate that biomass-based electricity remains profitable with high biomass prices, when the carbon price is high: a Euros 16–24 (25–35, respectively) biomass price (per MWh prim ) for a Euros 20 (50, respectively) carbon price. Hence, the carbon price appears as an important driver, which can make profitable a high share of the potential biomass demand from the power sector, even with high biomass prices. This aims to gain insights on how biomass market may be impacted by the EU ETS and others climate policies. - Highlights: • Technical potential of biomass (demand and CO 2 abatement) in European electricity. • Calculation for co-firing and biomass power plants; comparison with potential biomass supply in EU-27 countries. • Calculation of biomass and CO 2 breakeven prices for co-firing. • Potential demand is 8–148% of potential supply (up to 80% of demand from co-firing). • High potential abatement from co-firing (up to 365 Mt/yr); Profitable co-firing with €16-24 (25–35) biomass price for €20 (50) CO 2 price

Can EU Act as a Democracy Promoter? Analysing the Democratization Demand and Supply in Turkey - EU Relations

Directory of Open Access Journals (Sweden)

Çiğdem Üstün

2017-06-01

Full Text Available The EU’s role to assist Turkey in its democratization efforts has been debated during Turkey’s candidacy. However, in the second decade of the 21st century, this role of the EU lost its visibility while Turkey seemed to lose its interest in reform movements. This paper, inspired by Pevehouse, defines the EU as a supplier of democratization mechanisms and Turkey as an actor in need. Although lack of enthusiasm and disengagement have come to characterize Turkey-EU relations, this study aims to demonstrate that there are differences between the governing and the opposition actors’ views on the EU and its role in the democratization of Turkey. Data collected from the speeches of opposition parties’ parliamentarians between 1 January 2011 and 31 August 2016 demonstrates the similarities observed in these parties’ concerns regarding democratic practices and the perception of the EU as an actor strengthening democracy, while indicating that the EU, as a supplier, overlooked their concerns during the process.

Luminescence Properties of Ca19Ce(PO4)14:A (A = Eu3+/Tb3+/Mn2+) Phosphors with Abundant Colors: Abnormal Coexistence of Ce4+/3+-Eu3+ and Energy Transfer of Ce3+ → Tb3+/Mn2+ and Tb3+-Mn2.

2017-06-05

A series of Eu 3+ /Tb 3+ /Mn 2+ -ion-doped Ca 19 Ce(PO 4 ) 14 (CCPO) phosphors have been prepared via the conventional high-temperature solid-state reaction process. Under UV radiation, the CCPO host presents a broad blue emission band from Ce 3+ ions, which are generated during the preparation process because of the formation of deficiency. The Eu 3+ -doped CCPO phosphors can exhibit magenta to red-orange emission as a result of the abnormal coexistence of Ce 3+ /Ce 4+ /Eu 3+ and the metal-metal charge-transfer (MMCT) effect between Ce 3+ and Eu 3+ . When Tb 3+ /Mn 2+ are doped into the hosts, the samples excited with 300 nm UV light present multicolor emissions due to energy transfer (ET) from the host (Ce 3+ ) to the activators with increasing activator concentrations. The emitting colors of CCPO:Tb 3+ phosphors can be tuned from blue to green, and the CCPO:Mn 2+ phosphors can emit red light. The ET mechanism from the host (Ce 3+ ) to Tb 3+ /Mn 2+ is demonstrated to be a dipole-quadrapole interaction for Ce 3+ → Tb 3+ and an exchange interaction for Ce 3+ → Mn 2+ in CCPO:Tb 3+ /Mn 2+ . Abundant emission colors containing white emission were obtained in the Tb 3+ - and Mn 2+ -codoped CCPO phosphors through control of the levels of doped Tb 3+ and Mn 2+ ions. The white-emitted CCPO:Tb 3+ /Mn 2+ phosphor exhibited excellent thermal stability.

2015-07-01

The new Council Directive 2013/59/EURATOM regarding radiation protection (EU-BSS) contains comprehensive regulations regarding radon protection in dwellings, in public buildings, and at workplaces for the first time. Key elements are the specification of a reference level of maximum 300 Bq/m{sup 3}, the establishment of a national radon action plan, and a more comprehensive regulation of radon protection at workplaces and public buildings. The radon action plan shall contain strategies and measures regarding for example the estimation of the distribution of indoor radon concentrations, the mapping of radon, the radon risk communication strategy, the assignment of responsibilities, and regular reviews of the action plan. The new EU-BSS often requires only the establishment of strategies and the specification of measures, leaving the precise content of the strategies and measures to the member states. This gives the member states flexibility for the implementation of the EU-BSS into national legislation and allows to account for specific national experiences and circumstances. This contribution discusses and evaluates - based on the existing regulations concerning radon protection in Austria - the effectiveness of different new measures and regulations with respect to reducing the radon risk in Austria. Furthermore, their feasibility and practicability in terms of administrative and financial effort will be discussed. Thus, efficient new measures which lead to an improvement of the current radon control system will be identified.

We report the change in the valency of Eu-ions in the binary intermetallic cubic compound EuPd{sub 3} induced by La doping at rare-earth sites. Doping of La generates negative chemical pressure in the lattice, resulting in a significant increase of the lattice parameter without altering the simple-cubic structure of the compound. Results of dc-magnetic measurements suggest that this increase in the lattice parameter is associated with the valence transition of Eu-ions from Eu{sup 3+} to a mixed-valent state. As Eu{sup 2+}-ions possess a large magnetic moment, this valence transition significantly modifies the magnetic behavior of the compound. In contrast to introducing boron at the vacant body center site of the unit cell to change the valency of Eu-ions, as in the case of EuPd{sub 3}B, our results suggest it can also be altered by doping a rare-earth ion of larger size at the lattice site of Eu in EuPd{sub 3}.

Intra-EU agricultural trade, virtual water flows and policy implications.

Science.gov (United States)

Antonelli, M; Tamea, S; Yang, H

2017-06-01

The development of approaches to tackle the European Union (EU) water-related challenges and shift towards sustainable water management and use is one of the main objectives of Horizon 2020, the EU strategy to lead a smart, sustainable and inclusive growth. The EU is an increasingly water challenged area and is a major agricultural trader. As agricultural trade entails an exchange of water embodied in goods as a factor of production, this study investigates the region's water-food-trade nexus by analysing intra-regional virtual water trade (VWT) in agricultural products. The analysed period (1993-2011) comprises the enactment of the Water Framework Directive (WFD) in the year 2000. Aspects of the VWT that are relevant for the WFD are explored. The EU is a net importer of virtual water (VW) from the rest of the world, but intra-regional VWT represents 46% of total imports and 75% of total exports. Five countries account for 60% of total VW imports (Germany, France, Italy, The Netherlands, Belgium) and 65% of total VW exports (The Netherlands, France, Germany, Belgium and Spain). Intra-EU VWT more than doubled over the period considered, while trade with extra-EU countries did not show such a marked trend. In the same period, blue VWT increased significantly within the region and net import from the rest of the world slightly decreased. Water scarce countries, such as Spain and Italy, are major exporters of blue water in the region. The traded volumes of VW have been increasing almost monotonically over the years, and with a substantial increase after 2000. The overall trend in changes in VWT does not seem to be in accordance with the WFD goals. This study demonstrated that VWT analyses can help evaluate intertwining effects of water, agriculture and trade policies which are often made separately in respective sectors.

Highlights: • Lead phosphate glasses doped with rare earth ions were prepared. • The local structure was examined using X-ray diffraction and spectroscopic methods. • Different structural phosphate groups are present in lead phosphate glasses. • The electron–phonon coupling strength and phonon energy of the glass host was determined. • Several observed emission bands are due to 4f–4f electronic transitions of rare earth ions. -- Abstract: Lead–gallium phosphate glasses doped with rare the earth ions (Eu 3+ , Dy 3+ , Tb 3+ , Er 3+ ) were synthesized. The structure of obtained glasses was examined by means of use: X-ray diffraction (XRD), nuclear magnetic resonance ( 207 Pb and 31 P NMR), fourier transform infrared (FT-IR) and Raman spectroscopy. In contrast to fully amorphous Ln-doped samples (Ln = Eu, Dy, Tb), in Er-doped sample the GaPO 4 crystalline phase was identified. It was found from the NMR, FT-IR and Raman spectroscopic techniques that, different structural phosphate groups were present in lead phosphate glasses. Based on absorption measurements, the UV–VIS cut-off wavelength for lead phosphate glass was determined and its value is close to 305 nm. Excitation and emission spectra of rare earths were also detected. From excitation spectra of Eu 3+ the electron–phonon coupling strength and phonon energy of the glass host were determined. Due to 4f 6 –4f 6 (Eu 3+ ), 4f 8 –4f 8 (Tb 3+ ), 4f 9 –4f 9 (Dy 3+ ) and 4f 11 –4f 11 (Er 3+ ) electronic transitions of trivalent rare earth ions several luminescence bands were stated

Controlled formation of aggregates having organized structure of cube-shaped EuS nanocrystals is reported. The EuS aggregates in liquid media (methanol) were obtained by means of van der Waals interaction between EuS nanocrystals. The packing structure of the EuS aggregates is characterized with transmission electron microscopy (TEM) and small angle X-ray scattering measurements (SAXS). TEM image indicates the EuS nanocrystals form self-aggregated 2D orthogonal lattice structure. The diffraction peak of (111) of SAXS profile shows that the cube-shaped EuS form 3D cubic superlattice. We successfully demonstrated that the aggregates of cube-shaped EuS nanocrystals formed cubic stacking structure.

The transport and magnetic properties of Eu{sub 0.6}Ca{sub 0.4}B{sub 6} single crystals have been studied at temperatures 1.8-300 K in magnetic fields up to 80 kOe. It was found that lowering of temperature results in a drastic increase of magnetoresistance up to the values of {rho}(0)/{rho}(H){approx}7{center_dot}10{sup 5} detected below 6K. The Hall and Seebeck effect measurements showed that colossal magnetoresistance (CMR) observed in Eu{sub 0.6}Ca{sub 0.4}B{sub 6} is accompanied by a crossover from hole-like to electron-like regime of charge transport induced by applied magnetic field. Hall mobility values {mu}{sub H{approx}}200-350 cm{sup 2}/(Vs) estimated for the high conductive state of Eu{sub 0.6}Ca{sub 0.4}B{sub 6} in the presence of strong substitutional disorder were proved to be comparable with these ones measured for undoped EuB{sub 6}.

The syntheses and crystal structures of the two isotypic europium(II) oxide halides Eu{sub 2}OBr{sub 2} and Eu{sub 2}OI{sub 2} are reported. They crystallize orthorhombically in the space group Ibam (Z=4; Eu{sub 2}OBr{sub 2}: a=709.86(5), b=1200.34(9), c=628.71(4) pm; Eu{sub 2}OI{sub 2}: a=739.78(5), b=1295.13(9), c=644.82(4) pm). The unit cell parameters presented here, and thus the interatomic distances of Eu{sub 2}OI{sub 2}, are significantly smaller than the ones reported in the literature, which is explained by the substitution of europium with larger barium cations due to the synthesis route described in the early study. Central building blocks of both crystal structures are trans-edge-connected [OEu{sub 4}]{sup 6+} tetrahedra forming straight {sup 1}{sub ∞}{[OEu"e_4_/_2]"2"+} chains running parallel to the [001] direction. Bundled like a hexagonal rod packing, their interaction is achieved by Br{sup -} or I{sup -} anions for charge compensation.

Highlights: • Nanocomposites composed of Eu-doped anatase grafted with CuO. • Increase in photocatalytic hydrogen production due to CuO acting as electrons sink. • CuO in composites decreasing the photoinduced total mineralization of phenol. • Selective photoinduced antimicrobial activity against Enterococcus species. - Abstract: TiO 2 (Eu)/CuO nanocomposites were prepared by precipitation method. The anatase nanocrystallites with a size of 26 nm exhibited well crystallized and characteristical dipyramidal morphology and {1 0 1} and {0 0 1} faceting. Transmission electron microscopy photographs with atomic resolution showed that the Eu(III) dopants were bounded on surface of titania. In the composites, the CuO nanocrystals exhibiting a monoclinic tenorite structure with a size in the range from 2 to 5 nm were grafted to the surface of titania. The influence of copper(II) oxide led to distinct selectivity in the photocatalytic and antimicrobial properties of the investigated TiO 2 (Eu)/CuO nanocomposites. While the presence of CuO nanocrystals strongly increased the photocatalytic production of hydrogen by ethanol reforming, it decreased the activity in photoinduced total mineralization of phenol comparing with non-modified TiO 2 (Eu). In investigated TiO 2 (Eu)/CuO powders, the photoinduced antimicrobial activity against membranes of Enterococcus species was influenced by the selective binding of CuO to the surface of the microorganism leading to distinct selectivity in their action. The activity against Enterococcus faecalis was higher than against Enterococcus faecium.

The expanding EU

Europe has always been much diversified, and therefore it is not possible to define a European...... identity in terms of particular cultural traditions. However, in spite of their diversity, the EU-member countries are united by their adherence to the principles of democracy, rule by law and human rights.

Eu and Eu:Yb codoped ZnO nanocrystals embedded in B(2)O(3) glass matrix were synthesized and their structural, optical properties were discussed. On excitation with 532 nm laser radiation intense orange/red emissions from Eu(3+) ions were observed. The fluorescence intensity was found to enhance on annealing. Frequency upconversion emissions from Eu(3+) ions were observed in presence of Yb(3+) ions on excitation with NIR (976 nm) laser. The enhancement in emission intensity was explained and the photo-physics involved is linked with the unique structural properties of the crystallites formed. Ion interactions and the different energy transfer parameters were also calculated. Copyright © 2012 Elsevier B.V. All rights reserved.

1989-01-01

Experimental study of concentrational depolarization luminescence (CDL) of phosphate and germanate glasses, containing Eu 3+ ions, has been carried out. On the basis of three-body self-consistent approximation the theory of CDL is conceived, which takes into account Eu-Eu interaction of higher multipolarities. By comparing the theory with the experiment energy transfer radii for Eu-Eu dipole-dipole, dipole-quadrupole and quadrupole-quadrupole interactions are determined. The attempt to discriminate Eu-Eu interaction types in the studied range of Eu 3+ ion concentration change has failed owing to law accuracy of luminescence emittance anisotropy measurement

Refugee Quota Trading within the Context of EU-ENP Cooperation: Rational, Bounded Rational and Ethical Critiques

Directory of Open Access Journals (Sweden)

Mollie Gerver

2013-02-01

Full Text Available In 1997 Peter Schuck proposed a ‘refugee quota trading’ mechanism, whereby countries voluntarily form a union, each country accepting a quota of refugees and able to buy and sell the quota to other states within and even outside of the union. Today, the EU arguably has a de facto cash transfer mechanism both within the EU and between the EU and European Neighbourhood Policy countries. This article explores the question of refugee quota trading, explaining why current EU policy fails to increase refugee protection. Throughout the critique, states are treated either as rational actors or actors with present-preference bias, the latter largely ignored in current discussions on international refugee ‘burden sharing’. In addition, the ethics of refugee quota trading is presented using arguments distinct from that of Anker et al. (1998 who argue that refugee quota trading creates a ‘commodification’ of refugees. One could argue that refugees’ protection is being commodified, not refugees themselves. However, when states are provided funds not to deport refugees, this can be a type of reward for not taking an action that states ought to follow regardless of the reward. Just as there are non-utilitarian reasons not to rely on rewards alone for lowering the crime rates for heinous crimes within states, there may be non-utilitarian arguments against refugee quota trading.

Self‐consistent dynamic and static calculations have here been performed for EuO, which is an ideal Heisenberg magnet with significant second‐nearest‐neighbor interaction (J2 = J1/5). The two‐pole approximation...... a cutoff of the spectrum at high frequencies, which cannot be seen experimentally, but which significantly influences the frequency moments. It was found that the finite J2 has significant importance for a comparison between theory and experiment. It is concluded that the calculation for a simple cubic n.......n. magnet by Hubbard3) does not describe the EuO data accurately, neither with respect to line shape nor frequency scale. Significant differences are to be expected between EuO and EuS having opposite sign for J2....

A trend towards automation of scientific research has recently resulted in what has been termed "data-driven inquiry" in various disciplines, including physics and biology. The automation of many tasks has been identified as a possible future also for the humanities and the social sciences, particularly in those disciplines concerned with the analysis of text, due to the recent availability of millions of books and news articles in digital format. In the social sciences, the analysis of news media is done largely by hand and in a hypothesis-driven fashion: the scholar needs to formulate a very specific assumption about the patterns that might be in the data, and then set out to verify if they are present or not. In this study, we report what we think is the first large scale content-analysis of cross-linguistic text in the social sciences, by using various artificial intelligence techniques. We analyse 1.3 M news articles in 22 languages detecting a clear structure in the choice of stories covered by the various outlets. This is significantly affected by objective national, geographic, economic and cultural relations among outlets and countries, e.g., outlets from countries sharing strong economic ties are more likely to cover the same stories. We also show that the deviation from average content is significantly correlated with membership to the eurozone, as well as with the year of accession to the EU. While independently making a multitude of small editorial decisions, the leading media of the 27 EU countries, over a period of six months, shaped the contents of the EU mediasphere in a way that reflects its deep geographic, economic and cultural relations. Detecting these subtle signals in a statistically rigorous way would be out of the reach of traditional methods. This analysis demonstrates the power of the available methods for significant automation of media content analysis.

Our main findings suggest that Kazakhstan's mass media positively perceives the role of the EU in the region. Moreover, they tend to portray the EU mainly as an economic powerhouse. Our findings support some suggestions by similar studies of the EU's external perception.

EU, Eastern Europe and Values Imperialism

Directory of Open Access Journals (Sweden)

Stephen White

2014-01-01

Full Text Available This paper proposes an idea of'values imperialism'as a helpful way of conceptualising the relationship between the EU and the states that came within its sphere of influence after the end of the Cold War, particularly its 'neighbours' in Eastern Europe. Values imperialism places its emphasis on the 'superstructure', including norms, laws and social practices. EU larger objective was that the assumptions about government and ownership that were favoured by the dominant powers (EU and the West in the broad term should be absorbed and recapitulated by those countries that were subordinate. The broad framework ofsubordination was established by the Partnership and Cooperation Agreements that began to be concluded from 1994 onwards. Patterns of'values imperialism'could also be discovered in the EU Common Strategies on Russia and Ukraine that were adopted in 1999. Article also points out several cases when the EU intervened directly in the domestic affairs of the Eastern Europe countries in a manner that was not always compatible with the provisions on state sovereignty: a 'European Instrument for Democracy and Human Rights', launched in 2006, interventions ofEU representatives in the work of local courts and organisation of exit polls, which could be used to discredit the official election results and in this way to undermine the position of local governments. Finally, the author concludes that the EU used 'values imperialism'practices in order to extend its influence, particularly in the Eastern Europe.

We study the valence band of Eu-intercalated C60 by synchrotron radiation photoelectron spectroscopy to un-derstand the ferromagnetism (FM) and the giant magnetoresistance (GMR) of Eu6C60. The results reveal the semiconducting property and the remarkable 5d6s-π hybridization. Eu-C60 bonding has both ionic and covalent contributions. No more than half the 5d6s electrons transfer from Eu to the LUMO derived band of C60, and the LUMO+1 derived band is not filled. The remaining valence electrons of Eu, together with some π (LUMO, HOMO and HOMO-1) electrons, constitute the covalent bond. The electronic structure implies that the magnetic coupling in Eu6C60 should be through the intra-atomic f-sd exchange and the medium of the π electrons. The possibility of the GMR being tunnelling magnetoresistance is ruled out.

Near infrared (NIR) quantum cutting involving the down conversion of an absorbed visible photon to emission of two NIR photons was achieved in SrAl{sub 2}O{sub 4}:0.01Eu{sup 2+}, xYb{sup 3+} (x=0, 1, 2, 5, 10, 20, 30 mol%) samples. The photoluminescence properties of samples in visible and NIR regions were measured to verify the energy transfer (ET) from Eu{sup 2+} to Yb{sup 3+}. The results demonstrated that Eu{sup 2+} was an efficient sensitizer for Yb{sup 3+} in the SrAl{sub 2}O{sub 4} host lattice. According to Gaussian fitting analysis and temperature-dependent luminescence experiments, the conclusion was drawn that the cooperative energy transfer (CET) process dominated the ET process and the influence of charge transfer state (CTS) of Yb{sup 3+} could be negligible. As a result, the high energy transfer efficiency (ETE) and quantum yield (QY) have been acquired, the maximum value approached 73.68% and 147.36%, respectively. Therefore, this down-conversion material has potential application in crystalline silicon solar cells to improve conversion efficiency. - Graphical abstract: Near infrared quantum cutting was achieved in Eu{sup 2+}–Yb{sup 3+} co-doped SrAl{sub 2}O{sub 4} samples. The cooperative energy transfer process dominated energy transfer process and high energy transfer efficiency was acquired. - Highlights: • The absorption spectrum of Eu{sup 2+} ion is strong in intensity and broad in bandwidth. • The spectra of Eu{sup 2+} in SrAl{sub 2}O{sub 4} lies in the strongest region of solar spectrum. • The cooperative energy transfer (CET) dominated the energy transfer process. • The domination of CET is confirmed by experimental analysis. • SrAl{sub 2}O{sub 4}:Eu{sup 2+},Yb{sup 3+} show high energy transfer efficiency and long lifetime.

The novel polyphosphide, EuP/sub 7/, was prepared under controlled conditions by reaction of the elements in salt melts at 750-800 K. EuP/sub 7/ forms black prismatic crystals not attacked by dilute mineral acids and bases. The thermal decomposition yields EuP/sub 3/ at 700 K and in further steps EuP/sub 2/, Eu/sub 3/P/sub 4/ and EuP, respectively. According to the crystal structure as well as the electrical, optical and magnetic properties, EuP/sub 7/ is a semiconductor (Esub(G) = 0.9 eV; Esub(G) (vert) = 1.1 eV) with divalent europium (..mu.. = 7.55 B.M.). The compound crystallizes in the monoclinic space group P 2/sub 1//n with a = 1148.8(7) pm, b = 570.0(3) pm, c = 1061.0(6) pm, and ..beta.. = 106.08/sup 0/(5); (X-ray diffraction data; 1479 hkl; R = 0.031). The P-atoms are connected ((P-P) = 218.0-223.5 pm) to a 2-dimensional infinite polyanionic structure 2sub(infinity)(P/sub 7//sup 2 -/) with homonuclear 3-bonded and 2-bonded P-atoms in the ratio 5 : 2. The polyanionic network contains P/sub 6/-rings (chair conformation) as well as P/sub 8/-rings and P/sub 10/-rings. The Eu-atoms are bonded to 9 P-atoms (1,4,4-polyhedra) with bond distances ranging from 306.6 to 326.6 pm. The Eu-atoms complete the tetrahedral environment of the P-atoms.

MTU engines for locomotives satisfying the EU stage IIIB emission standard; MTU-Lokomotivantriebe fuer die Emissionsstufe EU IIIB

The emission limits for diesel locomotives inside the European Union are included within the scope of Directive 97/68/EC, which is sometimes referred to as the ''non-road directive''. The pollutants limited by it are NO{sub x}, particulates, CO and HCs. The aim, through the directive, is to reduce railway emissions by a factor of ten by the year 2020. The EU stage IIIB standard is due to take effect on 1 January 2012. This envisages a further drastic reduction in limit values compared with EU stage IIIA, which is applicable today. For diesel locomotives, EU stage IIIA only came into force as recently as 2009. The manufacturers of engines and locomotives are thus having to face up to the huge challenge of getting the technologies needed for EU stage IIIB ready for the production line within a period of only three years. MTU has succeeded in developing engines for diesel locomotives that comply with the EU stage IIIB emission standard, which appreciably lower emissions compared with engines satisfying EU stage IIIA, thanks to the incorporation of the most modern technologies available, and has even gone as far as preparing them for the EU stage IV, the next one to come into force.

Europe, the EU and its 2050 Energy Storylines

This paper seeks to explore some of the conditions under which energy policy could be formulated in and by the European Union (EU) over the next 40 years. The development of energy policy at the EU level is addressed from a wider historical perspective, taking into account a number of factors that influence both the EU project and its energy supply security. These factors include the EU's international orientation and cooperation; the EU 'economic community of law' paradigm; the EU's (failing?) external leadership role; the impact of the fall of the Berlin Wall; and Europe's talents for creativity and improvisation. These factors are discussed in somewhat greater depth in the context of the formulation of an all-EU energy policy. The global energy policy environment is briefly discussed, indicating that energy resources for the world are less at stake than their access. On this basis, a closer look is taken at the theoretical and practical aspects of using scenarios as a tool for energy policy-making. A few examples are presented, and it is argued that scenarios should basically be addressed on the basis of storylines. Storylines do require a set of specific parameters, and in this case the choice was made to use the various roles played by stakeholders for intervening in markets and in the world order. This choice is argued on the basis of the global interrelations that are currently influencing resource policies in general and energy in particular. Market efficiency, climate change, poverty issues, geopolitics and global coordination mechanisms are considered, leading to the two policy dimensions of 'nationalism' versus 'globalism' and 'heavy' versus 'light' government as the axes for the scenarios and storylines. This paper develops four storylines that are conceivable and inherently consistent. They are labelled with names that refer not only to their content, but also to the political and societal climate prevailing in the region. The first, 'l'Europe des

Effective photoswitchable europium sulfide nanocrystals with gold nanoparticles using dithiol (DDT: 1,10-decanedithiol) joint molecules, EuS-Au nanosystems, are demonstrated. The TEM image indicates the formation of EuS-Au nanosystems composed of cube-shaped EuS nanocrystals and spherical Au nanoparticles. Under visible-light irradiation, a drastic change of absorption band of EuS-Au nanosystems at around 600 nm was observed. The Faraday effects of EuS-Au nanosystems were estimated using magnetic circular dichroism (MCD) measurements. The effective change of the MCD spectra of EuS-Au nanosystems under visible-light irradiation was successfully observed at around 670 nm for the first time. The effective reversible changes in MCD spectra with the alternative irradiation cycles of visible light (>440 nm) and dark are also presented. The decrease rate of rotation angle at 670 nm of EuS-Au nanosystems is larger than that of absorbance. These results indicate that the effective change of MCD spectra of EuS-Au nanosystems would be dominated not only by a drastic change of absorption band related to enhanced LSPR of Au nanoparticles but also by specific interaction between EuS and Au in nanosystem under irradiation.

Highlights: • Eu incorporated ZnO thin films were grown by sol–gel spin coating. • The influence of Eu contribution on features of ZnO was investigated. • Al/ZnO:Eu/p-Si heterojunction diodes were also fabricated. • The diode parameters were calculated from I–V measurements. - Abstract: In present work, the pure and europium (Eu) incorporated zinc oxide (ZnO) thin films were deposited with sol-gel spin coating by using zinc acetate dehydrate and Eu (III) chloride salts. The coated films were examined by means of XRD, AFM and UV/VIS spectrophotometer. The ZnO hexagonal wurtzite nanoparticles with (002) preferential direction were observed for all films. The values of crystallite size, micro-strain and surface roughness continuously increased from 21 nm, 1.10 × 10{sup −3} and 2.43 nm to the values of 35.56 nm, 1.98 × 10{sup −3} and 28.99 nm with Eu doping, respectively. The optical band gap value of the pure ZnO initially increased from 3.296 eV to 3.328 eV with Eu doping up to 2 at.% doping level, then it started to decrease with more Eu content. The electrical features of Al/n-ZnO:Eu/p-Si heterojunction diodes were inquired by current-voltage (I–V) measurements at the room temperature.

The paradox of EU enlargement and member states' policies: Dilemmas and challenges: The case of Portugal

Directory of Open Access Journals (Sweden)

Neves Santos Miguel

2016-01-01

Full Text Available The paper addresses the issue of EU enlargement with its dual nature: of an intra-EU process, related to the consolidation of a democratic-peace based on collective security, and an external process, involving EU foreign policy and impact on relations with other major global players. Although enlargement is a multidimensional process that combines different perspectives - candidate countries' enlargement politics, member states' politics/policy, EU enlargement politics and external global impact - the paper focuses on Member States policies towards enlargement by looking at the case of Portugal, in particular in relation with the Big Bang Eastern enlargement, and aims at explaining the paradox of Portugal's strong political support to enlargement while it was one of the main potential losers in terms of economic interests. A 'foreign policy analysis' framework is adopted in order to understand the process of decision-making and the interaction between the domestic and the EU levels. The argument put forward is that an exclusive constructivist approach does not provide a satisfactory explanation, as there was also rationalist-interest logic at play. The Portuguese policy towards enlargement was determined not only by the 'solidaritysimilarity' logic, dominant in the formal political discourse but also by the consideration of long-term interests in the EU related to the preservation of the strategic alliance with Germany. The overall systemic impact of enlargement tends to weaken the EU as it presents a major paradox functioning as a double-edged sword. While it has a positive impact by contributing to the enhancement of the EU international profile as it grows in size raising expectations about its potential global role, it also leads to greater heterogeneity, undermining the EU cohesion and its ability to act together with a single voice becoming a robust global player, thus frustrating the expectations raised in the first place.

New reddish-orange and greenish-yellow light emitting phosphors: Eu3+ and Tb3+/Eu3+ in sodium germanate glass

A spectroscopic analysis of sodium germanate glasses activated with Eu 3+ , Tb 3+ and Eu 3+ /Tb 3+ is performed from their photoluminescence spectra and decay times. In the Eu 3+ -singly doped glass reddish-orange light emission, with x=0.64 and y=0.35 CIE1931 chromaticity coordinates, is obtained upon Eu 3+ excitation at 393 nm. Such chromaticity coordinates are close to those (0.67, 0.33) proposed by the National Television Standard Committee for the red phosphor. When the sodium germanate glass is co-doped with Tb 3+ and Eu 3+ greenish-yellow light emission, with (0.41, 0.46) CIE1931 chromaticity coordinates, is obtained upon Tb 3+ excitation at 344 nm. Such greenish-yellow luminescence is due mainly to the terbium 5 D 4 → 7 F 6,5 and europium 5 D 0 → 7 F 1,2 emissions, Eu 3+ being sensitized by Tb 3+ through a non-radiative energy transfer. The non-radiative nature of this energy transfer is inferred from the increase in the decay rate of the Tb 3+ emission when the glass is co-doped with Eu 3+ . From an analysis of the Tb 3+ emission decay time curves it is inferred that such energy transfer might take place between Tb 3+ and Eu 3+ clusters through a short-range interaction mechanism. - Highlights: • Sodium germanate glasses are optically activated with Eu 3+ (GNE) and Tb 3+ /Eu 3+ (GNTE). • Reddish-orange light (0.64, 0.35) is generated by GNE pumped with 393 nm light. • Greenish-yellow light (0.41, 0.46) is generated by GNTE pumped with 344 nm light. • Non-radiative energy transfer Tb 3+ →Eu 3+ takes place in GNTE

EU trade in the time of financial crisis

Directory of Open Access Journals (Sweden)

Fojtíková, L.

2010-12-01

Full Text Available The paper is focused on the European Union (EU trade and trade policy in the time of global financial and economic crisis. The analysis of the EU exports and imports points out that the financial crisis has had a negative impact on the intra as well as on the extra-EU trade in the period 2007-2009, but differences among the EU member states have existed. Although the EU tries to support trade development in the world and remove barriers to trade, some protectionist tendencies were recorded in the time of the economic crisis. The last part of the paper gives emphasis to the EU trade policy and some trade measures which have been taken in the EU and its member states to support trade development or vice versa, to protect domestic industries. The results of the analysis show that, although some protectionist tendencies have been recorded both in extra and intra-EU trade, trade relations which are provided among member states are of significant importance all the time.

The EU internal market - a stake or a tool in European-Russian gas relations. The case of new member states gas

International Nuclear Information System (INIS)

Loskot-Stachota, Agata; Ramsay, William C.

2011-06-01

Since 2010 we have observed a new quality in EU energy policy. It is related to the European Commission's more or less direct engagement in the bilateral gas relations of a part of the new member states - Poland, Bulgaria and Lithuania - with Russia. Although the long term outcome of this activity of the EC is as yet unclear it seems to be important for several reasons. Firstly it might increase the possibilities of the enforcement of the EU's directives liberalising the internal gas market and specifically their implementation in individual gas agreements with suppliers from third countries (Gazprom). The consistency and determination of the EC in this field may be decisive for the future direction and depth of the liberalization of the EU gas market. Furthermore, present developments may lead to an increase in EU and specifically EC competence in the field of energy policy, especially its external dimension. So what lessons can we draw from recent Commission activities on the following issues: - Implementing EU gas market 2. and 3. liberalization packages and their main provisions - EU energy policy and its external dimension - recent developments and the EU's role - EU-Russia gas relations - where Russian and EU interests diverge.

EU import restrictions on genetically modified feeds: impacts on Spanish, EU and global livestock sectors

Energy Technology Data Exchange (ETDEWEB)

Philippidis, G.

2010-07-01

Over the last decade, much controversy has surrounded the usage of genetically modified organism (GMO) technology in commercial agriculture. More specifically, it is feared that GMOs may introduce new allergens into the food chain or contribute to antibiotic resistance. At the current time, the European Union (EU) adopts a zero tolerance policy toward non-approved GMO imports, whilst the approval process has not kept pace with the proliferation of new GMO varieties. In the EU livestock sectors, this apparent mis-match threatens to interrupt supplies of high protein feed inputs (e.g., soy meal) from countries with more relaxed regulations regarding GMOs. Employing a well known multi-region computable general equilibrium framework, this study quantitatively assesses the impact of a hypothetical EU import ban on unapproved GMO varieties of soybean and maize imports on livestock, meat and dairy sectors. The model code is heavily modified to improve the characterisation of the agricultural sectors and land usage, whilst a realistic baseline is employed to update the global database to 2008, the year the hypothetical ban is implemented. In the worst case scenario, there are significant competitive losses in EU livestock, meat and dairy sectors. In Spain, the negative impacts are particularly pronounced given the importance of pig production in agriculture. In contrast, all non-EU regions trade balances improve, with notable trade gains in the USA and Brazil. To conclude, the EU must urgently find a long term strategy for GMOs if it is to reconcile political expediency with pragmatic economic concerns. (Author) 21 refs.

Sectoral agreements and competitive distortions - a Swedish perspective; Effects of EU Emissions Trading System for European industry

Zetterberg, Lars; Holmgren, Kristina

2009-03-15

The objectives of this study are to: Give an overview of the current discussion concerning competition distortion in relation to climate policy; Describe results from some studies estimating the actual competition situation for selected activities; Describe what sector agreement models are suggested/ discussed by EU; Describe what sectors are most interesting to target with a sector agreement from a Swedish point of view; Analyse what parameters are important for reducing competition distortion for Swedish Industry. Two studies, for the United Kingdom and Germany, have recently assessed the potential cost impact for different industrial sectors of CO{sub 2}-prices due to the EU ETS. The sectors with high potential impact, with a maximum value at stake larger than 10%, are in the United Kingdom Lime and cement, Basic iron and steel, Starches, Refined petroleum, Fertilizers and Nitrogen compounds and Aluminium. In Germany: Cement and lime, Fertilizers and nitrogen compounds, Basic iron and steel, Aluminium, Paper and board, Other basic inorganic compounds and Coke, refined petroleum and nuclear fuels. Ex-ante studies of the impacts of competitiveness and carbon leakage due to the EU ETS fail to find actual impacts. However, that does not mean that there will be no impact in the future, which hold changes both in the EU ETS (method for allowance allocation, allowance prices etc) and possibly also other important circumstances. In this study, based on official Swedish statistics, the maximum value a stake has been calculated for 52 Swedish sectors. Seven sectors have a maximum value a stake of more than 4%: Coke and refined petroleum (21%), Pulp and paper (11%), Basic metals (10%), Non-metallic mineral (9%), Metal ore mines (6%), Air transport (5%) and Electricity, gas and heat (4%). If Air transport and Electricity, gas and heat are omitted, the five remaining sectors account for 22% of Sweden's carbon emissions. In late 2008, the EU proposed three types of

Economic, environmental and international trade effects of the EU Directive on energy tax harmonization

Kohlhaas, Michael; Schumacher, Katja; Diekmann, Jochen; Schumacher, Dieter; Carmes, Martin

2005-01-01

In October 2003, the European Union introduced a Directive, which widens the scope of the EU's minimum taxation system from mineral oils to all energy products including coal, natural gas and electricity. It aims at reducing distortions that currently exist between Member States as well as between energy products. In addition, it increases previous minimum tax rates and thus the incentive to use energy more efficiently. The Directive will lead to changes in the energy tax schemes in a number of countries, in particular some southern Member Countries (Greece, Spain, Portugal) and most of the new Member States. In this paper, we analyze the effects of the EU energy tax harmonization with GTAP-E, a computable general equilibrium model. Particular focus is placed on the Eastern European countries, which became new members of the EU in May 2004. We investigate the effects of the tax harmonization on overall economic growth and sectoral development. Special attention is paid to international trade in order to analyze if competitiveness concerns, which have been forwarded in the context of energy taxation are valid. Furthermore, the effect on energy consumption and emissions and thus the contribution to the EU's climate change targets is analyzed

We report the effect of replacing Cu by Pd in RCu 5 (R=Pr, Nd, Sm and Eu). The parent RCu 5 compounds crystallize in the hexagonal CaCu 5 -type structure. The hexagonal symmetry is retained in PrCu 4 Pd and EuCu 5-x Pd x (x=1 and 2) but the crystal structure changes to cubic AuBe 5 -type in PrCu 3 Pd 2 , NdCu 5-x Pd x (x=1 and 2) and SmCu 4 Pd. Substitution with Pd leads to lattice expansion and modifies the magnetic behavior. While PrCu 5 is known to be a van-Vleck paramagnet with a singlet ground state, PrCu 4 Pd and PrCu 3 Pd 2 show ferromagnetic-like behavior at low temperatures. SmCu 4 Pd orders ferromagnetically near 28 K in contrast to the antiferromagnetic nature of the parent SmCu 5 . The divalent nature of the Eu ions in EuCu 5 is retained in the ternary alloys, but the Curie temperature is reduced from 57 to 24.5 and 14.5 K in EuCu 4 Pd and EuCu 3 Pd 2 , respectively, inferred from the location of peak in the heat capacity of these two compounds. The magnetic hyperfine field at the Eu nucleus measured with 151 Eu Moessbauer spectroscopy in the ternary Eu-alloys is comparable to that in EuCu 5 . The magnetic behavior of NdCu 4 Pd is similar to that reported in NdCu 5 . The zero-field-cooled, low-field magnetization of NdCu 3 Pd 2 shows a region of diamagnetic behavior roughly between 21 and 4 K, but the field-cooled response is positive.

GENERAL OVERWIEV ON EU ECONOMY

Full Text Available The impact of the international economic crisis on new EU member states has proven to be more severe than the first estimates of the economic analysts. The situation is different for each Member State, the nature and the dimension of the challenges faced are not identical, and the pace of reform is not the same. The economic crisis has prompted intense and sustained action by the EU's national governments, the European Central Bank and the Commission. All have been working closely together to support growth and employment, ensure financial stability, and put in place a better governance system for the future. Sustainable development in the future is the common responsibility of all Member States and EU institutions, because our economies are closely interlinked, and the EU economic governance now reconfigured to provide more effective responses at the policy level, to give a good reaction to the present and the future challenges.

EuCARD final project report

After four years of activity, EuCARD has most of its objectives fulfilled, with some new objectives added and a few others on excellent tracks while requiring additional time. The management has been active in reinforcing the collaborative links between partners and projects, contributing to the preparation of FP7-EuCARD2, initiating FP7-HiLumi-LHC Design Study, to favour sustained collaborations beyond EuCARD. An out-of-contract network has been successfully launched on laser plasma acceleration, to combine forces between accelerator, laser and plasma communities. Communication and dissemination activities have led to two highlights: Accelerating News, an accelerator R&D newsletter initiated by EuCARD and now common to all FP7 accelerator projects (over 1000 subscribers) and a series of monographs on accelerator sciences that is progressively finding its public. The scientific networks have more than fulfilled their initial objectives: roadmaps are defined for neutrino facilities, submitted to the Europe...

Global Europe and the EU's Raw Materials Initiative are designed to bolster the EU's economic position - whatever the cost - in the face of fierce global competition for both markets and resources, especially from emerging economies such as China and India. The EU also fears losing trade to the US, which has already secured trade and investment concessions from countries in the Western hemisphere, through the Dominican Republic-Central American Free Trade Agreement (DR-CAFTA) and other bilateral trade agreements.

Pyrochlore-type Eu{sub 2}Ta{sub 2}(O,N){sub 7+δ} phases were prepared by reaction of ammonia with an amorphous europium tantalum oxide precursor. {sup 151}Eu Moessbauer and EPR spectroscopy as well as magnetic susceptibility measurements point to the presence of exclusively Eu{sup 3+}. For phase-pure samples (X-ray powder diffraction), the nitrogen content varies between 1.0 and 1.8 wt %, leading to compositions in the range Eu{sub 2}Ta{sub 2}O{sub 7.1}N{sub 0.6} - Eu{sub 2}Ta{sub 2}O{sub 6.5}N{sub 1.0}. Pyrochlore-type phases are structurally derived from the fluorite type with 1/8 of the anions missing, resulting in an ideal composition A{sub 2}B{sub 2}X{sub 7}. In Eu{sub 2}Ta{sub 2}(O,N){sub 7+δ} the excess anions partly occupy these vacancies. The prepared phases are colorless with a direct optical bandgap of 4.3 eV and they show the typical Van Vleck paramagnetic behavior known for trivalent Eu atoms.

Resonant TMR inversion in LiF/EuS based spin-filter tunnel junctions

Directory of Open Access Journals (Sweden)

Fen Liu

2016-08-01

Full Text Available Resonant tunneling can lead to inverse tunnel magnetoresistance when impurity levels rather than direct tunneling dominate the transport process. We fabricated hybrid magnetic tunnel junctions of CoFe/LiF/EuS/Ti, with an epitaxial LiF energy barrier joined with a polycrystalline EuS spin-filter barrier. Due to the water solubility of LiF, the devices were fully packaged in situ. The devices showed sizeable positive TMR up to 16% at low bias voltages but clearly inverted TMR at higher bias voltages. The TMR inversion depends sensitively on the thickness of LiF, and the tendency of inversion disappears when LiF gets thick enough and recovers its intrinsic properties.

Blue emission in photoluminescence spectra of the red phosphor CaAlSiN3:Eu2+ at low Eu2+ concentration

Science.gov (United States)

Suda, Yoriko; Kamigaki, Yoshiaki; Yamamoto, Hajime

2018-04-01

In red phosphor CaAlSiN3:Eu2+, unintentional blue emission occurs with increasing intensity at low Eu2+ concentrations and also at low measurement temperatures. Time-resolved photoluminescence measurements were used to confirm the decrease in red emission and increase in blue emission with the decreasing Eu2+ concentration. The peak timing of blue emission occurred faster than that of red emission, and long lasting luminescence of red emission was observed as well as that of blue emission. The Eu2+ concentration dependences of the red and blue emissions were similar to those of the g values 4.75 (Eu2+) and 2.0025 (nitrogen vacancies), respectively, which were observed from electron spin resonance (ESR) measurements. The origin of the blue emission is proposed to be nitrogen vacancy defects, which had about the same ESR signal intensity as that of Eu2+ ions in CaAlSiN3:Eu2+ containing 0.01 at. % Eu2+. The possibility of red emission also arising from excited electron tunneling or thermal pathways via nitrogen vacancies is discussed. Long lasting red emission was observed, which is proposed to involve trapped electrons remaining at nitrogen vacancies, yielding blue emission and inducing red emission from Eu2+ ions.

Multi-level lobbying in the EU: The case of the Renewables Directive and the German energy industry

Energy Technology Data Exchange (ETDEWEB)

Ydersbond, Inga Margrete

2012-11-01

This study examines the lobbying strategies employed by the interest organizations of Germany's energy industries in the process leading up to the EU's Renewable Energy Directive. How did they lobby, and what does this reveal about their perceptions of power relations in the EU? This report focuses on the most controversial part of the Directive: legal prescriptions for support mechanisms to increase the production of renewable energy in Europe. The utilities and the renewables industries disagreed deeply, with the utilities industry favouring an EU-wide green certificate scheme, while the renewables industry pressed for national feed-in tariffs. Nine interest organizations representing these sectors, five German and four at the EU level, serve as cases in this study. Expectations as to lobbying behaviour based on the two theories/theory perspectives of liberal intergovernmentalism (LI) and multi-level governance (MLG) are formulated and tested in a most-likely case design. Result: observations are better described by the MLG perspective than by LI.(auth)

In this paper, phosphors of LuF{sub 3}:Eu{sup 3+}/Tb{sup 3+} have been successfully synthesized with small chelator ethylenediaminetetra acetic acid (EDTA) or amphiphilic polymer (polyethylene glycol, PEG-1000) as templates via a hydrothermal method. X-ray powder diffraction (XRD), scanning electronic microscope (SEM), and photo-luminescent spectra techniques (PL) were used to characterize the as-prepared samples. XRD patterns showed that well crystallized lanthanide fluorides with hexagonal phase were achieved. SEM images revealed that different regular microstructures were achieved. The photo-luminescent properties of LuF{sub 3}:Eu{sup 3+} demonstrated that there are significant energy transfers from fluorides to Eu{sup 3+}. The results presented that EDTA as the template will lead to the highest emission intensities. -- Highlights: • Various templates were used to synthesize LuF{sub 3}:Eu{sup 3+}/Tb{sup 3+}. • All the phosphors were red or green emissive. • Different morphologies were acquired and controllable.

Fighting windmills? EU industrial interest and global climate negotiations

International Nuclear Information System (INIS)

Steiner Brand, U.; Tinggaard Svendsen, G.

2003-01-01

Why has the EU been so eager to continue the climate negotiations? Can it be solely attributed to the EU feeling morally obliged to be the main initiator of continued progress on the climate change negotiations, or can industrial interests in the EU, at least partly, explain the behaviour of the EU? We suggest that the EU has a rational economic interest in forcing the technological development of renewable energy sources to get a fast-mover advantage, which will only pay if a sufficient number of countries implement sufficiently stringent GHG reductions. The Kyoto Protocol, which imposes binding reductions on 38 OECD countries, implies that, as a first-mover, the EU will be to sell the necessary new renewable technologies, most prominently wind mills, to other countries, when they ratify and implement the Kyoto target levels. In the latest EU proposal made in Johannesburg, the EU pushed for setting a target of 15% of all energy to come from sources such as windmills, solar panels and waves by 2015. Such a target would further the EU's interests globally, and could explain, in economic terms, why the EU eagerly promotes GHG trade at a global level whereas the US has left the Kyoto agreement to save the import costs of buying the EU's renewable systems.

Full Text Available JEAN d'Outremeuse fut et reste le plus populaire des vieux auteurs qui ont écrit l'histoire de l'ancienne principauté de Liège. Cette notoriété, il la doit sans doute à l'usage de la langue vulgaire -un français teinté de wallon- et aussi à l'extraordinaire profusion de détails pitttoresques qui émaillent ses narrations, où vingt générations d'érudits, de littérateurs et d'échotiers du passé ont puisé leur inspiration. Pourtant, la critique historique de notre siècle n'a eu aucune peine à démontrer que pareil ascendant n'était pas mérité, puisque Jean d'Outremeuse avait bel et bien recopié d'autres récits ou inventé de toutes pièces la matière qu'il n'avait pas trouvée dans des sources antérieures. De sorte que, à quelques nuances près, l'admiration sans bornes qu'on lui vouait jadis à désormais cédé la place au scepticisme, voire au dénigrement systématique à son égard.

Succession of States in the EU

Directory of Open Access Journals (Sweden)

Mario Martini

2014-09-01

Full Text Available A specter is haunting Europe – the specter of separatism. Scotland, Catalonia, Flanders, South Tyrol – all these regions have separatist movements pursuing independence from their current National State. The breakup of an EU Member State no longer seems impossible. To date, it is unclear what impact this would have on the EU membership of the new entities (with consequences for the character of citizenship, voting rights in the council, number of MEPs etc. that emerge from the old States. The common rules of Public International Law governing the succession of States are insufficient in the case of a succession of States in the EU. Although the Treaties do not provide for such a situation and the past 60 years of European history offer only a few and not really persuasive precedents, the nature of the EU as a joint association of sovereign States (“Staatenverbund” demands a special approach: A separated State will neither be automatically excluded from the EU nor will it automatically become a new Member State.

Energy transfer mechanism in CsI:Eu crystal

2014-01-01

This paper studies the scintillation process in CsI:Eu crystal exposed to the pulse electron irradiation (E=0.25 MeV, t 1/2 =15 ns and W=0.003 J/cm 2 ). It has been proved that the energy transfer from the lattice to Eu 2+ ions in CsI:Eu occurs through the re-absorption of STE emission. The proposed model rests on the following experimental facts: (1) the activator emission at 2.68 eV rises gradually after the decay of the excitation pulse even at temperature lower than 90 K when V k centers are immobile; (2) the rise time of 2.68 eV emission and the decay time of STE emission have the same temperature dependences at T=78–300 K; (3) the excitation spectrum of 2.68 eV emission overlaps the emission spectrum of STE. -- Highlights: • The scintillation process in CsI:Eu was studied under pulsed electron irradiation. • A model of the energy transfer from the lattice to Eu 2+ ions in CsI:Eu was proposed. • Eu 2+ ions in CsI:Eu reabsorb the π-emission of self-trapped excitons

The EU electricity production structure requires a differentiated energy policy; Die Stromerzeugungsstruktur der EU erfordert eine differenzierte Energiepolitik

For the electricity production of the EU there are differentiated structures which are based on different natural conditions, political decisions and investments of past decades. It has long been struggled committed to the ''one and correct'' energy policy. But precisely because of the differences in the individual countries, a unified energy and climate policy for the EU is not the right way. Diversity is a strength, which quite the EU Commission considered. Increased understanding of the specifics in other countries should just apply the German politics and the public that all too often judges from their own perspective. [German] Bei der Stromerzeugung in der EU bestehen differenzierte Strukturen, die auf unterschiedlichen natuerlichen Gegebenheiten, politischen Entscheidungen und Investitionen vergangener Jahrzehnte beruhen. Seit langem wird engagiert um die ''eine und richtige'' Energiepolitik gerungen. Doch gerade wegen der Unterschiede in den einzelnen Laendern kann eine vereinheitlichte Energie- und Klimapolitik fuer die EU nicht der richtige Weg sein. Vielfalt ist eine Staerke, was die EU-Kommission durchaus beruecksichtigt. Mehr Verstaendnis fuer die Spezifika in anderen Laendern sollte daher gerade die deutsche Politik und Oeffentlichkeit aufbringen, die allzu oft aus eigener Perspektive heraus urteilt.
