欧盟的环境与资源保护——法律、政策和行动

欧盟是各个成员国之间为消除贸易的环境障碍,首先在环境保护的共同标准上进行协商和签订条约,所以乃是以环境为中心,覆盖资源保护问题。现在欧盟已成为超国家的地区主权的实体。欧盟的环境保护局已经成了一个大袋子,把环境保护、资源保护、自然保护甚至与工农业生产有关的问题都包括了进去。它的好处就是有利统一协调。欧盟的环境保护在４０多年中,走过了从各成员国自行负责到形成共同的法律和行动,从工业环境为主到全面生态环境保护,从治理污染到主动预防,从国家到区域到全球行动,在环境保护行动中欧盟将变得更为活跃和日益重要     

Modelling scenarios towards a sustainable use of natural resources in Europe

Issues related to the unsustainable use of natural resources are currently high on the policy agenda both in Europe and in other world regions. A large number of studies assessed past developments of material use and resource productivities. However, little effort has so far been devoted to forecasting future patterns of natural resource use and to provide ex-ante assessments of environmental and economic effects of different resource policies. This paper presents results from the international research project “MOSUS” (Modelling opportunities and limits for restructuring Europe towards sustainability), which was designed to fill some of these research gaps. In this project, a global economy–energy model system was extended by a worldwide database on material inputs, in order to run three scenarios for European development up to the year 2020: a baseline scenario without additional policy intervention and two so-called “sustainability scenarios”, simulating the implementation of six packages of policy measures geared towards decoupling economic activity from material and energy throughput. These measures included, amongst others, taxes on CO₂ emissions and transport, measures to increase metal recycling rates, and a consulting programme to raise material productivity of industrial production. This paper presents the evaluation of the three scenarios with regard to the extraction of natural resources on the European and global level. In the baseline scenario, used domestic extraction within the EU remains roughly constant until 2020, while unused domestic extraction decreases (particularly overburden from mining activities). The stabilisation of domestic extraction, however, is accompanied by growing imports of material intensive products. This indicates that the material requirements of the European economy will increasingly be met through imports from other world regions, causing shifts of environmental pressures related to material extraction and processing away from Europe towards resource-rich countries. The implementation of the six sustainability policy measures applied in the sustainability scenarios results in a slight absolute reduction of domestic extraction in all European countries and significantly increased resource productivities. The results suggest that policy instruments aimed at raising eco-efficiency on the micro level can be conducive to economic growth. To limit rebound effects on the macro level, these instruments must, however, be accompanied by other policies influencing the prices of energy and materials. With regard to global resource use trends, the baseline scenario forecasts a significant growth of resource extraction, particularly in developing countries, reflecting the growing demand for natural resources of emerging economies such as China and India.     

Multi-scale scenarios of spatial-temporal dynamics in the European livestock sector

The European livestock sector has changed rapidly in the recent past and further changes are expected in the near future due to reforms in the European Common Agricultural Policy (CAP), increasing environmental concerns and changing consumer awareness. We developed a multi-scale modeling approach for exploring spatial and temporal dynamics of livestock distribution by accounting for drivers at different spatial scales. Such approach can provide a basis for environmental impact assessments of livestock farming at broad spatial scales. Assessment of change in both quantity and location was made for six livestock types. Four contrasting scenarios were applied ranging from globalization to regionalization, as well as from low regulation levels and dominance of market forces towards a higher degree of governmental regulation. National level livestock numbers as calculated by a macro-economic model were spatially distributed at the landscape scale according to the scenario assumptions considering biophysical, socio-economic, and political forces. Results indicate for most of the old European Union (EU) member countries a decrease in livestock numbers. In the new EU member countries sheep, goats and pigs are expected to decline while beef cattle and poultry are expected to grow. Livestock densities are expected to increase both within and outside current livestock hotspot regions in absence of environmental legislations. Environmental pressure as result of high livestock densities may, however, also remain in regulated scenarios where environmental policies are implemented and income support remains stable over time due to path dependencies in the livestock sector. But contrary to the non-regulated scenario it is less likely that new areas with high risk of negative environmental impacts due to livestock farming will develop.

Material flow accounting in an Irish city-region 1992–2002

This paper aims to measure raw material inputs and waste flows in an Irish city-region in order to analyse (i) whether there was absolute dematerialisation in the particular case study over the period 1992–2002 and (ii) whether material consumption and waste generation were decoupled from economic growth and increases in disposable income over the same period. It was found that the selected material flow indicators showed no evidence of absolute dematerialisation over the given study period, although more recent evidence at the national level suggests that a decline in construction activity and extraction of non-metallic minerals has resulted in an absolute reduction in material consumption and it is likely that this will be mirrored at the system boundary level.It was found that Domestic Material Consumption (DMC) per capita and Direct Material Input (DMI) per capita increased at a faster rate than Domestic Processed Output (DPO) per capita and Direct Material Output (DMO) per capita between 1992 and 2002, which indicates relative decoupling of consumption from waste generation. In addition, it was found that there was relative decoupling of consumption and waste generation from disposable income growth over the study period. Finally, it was found that average DMC and DMI figures for the selected case study were lower than the national averages but broadly similar to results for other city-regions in the European Union (EU). On a methodological note, it was concluded that material flow accounting (MFA) for city-regions in Ireland is constrained due to a lack of disaggregated data for material flows, with the exception of local waste data, and it is recommended that bottom-up analysis should be used to complement disaggregated top-down data.     

Climate change policy and water resources in the EU and Spain. A closer look into the Water Framework Directive

Climate change effects are becoming evident worldwide, with serious regional and local impacts. The European Union (EU) has launched and developed initiatives and policies that scratch the surface of water resources impacts. This article presents an introduction of the existing environmental policy and more concisely in the areas of climate change and the interactions with water resources. It also addresses main management tools, and plans linked to policies, recent updates on the Science–Policy Interface, highlighting major results from research and development projects. Establishing appropriate policies to tackle climate change impacts on water is essential given the cross-sectorial and flowing nature and the importance of water in all environmental, social and economic sectors. There are still some pending reviews and updates in the current EU policy and its implementation, as well as at the national level in Spain. This article identifies existing gaps, and provides recommendations on how and where reforms could take place and be applied by decision makers in the water policy sector.     

The challenge of sustainability: incentives for brownfield regeneration in Europe

Brownfields are often not economically competitive for regeneration compared with greenfield sites without public intervention. The economic, environmental and social barriers present at the site frequently hinder returning brownfields to beneficial use. The European Union and its member states provide different public incentives to make brownfield regeneration more attractive but rarely consider their sustainability. Deciding how to regenerate brownfields should involve more than redeveloping the site to meet regulations or to meet a predetermined site use. Member states, policy makers, land owners and developers need to understand all aspects of brownfield regeneration and how sustainability issues need to be paramount in choosing alternative site uses. This paper presents the existing incentives on a European Union level, in Germany, the UK, and France; it discusses the effects and gaps; and makes suggestions for more effective instruments for the promotion of sustainable brownfield regeneration.     

Financial adaptation to disaster risk in the European Union

Increasing losses from weather related extreme events coupled with limited coping capacity suggest a need for strong adaptation commitments, of which public sector responses to adjustments to actual and expected climate stimuli are key. The European Commission has started to address this need in the emerging European Union (EU) climate adaptation strategy; yet, a specific rationale for adaptation interventions has not clearly been identified, and the economic case for adaptation to extremes remains vague. Basing the diagnosis on economic welfare theory and an empirical analysis of the current EU and member states’ roles in managing disaster risk, we discuss how and where the public sector may intervene for managing climate variability and change. We restrict our analysis to financial disaster management, a domain of adaptation intervention, which is of key concern for the EU adaptation strategy. We analyse three areas of public sector interventions, supporting national insurance systems, providing compensation to the affected post event as well as intergovernmental loss sharing through the EU solidarity fund, according to the three government functions of allocation, distribution, and stabilization suggested by welfare theory, and suggest room for improvement.     

Twenty five years of industrial development: a study of resource use rates and macro-efficiency indicators for five Asian countries

Economic and population growth in Asia over the last three decades has been unprecedented. While conventional economic indicators have been increasing consistently, indicators of resource and environmental quality have been deteriorating, raising questions about the implications of future growth. Economic growth in the future is considered to be contingent on ensuring a more efficient use of natural resources, while simultaneously striving to reduce environmental impacts. We examine time trends of three efficiency indicators; agricultural efficiency, energy efficiency of economic production and carbon efficiency of energy use, for the five most populous countries in Asia in order to assess whether industrial development has lead to increased resource use efficiency and an associated reduction in total resource use and environmental impacts. Our results indicate that agricultural efficiency has decreased in all five countries. Results are mixed for energy and carbon efficiencies. Where increases in energy and carbon efficiency have occurred, they have been completely overwhelmed by absolute increases in energy use and carbon emissions caused by increases in the scale of economic activity. Based on this analysis, we study the potential for further improvements and policy implications for future food supply, energy consumption and carbon emissions in the region.     

Effects of bioenergy policies and targets on European wetland restoration options

The EU is committed to combat climate change and to increase security of its energy supply. Bioenergy from forestry and agriculture plays a key role for both. Concurrently, the EU agreed to halt the loss of biodiversity within its member states. To fulfil the biodiversity target more nature conservation and restoration sites need to be designated. There are arising concerns that an increased cultivation of bioenergy crops will decrease the land available for nature reserves and for “traditional” agriculture and forestry. To assess the role of bioenergy in light of possible negative impacts on ecosystems, the European Forest and Agricultural Sector Optimization Model (EUFASOM) assesses simultaneously economic and environmental aspects of land use. This study contributes to the assessment by analyzing the effect of bioenergy production on European wetland allocations by incorporating the spatial wetland distribution model SWEDI into EUFASOM. Results show that bioenergy targets increase land competition and thus marginal costs of wetland preservation but also of food prices. The designation of national wetland conservation targets, on the other hand, stimulates land use intensification in countries without these targets and here only a transfer of environmental stresses takes place. The model is able to illustrate regional differences of results.     

Policy,legislative and institutional assessments for integrated river basin management in Turkey

The rapidly growing population, increased urbanization, and intensive industrial and agricultural activities cause degradation and pollution of natural resources, soil erosion, and changes in hydrologic regimes in all over the world. To overcome these situations, it is necessary to develop an effective and holistic management methodology, called Integrated River Basin Management (IRBM). It is an internationally accepted administrative tool.IRBM is also one of the implementation requirements of the European Commission Water Framework Directive (WFD, 2000/60/EC) for European Union (EU) member states and candidate countries. Turkey, as an EU candidate country, already has started and continues to work toward adaptation of the WFD. Since the early 2000s, river basin studies have been undertaken to help integrate the WFD into Turkish legislation. Although Turkey has a strong legislative background, there are many challenges in this transition period because of several big river basins, the lack of environmental infrastructure, and the cost of carrying out the WFD.This paper analyses the political, legislative, and institutional advances of the implementation of IRBM in Turkey. Before the assessments of the new Turkish legislation developments and new basin institutions, the general principles of IRBM are explained. Finally, some recommendations for improving the effectiveness of the new basin organizations and water legislation are presented.     

Drivers for the use of materials across countries

This paper analyses drivers for resource use and material productivity across countries. This is not only relevant in light of soaring raw material prices but also because EU policies, such as the ‘Thematic Strategy on the Sustainable Use of Natural Resources’ (COM [2005] 670), the EU Raw Materials Initiative (COM [2008] 699) and various similar policies internationally, seek to better manage materials along their life-cycle and across economies. In order to better understand the system dynamics of material use, our paper applies methodologies of material flow analysis and regression analysis to identify the major drivers for resource use and decoupling from GDP. Drivers are understood as those factors that exert influence on human activities to use resources. A panel data set is taken for the European Union for the years 1980-2000 (EU-15) and 1992-2000 (EU-25). The main drivers of resource use were found to be energy efficiency, new dwellings and roads construction activities. Shortcomings of the methodology are also discussed.     

Top-down approaches for sharing GHG emission reductions: uncertainties and sensitivities in the 27 European Union Member States

To reduce GHG emissions, the 27 European Union Member States committed themselves in 2007 to reduce emissions from 1990 levels by 20% by 2020. In January 2008, the EU Commission gave the first country-specific proposals to reduce emissions in sectors outside the EU emission trading system (non-ETS). In this study, we looked at several ways of sharing emission reductions in the non-ETS sector. We considered population and economic growth as significant drivers of the development of emissions. In particular, we analyzed development in GHG intensity of economies. Reduction requirements vary greatly among countries depending on the principle of effort sharing. The results of our calculations can be perceived as examples of how effort sharing between the EU Member States could look like when certain assumptions are made. Generally they illustrate the sensitivity of the results to data used, assumptions made, and method applied. The main strength of simple top-down approaches is transparency. A major weakness is a very limited ability to consider national circumstances. Political negotiations are ultimately crucial; an analysis like this provides material for negotiations and makes a contribution to solving the effort-sharing problem. As future development is partly unpredictable, implementation of some kind of subsequent adjustment could be considered during the process.     

The European Commission's sustainable consumption and production and sustainable industrial policy action plan

The promotion of sustainable consumption and production patterns is enshrined as a key objective in the renewed European Union Sustainable Development Strategy (EU SDS). Sustainable consumption and production is arguably the most challenging aspect of the EU SDS. It requires changes to the way products and services are designed, produced, used and disposed of, taking into account producer and consumer behaviours. This paper reviews the European Commission's Communication on the sustainable consumption and production and sustainable industrial policy action plan, introduced on July 16, 2008. The paper examines the priority areas identified for action, the means adopted to improve energy and environmental performance of products as well as uptake by consumers. The paper concludes that the absence of mandatory quantifiable targets and deadlines and a reliance on both cross-sectoral and multi-level relationships are likely to weaken the ability of the action plan's fundamental objective of decoupling economic growth from resource use.

Impact assessment of climate policy on Poland's power sector

This article addresses the impact of the European Union Emissions Trading System (EU ETS) on Poland’s conventional energy sector in 2008–2020 and further till 2050. Poland is a country with over 80% dependence on coal in the power sector being under political pressure of the European Union’s (EU) ambitious climate policy. The impact of the increase of the European Emission Allowance (EUA) price on fossil fuel power sector has been modelled for different scenarios. The innovation of this article consists in proposing a methodology of estimation actual costs and benefits of power stations in a country with a heavily coal-dependent power sector in the process of transition to a low-carbon economy. Strong political and economic interdependence of coal and power sector has been demonstrated as well as the impact caused by the EU ETS participation in different technology groups of power plants. It has been shown that gas-fuelled combined heat and power units are less vulnerable to the EU ETS-related costs, whereas the hard coal-fired plants may lose their profitability soon after 2020. Lignite power plants, despite their high emissivity, may longer remain in operation owing to low operational costs. Additionally, the results of long-term, up to 2050, modelling of Poland’s energy sector supported an unavoidable need of deep decarbonisation of the power sector to meet the post-Paris climate objectives. It has been concluded that investing in coal-based power capacity may lead to a carbon lock-in of the power sector. Finally, the overall costs of such a transformation have been discussed and confronted with the financial support offered by the EU. The whole consideration has been made in a wide context of changes ongoing globally in energy markets and compared with some other countries seeking transformation paths from coal. Poland’s case can serve as a lesson for all countries trying to reduce coal dependence in power generation. Reforms in the energy sector shall from the very beginning be an essential part of a sustainable transition of the whole nation’s economy. They must scale the power capacity to the future demand avoiding stranded costs. The reforms must be wide-ranging, based on a wide political consensus and not biased against the coal sector. Future energy mix and corresponding technologies shall be carefully designed, matched and should remain stable in the long-term perspective. Coal-based power capacity being near the end of its lifetime provides an economically viable option to commence a fuel switch and the following technology replacement. Real benefits and costs of the energy transition shall be fairly allocated to all stakeholders and communicated to the society. The social costs and implications in coal-dependent regions may be high, especially in the short-term perspective, but then the transformation will bring profits to the whole society.     

The globalization of the carbon market: Welfare and competitiveness effects of linking emissions trading schemes

In the light of the prevailing goal to keep global temperature increase below 2° and recent challenges to reach a global climate agreement in the near term, linking emissions trading schemes has emerged as a prominent complementing policy option. To this end, we explicitly assess (1) the macroeconomic welfare impacts and (2) the trade-based competitiveness effects of linking the European Union (EU) Emissions Trading Scheme in the year 2020. A stylized partial market analysis suggests that, independently of regional cost characteristics, the integration of emissions trading schemes (ETS) yields economic welfare gains for all participating regions. A computable general equilibrium analysis confirms these findings at the macroeconomic level: The economic efficiency losses from emissions regulation are diminished for both EU Member States and non-EU regions by linking ETS. However, the quantitative analysis suggests opposite trade-based incentives for linking up: while EU Member States improve their terms of trade by integrating with emerging ETS, non-EU linking candidates face competitiveness losses by linking. We conclude that, for non-EU regions, the attractiveness of linking ETS is a matter of priorities for economic welfare or international competitiveness. If these priorities are hierarchized in favor of welfare, the globalization of the carbon market could become a promising policy option complementing the efforts to reach a global climate agreement in 2015.
