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     

环境要素的环境收益、数量测算与受益归宿

为定量测算环境收益及其受益归宿,理解经济增长与环境保护的复杂耦合关系,匹配了中国工业企业数据库与环境统计数据库,用2011~2013年微观面板数据估计了企业治污成本函数,分介质、分行业加总得到了工业环境收益,采用受约束模型估计了其在企业利润、工资与税收间的分配.结果发现中国年度工业环境收益约9000亿元,是当年GDP和工业增加值的约2%与5%;高耗能行业占了环境收益的近70%.环境收益的最大受益方是企业职工,摄取了总额的约80%,政府是第二大获益方,进入企业利润的份额不足3%;环境收益贡献了企业工资的近25%,高耗能行业该比例达50%.环境要素的使用是增长的重要推动力,而工业的深度污染治理可能带来利益格局的不对称调整,对企业工资和就业产生重要影响,在绿色发展中应建立局部与整体、短期与长期利益的平衡机制.     

Low-carbon strategies towards 2050: Comparing ex-ante policy evaluation studies and national planning processes in Europe

The European Union (EU) is committed to reducing its greenhouse gas (GHG) emission levels by 80%–95% in 2050 compared to 1990 levels. Various approaches have been developed to secure and evaluate the progress made towards this objective. To gain insights into how EU Member States are aligning to this collective long-term objective, we systematically compare the planning and ex-ante evaluation processes for five EU countries (respectively Denmark, France, Germany, the Netherlands and the United Kingdom). The comparative analysis consists of a qualitative comparison of (1) the governance of long-term policy planning and evaluation processes, (2) the national arrangement for quantitative (model-based) ex-ante policy evaluation and (3) the national arrangement for qualitative ex-ante policy evaluation (stakeholder participation). In a second step we conduct a quantitative comparison of national model-based ex-ante evaluation studies to assess the relative differences between the considered routes and the differences across the various countries. Although the five Member States plan policies along the same EU objective, we find a high diversity in how long-term commitments are established, governed and evaluated on the national level. Model-based scenario analyses are commonly used to explore and evaluate the possible national routes towards the EU 2050 objective. However, as these processes mostly concentrate on domestic action, they pay little attention to how domestic policies are affected by, or affecting, other international activities throughout Europe. Hence, current findings suggest that cross-border collaboration and stakeholder participation could further strengthen the analytical understanding of required transformative change in Europe and subsequently lead to a more durable long-term solution over time.

Oil price scenarios and climate policy: welfare effects of including transportation in the EU emissions trading system

The stringency of policies needed to meet a climate target is influenced by uncertain oil prices because price changes cause emission changes, making the robustness of climate policy instruments important. As a result of its dependence on oil, emissions from the transport sector are particularly sensitive to oil price changes. We use a computable general equilibrium model to study the effects of including the transport sector in the EU??s emissions trading scheme under three future oil price scenarios. Our results show that there are potentially significant welfare gains from including transportation in the emissions trading scheme because the system as a whole helps absorb required changes in climate policy to meet the overall EU cap on emissions. There is, however, a cost in terms of somewhat greater permit price uncertainty.     

环境政策的综合影响评价模型系统及应用

研究和建立一套以可计算的均衡理论模型(CGE)为核心,同时与大气环境质量模型和健康影响模型(暴露-反应模型)连接,组成了环境政策综合评价模型,为综合评价环境政策产生的各类影响及其相互作用提供了一种评价方法.利用该模型系统,分析北京市采用能源环境税对北京市的大气环境、健康、经济发展和居民福利水平的影响.模型分析认为,北京市采用单一的能源环境税可以改善北京市的大气环境,但也将迟缓北京市的经济发展;如果北京市在采用能源环境税的同时进行绿色环境税收制度改革,则不但可以改善环境,而且可以促进北京市的可持续发展.     

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.     

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.     

Linking the Northeast states of the US mitigation program to the EU Emission Trading Scheme—Implications and costs

It is argued that there are at least five reasons for the Northeast states of the United States to implement a regional emission trading scheme for carbon dioxide despite the lack of federal policy regulations: goodwill, learning, political influence, risk management and competitiveness interests. Using an energy-economy model, the carbon price to bring the firms into compliance with a 10% reduction by 2020 is estimated to be 20-150 US$ per ton C. There have been discussions about linking the ongoing EU Emission Trading Schemes to the Northeast state initiative. The prime argument is that such a linkage would encourage a change of the federal US policy, which has traditionally followed action taken at the state level. Emissions trading with binding mitigation commitments could thus be demanded and accepted also on federal level. This paper demonstrates that the impact of linkage on permit prices depends on the reduction target in the European scheme: A low EU target results in a net flow of permits to the Northeast scheme, while a 40% EU reduction target results in a net flow of permits from the Northeast. Flow of permits from the Northeast state must be compensated for by the EU because the United States is not a party of the Kyoto Protocol. The EU must therefore buy permits in allowances recognized in the Kyoto regime in an amount equal to the net flow of permits from the Northeast states.

Interregional burden-sharing of greenhouse gas mitigation in the United States

Emissions trading is anattractive candidate for implementinggreenhouse gas mitigation, because it canpromote both efficiency and equity. Thispaper analyzes the interregional impacts ofalternative allocations of carbon dioxideemission permits within the U.S. Theanalysis is performed with the aid of anonlinear programming model for ten EPARegions and for six alternative permitdistribution formulas. The reason thatvarious alternatives need to be consideredis that there is no universal consensus onthe best definition of equity. Advanceknowledge of absolute and relative regionaleconomic impacts provides policy-makerswith a stronger basis for making thechoice. The analysis yields several usefulresults. First, the simulations indicatethat no matter how permits are allocated,this policy instrument can substantiallyreduce the cost of GHG mitigation for theU.S. in comparison to a system of fixedquotas for each of its regions. Interestingly, the welfare impacts ofseveral of the allocation formulas differonly slightly despite the large differencesin their philosophical underpinnings. Also, the results for some equity criteriadiffer greatly from their application inthe international domain. For example, theEgalitarian (per capita) criterion resultsin the relatively greatest cost burdenbeing incurred by one of the regions of theU.S. with the lowest per capita income.

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.     

Linking the EU emissions trading scheme: economic implications of allowance allocation and global carbon constraints

We investigate the role of domestic allowance allocation and global emissions constraints for the carbon-market impacts of linking the EU Emissions Trading Scheme (ETS) internationally. Employing a quantitative simulation model of the global carbon market, we find that the economic benefits from connecting the European ETS to emerging non-EU schemes strongly depend on the regional allowance allocation of the linking participants: In a world of moderate carbon constraints, an economically efficient regional allowance allocation induces a much stronger fall in total compliance costs than a sub-optimal (i.e. too high) domestic allocation of emissions permits. However, a more efficient (i.e. stricter) allocation shifts abatement efforts and compliance costs to energy-intensive industries which are covered by the domestic ETS. We further find that committing to ambitious global emissions reduction targets (compatible with stabilizing CO₂ concentrations at 450 ppm) induces much stronger regional abatement efforts and substantially higher compliance costs for the abating regions. In such an ambitious climate policy regime, an efficient domestic allocation of allowances is even more important from an economic perspective: Here, linking emissions trading schemes diminishes the associated compliance costs on the largest scale.

“White and Green”: Comparison of market-based instruments to promote energy efficiency

The “White and Green” Project completed under the EU SAVE Programme reviewed policies and measures to promote energy efficiency, which involved analysing the experience with instruments that are already implemented, and assessing innovative instruments that are proposed. In particular, the practicability of using “White Certificates” (energy efficiency) along the same lines as “Green Certificates” (renewable energy) was explored.Several of the policies and measures were simulated using technical–economic models of the MARKAL family. The results show that by 2020 it is possible to increase energy efficiency by 15% at no cost without taking externalities into account. If externalities are considered, an increase of 30–35% with respect to the business-as-usual scenario is justified.The wealth of information obtained through the models and analysis provides a set of recommendations for policy-makers, including: (1) the need for closer co-ordination between energy policies and environmental and climate policies; (2) the opportunity to establish more ambitious targets for energy efficiency; (3) the scope for increased EU co-ordination; (4) the extension of White Certificates to the medium and low energy-intensive industries; (5) the need to support White Certificates with accompanying actions, such as running information campaigns, promoting energy service companies, and providing dedicated credit lines; (6) the need to develop similar instruments for transport and (7) the continuing need for energy research and development.

Regulatory and Mixed Policy Options for Reducing Energy Use and Carbon Emissions

This article discusses non-fiscal policy options to reduce energy demand and the resulting environmental impacts, and it reviews experiences with these options to date. Such policies include accelerating technology development and demonstration, stimulating product demand via procurement policies, applying efficiency standards to information-poor end-use sectors, and encouraging utility energy-efficiency programs. Efforts to implement such measures are underway in several industrialised countries and have begun in developing countries. Increasing energy efficiency is an important area for near-term carbon emission reductions, and a key strategy for cost-effective mitigation of global climate change. However, little of the energy-efficiency potential identified by technical studies will be realised in the absence of policies to reduce barriers to energy-efficiency investments. Performance standards can overcome the lack of information on the part of energy users, while technology procurement helps overcome the view of manufacturers that introducing efficient products is risky. The effects of these policy options on product markets are characterised, showing the synergy between different instruments and their potential to create and transform markets for energy-efficient products, systems and services. The existence of such energy-efficiency markets can stimulate new progress and innovation, providing the conditions in which the continuous process of technical improvement is significantly accelerated. Most policy analysis and discussions regarding climate-change mitigation have centred on various forms of carbon emission taxes and to some extent on tradable emission offsets or permits. This article concludes with an examination of why non-fiscal options are mostly absent from energy-economic models and climate-change policy studies, and we suggest approaches to include them more fully in energy-policy analysis and implementation.

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.     

Effects of waste recovery on carbon footprint: a case study of the Gulf of Bothnia steel and zinc industries

This article analyses the impact of waste recovery on climate change mitigation on a regional scale. We focus on the EU End of Waste (EoW) policy, which aims at reducing negative impacts on the environment through the minimization of generated waste. At the same time, the EU climate objectives set challenging goals for the industry to lower greenhouse gas emissions. We argue that the goals of these two policies are conflicting: under certain circumstances, the EoW will lead into increased greenhouse gas emissions because of a number of negative feedback effects that function on multiple spatial and temporal scales.To assess the effects of waste recovery on greenhouse gas emissions, we carry out a consequential life-cycle inventory on a proposed industrial ecosystem around the Gulf of Bothnia between Finland and Sweden. The system recovers currently unutilized steelmaking dust and slag from four steel mills in Finland and Sweden and converts them into iron and zinc raw materials in a novel rotary hearth furnace. The recovered iron is led back into the blast furnace of one of the steel mills and zinc is treated in an existing zinc plant. In the European scale, the model system is significant in size, serving thus as a model for integrated EoW and carbon footprint assessments in other similar cases within the EU.The analysis reveals the relative greenhouse gas emissions from raw material extraction and production, heat and power generation, transport and the production process itself, in comparison to the present system with limited material recovery. To test the model viability, we conduct a sensitivity analysis with respect to increasing energy and production capacity. Our analysis shows that from the point of view of a single operator, material recovery may bring noteworthy reductions in greenhouse gas emissions. If the scale of the assessment is expanded beyond the confines of a single plant, however, we find limited potential for reducing greenhouse gas emissions through further recovery of steelmaking residues. In conclusion, we provide policy recommendations with which the EoW paradigm can provide better support for climate change mitigation on a regional scale.
