关于建设项目生态补偿的思考

作为一种解决环境保护与经济社会发展矛盾的重要经济手段,生态补偿越来越受到人们关注。建设项目生态补偿是生态补偿的一个重要领域,但相对于其他领域而言,理论和实践研究均相对较少。结合实际案例研究,文章初次提出了建设项目生态补偿概念、原则及应注意的问题。最后,建议加强两方面研究,建设项目生态补偿内涵和范畴确定;建设项目生态补偿方式及标准确定。

Tracking the implementation of green credit policy in China: top-down perspective and bottom-up reform

The Chinese government has introduced the green credit policy to mitigate the environmental impact of industrialization by reining in credit loans to companies and projects with poor environmental performance. This research investigated the implementation of the green credit policy both at the national and provincial levels. Our results show that the green credit policy is not fully implemented. The wide-ranging impact on high-polluting and high energy-consuming industries, vague policy details unclear implementing standards, and lack of environmental information are the main problems in the implementation of the green credit policy in China. On the other hand, the practice at local level (Jiangsu Province) is more practical by integrating green credit policy with the environmental performance rating system. Finally, suggestions are outlined to improve China's green credit policy.     

Compliance of Australian threatened species recovery plans with legislative requirements

Recovery plans are the main documents supporting management decision-making for threatened species. We evaluated Australian recovery plans to assess their appropriateness as conservation and management planning instruments. Six legislative requirements (species information and general requirements, species distribution and location, known and potential threats, objectives, performance criteria and actions, duration of the plan, and estimated costs of plan implementation) were used to assess the degree of compliance of recovery plans with the relevant legislation. We assessed all 236 official recovery plans which had been adopted as at January 2006. The results showed that plans were most compliant regarding the setting of objectives, performance criteria, recovery actions, and duration of plan. Most plans included a single performance criterion that was generally related to the population status of target species. Improvement is required in relation to identification of current threats and critical habitats, and the establishment of basic elements of monitoring and evaluation for measuring recovery progress. Gaps in ecological information are the main factors affecting adequate compliance with legislative requirements as opposed to managerial information (e.g. clarity in establishing the implementation schedule, costs and resource allocation). Planning deficiencies could be addressed by improving the recovery planning guidelines and more carefully reviewing the drafting and adoption of new plans.     

Evaluating coal bed methane investment in China based on a real options model

In this paper, a real options based binominal lattices model for the investment of coal bed methane (CBM) is conducted. CBM prices and market demand are incorporated into the model as the predominant uncertain factors and it is solved by using the bidimensional binominal lattices approach. Then the model is employed to evaluate the investment in CBM projects in China, and the effect of related policies is analyzed. The empirical results demonstrate that the model can be used to offer a better explanation of why the CBM industry has developed slowly in China from an investment perspective. It is found that the current policy environment is not positive enough to attract investment in the CBM industry. Among various factors, CBM prices yield the most significant effect on stimulating investment in CBM development. Increasing the price subsidy is also an effective policy to stimulate investment and promote the development of the CBM industry in China.     

Landfill diversion in a decentralized setting: A dynamic assessment of landfill taxes

We analyze the process of landfill diversion and its main determinants, by embedding the dynamics in a frame where economic, geographical and policy variables come into play. In addition to structural and economic drivers, we primarily investigate whether the Italian tax has been effective in supporting landfill diversion. Although the Italian landfill tax dates back to 1996, the oldest in the EU, its effectiveness in terms of landfill diversion has not been assessed yet. The complexity primarily derives from the decentralized regional implementation and the absence of a full coherent dataset covering all regions. We merge this new and original data on taxes to an integrated dataset which includes economic, waste and policy variables at regional level over the period 1999–2008. Panel regressions show that the effect of tax is significant, even when taking into account for its possible endogeneity. Regions that have increased such taxes have improved waste disposal performances over time. Landfill taxes are surely not the only instrument policy makers might introduce, but they seem to play a relevant role in the evolution of Italian waste disposal performances.     

Information requirements of integrated environmental policy experiences in the Netherlands

During the last few years in the Netherlands an integrated environmental policy has been developed. Solving environmental problems by means of effective and efficient solutions requires that the entire environmental cycle be considered in order to take all relevant compartments and aspects into account. Four different phases can be identified during the treatment of an environmental problem by management: recognition, formulation, solution, and control.Some qualitative and quantitative aspects of the information demand of environmental policy are explored. Special attention is given to the consequences of the integral approach in environmental policy in terms of information requirements. The process of information supply starts with an analysis of the demand. Subsequently data from the environmental cycle have to be selected, aggregated, and presented adequately. Further, integrated environmental policy puts increased demands on the associative power of environmental information systems.

Integrating lidar and satellite optical depth with ambient monitoring for 3-dimensional particulate characterization

A combination of in-situ PM_2.5, sunphotometers, upward pointing lidar and satellite aerosol optical depth (AOD) instruments have been employed to better understand variability in the correlation between AOD and PM_2.5 at the surface. Previous studies have shown good correlation between these measures, especially in the US east, and encouraged the use of satellite data for spatially interpolating between ground sensors. This work shows that cases of weak correlation can be better understood with knowledge of whether the aerosol is confined to the surface planetary boundary layer (PBL) or aloft. Lidar apportionment of the fraction of aerosol optical depth that is within the PBL can be scaled to give better agreement with surface PM_2.5 than does the total column amount. The study has shown that lidar combined with surface and remotely sensed data might be strategically used to improve our understanding of long-range or regionally transported pollutants in multiple dimensions.     

A framework on interactions of climate and energy policy instruments

In this paper we analyze the concept of interactions between policy instruments addressing environmental, energy and climate change issues. Although discussion on such policies has been taking place for almost two decades, their interactions are not so sufficiently explored. Initially, we refer to literature on various types of interactions and we classify them. Furthermore, we construct a qualitative method that can assist policymakers in selecting an optimal policy mix. This method breaks down into numerous components, the areas where different policies interact, and facilitates the unveiling of potential overlaps and complementarities. These areas consist of categories as measure identification, objectives, scope, market arrangements, market flexibility, financing, technological parameters, timing, compliance parameters and institutional setup. In addition, it renders the possibility of combining different options and design elements of policies. Furthermore, a list of various criteria serves as an assessment tool for interactions, where a weighing factor and uncertainty parameters have been added, in order to produce an aggregate indicator of the ex-ante analysis of the policy mix selected. Through this method, we present a complete framework of discernment of diverse forms of environmental policy instruments.
