承德市武烈河水环境容量核算与减排效益评估研究

水环境容量核算能为水污染防治提供科学依据,而工程减排效益分析能为水污染防治提供优先顺序,两者都直接关系到流域总量减排任务的完成和水质目标的实现。以承德市武烈河为例,根据水环境容量核算的基本原理,结合污染状况、水质现状和水环境功能区划,对COD和氨氮的水环境容量进行核算;结合流域污染防治规划,以输入响应关系为基础,对两类主要污染防治工程的水环境质量减排效益进行评价。结果表明,武烈河COD、氨氮水环境容量分别为1 519.7、159.6t/a,水环境容量处于超载状态;主要污染防治工程能大幅削减污染物排放量,对改善水环境质量贡献明显,工程的落实将有利于改善武烈河水环境现状。     

三峡库区农村生活垃圾处理支付意愿及影响因素分析

农村生活垃圾的集中化、科学化处理对改善农村居民生活环境和农业生产环境具有重要意义。而农户对农村生活垃圾处理的支付意愿对农村生活环境的改善具有关键性作用。采用条件价值评估法(CVM)分析了三峡库区农户对处理生活垃圾的支付意愿及其影响因素。结果表明:(1)农户对农村生活垃圾处理的平均支付意愿为48元/a;(2)户主年龄、文化程度以及对环境是否关心对当地农户处理生活垃圾的支付意愿有极显著影响。户主年龄和文化程度对生活垃圾处理的支付意愿的影响为正,说明农户年龄越大、文化程度越高,对生活垃圾处理的支付意愿就越强烈。农户对环境的关心程度为正,表示农户越关心环境,对生活垃圾处理的支付意愿就越强烈。最后,提出相关建议:制定政策时要充分考虑农户的个体特征和自身利益;加强教育,提高农户的文化水平;加强环境保护宣传,提高农户的环境认知和环保意识。

Environmental Auditing—A Timely and Effective Tool

The requirements of environmental regulations imposed on industry are complex and expensive. As these regulations have developed, corporate compliance programs have had to become more sophisticated. For many, this means that an environmental auditing program is now timely (or overdue) for organizing their approach to meeting the constraints of these regulations. Contributing to this timeliness is a renewed emphasis by regulators on enforcement activities. This paper discusses what environmental auditing is and what it consists of, gives examples from a few approaches which are currently being used, and reviews some of its benefits and liabilities.     

A Practical Look at Environmental Audits

Company self-auditing has become an increasingly attractive option for both government and industry in achieving compliance with environmental laws. For government, it can diminish the need for continual compliance inspections, and, for industry, it can prevent substantial liability. However, auditing can be conducted in a number of ways, and it is important for company management to be aware of its options before selecting a particular approach. This is particularly true of companies with relatively limited resources for such a project. The following article describes some of the more basic options to be considered In identifying an optimal auditing strategy. It also discusses factors which may make one strategy preferable to another. The article concludes with the interesting observation that, in some cases, a formal audit may be neither necessary nor desirable.     

Cost-benefit analysis as a tool for decision making in environmental projects

BACKGROUND, AIM AND SCOPE: The Damage-Function method is an efficient tool recently used in decision-making processes concerning environmental management. It is based on finding the relation between the origin of an environmental charge, and its impact on human health and the environment. The aim of the present investigation was to assess the positive impacts, also called benefits, of changes in environmental quality, and the economic viability of an industrial project on reduction of PCDD/F emissions. It has been developed with monetary criteria of two worldwide ambits: USA and European-Union countries. METHODS: The current study is a continuation of a previous investigation in which Substance Flow Analysis and Control Analysis Techniques were used to identify and to analyze all main flow values of PCDD/Fs inside the system of Tarragona Province (Spain). In the present study, Cost-Benefit Analysis (CBA) has been employed. The benefits derived from a minimization in the incidence of cancer due to a reduction in the emission of PCDD/Fs have been evaluated considering the value of a statistically saved life (VSL). Statistical analysis about uncertainty has also been incorporated. Here, the Monte Carlo simulation technique has been used. RESULTS: It is shown that CBS results depend firstly on the kind of VSL used. In fact, the differences between the decisions as a result of applying monetary criteria in USA and EU can be explained by differences between VSL values. CONCLUSION AND RECOMMENDATION: It is concluded that, for prices estimated in Euros, the emission cleaning project in the industrial plant is not feasible under any circumstance. However, although CBA seems to be a good analytical method, the final decision corresponds to the managers, who must weigh up not only the monetary criteria, but factors such as social questions.

Combined role of industrialization and urbanization in determining carbon neutrality: empirical story of Pakistan

A rapid process of industrialization, on the one hand, transformed the economies from agrarian to industrial societies to improve the living standards and welfare of people. On the other hand, the urbanized and industrialized economies have posed challenging threats to environmental sustainability. The query at hand is whether the growing environmental emissions are driven by industrialization and urbanization or not. This research aims to empirically examine the combined role of industrialization and urbanization in achieving carbon neutrality in Pakistan by considering foreign direct investment and economic growth as control variables in the model. The core empirical results are the following: firstly, industrialization and economic growth exhibit negative but statistically insignificant impacts on CO₂ emissions, imparting a neutral role in determining the environmental degradation in Pakistan. Secondly, urbanization and foreign direct investment disclose positive and statistically significant (at 1% level of significance) impacts on CO₂ emissions, manifesting an environmental degradation driving impact in the country. Thirdly, given the slope coefficients of urbanization and foreign direct investment (0.058 and 0.035), urbanization proved to be a stronger driver than foreign direct investment. Finally, foreign direct investment is revealed to make the Pakistani economy a “Pollution Haven” for the foreign enterprises in the country. Based on empirical results, none of the variables predicted the support for carbon neutrality in Pakistan.
