现行环境影响报告书虽已不堪重负,但环评仅仅作为取得行政手续一纸文书的作用仍然十分明显。环评中还有很多问题受到各方质疑,基层环评人员存在普遍的迷茫。环评对控制项目最终的污染影响到底有多大的作用?环评的数据和结论为什么常常遭到怀疑?公众对环评、企业和政府为什么缺乏信任?本文以基层普通环评人员的视角,概述目前中国环评的情状和疑议,分析以前少有讨论但实际上普遍存在的问题和症结,并试图提出一些改进建议。 相似文献

This paper reviews a series of environmental indicators developed in the last years that were found suitable to be applied at corporate level for the evaluation of production processes and products. The indicators reviewed in this paper were classified into four main groups: 1) Indicators of Energy and Material Flows; 2) Indicators with a Territorial Dimension; 3) Indicators of Life-Cycle Assessment; 4) Indicators of Environmental Risk Assessment. Integrative and single index indicators such as the ecological footprint or carbon footprint were found as the most appealing for enterprises, although there is a need to advance in the field to combine the simplicity required at corporate level for tracking and reporting environmental data, and the scientific rigor and transparency necessary to make the scores reliable. Hence, for each of the indicators revised it was stated what they do and do not measure so that misleading information was not used for decision making at corporate level. 相似文献
