Scientific quality in a technical policy document is defined in terms of the proportion of contemporary scientific principles on a subject that the document competently discusses. As a case study of the scientific quality of such documents, this articles examines the treatment of acid deposition effects in 126 environmental impact statements on fossil-fuel power plants. On average, the relevant environmental statements cover only a quarter of the eligible scientific principles. Bureaucratic and political factors influence the quality of discussion of acid deposition more than do strictly objective or scientific factors. In particular, public participation and interagency review processes foster relatively thorough consideration of scientific information in environmental impact statements. 相似文献

我国目前的生活社区污染物治理方式主要是收集后集中处理,这种处理方式存在若干问题,如会影响集中处理场所和转运沿线周边社区的环境质量、不利于处理产物的资源化利用、收集系统的成本较高等。文章提出生活社区污染物宜就地处理,使本社区的污染物不会转移到其他社区,同时便于污染治理产物的资源化利用,而且可以促进环保产业升级,提高农村社区居住环境质量,促进绿色农业的开展,减轻政府环保工作压力。 相似文献

上市公司高管态度对企业环境信息披露会产生重要影响。为充分了解企业高管如何看待上市公司环境信息披露过程中涉及的环境信息沟通、披露制度、能力建设等多方面问题,本文对涉及第一、第二和第三产业的16家上市公司高管进行访谈调研。研究发现,多数高管视社会第三方机构对企业的环境信息需求为较大的潜在风险,非强制是上市公司环境信息选择性披露的主要原因,企业重视环保投资但信息公开能力建设不足,环境信息公开对企业价值影响较弱。本文提出编写环境信息公开指南及实施细则,提升企业环境信息公开的能力建设,拓展政府和社会组织对企业环境信息公开的奖励形式等建议。 相似文献

近年来,公众已经成为中国环境治理中不可或缺的力量,公众参与的方式和渠道也在不断拓展和丰富。为考察不同类型公众参与方式对环境治理效果的影响差异,本文基于公众参与阶梯理论,选取四类公众参与方式和四类污染物,结合我国2008—2017年30个省份数据,利用面板数据回归模型进行了实证检验。结果表明,横向比较不同类型的公众参与方式,公众环境来访对环境治理的促进效果优于环境信息公开和环保网络舆论,而政协提案、人大议案的积极效应尚不显著。纵向比较不同类型的污染物治理效果,公众参与能显著促进大气污染物的减排,对噪声和固体废物污染效果的影响次之,而在水污染治理中的作用较不理想。建议政府进一步优化健全环境信息公开机制,并重视公众层面的环境诉求,建立公众与地方生态环境部门的良好互动机制,同时鼓励公众通过新媒体渠道参与环境治理。 相似文献

The management system for solid and liquid organic waste affects the environment and surrounding technical systems in several ways. In order to decrease the environmental impact and resource use, biological waste treatment and alternative solutions for sewage treatment are often advocated. These alternatives include increased agricultural use of waste residuals. To analyse whether such proposed systems indicate improvements for the environment and its sustainability, systems analysis is a useful method. The changes in environmental impact and resource use is not only a result of changes in waste treatment methods, but also largely a result of changes in surrounding systems (energy and agriculture) caused by changes in waste management practices. In order to perform a systems analysis, a substance-flow simulation model, the organic waste research model (ORWARE), has been used. The results are evaluated by using methodology from life cycle assessment (LCA). An economic analysis was also performed on three of the studied scenarios. The management system for solid organic waste and sewage in the municipality of Uppsala, Sweden, was studied. Three scenarios for different treatments of solid waste were analysed: incineration with heat recovery, composting, and anaerobic digestion. These three scenarios included conventional sewage treatment. A fourth scenario reviewed was anaerobic digestion of solid waste, using urine-separating toilets and separate handling of the urine fraction. The results are only valid for the case study and under the assumptions made. In this case study anaerobic digestion result in the lowest environmental impact of all the solid waste management systems, but is costly. Economically, incineration with heat recovery is the cheapest way to treat solid waste. Composting gives environmental advantages compared to incineration methods, without significantly increased costs. Urine separation, which may be implemented together with any solid waste treatment, has great advantages, particularly in its low impact on the environment. However, there is a large increase in acidification. 相似文献
