This paper studies the emergence of one particular 'new' environmental policy instrument: disclosure of emission and pollution data. Disclosure is part of a relatively new sub-set of regulatory measures, based on monitoring, transparency, citizen-empowerment and accountability. It originated in the United States but has recently attracted international attention. The attractiveness of disclosure is obvious; it promises environmental improvement combined with strengthened environmental democracy and community empowerment. By analysing the experiences in the US, and the developments in the Netherlands, this paper seeks to assess the functioning and effectiveness of disclosure. The available empirical evidence suggests that disclosure has a positive impact on the environmental performance of industrial facilities as well as a democratising effect. It is argued that Dutch policy makers wrongfully assume that disclosure cannot work in the Netherlands. The consequence is that citizens are provided with little specific information that cannot be used to put pressure on polluters. 相似文献

Although the importance of understanding stakeholder beliefs regarding environmental policy has been noted by many authors,
research focusing on the heterogeneity of stakeholder views is still very scarce and concentrated on a product-oriented definition
of stakeholders. The aim of the present study is to address this gap by examining environmental policy beliefs of stakeholder
groups engaged in protected area management. Questionnaires containing 73 five-point Likert scale items were administered
to eight different stakeholder groups involved in the management of Greek protected areas. Items referred to core beliefs
on environmental policy, namely, the value framework and sustainable development, and secondary beliefs, that is, beliefs
on social consensus and ecotourism development. Our study used as a starting point respondent recruitment on the basis of
a traditional product-centered approach. We investigated whether environmental policy beliefs can be used to effectively segregate
stakeholders in well-defined segments, which override the product-oriented definition of stakeholders. Indeed, K-means clustering
revealed an innovation-introduction and an implementation-charged sample segment. The instrument utilized in this research
proved quite reliable and valid in measuring stakeholder environmental policy beliefs. Furthermore, the methodology implied
that stakeholder groups differ in a significant number of belief-system elements. On the other hand, stakeholder groups were
effectively distinguished on a small set of both core and secondary beliefs. Therefore, the instrument used can be an effective
tool for determining and monitoring environmental policy beliefs of stakeholders in protected area management. This is of
considerable importance in the Greek case, given the recent establishment of 27 administrative bodies of protected areas,
all of which are required to incorporate public consultation into management practices. 相似文献
