在分析环境保护市场化推进经验与制约瓶颈的基础上,从公共物品、准公共物品和私人物品特征明显的环境保护领域3个方面提出了环境保护市场化推进的重点领域与推进机制,并从加大监察执法力度、优化专项资金使用、强化政策引导和加强环保市场监管等方面提出了环境保护市场化的推进措施与建议。  相似文献

为提高湖滨带管理水平,通过总结实际工作中的工作方法和经验,提出和完善滇池湖滨生态带管理的一般模式,即政府投资管理、企业投资管理、政府-企业共同管理三种模式,为构建完善的滇池湖滨生态带管理机制奠定理论研究和实践调研基础。结果表明:政府主导的管理方式有利于保障湖滨带的整体性和自然属性,促进湖滨带生态系统的自然恢复,但是资金投入比例大、管理周期长;政府-企业共同管理能产生社会效益和经济效益,降低政府投资;企业投资管理能激活湖边带的商业价值,但企业管理自主性比较大,有待进一步研究。  相似文献

There is a growing assumption that payments for environmental services including carbon sequestration and greenhouse gas emission reduction provide an opportunity for poverty reduction and the enhancement of sustainable development within integrated natural resource management approaches. Yet in experiential terms, community-based natural resource management implementation falls short of expectations in many cases. In this paper, we investigate the asymmetry between community capacity and the Land Use Land Use Change Forestry (LULUCF) provisions of the Clean Development Mechanism within community forests in Cameroon. We use relevant aspects of the Clean Development Mechanism criteria and notions of “community capacity” to elucidate determinants of community capacity needed for CDM implementation within community forests. The main requirements are for community capacity to handle issues of additionality, acceptability, externalities, certification, and community organisation. These community capacity requirements are further used to interpret empirically derived insights on two community forestry cases in Cameroon. While local variations were observed for capacity requirements in each case, community capacity was generally found to be insufficient for meaningful uptake and implementation of Clean Development Mechanism projects. Implications for understanding factors that could inhibit or enhance community capacity for project development are discussed. We also include recommendations for the wider Clean Development Mechanism/Kyoto capacity building framework.  相似文献

改善环境质量是环境保护的核心。当前,我国跨省界流域上下游治污协作机制尚未完全建立,权责落实与激励政策尚不完善,流域跨省界断面水质短期内难以得到根本改善。文章提出建立以水环境质量改善为导向的跨省财政激励机制,根据上下游出境断面水污染治理成本、水生态价值和发展机会成本以及延伸投入等,强化流域水质目标考核行政和经济"双重"约束机制,建立水质超标"罚款赔偿"和水质达标"奖励补偿"机制,是解决流域跨界污染问题的重要突破口,并建议"十三五"全面推动建立跨省断面水质财政激励机制,实现流域治理的成本共担、合作共治。  相似文献

本文目的在于讨论和分析二氧化碳捕获和储存技术项目(CCS)作为清洁发展机制(CDM)项目的障碍和机遇。CCS被视为减少CO2人为排放量的选择方案之一,但在发展中国家,该技术面临着政策、成本和技术上的挑战。对这些国家而言,CDM几乎是发展CCS的唯一动机。本文分析了CCS作为CDM项目面临的项目边界、持久性、渗漏和可持续发展性的问题,并展望了未来的发展趋势。  相似文献

Under the Clean Development Mechanism (CDM) of the Kyoto Protocol, industrialised countries may finance greenhouse gases mitigation projects in developing countries. The Kyoto Protocol explicitly requires that the CDM shall assist developing countries to achieve sustainable development. However, a clear definition of sustainability for CDM projects is still debatable. MATA-CDM (Multi-Attributive Assessment of CDM Projects) is an approach that facilitates a quantitative assessment of potential projects regarding their contribution to sustainable development. This paper presents applications of MATA-CDM in two different countries. In South Africa, the application was done mainly for academic and demonstrative purposes, whereas in Uruguay it was implemented together with the responsible Designated National Authority (DNA). The work in both countries included the selection of sustainability criteria and measurable indicators. Experts weighted the criteria using personal interviews and a multi-stakeholder workshop. This method was applied to three potential CDM projects in South Africa and one in Uruguay. Results show that under the conditions of this study, the MATA-CDM approach yet fails to yield a perfect quantitative overall sustainability assessment of CDM projects but that several findings could be useful to further develop the approach with the aim to translate the vague term sustainable development to a mainstream project level. Valuable experience was in particular collected with different stakeholder processes to perform criteria weighting.  相似文献

In the transport sector, few projects applied Clean Development Mechanism (CDM) or Joint Implementation (JI) projects. This study will examine the feasibility of applying CDM to the transport sector from viewpoints of validation of processes and funding. A number of greenhouse gas emission reduction projects, as well as traffic management project within existing transport infrastructures, can be implemented as CDM projects. New transport infrastructure projects can be validated by transportdemand forecasting and traffic simulation methods, though application of Life Cycle Assessment (LCA) and Intelligent Transport Systems (ITS) technologies. This revised version was published online in August 2006 with corrections to the Cover Date.  相似文献

One of the dual objectives of the Clean Development Mechanism (CDM) of the Kyoto Protocol is to assist host countries in achieving sustainable development. With various CDM indicators for 58 CDM host countries over the period 2005‐2010, this paper empirically assesses whether CDM project development fulfils its sustainable development objective. Using a unique dynamic panel data method based on the long‐differenced model, this research provides convincing evidence that CDM projects contribute to sustainable development in host countries. It sheds light on the role of the CDM in the process of global sustainability with clear policy implications for developing countries and those embracing market instruments.  相似文献
