Sustainable development in the Clean Development Mechanism: the role of Designated National Authority in China and India

The Clean Development Mechanism (CDM) emerged under the Kyoto Protocol to facilitate collaboration between developed and developing countries in order to mitigate greenhouse gases. The CDM allows developed countries to receive credits towards meeting their obligatory targets by investing in emission reduction projects in developing countries. The countries are required to set up a Designated National Authority (DNA) to approve the CDM projects. This paper examines the role of the DNA in ensuring sustainable development, using the empirical case of China and India. Three aspects of the DNA's role are examined: the institutional structure, the policy context and the CDM project market. All three aspects highlight the important role of the DNA in meeting the countries' sustainable development priorities.     

二氧化碳捕获和存储作为清洁发展机制项目的潜力与障碍分析

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。     

The effects of large-scale afforestation and climate change on water allocation in the Macquarie River catchment,NSW, Australia

Widespread afforestation has been proposed as one means of addressing the increasing dryland and stream salinity problem in Australia. However, modelling results presented here suggest that large-scale tree planting will substantially reduce river flows and impose costs on downstream water users if planted in areas of high runoff yield. Streamflow reductions in the Macquarie River, NSW, Australia are estimated for a number of tree planting scenarios and global warming forecasts. The modelling framework includes the Sacramento rainfall-runoff model and IQQM, a streamflow routing tool, as well as various global climate model outputs from which daily rainfall and potential evaporation data files have been generated in OzClim, a climate scenario generator. For a 10% increase in tree cover in the headwaters of the Macquarie, we estimate a 17% reduction in inflows to Burrendong Dam. The drying trend for a mid-range scenario of regional rainfall and potential evaporation caused by a global warming of 0.5 degree C may cause an additional 5% reduction in 2030. These flow reductions will decrease the frequency of bird-breeding events in Macquarie Marshes (a RAMSAR protected wetland) and reduce the security of supply to irrigation areas downstream. Inter-decadal climate variability is predicted to have a very significant influence on catchment hydrologic behaviour. A further 20% reduction in flows from the long-term historical mean is possible, should we move into an extended period of below average rainfall years, such as occurred in eastern Australia between 1890 and 1948. Because current consumptive water use is largely adapted to the wetter conditions of post 1949, a return to prolonged dry periods would cause significant environmental stress given the agricultural and domestic water developments that have been instituted.     

Possibilities and options for the Clean Development Mechanism and the Green Investment Scheme in Central and Eastern Europe: Macedonian and Romanian perspectives

Central and Eastern Europe (CEE) is a rapidly changing and developing region which is making the transition to a market based economy. Along with economic reforms, the countries of the region are engaged in substantial environmental reforms, including climate change mitigation activities. Mitigation of, and adaptation to, the consequences of climate change are costly processes. It is therefore of great importance that the national and international mechanisms addressing these problems use methods both environmentally sound and economically efficient. Through two case studies that address the Clean Development Mechanism (CDM) in the Former Yugoslav Republic of Macedonia, and the Green Investment Scheme (GIS) in Romania, this paper explores challenges, related tasks and main problems in the establishment of mechanisms of the Kyoto Protocol in Central and Eastern Europe.

朝阳开发区造纸工业园建设可持续发展研究与实践

针对朝阳开发区造纸工业园控制性详细规划,采用层次分析法构建规划环境影响评价指标体系,在此基础上,分析朝阳开发区造纸工业园建设的可持续发展水平,为朝阳开发区造纸工业园建设环境决策的科学性提供技术依据。朝阳开发区造纸工业园区域发展规划实施后,规划各期区域整体可持续发展水平基本保持稳定,均为Ⅲ级,即可持续发展水平为中等。经济子系统和社会子系统可持续发展水平各期逐渐下降,而环境子系统可持续发展水平各期呈上升趋势。这说明,随着园区的进一步发展,其环境效益日益明显。
