The East-West Center convened the international conference on climate policy in Honolulu, Hawaii, on September 4–6, 2003. Sponsored by the Dutch Ministry of Housing, Spatial Planning and the Environment, the Japanese Ministry of the Environment, Industrial Technology Research Institute (Taiwan), and Institute for Global Environmental Strategies (Japan), this major event covered almost every important issue and featured perspectives from the most important parties and stakeholders in formulating and implementing climate policies and taking international climate negotiations further. It brought together a remarkable cross-section of world opinion on climate policy after Kyoto. This report provides a summary of each presentation and highlights discussions organized under the following six session headings: Session 1: Climate Change in Focus – From Science to Policy; Session 2: U.S. Climate Policy and Perspectives; Session 3: European Union Climate Policy and Perspectives; Session 4: Challenges for other Major Industrialized Countries; Session 5: Issues Related to Developing Countries; and Session 6: Panel Discussions: Where Do We Go from Here?. 相似文献

在环境换取经济增长向环境优化经济增长转变的新彤势下.应拓展建设项目环境保护设施竣工验收监测的内涵。指出目前的竣工验收监测对工业生产型建设项目的制约因素考虑不周、忽视了“三同时”的垒过程、忽视了非工业生产型建设项目和区域性开发项目、忽视了无组织排放污染源。提出要创新治理设施竣工验收监测理念、优化竣工验收监测方法、强化竣工验收生态监测技术的研究、开展区域性建设项目的验收监测。 相似文献

Adaptation is nowrecognized as an inevitable component ofthe overall climate change responsestrategy. For a developing region likesub-Saharan Africa with low greenhouse gasemissions and high vulnerability to theimpacts of climate change, the importanceof adaptation in climate change policy iseven more fundamental. This paper examined alook at the adaptational preparedness ofthe sub-Saharan African region to climatechange. Clearly evident in theenvironmental strategy and developmentfocus of these countries is lack ofrecognition of the need to adapt, poorincentive to adapt and low capacity toadapt to climate change. This furtherexacerbates their vulnerability and hasimplications for the global climate changeresponse strategy. Unfortunately, fewattempts have been made to understand thestructural reasons underlying the pervasivepattern of adaptational unpreparedness inthe region, neither has there been acomprehensive and systematic analysis ofhow to remedy this problem. This paper is acontribution in this regard. It alsohighlights the factors to whichinternational community need to payattention, if it truly wishes to make itsefforts at adaptation more global inscope. 相似文献

Fuelwood plays an important role in the rural economy of the developing countries of Asia and Africa. Optimizing energy fixation
in forest trees through high density energy plantations (HDEP), gasification of wood, and conversion of forest tree biomass,
are some of the potential areas whereby additional research and development input for efficient management of atmospheric
carbon in our energy system can be incorporated. For example, the photosynthetic efficiency of forest trees is rarely above
0.5%, which on the basis of theoretical considerations can be increased by up to 6.6%. Thus there is an ample scope to improve
the efficiency up to 1%, which amounts to doubling of the productivity of the forests.
Recent policy changes and experiences with wood-based bio-energy programmes in several countries indicate that woodfuels may
become increasingly attractive as industrial energy sources. Use of biodiesel and the formulation of a project for undertaking
13.4 million ha of Jatropha plantations in India highlight the seriousness with which the Government of India is promoting carbon neutral energy plantations.
The cost of establishment of plantations primarily for fuel production and its conversion to energy are major deterrents in
this pursuit. Some of the issues in developing countries, like low productivity on marginal lands, degraded forest lands,
and unorganized units for biomass energy conversion, result in cost escalation as compared to other energy sources. This paper
revisits the scope for raising energy plantations, a comparison of the direct and indirect mitigation potential uses of plantations
as an adaptation strategy through reforestation and afforestation projects for climate change mitigation and socio-economic
issues to make this venture feasible in developing countries. 相似文献
