清洁发展机制(CDM)为<京都议定书>确立的一种基于项目的环境保护机制,它允许相关成员国在其他国家投资项目以兑现其排放削减承诺.在下,从这种为保护环境跨国投资、鼓励资金跨国的转移角度看,清洁发展机制具有合法性;而在附条件的资金转移情况下,清洁发展机制的合法性可能要受到怀疑. 相似文献

Should forest-based climate mitigationmeasures be approved for crediting through the CleanDevelopment Mechanism (CDM), they could offer anopportunity to accomplish three important objectives:cost-effective reductions in carbon emissions andsequestration of atmospheric carbon; conservation andrestoration of forests and their biological diversity;and, the assistance of host countries and communitiesin their socioeconomic development. However,prospective investors in CDM projects, host countriesand other CDM `stakeholders' might be expected toplace widely different priorities on achieving theseobjectives. This paper describes several factors thatwill affect investor interest in CDM projects, thecharacteristics of forest-based CDM projects that willattract investments, and an approach to identifyingprojects that meet the key objectives of multiplestakeholders. This approach entails identifyingsites, such as degraded watersheds, where CDMfinancing for forest conservation and restoration cangenerate readily monetizable local and regionalsocioeconomic benefits, while mitigating carbonemissions in forests with importance for conservingbiodiversity. 相似文献

The Kyoto Protocol created the Clean Development Mechanism (CDM) to allow industrial countries to reach part of their greenhouse gas (GHG) emission reduction through projects in developing countries. To calculate the achieved emission reduction a reference scenario has to be developed – the baseline. Despite efforts to develop realistic baselines, a certain degree of uncertainty regarding actual reductions will be inevitable. It is therefore necessary to compare the costs (including transaction costs) of developing a baseline against the informational benefit it can be expected to produce. While project-related baselines are already being applied, the proponents of country-related baselines have still to show the applicability of their approach for the CDM. The possibility of quantifying indirect effects and considering market distortions and subsidies through aggregation in the country-related baselines is weighed up by the manipulability and uncertainty of the assumptions required in such a baseline. Thus project-specific baselines are recommended. In cases of severely distorted markets undergoing liberalization or subsidy phase-out, a country-related baseline can be helpful. Sectoral or programme baselines would be suited to large-scale energy and sequestration projects. Moreover it has to be considered whether emission reductions are generally achieved in the context of relocation or done in the context of global emitting capacity expansion. 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.

The Clean Development Mechanism (CDM) was adopted in the Kyoto Protocol as a flexibility mechanism to reduce greenhouse gases
(GHGs) and has been started with such projects as improving efficiency of individual technology. Although applying various
countermeasures to urban areas has significant potentials for reducing GHGs, these countermeasures have not been proposed
as CDM projects in the practical stage. A CDM project needs to be validated that it will reduce GHGs additionally compared
with a baseline, that is, a predictive value of GHG emissions in the absence of the project. This study examined the introduction
of solid waste incineration with electricity generation into three different cities, A, B and C. The combination of main solid
waste treatment and fuel source are landfill and coal, respectively, in City A, incineration and natural gas in City B, and
landfill and hydro in City C. GHG emission reductions of each city under several baseline options assumed here were evaluated.
Even if the same technology is introduced, the emission reduction greatly varies according to the current condition and the
future plan of the city: 1043–1406 kg CO2/t of waste in City A, 198–580 kg CO2/t in City B, and wide range of zero to over 1000 kg CO2/tin City C. Baseline options also cause significant difference in the emission reduction even in the same city (City C).
Incinerating solid waste after removing plastics by source separation in City B increased GHG emission reduction potential
up to 730–900 kg CO2/t, which enhances the effectiveness as a CDM project.

Deforestation is currentlythe source of about 20% of anthropogenicCO2 emissions. Avoided deforestationhas, nonetheless, been ruled out as a CleanDevelopment Mechanism (CDM) category in theKyoto Protocol's first commitment period,because several methodological issues wereconsidered too difficult to resolve. Thispaper explores whether CDM issues such as(1) carbon quantification, (2)additionality and baseline setting, (3)leakage risks, (4) non-permanence risks,and (5) sustainable development can beadequately dealt with in large, diversifiedforest conservation projects. To this aim,it studies the case of the Costa RicanProtected Areas Project (PAP), anActivities Implemented Jointly (AIJ)project which was meant to consolidate thenational park system to avoiddeforestation, promote the growth ofsecondary forests and regenerate pastureson an area that, in total, covers 10% ofthe national territory. The case studyexamines how the issues mentioned abovehave been addressed in the project designand in the certification process. It isfound that baseline uncertainties are themajor problem in this case. Nonetheless,the case suggests the possibility toaddress CDM issues by specific requirementsfor project design and very conservativeand temporary crediting. Provided thatother case studies support this conclusion,eligibility of well-designed forestconservation projects under the CDM in thesecond commitment period may be worthconsidering, given the secondary benefitsof avoided deforestation. 相似文献

Activities involving land use, land-use change,forestry, and agriculture (LUCF) can help reducegreenhouse gas (GHG) concentrations in the atmosphereby increasing biotic carbon storage, by decreasing GHGemissions, and by producing biomass as a substitutefor fossil fuels. Potential activities includereducing rates of deforestation, increasing landdevoted to forest plantations, regenerating secondaryforest, agroforestry, improving the management offorests and agricultural areas; and producing energycrops.Policymakers debating the inclusion of a variety ofLUCF activities in the Clean Development Mechanism(CDM) of the Kyoto Protocol need to consider themagnitude of the carbon contribution these activitiescould make. Existing estimates of the cumulative GHGoffset potential of LUCF activities often take aglobal or regional approach. In contrast, land-usedecisions are usually made at the local level anddepend on many factors including productive capacityof the land, financial considerations of thelandowner, and environmental concerns. Estimates ofGHG offset potential made at a local, or at mostcountry, level that incorporate these factors may belower, as well as more useful for policy analyses,than global or large regional estimates. Whilecountry-level estimates exist for forestry activities,similar estimates utilizing local information need tobe generated for agricultural activities and biofuels,as well as for the cumulative potential of all LUCFactivities in a particular location. 相似文献

A community-based Clean Development Mechanism (CDM) project – asolar water heating project in a low-income community in South Africa –is analysed to illustrate the methodological and policy challenges that faceimplementation of the Kyoto Protocol to the United Nations FrameworkConvention on Climate Change. We evaluate four baseline options, andthree potential CDM interventions. The emissions reductions range from –670 to +5 929 Mg CO2 per year, with all option but oneshowing positive emission reductions. Using metered solar water heatingwith liquefied petroleum gas back-up as the CDM intervention, and electricstorage geysers as the baseline, the annual emissions reductions are 5686 Mg CO2. The cost-effectiveness from the national perspective,which is the incremental life cycle costs divided by the lifetime emissionsreductions, is –$18 per Mg CO2 From the perspective of theCDM investor, however, the cost-effectiveness is $5.2 per mgCO2, assuming that the investor receives all of the carbon credits forproviding the incremental capital investment. From our analysis, weconclude that using the current technology (kerosene stoves) as a baselineis probably not appropriate because it does not reflect likely future trendsand also penalises the community for their poverty and current lack ofinfrastructure. We also highlight the importance of credit sharing, and howit affects the cost-effectiveness of the project from the CDM investor'sperspective. The lessons from this analysis are important for the currentinternational policy debate on how to preferentially treat small-scale CDMprojects. 相似文献
