我国小型CDM项目开发障碍及其对策研究

2005年《京都议定书》生效以来,我国一直是全球CDM开发的重要国家之一,在CDM开发方面取得显著成就。但是由于信息流通、项目规模以及市场因素的影响,我国小型CDM项目在开发范围和深度方面都存在显著的不足。在对以上原因进行分析的基础上,本文认为采取多个小项目打包开发、以地区为单位整体开发以及促进CDM信息交流等方法可以解决以上阻碍小项目开发的因素,促进我国CDM健康发展。     

贵阳市城区路侧土壤重金属分布特征及污染评价

研究了贵阳市城区各交通干线两侧表层土壤中重金属的质量分数、空间分布特征及其影响因素.以基线作为参比值,采用地积累指数法对其污染程度进行评价.结果表明:各交通干道两侧土壤中重金属质量分数存在显著差异,除Pb和Cr外,其余重金属质量分数均高于中国表层土壤重金属元素背景值和贵阳市表层土壤重金属元素基线值. 整体上,贵阳市路侧土壤尚未受到Pb和Cr的污染,其w(Hg),w(Cd)和w(Zn)已达中度污染甚至强污染水平,同时各路段也受到了不同程度的As,Cu和Ni污染,但并不严重. 据调查,路侧土壤中重金属质量分数及其分布格局主要受到燃煤、交通运输、地形及路况、气象因素以及城市建设等的影响.      

Simulative governance: on the collaborative narrative of civil society participation in the CDM stakeholder framework

The Kyoto Protocol’s Clean Development Mechanism (CDM) is often cited as an exemplar of new, hybrid forms of global environmental governance operating at the public–private interface. Practically, enacting this arrangement involves a wide range of non-state actors. This broad involvement is here assumed to mark a shift towards more polycentric and networked modes of governance in which agents collaborate as ‘stakeholders’ in the process of consensual rule-setting and implementation. Using post-political critique, the depoliticising effects of the stakeholder framework on civil society actors are interrogated, using formal and informal participation opportunities to raise concerns regarding specific CDM projects. The analysis suggests that the CDM’s collaborative narrative of stakeholding structurally fails to stimulate public (re)engagement and is, instead, a prime example of simulative governance that struggles to achieve the simultaneity of two incompatibilities: the participatory revolution and the post-political turn.     

The Clean Development Mechanism and Sustainable Development in China's Electricity Sector

Abstract

The Clean Development Mechanism, a flexibility mechanism contained in the Kyoto Protocol, offers China an important tool to attract investment in clean energy technology and processes into its electricity sector. The Chinese electricity sector places centrally in the country's economy and environment, being a significant contributor to the acid rain and air pollution problems that plague many of China's cities and regions, and therefore a focus of many related energy and environmental policies. China's electricity sector has also been the subject of a number of economic analyses that have showed that it contains the highest potential for clean energy investment through the Clean Development Mechanism of any economic sector in China. This mechanism, through the active participation from investors in more industrialized countries, can help alleviate the environmental problems attributable to electricity generation in China through advancing such technology as wind electricity generation, clean coal technology, high efficient natural gas electricity generation, or utilization of coal mine methane. In this context, the Clean Development Mechanism also compliments a range of environmental and energy policies which are strategizing to encourage the sustainable development of China's economy.     

Application of Tradable Emission Permits in Europe

Abstract

The purpose of this study is merely to review the current situation in the designing and implementation of the emission trading programs in Europe. Historical data show that although there is a series of shortcomings in their current functioning, employing such instruments for GHG reduction policy making is strongly expected to be efficient and effective. The European Union Emission Trading Scheme (EU ETS), Clean Development Mechanism (CDM) and Joint Implementation (JI) are just a few examples of the ambitious EU initiative that heavily relies on such instruments. We dwell on their operations and achievements by far and all the content in this article is expected to convince the Chinese government and regional public authorities to take positive actions and attitudes in promoting these instruments.     

The Clean Development Mechanism and Sustainable Development in China''''s Electricity Sector

1 INTRODUCTIONEnergy and environmental issues in China have receivedsignificant attention in both the peer-reviewed literatureand in international energy and environmental policymaking in the last number of years. China's coal dominatedenergy consumption results in significant regional pollutionproblems, most notably acid rain that affects nearly 1/3rdof China's landmass and air pollution that plagues manyof its major cities. China now ranks as the top emitterof sulphur dioxide (SO2) pol…

造林/再造林CDM项目PDD编写中几个重要问题探讨

造林/再造林CDM项目PDD编写在整个CDM项目的实施上占有举足轻重的地位,由于造林/再造林CDM项目目前还处于起步阶段,其中的很多问题还亟待解决,这就造成了PDD编写中必然会存在很多不确定的问题。在造林/再造林CDM项目PDD编写整个流程中涉及到最重要的环节的问题则是解决其他问题的关键。在这些关键问题中包括三个非常重要的问题：基线,额外性,泄漏。本文对这三个问题分别进行阐述,并试着提出相应的解决方法予以探讨。     

Socioeconomic potential of carbon sequestration through agroforestry in the West African Sahel

The recognition of agroforestry as a greenhouse-gas mitigation strategy under the Kyoto Protocol to the United Nations Framework Convention on Climate Change (UNFCCC) offers an opportunity to agroforestry practitioners to benefit from the global Carbon (C) credit market. Our knowledge on this important topic from the semiarid regions such as the West African Sahel (WAS) is, however, very limited. In order to fill this gap, this study was undertaken in the Ségou region of Mali (annual temperature, 29°C; annual rainfall, 300–700 mm in 60 to 90 days), focusing on two improved agroforestry systems (live fence and fodder bank) along with traditional parkland agroforestry systems of the region. A cost–benefit analysis was conducted to assess the economic profitability and risks associated with the systems considering them as 25-year projects and their potential for participation in C credit market. The traditional systems had high C stock in their biomass and soil, but little potential for sequestering additional C; on the other hand, the improved systems had low C stock, but high sequestration potential. For the standard size live fence (291 m) and fodder bank (0.25 ha) projects, the estimated net present values (NPV) were $ 96.0 and $158.8 without C credit sale, and $109.9 and $179.3 with C sale, respectively. From the C sale perspective, live fence seemed less risky and more profitable than fodder bank. Carbon credit sale is likely to contribute to economic development of the subsistence farmers in the WAS.

新疆CDM项目的开发状况与前景分析

随着世界经济的进一步发展,能源的需求量持续增加,CO2的排放量还将持续增长.温室气体排放带来的气候变暖问题会进一步加剧。清洁发展机制(CDM)是在《京都议定书》框架下,发达国家与发展中国家就碳减排进行合作的重要机制.发展中国家通过CDM可以获得实现节能减排的资金援助和先进技术,促进国家的经济发展和环境的可持续发展。就新疆CDM项目的发展状况、国际碳市场的前景,以及新疆CDM项目开发存在的问题和解决方法方面进行了探讨。
