合成氨副产CO2气的回收与利用

CO2是《京都议定书》要求减排的6种温室气体之一,《京都议定书》还确立了有助于发展中国家获得资金和先进技术的清洁发展机制（CDM）。本文结合实际工程案例,介绍了合成氨副产CO2气的回收和利用方法,为我国氮肥行业申请CDM项目资助,回收利用CO2,减少CO2排放提供技术参考。     

为完成《京都议定书》减排任务日本大买中国排放权

温室气体排放权交易是根据旨在控制全球气候变暧的《京都议定书》上规定的清洁发展机制 (CDM)开展的业务。《京都议定书》的清洁发展机制规定,发达国家通过帮助发展中国家削减温室气体,所削减的部分可以作为自身的排放权使用。《京都议定书》于2005年2月正式生效,日本和中国都是缔约国。     

清洁发展机制在全球范围及我国的进展概述

清洁发展机制（Clean Development Mechanism,CDM）是《京都议定书》框架下三种灵活减排机制中惟一连接发达国家和发展中国家的温室气体减排机制,自2004年11月18日全球第一个CDM项目注册成功至今短短4年时间内,CDM已得到广泛认可并在国内外范围内的项目市场迅速发展。     

内蒙古清洁发展机制（CDM）项目现状分析及对策

清洁发展机制（Clean Development Mechanism,简称CDM）是《京都议定书》规定的3种温室气体减排途径之一,也是发展中国家唯一的参与温室气体减排的机制。本文以我国现阶段CDM项目发展现状为背景,具体针对内蒙古CDM项目现状及存在的问题（截至2010年9月7日）展开分析,提出内蒙古发展CDM项目的解决对策。

辽宁清洁发展机制（CDM）项目开发现状分析

清洁发展机制（CDM）是《京都议定书》确定的,是发达国家通过提供资金和技术的方式,与发展中国家进行合作实现温室气体减排的一种合作机制。辽宁是工业大省,节能减排潜力巨大,具有良好的CDM项目发展潜力。总结了辽宁CDM项目开发现状,分析了CDM项目开发中存在的问题,并提出相应的对策和建议。     

清洁发展机制对我国节能减排的作用

清洁发展机制（CDM）是《京都议定书》发达国家和发展中国家就减排温室气体进行交易的合作机制。我国“十一五”规划《纲要》提出了节能减排的目标,而我国还是一个发展中国家,要实现节能减排面临很多的困难。CDM项目大部分是与提高能效和开发利用新能源直接有关,因此,CDM能为此提供一定的推动力,能够促进我国的节能减排。文章分析了当前我国节能减排面临的困难,探讨了CDM在我国节能减排所起的作用,提出我国对积极开发CDM项目应采取的相应对策。     

建设全国性碳排放交易中心发展CDM项目

清洁发展机制（CDM）是《京都议定书》提出的在全球范围内实施温室气体减排的重要机制,是发达国家与发展中国家基于项目的合作形式,是一种“双赢”政策。文章首先简述了清洁发展机制及与碳交易市场的情况,接着论述了清洁发展机制在中国的发展,提出建设全国的碳排放交易中心及意义,从而促进CDM在中国的发展。     

浅谈参与清洁发展机制的意义

清洁发展机制,是《京都议定书》中引入的三个灵活履约机制之一。由于发达国家减排温室气体的成本是发展中国家的几倍甚至几十倍。发达国家因此通过在发展中国家实施具有温室气体减排效果的项目,把项目所产生的温室气体减少的排放量作为履行《京都议定书》所规定的一部分义务。对清洁生产机制的理论和意义进行了简要的阐述和说明。     

中国CDM项目商机初现

经过国际社会共同努力，《联合国气候变化框架公约》缔约国签订的《京都议定书》在2005年2月16日正式生效，而《京都议定书》所引入的清洁发展机制（CDM）、排放贸易（ET）和联合履约（JI）3个灵活机制也随之进入了公众视线。     

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。     

中国CDM市场现状分析和管制建议

《京都议定书》的生效、CDM项目活动在全球的广泛开展为发展中国家寻求经济和环境的共赢发展带来了前所未有的机遇,中国的经济正处于高速发展中,在未来的国际CDM市场中必将扮演重要的角色。虽然我国在开发CDM项目、促进温室气体减排方面做出了突出的贡献,但仍然存在项目分布不合理、信息不对称、偏离方法学等明显问题。面对未来可以预见的国际环境压力,我们应当加强管制,充分利用好CDM的机遇。在借鉴印度、巴西等其他发展中国家的做法、总结自身经验和不足的基础上,提出CDM项目的管制建议,在政策引导、宣传培训、项目选择和方法学应用等方面调整CDM项目的发展策略,为我国的参与CDM带来更为巨大的商机和活力。     

清洁发展机制(CDM)实践及理论研究进展

清洁发展机制(CDM)是《京都议定书》(KP)中规定的发达国家与发展中国家之间的温室气体减排合作方式。随着2005年2月26日KP的生效,CDM实施活动在全球范围内开始全面展开。中国被公认为是温室气体减排潜力最大的国家,具有广阔的开展CDM合作的前景。为了能配合国内CDM的实践活动,本文在大量文献及重要文件研究基础上,总结了CDM诞生10年来的实践及理论发展情况,并分析了CDM今后的发展趋势。     

The impact of the Clean Development Mechanism on developing countries’ commitment to mitigate climate change and its implications for the future

The objective of this paper is to examine the mitigation of climate change using the Clean Development Mechanism (CDM) from the perspective of developing countries. The effects of the CDM on developing countries’ efforts to reduce greenhouse gases (GHGs) pledged under the Paris Agreement (United Nations Framework Convention on Climate Change [UNFCCC], 21st Conference of the Parties, Paris, France) are investigated. Data analysis reveals that the intensive hosting of CDM projects and the resultant higher marginal abatement costs led to fewer efforts by developing countries to mitigate climate change. A theoretical model from the literature of “low-hanging fruits” is applied to determine if rising prices of the CDM can be expected in the future. The results indicate that the benefits for developing countries must increase so as to keep the CDM attractive for them in an environment where they also have reduction commitments. To further ensure the effectiveness of the CDM under the Paris Agreement, policy should ensure that developing countries actually charge higher prices and, at the same time, contribute adequately to the global goal of GHG reductions. To this end, developing countries should be permitted to demand benefits that lie outside the current scope of the CDM, and non-compliance with their climate targets should also be sanctioned. In addition, fostering sustainable development should become more attractive for developed countries without the CDM, e.g., through sustainability labels, so as to reduce the trade-off for developing countries between the benefits of the CDM and compliance with their commitments to mitigate climate change.

     

The elephant in the room – A comparative study of uncertainties in carbon offsets

The clean development mechanism (CDM) is a flexible mechanism under the Kyoto Protocol, which makes it possible for developed countries to offset their emissions of greenhouse gases through investing in climate change mitigation projects in developing countries. When the mitigation benefit of a CDM project is quantified, measurable uncertainties arise that can be minimised using established statistical methods. In addition, some unmeasurable uncertainties arise, such as the rebound effect of demand-side energy efficiency projects. Many project types related to land use, land-use change and forestry (LULUCF) have been excluded from the CDM in part because of the high degree of statistical uncertainty in measurements of the carbon sink and risk of non-permanence. However, recent discussions within the United Nations Framework Convention on Climate Change (UNFCCC) have opened up for the possibility of including more LULUCF activities in the future. In the light of this discussion, we highlight different aspects of uncertainties in LULUCF projects (e.g. the risk of non-permanence and the size of the carbon sink) in relation to other CDM project categories such as renewables and demand-side energy efficiency. We quantify the uncertainties, compare the magnitudes of the uncertainties in different project categories and conclude that uncertainties could be just as significant in CDM project categories such as renewables as in LULUCF projects. The CDM is a useful way of including and engaging developing countries in climate change mitigation and could be a good source of financial support for LULUCF mitigation activities. Given their enormous mitigation potential, we argue that additional LULUCF activities should be included in the CDM and other future climate policy instruments. Furthermore, we note that Nationally Appropriate Mitigation Actions (NAMAs) are currently being submitted to the UNFCCC by developing countries. Unfortunately, the under-representation of LULUCF in comparison to its potential is evident in the NAMAs submitted so far, just as it has been in the CDM. Capacity building under the CDM may influence NAMAs and there is a risk of transferring the view on uncertainties to NAMAs.     

Reforming the CDM for sustainable development: lessons learned and policy futures

The Clean Development Mechanism (CDM) has successfully demonstrated that market-based mechanisms can achieve some cost effective emissions reductions in developing countries. However the distribution of CDM projects has been extremely uneven across countries and regions, and a few technologies and sectors have dominated the early stages of CDM experience. This has caused some to question whether the CDM has fallen short of its potential in contributing to sustainable development. We review the broad patterns of CDM project approvals and evaluate 10 CDM projects according to their sustainability benefits. The difficulty of defining “sustainable development” and the process of defining criteria by individual non-Annex 1 governments has meant that sustainable development concerns have been marginalized in some countries. Given these observed limitations, we present possible CDM policy futures, focusing on the main proposals for a post-2012 climate regime. Five options for enhancing the sustainable development benefits in the CDM are discussed, including proactive approaches to favour eligibility of emission reduction projects which ensure such co-benefits.
