A Comparative Study on the Implementation of CDM Projects in India

Since the Clean Development Mechanism(CDM) under the Kyoto Protocol was initiated,China and India have overwhelmingly led other developing countries regarding CDM projects development.A comparative study of the CDM in India and China is conducted as there are many similarities between both India and China with regard to the CDM implementation due to the fact that India is another major developing country with a large population and a potential source of GHG emissions rivaling China in the near future.Through examining the development of and legal issues for CDM projects in India,its experience and lessons regarding developing and managing CDM projects that China can critically learn are discussed.     

国际气候变化科学和评估对中国应对气候变化的启示

科学研究和评估工作推动了国际应对气候变化进程,并加大了各国行动力度。更多的科学证据表明人类活动是造成全球气候变暖的主要原因;气候变化影响、适应和脆弱性研究范围不断扩展和深化,区域甚至次国家级层面的问题受到高度关注;2℃温控目标的实现已然成为共识,政策协调与集成及相关政策在不同领域的协同作用成为研究的热点。未来中国应对气候变化需要在四个方面进一步开展研究和采取行动:1加强不同学科和领域的研究工作,围绕与实现温升控制1.5℃、土地利用、海洋以及城市相关问题开展专题研究。2加强国内绿色低碳转型和国际谈判的战略研究。3构建气候服务体系,以灾害风险管理为抓手,提升气候变化适应水平。4通过构建能源互联网实现能源变革,加快推进国内能源革命和经济发展的低碳转型。     

应对气候变化需以生态文明理念构建全球技术合作体系

气候变化是人类发展过程中遇到的最大全球性环境问题,也是最大的外部性问题。IPCC报告显示,实现本世纪末温度升高不超过2度的目标,需要全球经济和能源系统深度的低碳转型,并在本世纪下半叶达到温室气体的净零排放。应对气候变化因此面临着前所未有的技术创新与合作需求。2015年底达成的《巴黎协定》提出了落实技术开发与转让的长期愿景,主张对气候变化领域的技术创新给予政策和资金支持,使发展中国家在技术周期的早期阶段就能够获取必要的技术,从而为实现全球应对气候变化提供保障。然而,基于工业文明的传统技术创新与合作模式难以满足保护全球气候的技术需求。减缓与适应技术是气候变化挑战下全球命运共同体的公共财富。为保证其足够的供应,必须超越追求私人利益最大化的狭隘,基于生态文明理念构建全球应对气候变化的新型技术合作体系。其核心是:实现多赢的合作目标,遵循"生态人"的合作原则,体现协同的合作内容,基于互信的合作形式,鼓励多元主体的参与,促进合作成果的分享。中国作为新兴发展中大国,对应对气候变化技术国际合作有多元的利益需求。为有效落实《巴黎协定》,亟需以加速国际合作为契机,积极谋划中国应对气候变化技术对外合作的总体方略和具体行动,有针对性地制定与发达国家、其他发展中国家及欠发达国家间优势互补的合作计划,探索并引导"南-北-南"三方技术合作等新形式。     

中国参与国际气候治理30年回顾

从20世纪90年代至今的三十年间,中国作为国际气候治理中的关键行为体,在气候治理进程中经历了四个阶段,从审慎的参与者到积极贡献者和引领者,其理念、行动和角色的变迁深刻影响了国际气候治理格局。第一,理念与原则上,在坚持“共区”原则下的发达国家和发展中国家二元划分的基础上,推动国际气候治理的公正转型;第二,意愿与行动上,中国不断加强对国际气候谈判、公约履行、治理方案提供等内容的参与,采取有力度的气候行动;第三,立场与角色上,从被动谨慎到开放积极,再到引领和贡献。究其根本原因,是整体国家利益、国家实力地位和国家角色等三大因素共同作用的结果,表现为一方面受到《联合国气候变化框架公约》为核心的国际气候制度的塑造和影响,另一方面,随着经济发展和温室气体排放的增加,中国也获得了参与国际气候治理的结构性权力,引领了《巴黎协定》“自下而上”的国际气候制度安排。当前《巴黎协定》已从规则制定转向行动落实,中国在2020年9月庄严向国际社会宣布了2030年前实现碳达峰和2060年前实现碳中和的目标,成立了碳达峰碳中和工作领导小组,并将制定“1+N”政策体系。作为负责任大国,中国提出全球发展倡议,强调要坚持人与自然和谐共生,坚持行动导向,完善全球环境治理,加快绿色低碳转型,实现绿色复苏发展。未来中国将以更积极的姿态引领国际气候治理进程,推动人与自然生命共同体和全球发展命运共同体的构建。     

The Belt and Road Initiative and the 2030 Agenda for Sustainable Development: seeking linkages for global environmental governance

ABSTRACT

Global environmental cooperation serves as an important part in the Chinese ideal of building a Community with a Shared Future for all Human Beings. The report of 19th CPC National Congress indicates that China is committed to proactive mitigation under the Paris Agreement and further participating in global environmental governance under the 2030 Agenda for Sustainable Development, and both of which are largely integrated to the Belt and Road Initiative (BRI). BRI are also closely linked with South–South environmental and climate cooperation proposed by China from previous UN summits. Based on shared ideas, intersected agendas, and compatible governance approaches, BRI and the 2030 Agenda for Sustainable Development grow increasingly relevant and they might form synergies based on increasingly interactive relations. In sum, seeking and intensifying the linkages between BRI and 2030 sustainable development goals (SDGs) could address global environmental governance deficits and enhance cooperation among nations.     

Climate capacity:the measurement for adaptation to climate change

This article proposed the concept of"climate capacity"as a way of measuring human’s adaptiveness to climate change.This article also focused on the related concepts like ecological carrying capacity,water resources carrying capacity,land carrying capacity as well as population carrying capacity.The concept of climate capacity was articulated against a background of global climate and environmental change.Essentially,China’s efforts to adapt to climate change was a matter of improving climate capacity,which is the ecosystem as well as the frequency,the intensity and the scale of human’s social activities that the climatic resources of a particular geographic area were supposed to support.The climate capacity has two components.One is the natural climate capacity,which includes temperature,sunlight,precipitation,extreme climatic events,etc.The other is the derived climate capacity,which includes water resources,land resources,ecological systems,climatic risks,etc.The climate capacity can be developed or be transferred between regions by taking engineering,technology or regime-based adaptive measures.However,these adaptive measures must be implemented under the principle of economic rationalism,ecological integrity,climate protection,and social justice.It is expected that by combining the climate capacity and its threshold value with the assessment of climate change risks,we are able to predict the optimal population carrying capacity and the scale of socioeconomic development,and furthermore,provide policy support for the socioeconomic development strategy and adaptive planning.In the regions with high climate capacity,there is a symbiotic relationship between adaptation and socioeconomic development.But,in the regions with limited climate capacity,irrational development may further damage the environment.Taking the Yangtze River delta,a region with high climate capacity,and a region of Ningxia,a region with limited climate capacity,as illustrative examples,the authors of this article analyzed the policy implications of climate capacity and further made suggestions on the problems of capacitylimited adaptation and development-driven adaptation.This article argued that the concept of climate capacity can not only be used as an analytical instrument of climate change economics,but also it can provide research support for planning regional adaptation and development with climate change impact and risk assessments.     

Beyond Counting Climate Consensus

Several studies have been using quantified consensus within climate science as an argument to foster climate policy. Recent efforts to communicate such scientific consensus attained a high public profile but it is doubtful if they can be regarded successful. We argue that repeated efforts to shore up the scientific consensus on minimalist claims such as “humans cause global warming” are distractions from more urgent matters of knowledge, values, policy framing and public engagement. Such efforts to force policy progress through communicating scientific consensus misunderstand the relationship between scientific knowledge, publics and policymakers. More important is to focus on genuinely controversial issues within climate policy debates where expertise might play a facilitating role. Mobilizing expertise in policy debates calls for judgment, context and attention to diversity, rather than deferring to formal quantifications of narrowly scientific claims.     

Governing China’s Coal Challenge: Changing Public Policy,Debate and Advocacy

This paper examines the nexus of coal–government–society relations in present-day China using a governmentality approach to explore the interactions between policy change, “crisis” management and social action. It outlines the noticeable shift in government rationalities and communication regarding the coal industry in recent years. It then frames this shift within the broader context of government–society relations focusing on public debate regarding the calamitous nature of China’s air pollution and its filtering via the censorship apparatus of the Communist Party-state. Finally, it shows how problems relating to coal extraction and combustion have been taken up at the level of grass-roots protest and philanthropic advocacy. An examination of such activism illustrates the crucial role played by digital media networks in sparking debate on coal-related environmental and health crises, and in pushing an authoritarian government to change national coal and other policies in order to maintain social and political stability.     

气候变化研究的中国知识贡献及其影响局限

气候变化知识的不断深化和积累是全球气候治理的基础。政府间气候变化专门委员会(IPCC)邀请全球有代表性的科学家,通过分析评估国际上正式发表的文献,提供关于全球气候变化科学进展的最新认识结论。本文基于文献计量学,通过统计中国在气候变化十大重要领域的科技成果产出量和影响力、中国政府和科学家对IPCC评估报告的参与以及中国大陆引文在IPCC第五次评估报告中的贡献,分析了中国对全球气候变化知识的贡献与局限。结果表明:近十年来,中国在气候变化大多数领域的科技成果产出量已居全球第二或第三位,但在海洋与气候变化、适应气候变化和全球气候治理领域的国际论文量明显落后;与美国和英国相比,中国气候变化科技成果的各类影响力指标明显偏低;中国对IPCC评估报告的参与度和影响力在不断提升,中国积极组织相关机构和专家参与IPCC评估工作,对全球气候治理起到了重要的科学支撑作用;但从IPCC第五次评估报告中国大陆引文的角度看,中国贡献仍整体偏弱,中国大陆引文的贡献呈领域分布不均衡,优势领域少,成果影响面窄的特点。与科学基础领域相比,中国在影响和适应、减缓和国际合作领域的科学贡献更弱,对全球视角关注不够,但中国大陆引文总体的国际科学合作活跃度较高。后巴黎时代,中国需要更加面向国家需求、气候公约和《巴黎协定》目标以及国际气候变化科技前沿,加强全球视野和原始创新,突出中国优势和特色,使气候变化的中国研究成果更多支撑全球气候治理进程的推进。     

IPCC的成立、机制、影响及争议

通过对IPCC成立背景、工作机制、主要报告与影响、有关争议的研究,特别是有关历史背景和第六次评估报告的进展,提出对中国开展气候变化评估的启示建议,供中国相关工作参考。对IPCC成立历史背景的研究发现,在科学家和国际组织的持续推动下,气候变化越来越得到各国政府的重视,为避免独立专家组可能带来的激进环保主义倾向,1988年成立了政府间气候变化专门委员会(IPCC),将专家纳入到政府间框架下专门开展气候变化评估,提供关于气候变化的权威信息,并遵循科学家与政府一致同意方才发布报告的原则开展工作。IPCC通过组织会员国推荐的志愿专家开展评估,建立了由主席团、工作组构成的专家评估团队以及支持主席团政务工作的秘书处、支持工作组的技术支持组,按照建立组织与程序、确定评估范围与专家、编制与审稿、批准与发布等四个环节开展工作。自1990年以来已经发布了五次评估报告,为《联合国气候变化框架公约》(UNFCCC)、《京都议定书》《巴黎协定》等协议的达成提供了科学依据,目前正在开展第六次评估,将重点面向2023年UNFCCC全球盘点。虽然IPCC在工作审查程序、行政管理效率、政府批准决策者摘要等方面有一些争议,但工作总体上是成功的,并在2010年进行了改革优化,受到科学界和国际组织的承认和拥护。从IPCC的经验来看,积极寻找和达成共识是科学与政治决策协同合作的核心要素,未来气候评估将更加重视科学与政策的联系以及跨学科、跨领域、技术驱动和不确定性问题,针对复杂系统的科学评估需要不断完善相应管理制度,中国气候评估也需要积极响应国际进展,突出特色与重点。     

Pros and cons of climate change in China

Climate change strongly affected the structure and functions of natural ecosystems,e.g.the vegetation productivity decreased in the Northeast permafrost region due to the higher temperature and less precipitation,whereas in the Tibetan Plateau,the vegetation productivity increased,owing to the improved thermal resource.Climate change led to reduced precipitation in North and Northeast China and thus the reduced surface runoff.The public needs for energy were changed because of climate change,e.g.the shorter heating period in winter.Climate change profoundly influenced human health,pathophoresis and major projects by increasing extreme events,including frequency and magnitude,and causing more serious water shortage.Under the background of climate change,although the improved thermal resources can be helpful for extending the crop growth period,more extreme events may resulted in more instability in agricultural productivity.Not only did climate change indirectly affect the secondary and tertiary industries through the impacts on agriculture and natural resources,but also climate change mitigation measures,such as carbon tax,tariff and trading,had extensive and profound influences on the socioeconomic system.Further analysis indicated that the impact of climate change presented significant regional differences.The impact had its pros and cons,while the advantages outweighed the disadvantages.Based on the above analysis on the impacts of climate change,we put forward suggestions on coping with climate change.First,scientifically dealing with climate change will need to seek advantages while avoiding the disadvantages of climate change in order to achieve the orderly adaptation to climate change,which is characterized with"Overall best,long-term benefit."Second,quantitative adaptation should be given more attention,e.g.proposing operational schemes and predictable goals and using uncertainty analysis on adaptation measures.Third,more active coping strategy should be adopted to enhance China's future comprehensive competitiveness.The strategies include but are not limited to gradually adjusting the industrial structure,intensifying the research and development(RD)of emission reduction technology and actively responding to the influence of carbon tax,tariff and trading on socioeconomic development in China.
