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.     

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.     

清洁发展机制与中国碳排放交易市场的构建

清洁发展机制是《京都议定书》创设的实现全球碳减排目标的三大灵活机制之一,为我国的可持续发展作出了重大贡献,但其在我国运行中存在的问题也对我国参与国际碳市场和构建国内碳市场带来了风险与障碍.针对于此,本文对中国清洁发展机制项目的类型、数量、注册、签发等情况进行对比,发现我国虽然项目众多,但发展极不平衡.在此基础上,分析了中国清洁发展机制存在的主要问题,包括法律保障机制缺失,项目减排潜力发挥不充分,缺乏对转让技术的科学评估等.然后,通过介绍国际碳排放交易市场发展的不确定性和在2012年“后京都时期”的发展趋势,揭示了中国在这一过程中所承担的项目投资减少、成本增加等市场风险以及“碳泄漏”等环境风险.针对上述问题和风险,本文提出以现有清洁发展机制经验为基础构建中国国内碳排放交易市场的基本思路,即建立以排放交易法律体系为基础,以自愿碳交易市场构建为起点,以完善的监督管理体系为保障的中国碳排放交易机制.     

The Integration and Sustainable Development of Chengdu-Chongqing Urban Agglomeration

Urban Agglomeration is an inevitable outcome of urbanization and industrialization, and a main form of urban development. Based on the analysis of urbanization and urban system situation, this paper will discuss the integration of urban agglomeration development, using the urban area of Cheng （Chengdu）-Yu （Chongqing） Urban agglomeration （CYUA） as a case study. By means of industries, population and spatial integrations, the function, strength and competition of CYUA will be improved and this urban agglomeration will transit from a budding state to a growing and mature one in future. The sustainable development of CYUA will depend on countermeasures, such as accelerating industrialization and urbanization, building a traffic network and express roads, strengthening the ability of self-sufficiency, enlarging the ecological construction and environmental protection, and establishing the synergetic institution of cross districts.     

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.

欧洲能源复兴计划CCS示范项目实施进展与启示

碳捕集与封存(Carbon Capture and Storage,CCS)作为最有前景可有效深度减排的低碳技术之一,在世界范围内受到广泛推行,特别是欧洲,其作为全球CCS技术的先行者,一直在积极推进该项技术工业化进程.2009年,欧盟委员会(European Commission,EC)启动欧洲能源复兴计划(European Energy Programme for Recovery,EEPR),正式批准资助6个全流程CCS示范项目.这6个CCS示范项目囊括了当前所有可行的CO2工业捕集技术,运输方式以及封存方法,本文将对其基本情况和最近进展进行介绍,并重点对欧盟层面的CCS法律法规与此6个项目所在欧盟成员国的CCS技术与政策环境的交互影响进行比对和分析,以进一步系统评述欧洲能源复兴计划CCS示范项目带来的积极成果,包括达成减排目标和气候政策,建立欧洲CCS示范项目网络共享平台,获得CCS技术研发突破等,同时也详细列举了这些项目目前所面临的阻碍与困境,如相关法律政策缺乏执行力,融资困难,公众接受度低,技术成本高等.最后,试探讨欧盟能源复兴计划CCS全流程示范项目实施发展现状对我国未来CCS商业化走向的思索与启示.

Fuel efficiency enhancement of modified diesel engine operated in dual fuel mode using renewable and sustainable fuels

ABSTRACT

Renewable and sustainable fuels for diesel engine applications provide energy protection, overseas exchange saving and address atmospheric and socio-economic concerns. This study presents the investigational work carried out on a single cylinder, four-stroke, direct injection diesel engine operated in dual fuel (DF) mode using renewable and sustainable fuels. In the first phase, a Y-shaped mixing chamber or venture was developed with varied angle facility for gas entry at 30°, 45° and 60°, respectively, to enable homogeneous air and gas mixing. Further effect of different gas and air mixture entry on the DF engine performance was studied. In the next phase of the work, hydrogen flow rate influence on the combustion and emission characteristics of a compression ignition (CI) engine operated in DF mode using diesel, neem oil methyl ester (NeOME) and producer gas has been investigated. During experimentation, hydrogen was mixed in different proportions varied from 3 to 12 l/min (lpm) in step of 3 lpm along with air-producer gas and the mixtures were directly inducted into engine cylinder during suction stroke. Experimental investigation showed that 45° Y-shaped mixing chamber resulted in improved performance with acceptable emission levels. Further, it is observed that investigation showed that at maximum operating conditions and hydrogen flow rate of 9 lpm, Diesel–producer gas and NeOME–producer gas combination showed increased thermal efficiency by 13.2% and 3.8%, respectively, compared to the DF operation without hydrogen addition. Further, it is noticed that hydrogen-enriched producer gas lowers the power derating by 5–10% and increases nitric oxide (NO_x) emissions. However, increased hydrogen addition beyond the 12 lpm leads to sever knocking.
