Thématique n° 2 [ScienceDirect, via Biblio-SHS] Auteur : Lynn Price, Nan Zhou, David Fridleya, Stephanie Ohshitaa, Hongyou Lua,Nina Zhenga, Cecilia Fino-Chen Paru dans : Habitat International, Available online 28 January 2012 Abstract In 2009, China committed to reducing its carbon dioxide intensity (CO2/unit of gross domestic product, GDP) by 40-45% by 2020 from a s2005 baseline and in March 2011, China's 12th Five-Year Plan established a carbon intensity reduction goal of 17% between 2011 and 2015. The National Development and Reform Commission (NDRC) of China then established a Low Carbon City policy and announced the selection of 5 provinces and 8 cities to pilot the low carbon development work. How to determine if a city or province is "low carbon" has not been defined by the Chinese government. Macro-level indicators of low carbon development, such as energy use or CO2 emissions per unit of GDP or per capita may be too aggregated to be meaningful measurements of whether a city or province is truly "low carbon". Instead, indicators based on energy end-use sectors (industry, residential, commercial, transport, electric power) offer a better approach for defining "low carbon" and for taking action to reduce energy-related carbon emissions. This report presents and tests a methodology for the development of a low carbon indicator system at the provincial and city level, providing initial results for an end-use low carbon indicator system, based on data available at the provincial and municipal levels. The report begins with a discussion of macro-level indicators that are typically used for inter-city, regional, or inter-country comparisons. It then turns to a discussion of the methodology used to develop a more robust low carbon indicator for China. The report presents the results of this indicator with examples for 6 selected provinces and cities in China (Beijing, Shanghai, Shanxi, Shandong, Guangdong, and Hubei). The repor

The economies found in Chinese cities are extremely resource and energy intensive; as a result, they produce significant levels of greenhouse gas (GHG) emissions. This article provides comprehensive and detailed emissions inventories for Shanghai, Beijing, and Tianjin, which were found to be responsible for 12.8, 10.7, and 11.9 tonnes of carbon dioxide equivalent per capita (t CO2-eq/capita), respectively, in 2006. The majority of emissions were from electricity production, heating and industrial fuel use, and ground transportation. The prevalence of coal in the energy supply mix (including up to 98% in Tianjin) was a fundamental cause of high energy emissions. Non-energy emissions from industrial processes were also significant, including emissions from cement and steel production. The GHG inventories for Shanghai, Beijing, and Tianjin point to sectors requiring the most attention in terms of low-carbon growth. Compared to ten other global cities, Chinese cities are among the highest per capita emitters, alluding to the important challenge China faces of reducing emissions while improving the quality of life for urban residents. Accordingly, this article concludes with a discussion of the opportunities and issues concerning low-carbon growth in China, including the potential for renewable energy and the difficulties associated with emissions relocation and policy adoption.

China's carbon markets push: Huge potential, but daunting challenges A domestic cap-and-trade system could more effectively curb emissions than command-and-control, a new report from SEI and FORES shows, but the process is still in its infancy. China observers have rightfully called attention to the country's new interest in market-based approaches to reducing the energy- and carbon-intensity of its economy. It is a major policy shift, and given that China is the world's top carbon emitter, it has potentially huge implications for global efforts to slow climate change. But can carbon trading succeed without a mature free-market economy? That is a key question raised in the report, China's Carbon Emission Trading: An Overview of Current Development, by SEI's Guoyi Han, Marie Olsson and Karl Hallding, and David Lunsford, founder of the Hong Kong-based consultancy Energy Environment Solutions. The report was released today in Brussels at a seminar with several Members of the European Parliament. "If China's carbon markets experiment succeeds, it could be decisive," says Martin Ådahl, director of FORES, which co-sponsored the report. "Not only could it slow China's rapid emissions growth, but it would be an important step towards global carbon pricing. A great deal is at stake."

Xing [et al.] Paru dans : Procedia Environmental Sciences, Volume 13, 2012, Pages 1143-1148 18th Biennial ISEM Conference on Ecological Modelling for Global Change and Coupled Human and Natural System Abstract It is undoubted that low-carbon city has become a vital development trend for Chinese cities in the new century. Many Chinese cities have been devoted to the upsurge of low-carbon city construction in recent years. Focusing on these problems - What measures has been adopted to construct low-carbon city in China? How is the effect of low-carbon city construction? Are there some issues needing attention in the future - this paper summarizes the situation of low-carbon city development in China and clarifies a few viewpoints that need be paid attention to in the subsequent development. It is expected that the discussion in this paper can help promote the construction of low-carbon city in China.

Zhang Chun Wang Haotong August 03, 2012 China's low-carbon city programmes are doing well on public awareness, but an NGO survey finds little evidence of greener habits. Only a small proportion of people in China's low-carbon pilot cities are living "low-carbon lives" in spite of widespread knowledge of the green agenda, a year-long survey of household energy consumption carried out by Beijing-based NGO Green Beagle suggests. The study of habits in eight Chinese cities identified as green leaders by China's top economic planning body, the National Development and Reform Commission, involved 3,200 questionnaires and interviews with three to five households in different income brackets in each region. The NGO wanted to find out if inhabitants of these places had heard about "low-carbon" lifestyles and whether they were making efforts to reduce their own environmental footprint through their daily choices. Under the "low-carbon" pilot scheme, which launched in 2010, the eight cities - Tianjin, Chongqing, Shenzhen, Xiamen, Hangzhou, Nanchang, Guiyang and Baoding - are trying to find ways of reducing carbon emissions while continuing to grow economically (Beijing and Shanghai were added to the list in 2011, but are treated as a separate category). Five provinces are charged with the same task: Guangdong, Liaoning, Hubei, Shanxi and Yunnan. If they perform well, they will be treated as an example for the rest of the country.[...]

Abstract The large cities such as London, New York and Shanghai are tended to create lots of employment opportunities, but per capita carbon emissions are huge. It is a vital problem about how to provide enough employment opportunities and reduce per capita carbon emissions during the process of urbanization in China. The main of this article think "the Zipf-type city system in area "can achieve the goal of "efficiency and low carbine".

Local level actions can also assist in proving the effectiveness of new policies or initiatives by demonstrating them at a smaller scale. It is often also shown that innovative policies or practices can be relatively easily implemented at the local level because of the reduced scale and the possibility of exemption from some national legislative bureaucracy. Following success at the local level, the pilot policies or practices could be replicated to other localities or expanded to a national program. For example, China's Top-1000 Enterprise Program was drawn upon the successful experience from a demonstration program implemented in two steel mills in Shandong province that was modeled after the voluntary agreements program in The Netherlands (Price et al. 2003)."
