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

This study presents three scenarios for Chongqing's energy consumption and related CO2 emissions up to 2020, which includes basic development scenario, macro-policy control development scenario and low carbon development scenario. It explains the crucial technologies for Chongqing city as it leaves a business-as-usual trajectory and embarks on a low carbon pathway. A major finding from the scenario analysis is that low carbon and energy-saving policies can dramatically improve Chongqing's position. Under the low carbon scenario, several suggestions for policy making are proposed. This dynamic low-carbon model would benefit from the allocation of decision-making powers in the areas of regulation, policy-making and planning for low carbon development.

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.

Abstract: Threatened by the huge pressure caused by climate change, low-carbon cities have become an inevitable part of urban evolution. It is essential to evaluate urban low-carbon development levels to smoothly promote the construction of low-carbon cities. This paper proposes an evaluation index system for urban low-carbon development from the points of view of economic development and social progress, energy structure and usage efficiency, living consumption, and development surroundings. A weighted sum model was also established. Selecting 12 typical Chinese cities as cases studies, an integrated evaluation was conducted based on the index system and the assessment model. The development speed and limiting factors of different cities were also analyzed. The 12 cities were ultimately classified into three groups in terms of their low-carbon development patterns by integrating all of the analysis results. Furthermore, suitable regulation and management for different patterns were suggested. This study both aids in assessing the executive effect of low-carbon city construction and helps to determine existing problems and suggest effective solutions.

Centre for Sustainable Energy Technologies, The University of Nottingham Ningbo China 27th to 28th October 2012 Ningbo, Zhejiang, China The building sector is one of the highest energy consuming sectors in China accounting for about 30% of total energy usage and also contributes to a significant proportion of pollutant emissions in China. Meanwhile, building construction activities are contributing significantly towards China's economic growth and infrastructure development under the current urbanisation programme. It is estimated that half of the world's buildings being constructed between now and 2020 are expected to be built in China and if nothing is done to control the upward energy trend, building-related energy consumption could double and have a devastating effect on the environment and the economy as a whole. The objective of this international symposium is therefore to provide a forum for academics, government officials, researchers and practitioners to present and discuss recent research and demonstration projects related to low carbon buildings in China. The event will feature well known international experts in this field as Keynote speakers.

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.[...]

October 19-21, Guangzhou baiyun international convention center LCES-2012 will continue to provide an alternative platform to other global conferences in related to climate change and environment protection. We will focus more on practical perspectives on green economy, promotion of sustainable or renewable energy, and exhibit technical resolutions to solve and predict the existing issues. Through the massive operations on comprehensive topics related low carbon economy and industries, we hope the summit can provide best information to exchange channels for all endeavors on low carbon fields who are working on controlling global climate changes from policy makers, NGO leaders, economists, investors, engineers, scientists, industrial leaders, carbon traders, brokers, clean emerge producers, energy consumers, toward daily low carbon life practitioners and advocators etc. Thus, LCES-2012 can provide help our society and humanity with unprecedented impacts on the world sustainable development, new economy growth and renewable energy innovation to commercialization.

A group of government officials from China traveled on a study tour in the United States last week. The tour, hosted by the World Resources Institute, focused on low carbon development. The delegation was led by Director General Su Wei of the Department of Climate Change from China's National Development and Reform Commission (NDRC), who is China's chief negotiator on climate change and a key decision maker for low-carbon development initiatives.

Economics, Politics and Public Policy in East Asia and the Pacific [En ligne] Consulté le 23/08/2012 http://www.eastasiaforum.org While many Chinese pundits and scholars are applauding for China's Twelfth Five-Year Plan (2011-2015) as a milestone for China's green revolution, the country's march to low energy consumption and low carbon economy is not going to be a smooth or straight one. China's five-year plans, albeit strategically sound, are not likely to change the short- and medium-term energy and climate landscapes. Challenges will remain [...]

Full Text available. As some of the most rapidly urbanizing places in the world, China's cities have a unique relationship with global climate change. 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.

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".

Thématique n° 2 [ScienceDirect, via Biblio-SHS] Auteur : Jing Wu, Joseph Gyourko, Yongheng Deng Paru dans : Regional Science and Urban Economics, Volume 42, Issue 3, May 2012, Pages 531-543, Special Section on Asian Real Estate Market Abstract High and rising prices in Chinese housing markets have attracted global attention. Price-to-rent ratios in Beijing and seven other large markets across the country have increased by 30% to 70% since the beginning of 2007. Current price-to-rent ratios imply very low user costs of no more than 2%-3% of house value. Very high expected capital gains appear necessary to justify such low user costs of owning. Our calculations suggest that even modest declines in expected appreciation would lead to large price declines of over 40% in markets such as Beijing, absent offsetting rent increases or other countervailing factors. Price-to-income ratios also are at their highest levels ever in Beijing and select other markets, but urban income growth has outpaced price appreciation in major markets off the coast. Much of the increase in prices is occurring in land values. Using data from the local land auction market in Beijing, we are able to produce a constant quality land price index for that city. Real, constant quality land values have increased by nearly 800% since the first quarter of 2003, with half that rise occurring over the past two years. State-owned enterprises controlled by the central government have played an important role in this increase, as our analysis shows they paid 27% more than other bidders for an otherwise equivalent land parcel.

UCI delegation participated in first annual NCF summit in Paris 25/05/2012 The Chinese delegation takes a group photo with Lady Barbara, Judge, Chairman of the UK Pension Protection Fund. The first annual New Cities Foundation (NCF) Summit was held in Paris on May 14-16. The summit brought together more than 500 urban policy makers and thought leaders to a three-day conference on global urbanization, with China as one of the core focuses. The mayor of Paris delivered a welcome speech. Other speakers including Gregor Robertson, Mayor of Vancouver; Ron Huldai, Mayor of Tel Aviv; Khalifa Sall, Mayor of Dakar; Greg Clark, UK Minister of State for Decentralisation and Cities; as well as the CEOs of General Motors, Ericsson, Cisco, and Suez gas. The Urban China Initiative (UCI), a partner of the NCF, assisted in organizing the summit by inviting and organizing 16 government delegates, enterprise leaders, and academics from China, as well as designing the plenary session "A Closer Look at Urban China: Towards the Urban Billion." Chinese delegates shared their insights as speakers at plenary and breakout sessions, including: "Securing Investments for the Urban Century: How do we Pay for the Urban Boom," which featured Li Dongming, General Manager of the Urban Fund at China Development Bank Capital, as a speaker. "Hard and Software City," which featured Jonathan Woetzel, Co-Chair of the Urban China Initiative, Senior Director at McKinsey & Co., as a speaker.

Chen, Binkai; Lu, Ming; Zhong, Ninghua In: Global COE Hi-Stat Discussion Paper Series, February 2012 Abstract This paper provides a new explanation for China's extremely low consumption-to-GDP ratio, highlighting the constraints of the "household registration system" (Hukou) on China's household consumption. Our baseline results show that the consumption of migrants without an urban Hukou is 30.7% lower than that of urban residents. Moreover, consumption heterogeneity cannot be explained by migration effects, culture, social norms, habits or some other forms of household heterogeneity. Further studies on the composition of household consumption have shown that the gaps are largest in areas such as education and culture, durable goods and health. As both the number and income level of migrants are rising, the constraining effects of Hukou on household consumption will continue to increase.

The story is about 'Integrated Fish Farming', using traditional methods that have been adapted to modern circumstances, and opportunities to apply these as a low ecological footprint fish farming model.

The rapid growth of the Chinese economy has resulted in great pressure on energy consumption, especially the energy intensive sector - the industrial sector. To achieve sustainable development, China has to consider how to promote energy efficiency to meet the demand of Chinese rapid economic growth, as the energy efficiency of China is relatively low. Meanwhile, the appeal of energy saving and emission reduction has been made by the Chinese central government. Therefore, it is important to evaluate the energy efficiency of industrial sector in China and to assess efficiency development probabilities. The framework of total factor energy efficiency index is adopted to determine the discrepancy of energy efficiency in Chinese industrial sector based on the provincial statistical data of industrial enterprises above designated size in 30 provinces from 2005 to 2009, with gross industrial output as the output value and energy consumption, average remaining balance of capital assets and average amount of working force as the input values. Besides, in considerate of the regional divide of China, namely eastern, central, and western, and economic development differences in each region, energy efficiency of each region is also analysed in this paper. The results show that there is room for China to improve its energy efficiency, especially western provinces which have large amount of energy input excess. Generally speaking, insufficient technological investment and fail of reaching best scale of manufacture are two factors preventing China from energy efficiency promotion. Based on our findings, some policy implications on the improvement of energy efficiency, particularly for economically underdeveloped regions in China, are also discussed.

DOI: http://dx.doi.org.gate3.inist.fr/10.1016/j.landusepol.2011.11.010 [ScienceDirect, via Biblio-SHS] Auteur : Jing Wang et al. Paru dans : Land Use Policy, Volume 29, Issue 4, October 2012, Pages 737-749 Abstract China has extremely scarce land resources compared to the world average. There is an urgent need for studies of the current situation and the trends in land-use change and assessment of the performance of land policies in China. Assessment of land-use change has long been hindered by a lack of accurate and reliable data. This paper uses the data obtained from the national land surveys of 1996 and land-use change surveys from 1997 to 2008, to analyze changes in land use and the policy dimension driving forces related to the changes, especially cultivated land, forestry land, grassland, as well as developed land. The aim of this analysis will be to derive the physical, social and economical driving forces of those changes to grasp the trends in land-use change and the effects of land policies and to formulate strategies for the protection and sustainable use of agricultural land. The results indicate that, although the overall change in land use was not large, cultivated land was significantly reduced and developed land rapidly increased. A great deal of high quality cultivated land was changed to developed land and low quality cultivated land generated from unused land, which has resulted in a serious threat to food supplies in China. Predictions using the methods of linear extrapolation and a BP neural network indicate that it is impossible to keep to a target of 0.12 billion hectares of cultivated land in the future under the mode of economic development used between 1996 and 2008. The results also indicate that the implementation of the laws and regulations about controlling the developed land and preserving cultivated land had significant effects on changes in land use, especially cultivated land and developed land. The results sugges

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)."
