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.

[ScienceDirect, via Biblio-SHS] Auteur : Wilco Chan Paru dans : International Journal of Hospitality Management, Volume 31, Issue 4, December 2012, Pages 1130-1142 Abstract Achieving effective and objective energy benchmarking for hotels is integral in fostering the sustainable development of the lodging sector. In this work, we reveal the major and minor streams of hotel energy benchmarking and ascertain that the most popular approach in benchmarking is normalized energy use intensity (EUI) based on floor level. Previous efforts to establish EUI indicators using subsystem average, data envelopment analysis (DEA), and regression technique are also studied. We propose that hotel energy benchmarking based on floor area is useful from the top-down management perspective. However, on a practical perspective, energy benchmarking based on facilities should be the first priority for hotel management or owners. Compared with the general energy benchmarking in the building sector, we find that the hotel sector lags behind in the adoption of computer modeling for benchmarking. By conducting in-depth interviews with hotel engineers, system designers, and professors to identify the challenges faced by current hotel energy benchmarking, we gain deeper insights on the development of hotel energy benchmarking that reflect the current situation in China. A taxonomical approach focusing on four directions of hotel energy benchmarking is thus proposed. By coordinating with various types of stakeholders and implementing the proposed development plan, the local Construction Ministry, Tourism Bureau, and Energy Improvement Office can realize this conceptual hotel energy benchmarking in China.

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.

[ScienceDirect, via Biblio-SHS] Auteur : Guiwen Liu, Zezhou Wu, Mingming Hu Paru dans : Energy Procedia, Volume 14, 2012, Pages 1925-1930 Abstract Around 30% of the national energy consumption in China can be attributed to buildings, of which one-fifth is consumed within public buildings. In recent time, public buildings have been reckoned as the dominant objects for conducting energy efficient management. In order to obtain valuable information for the assessment of energy consumption status, an investigation was conducted in Chongqing - the youngest, largest and most dynamic municipal in China. A number of public buildings, including 28 governmental office buildings, 15 emporiums and 5 hotels, were selected for the investigation from the aspect of energy cost. Based on the collected data of electricity, water and gas, the characteristics of the energy consumption in each type of the public buildings are discussed, and the energy management in each type of public buildings is compared. 2011 2nd International Conference on Advances in Energy Engineering (ICAEE)

With rapid economy growth, building energy consumption in China has been gradually increased. The energy consumption and indoor environmental quality of 51 office buildings in Hainan Province, a hot and humid area, were studied through collection of verified data in site visits and field tests. The result revealed that, electricity accounted for 99.79% of the total energy consumption, natural gas 0.17%, and diesel 0.04%. The air conditioning dominated the energy use with a share of 43.18%, equipment in the particular areas 26.90%, equipment in the office rooms 11.95%, lighting system 8.67%, general service system 7.57%, and miscellaneous items 1.73%. Statistical method including six indicators obtained the energy consumption benchmark with upper limit of 98.31 kW·h/m2 and lower limit of 55.26 kW·h/m2. According to ASHRAE standard (comfortable standard) and GB/T 18883-2002 (acceptable standard), the indoor environmental quality of 51 sampled office buildings was classified into three ranks: good, normal and bad. With benchmark of building energy consumption combined with indoor environmental quality, it was found that only 3.92% of sampled buildings can be identified as the best performance buildings with low energy consumption and advanced indoor environmental quality, and the buildings classified into normal level accounted for the maximum ratio.

Along with the rapid development of urbanization, the energy problem is increasingly prominent. Based on CES production function and growth function of urbanization, this paper put forward the model of Growth Drag of China's Urbanization Caused by energy, and empirical analysis with the data of China was done. The results showed that the growth drag of energy during urbanization process in China is 0.2692,in other words, because of the restriction of energy, urbanization process declines 0.2692.From the results, the Growth Drag of China's Urbanization Caused by energy is very high. Ensure that energy security supply has become one of the important tasks for our country at present.

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.

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.

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 [...]

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

Residential energy consumption (REC) is the second largest energy use category (10%) in China and urban residents account for 63% of the REC.

In common with other major economic centres in China, Shanghai's energy consumption has been increasing rapidly to support the high growth rate of its economy. To achieve rational, efficient and clean use of energy, together with improved environmental quality within the city, the Shanghai municipal government has decided to expand the supply and utilization of natural gas. Shanghai plans to increase the share of natural gas in its primary energy mix to 7 per cent by 2010, up from 3 per cent in 2005. This increase in natural gas demand has to be matched with a corresponding increase in supply. To date, the Shanghai region has relied on offshore extracted natural gas but this supply is limited due to the size of the reserves. Since 2005, the West-East pipeline has provided an alternative for Shanghai but demands from other regions could reduce the potential for expanding supplies from that source. Since domestic production will not be sufficient to meet demand in the near future, Shanghai is building a liquefied natural gas (LNG) regasification terminal at the Yangshan deep-water port that would allow an additional supply of more than 3 billion cubic meters per year of natural gas. Malaysia has already committed to supply LNG to the Shanghai terminal at a price that is significantly higher than the wholesale "city-gate" price for natural gas transported via pipeline, but still lower than the gas price to end-use consumers. The presence of both an LNG terminal and a transmission pipeline that connects Shanghai to domestic gas-producing regions will create gas-on-gas competition. This study assesses the benefits of introducing such competition to one of China's most advanced cities under various scenarios for demand growth. In this paper, the impact of imported LNG on market concentration in Shanghai's gas market will be analysed using the Herfindahl-Hirschmann index (HHI) and the residual supply index (RSI). Our results show that Shanghai remains a supply-constrained

Abstract This paper links urbanization strategies to changes in land use and associated impacts on rural communities and agro-ecosystems in a rural area of China. Energy, monetary and human time variables as well as information on environmental pressures, have been combined to compare different typologies of households and the metabolism of different patterns of land use from an integrated perspective. The results show that urbanization strategies, aimed at shifting the current land use and at displacing the local population, while increasing the economic efficiency is also associated with an increase in fossil energy consumption and environmental pressure, as well as a reduction of the multifunctional characteristic of the area under investigation. Based on these findings the paper also offers a critical discussion of the Chinese rural development policy arguing that the multifunctionality of rural areas should be taken into account by Chinese policy-makers and planners as a viable strategy to achieve rural development targets. Highlights ► Urbanization strategies in China drive the land use change of rural areas. ► Forced migration decreases rural food self-sufficiency and diversification of risk. ► HEPA patterns have higher economic efficiency and energy intensity than LEPA. ► Rural-urban migrations favor the creation of mono-functional agricultural systems.

A heated debate burns around the topic of waste incineration, the flames of which are stoked when the practice turns mountains of trash into usable energy through a toxic transformation. An article from China Dialogue outlines the practice and politics of garbage-incineration and the use of waste-to-energy technology in China, and how it will continue through the 12th five-year-plan.

DOI : http://dx.doi.org.gate3.inist.fr/10.1016/j.enpol.2012.05.080 [ScienceDirect, via Biblio-SHS] Auteur : Nyakundi M. Michieka, Jerald J. Fletcher Paru dans : Energy Policy, Available online 22 June 2012 Abstract This paper investigates the causal relationship between urban population, real GDP, electricity production and coal consumption in China for the period 1971-2009. Using a vector autoregression framework and a modified version of the Granger (1969) causality test proposed by Toda and Yamamoto (J. Econ. 66 (1995) 225), the results suggest that there is causality running from GDP to coal consumption. The variance decomposition analysis report that urban population and coal affect electricity production variability over the forecast period. We also find that increasing urban population may negatively affect China's GDP over time. Policy measures aimed at influencing GDP could ultimately affect coal consumption. Highlights ► We find Granger Causality running from GDP to coal consumption. ► China can mitigate the adverse environmental effects of coal by altering GDP path. ► We find Granger Causality running from urbanization to electricity production. ► China needs to find other sources of energy to cater for growing electricity demand. ► Increasing urban population may slow economic growth due to overcrowding in cities.

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.

Data gaps hobbling trial carbon markets Xu Nan Liu Shuang August 09, 2012 Seven Chinese regions are due to launch emissions-trading schemes next year. They will struggle to do so, write Liu Shuang and Xu Nan. Late last October, China's top economic planning body - the National Development and Reform Commission - instructed the cities of Beijing, Tianjin, Shanghai, Chongqing and Shenzhen, plus Hubei and Guangdong provinces, to get ready to run carbon-trading trials. These are not China's first experiments with emissions trading. In fact, the country has of late seen a proliferation of exchanges: according to Chinese newspaper 21st Century Business Herald, by the time of last year's announcement, many provinces and cities were already setting up their own carbon exchanges, or "energy and environment exchanges" - which in almost all cases include trading of emissions rights. But to date, the platforms up and running are either voluntary or tied into the UN clean development mechanism. Some places, including Chengdu, Ningxia and Xinjiang, are either considering similar exchanges, or planning to host branches of the Shanghai Environment and Energy Exchange, though these tend to mean nothing more than one employee in a single office. The seven Beijing-backed, mandatory trials kick-started last October represent a new level of ambition, however. Ten months on, how are they progressing? The short answer is: slowly. [...]

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."
