Luciano Cessari, Elena Gigliarelli In: Progress in Cultural Heritage Preservation Lecture Notes in Computer Science Volume 7616, 2012, pp 369-377 Abstract Climate change have impacts on many sectors: land use, housing, transportation, public health, water supply and sanitation, solid waste, food security, and energy. This article presents the results of the project SECHURBA, financed by European funds, whose purpose was to examine the potential of environmental protection and sustainability in historic cities, documenting barriers and prospects of various historical communities with diversity in Europe. Critical objectives which were achieved, such as 'Historic Community Climate Change Strategies', assessment tools, route maps to intervene in areas such culturally sensitive, are under implementation in historic urban areas in Popular Republic of China. Through the application to some typical towns and villages in the Chinese province of Zeijang the outcomes of SECHURBA will developed to outline a set of actions and tools that will call 'Historic Cities Regeneration by Climate Change Strategies'.

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.

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.

The aim of this paper is to understand the sustainability of urban spatial transformation in the process of rapid urbanization, and calls for future research on the demographic and economic dimensions of climate change. Shanghai towards its transformation to a metropolis has experienced vast socioeconomic and ecological change and calls for future research on the impacts of demographic and economic dimensions on climate change. We look at the major questions (1) to explore economic and demographic growth, land use and land-cover changes in the context of rapid economic and city growth, and (2) to analyze how the demography and economic growth have been associated with the local air temperature and vegetation.

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: 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.

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."

[ScienceDirect, via Biblio-SHS] Auteur : Shuxiao Wang, Jiming Hao Paru dans : Journal of Environmental Sciences, Volume 24, Issue 1, January 2012, Pages 2-13 Abstract This article analyzed the control progress and current status of air quality, identified the major air pollution issues and challenges in future, proposed the long-term air pollution control targets, and suggested the options for better air quality in China. With the continuing growth of economy in the next 10-15 years, China will face a more severe situation of energy consumption, electricity generation and vehicle population leading to increase in multiple pollutant emissions. Controlling regional air pollution especially fine particles and ozone, as well as lowering carbon emissions from fossil fuel consumption will be a big challenge for the country. To protect public health and the eco-system, the ambient air quality in all Chinese cities shall attain the national ambient air quality standards (NAAQS) and ambient air quality guideline values set by the World Health Organization (WHO). To achieve the air quality targets, the emissions of SO2, NOx, PM10, and volatile organic compounds (VOC) should decrease by 60%, 40%, 50%, and 40%, respectively, on the basis of that in 2005. A comprehensive control policy focusing on multiple pollutants and emission sources at both the local and regional levels was proposed to mitigate the regional air pollution issue in China. The options include development of clean energy resources, promotion of clean and efficient coal use, enhancement of vehicle pollution control, implementation of synchronous control of multiple pollutants including SO2, NOx, VOC, and PM emissions, joint prevention and control of regional air pollution, and application of climate friendly air pollution control measures.

Introduction Globalization has brought China ever close to the rest of the world not only through its trade and transport networks, but also many transport-related issues that seem to be in common among other countries, while simultaneously with special causes deep-rooted from its unique pathway of development especially in the past several decades. The major fundamental difference of China's development from other countries lies in its economy in general, while the transport sector, in particular, lies in the role of the government. Indeed, since the global financial crisis in 2008, advanced economies, such as the US and several EU countries, have intensified on how to redefine and strengthen the role of the state within respective economies. On the contrary, the Chinese situation is exactly the other way round: the debate is about how to reduce interferences from the very strong hands of the government towards a real regulated market. In this respect, the transport sector typifies this ongoing marketization process. On one extreme, the mode of highway transportation is fully marketized: private investors may construct toll expressways in almost any provinces, either as joint ventures partnering with state-owned firms or just as fully private developers. On the other side of the continuum, after more than three decades of 'reforms', railway infrastructures, as well as their operation, are still fully and tightly controlled by the Ministry of Railways (MOR) through its subsidiary's monopoly. In-between the highways and railways are air and maritime transportation, both of which being characterized by oligopolies with two to three state-owned listed companies taking up more than 80% of the market share. Given such situation, there is a clear interest for further understanding and re

The simulation of land use change is important in environmental impact assessment and land use planning. We assessed the land use scenarios of China in the next 100 years based on the SMLC (surface modelling of land cover change) model and Dyna-CLUE (dynamic conversion of land use and its effects) model. Three SRES scenarios were evaluated: Global Economy (A1FI): lean government, strong globalization; Continental Markets (A2a): lean government, regional culture and economic development; Regional communities (B2a): much government intervention, regional cultural and economic development. Ten land cover types were simulated, which are cultivated land, woodland, grassland, built-up land, water area, wetland, nival area, desert, bare rock and desertification land. The SMLC model was used to calculate changes in area for each land use types in the future at country level while the spatially explicit land use model Dyna-CLUE was used to simulate land use pattern at 2 km2 resolution based on the country level areas demands for each land cover type. The results show that the cultivated land would decrease in all of the three scenarios, while in the A2a scenario, the cultivated land would decrease with the lowest rate because of the high population growth, high level of market protection and low agricultural efficiency; in the B2a scenario, it would decrease with the highest rate caused by the decreased population numbers and increased crop productivity. The nival area would decrease with the highest rate in the A1FI
