Status of CO_2 emissions,driving forces and mitigation countermeasures of Tianjin,China

Climate change is a long-term and important challenge facing the whole world. Mitigation of CO2 emissions is one ofimportant measures responding to climate change. The task of responding to climate change facing each city is very urgent. The total amount of Tianjin City's CO2 emissions from energy use and industrial processes is large and the amount of CO2 emissions per capita from fossil fuel combustion is quite high. Mitigation of CO2 emission in Tianjin City encounters many difficulties such as increasing population, rapidly growing economy, heavy industrial structure, backward tertiary industry, low level of energy efficiency and product technologies, and energy structure relying mainly on coal. This paper analyzes Tianjin City's general situation of economic and social developments, estimates Tianjin City's status of CO2 emissions using 2006 IPCC Guidelines for National Greenhouse Gas Inventories, analyzes Tianjin City's driving forces of CO2 emissions by methodology to analyze the driving forces of energy-related CO2 emissions, and puts forward countermeasures mitigating CO2 emissions in Tianjin City, such as strictly controlling increasing population, expediting industrial structure adjustment, insisting on strategy of energy conserving, vigorously enhancing energy efficiency, exploiting and using clean and renewable energy, advancing energy structure adjustments, and actively developing carbon capture and storage (CCS) technologies.

Investment risk analysis of China's wind power industry based on pre-assessment matrix

Wind energy is a clean and sustainable energy,and wind power does not rely on fossil fuels.So there is no fuel price risk,and it,of course,does not include the environmental costs,such as carbon emissions.Because of these unique advantages,wind power has gradually become an important part of the strategy of sustainable development in China.Now with the growing voices on global greenhouse gas emission reduction,and as a clean and efficient energy, wind power has huge potential in combating climate change,energy security pressures and the needs for energy.Wind power in China began to develop from the 1980s.In the first 20 years,the speed of development was slow;but since 2004,it has had an extremely rapid growth.This paper,in order to study the development mechanism of China's wind power industry,investigated and analyzed the status quo of wind power industry in China,and then found that(1) the development trend of wind power industry in China appears exponential growth;(2)China's installed capacity of wind power is still smaller than that os some other countries;(3)new subsidy policies bring developing opportunities to wind power industry in China;(4)the sectors of wind power industry are in unbalanced growing;(5)the owners of proposed wind farms are too optimistic though the built wind farm had many problems.In addition,by using the methodology of Game Theory,this paper has also constructed the matrix of pre-assessing risks of China's wind power industry to further discuss the potential risk factors within China's wind power industry as risk factors of wind farm construction,risk factors of production of wind turbines,risk factors of parts and components manufacturing industry under risk indicators like R&D,patents,the domestic policy,the international policy,the quality of products and the market regulation,in order to provide a scientific assessment and self-assessment tool for investors or implementers, and also to promote the further development of the wind power industry.
