Shandong Co < Sub > 2 < / Sub > Time And Space Differences Of Net Emissions And Low-carbon Path To Explore

Nearly two hundred years after the first industrial revolution, with the development of ourtechnology and the fast growing rate of urbanization and industrialization, our society haschanged enormously and our living standard has experienced a great improvement. But whatfollows is a serial of disasters such as global warming, sea-level rise and extreme weather whichcould lead us to a dangerous situation. We finally recognize that the main source of thesedisasters is the large emission of greenhouse gases, especially emission of CO₂. So we try tochange our development route into a low carbon emission one. But our researches on low carbondevelopment are not systematic. Net CO₂emissions are neglected when searching for low carbondevelopment routes. So routes obtained this way can not accommodate with the reality of thegiven region. What’s worse, researches on net CO₂emissions belong to natural science andsocial science respectively, and communications are quite few, which is not a good news toresearches on low carbon development. Moreover, most of recent studies are focus on nationalscale. But studies on provincial scale are scarce.This paper is supported by the innovation foundation of Shandong normal university. In thispaper, I choose Shandong province as the research region. Shandong province located in the eastcoast has the familiar spatial differences with China. So study on Shandong province is typicalityand can set an example.This paper constructs a net CO₂emission measurement system and chooses a serial ofcomputing methods. Then, the quantity of CO₂emission in Shandong province and its 17 cities iscalculated. Then the spatial-temporal differences and their reasons are analyzed. Finally, lowcarbon development routes are given based on above analysis. Conclusions are listed as follow:（1） The quantity of net CO₂emission in Shandong province is rising year by year. But after2006, the rising tendency becomes slow, and approaches the peak of inverted U curve. Thetendency of CO₂emission is smooth. But the trend of CO₂absorption is not so steady. It rises andfalls around the line of 160million ton.（2） Emissions in every department of Shandong province have increased. Secondaryindustry and thermal power generation are the greatest source of CO₂emission in Shandong, then are heat addition and Tertiary industry, the last is living consumption and primary industry.Energy consumption in industrial produce process contributes a lot to CO₂emission in secondaryindustry. Transportation, Storage and Post contributes a lot to CO₂emission in tertiary industry.Emissions of primary industry and living consumption account for very small proportions. After2006, emission of secondary industry grows very slow. But emission of tertiary industryincreases fast. The emission intensity of secondary industry is larger than those of primary andtertiary industries.（3） Spatial differences of net CO₂emission in Shandong are very large. High net CO₂emission regions are located in Jinan, Zibo, Qingdao. Spatial differences of CO₂emission inShandong are large and are narrowing year by year. Its emission barycenter moves from thenortheast to the southwest.（4） The net CO₂emission in Shandong province has two rising core. High increasing citiesof net CO₂emission are Zibo, Weifang, Qingdao, Rizhao and Jining. High increasing cities ofCO₂emission are Yantai, Qingdao, Rizhao, Weifang, Jinan and Zibo. While high increasingcities of CO₂absorption are Yantai, Dezhou, Liaocheng, Heze, and so on.（5）The main energy consumed in Shandong is coal. The proportion of high energyconsuming industries is quite large. Energy consumption per 10 thousand in secondary industryis higher than Zhejiang, Tianjin, Jiangsu, Jiangxi, Guangdong, Beijing, Shanghai and Fujian.Energy consumption per 10 thousand in tertiary industry is quite high. It is even higher than themiddle district.（6）In the past 10 years, CO₂emission in Shandong province is greatly influenced by energyconsumption per person, energy intensity in economic department and economic intensity.Influences of industrial structure, energy consumption structure and population scale are verysmall. CO₂emission differences in 17 cities are main caused by nature condition, economy scale,industry structure and urbanization.（7）There are opportunities and challenges in low carbon development in Shandong. Lowcarbon development routes are as follow: government should exert leading role and promote thelow carbon transformation of institution; relying on scientific research institutions, develop lowcarbon technologies; encourage the exploration of new energy resources, change energyconsumption structure, et al.
