- Abstract:
- In this paper, carbon emissions in Shaanxi Province during the period of 1980—2011 were calculated according to the approach of IPCC for carbon emission. Changes in total carbon emission, carbon emission structure as well as the carbon emission in different industries and different industrial sectors were systematically analyzed. The decoupling model was applied to discuss the decoupling relationship between economic growth and energy carbon emission in Shaanxi Province. The results show that the total carbon emission and carbon emissions caused by coal use were increasing as N-shape curve during the 1980—2011, carbon emission caused by oil and natural gas use were increasing in Shaanxi Province from 1980 to 2011. Carbon emissions came mainly from coal consumption; industrial sector is the main carbon emissions sector. Among all the industrial sectors, the heavy industry and electricity, gas and water production industry were the larger contributors of carbon emissions, which make up 48% and 37% of the industry carbon emissions, mining industry was the next closest sector at 11%, the lowest sector was light industry of 4%. By comparing carbon emissions from different industrial sectors, carbon emissions come mostly from electricity and heat production industry, chemical raw material and chemical products manufacturing industry, petroleum processing, coking plant and nuclear fuel industry, petroleum and natural gas exploitation industry, nonmetal mineral product industry, black metal smelting and rolling processing industry, coal mining and washing industry and nonferrous metal smelting and rolling processing industry. In 2005 and 2010, these 8 industrial sectors generated 92.56% and 95.11% of industrial carbon emissions; Shaanxi Province pertains to weak decoupling at a national level during the period of 1980—2011, except for the period of 1981 and 1997—2000 which were strong decoupling and 1981 and 1997—2000 which were expansive negative decoupling. Increasing energy efficiency was the main reason for weak decoupling, but it failed to offset the economic development for growth of energy demand, and the development trend of weak decoupling will continue for some times in the future.
