The Research Of China’s Embodied CO₂ Emission Intensity Based On The Energy Consumption

Global warming has been the irrefutable fact. Excessive CO2 emissions threaten people’s life seriously. To solve the greenhouse effect problems, Chinese government has taken active measures, enacting a series of energy conservation and emission reduction policies, to restraint greenhouse gas emissions. The aim of this paper is to discuss the availability of these policies.Firstly, this paper examines the relationship between economic growth, energy consumption and CO2 emissions by using decoupling model. The result shows that the relationship between them is in a weak decoupling state. It suggests that along with economic development, China have taken effective measures to cope with the problem of high energy consuming. Secondly, based on input-output method and national economy statistical data from 2007 to 2012, this paper calculates 32 sectors’s embodied CO2 emission intensity and verifies the effects of energy-saving emission reduction policies. The empirical results show that:(1) although total CO2 emissions in each sector has been rising year by year, the embodied CO2 emission intensity is declining; (2) key sectors’embodied CO2 emission intensity show more obvious decline; (3) implementating energy-saving emission reduction policies on the second industry has an important effect on reducing the overall embodied CO2 emissions intensity; (4) the price of energy has an important effect on the embodied CO2 emission intensity. Finally, this paper puts forward the following suggestions:(1) adjust and optimize the industrial structure; (2) strengthen the management of energy conservation and emission reduction on the second industry; (3) optimize the energy products structure; (4) adjust energy products comparison relations reasonably.
