Analysis of the Relationship between China’s IPPU CO2 Emissions and the Industrial Economic Growth

According to the 2006 IPCC Guidelines for National Greenhouse Gas Inventories (IPCC 2006) and based on the production technology and products, this paper has calculated CO2 emissions from industrial processes and product use (IPPU), which involves the individual and the summation of five major IPUU CO2 emissions industrial departments. As there is a classic environmental Kuznets curve between IPPU CO2 emissions and the economy, this paper discusses the relationship based on the calculation results and the actual situation. The results show that the overall emission level is indeed rising yearly, and that steel and iron alloy manufacturing and nonmetal manufacturing occupy about 80% of the total emissions. The IPPU CO2 emissions and the corresponding gross industrial output value do not present a classic Kuznets curve in most industrial sectors due to the increasing industrial employed population. The year 2002 appears to be the boundary instead, where prior to 2002, there is a relatively stable function-type growth curve and after 2002, gross industrial output value (GIOV) per employed person remained within a certain interval while IPPU CO2 emissions per employed dipped slightly then increased again. Some, but not all, industrial departments and the combined emissions of per employed person reached maximum values in 2012.
