Carbon footprint of different industrial spaces based on energy consumption in China

Abstract

Using energy consumption and land use data of each region of China in 2007, this paper established carbon emission and carbon footprint model based on energy consumption, and estimated the carbon emission amount of fossil energy and rural biomass energy of different regions of China in 2007. Through matching the energy consumption items with industrial spaces, this paper divided industrial spaces into five types: agricultural space, living & industrial-commercial space, transportation industrial space, fishery and water conservancy space, and other industrial space. Then the author analyzed the carbon emission intensity and carbon footprint of each industrial space. Finally, advices of decreasing industrial carbon footprint and optimizing industrial space pattern were put forward. The main conclusions are as following: (1) Total amount of carbon emission from energy consumption of China in 2007 was about 1.65 GtC, in which the proportion of carbon emission from fossil energy was 89%.(2) Carbon emission intensity of industrial space of China in 2007 was 1.98 t/hm 2 , in which, carbon emission intensity of living & industrial-commercial space and of transportation industrial space was 55.16 t/hm 2 and 49.65 t/hm 2 respectively, they were high-carbon-emission industrial spaces among others. (3) Carbon footprint caused by industrial activities of China in 2007 was 522.34×10 6 hm 2 , which brought about ecological deficit of 28.69×10 6 hm 2 , which means that the productive lands were not sufficient to compensate for carbon footprint of industrial activities, and the compensating rate was 94.5%. As to the regional carbon footprint, several regions have ecological profit while others have not. In general, the present ecological deficit caused by industrial activities was small in 2007. (4) Per unit area carbon footprint of industrial space in China was about 0.63 hm 2 /hm 2 in 2007, in which that of living & industrial-commercial space was the highest (17.5 hm 2 /hm 2 ). The per unit area carbon footprint of different industrial spaces all presented a declining trend from east to west of China.

Changes in CO2 Emissions Induced by Agricultural Inputs in China over 1991–2014

“…Human-induced emissions of carbon dioxide or greenhouse gases, expressed in CO 2 equivalents and by the carbon footprint (CF), have attracted worldwide attention because of their important effects on the environment and global warming. In order to reduce CO 2 emissions caused by production and consumption and develop a low carbon economy, CF assessment has been gradually approved and used by many industrial enterprises and areas [5][6][7]. It is also commonly used to assess the impact of household and agricultural CO 2 emissions [8][9][10].…”

Effect of Construction Land Expansion on Energy-Related Carbon Emissions: Empirical Analysis of China and Its Provinces from 2001 to 2011

“…Thus, the energy consumption level determines the overall level of regional carbon emissions. If a corresponding relationship exists between carbon sources and land-use types, energy-related carbon emissions could also establish a corresponding relationship with construction land [7][8][9]. Studying the effect of construction land expansion on energy-related carbon emissions could provide a basis for efforts to reduce regional carbon emissions in relation to land-use regulation, and could expand the research scope of measures for reducing carbon emissions.…”

Allocating and mapping carbon footprint at the township scale by correlating industry sectors to land uses

“…Currently, the major CO 2 ‐emitting source is energy sectors (Intergovernmental Panel on Climate Change ; Huisingha and others ), of which 90.4 percent (around 5.404 billion tons) are in China (National Development and Reform Commission of China ). So far, however, there are few detailed data sources on energy consumption at provincial scales (Zhao and others ; Chuai and others ; Gao and others ).…”
