Abstract:
Based on carbon footprint, the output value and ecological pressure of carbon footprint, the use of energy from 2000 to 2007, the carbon footprint in regions in 2007 and the causes were studied, and some measures to optimize the use of energy were advanced. The results showed that the total and per capita of carbon footprint were rising, the per capita of carbon footprint increased from 10.45 hm2/per in 2000 to 28.61 hm2/per in 2007,the growth reached to 274%; the ecological pressure of carbon footprint were increased from 9.77 in 2000 to 26.74 in 2007, so as the per capita GDP. However, the output value of carbon footprint was decreased from 751.96 yuan/hm2 to 682.44 yuan/hm2; Carbon emissions in regions were different in 2007, the top was 2.98×1013t in Hebei province and the least was 2.25×1012t in Qinghai province. The differences of the output value and ecological pressure of carbon footprint among regions were distinct, and the both peak were in Shanghai.
