Analysis on Chongqing’s Carbon Balance Based on Carbon Footprints

Article Preview

Abstract:

Chongqing’s carbon balance based on carbon footprints is analyzed, which is defined CO2 emitted by human activities equal to CO2 absorbed by carbon sinks and carbon footprints elimination. On the basis of carbon balance calculation with indicators of measurement of CO2 emissions, conversion from CO2 to carbon footprint and rate of carbon neutral by CO2 sinks of forestation and greening, it is found that Chongqing’s carbon footprints grew from 5.0141 Mghas in 1997 to 10.2973 Mghas in 2009 with rate of about 6 per cent yearly, in which carbon footprints from fossil-fuels-combustion overwhelmingly increased from 50.3 per cent in 1997 to 79.48 per cent in 2009; and the gap exists in Chongqing’s carbon balance with being widen from 3.3271 Mghas in 1997 to 7.4133 Mghas in 2009, with enlargement rate of 1.809 per cent yearly.
