『Abstract
This study has proposed a new solution concerning fuel consumption
in China's transport sector, which has provided a more accurate
basis for estimating CO2 emissions in the
transport sector on national and regional level. Our analysis
indicated that CO2 emissions in China's transport
sector in 2007 reached to 436 Mt, higher than 408 Mt estimated
by IEA. The CO2 emissions in transport sector
accounted for 7% of China's total fossil fuel combustion CO2 emissions, which is much lower than the global
average level of 23%. The CO2 emission from
road transportation was 376.6 Mt, 37% higher than IEA's estimation.
Therefore we thought IEA significantly underestimated the amount
of CO2 emissions from road transportation
in China, inevitably they overestimated CO2
emissions in other transportation means. The IEA's result of road
transportation CO2 emissions is only 67.64%
in the entire transport sector, but our study showed this ratio
could be up to 86.32%. This study also preliminarily analyzed
the driving-forces of CO2 emissions in transport
sector at regional level. The results showed that the CO2 emissions in transport sector are closely associated
with GDP. Finally the article had reviewed some policies in China's
transport sector.
