Abstract
Drawing
lessons from the clean development mechanism (CDM), this
paper developed a combined margin methodology to quantify baseline
emission factors of air pollutants in China’s regional power
grids. The simple average of baseline emission factors of SO<sub>2</sub>, NO<sub><i>X</i></sub>, and PM<sub>2.5</sub> in China’s
six power grids in 2010 were respectively 1.91 kg/MWh, 1.83 kg/MWh
and 0.32 kg/MWh. Several low-efficient mitigation technologies, such
as low nitrogen oxide burner (LNB), were suggested to be replaced
or used together with other technologies in order to virtually decrease
the grid’s emission factor. The synergies between GHG and air
pollution mitigation in China’s power sector was also notable.
It is estimated that in 2010, that every 1% CO<sub>2</sub> reduction
in China’s power generation sector resulted in the respective
coreduction of 1.1%, 0.5%, and 0.8% of SO<sub>2</sub>, NO<sub><i>X</i></sub>, and PM<sub>2.5</sub>. Wind is the best technology
to achieve the largest amount of coabatement in most parts of China.
This methodology is recommended to be used in making comprehensive
air pollution control strategies and in cobenefits analysis in future
