초록

On December 2003, Korean government legislated Special Act to improve deteriorating air pollution levels in the Seou lMetropolitan Area (SMA) and this Special Act has been in force until now. One of the main causes of air pollution was emissions from road transport in the SMA. For this reason, we analyzed NOx emission by three stages in order to analyze emission trend, policy impact and cause of emission variation from road transport. First, we estimated NOx emissions of road transport sources from 2001 to 2007 using Clean Air Support System(CAPSS) and analyzed emissions trend. Next, the virtual emissions from 2001 to 2007 were calculated by number of vehicles and compared with CAPSS emission. Finally, target allowable emission targeted at 2014 was analyzed to compare with CAPSS emissions. The summary of results are as follows. Total NOx emission from road transport during 2007 increased by 10 %, compare to 2001. The virtual total emission which was estimated by number of vehicles decreased by 42,528 tons due to application of various policies. Especially this significant gap indicated that emission reduction was a reflection of policy implementation of CNG buses supply. Finally, according to comparison between CAPSS emission and allowable emission, NOx emission at 2007 exceeded more than twice that of target allowable emission at 2014 and it is increasing trend every year. Therefore we need to implement various policies to reduce NOx emission in the SMA so as to attain target allowable emission at 2014.
