Abstract:
Air pollution in and near megacities are very severe because of their massive pollutant emissions and high population density. Korea has ambitiously set its 2nd phase capitol air quality improvement program called Seoul metropolitan area Air Quality Management Plan(SAQMP), targeting the year 2024. The air quality improvement targets for the year 2024 are 30 ug/m3 and 20 ug/m3 for PM10 and pm2.5, respectively and planned expenditure are almost 4 billion US dollar. Emissions of PM10, PM2.5 are required to be decreased up to 35%, 45%, respectively, from their future baseline level. Various special measures, such as cap-and-trade, LNB, EURO standards program, will be implemented to control emissions over Seoul, Incheon, and Gyeonggi-do area. Smart approach of reducing air pollution and GHGs are, however, required to maximize improvement of metropolitan air quality and climate change. IIASA’s Greenhouse gas – Air pollution Interactions aNd Synergies(GAINS) modeling framework is an widely used tool to design and manage smart emission control strategies that can achieve air quality/climate improvements with least costs. We have developed the national version of GAINS for Korea (GAINS-Korea) to set up those strategies for national and regional scale. In this study, we have implemented SAQMP in the GAINS-Korea Model and assess its effects of emissions reduction and air quality improvements. Various analysis results using the framework will be presented at site.
