Emissions Comparison of Short Lived Climate Forcers Over Long Term Greenhouse Gases From Domestic and Transport Sector in Semarang City

Abstract

Short-lived climate forcers (SLCF) controls are important because of their shorter impact and more immediate benefits in the short term than carbon dioxide controls that have a 100-year time horizon. In this study, we estimated the emission of SLCF from domestic and transport sector in Semarang city using emission factor from IPCC and CORINAIR. We also predicted the emission dispersion using AEMOD View. The total consumption of LPG domestic sector in Semarang City is 48,532 tons in 2017 and produces total SCLF emissions 0.537 tons/year and 11,538 tons/year for BC and CH4 respectively. This corresponds to CO2 emissions of 145,611 tons/year and 230.76 tons/year of N2O emissions. While from transport sector, the motorcycle has the largest VKT i.e 18.282.061.600 km/year in 2017. The emission, based on VKT data combined with active vehicles data, reach 178.23 tons/year, 802.52 tons/year for BC and CH4 respectively. Transport sector produces total CO2 emissions almost 15 times to that of domestic sector. Based on emission model, the emission distribution was concentrated in the districts located in the city center. The pollutant was accumulated in the Northwest, city center and Southeast of the city.
