Abstract

The purpose of this study is to evaluate the diesel retrofit program which have been proceeded for the last 7 years in Gyeonggi-do. Diesel retrofit programs in Gyeonggi-do consist of the attachment of DPF (Diesel Particulate Filter), p-DPF (partial-DPF) and DOC (Diesel Oxidation Catalyst), switching to LPG engine, scraping an old cars. Emission reduction by diesel retrofit program was estimated $N_2O$ 8,313.4 ton/year, PM10 3,626.4 ton/year, VOC 8,078.5 ton/year in 2010. The benefit-cost analysis shows that the 964 billion wons of benefits are greater than the 853 billion wons of total costs. Diesel retrofit programs could be one of the most effective measures to improve PM10 concentration in metropolitan area. But retrofit programs also need to be properly maintained by each vehicle.
