Abstract

Retrofitting older equipment with the catalyzed diesel particle filter (CDPF) or Diesel Oxidation Catalyst (DOC) can reduce PM emissions from older equipment. Few studies have compared different retrofit technologies for cost-effectiveness. According to the database of the Hong Kong Environmental Protection Department (EPD), this study analyzes the cost-effectiveness of CDPF and DOC technologies in promoting PM emission reduction from construction equipment. The results show that the annual total PM emissions from the six types of construction equipment are 167,783.07 kg. CDPF technology is lower than DOC technology in terms of emission reduction and the unit cost of emission reduction, but the cost is also higher. It is suggested that the government should promote different retrofitting technologies to reduce PM emissions from older construction equipment in Hong Kong according to its own emission reduction targets and financial budgets. governments with different fiscal budgets can use these results as a reference.
