Abstract—Vietnam will achieve net-zero greenhouse gases (GHG) emissions by 2050. Ho Chi Minh City (HCMC) has a considerable amount of GHG emissions (accounted for 20,68% of total GHG in Vietnam). The main GHG sources in HCMC are mainly due to the numerous private vehicles used and the increasing rate of factories. Therefore, to reduce the GHG of the city from these two sources, the bottom-up GHG detailed emission inventory (EI) for major sources must be carried out to determine the potential GHG emission sources. The objectives of this research are 1) to develop detailed GHG EI for HCMC and 2) to develop measures to reduce GHG for HCMC. It is the first bottom-up GHG emission inventory study that applied the EMISENS model to calculate the GHG emission from traffic and industrial sources. The total GHG emission of HCMC in 2019 was 58,272,149 tons CO2eq/year. The primary emission of GHG in HCMC is from on-road traffic (13,484,958 tons CO2eq/year) and the industry sector (17,612,942 tons CO2eq/year). Motorcycles contribute the highest (63%) GHG emission from on-road transportation, whereas the chemical industry contributes the highest (63%) GHG emission from industry sources, followed by the sectors of Paper Production (17.3%), Textile (16.1%), and Metal production (14.7%). The study also developed technical and management solutions to achieve the goal of GHG emission reduction for HCMC and contribute to the National target of net-zero GHG. The main management solutions are based on implementing a Carbon Reporting System for industries and buildings in the city.
