Abstract

Vietnam will achieve net-zero greenhouse gases(GHG) emissions by 2050. Ho Chi Minh City (HCMC) has aconsiderable amount of GHG emissions (accounted for 20,68%of total GHG in Vietnam). The main GHG sources in HCMCare mainly due to the numerous private vehicles used and theincreasing rate of factories. Therefore, to reduce the GHG ofthe city from these two sources, the bottom-up GHG detailedemission inventory (EI) for major sources must be carried outto determine the potential GHG emission sources. Theobjectives of this research are 1) to develop detailed GHG EI forHCMC and 2) to develop measures to reduce GHG for HCMC.It is the first bottom-up GHG emission inventory study thatapplied the EMISENS model to calculate the GHG emissionfrom traffic and industrial sources. The total GHG emission ofHCMC in 2019 was 58,272,149 tons CO2eq/year. The primaryemission of GHG in HCMC is from on-road traffic (13,484,958tons CO2eq/year) and the industry sector (17,612,942 tonsCO2eq/year). Motorcycles contribute the highest (63%) GHGemission from on-road transportation, whereas the chemicalindustry contributes the highest (63%) GHG emission fromindustry sources, followed by the sectors of Paper Production(17.3%), Textile (16.1%), and Metal production (14.7%). Thestudy also developed technical and management solutions toachieve the goal of GHG emission reduction for HCMC andcontribute to the National target of net-zero GHG. The mainmanagement solutions are based on implementing a CarbonReporting System for industries and buildings in the city.
