In the field of wastewater treatment, a quality-assured carbon database system will serve as a basis for determining greenhouse gas emission quotas and aiming to prepare Vietnam's carbon market in the period from now to 2025. This article presents the results of calculations to determine the volume of greenhouse gas emissions (including emissions of methane CH4 and nitrous oxide N2O) from concentrated domestic wastewater treatment plants in urbans of the region North. The inventory calculation period is determined from the official operation of the plant to 2024. Total CH4 and N2O emissions during the calculation period of 29 plants correspond to normal emission scenarios (BAU) is 378.0 and 79.7 x 106 tons CO2e, low emission scenario is 363.8 and 6.4 x 106 tons CO2e, high emission scenario is 476.1 and 13,103.9 x 106 tons CO2e. On this basis, state management agencies as well as local authorities can propose the most appropriate and effective strategic directions for green growth urban development.
