| Abstract: | Large amounts of methane (CH4) and nitrous oxide (N2O) are released during the operation of sewage treatment plants, which are important sources of man-made greenhouse gas emissions. Based on 2005-2015 statistical data and IPCC accounting methods, the CH4 and N2O emissions from domestic sewage treatment plants in China from 2005 to 2015 were estimated, characteristics and influencing factors were analyzed. Three emission reduction scenarios (low emission reduction, medium emission reduction and high emission reduction) were set based on the carbon neutral background, and emission trends and temporal and spatial changes from 2020 to 2050 were estimated. The results showed that the greenhouse gas emissions of sewage treatment plants increased steadily from 2005 to 2015. CH4 increased from 11.35 Mt CO2e to 15.01 Mt CO2e, and N2O increased from 26.51 Mt CO2e to 27.87 Mt CO2e, the average annual growth rate was 2.8% and 0.5%, respectively. Under the three emission reduction scenarios, CH4 and N2O emissions from 2020 to 2050 show a trend of increase first and then decrease, and CH4 and N2O emissions under the low emission reduction scenario will peak in 2036 and 2025, respectively, with 24.31 Mt CO2e and 28.19 Mt CO2e; CH4 peaks in the medium and high emission reduction scenarios will occur in 2027 and 2025, respectively, while the peak N2O emissions will both occur in 2025. Compared with the low emission reduction scenario, the respective emission reduction rates of CH4 emissions under the medium and high emission reduction scenarios are about 47% and 94% in 2050. N2O emissions under the low, medium and high emission reduction scenarios in 2050 will be reduced by 12%, 53% and 95% respectively compared with 2015. There are significantly spatial differences in the emissions of CH4 and N2O. East China has the highest emissions and Northwest China has the lowest ones. The overall emission pattern is that the provinces in the southeast are higher than those in the northwest. Among the influencing factors, the level of economic development is closely related to greenhouse gas emissions. |
