Emission inventory of rural civilian sources surveyed in households and the emission reduction effects of clean energy policies
Based on the energy consumption model established by the national rural domestic fuel consumption survey data,this study simulated the coal and biomass consumption level at the county level in 2015,and constructed the greenhouse gas and air pollutant emission inventory of rural domestic energy.On this basis,2025 is taken as the policy effect year to evaluate the emission reduction effect of the clean transformation of rural living energy.The results show that the consumption of coal and biomass fuel by rural residents in 2015 was 169.5Mt and 242.0Mt,respectively.The resulting emissions of PM25,VOCs,SO2,NOx,CO and CO2 were 2.91 Mt,1.98Mt,2.39Mt,524.3kt,43.0Mt and 642.9Mt respectively,among which Hebei Province was the highest emission province.By 2025,the total emissions of greenhouse gases and air pollutants in the no-policy scenario will be reduced by about 15%compared with 2015,and in the northern heating region,where the role of clean transition policies is most obvious,compared with the no-policy scenario,The emissions of PM2.5,VOCs,SO2,NOx,CO and CO2 were reduced by 76.0%、76.7%、75.6%、55.4%、76.6%and 43.2%,respectively,which has an ideal pollution reduction effect.
