Air Quality Improvement Scenario for China during the 13th Five-Year Plan Period
China is suffering from severe air pollution especially fine PM2.5 pollution. In 2015, the annual average PM2.5 concentration of the 338 municipal cities was 50 μg/m3, 78% cities at or above the prefectural level failed to comply with the PM2.5 concentration standards. The 13th Five-Year Plan for Na...

| Summary: | China is suffering from severe air pollution especially fine PM2.5 pollution. In 2015, the annual average PM2.5 concentration of the 338 municipal cities was 50 μg/m3, 78% cities at or above the prefectural level failed to comply with the PM2.5 concentration standards. The 13th Five-Year Plan for National Economic and Social Development set the goal that the annual average concentration of PM2.5 in the municipal cities which failed to attain the ambient air quality standards shall be decreased by 18% by 2020 (CCCPC, 2016). In this study, an air pollution control scenario during the 13th Five-Year Plan period was proposed and the SO2, NOx and PM emission reductions in response to different measures in 31 provincial-level regions mainland China by 2020 were estimated. The air quality in the target year (2020) was simulated using the WRF-CMAQ model. The results showed that by 2020, the emissions of SO2, NOx and primary PM in mainland China will be reduced by 4.19 million tons, 3.94 million tons and 4.41 million tons, a drop of 23%, 21% and 25% respectively compared with that in 2015, and the annual average concentration of PM2.5 will decrease by 19%. Coal-fired power plant contributes the most pollutant emission reduction. |
