Recently, Science Advances, a science publication, published the research results of the research group of Professor Chen Bin of Beijing Normal University and the research group of the University of Maryland and Beijing University in the form of a research article. This study reveals for the first time the spillover effects and synergistic effects of regional air pollution control policies on atmospheric pollutants, climate change, and water consumption.
This study coupled the cross-regional input-output model and the atmospheric chemical transport model, based on the production-trade-emission-pollution-transport process. The effects of air pollution control policies on PM2.5 concentration, CO2 emission and water resource consumption in Beijing, Tianjin and Hebei were simulated. The results show that the PM2.5 emissions, secondary particulate matter emissions and PM2.5 concentrations in the Beijing-Tianjin-Hebei region have significantly decreased compared with the base year, indicating that a series of pollution prevention policies and measures have been introduced in China. The effect is remarkable.
Change Value of PM2.5 Emissions from China's Provinces and Cities in the Context of Beijing-Tianjin-Hebei Air Pollution Control Policy
Under the scenario of Beijing-Tianjin-Hebei air pollution control policy, the change value of PM2.5 emission from each province and city in China is due to industrial upgrading and trade transfer. Some pollutants spill over to the adjacent areas through economic activities and are transported back to Beijing-Tianjin-Hebei region through the process of atmospheric transmission, which weakens the ultimate effect of air pollution control policy to a certain extent. In addition, Beijing-Tianjin-Hebei region has significantly reduced CO2 emissions and water resources consumption while improving air quality, indicating that air pollution control, carbon emission reduction and water resources conservation can be achieved through the Nexus Management Model.
