Wen, Z., Ma, X., Xu, W. et al. Combined short-term and long-term emission controls improve air quality sustainably in China. Nat Commun

Objective:

• Gain new insight into the response of air quality to Nr emission changes driven by short-term compared to long-term policies and to understand how PM2.5 and N composition are changing under the influence of anthropogenic activities and climate change

Case:

• China, grid

Methodology:

• Random Forest
• ANOVA

Data Source

• SO2
• NO2

Findings:

• Short-term abatement measures during important international events substantially reduced PM2.5 concentrations, but air quality rebounded to pre-event levels after the measures ceased

• Long-term adherence to strict emission reduction policies led to successful decreases of 54% in PM2.5 concentrations in Beijing
