Short summary
Vehicle emissions are a major source of Beijing's pollution. Various vehicle emission control policies have been implemented at great cost, but there is a lack of appropriate methods to evaluate the effectiveness of such policies. Here we developed a new method to evaluate the effectiveness of vehicle emission control policies during APEC. Our findings are instructive for air pollution control policy making.
