Establishing a climate-friendly framework and co-control strategies in China’s atmospheric pollution prevention and control law will reduce both greenhouse gas emissions and conventional air pollutants together. China has been exerting great effort in addressing climate change and air pollution, and it would make sense to build upon its achievements by establishing a systematic and in-depth co-control pollution reduction policy framework. Building on the recommendations in our July 2009 report, this report focuses in greater depth on the most recent climate policies and state and regional programs.
