Short summary
The SO2 concentrations and NOx emissions over China derived from satellite observations are compared with the national fossil fuel consumption and air quality regulations. It is shown that not only NO2 concentrations but also NOx emissions in all Chinese provinces decreased in the last 2 years. We conclude that without the air quality regulations the SO2 concentrations would be about 2.5 times higher and the NO2 concentrations would be at least 25 % higher than they are today in China.
