1. Data source: Emission Database for Global Atmospheric Research (Edgar). Global emissions dataset: CO2 excluding short-cycle organic carbon from biomass burning (downloaded November 30 2015).
Note: These data are fossil fuel use and industrial process emissions (cement production, carbonate use of limestone and dolomite, non-energy use of fuels and other combustion). They do not include short-cycle biomass burning (such as agricultural waste burning) and excluding large-scale biomass burning (forest fires, etc.)

While the world was meeting in December in Paris to discuss what to do about climate change, Beijing issued its first air pollution red alert. For health reasons, people were advised to stay indoors, schools were closed and restrictions were imposed on the use of cars. Coal provides about two-thirds of China's energy, particularly in the north-east of the country, the area covered in the grey haze in this satellite image.
