Human activity in Africa significantly contributes to air pollution. However, no detailed data regarding country-by-country pollutant emissions in the continent was available until now. To remedy this scientists mapped these emissions in Africa for 2005, before estimating them for 2030, using three scenarios. The researchers showed that the climate change models used by the IPCC underestimate Africa’s emissions, which could account for 20-55% of global anthropogenic emissions of gaseous and particulate pollutants by 2030.
