This new assessment from the African Union Commission, the Climate and Clean Air Coalition, and the UN Environment Programme, developed by African scientists in a process led by SEI, shows how African leaders can act quickly across five key areas — transport, residential, energy, agriculture, and waste — to fight climate change, prevent air pollution, and protect human health. Air pollution and climate change are a deadly duo for Africa, and must be tackled together. Air pollutants and greenhouse gases often share the same sources and can be even more dangerous when combined.
