The Environmental Impacts of Coal

2021-2-19  The environmental effects of coal use range from the poisoning of local rivers by acid mine drainage to the global problem of climate change caused by CO2 (carbon dioxide) emissions. ‘Clean coal’ technologies are expensive and are still unable to completely remove harmful emissions from coal-fired power plants.ii Figure 1 illustrates the various impacts of coal-use on land water and air.
