Coal causes climate change: Coal burning is responsible for one-third of all our carbon dioxide pollution (CO2). It is the most polluting way to generate electricity accounting for over 70 percent of the CO2 emissions from the power sector. CO2 is the most prevalent of the greenhouse gasses (GHGs) fuelling the greatest environmental, humanitarian and economic threat, the world has ever faced. According to the mining experts study the potential cost of dealing with the climate change caused by this CO2 will be up to 20 percent of the world’s GDP by 2100. Avoiding climate changes worst impacts means halting the growth in CO2 emissions by 2015 and then reducing the emissions radically thereafter.
