What percentage of China's Electricity is produced by coal?
Coal still takes the lion's share, producing more than 60 percent of both electricity and total energy. Last year, coal burning in China set another record, increasing 4.6 percent as the economy roared back after the COVID lockdowns of 2020.
Will China's coal use peak by 2025?
President Xi Jinping announced last year that China's coal use would peak by 2025. But so far there is no national roadmap for how to phase it out—even though ending coal burning is essential for meeting the country's commitment under the Paris Agreement to peak its total carbon emissions by 2030 and to become carbon neutral by 2060.
Should China phase out coal by 2050?
In its latest assessment report, released earlier this month, the Intergovernmental Panel on Climate Change (IPCC) said the world must phase out coal completely by 2050 in order to limit warming to 1.5 degrees Celsius (2.7 degrees Fahrenheit). Thus a lot is riding, for China and the world, on the success of the pilot project now underway in Shanxi.
