Rich Countries Told to Close Coal Plants by 2030 to Save Climate

Rich countries must close all their coal-fired power plants by 2030 to have a chance of holding global warming to tolerable levels, a report from an environmental research group said. China would have to phase out the most polluting fossil fuel by 2040 and the rest of the world by 2050, according to Climate Analytics, a Berlin-based non-profit that is studying how nations can meet the emissions goals they agreed at United Nations talks in Paris last year.
