Carbon emissions fall as electricity producers move away from coal

Global emissions down by 2% amid mild winter and reduced use of coal-fired power plants

Carbon emissions from the global electricity system fell by 2% last year, the biggest drop in almost 30 years, as countries began to turn their backs on coal-fired power plants.

A new report on the world's electricity generation revealed the steepest cut in carbon emissions since 1990 as the US and the EU turned to cleaner energy sources.
