The world added the smallest amount of new coal capacity in two decades last year, a report said Thursday, but use of the fossil fuel is still surging in China and India.

Coal accounts for just over a third of global electricity production and phasing it out is fundamental to meeting climate change goals.

Just 44 gigawatts (GW) of new coal power capacity was produced globally last year, the lowest figure since 2004, according to the report by a group of energy-and environment-focused research organizations and NGOs.
