Harmful emissions from energy supply fell sharply last year, official statistics have revealed.
Provisional figures released by the government showed that 136M tonnes of CO2e were attributed to the sector in 2015.
This was down 19.6Mt from 2014 – almost double the 10.3Mt average reduction seen over the previous four years.
The Department of Energy and Climate Change said the fall in emissions was driven by a change in the fuel mix. It said there was less coal used in energy generation last year, and more nuclear power and renewables.
Overall greenhouse gas emissions were down 3% in 2015 to 497.2Mte. This represented a fall of more than a third from 1990.
The UK is committed by the Climate Change Act to reduce emissions by 80% from 1990 to 2050.
CO2e is a measure of greenhouse gas emissions that includes carbon and other substances adjusted to represent equal harm.
Academics recently insisted connections to carbon storage sites should be one of the factors taken into account when new gas power plants were planned.
