The UK’s progress in reducing greenhouse gas emissions slowed last year, Ofgem has said.
Greenhouse gases fell by 2.5% last year, down from 3% the previous year and the smallest reduction since 2012, according to the regulator’s annual state of the market report.
It warned that “significant” investment and policy intervention, particularly in renewables, would be needed to meet the UK’s legal goals of reaching net zero emissions by 2050.
Greenhouse gas emissions have fallen by 42% since 1990, more than any other large advanced economy, due largely to the decarbonisation of electricity generation, Ofgem said.
Transport continued to be the largest single source of carbon emissions, although these fell slightly last year (3%), partly down to an increase in the number of alternative fuel vehicles which now account for 2% of the licensed cars on the road.
Ofgem has made decarbonising the economy a priority in its new corporate strategy and has promised to set out more detail on this early next year.
Joe Perkins, chief economist at Ofgem, said: “Ofgem’s latest state of the market report shows the progress made so far to decarbonise the economy but much more needs to be done.
“We want the UK to remain a global leader in bringing down greenhouse gas emissions, and our major objective is to help the country rise to the challenge of cutting emissions to net zero by 2050 at the lowest possible price to consumers.
“As well as protecting consumers in the future, our duty is also to protect those today.
“We will continue to enable competition and innovation which benefits consumers, whilst protecting those who need it, as we help build an energy market which works for all consumers.”
