U.K. Prime Minister Boris Johnson announced a £12 billion ($15.9 billion) plan to boost green industries and tackle climate change in a blueprint he says will create or support as many as 250,000 jobs.

As he seeks to relaunch his premiership and revive the economy, Johnson aims to use his plan for a "green industrial revolution” to deliver on his pledge to invest in former industrial heartlands that voted for him at last year’s election.

Under the wide-ranging proposals, sales of new petrol and diesel cars will be banned from 2030, the government will back investment in electric vehicles, hydrogen, wind and nuclear power, and measures to make homes more energy efficient.
