Britain will move up a ban on new petrol and diesel cars and vans to 2030 and is eyeing 250 000 new jobs as part of a green industrial revolution, Prime Minister Boris Johnson said as he tries to meet Britain’s net zero emissions climate target. Johnson is seeking to show his government is on track to deliver manifesto promises after a tumultuous few days in which he was forced to self-isolate after coming into contact with someone with Covid-19, and his most senior adviser, arch Brexiteer Dominic Cummings, was ousted.
