The UK's plan for a “Green Industrial Revolution” was praised for its ambition on hydrogen and electric vehicles, as the nation's high-level policy spree ahead of COP26 also faced questions over the roles of nuclear and carbon capture.

Prime Minister Boris Johnson’s long-trailed ’10 point plan’ for the green economy promised to mobilise £12bn ($16bn) of government investment, and up to £36bn from private sources, behind marquee pledges such as ending the sale of new petrol and diesel cars by 2030 – a decade earlier than previously planned – along with parallel moves to support electric vehicles.
