Britain hopes Biden will commit to net-zero target by 2050

British Prime Minister Boris Johnson said he hoped Joe Biden, who will be inaugurated as US President on Wednesday, would join Britain in its commitment to cut greenhouse gas emissions to net-zero by 2050.

"When it comes to global leadership on the world stage, this country is embarking on a quite phenomenal year," Johnson told parliament referring to Britain hosting the G7 and COP26 meetings.

He was responding to criticism by the former prime minister, Theresa May, who said some of Johnson's government's actions had lowered Britain's credibility in the eyes of the world.

"We hope that President Biden will join us (in setting a target to reach net-zero by 2050) and of course we will work with President Biden to secure the Transatlantic alliance and NATO," Johnson said.
