Biden could declare climate emergency - Kerry

The US climate envoy, John Kerry, says President Joe Biden is considering announcing a climate emergency.

The move would give him additional powers to push his renewable energy agenda, which has been held up by lack of support in Congress.

Mr Kerry told the BBC it was "less than ideal" that Congress was not "full-throatedly" in favour.

But he said nobody was more committed than President Biden to replacing carbon-based energy.
