Theresa May urges world leaders to tackle climate crisis - but US refuses

Theresa May has called on other countries to "raise their ambition" and copy the UK by aiming for net zero carbon emissions by 2050.

The prime minister said she wanted other world leaders to "embrace this target" as she held a news conference at her last G20 summit.

It came as Donald Trump confirmed he would not be changing his mind on climate change action, saying US factories don't work on wind power and he doesn't want to subsidise green energy.

His stance means the US is the only country in the G20 that has not reaffirmed its commitment to the full implementation of the 2015 Paris climate accord.

Mrs May told reporters: "Over the past two days, leaders have discussed some of the most pressing challenges facing our nations.

"In recent months we have heard hundreds of thousands of young people urge us - their leaders - to act on climate change before it's too late.

"I am proud that the UK has now enshrined in law our world-leading net zero commitment to reduce emissions. And I have called on other countries to raise their ambition and embrace this target."
