Donald Trump has tweeted this morning that he will announce his decision on the Paris Agreement today.

It comes after the US President arrived home after a G7 summit in Brussels.

Mr Trump had refused to endorse the landmark accord at the weekend and left the G7 summit in Sicily with a parting-shot tweet saying he had not made up his mind on whether to back it.

World leaders, who had hoped to put out a statement of consensus on the Paris Agreement, expressed their frustration, with German Chancellor Angela Merkel declaring: "We have a situation where six, or if you also include the EU seven, are against one."


The decision will put the US in league with Syria and Nicaragua as the world's only non-participants in the Paris Climate Agreement - brokered by Mr Trump's predecessor Barack Obama in 2015.

I will be announcing my decision on Paris Accord, Thursday at 3:00 P.M. The White House Rose Garden. MAKE AMERICA GREAT AGAIN! — Donald J. Trump (@realDonaldTrump) June 1, 2017

Agreed on by up to 200 countries, the deal aims to reduce carbon dioxide and other emissions from the burning of fossil fuels.

The US is the world's second-biggest emitter of carbon dioxide behind China.

Under the deal, Mr Obama committed the US to cutting its emissions by between 26% and 28% from 2005 levels by 2025.

Mr Trump, who in a November 2012 tweet dismissed climate change as a hoax, pledged during his election campaign to "cancel" the accord within 100 days of becoming president to boost America's coal and oil industries.

US withdrawal could have major implications on the pact which relies heavily on the commitment of big polluter nations to reduce gas emissions which scientists blame for rising sea levels, droughts and frequent violent storms.

The move could also lead to other nations weakening or stepping back from their pledges under the pact.

China, India, Canada and the EU have said they will stick by the deal, even if the US pulls out.

The United Nations responded with a tweet quoting Secretary-General Antonio Guterres as saying: "Climate change is undeniable. Climate action is unstoppable. Climate solutions provide opportunities that are unmatchable."

Sky's US Correspondent Amanda Walker said: "His daughter Ivanka Trump has been trying to encourage him to stay in the deal.

"Whatever way he eventually goes will give a very clear indication as to where he is putting his own loyalty, where he is putting his weight.

"And that would suggest that at the moment he is going with his advisers, who are very much more isolationist, this 'America first' policy, which is something that Steve Bannon has really pushed, and his base felt really strongly about during the campaign.

"He is teasing this out, We've seen this before... he likes the theatre of this. This is a former reality TV star.

"But of course everybody on the climate change side of things is saying this is nothing to play with, build suspense about. This is a hugely important issue that is all about President Obama's legacy."

In March, the US President rolled back Mr Obama's record on climate change with a series of executive orders undermining America's commitment to tackling global warming.

They enabled regulators to rewrite key rules curbing US carbon emissions, lift a temporary ban on federal coal leasing and scrap a requirement for federal officials to consider the impact of climate change when making decisions.
