The official insisted on anonymity in order to discuss the decision before the official announcement.
A month ago, Gov. John Hickenlooper was one of 12 Democratic governors who formally asked Trump not to pull out of the agreement. Withdrawing would leave the United States as one of just three countries outside the agreement. Climate change is unstoppable. "Climate solutions provide opportunities that unmatchable". "On top of that, the rest of the world will move forward without us in terms of innovation and worldwide diplomacy while the USA will be stuck in the polluting days of the past". If Trump does pull out of the pact, it would make the US one of only three countries to not be included in the historic agreement.
Notably, two major coal producers, Cloud Peak Energy (CLD) and Peabody Energy (BTU) , had advised the Trump administration to remain in the pact, to prevent concerted worldwide action against coal companies.
Johnson told Sky News that Britain still wants the U.S.to take the lead in fighting climate change and called on individual USA states to keep making progress on that front.
"And as soon as possible, president Trump should act on, and keep, his campaign promise".
He has previously said he wanted to pull out of the deal and has called the science behind climate change into question. Such an assertion stands in defiance of broad scientific consensus.
The head of the Environmental Protection Agency Scott Pruitt, who met with Trump on Tuesday, has overtly advocated quitting a deal he judges "bad" for America.
The official told reporters that the European Union and China will also "spell out" how they plan to meet their commitments to the landmark worldwide accord to fight global warming at talks in Brussels on Friday.
The US committed to reducing carbon emissions by 26-28% in a decade in signing onto the agreement.
In less than a decade solar energy will be more cost effective than coal and natural gas in the United States.
There have been influential voices urging Trump not to ditch the Paris accord.
Hundreds of high-profile businesses have spoken out in favor of the deal, including Apple, Google and Walmart.
Fossil fuel producers including Exxon Mobil, BP and Shell have also said the United States should abide by the deal.
The U.S.is the second biggest emitter of greenhouse gases and without Washington's commitment, the world will likely miss already tough targets on curbing emissions.
