"This short-sighted and unsafe decision will be met by opposition around the world: from ordinary people, to scientists, and political leaders - making the United States a global outcast".
This is also reversing the strides former President Obama's administration made on climate change.
The precise mechanism for withdrawal hasn't yet been determined, and White House officials cautioned the plans could change until Trump makes his decision public.
A source briefed on Trump's plans told Reuters that Trump has chose to follow through on his campaign pledge to pull the United States out of the Paris accord, a move created to help boost domestic energy production and speed economic growth, after weeks of deliberations on the issue.
What is the Paris climate change agreement? Besides Syria and Nicaragua, who believed the deal was not strong enough, every nation signed on. Under the pact, the United States committed to reducing its emissions by 26 to 28 percent from 2005 levels by 2025. -China Climate Leaders Summit this summer are likely off the table, Boston Mayor Marty Walsh said Wednesday. Gorkov had no comment for reporters when asked about what their conversation was about.
The official, who insisted on anonymity to discuss the decision before the official announcement, said the president and his were finalizing the details of a pullout. After he returned to Washington, Trump lashed out at Merkel over other matters, including North Atlantic Treaty Organisation funding and Germany's trade deficit.
And during his recent foreign tour, officials said he opposed the accord, arguing that by implementing the self-determined mitigation goal, the United States would severely impair its manufacturing, leaving it less competitive than India and China. Other major powers, including China, have signaled they will uphold their commitments to Paris regardless of Trump's moves.
"This would be a colossal mistake", said Nick Burns, who served as under secretary of state during George W. Bush's administration. "It would also devastate our global credibility".
Trump's chief economic adviser, Gary Cohn, has discussed the possibility of changing the USA carbon reduction targets instead of pulling out of the deal completely.
A frustrated German Chancellor Angela Merkel later warned that Europe "must take its fate into its own hands", citing the differences with Washington on climate change as evidence of their divergent paths. "For President Trump to take us out, it is anti-science".
This seems particularly rich, coming after eight years of President Barack Obama.
Trump's top aides have been divided on the accord. The Fox report said Kushner was not a back channel between the Trump campaign and Russian Federation.
A senior Chinese official said China is determined to open up and reach a deal, which seen as a forerunner to a possible future free-trade accord.
Silicon Valley has had a complicated relationship with the Trump White House in its early months.
The Paris accord was agreed upon by 197 countries and so far has been ratified by 147 parties, which includes the European Union. The UNFCCC is the body underpinning all global climate negotiations, including the Kyoto Protocol (which the United States famously failed to ratify) and the Paris Agreement (which the United States is now infamously mucking up).
This is in response to today's tweet by Trump and wide reports that the POTUS, who campaigned against climate change calling it a "hoax", will withdraw the USA from arguably the most important agreement within the United Nations that seeks to reduce the world of greenhouse gas emissions. A group of 21 Republican senators wrote to him last week urging him to make a "clean break" from the agreement. But Trump campaigned on a promise to nix the deal, saying it would mean stricter environmental policies that would hobble the economy and cost jobs. If the United States withdraws from an agreement that almost 200 other countries are a part of, it would join Nicaragua and Syria as the only other countries that rejects the accord.
"Global climate change is a threat to the economy", says Mark Zandi, chief economist at Moody's Analytics.
