Donald Trump announces his decision that the US will withdraw from the Paris Climate Agreement.

Highlights Pull out aligns US with Syria and Nicaragua as only non-participants

US was one of 195 nations that agreed to Paris accord in 2015

'We're getting out,' Mr Trump said

President Donald Trump announced Thursday afternoon that he is withdrawing the United States from the landmark Paris climate agreement , a move that honors a campaign promise but risks rupturing global alliances and disappointing both environmentalists and corporate titans.But Trump said he would seek to negotiate a new climate deal that is, in his view, "fair" to America's interests."In order to fulfill my solemn duty to protect America and its citizens, the United States will withdraw from the Paris climate accord but begin negotiations to reenter either the Paris accord or an entirely new transaction on terms that are fair to the United States, its businesses, its workers, its people, its taxpayers," Trump said."We're getting out," he added, "but we will start to negotiate and we will see if we can make a deal that's fair. If we can, that's great. If we can't, that's fine."Trump argued that the Paris agreement would "punish" the United States and instituted "onerous energy restrictions" that would stymie economic growth, especially in manufacturing industries. The president claimed that meeting the accord's greenhouse gas emission standards would cost the United States close to $3 trillion in lost gross domestic product and 6.5 million industrial jobs.The U.S. exit from the climate pact could raise doubts about the commitment of the world's largest economy to curbing global warming and make it more difficult to hold other nations to their environmental commitments.All but two countries - Nicaragua and Syria - signed onto the 2015 accord, which was a signature diplomatic achievement for President Barack Obama.Trump was preparing to make his decision official in remarks from the Rose Garden at the White House. The atmosphere was celebratory, with a military band performing "Summertime" and other jazz hits as Cabinet members, White House staffers, conservative activists and other Trump supporters took their seats in the garden under the warm sun.The Paris agreement has long divided the Trump administration, with the president taking much of the spring to make up his mind amid an intense campaign by both sides to influence his decision.Secretary of State Rex Tillerson and Ivanka Trump, the president's daughter and adviser, are among those who urged him to stay in the deal, arguing it would be beneficial to the United States to remain part of negotiations and meetings surrounding the agreement as a matter of leverage and influence.White House chief strategist Stephen Bannon and Environmental Protection Agency Administrator Scott Pruitt pushed for a withdrawal, which probably can't actually be finalized until near the end of Trump's term.They, along with other hard-line conservatives, have sought to convince Trump that meeting the terms of the agreement would be harmful to the bottom lines of U.S. businesses and would jeopardize manufacturing jobs, especially in the Midwest and other regions where Trump found deep support in last year's election.Introducing Trump at the Rose Garden, Vice President Pence said the climate decision was an example of the president putting what he sees as the interests of the United States above all else."Our president is choosing to put American jobs and American consumers first," Pence said. "Our president is choosing to put American energy and American industry first. And by his action today, President Trump is choosing to put the forgotten men and women first."Condemnations of Trump's decision from environmental leaders as well as Democrats on Capitol Hill arrived quickly Thursday afternoon."This decision shows a stunning disregard for the well-being of people and the planet," said Andrew Steer, chief executive of the World Resources Institute. "President Trump will now have to answer for walking away from one of the most hard-fought and popular global achievements in recent memory."Sen. Sheldon Whitehouse, D-R.I., who regularly speaks from the Senate floor about the perils of global warming, said Trump was "betraying the country.""Ignoring reality and leaving the Paris Agreement could go down as one of the worst foreign policy blunders in our nation's history, isolating the U.S. further after Trump's shockingly bad European trip," Whitehouse said in a statement. "Trump is betraying the country, in the service of Breitbart fake news, the shameless fossil fuel industry, and the Koch brothers' climate denial operation. It's sad."Gina McCarthy, Obama's EPA administrator when the Paris agreement was negotiated, said in a statement, "It's a disappointing and embarrassing day for the United States.""This decision makes zero sense from a public health or an economic perspective," McCarthy continued. "It's contrary to science and his obligation to protect America's kids and future generations. It's contrary to investors and CEOs saying we need to lean in on climate action, not bury our heads in the sand. And it's contrary to... the vast majority of Americans calling for our country to do more."More than 190 nations agreed to the accord in December 2015 in Paris, and 147 have since formally ratified or otherwise joined it, including the United States - representing more than 80 percent of the world's greenhouse gas emissions.It's also heavily backed by U.S. and global corporations, including oil giants Royal Dutch Shell, ExxonMobil and BP. Large corporations, especially those operating in international markets, have had years to get used to the idea that there are likely to be reductions on carbon emissions, and they have been adapting their businesses accordingly for some time.Withdrawing the United States from the agreement could take years due to the accord's legal structure and language, but such a move would weaken its goals almost immediately. The United States is the world's second-largest greenhouse gas emitter and would otherwise have accounted for 21 percent of the total emissions reductions achieved by the accord through 2030.The Paris agreement is designed to set the world on a path toward keeping the warming of the planet "well below" a 2 degrees Celsius (3.6 degrees Fahrenheit) rise above preindustrial temperatures, an amount of warming that scientists would consider "dangerous" climate change.Hans Joachim Schellnhuber, a physicist who founded the Potsdam Institute for Climate Impact Research in Germany, said that the United States departing from the deal could make the planet a few tenths of a degree Celsius warmer, based on the assumption that the world carries ahead with its plans while the United States keeps on emitting greenhouse gases as usual. But he emphasized that's still a significant increase - especially if the goal is ultimately to hold the planet to an even more ambitious 1.5 degree Celsius, another target cited in the Paris agreement."It would mean the remaining distance between the guardrails and where we stand right now would be halved by the U.S. contribution," Schellnhuber said. "And this is significant, because it's a narrow escape anyway."Schellnhuber says he thinks that other countries would not follow the United States out of the accord, and instead are likely to keep on pushing to cut their emissions, meaning they may be able to offset the United States' departure from the agreement.But the diplomatic repercussions of a U.S. withdrawal could be vast, as demonstrated when European leaders last week pushed Trump to stay in the climate deal at the G-7 meeting in Italy. Trump appeared unswayed, and a communique coming out of the meeting pointedly failed to include the United States among G-7 countries backing the agreement.Some environmentalists warned that pulling out of the deal will be disastrous.

"If Donald Trump pulls the United States out of the Paris Agreement he will be committing a traitorous act of war against the American people," Billionaire environmental activist and mega-political donor Tom Steyer said in an earlier statement. "Trump has abdicated American leadership and sent a clear message to both our allies and enemies alike: In the search for courageous and moral solutions to the challenges of the 21st century, don't count on America to lead."
