The decision amounts to a rebuttal of the worldwide effort to pressure Trump to remain a part of the agreement, which 195 nations signed onto. Foreign leaders, business executives and Trump's own daughter lobbied heavily for him to remain a part of the deal, but ultimately lost out to conservatives who claim the plan is bad for the United States."We're getting out. And we will start to renegotiate and we'll see if there's a better deal. If we can, great. If we can't, that's fine," he added.In triggering the official withdrawal procedures, Trump will spark a lengthy process that won't conclude until November 2020 -- the same month he's up for reelection, ensuring the issue becomes a major topic of debate in the next presidential contest. "The United States will cease all implementation of the nonbinding Paris accord," Trump said, saying it would include ending the implementation of carbon reduction targets set under Obama and ending contributions to the United Nations' Green Climate Fund.
