Separately, Germany said the USA was "harming" the entire planet, and European Commission President Jean-Claude Juncker called the decision "seriously wrong".
Trump said that he would begin negotiations to re-enter the agreement or establish "an entirely new transaction" to get a better deal for the U.S. But re-entry was hardly a priority, he suggested: "If we can, great".
"With cost estimates as high as $750 billion, the Paris agreement imposes an extremely expensive burden without moving the needle on greenhouse gas emissions". Specifically, under the deal, countries promise to try to keep temperatures no more than 2 degrees above pre-industrial age norms by committing to reducing greenhouse gas emissions to help slow rising temperatures around the world.
Under former President Barack Obama, the USA had agreed to reduce emissions to 26 percent to 28 percent of 2005 levels by 2025 - about 1.6 billion tons.
It's not something that would happen overnight.
Withdrawal only takes effect one year after notification of withdrawal. And he wouldn't face any penalty for withdrawing since the agreement is nonbinding.
"While we can all agree that we should continually work to minimize our impact on the environment through innovation and technology, this flawed deal is unfair to American workers and puts our country at an economic disadvantage to the benefit of countries like China, Iran, and India". That means making smart investments in clean energy development, holding big polluters accountable, and increasing the resilience of critical infrastructure from extreme weather and climate-related impacts.
Prime Minister of Denmark Lars Rasmussen said it was a "sad day for the world".
"We've looked at recent developments in China and India, and they are actually overcompensating for the potential increase in emissions in the USA", he said. And less than a third support measures like the Clean Power Plan - Obama's principal tool for meeting America's Paris climate commitments. It's an economic decision for them. Wind is now cheaper than coal in Colorado.
"Confronting climate change and reducing greenhouses gasses will take an global effort".
Leaving the agreement is largely symbolic, Boykoff said. Trump promised during his campaign to bring back coal mining jobs.
"It is important to have this strong, coordinated, cooperative stance at the USA federal level in order to more capably meet our emissions reductions at all levels ...", Boykoff said.
What would withdrawal mean for climate efforts overseas?
In the wake of the decision to leave the Paris Accord, "we need to be really clear - rather than just walking away from it - what you put in place in the United States", Dudley told the network from St. Petersburg, Russia.
"Withdrawing from the Paris Climate Agreement and abdicating America's leadership role in the world is a historic mistake".
Trump's pledge to move the U.S. Embassy in Israel to Jerusalem remains unfulfilled, at least for now.
West Virginia Coal Association Senior Vice President Chris Hamilton said USA withdrawal from the Paris accord would build confidence in US mining and industry even if it wouldn't make major changes on the ground. It has overtaken the U.S.in transitioning to renewable energy, generating a fifth of its electricity from renewable sources.
"The Canadian government should implement the pan-Canadian framework on climate change, and work with US states, other like-minded allies in the USA, and climate champions from around the world to further propel the clean energy revolution and show continued leadership on climate change". Trump has threatened to slash worldwide climate funding - which was a condition for poor countries to sign onto the deal.
Trump's decision has made many world leaders unhappy, especially captains of industry and various business groups distanced themselves from the White House on Thursday.
