By abandoning the world's chief effort to slow the tide of planetary warming, Trump was fulfilling a top campaign pledge.
The day before Donald Trump pulled the United States out of the Paris climate accord, former Secretary of State John Kerry urged the president to think about the country's grandchildren in deciding the fate of the planet.
"We will see if we can make a deal that's fair". The United States now joins Nicaragua and Syria in dissent.
"Our climate action strategy represents an opportunity to attract investment, innovation and develop new green technologies", he said. But the evidence he referenced, from the pro-business American Council for Capital Formation and the U.S. Chamber of Commerce, is misleading.
The US is now one of the largest emitters of carbon dioxide in the world.
The United States' announced goal was to lower emissions 26-28 percent below 2005 levels by 2025.
Andresen hoped USA communities will not be discouraged by President Trump's decision.
Meanwhile, Trump said, Washington's commitments would cost the nation US$3 trillion "in lost GDP and 6.5 million industrial jobs". Even fossil fuel companies such as Exxon Mobil, BP and Shell say the United States should abide by the deal. "Even Mitt Romney knows this is a failure of leadership".
In a Berlin speech, Chinese Premier Li Keqiang said that fighting climate change is a "global consensus" and an "international responsibility".
Democratic senator Sheldon Whitehouse added: "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 United States further after Trump's shockingly bad European trip".
Global leaders had pressed Mr Trump not to abandon the accord. "Don't know which way Paris will go, but I've done all I can" to convince Trump to stick with USA commitments made under his predecessor, Barack Obama, Musk wrote on Wednesday in a post on Twitter.
Minister for Environment and Energy Josh Frydenberg told News Breakfast that Australia remained committed to the Paris Accord.
The president said that the nation would stop adhering to the emissions reductions standards immediately.
Trump had waffled on his decision whether to keep the U.S. committed to the landmark 2015 agreement or fulfill his campaign promise to pull out.
Jerry Brown of California and Jay Inslee of Washington, are forming a United States Climate Alliance, which will convene states that want to uphold provisions of the Paris Accord. Indeed, shifting to a clean-energy economy has greater potential to boost employment, economists say.
Nancy Pelosi, opposition leader in the House of Representatives, said the decision would be a "stunning abdication of American leadership" and "a threat to the planet".
In Trump's first 100 days in office, his administration has already approved the Keystone XL and Dakota Access pipelines, lifted a coal moratorium on public lands and moved toward opening vast areas of America's coasts to offshore drilling.
The Republican vowed at the time to "cancel" the Paris deal within 100 days of becoming president on January 20, part of an effort to bolster USA oil and coal industries. Some utilities are also responding to customer demand for renewable power, and the policies of any one administration have little impact on those decisions.
He is breaking from many of America's staunchest allies, who have expressed alarm about the decision.
The White House has told allies the 2015 deal was signed by President Barack Obama out of "desperation".
