Trump, tapping into the "America First" message he used when he was elected president a year ago, said the Paris accord would undermine the USA economy, cost U.S.jobs, weaken American national sovereignty and put the country at a permanent disadvantage to the other countries of the world.
Asked about Musk's resignation, Commerce Secretary Wilbur Ross told Fox News that "anybody who read the agreement and understood it would realize that this was not really about climate, this was about U.S. money going to other countries and it didn't solve the climate problem".
After the secession became official on Thursday, a number of business leaders issued statements condemning the move. Former President Barack Obama expressed regret over the pullout from a deal he was instrumental in brokering.
"In short, the agreement doesn't eliminate coal jobs, it just transfers those jobs out of America and ships them to foreign countries", Trump maintained in remarks that did not once refer to the fact that the United States has historically been the world's biggest polluter with the largest carbon footprint in the global community, and the rest of the world, and the U.S. itself, has had to pay for American profligacy and addiction to hydro-carbons. He said, "I do respect this decision but I do think it is an actual mistake both for the USA and for our planet".
Speaking in the White House Rose Garden, Trump said the US will negotiate to either re-enter the Paris pact or join a new treaty on terms that would better suit American businesses and taxpayers. He in particular complained about China's terms under the agreement.
Oregon Sen. Jeff Merkley said on Twitter: "Trump's shortsighted, extremist strategy on #ParisAgreement threatens to put American leadership at a disadvantage for generations to come".
"One by one we are keeping the promises I made to the American people", Trump said. "They are charging ahead with developing new eco-technology".
"As the federal government abdicates its responsibility to address climate change - at the expense of our environment and economy - NY is leading the nation in advancing a clean energy future", Cuomo said in a statement.
At the G7 summit in Sicily last week, several world leaders spoke with Trump on the issue and publicly expressed hope that the United States would remain in the agreement.
Seven Social Democratic ministers in her coalition government said the United States "is harming itself, we Europeans and all the people of the world". Under the pact, which was years in the making, countries both rich and poor committed to reducing emissions of greenhouse gases generated by burning fossils fuels and blamed by scientists for warming the planet. He released the statement as President Donald Trump was speaking at the White House Rose Garden.
He said it was especially disappointing for the citizens of vulnerable nations throughout the world.
Perhaps the Steel City was a bad example.
The spokesman for U.N. Secretary-General Antonio Guterres called the action a "major disappointment".
Or he could invoke a more dramatic option and choose to pull the USA out of both the Paris accord and the larger United Nations Framework Convention on Climate Change, which the US ratified in 1992 under Republican President George H.W. Bush. The White House signaled withdrawal was likely, but Trump has been known to change his mind at the last minute on such major decisions. That country must then wait another year.
Elon Musk, the CEO of Tesla and SpaceX, announced that he's quitting the president's business advisory councils because of the decision.
To highlight the vulnerability of Small Islands', the Presidency of Fiji will convene the 2017 UN Climate Change Conference (COP23) to take place in Bonn, Germany from 6 to 17 November 2017.
Japan, Australia, New Zealand and South Korea also regretted the US move and reiterated their commitment to implement the agreement. Seated in the front row were aides who had advocated for the withdrawal, including EPA administrator Scott Pruitt and chief strategist Steve Bannon.
The Sierra Club, an environmental advocacy group, said Thursday that Trump's decision amounts to the president "turning his back on the public in every single US state". Governors and analysts cited moves including California's effort to get 100 percent of its electricity from renewable sources, northeast states potentially tightening maximum allowances for carbon and OR working on measures to put a price on carbon.
Rank and file Senate Democrats joined Schumer in opposing Trump.
The president used declining coal industry jobs as an example of his concern that the climate pledge was hurting USA workers.
In a Wall Street Journal op-ed, Rep. Kevin Cramer, R-N.D., called it "abundantly clear that the agreement, which is and will remain legally nonbinding, does not prohibit lowering the American pledge", which was set at a 26 to 28 percent emission reduction. The move would isolate the United States in a global effort to curb the warming of the planet, and leave an opening for countries like China to fill the leadership void.
"This unprecedented diplomatic feat would never have been possible without the involvement of the United States of America", she said in a statement.
During the campaign, Trump said the accord would cost the USA economy trillions of dollars with no tangible benefit. The project, funded by a $1 million donation from the bet-hedging Zurich Insurance Group, is part of a larger water management strategy the city hopes will reduce the future impacts of climate change. President George W. Bush provoked similar anger from European allies when he decided not to implement the 1997 Kyoto climate change treaty, which was ratified by 140 nations.
