When he made the announcement, Mr Trumpsaid the deal would hurt the USA economy.
Experts said the groundswell of support from the private sector, big states such as NY and California, and state and local leaders for the voluntary emissions-curbing commitments in the 2015 deal could even help the United States reach its goals earlier than planned.
He know "the United States has to be responsible for it and that's what we're going to do", said Nikki Haley. "He knows that the USA has to be responsible with it, and that's what we're going to do". That's the kind of thing Trump does best: executive grandstanding. He "knows that it's changing and that the USA has to be responsible for it and that's what we're going to do", she said.
In his Rose Garden speech to announce America's withdrawal, Trump said his administration hoped to "begin negotiations to re-enter either the Paris accord, or a really entirely new transaction with terms that are fair to the United States".
In a June 1 speech in the White House Rose Garden that was littered with falsehoods, the president announced that the US would immediately cease all implementation of the climate accord and "the draconian financial and economic burdens the agreement imposes on our country". The US decision to walk away from a hard-fought diplomatic achievement will make it all that more hard for the US to be seen as a reliable foreign partner, even among its closest allies.
Three days after Donald Trump announced that the USA would pull out of the Paris climate accord, senior members of his administration could not present a united front in response to questions about the president's beliefs on climate change.
"The focus has been on whether Paris was good or bad for the country", Pruitt responded when a reported asked if he believed in global warming.
The president provoked widespread condemnation when he announced the U.S. would withdraw from the Paris climate change agreement.
But nothing in the Paris accord stops the US from building coal plants to keep up with China or India.
Pittsburgh, once known not just as a powerhouse steel producer but as one of the most polluted cities in the country, will work to convert its city vehicle fleet to hybrid and electric vehicles and to make its buildings more energy-efficient, said Peduto.
"When Donald Trump says, well, we're going to negotiate a better deal, you know, he's going to go out and find a better deal?"
At least 211 mayors have adopted the Paris goals for their own cities since Trump's announcement on Thursday, and at least 17 governors have released individual statementssaying they stand by the Paris deal, agreed in late 2015 by every country in the world except Syria and Nicaragua.
Since the 1990s, the worldwide community has been engaging in forging collective actions on climate change.
Trump may not have the sense to lead our country to a greener, cleaner environment. Developed countries make a pledged contribution to the fund, which will go towards preparing developing nations for climate change and helping them keep their greenhouse gas emissions low.
China, the European Union and India, which along with the United States make up the four biggest emitters of carbon dioxide, ehave restated their commitment to the accord. "That's the reason it put us at an economic disadvantage internationally".
