He said his major concern is that the agreement is not enforceable, and that Russia, Brazil, India and China would fail to curb their growing greenhouse gas emissions.
The European Union's top climate change official, Miguel Arias Canente, said in a statement that Trump's decision to leave the Paris accord made it "a sad day for the global community", adding that the bloc "deeply regrets the unilateral decision". "This is an unprecedented forfeiture of American leadership which will cost us influence, cost us jobs, and invite other countries to walk away from solving humanity's most existential crisis". A source close to the matter said Trump was preparing to pull out of the agreement.
Italy, France and Germany said on Thursday they regret the United States decision and dismissed the suggestion that the global pact could be revised.
Mr Bainimarama said as incoming president he'll do everything possible to accelerate the momentum by "forging a grand coalition of governments, civil society, the private sector and ordinary people".
During his speech announcing the United State's plan to withdraw from the Paris Agreement, President Trump mentioned Pittsburgh, Pennsylvania saying, "I was elected by voters of Pittsburgh, not Paris".
"As President, I can put no other consideration before the wellbeing of American citizens", he said.
"We're getting out but we will start to negotiate and we will see if we can make a deal that's fair", he said. California Governor Jerry Brown called Trump's decision possibly "tragic" and a step "backwards" for the US.More news: Pep Guardiola vows Manchester City will come back stronger next season
Johnson claims the Paris agreement forces the U.S.to rely on more expensive, alternative energy sources, driving up prices for consumers.
As you've probably already heard, President Trump announced today that he will withdrawal the US from the Paris climate agreement.
Supporters of the agreement, which include many Republican business leaders as well as environmental activists, say just the opposite - that steps to combat global warming would help the us economy by building up new industries, especially solar and wind power. He said he would seek to renegotiate the agreement - signed by more than 190 countries - in terms that would better benefit USA workers. "As of today, the United States will cease all implementation of the non-binding Paris accord and the draconian financial and economic burdens the agreement imposes on our country", Trump said.
The Kremlin spokesman said Moscow had not formed a definitive position on the issue as Trump has not announced his decision yet. The movement has lost a leader to influence the world's more reluctant nations and encourage them to aim for targets that they would not entertain voluntarily. But it remains to be seen whether they stick to their commitments on transparency and other issues that the US had been pushing for.
"At what point does America get demeaned?" he asked. On Capitol Hill, Rep. Carlos Curbelo, a Miami Republican, said a group of congressional Republicans and Democrats, largely from coastal states, will redouble its efforts to find ways to reduce the risks of climate change.
China, which has upped its environmentalism game in recent years and is the only country that emits more carbon dioxide into the atmosphere than the United States, also reacted strongly before Trump's announcement.
The move may also harm the growing US clean-energy industry, which may now see China and Europe take the lead in developing advanced technologies.
