WASHINGTON (AP)  President Donald Trump says the U.S. will immediately cease all implementation of Paris climate change accord standards.

Trump announced Thursday that the United States is withdrawing from the landmark 190-nation agreement to reduce earth-warming gases.

The president said that the nation would stop adhering to the emissions reductions standards immediately. The agreement was nonbinding.

Trump painted the original deal as “unfair” to American workers and taxpayers, suggesting that other countries had more favorable agreements.

He also said that the United States would be willing to re-enter the deal on “better terms.”

The leaders of France, Germany and Italy say the Paris climate accord cannot be renegotiated as President Donald Trump has demanded.

French President Emmanuel Macron, German Chancellor Angela Merkel and Italian Premier Paolo Gentiloni said in a joint statement Thursday that they take note “with regret” the U.S. decision to pull out of the 2015 agreement.

The three leaders say they regard the accord as “a cornerstone in the cooperation between our countries, for effectively and timely tackling climate change.”

They added that the course charted by the accord is “irreversible and we firmly believe that the Paris Agreement cannot be renegotiated.”

Macron, Merkel and Gentiloni say they remain committed to the deal and will “step up efforts” to support the poorest and most threatened nations.
