Washington, August 5 (RHC)-- The United States has officially informed the United Nations that it will pull out of the 2015 Paris climate accord two months after President Donald Trump announced his decision to do so.

The announcement came in a document issued Friday by the U.S. State Department, which also added that Washington would still take part in future climate change talks. The statement said that future engagements aim to “protect U.S. interests and ensure all future policy options remain open to the administration,” adding the participation includes constant negotiations pertaining to “guidance for implementing the Paris Agreement."

In June, Trump claimed that the deal was "unfair" to American workers and said it stifled production and imposed burdens on the country. He has taken a hard stance on climate change; at times calling it a hoax by China. During the election campaign, he vowed to "cancel" the Paris agreement within 100 days of becoming president on January 20 in order to bolster U.S. oil and coal giants, which bankrolled his campaign.

The Paris Agreement went into effect on November 4, 2016 and has been signed by 197 countries, of which 135 have now formally ratified it, which represent more than 75 percent of global greenhouse gas emissions.
