The american president announced the withdrawal of his nation of the June 2017 accord, claiming that it “punished” the US coal industry and risked countless jobs.
The move has sparked consternation among many world leaders and climate change activists.
However, the withdrawal did not officially take place until early this month.
The historic 2015 agreement, minted under President Obama, aims to keep the global temperature rise this century “well below” 2 ° C above pre-industrial levels and to continue efforts to limit further temperature rise at 1.5 ° C.
Speaking at the G20 World Leaders’ Meeting – hosted virtually by Saudi Arabia, Mr Trump said: “To protect American workers, I pulled the United States out of the Paris agreement on the unjust and one-sided climate – a very unjust act United States.
“The Paris agreement was not designed to save the environment, it was designed to kill the US economy.
“I refused to give up millions of American jobs and send billions of US dollars to the world’s worst polluters and environmental offenders.
However, the president also said that his administration had made “environmental stewardship” a “sacred obligation”.
He said the United States has made significant progress over the past four years to ensure that the country has “the purest air and water on the planet.”
Mr Trump’s actions and justification for leaving the deal were rejected by US President-elect Joe Biden, who said he would join the deal as soon as he took office.
The president remains in charge of the United States for the next two months, until Mr. Biden’s scheduled inauguration on January 20.
His various court challenges over the election result – where he claims a criminal act without providing evidence – have so far proved unsuccessful.
