The United States of America on Friday officially re-entered the Paris Climate Agreement, nearly one month after President Joe Biden took office and immediately pledged to re-enter the deal.
“Now, as momentous as our joining the Agreement was in 2016 and as momentous as our rejoining is today what we do in the coming weeks, months, and years is even more important,” Secretary of State Antony Blinken said in a statement.
“Climate change and science diplomacy can never again be ‘add-ons’ in our foreign policy discussions,” Blinken added.
The Paris agreement was negotiated during the Obama administration’s final term in office, when Biden was vice president.
Former US President Donald Trump took the US out of the accords in 2017, arguing that it put too many limits on what US businesses could do.
The Paris agreement’s long time lag meant that the US did not formally exit the deal until November 2020.
The US is the only country out of the 196 signatories to have left the agreement.
It is also the world’s largest contributor of carbon emissions.
Biden, however, is a vocal advocate for multilateral agreements and diplomacy, and he has signalled that climate change is an issue he takes seriously.
He named former secretary of state John Kerry as his special envoy for climate change, and gave him a role on the US National Security Council.
Re-entering the agreement was one of his first moves as president.
