The U.S. officially rejoined the Paris Agreement on Friday.
On his first day in office, President Joe Biden signed an executive order that set the country on track to rejoin the global accord—and after 30 days, the nation finally had formally reentered the agreement.
However, Special Envoy for Climate John Kerry stressed at an event that there is still more work to be done.
“We know that just doing Paris is not enough,” Kerry said. “If every country delivered, we’d still see a warming planet Earth.”
Under the Paris deal, the world’s countries agree to limit the planet’s warming to less than 2 degrees Celsius above pre-industrial levels, with the further goal of limiting warming to 1.5 degrees.
The Trump administration pulled the U.S. out of the agreement, arguing that it was burdensome for business and workers.
However, Biden stressed that he sees an opportunity for jobs as the country moves toward clean energy. He has also argued that climate change is among several crises the country currently faces.
“This is good news for the United States and for the world,” United Nations Secretary-General António Guterres said during remarks at an event with Kerry.
“For the past four years, the absence of a key player created a gap in the Paris agreement, a missing link.”
Kerry will be leading the Biden administration’s climate diplomacy, including at a UN conference set for November in Scotland, where countries will formally adopt more stringent climate commitments.
Biden administration officials have said that they will announce updated goals before a summit on Earth Day this year.
