Despite uncertainties over whether the United States will remain committed to the Paris climate accord under President Donald Trump, envoys convened talks on Monday in Germany on implementing the details of the deal to combat global warming.

During 10 days of talks in Bonn, officials will try to agree on how to implement the 2015 Paris Agreement to cut carbon emissions, a treaty that former U.S. President Barack Obama’s government played a leading role in forging.

The accord calls for limiting the global average temperature increase since the industrial revolution to 2°C (3.6°F ) or less a goal that has been called ambitious.

Patricia Espinosa, head of the U.N. Framework Convention on Climate Change that is hosting the Bonn talks, said it was important to make progress on the nuts and bolts of the agreement before November’s annual climate summit. Her agency’s budget is also up for discussion.

Ms. Espinosa refused to comment on the impact of a possible U.S. withdrawal from the talks or even the entire climate change accord. “I would rather wait until a decision has been taken,” she said.

The White House postponed a meeting that was planned on Tuesday to discuss whether to withdraw from the Paris deal that Mr. Trump has said he would “cancel” or find a way to back away from emissions targets set by the Obama administration.

Fiji, which holds the presidency of the coming climate summit, said it was important to press ahead with the talks.

“Irrespective of the position of particular countries, I think it’s very important that we continue to move this process forward,” said Fiji envoy Nazhat Shameem Khan. “That’s the short answer to the issue about the United States.”
