Leaders of 19 nations at the G20 summit in Hamburg, Germany, have renewed their pledge to implement the Paris deal on climate change, despite the US pulling out.

Deadlock over the issue had held up the last day of talks in Hamburg but a final agreement was eventually reached.

The final agreement acknowledges President Donald Trump’s withdrawal from the Paris climate agreement without undermining the commitment of other countries.

The compromise comes after violent protests in the host city.

The joint summit statement released on July 8 said: “We take note of the decision of the United States of America to withdraw from the Paris Agreement.”

However, the leaders of the other G20 members agreed the accord was “irreversible”.

The statement also said the US would “endeavor to work closely with other countries to help them access and use fossil fuels more cleanly and efficiently”.

President Trump has pledged to help the US coal industry make a comeback and has previously characterized the Paris agreement as aiming to disadvantage his country’s workers.

In press conference as the two-day summit drew to a close, German Chancellor Angela Merkel said she still deplored President Trump’s position on the Paris accord but she was “gratified” the other 19 nations opposed its renegotiation.

As well as insisting on the inclusion of separate America-only paragraphs in the final text, Donald Trump canceled his own scheduled news conference on July 8, reinforcing the image of the G20 as the G19 + 1.

“I think it’s very clear that we could not reach consensus, but the differences were not papered over, they were clearly stated,” Angela Merkel told reporters.

Angela Merkel said she did not share the view of UK Prime Minister Theresa May that Washington could decide to return to the climate agreement.

However, Theresa May reiterated her belief that the US could rejoin the accord in her news conference on July 8.

French President Emmanuel Macron also remained hopeful of persuading President Trump to change his mind, saying: “I never despair of convincing him because I think it’s my duty.”

Emmanuel Macron announced that Paris would host another summit on December 12 to make further progress on the climate agreement and to address financing.

There have been large protests in the city, with demonstrators and armed police clashing into the early hours of Saturday.

Demonstrators – who were protesting against the presence of Donald Trump and Vladimir Putin, climate change and global wealth inequalities – set fire to vehicles and barricades, threw rocks at officers and looted shops.

At one point, police chased protesters across rooftops while officers on the streets used water cannon on protesters.

Nearly 200 police officers were injured during the protests. Dozens of protesters have been detained.
