"Our common endeavor is to build the foundation of renewed trust, both towards our governments and among our countries", their communique states.
The president focused on fighting terrorism and increasing military spending in a speech to US troops at a base in Sicily, Italy Saturday.
Although Trump tweeted "I will make my final decision on the Paris Accord next week!" as he headed back to Washington DC over the weekend, Axios and Breitbart News reported on Sunday that he has already told several aides, including Environment Protection Agency (EPA) Administrator Scott Pruitt, that he meant to withdraw the U.S. from the agreement despite pressure from other G7 partners not to quit.
Leaders warned the US president that he risks a stampede, as others in the 195-nation agreement use American withdrawal from the treaty to reduce their own commitments. While US president Donald Trump backed a pledge to fight protectionism he refused to endorse a major accord on climate change.
The meeting's final declaration reflected a stalemate between the United States and the six other participating countries, who are all strongly committed to the Paris accord. Cohn stressed Friday that the president was simply being critical of the US trade deal with Germany. The United States emits the most heat-trapping greenhouse gases after China. "Why they see North Atlantic Treaty Organisation as a threat is beyond me", he said.
"It seems doubtful that a trade minister or arms control negotiator would really drive a harder bargain or walk away from a deal because of such considerations", Philip Wallach, a senior fellow Brookings Institution, told The Daily Caller News Foundation.
President Trump has come under some pressure from the other world leaders to honor the 2015 Paris Agreement on curbing Carbon (C) emissions, he has called global warming a hoax. However, Mr Trump wants to boost coal production to create more jobs.
"I think he is learning to understand the European position", Cohn said when asked which way the president was leaning on the Paris agreement.More news: Mercedes Now the Underdogs: Wolff
Merkel left the summit telling reporters that the climate talks in particular were "very unsatisfactory". "The UK remains committed to this agenda".
Perhaps the most historic global agreement on climate change is about to lose a member.
"Terrorism is a threat, bad threat to all of humanity", Trump said, standing in front of a massive American flag at Naval Air Station Sigonella.
The Paris deal is the world's first comprehensive climate agreement, set out in 2015, with the aim of keeping the global average rise in temperatures below 2C.
The stalemate on climate change was mirrored by divisions between the United States and the other G7 countries over trade and migration at the annual summit, described by officials as the toughest in years.Delegates worked long into the night in an attempt to reach a compromise on the closing statement to be issued later Saturday.
"In this context, we all agree on the importance of supporting developing countries".
This includes requirements that all Parties report regularly on their emissions and on their implementation efforts.
There will also be a global stocktaking every five years to assess the collective progress towards achieving the objective of the Agreement and to inform further individual actions by Parties.
