The other six members of the G7 - Canada, France, Germany, Italy, Japan and the United Kingdom - reaffirmed "strong commitment" to the agreement, which Barack Obama signed in 2015.
"The United States is evaluating its policy with regard to the climate, so the six other G7 countries will reaffirm their commitment (to the global Paris accord) while taking note" of the U.S. position, a French official said at the G7 summit in Sicily.
"Europe, Canada and Japan stood up today and made a stand, revealing again how far Trump is out of step with the rest of the world on climate change", Jennifer Morgan, Greenpeace's worldwide executive director, said in Sicily.
Trump tweeted that he would reveal his hand only next week as to whether he will keep the United States in the Paris accord, a global pact on curbing carbon emissions that he vowed to jettison when campaigning for the White House.
On the substance of this issue, Trump is on solid ground.
The declaration said, "Since the lack of social and economic inclusiveness and opportunities may contribute to the rise of terrorism and violent extremism, we commit to address these issues through a comprehensive approach linking together security, social inclusion, and development".
"Do you notice how much stronger we're getting, are you feeling it?" He also reiterated the USA commitment to the North Atlantic alliance.
"If we're not on the side of what's right, if we're not making the argument and fighting for it, even if sometimes we're not able to deliver at 100 percent everywhere, then it collapses", President Obama warned last November.

In 2016, the G-7 consensus on what to do about the "Migration and Refugee Crisis" was to "increase global assistance" and boost the use of orderly resettlement programs to take refugees to safety.
British Prime Minister Theresa May told reporters that the G7 leaders agreed that climate was a priority, despite the fact that Trump is still mulling over his final decision.
Six world leaders reaffirmed their commitment to the Paris accord, the world's first comprehensive deal aimed at reducing greenhouse emissions.
At the same time, several of the leaders appeared to hope this week's meeting, Trump's first, would prove a learning experience. "There are no indications whether the United States will stay in the Paris Agreement or not".
