Statement acknowledges US pulling out, but emphasizes commitment to cause
Recognizing the US had withdrawn from the Paris Agreement, world leaders reiterated the accord was "irreversible". A statement said US would "endeavour to work closely with other countries to help them access and use fossil fuels more cleanly and efficiently".
Most leaders expressed hope the US would return to the Agreement, including UK PM Theresa May.
French President Emmanuel Macron said he would "never despair of convincing (Trump) because I think it's my duty".
However, German Chancellor Angela Merkel remained skeptical. "I think it's very clear that we could not reach consensus," she told reporters.
What else happened at the summit?
It was Trump and Putin's first meeting on the sidelines of the summit. They discussed allegations of Russian hacking during the 2016 elections, but Trump accepted Moscow's assurance it never intervened. Trump also talked to Chinese President Xi jinping: they discussed North Korea's nuclear plans.
Signs of a move away from the current G20 approach
The G20 summit this time was more like G19+1, with Trump's active "America first" policy visible in all sectors. Trump also cancelled his own press conference on July 8, making the division starker.
Another point was trade. With a little nudge from Trump, a communiqué against protectionism being renewed, for the first time, focused on countries' right to protect their markets.
