"The United States has a terrific record on reducing our own greenhouse gas emissions".

California, New York and Washington, which have formed their own alliance, represent more than one-fifth of U.S. gross domestic product and account for at least 10 per cent of greenhouse gas emissions in the United States, their governors said.

Nicaragua and Syria are the only countries not party to the Paris accord; the former says it is not ambitious enough.

"The two leaders agreed to exchange views on the initiatives on climate change that will be taken in the coming weeks", it said, without elaborating.

In a separate development on Friday, Macron spoke with Pope Francis, "thanking him for. his mobilisation for the Paris Agreement", the presidential office said. Barbara Hendricks said other countries will fill the leadership void left by the United States but none will be expected to make up the shortfall in emissions reductions caused by Washington's exit.
