In a copy of a joint communique following a weekend meeting of the world's seven largest advanced economies, the G7 said: "We reaffirm the collective developed countries goal to jointly mobilise $100 billion/year from public and private sources, through to 2025, in the context of meaningful mitigation actions and transparency on implementation."

"Towards this end, we commit to each increase and improve our overall international public climate finance contributions for this period and call on other developed countries to join and enhance their contributions to this effort."
