United Nations members have agreed on a deal to tackle climate change at a summit in the Peruvian capital Lima.
The deal asks countries to submit national plans on how they will deal global warming early next year ahead of a crucial summit in Paris.
Developing countries, including China and India, had expressed concern at earlier drafts that they claimed could impose too heavy a burden on emerging economies.
But agreement was finally reached with the final draft saying countries have "common but differentiated responsibilities" to deal with global warming.
"As a text it's not perfect, but it includes the positions of the parties," Peru's environment minister Manuel Pulgar-Vidal said.
Britain is set to pledge hundreds of millions of pounds to a United Nations "green bank" intended to help poor countries prepare for the impact of global warming.
The announcement is expected at a pledging conference in Berlin on November 20, after Prime Minister David Cameron said the UK would "play a very positive part" in supporting the Green Climate Fund.
No specific figure has yet been confirmed for the UK's contribution, but energy minister Amber Rudd said earlier this month that Britain will donate "strongly" to the fund.
Speaking at the G20 summit, Mr Cameron stressed that the money will come from funds already earmarked for international development and does not represent a new financial commitment.
