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.

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.

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.
