A target to keep global temperature rises "well below" 2C above pre-industrial levels and limit the impact to 1.5C has been outlined in the final draft agreement at the Paris climate change conference.
French foreign minister Laurent Fabius said the conference had come up with "an ambitious and balanced agreement" which was "necessary for the entire world".
He said the agreement, if adopted, should make it possible to reduce the risks and impacts linked to climate change.
"If adopted, this text will mark a historic turning point," Mr Fabius told delegates at the conference in the French capital on Saturday.
He said that every five years there would be a "collective stock take" of progress made towards the targets set in the legally-binding agreement.
"The world is holding its breath," Mr Fabius. "It counts on all of us."
