Negotiators at the UN Climate Change Summit in Paris are frantically trying to reach a global agreement to curb climate change on Saturday; a day later than expected.
“Things are moving in the right direction,” said French Foreign Minister, Laurent Fabius, who is chairing the summit.
But more compromise is needed if an agreement is to be reached, analysts said.
There is a widespread expectation that the deal would be signed on Friday, though the timings are uncertain.
Delegates worked throughout the night on a draft version to iron out the key barriers to an agreement.
Participants at the summit have been working on a draft text, prepared by the French presidency, since Wednesday.
This was seen as a significant moment after discussions that began in 2011 for a new global agreement that would stake out a long-term strategy for dealing with climate change.
Any deal signed in Paris will come into effect in 2020.
