Negotiators at the Paris summit aim to wrap up a global agreement to curb climate change on Saturday – a day later than expected.

“We are nearly there. I’m optimistic,” said French Foreign Minister Laurent Fabius, who is chairing the summit.

UN Secretary General Ban Ki-moon said the negotiations were the “most complicated, most difficult, but, most important for humanity”.

Mr Fabius told reporters in Paris that he would present a new version of the draft text on Saturday morning at 0800 GMT, which he was “sure” would be approved and “a big step forward for humanity as a whole”.

“We are almost at the end of the road and I am optimistic,” he added.

The summit is entering a final push to try to secure a global agreement that would stake out a long-term strategy for dealing with climate change. However, there are still some unresolved issues.
