COP21: Deal expected on Saturday, a day later than expected
Among the unresolved issues is compensation for nations most affected by climate change.
Negotiators at the Paris climate summit aim to wrap up a global agreement to curb global warming on Saturday - a day later than expected, hosts France said.
"Things are moving in the right direction," said French Foreign Minister Laurent Fabius, who is chairing the summit.
Among the unresolved issues is compensation for nations most affected by climate change.
A deal signed in Paris would come into being in 2020.
Participants at COP21 - as the UN conference is called - 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 about a new global agreement that would stake out a long-term strategy for dealing with climate change.
The latest version draft document, delivered after consultations throughout Thursday, was 27 pages - considerably shorter than previous versions.
It says that temperature rises must be kept "well below 2C above pre-industrial levels and to pursue efforts to limit the temperature increase to 1.5C".
