The Egyptian president of the UN climate conference, Sameh Shoukry, has told delegates that time is not on their side if a deal is to be concluded before the scheduled close of the conference on Friday.
There have been warnings that negotiations are progressing too slowly because of deep divisions on some central issues.
A draft agreement published on Thursday does not include directions for the launch of a loss and damage fund to assist the most vulnerable countries. 
This has been a demand of many developing nations.
Nor does the draft introduce a broad commitment to phase down all fossil fuels, rather than just coal, as has been proposed by India and the European Union.
