COP21 talks to continue into the weekend
The third draft of a possible agreement will only be released on Saturday.
Negotiators from nearly 200 countries worked through the night on the second version of a global climate deal, expected to be the first universal accord to combat climate change and its effects.
The latest document is 27 pages long, two down from the last, and contains just 50 square brackets or options to choose between, down from over 350.
Delegates believe it's the final stretch and some decisions have already been made.
There's agreement to cap global warming at two degrees Celsius and to pursue efforts to make that 1.5.
Countries will come together to do a global stocktake of where they are in 2019, then 2023 and then every five years.
The long-term goal is to reach greenhouse gas neutrality in the second half of this century.
Questions remain around finance and support for the most vulnerable countries.
Negotiators have submitted their feedback and a new draft will be out on Saturday morning.
