It's 11 o'clock on Thursday night and the forestry negotiators are locked in a room behind me trying to hammer out an agreement.
By all reports it's going slowly. But only those content to settle for a 500 Megatonne loophole would say it's going well.
There is a lot of momentum at the 'technical' level. Almost everyone seems content to stitch up this deal.
There are a couple of wild cards on the table. How long will Tuvalu hold out with its principled objection? How long will the African Group hold out with its compromise? What will Ministers do? Will they rubber stamp rules that allow forestry emissions to increase without penalty?
My task now is to hang around outside this room and find out what I can when they finish. Then, we will have to react quickly to influence the political decision that will follow these technical negotiations.
