The U.N. Climate Change Secretariat plans to publish a list of submissions on Monday. That may put pressure on all capitals to keep their promises.
Countries accounting for at least two-thirds of emissions -- led by China, the United States and the European Union -- have all written in. Smaller emitters, from the Philippines to Mali, have also sent promises or asked to be associated with the deal.
The Secretariat says the January 31 deadline is flexible.
"Most of the industrialized countries' (promises) are in the 'inadequate' category," said Niklas Hoehne, director of energy and climate policy at climate consultancy Ecofys, which assesses how far national commitments will help limit climate change.
"The U.S. is not enough, the European Union is not enough. For the major developed countries it's still far behind what is expected, except for Japan and Norway," he said.
Some developing nations, such as Brazil or Mexico, were making relatively greater efforts, he said.
