The negotiators, who have been in the Peruvian capital for about two weeks, are grappling to prepare the elements of the draft due to the logjam between developing countries and industrialized nations that haggle over the formula of sharing the burden for cutting emissions, and who should pay.

Peruvian Environment Minister Manuel Pulgar-Vidal, who presides over the talks, was seemingly frustrated by the lack of progress and called for constructive exchanges.

Vadal said "We don't want to leave Lima with empty hands... We are in a time in which we should take decisions."

"We are almost there. We just need to make a final effort. Finding a solution would be a way to show to the world that we are building this process step by step," he said.

The climate talks are aiming to establish the draft text of a new international climate change agreement to be signed by all countries at the next major talks in Paris in 2015.

India is demanding that the key issue of adaptation must be fully reflected in the new climate agreement and developed nations should give enough carbon space to developing nations to achieve sustainable growth.
