Leaders of the Commonwealth countries called Saturday for a legally binding international agreement on climate change and a global fund with billions of dollars to help poor countries meet its mandates.
The 53-nation meeting was the largest gathering of international leaders before next month's global climate summit in Copenhagen.
The leaders said a deal should be adopted no later than next year and the support money should be available simultaneously, providing up to $10 billion a year starting in 2012.
At least 10 percent of the fund should be dedicated to small island and low-lying coastal nations that are at risk of catastrophic changes from global warming, the group said.
"Climate change is the predominant global challenge," the Commonwealth leaders said in a joint declaration. "For some of us, it is an existential threat."
The document called for a "legally binding" agreement by the world's nations.
Danish Prime Minister Lars Loekke Rasmussen and U.N. Secretary-General Ban Ki-moon, making rare appearances at a Commonwealth meeting to help drive the climate discussion, portrayed the joint declaration as further evidence of growing momentum for next month's summit.
"I will leave Trinidad fully convinced that it will be possible to reach an ambitious agreement in Copenhagen," Loekke Rasmussen told reporters after the Commonwealth leaders issued their statement following a private meeting.
Some 90 countries have now agreed to attend the summit in Denmark.
The Commonwealth countries, which represent about a third of the world's population, said in the statement that the members all agreed on the need for an ambitious program to reduce the risks of climate change.
But they added that they have a "range of views" on whether the average global temperature increase should be constrained to below 1.5 degrees Celsius or to no more than 2 degrees above pre-industrial levels.
