A spokesperson for Greenpeace in the Pacific says the Copenhagen conference has produced little for countries in the region who are on the frontline of climate change.
Pacific countries, as members of the Alliance of Small Island States, had been calling for a legally binding agreement that limited world temperatures to 1.5 degrees above pre-industrial times.
Instead a US-led accord set a 2 degree temperature target and failed to set any deadline for making the agreement legally binding.
The political advisor for Greenpeace in the Pacific, Feni Nabou, says that means climate change will wreak more havoc in the region.
"We don't have the luxury of time, we can save our islands but it just become a whole lot harder. We thought when political leaders came together at Copenhagen they would make the political decisions that needed to be made, but they obviously did not."
Feni Nabou says Greenpeace will work with other members of civil society in the Pacific to apply more pressure on politicians to act.
