Village leaders from Tuvalu, Kiribati, Vanuatu, Fiji and Solomon Islands have signed a declaration calling for immediate action on climate change.
A senior oceans campaigner for Greenpeace, Lagi Toribau, says a meeting was held in Port Vila last week for communities affected by Cyclone Pam to voice their concerns about climate change.
Mr Toribau says the leaders say they are tired of waiting for the international community to decide their fate.
"We got a really strong sense from the community leaders that they wanted to do more. That they are sick of waiting. I mean we are looking at the upcoming 21st COP meeting that is 21 meetings that they have had and you know what have they, what have they delivered?"
Lagi Toribau says the meeting marked the end of a 20-day relief mission by Greenpeace's flagship vessel, the Rainbow Warrior, which made 26 aid drops across 13 islands alongside 10 other aid organisations in Vanuatu.
Greenpeace and other groups are marking the 30th anniversary of the bombing of The Rainbow Warrior by French agents in Auckland in 1985.
