Samoa is encouraging people to plant trees, compost and mulch to help offset carbon emissions caused by the Small Islands Developing States conference being held there in a month.
The Offset Islands campaign is being led by the Women in Business Development executive director, Adimaimalaga Tafuna'i.
She says there will be a sharp spike in carbon emissions which must be offset.
"There's going to be over 3,000 people coming to this UN conference. With all the travel, all the food we are going to be importing to feed them, it's going to be lots and lots of carbon emissions. As a small island country we need to be doing something ourselves."
Adimaimalaga Tafuna'i says a website has been set up for people to upload their activities, and a tally of the trees, composting and mulching efforts will be added up to see how much carbon has been offset.
She says the government has put in other green measures such as a solar-powered conference centre and is working out the best way to manage waste.
