This weekend eighteen Pacific island countries will be amongst over 165 nations involved in a global day of action to bring further attention to climate change.
They will play their part in an event called "Moving Planet", which organisers say is dedicated to solving the climate crisis by ending the world's dependence on fossil fuels.
Countries are expected to be involved in a variety of activities to heighten awareness of the impacts of climate change, such as tree planting, walks and cycle rides.
Tonga will host the dawn opening ceremony for the global event.
Tonga organiser, Polikalepo Kefu says the ceremony will be held at Popua village, deemed the country's most vulnerable village to higher sea levels.
He says opening Moving Planet is a real honour.
"We are showing the world we are doing something for the environment. Even though we are not having so much contribution to the emissions but we will soon be a victim of climate change."
