Climate change

The climate crisis affects every member of the Commonwealth. The Commonwealth Secretariat helps member states tackle climate change and adapt to its worst impacts.

Climate change negatively affects the development of small and other vulnerable countries across the Commonwealth. Many Commonwealth countries are already facing increased temperature, sea level rise, storm surges, drought, floods, and hurricanes. The Commonwealth supports small and other vulnerable states by amplifying their calls for greater climate action.

We have been pushing for greater climate action since 1989, when Commonwealth leaders committed to protecting the environment in the Langkawi Declaration. This was one of the world’s first collective statements to name greenhouse gas emissions as one of the leading problems facing the planet.

Climate finance

The Commonwealth helps small and other vulnerable states access the money they need to adapt to or prepare for the impacts of climate change through the Commonwealth Climate Finance Access Hub.


The Commonwealth is a partner in the CommonSensing project. The project aims to build climate resilience in vulnerable pacific countries like Fiji, Solomon Islands and Vanuatu, and enhance climate action decision-making using satellite remote sensing technology.
