Celebrate Islands is an annual event that recognises and celebrates small islands across the world. The event provides small islands with an opportunity to share initiatives, put forward management and conservation actions and find financial support for them.

In 2022, Blue joined the Conservatoire du Littoral (French Coastal Conservation Agency), the French Facility for Global Environment (FFEM) funds, and The Rhone-Mediterranean-Corsica Water Agency, to organise the 9th edition of Celebrate Islands.
