Measure how green is your island and know how to improve your scores

The GTI Observatory Global Index measures and evaluates the progress of islands around the world on their way to a greener future. One of the objective of the index is also grouping islands with similar needs to support replication of best practices, economy of scale, financing, as well as the union of forces for shared goals also in terms of legislation and policy.

Islands are ranked based on a set of sustainable objective criteria and evaluated by a panel of independent experts. Promoting your island as a green destination is one of the benefits of taking part in the GTI Global Index.

The GTI drop system is used to highlight and rank the sustainability score of islands. Only the best 5 will be published, while the others will be anonymous.
