Blue Flag is a global eco-label awarded to beaches engaged in sustainable tourism: sustainable site management, bathing water quality and user awareness. Created by the Foundation for Environmental Education (FEE), the label is present in 45 countries and has been awarded to 4423 beaches or marinas.

Blue Flag, created in 1987, is now a major label on all five continents. Flying the blue flag for a beach is the expression of genuine and deep commitment to coastal environment, water quality, safety and free access for all.

The Blue Flag Program's philosophy is to connect the public to the environment and encourage people to learn more. As such, beaches offer environmental education activities and provide relevant site information on biodiversity, ecosystems and environmental phenomena on an ongoing basis.

Beaches apply for the blue flag label each year well before the summer season. A multi-disciplinary jury awards the label in the spring, and conducts inspections during the summer to ensure that all criteria are met by labelled beaches.

The Foundation introduced the label in 2006 for beaches and in 2016 for marinas. Over twenty beaches are labelled each year, and the first blue flag for a marina was awarded in 2017.
