The Blue Flag Marina programme applies the same rigorous annual certification process used for beaches — but tailored to the specific needs of recreational boating facilities. A marina must satisfy criteria across water quality monitoring, environmental management, safety services, and environmental education to earn and retain its flag each season.
Spain leads globally with 10 certified marinas, followed by Brazil and Croatia with 7 each. The programme is strongest in Europe, where integrated coastal management policies have driven steady uptake, but South American marinas — particularly in Brazil and Chile — have grown significantly in recent cycles.
Marina certification criteria differ meaningfully from beach criteria: wastewater handling, fuel spill response protocols, and facilities for vessel maintenance waste are all assessed alongside the water quality and safety measures familiar from beach awards.
