The Register of Bathing Water Identities, established by the former Special Secretariat for Water, now the General Secretariat for the Natural Environment and Water, assigns the official characterisation of bathing waters at national level. The Register, the results of the Bathing Water Quality Monitoring Programme and the assessment of bathing water quality by the General Secretariat for the Environment and Water are published annually and sent to the European Union as the official position of Greece.
The Blue Flag Programme is an initiative of the international organisation Foundation for Environmental Education, represented in Greece by the Hellenic Society for the Protection of Nature. The Hellenic Society for the Protection of Nature collaborates with the Ministry of Environment and Energy and in particular, makes use of the official published results of the Monitoring Programme for the quality of the country's bathing waters for the participation of stakeholders in the international voluntary programme "Blue Flag" ("BLUE FLAG"). In the year 2023, 617 Greek beaches, 18 marinas and 6 tourist boats were awarded with the Blue Flag.
