From a Portuguese pilot to a global federation.
The Blue Schools concept emerged from ocean literacy conversations at EMSEA conferences and the EU's Sea Change project in the mid-2010s. Portugal ran with it first. The rest followed.
The idea takes shape
Educators at EMSEA (European Marine Science Educators Association) conferences and within the Sea Change project identify a gap: environmental education doesn't adequately address ocean literacy as a long-term, structured school commitment.
Escola Azul launches in Portugal
The Directorate-General for Maritime Policy, working with the Ministry of the Sea and Ministry of Education, launches the world's first national Blue School programme. The structured, interdisciplinary approach becomes the reference model.
Europe goes blue
The European Commission establishes the Network of European Blue Schools under the EU4Ocean Coalition, funded through DG MARE. Certification opens to schools across all EU Member States.
Across the Atlantic
Brazil and Argentina launch pilot programmes, joining Portugal to form the All-Atlantic Blue Schools Network — framed within the All-Atlantic Ocean Research Alliance.
The USA joins
The National Marine Educators Association, with NOAA support, launches USA Blue Schools, bringing the model to American K-12 classrooms.
A global network
UNESCO's Intergovernmental Oceanographic Commission formally launches the Blue School Global Network as the worldwide umbrella, connecting approximately 60 countries under a shared framework.
