The participation of representatives of the Spanish Olympic Committee (COE), headed by its president, Mr. Alejandro Blanco, completes a working group that also includes in a stable manner the members of the Higher Sports Council (CSD) and the Secretariat of Sport of Portugal, among other organizations and institutions. The presence of the COE is particularly important in terms of the sustainability of the project. The COE, which presented a Manifesto for Sustainability in September 2022, is the most advanced national Olympic Committee worldwide in the concern and development of sustainability issues.
