The Ocean & Climate Platform (OCP) is an international network bringing together more than 100 organisations from civil society (non-governmental organisations, research institutes, foundations, local authorities, international organisations and private sector entities). Created in the run-up to COP21 in Paris, the OCP aims to promote scientific expertise on the major role played by the ocean and its ecosystems in the climate system, and to advocate for better consideration of these interactions by national and international decision-makers. Building on the wide-ranging expertise of its members, the OCP brings light to concrete solutions to protect the ocean, biodiversity and the climate.
