Oceans Day at COP 21 in Paris was a landmark event that helped push the ocean and climate agenda to its inclusion as one of the eight priorities to be fast-tracked under the Marrakech Partnership for Global Climate Action. COP 22 saw a strong presence of the ocean community representatives who continued building the momentum and raising awareness on the relevance of ocean-related issues in the climate change realm, including through Oceans Action Day at COP 22. The COP 23 Oceans Action Day focused on action on the ground and showcased lessons learned, best practices and recommendations for replication and upscaling of successful experiences going forward as the Paris Agreement is further implemented.
