Ocean-based solutions refer to the opportunities offered by – and related to – the global ocean to address the causes of global climate change either by reducing anthropogenic greenhouse gas emissions or by increas[ing] their long-term removal from the atmosphere and adapt to its impacts. It includes areas of focus such as protecting and/or restoring coastal blue carbon ecosystems, deploying marine renewable energy, enhancing sustainable and climate-ready aquatic food systems, developing sustainable coastal tourism, and greening the shipping sector. While coastal and marine NbS aim to achieve biodiversity conservation and socio-economic benefits, the sole objective of ocean-based solutions is climate mitigation and adaptation.
