Oceans are both the greatest victims of climate change and its greatest mitigators. This policy brief urges the G20 to strengthen the role of blue carbon (BC), nature-based solutions (NbS) and ecosystem-based adaptation (EbA) at international forums and initiate funding mechanisms for their implementation. The G20 can further ocean science by including BC targets at the United Nations Framework Convention on Climate Change and Convention on Biological Diversity, encourage countries to include these in Nationally-Determined Contributions and biodiversity targets, manage Marine Protected Areas through common international mechanisms, implement NbS to protect coastal ecosystems from pollution and enhance climate adaptation through EbA.
