International policy framework for blue carbon ecosystems

Coastal blue carbon ecosystems, including mangroves, seagrasses and tidal marshes, are some of the most carbon-rich ecosystems on Earth, and are vital to mitigating the impacts of climate change. They are also critical for coastal biodiversity, food security, livelihoods and human well-being, in addition to climate adaptation – protecting millions of people globally from the impacts of storms, coastal flooding and erosion. However, these ecosystems are threatened – half of global mangrove forests have already been lost – and once these ecosystems are degraded or destroyed, their carbon stores are released as carbon dioxide, contributing to climate change. This policy framework, developed by Conservation International and IUCN, provides an overview of the intersections and opportunities for blue carbon ecosystem conservation and restoration in the relevant international policy processes.
