Guidance for national blue carbon activities
Coastal ecosystems – in particular mangroves, tidal marshes and seagrasses – are globally important natural carbon sinks with rich carbon reservoirs. However, when these ecosystems are converted or degraded, they release this stored carbon into the atmosphere and oceans and become sources of greenhouse gas (GHG) emissions. The conservation, restoration and sustainable use of these systems can support climate change mitigation, as well as conserve many other benefits these ecosystems provide, such as fisheries support and coastal protection important for climate adaptation.
