carbon captured and stored long-term by marine and coastal vegetated ecosystems and their underlying sediments. 
It relies on tracking and conserving: 

• seagrass meadows and rhodolith beds; 

• mangrove forests and coastal salt marshes; 

• coral ecosystems and deep-sea environments. 
  

These habitats act as essential natural carbon sinks, helping mitigate global warming through the durable long-term storage of greenhouse gases.
