Blue Carbon &
Marine Ecosystems
Blue carbon ecosystems sequester carbon at rates up to 10× faster per hectare than terrestrial forests, storing it in sediments for thousands of years. From mangrove restoration in West Africa to seagrass protection in the Indo-Pacific, Teravent supports the full breadth of coastal and marine carbon removal.

Blue carbon ecosystems - mangroves, seagrasses, saltmarshes and tidal wetlands - are among the most carbon-dense ecosystems on Earth. They sequester carbon in both their biomass and, critically, in anoxic sediments below the waterline where decomposition is extremely slow. Carbon stored in these sediments can remain locked away for millennia.
Teravent supports both conservation-based projects (preventing loss of existing ecosystems) and restoration-based projects (re-establishing ecosystems on degraded coastal land). Methodologies align with the IPCC Wetlands Supplement and Teravent MRP-04 for water chemistry monitoring in marine environments.
The Global South - particularly the coastlines of Sub-Saharan Africa, South and Southeast Asia, and Latin America - contains the majority of the world's remaining intact mangrove and seagrass resources, and is the primary focus of Teravent's blue carbon programme.
Project types accepted
The following variants of the Blue Carbon pathway are currently eligible for registration in the Teravent Registry.
Measurement, reporting
& verification
Teravent's Science Advisory Board assesses each pathway against four MRV dimensions. These scores reflect the current state of measurement science and are updated as methodology evolves.
Blue carbon MRV requires integration of remote sensing (Sentinel-2, LiDAR), ground-truth plot sampling, and sediment core analysis for soil organic carbon. Teravent MRP-04 governs water chemistry monitoring for coastal and marine projects.
Key registration criteria
Projects must meet all of the following minimum requirements to be considered for registration under the Blue Carbon pathway. Additional requirements may apply depending on project size, geography, and specific methodology version.
Sustainable Development
Goal alignment
All Teravent registered Blue Carbon projects must complete an SDG impact assessment at registration and at each verification period. 7 SDGs are tracked for this pathway.
Focus region: West Africa, SE Asia, Latin America - where co-benefits for communities and ecosystems are most significant and credit demand most transformational.
