The value in Tanzania's coastal carbon, brought to market.

We originate, certify and sell high-integrity coastal carbon from Tanzania's mangroves, in partnership with the villages that co-manage them.

For buyers & investors How the model works

Most mangrove carbon is in the mud, not the trees.

Tidal flooding starves mangrove soils of oxygen, so leaf litter and roots decompose slowly and the carbon builds up underground over centuries. That is what makes a well-governed mangrove forest a durable carbon asset, and why losing one releases far more than its trees suggest.

In a study of 25 Indo-Pacific mangrove forests, soils held 49-98% of ecosystem carbon. Donato et al., 2011, Nature Geoscience

Our coastal portfolio

We originate credits, coordinate certification and MRV, structure offtake agreements with buyers, and build a pipeline of coastal assets along Tanzania's coast.
