Scores cluster high, so position within the catalogue is often more telling than the number alone.

Evaluation

Evaluated by C-NAPSE

Score profile — the dimensions behind the score — how it's computed

Carbon — sequestration / storage, evidenced2/3

Plan Vivo validates 1,300+ tCO₂e/year of avoided mangrove deforestation; the modest annual figure reflects the 1,200 ha project area under a conservative deforestation baseline, not a methodology weakness.

Biodiversity — conservation / improvement, evidenced3/3

CCB Gold certification independently verifies mangrove habitat conservation for marine biodiversity; Blue Ventures field monitoring documents fish nursery function and recovery of mangrove-dependent species.

Water & soil — retention, infiltration, erosion control2/3

Mangroves demonstrably reduce coastal erosion and maintain nearshore sediment quality; the Commonwealth and Blue Ventures case studies cite storm-surge buffering as a documented co-benefit.

Fire resilience — risk reduction, evidenced0/3

Coastal mangrove wetlands are not susceptible to fire; this dimension does not apply to blue carbon projects.

Governance, certification & transferability3/3

Plan Vivo and CCB Gold certification, community-led governance through the Velondriake LMMA (a locally managed MPA), and 73% revenue retention by local actors demonstrate exemplary accountability and transferability.
