dans ce catalogue (918 pratiques notées)
Les scores se concentrent dans le haut de l’échelle ; la position au sein du catalogue est donc souvent plus parlante que le chiffre seul.
Carbon — sequestration / storage, evidenced1/3
A carbon-credit scheme sold ~500,000 credits, but peer-reviewed satellite analysis found 96% of regrowth was natural rather than planted, undermining the credited carbon claim.
Biodiversity — conservation / improvement, evidenced1/3
Mangrove cover statistics are reported, but no dedicated biodiversity outcome monitoring (e.g., fish nurseries, bird counts) is documented in available sources.
Water & soil — retention, infiltration, erosion control1/3
Mangrove restoration plausibly aids coastal soil stabilisation, but no site-specific erosion or sediment data is reported, and many planted sites failed to establish.
Fire resilience — risk reduction, evidenced0/3
Not applicable to a mangrove/coastal programme; no data reported.
Governance, certification & transferability0/3
Independent investigation found roughly a third of sold credits were unsupported, monitoring assumed 100% tree survival despite ~18-20% measured survival, and only 5.2% of spending reached local communities — a documented governance and verification failure.
