A large-scale mangrove restoration project in Senegal failed to meet its reforestation goals, with over 36% of plots showing zero survival.
Inaccurate carbon storage calculations overestimated sequestration, potentially misrepresenting 168,000 tonnes of CO2 as 'offset' emissions.
The project faced criticism for failing to adequately compensate local communities and for using land unsuitable for mangrove growth.
Experts warn that without better ecological monitoring, such initiatives risk selling 'ghost carbon' credits that do not deliver real climate benefits.
