Sierra Leone mangrove communities secure carbon deal with real revenue share

Hundreds of communities in Sierra Leone's Bonthe district just signed something rare in the carbon offset world: an agreement where they actually keep most of the money.

The deal, brokered with the Africa Conservation Initiative, protects roughly 79,000 hectares of mangroves in the Sherbro River Estuary—about half of Sierra Leone's remaining mangrove forests. But what makes it different is how the money flows. Communities get 40–50% of gross carbon revenue. They had a say in the process. They'll manage the forests themselves. And they can see the books.

This matters because carbon projects have a reputation. For decades, they've worked like this: a company plants trees or protects forests in a poor country, sells carbon credits to a rich company wanting to offset emissions, and the local people get crumbs. Sometimes nothing. This agreement flips that.

Why mangroves, why now

Mangroves are being cut down fast. Communities need wood for cooking fires, smoking fish, farming, building. The forest shrinks. The carbon stays in the atmosphere. So instead of just saying "stop cutting," ACI is offering alternatives: efficient cookstoves that use less wood, fish-smoking ovens, timber woodlots on cleared land, and access to money to invest in other things.

When those alternatives work and mangroves recover, independent auditors measure the carbon saved. ACI gets credits to sell. But here's the teeth: ACI won't sell to companies that aren't cutting their own emissions. No pure offset laundering.

Sandy Rogers, a youth leader in Sittia Chiefdom, sees it plainly: "employment and development." The revenue could mean schools, clinics, roads. But that's only if the money actually reaches communities and they spend it on what matters to them—not what outsiders think they should want.

Experts call the financial transparency clause a breakthrough. Carbon Market Watch's Isa Mulder said the agreement "is a step in the right direction for the voluntary carbon market to address the many deep-rooted issues of fairness and even human rights violations." That's careful language for "this usually goes wrong." This time, the structure makes it harder to.

The real test comes now. Implementation is messy. Communities need to see the money flow on schedule. They need to trust ACI and each other to manage it well. But for the first time, they're not starting from zero power. They signed an agreement that assumes they deserve a fair deal—and built in the mechanisms to prove it.
