Blue carbon projects risk dispossessing coastal communities without strong tenure rights protections

A new policy brief in Nature Climate Change warns that blue carbon projects, which aim to store carbon in mangroves, seagrasses, and tidal marshes, often overlook the land and sea rights of Indigenous peoples and coastal communities. The authors reviewed 122 guidance documents and found that most treat tenure rights as a condition for project approval rather than a legal and ethical duty. This approach risks repeating patterns of dispossession, as projects are often foreign-led and require long-term permanence, limiting local control over resources. The study recommends that blue carbon policy must adopt global instruments like the Voluntary Guidelines on Tenure and ILO Convention 169 as binding obligations. It also calls for rightsholders to lead projects, not just participate in them. Without these safeguards, the push for carbon credits from coastal ecosystems could undermine the very communities that steward these environments.

This is a solid reality check. Blue carbon credits sound great on paper but if the local community doesn't have real control, you are just creating another carbon offset with a social cost.

Exactly. The paper points out that most guidance treats rights as a checkbox for investors, not as something communities actually hold. That is a fundamental flaw in how these markets are being built.

The key finding for me is that international obligations like the Voluntary Guidelines on Tenure are just absent from most blue carbon guidance. That is not an oversight, it is a choice about who the market serves.

Makes you wonder how many of these projects will actually deliver carbon storage over 100 years if the people on the ground are not fully on board. Permanence is hard enough without tenure disputes.

Worth noting this is from Nature Climate Change, not some activist blog. The fact that a major scientific journal is publishing this signals a shift in how the blue carbon space is being scrutinized.
