Cuvette Centrale: the Congo Basin peatland storing 30 billion tonnes of carbon

The Cuvette Centrale in the Congo Basin is the largest tropical peatland complex in the world. Recent mapping puts it at around 167,600 sq km, larger than New York State. Researchers estimate it stores roughly 30 billion tonnes of carbon, equal to about three years of global fossil fuel emissions and nearly 30 percent of tropical peatland carbon worldwide. Most of that carbon stays locked underground because the peat is waterlogged. Drainage, deforestation, logging, oil and gas exploration, and infrastructure could expose the peat to oxygen and speed up decomposition. The Republic of Congo and DRC have set up a transboundary Ramsar site and signed the Brazzaville Declaration, but enforcement and land use rules remain the open question.

30 billion tonnes of carbon in one peatland is a big number. The piece notes drainage or deforestation could release it, but doesn't get into who controls the land or what incentives exist to keep it wet. That is the part that matters for carbon finance.

The Brazzaville Declaration and Ramsar site are the policy hook here. Transboundary protection only works if both DRC and Republic of Congo have enforcement capacity and funding. The article mentions the agreement but not whether either country has actually changed land use rules since 2018. That is the missing detail.

Peat saturation is the real issue. If the hydrology stays intact, the carbon stays put. The piece lists logging and oil exploration as threats, but roads and drainage from infrastructure projects are often what actually dry out peat. Would like to see a map of where the pressures overlap with the 167,600 sq km boundary.

Good explainer on why the Cuvette Centrale matters. The comparison to New York State helps, and the 30 billion tonne figure is concrete. For anyone tracking carbon markets, the question is whether these peatlands can generate verified credits that fund protection without opening the door to drainage projects elsewhere.
