COP30 in Belém and Congo Basin Forests: What Changed for Carbon Markets

COP30 in Belém, at the heart of the Brazilian Amazon, was not merely symbolic. The Brazilian host intentionally structured a climate conference around the forest question — and the Congo Basin, the planet's second green lung, held a central place. Commitments made in Belém have direct and immediate implications for carbon project developers and investors operating in Cameroon's forests.

The Belém Call for Forests

The most structuring commitment to emerge from Belém is the Belém Call for Tropical Forests — a political declaration signed by over 80 countries committing to end tropical forest deforestation and degradation by 2030. Unlike the 2021 Glasgow pledge, the Belém Call is accompanied by concrete financing mechanisms, including a collective commitment of $20 billion in additional funding for tropical forest countries over 2025–2030.

For Cameroon, as a signatory to the Call, this commitment was accompanied by bilateral announcements. France formalized the Z3D programme (Zero Deforestation and Degradation for Development) with the DRC, with an architecture that foresees possible extension to other Congo Basin countries including Cameroon. Germany, through KfW, announced a doubling of its CAFI (Central African Forest Initiative) commitments for 2025–2030. These public funds create a conservation financing architecture that reduces sovereign risk for private carbon projects in the region.

Key Article 6 Decisions

Belém also produced significant advances on Article 6, the Paris Agreement's market mechanism. Several technical decisions were adopted by the Article 6.4 Supervisory Body:

The methodology for grid-connected renewable electricity was adopted, allowing solar and wind projects in Central Africa to generate PACM credits under Article 6.4 — an additional pathway that complements forest projects in Cameroon's carbon asset portfolio.

Rules on corresponding adjustments (CAs) were clarified, reducing the uncertainty that weighed on bilateral Article 6.2 transactions such as the Cameroon-Switzerland agreement. Developers operating under this agreement now have greater regulatory clarity to structure their credit pipelines.

The CAFI and Multilateral Funder Signal

One of the least visible but most structuring outcomes of Belém is the reinforcement of CAFI's mandate. The initiative, funded by Norway, the European Union, the United Kingdom, and Germany, manages large-scale conservation funds in Cameroon, DRC, Republic of Congo, and Central African Republic. At Belém, donors formalized an additional $1.5 billion commitment for 2025–2030, with a significant portion directed toward REDD+ results-based financing programs — direct payments to governments for measured deforestation reductions.

For private project developers, this injection of public capital has a dual effect: it strengthens national forest governance institutions (MINEPDED, national carbon registry) and it signals to private institutional buyers that sovereign risk in Cameroon is covered by a multilateral safety net, reducing the risk premium demanded on Cameroonian credits.

Evolving Buyer Expectations

Belém also accelerated adoption of the TNFD (Taskforce on Nature-related Financial Disclosures) framework by major global financial institutions. Several banks and asset managers who made TNFD commitments at Belém announced they would integrate biodiversity — not just carbon — into their credit purchasing criteria from 2027. For Cameroonian projects combining VCS and CCB certification (which explicitly integrates biodiversity), this shift in purchasing criteria is a direct opportunity: their credits will qualify to satisfy TNFD obligations of major institutions, where VCS-only credits will not.

Practical Impact on the Cameroon Pipeline

For project developers and investors operating in Cameroon, Belém's outcomes translate to five practical implications. First, additional public funding reduces political risk over the next decade: it is hard to imagine a forest policy reversal in a country benefiting from $1.5 billion in CAFI commitments and a bilateral Z3D programme with France. Second, clarified Article 6 rules accelerate the timeline for Cameroon's first ITMO transactions. Third, the growth of TNFD buyers creates an additional premium for VCS+CCB credits. Fourth, commitments from funders like KfW and AFD can co-finance the social components of projects, reducing costs for private developers. Fifth, the political signal from Belém strengthens the narrative legitimacy of Cameroonian credits with the boards and CSR committees of major corporate buyers — an underestimated but real factor in institutional purchasing decisions.
