Microsoft’s 1.8 million carbon credits from Africa’s rainforests is not just a catchy headline: it is a concrete signal of how major buyers are seeking “future” CO₂ removals through long-term contracts, rather than buying spot credits at the last minute. The deal involves a multi-year offtake in Sierra Leone and fits a broader trend in the voluntary carbon market toward rewarding credits backed by more robust methodologies and clearer traceability.
Where the 1.8 million credits come from: project, countries involved, and type (REDD+, reforestation, or conservation)
The agreement is a 15-year offtake for up to 1.8 million carbon removal credits from a single project in Sierra Leone (West Africa), described as one of the largest African removal transactions from a single project.

The thing most
From a methodological standpoint, for ARR projects the cited reference is Verra VCS VM0047 (updated version v1.1). In many cases, when a buyer also wants evidence on biodiversity and social impacts, a framework such as CCB (Climate, Community & Biodiversity) is added to document co-benefits. Source: Verra VM0047.
If you look at it as a procurement “spec sheet,” the key fields are:
- Volume: up to 1.8 million (delivered over time, not all at once)
- Term: 15 years (forward delivery)
- Category: carbon removals (nature-based ARR)
- Geography: Sierra Leone
- Asset: restoration/re-establishment of lowland rainforest, as reported in sector descriptions
- Structure: offtake (useful for making the project financeable and bankable, compared with spot sales) Source: Carbon Pulse.
Box: Africa is not a monolith (and Microsoft thinks in “portfolio” terms)
Microsoft has also signed other agreements in Africa for removal credits from afforestation/reforestation—for example in Uganda, via a deal reported by Data Center Dynamics (with supply intermediated by Rubicon). This helps interpret the strategy as a portfolio across multiple countries and projects, rather than a bet on a single context. (Uganda is an East African country, distinct from Sierra Leone’s West African context.) Source: Data Center Dynamics.
Why Microsoft is buying them: climate targets, offset strategy, and credit selection criteria
The main lever is security of future supply of removals. A long offtake reduces the risk of finding, a few years from now, that there are too few “good” credits available—or that prices are highly volatile. In addition, contracts like these can act as a financial enabler for the project, because they make revenues more predictable. Source: Carbon Pulse.
On the “why these credits specifically,” the typical checklist that emerges for large buyers includes:
- Growing preference for removals (instead of avoidance) to reduce disputes over claims and perceived integrity
- Robust methodology for ARR, such as VM0047, with rules on quantification, monitoring, and uncertainty management
- Stricter MRV and an expectation of access to verifiable evidence (documents, data, audit trail) Source: Verra VM0047.
This also fits the hierarchy of “reduce first, then neutralize residuals”: many companies are shifting attention and budget toward CDR (carbon dioxide removal), including deals for nature-based removals and also other removal pathways (for example, biochar removal deals have been communicated in the Microsoft ecosystem).

For a B2B company, the practical message is clear: big buyers often ask for multi-year terms, forward delivery, deep due diligence, and contractual conditions covering:
- access to MRV data and audits
- management of reversals (loss of stored carbon)
- buffers and “make-good” obligations Principle references on integrity and expectations: Verra VM0047.
Three “real” questions a buyer asks—and all of them apply here:
- What kind of claim can I make (net-zero, carbon neutral, contribution)?
- How does accounting differ between removals and avoidance?
- How do I assess country risk and a potential “sovereign risk discount,” and why can a very large buyer absorb it more easily? Source: VCM.fyi.
What risks to assess in credits linked to African rainforests: additionality, permanence, leakage, and baseline
Integrity is not an abstract concept. In forest credits, even when they are removals, technical and social risks can affect both quality and delivery over time.
Additionality means the project must demonstrate that removals would not have happened “anyway.” In ARR this often relies on evidence of financial/technical barriers, alternative land uses, and “common practice.” Serious buyers ask for documentation and verifiable reasoning, because it is one of the most attacked points in debates about forest credits. Integrity principles reference: ICVCM Core Carbon Principles.
Permanence is the risk that stored carbon returns to the atmosphere. In rainforests and tropical contexts, drivers can include fires, climate stress, pests, illegal logging, and instability. That is why buffer pools, management plans, contingencies, and contractual replacement clauses come into play. Principles reference: ICVCM CCP.
Leakage does not disappear just because we are talking about reforestation. It can be physical (pressures shifting elsewhere) or economic (market and land-use changes). Due diligence should examine how the methodology treats leakage and what evidence is monitored and verified. Methodological reference: Verra VM0047.
Baseline: one of the classic problems with “avoidance/REDD+” credits is the counterfactual baseline (what would have happened without the project), which is often contested. In ARR projects the baseline is different (growth and carbon stocks), but it remains sensitive to assumptions and data: historical land use, remote sensing, biomass growth models, uncertainties. Reference: Verra VM0047.
Finally, there is reputational risk: forest credits are under scrutiny and market skepticism is real. The best defense is a clear policy, cautious disclosure, and selection of standards and methodologies with stronger requirements. Reference: ICVCM CCP.
How to verify credit quality: standards, audits, registries, and data transparency (MRV)
Verification starts with the standard and goes all the way down to the data. If you are assessing credits similar to those in the Microsoft 1.8 million carbon credits Africa rainforests deal, this is the sequence that typically stands up best to due diligence.
Standard and methodology: for ARR, the operational reference is Verra VCS with VM0047. The methodology defines how to quantify removals from afforestation/reforestation/greening, how to treat leakage and uncertainties, and what to monitor over time. Source: Verra VM0047.
Audit and assurance: in the VCM the typical flow includes initial validation and periodic verification by accredited third parties. A buyer should request the latest reports, including any non-conformities and corrective action requests (CARs). Integrity principles reference: ICVCM CCP.
Registries: traceability runs through a registry with serialization, issuance, transfer, and retirement. The minimum check is to verify that credits are retired in the buyer’s name and that there is no double counting. Reference: ICVCM CCP.
MRV and data transparency: on the enterprise side, the ask is not “trust us.” It is access to:
- project boundaries and maps
- geospatial datasets and satellite monitoring
- forest inventories and QA/QC procedures
- operational indicators (e.g., survival rate, uncertainty, leakage belt) Reference: ICVCM CCP.
Integrity labels/benchmarks: ICVCM’s Core Carbon Principles (CCP) can be used as an initial filter for procurement and risk committees. They do not replace due diligence, but they help structure requirements and comparisons across credits. Source: ICVCM CCP.
Local impacts and biodiversity: what changes for communities, governance, and forest protection
Co-benefits are not “decorations.” In a forest project they can become operational conditions to avoid conflict and ensure credit delivery over time.
Many forest projects combine VCS with CCB to provide structure around biodiversity, communities, and governance. This is often required by ESG policies and nature-positive strategies, especially when rainforests are involved. Source: Rainforest Builder.
The most sensitive point is benefit sharing and inclusion. In practice this means clear mechanisms for distributing benefits, local employment, models such as agroforestry, land-rights management, and consultation processes (often referred to as FPIC). If these elements fail, the risk is not only ethical: it can become a material project risk (delays, disputes, suspensions). An institutional example on community access to funds from carbon credits is reported by the World Bank. Source: World Bank.
Governance is assessed with simple but tough questions:
- who holds the carbon rights?
- how does the grievance mechanism work?
- what role do local and national authorities play?
- how is country risk managed and how transparent is it toward buyers and stakeholders? Link to the “sovereign risk discount” topic: VCM.fyi.
On biodiversity, the real difference is between planting “cover” and delivering ecological restoration. Useful KPIs for a buyer: native species, habitat connectivity, protection of high conservation value (HCV) areas, fauna and flora indicators, and a readable management plan. Source: Rainforest Builder.
Finally, local economic impacts should also be read as operational risk: nurseries, services, MRV, and skills can build local value chains, but attention is needed on displacement (access to land, grazing, harvesting). A checklist aligned with integrity and safeguarding principles can be integrated into the supplier code of conduct. Source: ICVCM CCP.
What to expect for prices and demand in the voluntary market after deals of this scale (and how companies position themselves)
An offtake of up to 1.8 million over 15 years is, above all, a signal of “serious” demand for future removals. It reinforces the idea that high-integrity credits may be scarce and that large buyers prefer to lock in volumes early, rather than competing on the spot market. Source: Carbon Pulse.
On pricing—without making up numbers—the direction is:
- ARR removal credits tend to behave differently from avoidance and “legacy” credits
- you can expect greater price dispersion and a premium for robust MRV, verified co-benefits, and lower risk
- benchmarks such as the CCP can widen the “quality spread,” because they make minimum requirements and exclusions more explicit Source: ICVCM CCP.
For companies, the implication is a rebalancing of the mix: more focus on rigorous methodologies and credits with higher perceived integrity, and more conservative, well-documented claims. Source: ICVCM CCP.
How to position yourself, in practice:
- Portfolio approach: a mix of nature-based removals and other removal types, to diversify permanence and delivery risks.
- Offtake vs spot: use forward contracts when you need volume certainty and when you want to support project financeability.
- Intermediaries and structuring: some deals are facilitated by players that aggregate supply and structure contracts, as shown by the Uganda agreement reported by Data Center Dynamics. Source: Data Center Dynamics.
- Internal governance: bring risk, legal, and finance in early, because reversal, MRV data, and replacement clauses have real impacts.
Typical CFO and CSO questions quickly get practical: budget and spend profile, reversal risk management, alignment with net-zero targets, and the ability to produce evidence (MRV datasets and proof of registry retirement). Useful immediate actions: a standardized RFP, an MRV data room, an audit trail, and CCP-inspired criteria. Source: ICVCM CCP.
