Navigating Nature Based Solutions – The 2026 Forecast

The voluntary carbon market (VCM) has passed its inflection point. The volatility that characterized 2023 and 2024 has settled into a stark, data-driven reality: the market has bifurcated. As we look toward 2026, corporate leaders face two distinct markets. One is a liquid, low-price market of legacy credits facing increasing obsolescence. The other is a constrained, high-value market of high-quality assets. Specifically within Nature-Based Solutions (NBS), where demand is beginning to structurally outstrip supply.

For the capital-intensive, risk-averse organization, the strategy for 2026 cannot rely on the spot market procurement tactics of the past decade. The data from 2025 indicates that securing access to high-quality NBS is no longer just a corporate social responsibility objective; it is a balance sheet imperative driven by regulatory convergence and the tangible risk of stranded assets.

The End of Uniformity: The Quality Premium Widens

The most critical signal for your 2026 strategy is the decoupling of credit prices based on integrity.

In 2025, while total credit retirements marginally declined by 4.5% to 168 million tonnes, the primary market value actually grew by over 6% to $1.04 billion. This counter-intuitive dynamic—lower volume, higher value—proves that buyers are actively discarding low-quality inventory in favor of fewer, higher-quality assets.

This “flight to quality” has created a substantial price premium. In previous years, the spread between high and low-rated credits was negligible. By mid-2025, MSCI reported that credits rated ‘BBB’ and above were trading at a premium of approximately 360% over lower-rated credits. Specifically within NBS, Afforestation, Reforestation, and Revegetation (ARR) projects rated ‘BBB+’ averaged $26.10 per tonne, while their lower-rated counterparts (‘BB-‘ and below) languished at $14.50.

For the CFO, this presents a clear heuristic: the “cheap” option carries a hidden cost. Low-quality credits now face a high probability of becoming stranded assets. Credits that are technically issued but unusable for credible net-zero claims or compliance obligations due to reputational toxicity or regulatory exclusion.

The Supply Crunch in High-Quality NBS

As your organization forecasts its procurement needs for 2026, you must account for a deepening supply deficit in the specific assets you likely desire. While the overall market holds a surplus of legacy credits, the inventory of high-quality credits is shrinking.

For the third consecutive year, highly-rated credits (BBB+) experienced a market deficit in 2025, meaning retirements (consumption) exceeded new issuances. This scarcity is acute in Nature-Based Solutions. While forestry and land use, accounting for 68 million tonnes in 2024, remain the most frequently retired project category, the composition of that supply is changing.

Buyers are aggressively shifting away from legacy REDD+ (avoided deforestation) projects toward removal-based NBS, such as ARR and Improved Forest Management (IFM). In 2025, transaction volumes for IFM projects grew over 300%, while legacy REDD+ volumes fell by 52%.

The implication for your 2026 planning is scarcity. The lead time for new high-quality NBS projects to come online is significant. Consequently, we are witnessing a surge in early-stage offtake agreements. In 2025, the value of announced offtake deals totaled $12.25 billion… a massive leap from $3.95 billion in 2024. Sophisticated buyers, including major energy and technology firms, are locking in future supply at weighted average prices of $160 per credit for durable removals, effectively bypassing the spot market entirely.

Regulatory Convergence: The Compliance Floor

The distinction between “voluntary” and “compliance” markets is eroding, and this convergence will be a primary price driver in 2026. Regulatory bodies are increasingly creating a floor for credit quality that impacts voluntary buyers.

Two mechanisms are driving this shift:

1. CORSIA Phase 1

The Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA) has entered its first mandatory compliance phase (2024–2026). The International Civil Aviation Organization (ICAO) has tightened eligibility, creating a “compliance-grade” stamp of approval. Sylvera modeling suggests that compliance demand could exceed voluntary demand as early as 2027, largely driven by the approaching CORSIA Phase 1 deadline. This will create direct competition for high-integrity credits between voluntary corporate buyers and regulated aviation entities, inevitably driving up price floors for eligible NBS credits.

2. Article 6 and Corresponding Adjustments

The operationalization of Article 6 of the Paris Agreement is accelerating. As of late 2025, 176 bilateral agreements were in place under Article 6.2. This mechanism allows countries to transfer carbon credits (Internationally Transferred Mitigation Outcomes, or ITMOs) to one another.

For corporate buyers, the critical development for 2026 is the “Corresponding Adjustment” (CA). A CA ensures that when a credit is sold abroad, the host country deducts it from its own national inventory, preventing double-counting. We project that credits with a CA will command a distinct premium and may become a requirement for companies making specific claims under the Paris Agreement framework. With countries like Singapore and Japan already executing trades, the infrastructure for this high-compliance market is solidifying.

3. The Role of Independent Assurance

In an environment of rising prices and regulatory complexity, “trust” is a risk management tool. Reliance on project developer marketing materials is insufficient for audit committees and risk officers.

The rise of independent rating agencies such as MSCI, Sylvera, Calyx Global, and BeZero, has fundamentally altered the due diligence landscape. These agencies now cover the majority of the market; Calyx Global’s ratings alone cover 70% of all retirements from 2021 to 2024.

Data indicates that utilizing these ratings is becoming a prerequisite for transaction security. Buyers are increasingly writing clauses into offtake agreements that allow them to exit the contract if a project’s third-party rating drops below a certain threshold (e.g., ‘BBB’). For 2026, we advise integrating independent ratings data directly into your procurement workflows to mitigate delivery and reputational risk.

Strategic Outlook for 2026

Based on the current trajectory, the role of Nature-Based Solutions in 2026 will be defined by three core realities:

1. NBS as a Removal Mechanism: The market will continue to prize “removals” (sequestering carbon) over “avoidance” (preventing emissions). In 2024, removal credits commanded a 381% price premium over reduction credits, up from 245% the previous year. Corporations with net-zero targets must prioritize ARR and IFM projects to align with the Science Based Targets initiative (SBTi) guidance on residual emissions.
2. Co-Benefits as Value Drivers: Buyers are no longer paying solely for the carbon molecule. They are paying for the verified impact on biodiversity and local communities. Projects with quantifiable co-benefits are achieving measurable price uplifts. In 2026, expect biodiversity monitoring to become a standard component of high-quality NBS due diligence.
3. The Necessity of Long-Term Positions: The spot market for high-integrity NBS is thinning. If your organization waits to purchase 2026 vintage credits in 2026, you will likely face a restricted supply of “leftover” inventory at inflated prices. The $12 billion surge in offtakes signals that your peers are moving upstream to finance project development directly.

Recommendations for the C-Suite

To navigate the 2026 carbon market landscape effectively, we recommend the following actions:

• Audit Your Inventory: Assess your current holdings against independent ratings. Identify assets at risk of becoming “stranded” due to low integrity scores or lack of alignment with Core Carbon Principles (CCPs).
• Pivot to Offtakes: Move from spot purchasing to multi-year offtake agreements for high-quality ARR and IFM projects. This hedges against future price spikes and secures supply.
• Integrate Compliance Standards: Even if your purchasing is voluntary, align your quality thresholds with CORSIA Phase 1 or Article 6 requirements to future-proof your investments against regulatory creep.
• Demand Data: Require independent ratings and granular monitoring data (MRV) for all prospective NBS investments. Do not rely on issuer claims alone.

The era of cheap, opaque carbon credits is effectively over. The market of 2026 offers clarity and impact, but only for those willing to invest in integrity.
