We take an in-depth look at the numbers to assess pricing in the VCM.
In the voluntary carbon market (VCM), pricing can often feel like a moving target. One month a forest conservation credit sells for $3, and the next, a seemingly similar credit commands $25.
A new study by financial economists from MIT Sloan, VU Amsterdam, and Goethe University Frankfurt takes an in-depth look at the numbers and provides long-overdue answers. Analyzing transaction-level data covering roughly 11% of global secondary VCM trade value between 2018 and 2024, the authors established a fundamental truth: the VCM does not function as a single, uniform commodity market. Instead, credits trade as highly differentiated goods. Prices reflect buyer demographics, brand goals, and non-carbon co-benefits far more than a standardized price per metric ton of CO2 abated.
Whether you are scaling nature-based solutions (NBS) or leading corporate sustainability procurement, this research offers crucial, actionable insights.
The study’s most striking finding is the persistent, massive price premium that nature-based projects command over traditional mitigation technologies.
Across dealer transactions, nature-based removal credits like afforestation and reforestation garner prices 235% to 362% higher than renewable energy credits. Nature-based avoidance credits, primarily forest protection under REDD+ frameworks, trade at a 99% to 146% premium over renewables. Household projects (like clean cookstoves) see similar gains (+103% to +159%), while industrial process and waste-management projects trade with virtually no premium.
What makes this price hierarchy so notable is that it exists alongside ongoing public debates regarding carbon delivery risk. External academic evaluations (like Probst et al., 2024) frequently give nature-based avoidance projects lower ratings for additionality and delivery-to-promise compared to industrial waste projects. Yet, buyers consistently are willing to pay far more for nature. Even after high-profile investigative reports in late 2023 raised public quality concerns about major REDD+ projects, the nature-based avoidance price premium remained virtually unchanged.
Companies are willing to pay a premium because they are rarely solely purchasing for just carbon abatement. They are buying brand positioning, employee engagement, and tangible ecological narratives. Nature-based solutions excel at delivering co-benefits, such as biodiversity conservation, watershed protection, and local economic development.
The paper shows:
Registry focus: Credits certified by Gold Standard, a registry whose methodologies explicitly emphasize social and environmental co-benefits, trade at a premium of up to 36% once host-country baseline factors are controlled for.
SDG contributions: Each additional United Nations Sustainable Development Goal (SDG) claim documented in project paperwork correlates with a 4% price increase in transaction data.
For corporate credit buyers, the study exposes a clear reality: what you pay depends heavily on who you are, how much you buy, and who is selling.
Because the VCM operates primarily over-the-counter (OTC) through dealers with limited pre-trade price transparency, intermediaries hold substantial pricing power. Within the exact same project and vintage year, simultaneous transaction prices can differ by a factor of two or more across different corporate buyers.
The study highlights key buyer-side dynamics:
Sector preferences: Financial institutions and consumer-sector firms pay 9% to 22% more for credits than industrial manufacturing buyers purchasing from the same project.
Volume leverage: Top-tier accounts (the 20 largest buyers in the dataset) secure price discounts of 16% to 23% relative to smaller corporate buyers, beyond standard transaction volume concessions.
Wealth & location: Buyers domiciled in wealthier countries (higher GDP per capita) regularly pay higher prices for identical credits.
The SBTi misconception: Surprisingly, firms with public commitments under the Science Based Targets initiative (SBTi) do not pay higher prices for credits. Because SBTi rules include restrictions on using carbon credits toward core net-zero reduction targets, these buyers approach offset purchases with standard commercial discipline.
For corporate procurement teams, especially smaller companies or non-industrial firms, these findings mean you may be paying an opacity tax simply due to dealer pricing structures and a lack of market price benchmarks.
The study also explains why attempts to commoditize the VCM through exchange-traded basket contracts (such as CME futures or Xpansiv CBL’s GEO products) largely failed.
Standardized basket contracts allowed sellers to fulfill delivery using any eligible credit. Driven by no-arbitrage logic, sellers delivered the cheapest-to-deliver eligible credits into the pool. Because corporate buyers actively care about specific project attributes and narratives, generic basket prices quickly plunged to the bottom of the price distribution, and trading volumes collapsed to near zero by 2024.
This failure offers a lesson for both sides: buyers do not want homogenized carbon tokens, and project developers cannot rely on generic spot exchanges to capture their project’s full financial value.
The study’s findings provide practical strategies for both sides of the market:
Rigorously quantify and certify co-benefits: Do not leave biodiversity or community benefits as secondary marketing points. Pursuing dual-certification or registering under co-benefit-focused standards directly unlocks higher prices.
Target the right off-takers: Consumer goods companies, financial service firms, and brand-sensitive multinationals consistently demonstrate a higher willingness to pay for nature narratives than heavy industrial firms.
Prioritize direct-to-buyer relationships: Standardized exchange pools are not where nature-based projects capture value. Tailored storytelling and direct off-take agreements yield far better price realizations than spot market commoditization.
Benchmarking is critical: Recognize that dealer quotes in OTC markets vary wildly. Compare quotes across multiple intermediaries and evaluate historical trade data to avoid paying unnecessary buyer-specific markups.
Distinguish carbon value from storytelling: Understand what you are paying for. If your goal is high co-benefit visibility, paying a nature premium makes sense. If your goal is strict emissions compensation, ensure the underlying carbon accounting, additionality, and delivery ratings match the price tag.
Leverage purchasing scale: Where possible, consolidate credit purchases into larger bulk transactions or multi-year off-take agreements to capture the significant volume discounts available in the market.
The voluntary carbon market is not a simple commodity floor; it is a complex marketplace shaped by buyer values and intermediary dynamics. For nature project developers, highlighting holistic ecological impact remains the primary driver of premium pricing. For corporate buyers, understanding market opacity is the key to smarter procurement.

💡 Finding a reputable and transparent carbon credit partner is essential for navigating an over-the-counter market that lacks standardized pricing and exposes corporate buyers to arbitrary markups. Because transaction prices vary wildly depending on buyer demographics, with financial and consumer-sector firms routinely paying 9% to 22% more than industrial buyers for identical credits, a trusted partner provides critical market intelligence to ensure fair benchmark pricing and protect against this opacity tax. Beyond price transparency, a reliable partner conducts deep due diligence to mitigate delivery and reputational risks, ensuring that credits stand up to public scrutiny regardless of market noise. Finally, expert guidance helps buyers verify genuine non-carbon co-benefits, such as certified UN Sustainable Development Goals, while steering clear of low-integrity, cheapest-to-deliver exchange pools so companies can build curated, high-impact offset portfolios.

💡 It’s important to note that while historical transaction data from 2018–2024 reflects an opaque market where prices were largely decoupled from actual climate effectiveness, today’s voluntary carbon market is undergoing a fundamental structural shift toward quality stratification. Driven by strict regulatory frameworks like the EU Corporate Sustainability Reporting Directive (CSRD) and integrity benchmarks like the ICVCM’s Core Carbon Principles (CCPs), the price-to-quality link is being actively restored. High-integrity, CCP-labeled credits now command a clear market premium, compelling corporate buyers to move away from unchecked environmental claims and toward auditable, risk-mitigated carbon portfolios.
💡 The collapse of standardized exchange-traded basket products proved that buyers actively reject generic carbon tokens in favor of specific, narrative-rich project attributes. Non-carbon co-benefits, such as biodiversity protection, local economic development, and verified UN Sustainable Development Goals, have shifted from optional marketing perks into non-negotiable procurement criteria. Consequently, successful developers and buyers are bypassing spot-market commoditization in favor of direct, long-term off-take partnerships that combine high-integrity nature-based solutions with high-durability removal pathways.
