The Voluntary Carbon Market Roars Back to Life in 2025, But Who's Really Driving the Growth?
After two years of stagnation, the voluntary carbon market (VCM) experienced a dramatic resurgence in 2025, according to AlliedOffsets' latest review (https://alliedoffsets.com/wp-content/uploads/2025/12/2025-VCM-Overview-Report.pdf). But here's where it gets intriguing: this growth wasn't evenly distributed. AlliedOffsets, a leading firm in carbon market analysis (https://www.linkedin.com/company/alliedoffsets/), delved into its extensive database, tracking over 36,000 projects across 35+ registries, 28,000+ corporations, and billions of tons of carbon credits, to uncover the key trends shaping the VCM's revival.
A Year of Records and Shifting Landscapes
2025 saw carbon retirements surpass 2024 levels, offtakes reach unprecedented highs, and the total market value breach the $10 billion mark for the first time since AlliedOffsets began monitoring the VCM in 2020. This resurgence wasn't just about numbers; it signaled a structural shift towards carbon removals. However, a closer look reveals a concentration of demand among a select group of buyers, countries, and project types, despite improvements in policy support and standards.
Growth, But Not for Everyone?
While retirements and offsets grew by approximately 100 million tons compared to 2024, the number of unique buyers remained relatively unchanged. This suggests a trend where a limited group of players is driving the bulk of the growth. Interestingly, 2025 witnessed the emergence of first-time buyers from Asia and parts of Europe, hinting at a potential geographic diversification of demand in the coming years.
Biomass Reigns Supreme, But for How Long?
Issuance volumes hit an all-time high, primarily driven by deals involving biochar, bio-utilization, and BECCS (Bioenergy with Carbon Capture and Storage), highlighting the continued dominance of biomass-based carbon removal methods. Carbon removal offtake deals skyrocketed by 305% between 2024 and 2025, with Microsoft leading the charge. However, despite this surge in transactions, overall investment in carbon dioxide removal (CDR) slowed down in 2025, raising questions about the sustainability of this growth.
The US Leads, But Who Follows?
The United States maintained its position as the leading purchaser and supplier of CDR projects, followed by mature markets like the UK, the Netherlands, and Canada. This concentration of activity begs the question: are we seeing a truly global market emerge, or is the VCM still reliant on a handful of key players?
Policy Support Grows, But Challenges Remain
2025 saw strengthened policy and integrity support for the VCM, with 50% of compliance and regulatory schemes either accepting offsets or considering their inclusion. However, limitations persist, such as the constrained supply of CORSIA Phase 1 credits due to limited availability of correspondingly adjusted credits. This highlights the ongoing need for robust infrastructure and standardized mechanisms to ensure the market's long-term viability.
Cautious Optimism for the Future
Reflecting on the year, Anton Root, Head of Research at AlliedOffsets, remarked, “2025 marked a year of resilience for the VCM. After restructuring, retooling, and learning from past mistakes, companies are entering the new year with a sense of cautious optimism, hoping that the worst may finally be behind them.”
The Million-Dollar Question: Is This Growth Sustainable?
While 2025 brought significant growth and positive developments, the concentration of demand and reliance on a few key players raise concerns about the VCM's long-term sustainability. As the market continues to evolve, will we see a broader base of participants, or will it remain dominated by a select few? The answer to this question will be crucial in determining the VCM's ability to effectively combat climate change.
