$213 Per Tonne: Inside the Latest Multi-Pathway CDR Deal

The carbon removal market just got another major signal that demand for durable solutions is accelerating. ClimeFi, the London-based carbon removal procurement platform, has closed an $18 million procurement round spanning 85,000 tonnes of CO₂ removal at an average price of $213 per tonne.

This deal stands out for its diversity. It covers eight different removal pathways, signaling a shift away from single-technology reliance. Corporate buyers pooled demand to secure preferential terms and volume discounts, a model that could reshape how companies approach carbon removal purchasing.

The suppliers selected include some of the most recognized names in durable carbon removal, with 71% of volume commitments coming from the Americas.

North American Suppliers Take Center Stage

The Americas dominated this procurement round, and for good reason. The region hosts some of the most advanced carbon removal operations currently scaling. Three U.S. and Canadian suppliers stood out in ClimeFi's selection:

1. Graphyte (Arkansas, USA)

Graphyte uses its proprietary Carbon Casting process to dry and compress biomass into dense carbon blocks for underground storage. The company recently raised $30 million in Series A funding and operates a facility in Arkansas targeting 50,000 tonnes of removal capacity annually.

2. Deep Sky (Canada)

Deep Sky made headlines in 2025 when it launched Deep Sky Alpha, North America's first facility to permanently store CO₂ captured directly from the air. The Alberta-based innovation center hosts multiple direct air capture technologies under one roof.

3. Vaulted Deep (USA)

Vaulted Deep converts organic waste into permanent carbon storage by injecting bioslurry deep underground. The company recently won $8 million in the XPRIZE Carbon Removal competition and secured a landmark 4.9 million tonne deal with Microsoft.

Pathway Diversification Signals Market Maturity

Unlike earlier procurement rounds that leaned heavily on one or two technologies, this deal spread across eight distinct pathways. Biochar took the largest share, followed by enhanced rock weathering and terrestrial biomass sequestration.

The full list of technologies includes:

1. Biochar
2. Bioenergy with Carbon Capture and Storage (BECCS)
3. Direct Air Capture and Storage
4. Enhanced Rock Weathering
5. Microbial Carbon Removal
6. Mineralisation
7. Terrestrial Biomass Sequestration
8. Wastewater Alkalinity Enhancement

This diversification matters because it spreads risk across multiple technology development tracks. If one pathway faces scaling challenges, the portfolio remains resilient.

Delivery Timeline and Storage Methods

The bulk of fixed volume commitments will arrive in 2027 and 2028, with options extending through 2033. This long-term structure reflects growing buyer confidence in locking in removal capacity ahead of corporate net-zero deadlines.

Storage methods span three categories: stabilised biomass, mineralisation, and geological storage. Each offers different permanence profiles, allowing buyers to build portfolios aligned with their specific climate commitments.

What This Means for the Market

The $213 per tonne average sits firmly in the premium removal credit range. This aligns with broader market trends showing high-quality credits trading at roughly 30% premiums over lower-tier alternatives.

ClimeFi's pooled procurement model offers smaller buyers access to pricing and terms typically reserved for large corporate purchasers. By aggregating demand, the platform helps companies secure removal capacity without the overhead of direct negotiations with multiple suppliers.

The company plans to announce specific buyer-project collaborations in the coming weeks, which will reveal more about the corporate appetite driving these deals.

Building Momentum for Durable Removals

This procurement round arrives at a pivotal moment. The durable carbon removal market officially crossed the 1 million tonne mark in deliveries during 2025, signaling the industry's shift from pilot projects to commercial operations.

ClimeFi will continue monitoring these projects for potential risks, including credit issuance delays and non-delivery concerns. For buyers seeking verified, permanent carbon removal, multi-pathway portfolios like this one offer both diversification and credibility in an increasingly competitive market.
