Exomad Green and Supercritical Strike Biochar Carbon Removal Deal

Exomad Green and Supercritical have signed a major three-year agreement covering up to 500,000 tonnes of durable carbon removal, highlighting growing demand for high-quality, near-term carbon credits as the market matures.

The deal secures Exomad Green’s remaining supply for 2026, alongside future allocations for 2027 and 2028. All credits will be certified under the Puro.earth biochar methodology, reinforcing a focus on verified and high-integrity removal solutions. The agreement also builds on an existing partnership between the two companies, which has already facilitated the delivery of more than 100,000 tonnes of carbon removal.

The transaction reflects a broader shift in the carbon removal market, where buyers are increasingly prioritising credits that can be delivered and retired within shorter timeframes, particularly as corporate climate targets for 2030 approach. Rather than relying on long-term or early-stage project pipelines, demand is concentrating on operational projects with proven output.

Exomad Green has positioned itself at the centre of this trend, having delivered more than 320,000 tonnes of carbon removal to date and rapidly scaling production capacity. The company’s output growth—reported at over 200 per cent year-on-year—has helped establish it as the largest biochar-based carbon removal supplier globally by delivered volume.

For Supercritical, the agreement strengthens its role in aggregating and supplying high-quality carbon removal credits across multiple pathways. The company has now facilitated nearly two million tonnes of carbon removal transactions, spanning technologies such as biochar, mineralisation, direct air capture and enhanced rock weathering.

The deal also underscores tightening supply conditions in the near-term carbon removal market. As more corporate buyers enter the space and accelerate procurement strategies, access to reliable and immediately deliverable credits is emerging as a key differentiator. Execution risks among early-stage projects have further increased the value of established producers capable of consistent delivery.

Overall, the agreement signals a shift from early-stage market development towards a more performance-driven phase, where credibility, delivery timelines and operational track records are becoming central to how carbon removal credits are sourced and traded.
