Exomad Green and Supercritical have signed a three-year agreement covering up to 500,000 tonnes of durable carbon removal, marking one of the more important supply-side deals in the biochar market this year. The arrangement covers Exomad Green’s remaining 2026 inventory as well as forward allocations for 2027 and 2028, giving Supercritical access to a significant block of near-term, certified supply at a time when buyers are increasingly focused on credits that can be delivered and retired within the current decade.

The significance of the agreement lies not only in volume, but in timing. As more companies begin procuring against 2026 to 2030 climate targets, the market is shifting away from future pipeline promises and toward verified, operational production capacity. This deal reflects that change directly.

 

Biochar supply is becoming a premium part of the market

 

The agreement reinforces a broader trend in carbon removal: near-term, delivered supply is emerging as one of the most constrained parts of the market. While project announcements continue to grow, many early-stage removal pathways still face execution risk, delayed delivery timelines, or limited issuance. That is increasing the value of suppliers that can show real production, verified certification, and a record of delivery.

Exomad Green is positioning itself strongly in that category. The company says it has already produced more than 320,000 tonnes of durable carbon removal and has expanded production by more than 200% year on year. That scale gives the company a different commercial profile from many carbon removal suppliers that are still earlier in their operating development.

The market is rewarding delivered tonnes, not future ambition alone

 

One of the clearest messages in this transaction is that the carbon removal market is beginning to mature around performance rather than promise. Buyers are becoming more selective about what they are willing to contract, and the strongest demand is increasingly going to suppliers that can demonstrate reliable issuance and near-term availability.

This matters because the early years of carbon removal growth were often dominated by technology narratives, future scale projections, and pilot-stage momentum. The Exomad-Supercritical agreement shows a more practical phase beginning to take shape, where operational reliability and immediate access to durable credits are becoming decisive commercial advantages.

 

Supercritical is strengthening its role as a supply access platform

 

For Supercritical, the deal deepens a partnership that is already in its third year. The marketplace has already facilitated the sale of more than 100,000 tonnes of Exomad Green credits and says it has now facilitated nearly 2 million tonnes of carbon removal across multiple durable pathways, including biochar, mineralization, direct air capture, and enhanced rock weathering.

That gives the agreement broader relevance beyond a single supplier relationship. It suggests that marketplaces are becoming more than transaction venues. They are increasingly serving as structured channels through which buyers gain access to reliable supply from the few projects already operating at meaningful scale.

Near-term procurement is becoming more strategic

 

The timing of the agreement also reflects a wider shift in buyer behavior. Companies that once approached carbon removal more cautiously are now moving to secure forward access to supply before the market tightens further. As a result, long-term offtakes and near-term spot availability are both becoming important to market development.

In this context, the 500,000-tonne deal is not only a supply contract. It is also a signal about where buyer priorities are heading. Companies are no longer looking only for theoretical future access to carbon removal. They increasingly want volume that can be delivered within the next few years, especially where internal climate targets and procurement timelines are becoming more immediate.

 

What this agreement signals

 

The broader takeaway is that durable carbon removal is entering a more execution-driven phase. Exomad Green’s scale, verified output, and forward availability are exactly the qualities the market is starting to reward, while Supercritical’s role shows how procurement platforms are helping channel buyer demand toward proven producers.

If this trend continues, the next stage of carbon removal growth will likely be shaped less by who can announce the biggest future ambition and more by who can consistently deliver verified tonnes on commercial timelines. This agreement is a clear example of that shift taking place in real time.
