Carbon removal marketplace Supercritical released market research titled The biocharBiochar is a carbon-rich material created from biomass decomposition in low-oxygen conditions. It has important applications in environmental remediation, soil improvement, agriculture, carbon sequestration, energy storage, and sustainable materials, promoting efficiency and reducing waste in various contexts while addressing climate change challenges. More supply crunch: Market intelligence for H2 2026, analyzing commercial procurement patterns in the global carbon dioxide removal (CDR) sector. The findings indicate that corporate buyers in the United Kingdom and global carbon markets are accelerating their procurement timelines, committing to 81% of the available high-quality biochar carbon credit supply by July 2026. This threshold was crossed three months earlier than in 2025. Excluding large single-buyer transactions from Microsoft, market-wide off-take volumes expanded tenfold in the first half of the year, increasing from 176,000 tonnes in H1 2025 to 1.81 million tonnes in H1 2026.

The report details a persistent structural challenge facing market participants: tight late-year supply constraints and substantial spot market price inflation. As corporate purchasers transition from ad hoc, short-term transactions to structured multi-year agreements, high-quality inventory becomes depleted rapidly within the first two quarters. Historically, this dynamic leaves minimal high-integrity supply available for second-half spot buyers, forcing late entrants to pay premium rates. For example, pricing data tracked by Supercritical showed credits from a single project rising from $155 per tonne in July 2025 to $185 per tonne by November 2025.

To address these market bottlenecks and facilitate long-term volume access, Supercritical provides enterprise buyers with direct inventory aggregation and structured procurement frameworks. The platform currently secures nearly half of the remaining high-quality biochar credits exclusively on its marketplace. Furthermore, ongoing enterprise requests for proposals (RFPs) hosted on the platform are positioned to absorb an additional 70% of the current unsold high-quality inventory, giving proactive buyers early access before second-half supply shortages materialize.

The outcome of these shifting buying habits is a constrained spot market for the second half of 2026, alongside a formal shift toward institutionalized carbon credit procurement. Biochar continues to lead the CDR sector, having delivered over twice the verified volume of all other permanent removal pathways combined. However, late-entering corporate buyers now face reduced inventory availability and higher acquisition costs, establishing early procurement as a strategic necessity for managing balance-sheet exposure to carbon offsets.
