What makes a high-quality credit

A carbon credit represents one metric ton of carbon dioxide removed from the atmosphere or kept out of it. Quality varies, and buyers look at three things.


  • Permanence

    Biochar locks carbon into a stable solid instead of letting it return to the atmosphere.


  • Verification

    Every credit is backed by monitoring, reporting and independent third-party verification.


  • Real impact

    Biochar credits come from carbon actually removed, with added benefits for soil and local communities.

Built to the leading standards

Our projects are designed for certification under leading international carbon removal standards, ensuring integrity, transparency and permanence. Each project follows rigorous monitoring, reporting and third-party verification to confirm durable carbon storage.


  • Puro.earth


  • Verra (VCS)


  • Carbon Standards International

We engage certification bodies early, design every project around approved biochar methodologies and run robust monitoring and data systems from the start, so verification and credit issuance stay on schedule.

How credits reach buyers

Pre-purchase and offtake agreements

To give buyers secure supply and each plant predictable revenue, we prioritize pre-sales and multi-year offtake agreements with corporate buyers, locking in demand before credits are issued.

Leading carbon removal marketplaces

Credits will also be listed on leading carbon removal marketplaces, where biochar credits regularly sell out.

Demand is outpacing supply

Global demand for high-quality carbon removal is growing fast as companies move beyond low-quality offsets toward permanent, verifiable solutions. Biochar is one of the most scalable and cost-effective forms of durable carbon removal available today, yet supply remains limited, especially from projects with strong verification and long-term storage.

Large buyers already hold contracts with existing providers and are actively looking for new verified projects. That gap is what 11BIO is built to fill.
