Carbon credits

By permanently locking up the carbon from plant matter into a stable form with high-temperature exposure, biochar carbon removal (BCR) projects like ours produce carbon removal credits.

These credits represent measurable, data-driven and verifiable carbon removal, and we sell these to companies working to reach their net-zero targets.

Carbo Culture’s biochar’s long-term chemical and biological stability means it will persist unchanged over several lifetimes. As a result, our carbon credits are some of the most reliable on the market.

Permanence

Each carbon credit has its permanence; this is how stable the carbon sequestered is and how long it is likely to stay out of the atmosphere. Carbon credits created through biochar carbon removal (BCR) methods such as ours represent a far greater level of carbon stability.

Note on permanence from our team: We live in a very different world than just 100 years ago, let alone 1000 years ago. As the climate crisis worsens and our ice caps are melting within decades, carbon removal is needed in all its forms at unprecedented scale and at unseen speed. We are working with the new BCR science in geological timescales as it comes out, but in this crisis, 100 years of permanence is excellence. Let’s get to work.

High biochar stability

Biochar stability can be estimated by the ratio of hydrogen to carbon molecules it contains (H/Corg). This ratio is given a number between 0 and 1, where a number closer to 0 means higher permanence. Our certified ratio of 0.1-0.2 indicates a very high level of permanence, meaning the carbon that our credits represent stays out of the atmosphere for centuries.

We have two huge additional benefits to our biochar production method. Firstly, we have the unique ability to also produce large amounts of renewable energy: combined heat and power. This energy can reduce emissions by replacing fossil fuel use. Secondly, high-temperature biochars have repeatedly shown huge GhG reduction potential in peer-reviewed soil nutrient biochar incorporating studies, limiting N2O and methane from manure and fertilisers.

Our first facility, R1, is accredited by Puro.earth, the world’s leading crediting platform for engineered carbon dioxide removal (CDR) projects.

In a new market like the voluntary carbon market, third-party standards are essential to ensure measurement, reporting and verification across technologies. This includes laboratory tests and production data, showing that the carbon removal is and the project is free of any social or environmental harms.

Our pilot facility in California was the first Puro.earth accredited facility in North America. As we expand, R3 and C1 facilities will be certified once commissioned. The rigorous methodology Puro.earth has developed quantifies the net CO2 removal achieved over 100 years, from production to end-of-life.

For Carbo Culture, this calculation includes everything from our waste biomass all the way to the end use of our biochar in environmental applications. Our R1 accreditation includes a third-party life cycle assessment (conducted by Use Less), an independent audit by ELS, as well as laboratory analysis of material and ongoing verification of production data to certify our net carbon removal tonnage.
