Biochar is one of the most talked-about approaches in the carbon removals space. BeZero has now assessed the carbon efficacy and beyond carbon risks of many of the largest projects currently issuing credits. In the first of a two-part series, we summarise the key factors driving biochar projects’ headline BeZero Carbon Rating. Part two will cover Beyond Carbon and permanence risks.

Here are some key takeaways

Biochar credit quality varies significantly, underscoring the need for rigorous project-level due diligence.
Risks associated with biochar projects are largely driven by the type of biomass used,project setup and fugitive emissions
Tools such as BeZero’s Pre-rating Scorecard can help identify risks early in both pre- and post-issuance biochar projects that have not yet been rated.
