Think twice before resurrecting burned offset projects
For the first time, a landowner is looking to re-enroll a forest that was part of a project terminated after a catastrophic fire. While this practice is legal, it has potentially negative consequences for California’s buffer pool.

Lime is used to manage soil pH in many agricultural fields and can remove carbon from the atmosphere when it weathers. We are updating our CDR Verification Framework tool to emphasize that changes in lime use and weathering should be accounted for in enhanced weathering and biochar deployments.

New reporting indicates that the wildfire component of California's buffer pool is almost surely depleted.

We added new pathways (direct ocean removal, alkaline waste mineralization, and biochar), modified existing pathways, and upgraded the tool with improved versioning, additional documentation, and the ability to see how components are shared across pathways.

Relying on public data, our recent seaweed farming modeling work made key assumptions about seaweed cultivation. We summarize why making these assumptions was necessary, and why as a result the modeled costs may not capture current advances taking place in the field.

We summarize two recent comment letters about Verra’s proposed use of ton-year accounting to issue carbon offset credits — including via a proposed methodology developed by NCX which would credit harvest deferrals as short as a single year.
