Biochar Protocol

The Climate Action Reserve is developing a Biochar Protocol that will provide guidance on how to quantify, monitor, report, and verify climate benefits from the production and use of biochar, which is capable of locking up carbon and keeping it from re-entering the atmosphere for centuries. Biochar production provides an opportunity for the productive use of a variety of feedstocks that are otherwise considered waste biomass, including non-merchantable residues from timber harvests and fuel thinnings.

Kickoff Webinar

The Reserve hosted a public webinar on August 12, 2021 to kickoff the Biochar Protocol development process.


The Biochar Protocol is being developed through the Reserve’s multi-stakeholder workgroup process. The Reserve strives to create a well-balanced workgroup consisting of industry representatives, project developers, environmental NGOs, verification bodies, independent consultants, academia, and government bodies.

Workgroup member organizations are listed below:

ACT Commodities Placer County Air Pollution Control District
Arq Royal Dutch Shell
Aster Global Sonoma Ecology Center
Biochar Solutions South Pole
Blue Forest Conservation SUNY College of Environmental Science & Forestry
Cornell University U.S. Forest Service
International Biochar Initiative University of California-Berkeley
GECA Environment Viresco Solutions Inc.
Humboldt State University, Schatz Energy Research Center Woodwell Climate Research Center
Pacific Biochar World Resources Institute

Stakeholders not chosen to be part of the workgroup are encouraged to participate in the process as “observers.” Observers may attend workgroup meetings in listen-only mode, submit written comments on the draft methodology when it is available for public comment, and attend the public webinar held during the public comment period.

Workgroup Meeting

Biochar Workgroup Meeting 1 (November 4, 2021) and Follow Up Meeting (November 16, 2021)

Market Analysis and Pilot Projects

The development of the protocol will be accompanied by a market analysis evaluating the potential scale of credits that can be produced from biochar and the anticipated demand for such credits. The analysis will be developed by Blue Forest, who is also providing financial support for the analysis courtesy of funding from the Doris Duke Charitable Foundation, with advisory services provided by Daniel Sanchez, Assistant Specialist in Department of Environmental Science, Policy, and Management at the University of California-Berkeley.

Additionally, several pilot projects (provided by Pacific Biochar, Biochar Solutions, and additional biochar producers yet to be determined) will be developed alongside the protocol to test viability of offset project requirements.
