CATF published the BiCRS Benchmark this month, a self-assessment instrument that scores biomass carbon removal protocols against 18 features drawn from a prior review of 25 public methodologies covering 94 underlying approaches.

The Clean Air Task Force built the benchmark from an expert panel convened to evaluate biomass production and transportation, pre-processing and bioconversion, long-term CO2 storage, and system accounting.

The panel's review of the 25 protocols documented significant variation in how each addressed those four components. That variation, CATF warned, creates risks of overlooked emissions, double-counted benefits, and other miscalculations in the atmospheric carbon dioxide credited to projects.

What does the tool actually do?

The BiCRS Benchmark lets a user run a protocol through the 18 features CATF classifies as critical for high-quality carbon dioxide removal. The scoring outputs benchmark against the highest-scoring approaches from CATF's original evaluation, allowing protocol developers, credit buyers, and registries to identify gaps and improvement opportunities.

CATF hosts the tool openly on its land-systems program page. It operates as a practical framework for self-assessment and methodology strengthening rather than a third-party certification scheme. A protocol author completes the assessment internally. CATF does not issue a pass or fail.

How did CATF build the criteria?

CATF convened a panel of scientists, engineers, and economists who examined 94 distinct protocol approaches during the original assessment. The 18 benchmark features distill the panel's findings into actionable checks covering feedstock sourcing, conversion efficiency, storage permanence, and accounting boundaries.

The four components map the project lifecycle from field to ledger. Biomass production and transportation covers feedstock origin, sustainability, and logistics. Pre-processing and bioconversion covers pyrolysis, gasification, and biological routes. Long-term CO2 storage addresses residence time and leakage risk. System accounting sets the rules for measuring net removal against baselines.

Why does protocol quality matter for the carbon market?

Biomass carbon removal sits among several CDR pathways corporate buyers and governments have evaluated as the voluntary carbon market expands and emissions-reduction commitments firm up. Inconsistent protocols undermine buyer confidence in credited tonnage, the currency of any carbon market.

Herbstritt framed the benchmark as a transparency instrument for a market where methodology quality varies widely. The 25 protocols reviewed diverged on how to define sustainable biomass, how to measure conversion efficiency, and how to verify storage.

"Biomass carbon removal has the potential to play an important role in a portfolio of carbon dioxide removal approaches, but strong protocols are essential to ensuring real climate benefits and to helping the industry scale," said Stephanie Herbstritt, Associate Director of Bioresource and Agricultural Engineering at CATF.

The benchmark lands as registries and policymakers work on standardization for bio-based removals including biochar and biomass with carbon capture and storage. International buyers increasingly require protocols that satisfy both regulatory criteria and private-sector durability expectations.

What changes from the original CATF assessment?

The original assessment functioned as a snapshot in time. Protocol authors revise their methodologies routinely, which prompted CATF to convert the analysis into an ongoing tool rather than a static report.

"Our initial assessment of carbon credit protocols represented a snapshot in time but protocols are routinely revised," Herbstritt said. "Our new tool supports registries and others seeking to strengthen their methodologies."

What comes next?

CATF has not announced a refresh schedule for the underlying methodology assessment, leaving open the question of how often benchmark scores will be updated. Registry adoption is the next test.

The tool enters a market where buyers demand verified, durable removals rather than offset claims. Protocols scoring well on long-term CO2 storage and system accounting will likely carry premium weight among institutional buyers.

Compared with voluntary frameworks that audit individual carbon removal projects, the BiCRS Benchmark audits the methodologies themselves. That distinction places the tool upstream of credit issuance, where a single protocol revision can shape every ton sold downstream for years.
