Isometric has certified an update to the Biomass Feedstock Accounting Module. Version 1.3 expands the module’s scope to include new feedstocks such as invasive species and municipal waste, and provides suppliers with additional methods to demonstrate that their feedstocks meet module requirements—while maintaining the highest level of scientific rigour.
Certification follows a comprehensive 30-day public consultation that included feedback from buyers, suppliers, academics, and climate science researchers. Full details on the module’s evolution and how Isometric addressed feedback from the consultation are available in the module changelog and public consultation summary.
The updated module applies to all Biomass Carbon Removal and Storage (BiCRS) protocols—such as Biochar, Biogenic Carbon Capture and Storage, and Biomass Geological Storage—and serves as the central standard for Isometric’s biomass feedstock eligibility requirements and associated accounting principles.
Version 1.3 gives suppliers greater flexibility when designing their projects by enabling the use of additional residual biomass streams—including invasive species and municipal waste—that would otherwise go unutilized. This may unlock new project locations and, in the case of invasive species, helps suppliers transform threats to local ecosystems into climate solutions.
The update introduces additional methods for demonstrating that biomass feedstocks meet module requirements, including support for projects retrofitted onto existing facilities and processes such as bioenergy plants. The module has also been reorganized for clarity and provides expanded guidance for demonstrating feedstock eligibility.
This module update was developed in line with the Isometric Standard, through collaboration between Isometric’s in-house Science Team and reviewers from Isometric’s independent Science Network of more than 300 experts and practitioners.
