SBP Publishes Landmark Guidance for US REDIII Level B LULUCF Assessments

The Sustainable Biomass Program (SBP) has today announced the publication of the Guidance for US REDIII Level B LULUCF v1.0, marking a major milestone for SBP and the wider biomass sector.

This works presents a comprehensive, country‑wide assessment of forest carbon stocks and stock changes across the contiguous United States. Through commissioning leading international experts, SBP has published a rigorous, science‑based resource that supports robust compliance with the EU Renewable Energy Directive (REDIII).

The Guidance provides Biomass Producers with a detailed basis for assessing historical and projected carbon stocks, helping them identify areas where carbon stocks may be at risk and determine where targeted mitigation measures are required. An accompanying carbon‑stock assessment tool further enables producers to adapt the results to their specific sourcing areas, ensuring clarity and confidence in meeting the requirements of REDIII Article 29(7) Level B.

This work arrives at a pivotal time for the sector. Following updates to US LULUCF risk classifications and the shift from Level A to Level B under REDIII, Biomass Producers sourcing from US forests will be required to meet new compliance obligations from 27 January 2026. SBP’s Guidance provides the methodological support and evidence base needed to help operators navigate this transition effectively.

The Guidance for US REDIII Level B LULUCF v1.0 and accompanying carbon‑stock assessment tool are available now on the SBP website here.
