Bill Summary · SB 88

Legislative bill overview

SB 88 would modify California's carbon emissions accounting to treat biomass energy generation more favorably by potentially excluding or reducing emissions credits required for biomass combustion. The bill had bipartisan support in both chambers but was vetoed by the Governor in October 2025.

Why is this important

California uses carbon accounting to meet its climate goals, and how biomass is classified significantly affects renewable energy economics and forest management practices. The bill's treatment of biomass could influence whether forestry operations and wood waste facilities remain economically viable while also affecting the state's ability to meet emissions reduction targets.

Potential points of contention

  • Climate accounting accuracy: Biomass combustion releases carbon dioxide; the debate centers on whether emissions should be offset by assumptions about forest regrowth or carbon sequestration, which may not materialize
  • Forest management incentives: More favorable treatment could encourage thinning and forest management to reduce wildfire risk, but could also incentivize harvesting over preservation
  • Renewable energy economics: Favorable treatment makes biomass facilities more competitive against other renewable sources, potentially diverting investment from solar and wind development
