Relating to mass balance attribution of renewable biomass feedstocks used to produce renewable chemicals.

SB 2982 defines "renewable biomass" to include forest byproducts (like pre-commercial thinnings) and agricultural waste (such as crop residue, animal manure, and food waste), and "renewable chemicals" as products made from these feedstocks. The bill requires the Texas Commission on Environmental Quality to identify third-party certification systems that track how much renewable biomass is used in production (mass balance attribution). This applies directly to chemical manufacturers in Texas producing renewable chemicals, ensuring transparency in their supply chains. The law takes effect September 1, 2025, after the commission adopts implementing rules.
