Per CARB's February 2026 regulation (Rev. & Tax. Code §23101, as narrowed by CARB): organized or commercially domiciled in California, or California sales above $757,070 (2025, inflation-indexed) or 25% of total sales. Property- or payroll-only presence does not count.

SB253list.com is an independent public resource tracking California's climate disclosure laws. This tool reports whether a company appears on the California Air Resources Board's preliminary list of covered entities (published September 24, 2025), shown exactly as CARB lists it. Per CARB: "Each potentially-regulated entity remains responsible for compliance with statutory requirements, regardless of whether it was included in staff's preliminary list." Inclusion is not a final determination of coverage and absence is not an exemption. Both laws are under constitutional challenge; SB 261 enforcement is currently enjoined.
