Jurisdiction countryUnited States
Instrument typeprocurement
Authoritygovernment
Scopecarbon removal only
Statusexpired
DetailBill to create a California Carbon Dioxide Removal Purchase Program, successor to SB 308 (2023-24, died without passage). Passed both chambers with near-unanimous bipartisan support in 2025 but was vetoed by Governor Newsom on 2025-10-13 (not March 2026 — 2026-03-02 is the date the veto was formally sustained); recorded as terminal ('expired' used because the status taxonomy has no 'vetoed' value)
Monetary noteWould have established a state CDR purchase program (reported at up to ~USD 50M in public funding); Newsom's veto message cited budget constraints and pointed to SB 840's USD 85M climate innovation allocation as an alternative vehicle.
