Missouri's state-level posture on energy-choice municipal regulation. HB 734 (2021) — signed by then-Gov. Mike Parson (R), prohibits local governments from enacting ordinances restricting utility service based on fuel source. Parallel to AZ HB 2686 (2020), TN 2020, OK HB 3619 (2020), LA R.S. 30:2379 (2020), AR Act 308 (2021). Missouri is in Pluribus News preemption-state list (GA/TX/FL/MS/MO/TN/LA/OK). Per KCUR September 2022 ("When Kansas City designed a climate plan, its hands were tied by a 2021 Missouri law") and Kansas City Beacon coverage, HB 734 structurally constrained Kansas City's 2022 Climate Protection and Resiliency Plan — the most-documented state-local preemption constraint on a climate plan surveyed in this research pass. KC's climate plan explicitly notes HB 734 constraints on aggressive energy-source municipal regulation. Does not name lawn equipment but energy-choice framing shadows any fuel-source municipal ordinance. Gov. Mike Kehoe (R, inaugurated January 2025) continues Parson energy-forward framework; signed major utility bill April 2025. No GLB-specific EO. No state GLB/SORE bill in 2024 or 2025 Missouri Legislative Sessions.
