Mesa FAQ
Does the plan fine residents?
No. The Climate Action Plan sets policy direction; enforcement happens through specific ordinances like the energy code, water conservation rules, and building standards.
Why does Mesa run its own utilities?
Mesa is the only Arizona city operating water, natural gas, and electric as municipal utilities, giving it direct levers to implement climate goals across all three sectors.
Scottsdale FAQ
Why does Maricopa County not have a climate plan?
Arizona counties have limited general police power and no statutory mandate for climate planning. The Board of Supervisors has prioritized heat adaptation, air quality, and flood control programs rather than a binding GHG-reduction climate ordinance.
Does any climate rule cover unincorporated areas?
Federal Clean Air Act SIP rules and MCAQD ozone permitting still apply, and the Heat Relief Network provides voluntary services. There is no county greenhouse gas inventory, building electrification, or fleet conversion mandate.
