The Maricopa County Board of Supervisors has not adopted a climate emergency declaration or countywide Climate Action Plan. Climate work happens through the Heat Relief Network, MCAQD ozone planning, and city-level CAPs in Phoenix, Tempe, and Mesa rather than a county mandate.
Unlike many California counties, Maricopa County has not declared a climate emergency or adopted a binding Climate Action Plan with greenhouse gas reduction targets. The Board of Supervisors instead funds adaptation programs administered by Maricopa County Department of Public Health and Human Services Department: the Heat Relief Network coordinates over two hundred cooling and hydration stations each summer, MCAQD enforces federal ozone and PM10 SIP rules, and the Flood Control District manages climate-driven storm risk. Phoenix adopted a 2021 Climate Action Plan, Tempe declared a climate emergency in 2019, and Mesa published a Sustainability Plan in 2022, but unincorporated residents are not bound by any countywide GHG ordinance.
There is no countywide climate emergency ordinance in Maricopa County, so no specific violations or penalties exist. City CAPs apply only inside the adopting municipality; unincorporated parcels remain governed by state and federal air rules.
