The Maricopa County Air Quality Department is launching a new campaign to encourage residents in the Phoenix metro area to reduce vehicle idling in order to help improve local air quality. The department is promoting the benefits of going 'idle-free' and providing resources for drivers to learn more about how idling impacts the environment.

Why it matters

Vehicle emissions from idling cars are a major contributor to air pollution in the Phoenix region, which has struggled with ozone and particulate matter levels that exceed federal air quality standards. By getting more drivers to shut off their engines when parked or stopped, the air quality department hopes to lower emissions and help residents breathe easier.

The details

The Maricopa County Air Quality Department is launching a new public awareness campaign called 'Care for Clean Air, Be Idle-Free.' The campaign will include educational materials, social media outreach, and partnerships with local organizations to spread the message about the importance of reducing unnecessary vehicle idling. The department cites research showing that just two minutes of idling can use the same amount of fuel as driving one mile, and that idling vehicles emit pollutants that contribute to smog, asthma, and other health issues.

  • The new 'Care for Clean Air, Be Idle-Free' campaign launched on April 8, 2026.
