Why Is Idling An Issue?

  • Idling is expensive: Idling may consume a gallon of fuel or more per hour, depending on the vehicle.
  • Idling threatens health: Breathing vehicle emissions increases the risk of respiratory illness, especially in children.
  • Idling pollutes: Emissions from vehicles combine in sunlight to form ground-level ozone pollution.

The Alamo Area Clean Cities Program can provide drivers technical assistance on alternative technologies to allow drivers to be comfortable and safe while saving money and reducing harmful emissions.
