Idling vehicles contribute to air pollution and emit air toxins, which are pollutants known or suspected to cause cancer or other serious health effects. Limiting a vehicle’s idling time can dramatically reduce the amount of pollutants and exposure to them. If your company does not already have an anti-idling policy in place, you can use our sample anti-idling policy and modify it as needed to reduce emissions on-site. The policy includes guidance, exceptions, and how it can be monitored and enforced.
