Idle Free Schools Toolkit

sign says no idling children breathingEPA's toolkit includes information on running an effective idling reduction campaign at school in order to reduce student exposure to toxic vehicle exhaust. Resources are also provided to make the campaign a student-run science or community involvement project.

Why It's Important

  • Buses idling at schools can produce concentrated diesel exhaust emissions inside and outside schools.
  • Diesel exhaust can cause lung damage when inhaled and has been identified as a likely cause of cancer.
  • The soot and gases emitted by diesel engines are associated with:
    • Acute eye, throat and bronchial irritation
    • Exacerbation of asthma and allergies
    • Potential interference with lung development in children
  • In addition to impacting human health, diesel exhaust also harms the environment by contributing to smog formation and acid rain.
