Impacts of idling
Idling engines can cause significant air pollution. An idling engine burns fuel less efficiently and can produce up to twice the emissions of a car that is moving. It pumps out unnecessary sulphur dioxide, particulate matter and nitrogen oxide into the atmosphere.
Vehicles idling while stationary not only cause an increase in harmful emissions, but also an unnecessary use of fuel plus create a noisy environment, especially for residents and businesses.
It is particularly important to avoid idling near schools because research shows that exposing children to high levels of air pollution can stunt lung growth, as well as causing behavioural and mental health problems.
