We are committed to preventing unnecessary engine idling in the borough to help lower vehicle emissions, improve local air quality and protect public health.
Following a public consultation which indicated support for further action, idling is now subject to enforcement action across Hounslow.
What is idling?
Idling is the act of leaving a vehicle's engine running while it is stationary.
Whilst this is often unavoidable for short periods of time, there are some instances, such as waiting for children outside of schools and in traffic jams, when idling is not necessary.
Why is idling bad?
It results in unnecessary use of fuel, an increase in emissions and can also create a noisy environment for residents, schools and businesses.
It's reported that an idling engine can produce up to 150 balloons of harmful exhaust emissions per minute, wastes half a gallon of fuel an hour and is a major contributor to the 9,000 premature deaths across London linked to air pollution (Air Quality News, 2019).
