In Vermont, motor vehicles are the largest source of greenhouse gases and a number of other air pollutants that threaten human health and our environment. Unnecessary idling harms human health, pollutes the air, wastes fuel and money, and causes excess engine wear. And it’s against the law.
Mobile sources, primarily motor vehicles, represent the largest source of greenhouse gas emissions in Vermont and are a significant source of several other air pollutants including air toxics, the ozone precursors (volatile organic compounds and nitrogen oxides), and carbon monoxide. In order to reduce the impact of mobile source emissions on air quality and human health, the Mobile Sources Section implements and manages a number of programs and strategies for controlling on-road and non-road mobile sources of air pollution.
