Motor vehicles, while an essential mode of transportation in a rural state like Vermont, are a major source of air pollutants that are associated with a variety of environmental and human health threats, including, but not limited to climate change, ground level ozone, air toxics, acid precipitation, and regional haze.
Mobile sources, primarily motor vehicles, are a significant source of air pollutants in Vermont including air toxics, the ozone precursors (volatile organic compounds and nitrogen oxides), and carbon monoxide. Motor vehicles also represent the largest source of greenhouse gas emissions in Vermont. 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.
