There are many human-made sources of emissions, and on-road motor vehicles, such as cars, are a huge driving factor in air pollution. Motor vehicle exhaust is one big source of ground-level ozone or smog, fine particulate matter, carbon monoxide and nitrogen dioxide.

Getting more zero- and low-emission vehicles on the road in Pennsylvania helps reduce harmful air pollutants, including nitrogen oxides, carbon monoxide, particulate matter, and volatile organic compounds. It also helps lower the level of carbon dioxide, one of the greenhouse gases heating up the climate, in the air.

Like nitrogen dioxide, methane combines with other pollutants to form ground-level ozone—more commonly known as smog—and it is a significantly more potent global warming pollutant than carbon dioxide. The EPA, however, does not have the authority to regulate indoor air pollution from household appliances.

Since global and local pollutants are often byproducts of the same activities, mitigation policies for global warming emissions have the potential to simultaneously mitigate local air pollution 2. One good example of the nexus between global warming and local pollution is ground-level ozone.
