Earlier this month, the Environmental Protection Agency’s (EPA) Clean Air Scientific Advisory Committee (CASAC) released a draft set of recommendations calling on the EPA to tighten its current standard for ground-level ozone pollution to protect public health. But will the EPA follow CASAC’s recommendations?

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.
