The proposed regulation builds on the progress made under the Tier 2 program by setting new vehicle emissions standards and lowering the permitted sulfur content of gasoline, beginning in 2017. For an estimated cost of less than one cent per gallon of gasoline and less than $150 per vehicle, the proposed standards would significantly lower nitrogen oxides, volatile organic compounds, carbon monoxide, and fine particulate and air toxics emissions, saving thousands of lives and reducing air pollution-related hospitalizations every year. Consumers Union supports the proposed Tier 3 standards because they benefit vehicle owners, air quality, and public health. Consumers Union collected 31,068 signatures in support of the rule.
