The Tier 2 Vehicle and Gasoline Sulfur Program is a landmark program that affects every new passenger vehicle and every gallon of gasoline sold in the U.S. By designing cleaner cars that run on cleaner fuels the result is cleaner air. The program is a series of “firsts.” For the first time:
- SUVs, pickups, vans, and even the largest personal passenger vehicles are subject to the same national emission standards as cars;
- vehicles and the fuels they use are treated as a system, so the cleaner vehicles will have the low-sulfur gasoline they need to run their cleanest;
- new emission standards apply to all light vehicles, regardless of whether they run on gasoline, diesel fuel, or alternative fuels.
The Tier 2 Vehicle and Gasoline Sulfur program is part of a series of major initiatives that will reduce emissions from passenger vehicles, highway trucks and buses, and nonroad diesel equipment. The result will be reduced emissions, cleaner air, and improved human health.
