Cleaner cars, cleaner air
Have you noticed those PZEV labels on new cars? That stands for “Partial Zero Emissions Vehicle” and it’s a big deal for Utah air quality.
After the 2017 model year, the automobile industry is planning to install PZEV technology in all new cars to comply with nationwide Tier 3 motor vehicle emissions and fuel standards set by the U.S. Environmental Protection Agency (EPA). The Chevron and Tesoro refineries in Davis County are installing equipment to produce low-sulfur Tier 3 gasoline. The Utah Legislature has passed a law giving refineries a tax break to help make the change to Tier 3 fuels.
Tier 3 won’t help with CO2 emissions that cause climate change, but the rules could help us all breathe more easily.
