Tier 3 standards will help us reduce air pollution in two ways:
- By reducing sulfur levels in gasoline, so what you put into your car is cleaner and
- By improving cars' emission systems, so what comes out of your car is cleaner.
That will reduce the soot, smog and other types of dangerous pollution that come from the tailpipes of our cars and trucks.
The Tier 3 standards are designed to work in harmony with America's new clean car standards, which will improve fleet-wide fuel efficiency in new cars. Lower sulfur levels in gasoline will also allow vehicles to run more efficiently.
The Tier 3 standards go into effect in 2017.
By 2030, the impact of emission reductions from these tightened fuel and vehicle standards will be:
- 2,000 premature deaths prevented.
- 2,200 hospital admissions and asthma-related emergency room visits prevented.
- 19,000 asthma attacks prevented.
- 30,000 upper and lower respiratory symptoms in children prevented.
- 1.4 million prevented lost school days, work days and days of minor-restricted activities.
All of these avoided health impacts are worth as much as $19 billion every year.
And we get all of this for the cost of well under a penny per gallon of gas.
