On March 3, 2014, EPA released its final rule on "Control of Air Pollution from Motor Vehicles: Tier 3 Motor Vehicle Emission and Fuel Standards" (the "Tier 3 rule"). A copy of the 1069-page Tier 3 rule is available online. A copy of EPA's five-page fact sheet on "EPA Sets Tier 3 Motor Vehicle Emission and Fuel Standards" is available online.


The Tier 3 rule is designed to reduce air pollution from passenger cars and trucks. Beginning in 2017, the Tier 3 rule will set new vehicle emissions standards and reduce the sulfur content of gasoline. It will treat the vehicle and its fuel as an integrated system. The final Tier 3 rule is very similar to the proposed version of the rule, although the final Tier 3 rule sets the ethanol content for emissions test gasoline at ten percent (E10) instead of at 15 percent (E15) as proposed.


The final Tier 3 rule is a part of the Obama Administration's efforts to combat the harmful impacts of climate change. It is expected to reduce several tons of harmful GHG emissions by 2030.
