I was doing a little gasoline reading after being on the "TBN zero" thread after realizing I had not been keeping up on gasoline the last several years. This is the link to the finalized EPA rules for Tier 3 that are effective this year.

Like the Tier 2 program, the Tier 3 program considers the vehicle and its fuel as an integrated system to reduce the impacts of motor vehicles on air quality and public health.

"In the 14 years since EPA established the Tier 2 Vehicle Program, manufacturers of light-duty vehicles and automotive technology suppliers have continued to develop a wide range of improved technologies capable of reducing vehicle emissions.... This technological progress has made it possible for manufacturers to achieve emission reductions well beyond the requirements of the Tier 2 program if gasoline sulfur levels are lowered further.
As a result, in conjunction with lower gasoline sulfur standards, we are establishing new Tier 3 standards for exhaust emissions "

"the program phases in over several years—with the primary vehicle emission standards starting in Model Year (MY) 2017 (2018 for heavier vehicles) and the gasoline sulfur control provisions beginning in 2017. "

I can't paste tables but emissions of NOX reduce to about 1/3 of the Tier 2 standards in 2025. How much of this is due to the low sulfur and how much is due to cars meeting the new CAFE requirements I don't know. I also don't know how close cars are now, from the read it definitely sounds like most are beating tier 2 even with more sulfur in the fuel.

I think this site is one of the best for understanding the different standards instead of reading the formal legal documents...

I read through the preamble. Biggest thing is cutting sulfur to 10ppm or less.
