A very brief history of Corporate Average Fuel Economy
Originated in 1975 as part of the (Energy Policy and Conservation Act ‐ EPCA).
Long history of bi‐partisan support from many Congresses and Presidents.
Amended 2007 (Energy Independence and Security Act – EISA).
Requires Corporate Average Fuel Economy (CAFE) standards.
Requires DOT to set standards at maximum feasible levels for each fleet in each model year.
Requires DOT to enforce standards.

CAFE increases have helped the U.S. conserve a trillion gallons of gasoline.*

DOT has not yet proposed standards beyond 2021
Per EISA (2007), each CAFE rulemaking may cover at most 5 model years.
To establish final standards for model years 2022 and beyond, DOT must undertake a new rulemaking. The MY2017‐2021 light duty rule is final.
A July 2016 technical assessment (joint DOT, EPA, and CARB) began the process for 2022 and beyond.
DOT must consider a range of regulatory alternatives and cannot give any alternative special consideration.

The Light-Duty CAFE standards up through 2021 increase in stringency…
![Page 11: CAFE Standards Beyond 2021 - Latest Analysis and Next Step Presentations... · 9 DOT has not yet proposed standards beyond 2021 Per EISA (2007), each CAFE rulemaking may cover at](https://reader030.vdocument.in/reader030/viewer/2022040821/5e6ab6a0bb67cd6b096c7051/html5/thumbnails/11.jpg)

But Light-Duty CAFE standards are more complicated than one number…
Year‐by‐year fleet mix reallymatters

Recent CAFE activity (2016)
Late July 2016 ‐ EPA, NHTSA, and CARB published a “Draft Technology Assessment Report: Midterm Evaluation of Light‐Duty Vehicle Greenhouse Gas Emission Standards and Corporate Average Fuel Economy Standards for Model Years 2022‐2025”
Late September, 2016 ‐ Public comment period for Light Duty “Draft TAR” closed.
September 22, 2016 ‐ Congressional hearing for Light Duty CAFE.
August 16, 2016 – Medium duty / Heavy duty rule signed.

DOT leverages best available information to inform analysis
Technology characterizations (engine maps, transmission efficiency maps, etc.)
Full vehicle simulations for more than 100,000 combinations of technologies and equipment.
Projected year‐by‐year application of technology as the observed fleet evolves in response to standards (projected response includes practical factors like refresh/redesign cycles, shared platforms, manufacturer product portfolio, etc.)
Technology costs (including R&D spending, tooling amortization, etc.)
