2017 and Later Model Year Light-Duty Vehicle Greenhouse Gas Emissions and Corporate Average Fuel Economy Standards
NHTSA and EPA published in theFederal Registerof October 15, 2012, final rules to establish coordinated standards to improve fuel economy and reduce greenhouse gas emissions for vehicles manufactured for sale in the United States in model years 2017 and beyond. The final rules, consistent with President Obama's directive to the agencies on May 21, 2010, respond to the country's critical need to reduce oil consumption and address global climate change.
Need for Correction
As published, the final regulations inadvertently misprinted one of the values for “VMTu,” which represents lifetime vehicle miles traveled for the model year and compliance category in which a traded or transferred credit is used for compliance in 49 CFR part 536. The value printed for passenger cars in model year 2011 was “152,922,” when the value intended to be printed, consistent with prior rulemakings, is “150,922.” To correct the mistake, NHTSA is replacing the value in the table to alleviate any confusion.
List of Subjects in 49 CFR Part 536

Accordingly, 49 CFR part 536 is corrected by making the following correcting amendments:
PART 536—TRANSFER AND TRADING OF FUEL ECONOMY CREDITS
1. The authority citation for part 536 continues to read as follows:
49 U.S.C. 32903, delegation of authority at 49 CFR 1.50.
2. Revise § 536.4(c) to read as follows:
(c)Adjustment factor.When traded or transferred and used, fuel economy credits are adjusted to ensure fuel oil savings is preserved. For traded credits, the user (or buyer) must multiply the calculated adjustment factor by the number of its shortfall credits it plans to offset in order to determine the number of equivalent credits to acquire from the earner (or seller). For transferred credits, the user of credits must multiply the calculated adjustment factor by the number of its shortfall credits it plans to offset in order to determine the number of equivalent credits to transfer from the compliance category holding the available credits. The adjustment factor is calculated according to the following formula:
