The proposal is in response to President Obama's May directive to produce fuel consumption standards and CO2 emissions standards.
The regulations will be tailored to each of three regulatory categories of heavy-duty vehicles:
- Combination tractors;
- Heavy-duty pickup trucks and vans;
- Vocational vehicles;
- Gasoline and diesel heavy-duty engines.
The agency is also requesting comment on possible alternative CO2-equivalent approaches for model year 2012-14 light-duty vehicles. The GHG standards would begin with model year 2014. NHTSA's proposed fuel consumption standards under the Energy Independence and Security Act of 2007 would be voluntary in model years 2014 and 2015, becoming mandatory with model year 2016 for most regulatory categories.
Commercial trailers would not be regulated in this phase of the Heavy-Duty National Program, although there is a discussion of the possibility of future action for trailers.
Comments on all aspects of this proposal must be received on or before Jan. 31, 2011.
