California: Heavy-duty: GHG

Overview

California’s Heavy-Duty Vehicle GHG Emission Reduction Regulation requires heavy-duty tractors and trucks 53 ft or longer to adopt fuel efficient tires and certain other devices that lower GHG emissions. 100% compliance was required for both large and small fleets by 2016.

Standard type
Greenhouse gas emission limits

Applicability
Heavy-duty tractors and 53 ft. or longer box-type semi-trailers that transport freight

History

In December 2008, the California Air Resources Board adopted the Heavy Duty Vehicle Greenhouse Gas Emission Reduction Regulation, a measure that requires long-haul truckers to install fuel efficient tires and aerodynamic devices on their trailers that lower greenhouse gas emissions and improve fuel economy.

The purpose of this regulation is to reduce greenhouse gas emissions from heavy-duty (HD) tractors and 53 ft. or longer box-type semitrailers (trailers) that transport freight on highways within California. The regulation does not apply to: drop-frame trailers; chassis trailers; curtain-side trailers; livestock trailers; refuse trailers; box-type trailers less than 53 feet in length; emergency vehicles; and military tactical support vehicles.

Technical Standards

Regulation

The regulation applies primarily to owners of 53 ft. or longer box-type trailers, including both dry-van and refrigerated-van trailers, and owners of the heavy-duty tractors that pull them on California highways. Owners are responsible for replacing or retrofitting their affected vehicles with compliant aerodynamic technologies and low rolling resistance tires. All owners must comply with the regulation when they operate their affected vehicles on California highways, regardless of where their vehicles are registered1

The tractors and trailers subject to this regulation must either use U.S. EPA SmartWay certified tractors and trailers, or be retrofitted with SmartWay verified technologies.

Tractors

The regulation was written such that beginning 1 January 2010, no 2011 or subsequent model year HD tractor, including sleeper-cabs tractors, pulling a 53-foot or longer box-type trailer would be allowed to operate on a highway within California unless such a tractor was a U.S. EPA SmartWay Certified Tractor. Additionally, as of 1 January 2013, no 2010 or previous model year HD tractor pulling a 53-foot or longer box-type trailer can operate on a highway within California unless such a tractor’s tires are U.S. EPA SmartWay Verified Technologies.

Trailers

As of 1 January 2010, no 2011 or subsequent model-year 53 ft. or longer dry-van trailer is allowed to travel on a highway within California unless such a trailer is either a U.S. EPA SmartWay Certified Trailer, or is equipped with both of the following: (1) tires that are U.S. EPA SmartWay Verified Technologies and (2) trailer aerodynamic technology-or combination of technologies as outlined in the regulation. The same applies to any refrigerated-van trailer. Similarly, as of 1 January 2013, any applicable 2010 or previous model year 53 ft. or longer dry-van trailer that is not participating in an optional trailer fleet compliance schedule must either be a U.S. EPA SmartWay Certified Trailer or must be equipped with a dry-van trailer aerodynamic technology or combination of technologies outlined in the regulation. Again, the same applies to any refrigerated-van trailer. By January 1, 2017, any non-exempt 2010 or previous model year 53 ft. or longer box-type trailer must be equipped with tires that are U.S. EPA SmartWay Verified Technologies.

Further information on the optional trailer fleet compliance schedule, as well as specific requirements for Drivers and Owners can be found within the regulation.

Schedule

Fleet size refers to the total of all 53-foot or longer box-type trailers within the owner’s fleet, including those operating outside of California. Fleet owners with a trailer fleet size of 21 or more trailers could elect to participate in either one of two compliance schedule options. A large fleet owner who failed to register for one of these options must bring all trailers in the fleet into compliance. A fleet owner with a trailer fleet size of 20 or fewer trailers could elect to participate in either of the large fleet compliance schedule options or in the small fleet compliance schedule described below.

Option 1

Table 1: Minimum Fleet Conformance Thresholds for the Large Fleet Compliance Schedule (Option 1)
Compliance Year Minimum Fleet Conformance Threshold Deadline
2010 5% 1 Jan 2011
2011 15% 1 Jan 2012
2012 30% 1 Jan 2013
2013 50% 1 Jan 2014
2014 75% 1 Jan 2015
2015 100% 1 Jan 2016
Notes:
† A trailer owner participating in Option 1 of this large fleet compliance schedule option must ensure that the percentage of compliant trailers on the compliance plan base list is equal to or greater than the applicable percentage.

Option 2

Table 1: Minimum Fleet Conformance Thresholds for the Large Fleet Compliance Schedule (Option 2)
Compliance Year Minimum Fleet Conformance Threshold Deadline
2010
2011 20% 1 Jan 2012
2012 40% 1 Jan 2013
2013 60% 1 Jan 2014
2014 80% 1 Jan 2015
2015 100% 1 Jan 2016
Notes:
† A trailer owner participating in Option 2 of this large fleet compliance schedule option must ensure that the percentage of compliant trailers on the compliance plan base list is equal to or greater than the applicable percentage.

Small Fleet

Table 3: Minimum Fleet Conformance Thresholds for the Small Fleet Compliance Schedule
Compliance Year Minimum Fleet Conformance Threshold Deadline
2013 25% 1 Jan 2014
2014 50% 1 Jan 2015
2015 75% 1 Jan 2016
2016 100% 1 Jan 2017
Notes:
† A trailer owner participating in the small fleet compliance schedule option must ensure that the percentage of compliant trailers on the compliance plan base list is equal to or greater than the applicable percentage.
