1 Sub-category terms are defined in the applicable test procedures incorporated by reference in section (d).
1. CO2 Fleet-Average Standards. For each model year, a manufacturer's national fleet-average CO2 emissions for its diesel medium-duty vehicles shall not exceed the CO2 fleet-average standard. The CO2 fleet-average standard is calculated from the target value for each vehicle subconfiguration (Targeti) and U.S.-directed production volume of each vehicle subconfiguration for the given model year (Volumei), as follows:
Fleet Average Standard | = | Σ[Targeti x Volumei] | ||
Σ[Volumei] |
Round the fleet-average standard to the nearest 0.1 g/mile. The target values, for each vehicle configuration, are calculated as follows:
CO2 Target (g/mile) = 0.0416 x WF + 320
where WF is the work factor.
WF = 0.75 x (GVWR - Curb Weight + xwd) + 0.25 x (GCWR - GVWR)
Where:
xwd = 500 pounds if the vehicle has four-wheel drive or all-wheel drive; xwd = 0 pounds for all other vehicles.
Phase 1 Option A Phase-In Provisions for Diesel Fleet-Average CO2 Target

2026 | 0.0357 x (WF) + 275 |
2027 and later | 0.0348 x (WF) + 268 |
b. Useful Life Provisions. A medium-duty vehicle must comply with the emission standards in this subsection (b)(1)(A) throughout its full useful life, of 11 years or 120,000 miles, whichever occurs first, for 2014 through 2020 model year vehicles (Phase 1), and of 15 years or 150,000 miles for 2021 and later model year vehicles (Phase 2).
c. Production and In-use CO2 standards. Each vehicle a manufacturer produces that is subject to the standards of this section has an “in-use” CO2 standard that is calculated from the test result and that applies for selective enforcement audits and in-use testing. This in-use CO2 standard for each vehicle is equal to the applicable deteriorated emission level multiplied by 1.10 and rounded to the nearest 0.1 g/mile for Phase 1 vehicles and nearest whole g/mile for Phase 2 vehicles.
2. N2O and CH4 Emission Standards. The N2O emissions for new 2014 and subsequent model medium-duty vehicles shall not exceed 0.05 g/mi, and CH4 emissions for new 2014 and subsequent model medium-duty vehicles shall not exceed 0.05 g/mi. Alternate standards using CO2 emission credits may be used and are described in the “California Green-house Gas Exhaust Emission Standards and Test Procedures for 2014 and Subsequent Model Heavy-Duty Vehicles,” incorporated by reference in section (d).
1. CO2 Fleet-Average Standards. For each model year, a manufacturer's national fleet-average CO2 emissions for its Otto-cycle medium-duty vehicles shall not exceed the CO2 fleet-average standard. The CO2 fleet-average standard is calculated from the target value for each vehicle subconfiguration (Targeti) and U.S.-directed production volume of each vehicle subconfiguration for the given model year (Volumei), as follows:
Fleet Average Standard | = | Σ[Targeti x Volumei] | ||
Σ[Volumei] |
Round the fleet-average standard to the nearest 0.1 g/mile. The target values, for each vehicle configuration, are calculated as follows:
CO2 Target (g/mile) = 0.0440 x WF + 339
where WF is the work factor.
WF = 0.75 x (GVWR - Curb Weight + xwd) + 0.25 x (GCWR - GVWR)
Where:
xwd = 500 pounds if the vehicle has four-wheel drive or all-wheel drive; xwd = 0 pounds for all other vehicles.

2026 | 0.0378 x (WF) + 291 |
2027 and later | 0.0369 x (WF) + 284 |
b. Useful Life Provisions. A medium-duty vehicle must comply with the emission standards in this subsection (b)(1)(B) throughout its full useful life, which is 11 years or 120,000 miles, whichever occurs first, for 2014 through 2020 model year vehicles (Phase 1), and of 15 years or 150,000 miles for 2021 and later model year vehicles (Phase 2).
c. Production and In-use CO2 standards. Each vehicle a manufacturer produces that is subject to the standards of this section has an “in-use” CO2 standard that is calculated from the test result and that applies for selective enforcement audits and in-use testing. This in-use CO2 standard for each vehicle is equal to the applicable deteriorated emission level multiplied by 1.10 and rounded to the nearest 0.1 g/mile for Phase 1 vehicles and nearest whole g/mile for Phase 2 vehicles.
2. N2O and CH4 Emission Standards. The N2O emissions for new 2014 and subsequent model medium-duty vehicles shall not exceed 0.05 g/mi, and CH4 emissions for new 2014 and subsequent model medium-duty vehicles shall not exceed 0.05 g/mi. Alternate standards using CO2 emission credits may be used and are described in the applicable test procedures incorporated by reference in section (d).
(1) Phase 2 Emission Standards for Trailers. The exhaust emission standards specified in this subsection apply to trailers based on the effect of trailer designs on the performance of the trailer in conjunction with a tractor; this accounts for the effect of the trailer on the tractor's exhaust emissions, even though trailers themselves have no exhaust emissions.
e. Note that the definition of “trailer” in 40 CFR § 1037.801, as amended October 25, 2016, excludes equipment that serves similar purposes but are not intended to be pulled by a tractor. This exclusion applies to such equipment whether or not they are known commercially as trailers. For example, any equipment pulled by a heavy-duty vehicle with a pintle hook or hitch instead of a fifth wheel does not qualify as a trailer under this part.
a. For trailers 35 feet or longer, a manufacturer may designate as “non-aero box vans” those box vans that have a rear lift gate or rear hinged ramp, and at least one of the following side features: side lift gate, side-mounted pull-out platform, steps for side-door access, a drop-deck design, or belly boxes that occupy at least half the length of both sides of the trailer between the centerline of the landing gear and the leading edge of the front wheels. For trailers less than 35 feet long, a manufacturer may designate as “non-aero box vans” any refrigerated box vans with at least one of the side features identified for longer trailers.
b. A manufacturer may designate as “partial-aero box vans” those box vans that have at least one of the side features identified in subsection (c)(1)(B)1.a. Long box vans may also qualify as partial-aero box vans if they have a rear lift gate or rear hinged ramp. Note that this subsection (c)(1)(B)1.b. does not apply for box vans designated as “non-aero box vans” under subsection (c)(1)(B)1.a.

d. Averaging, Banking, and Trading Program. The requirements for the optional averaging program, which begins in model year 2027, are described in the applicable test procedures incorporated by reference in section (d). A manufacturer may not use averaging for non-box trailers, partial-aero box vans, or non-aero box vans that meet standards under subsection (c)(1)(B)2.b. or (c)(1)(b)2.c. of this section, and a manufacturer may not use emission credits for banking or trading for any trailers.
(d) The test procedures for determining compliance with GHG emission standards applicable to 2014 and subsequent model medium- and heavy-duty vehicles are set forth in the “California Greenhouse Gas Exhaust Emission Standards and Test Procedures for 2014 and Subsequent Model Heavy-Duty Vehicles,” adopted October 21, 2014, as last amended September 9, 2021, which is incorporated by reference herein.
