    C

    is the number of vehicles in the fleet, and

    is the useful life of the vehicles of the fleet, expressed in miles;

  • (b) for vocational vehicles and incomplete vocational vehicles and subject to subsection 38(2) and clause 41(1)(b)(ii)(A),

    ECD = ((A – B) × C × D × E) ÷ (1 000 000)

    where

    ECD

    is the number of credits, if the result is positive, or the number of deficits, if the result is negative, expressed in megagrams of CO₂,

    A

    is the CO₂ emission standard under subsection 26(1), (1.1) or (1.2) that applies to the vehicles of the fleet or subfleet, as the case may be, expressed in grams of CO₂ per short ton-mile,

    B

    is the CO₂ family emission limit for the fleet or subfleet, as the case may be, expressed in grams of CO₂ per short ton-mile,

    C

    is the payload for the class of vehicles, which is

    • (i) 2.85 short tons for light heavy-duty vehicles,

    • (ii) 5.6 short tons for medium heavy-duty vehicles, and

    • (iii) 7.5 short tons for heavy heavy-duty vehicles,

    D

    is the number of vehicles in the fleet or subfleet, as the case may be, and

    E

    is the useful life of the vehicles of the fleet or subfleet, as the case may be, expressed in miles;

  • (c) for tractors and incomplete tractors and subject to subsection 38(2) and clause 41(1)(b)(ii)(B),

    ECD = ((A – B) × C × D × E) ÷ (1 000 000)

    where

    ECD

    is the number of credits, if the result is positive, or the number of deficits, if the result is negative, expressed in megagrams of CO₂,

    A

    is the CO₂ emission standard under subsection 27(1), (1.1) or (1.2) that applies to the tractors and incomplete tractors of the fleet or subfleet, as the case may be, expressed in grams of CO₂ per short ton-mile,

    B

    is the CO₂ family emission limit for the fleet or subfleet, as the case may be, expressed in grams of CO₂ per short ton-mile,

    C

    is the payload for the tractors and incomplete tractors, which is

    • (i) 12.5 short tons for Class 7 tractors and incomplete tractors,

    • (ii) 19 short tons for Class 8 tractors and incomplete tractors of the 2020 model year or an earlier model year and for Class 8 tractors and incomplete tractors of the 2021 model year or a subsequent model year that have a GCWR of less than 54 431 kg (120,000 pounds), and

    • (iii) 43 short tons for Class 8 tractors and incomplete tractors of the 2021 model year or a subsequent model year that have a GCWR of 54 431 kg (120,000 pounds) or more,

    D

    is the number of tractors and incomplete tractors in the fleet or subfleet, as the case may be, and

    E

    is the useful life of the tractors or incomplete tractors of the fleet or subfleet, as the case may be, expressed in miles; and

  • (d) for heavy-duty engines and subject to subparagraph 41(1)(c)(iii),

    ECD = ((A – B) × C × D × E) ÷ (1 000 000)

    where

    ECD

    is the number of credits, if the result is positive, or the number of deficits, if the result is negative, expressed in megagrams of CO₂,

    A

    is the CO₂ emission standard that applies to the fleet of heavy-duty engines under section 30 or subsection 31(2) or (5), as the case may be, expressed in grams per brake horsepower-hour,

    B

    is the CO₂ family certification level for the fleet, subject to subsection (3), expressed in grams of CO₂ per brake horsepower-hour,

    C

    is the transient cycle conversion factor calculated in accordance with the applicable variable “CF” in section 705(b) of Title 40, chapter I, subchapter U, part 1036, subpart H, of the CFR, except that a reference to “production volumes” in that section must be read as a reference to “number of engines of that engine family that a company imports or manufactures in Canada for the purpose of sale in Canada to the first retail purchaser”,

    D

    is the number of engines in the fleet, and

    E

    is the useful life of the engines of the fleet, expressed in miles.

• (2) [Repealed, SOR/2018-98, s. 39]

• Marginal note:Duty cycle

  (3) In the case of medium heavy-duty engines and heavy heavy-duty engines that are designed to be used in both vocational vehicles or incomplete vocational vehicles and in tractors or incomplete tractors, a company must select the duty cycle set out in paragraph 32(1)(b) that corresponds to the vehicle in which the engine is installed for the purpose of calculating the value determined for B in the formula set out in paragraph (1)(d).
