Additional Credits

Marginal note:Limitation

 A company must not obtain additional credits in accordance with sections 37 to 41 more than once for a vehicle or an engine with regard to the same type of greenhouse gas emission reduction technology.

Marginal note:Credit multiplier — Class 2B and Class 3 vehicles

 A company that obtains credits under paragraph 35(1)(a) for Class 2B and Class 3 heavy-duty vehicles and cab-complete vehicles that are electric vehicles, fuel cell vehicles, hybrid vehicles or are equipped with an engine that includes a Rankine-cycle or other bottoming cycle exhaust energy recovery system, may multiply the number of credits obtained for those vehicles by 1.5.

Marginal note:Equivalent conventional vehicle and footprint
  •  (1) For the purpose of the calculation in subsection (2),

    • (a) equivalent conventional vehicle means a vocational vehicle, incomplete vocational vehicle, tractor or incomplete tractor that is being compared with a vocational vehicle, incomplete vocational vehicle, tractor or incomplete tractor that is an electric vehicle, a fuel cell vehicle, a hybrid vehicle, or that is equipped with an engine that includes a Rankine-cycle or other bottoming cycle exhaust energy recovery system that has, as a minimum, the same footprint, class, coefficient of aerodynamic drag, tires and wheels, and has the same number of power take-off circuits and the equivalent take-off power as the vehicle in question; and

    • (b) footprint means the result of the product of the average width, measured in inches and rounded to the nearest tenth of an inch, of the lateral distance between the centrelines of the front and rear base tires at ground level, multiplied by the longitudinal distance between the front and rear wheel centrelines, measured in inches and rounded to the nearest tenth of an inch, divided by 144 and rounded to the nearest tenth of a square foot.

  • Marginal note:Calculation — tractors and vocational vehicles

    (2) In the case of vocational vehicles, incomplete vocational vehicles, tractors or incomplete tractors that are electric vehicles, fuel cell vehicles, hybrid vehicles or that are equipped with an engine that includes a Rankine-cycle or other bottoming cycle exhaust energy recovery system, a company may obtain additional credits by replacing the value determined for (A – B) in the equation set out in paragraph 35(1)(b) or (c), as the case may be, with the following benefit to emission credits, expressed in grams of CO2 per tonne-mile and determined by the equation

    (A – B) = improvement factor x modelling result B

    where

    improvement factor
    is the value determined by the formula

    (emission rate A – emission rate B) ÷ (emission rate A)

    where

    emission rate A
    is the emission test result, expressed in grams of CO2 per tonne-mile, obtained by an equivalent conventional vehicle when tested using the duty cycle test set out in section 510 of Title 40, chapter I, subchapter U, part 1037, subpart F, of the CFR, taking into account section 501 of Title 40, chapter I, subchapter U, part 1037, subpart F, of the CFR; and
    emission rate B
    is the emission test result, expressed in grams of CO2 per tonne-mile, obtained by the vehicle in question, as follows:
    • (a) for an electric vehicle, the result corresponds to 0 grams of CO2 per tonne-mile, and

    • (b) for any other vehicle, subject to subsection (3), the result obtained using the duty cycle test set out in section 510 of Title 40, chapter I, subchapter U, part 1037, subpart F, of the CFR, taking into account sections 501 and 525 of Title 40, chapter I, subchapter U, part 1037, subpart F, of the CFR; and

    modelling result B
    is the CO2 emission rate obtained for the vocational vehicle, incomplete vocational vehicle, tractor or incomplete tractor that is an electric vehicle, a fuel cell vehicle, a hybrid vehicle, or that is equipped with an engine that includes a Rankine-cycle or other bottoming cycle exhaust energy recovery system, when modelled in accordance with subsection 26(2) or subsection 27(2), as the case may be.
  • Marginal note:Emission rate B

    (3) In the case of fuel cell vehicles, the company may use the alternative procedure referred to in section 615 of Title 40, chapter I, subchapter U, part 1037, subpart G, of the CFR to calculate emission rate B in the equation set out in subsection (2).

  • Marginal note:Credit multiplier — tractors and vocational vehicles

    (4) The additional credits calculated in subsection (2) may be multiplied by 1.5 if the company does not use the early action credit multiplier referred to in subsection 47(6) for the same vehicles.

Marginal note:Definitions
  •  (1) The following definitions apply in this section:

    post-transmission hybrid system

    système hybride post-transmission

    post-transmission hybrid system means a powertrain that includes features that recover and store energy from braking but that cannot function as a hybrid system without the transmission. (système hybride post-transmission)

    pre-transmission hybrid system

    système hybride pré-transmission

    pre-transmission hybrid system means an engine system that includes features that recover and store energy during engine motoring operation but not from the vehicle wheels. (système hybride pré-transmission)

  • Marginal note:Calculation — post-transmission and pre-transmission hybrid systems

    (2) In the case of vocational vehicles, incomplete vocational vehicles, tractors and incomplete tractors that are equipped with post-transmission hybrid systems or pre-transmission hybrid systems, a company may obtain additional credits, expressed in megagrams of CO2, using the following formula:
