Grouping into Fleets

Marginal note:Election applicable to all vehicles and engines

 If a company makes the election referred to in subsection 22(4), 26(7), 27(8) or 33(1) for a fleet of heavy-duty vehicles or heavy-duty engines that it manufactures or imports, that election applies to all the vehicles and engines of that fleet.

Class 2B and Class 3 Heavy-duty Vehicles

N2O and CH4 Emissions

Marginal note:Standards
  •  (1) Class 2B and Class 3 heavy-duty vehicles and cab-complete vehicles of the 2014 and subsequent model years — excluding those referred to in the definition vocational vehicle in subsection 1(1) — must have N2O and CH4 emission values that do not exceed 0.05 g/mile for N2O or 0.05 g/mile for CH4 for the applicable useful life of the vehicle.

  • Marginal note:Calculation

    (2) The N2O and CH4 emission values must be calculated in accordance with section 24.

  • Marginal note:Fleet calculation

    (3) A company that manufactures or imports vehicles referred to in subsection (1) that exceed any of the standards set out in that subsection must group those vehicles of a given model year into a fleet and subfleets in accordance with section 18 and must calculate the N2O and CH4 emission deficits for that fleet, expressed in megagrams of CO2 and rounded in accordance with subsection 35(2), by adding the deficits for all those subfleets, if applicable, using the formula

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

    where

    A
    is 0.05 g/mile for N2O and 0.05 g/mile for CH4;
    B
    is the N2O or CH4 family emission limit for the fleet or subfleet, as the case may be, and corresponds to the N2O or CH4 emission value calculated in accordance with section 24;
    C
    is the number of vehicles in the fleet or subfleet, as the case may be;
    D
    is the useful life for the vehicle, namely, 120,000 miles; and
    E
    is the global warming potential and is equal to the following number of credits needed to offset a N2O and CH4 deficit:
    • (a) an emission credit of 298 Mg of CO2 to offset a deficit of 1 Mg of N2O; and

    • (b) an emission credit of 25 Mg of CO2 to offset a deficit of 1 Mg of CH4.

  • Marginal note:Family emission limit

    (4) For the purposes of subsection (3), every vehicle within the fleet or subfleet, as the case may be, must conform to the N2O or CH4 family emission limit corresponding to the emission value determined for B in the formula set out in that subsection.

  • Marginal note:Offsetting deficit

    (5) The deficit calculated under subsection (3) must be offset by using the CO2 emission credits obtained in accordance with sections 34 to 47 for the averaging set in which the fleet is included.

  • Marginal note:No credits

    (6) For greater certainty, the company must not obtain CO2 emission credits with respect to N2O and CH4 emissions for the purpose of participation in the CO2 emission credit system set out in sections 34 to 47.

CO2 Emissions

Marginal note:Average standard
  •  (1) A company must group all its Class 2B and Class 3 heavy-duty vehicles and cab-complete vehicles of the 2014 and subsequent model years — excluding those referred to in the definition vocational vehicle in subsection 1(1) — into a fleet based on model year in accordance with section 18 and must ensure that the fleet average CO2 emission value calculated in accordance with section 23 for that fleet does not exceed the applicable fleet average CO2 emission standard calculated in accordance with section 22 for that fleet for that model year.

  • Marginal note:Offsetting deficit

    (2) When a company incurs a deficit based on the calculation referred to in subsection (1), it must offset the deficit by using the CO2 emission credits obtained in accordance with sections 34 to 47 for the averaging set in which the fleet is included.

Marginal note:Calculation of average standard
  •  (1) Subject to subsection (6), a company must determine the fleet average CO2 emission standard for a given model year, expressed in grams of CO2 per mile and rounded to the nearest 0.1 gram of CO2 per mile, for its fleet of Class 2B and Class 3 heavy-duty vehicles and cab-complete vehicles — excluding those referred to in the definition vocational vehicle in subsection 1(1) — using the formula

    (Σ (A × B)) ÷ C

    where

    A
    is the CO2 emission target value calculated for each vehicle subconfiguration in the fleet using the applicable formula set out in subsection (2) and rounded to the nearest 0.1 gram of CO2 per mile;
    B
    is the number of vehicles of that vehicle subconfiguration in the fleet; and
    C
    is the number of vehicles in the fleet.
  • Marginal note:Vehicle subconfiguration

    (2) Subject to subsection (4), the CO2 emission target value for each vehicle subconfiguration in a fleet must be calculated using the formula set out in one of the following paragraphs, whichever applies:

    • (a) for vehicles equipped with a spark-ignition engine,

      (0.0440 × WF) + 339

      where

      WF
      is the work factor for each vehicle subconfiguration, calculated using the formula set out in subsection (3) and rounded to the nearest pound; or
    • (b) for vehicles equipped with a compression-ignition engine and vehicles that operate without an internal combustion engine,

      (0.0416 × WF) + 320

      where

      WF
      is the work factor for each vehicle subconfiguration, calculated using the formula set out in subsection (3) and rounded to the nearest pound.
  • Marginal note:Work factor

    (3) The work factor for each vehicle subconfiguration is calculated using the formula

    0.75 × (GVWR – curb weight + xwd) + 0.25 × (GCWR – GVWR)

    where

    GVWR
    is the GVWR as defined in subsection 1(1), expressed in pounds;
    curb weight
    is the curb weight as defined in subsection 1(1), expressed in pounds;
    xwd
    is 500 pounds if the vehicle has four-wheel drive or all-wheel drive and is 0 pounds for all other vehicles; and
    GCWR
    is the GCWR as defined in subsection 1(1), expressed in pounds.
  • Marginal note:Alternative target value calculation for 2014 to 2018 model years

    (4) A company may elect to use the CO2 emission target values set out in the table of paragraph (a) or (b), as the case may be, instead of the emission target value calculated in accordance with subsection (2):

  • Marginal note:Election

    (5) If a company elects to use the CO2 emission target values set out in paragraph (4)(a) or (b), the applicable targets continue to apply for all the model years referred to in that paragraph, unless it elects to comply with subsection (2) for the remaining model years.

  • Marginal note:Grouping subconfigurations into configurations

    (6) A company may group vehicle subconfigurations of Class 2B and Class 3 heavy-duty vehicles and cab-complete vehicles — excluding those referred to in the definition vocational vehicle in subsection 1(1) — within a vehicle configuration for the purpose of calculating the fleet average CO2 emission standard if

    • (a) the vehicles of each subconfiguration have the same test weight, GVWR and GCWR, and the work factor and target value are calculated assuming a curb weight equal to two times the test weight minus the GVWR; or

    • (b) the lowest target value of a vehicle subconfiguration is used for all vehicle subconfigurations.
