Heavy-duty Vehicle and Engine Greenhouse Gas Emission Regulations

Version of section 22 from 2018-11-16 to 2024-10-30:


Marginal note:Calculation of average standard

  •  (1) Subject to subsection (6), a company must calculate the fleet average CO2 emission standard for a given model year, expressed in grams of CO2 per mile and rounded to the nearest gram of CO2 per mile, for its fleet of Class 2B and Class 3 heavy-duty vehicles and cab-complete vehicles — excluding those that are vocational vehicles or incomplete vocational vehicles — 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 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 applicable formula set out in one of the following paragraphs:

    • (a) for vehicles that are equipped with a spark-ignition engine, the formula set out in column 2 of the table to this paragraph for the model year set out in column 1, 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 — 2016 to 2018 model years

    (4) For vehicles of the 2016 to 2018 model years, a company may, instead of calculating the CO2 emission target value in accordance with subsection (2), elect to calculate that target value for each of those model years using the formula set out in either of the following paragraphs, whichever applies:

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

      (0.0456 × WF) + 352

      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;
    • (b) for vehicles that are equipped with a compression-ignition engine or that operate without an internal combustion 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.
  • (5) [Repealed, SOR/2018-98, s. 24]

  • 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 that are vocational vehicles or incomplete vocational vehicles — 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.
