Heavy-duty Vehicle and Engine Greenhouse Gas Emission Regulations

Marginal note:Calculation of average standard

• 22 (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;

    	Column 1	Column 2
    Item	Model Year	CO2 Emission Target (grams/mile)
    1	2014	(0.0482 × WF) + 371
    2	2015	(0.0479 × WF) + 369
    3	2016	(0.0469 × WF) + 362
    4	2017	(0.0460 × WF) + 354
    5	2018 to 2020	(0.0440 × WF) + 339
    6	2021	(0.0429 × WF) + 331
    7	2022	(0.0418 × WF) + 322
    8	2023	(0.0408 × WF) + 314
    9	2024	(0.0398 × WF) + 306
    10	2025	(0.0388 × WF) + 299
    11	2026	(0.0378 × WF) + 291
    12	2027 and subsequent	(0.0369 × WF) + 284

  • (b) for vehicles that are equipped with a compression-ignition engine or that operate without an internal combustion 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.

    	Column 1	Column 2
    Item	Model Year	CO2 Emission Target (grams/mile)
    1	2014	(0.0478 × WF) + 368
    2	2015	(0.0474 × WF) + 366
    3	2016	(0.0460 × WF) + 354
    4	2017	(0.0445 × WF) + 343
    5	2018 to 2020	(0.0416 × WF) + 320
    6	2021	(0.0406 × WF) + 312

    10	2025	(0.0367 × WF) + 282
    11	2026	(0.0357 × WF) + 275
    12	2027 and subsequent	(0.0348 × WF) + 268

• 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.
