Heavy-duty Vehicle and Engine Greenhouse Gas Emission Regulations

Marginal note:Calculation of average standard

• 22 (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):

  • (a) for the 2014 to 2017 model years,

    	Column 1	Column 2	Column 3
    Item	Model Year	Engine Cycle	Alternate CO2 Emission Target (grams/mile)
    1	2014	Spark-ignition engine	(0.0482 × WF) + 371
    		Compression-ignition engine	(0.0478 × WF) + 368
    2	2015	Spark-ignition engine	(0.0479 × WF) + 369
    		Compression-ignition engine	(0.0474 × WF) + 366
    3	2016	Spark-ignition engine	(0.0469 × WF) + 362
    		Compression-ignition engine	(0.0460 × WF) + 354
    4	2017	Spark-ignition engine	(0.0460 × WF) + 354
    		Compression-ignition engine	(0.0445 × WF) + 343

  • (b) for the 2014 to 2018 model years,

    	Column 1	Column 2	Column 3
    Item	Model Year	Engine Cycle	Alternate CO2 Emission Target (grams/mile)
    1	2014	Spark-ignition engine	(0.0482 × WF) + 371
    		Compression-ignition engine	(0.0478 × WF) + 368
    2	2015	Spark-ignition engine	(0.0479 × WF) + 369
    		Compression-ignition engine	(0.0474 × WF) + 366
    3	2016 to 2018	Spark-ignition engine	(0.0456 × WF) + 352
    		Compression-ignition engine	(0.0440 × WF) + 339

• 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.
