# Heavy-duty Vehicle and Engine Greenhouse Gas Emission Regulations

Version of section 22 from 2013-02-22 to 2018-11-15:
﻿

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):

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

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

• 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.
