Passenger Automobile and Light Truck Greenhouse Gas Emission Regulations

Marginal note:Allowance for reduction of air conditioning refrigerant leakage

• 18.2 (1) A company may elect to calculate, using the following formula, an allowance for the use, in its fleet of passenger automobiles or light trucks, of air conditioning systems that incorporate technologies designed to reduce air conditioning refrigerant leakage:

  (Σ (A × B)) ÷ C

  where

  A

  is the CO₂ equivalent leakage reduction for each air conditioning system in the fleet that incorporates those technologies, determined in accordance with section 1867 of Title 40, chapter I, subchapter C, part 86, of the CFR and expressed in grams of CO₂ equivalent per mile;

  B

  is the number of passenger automobiles or light trucks in the fleet that are equipped with the air conditioning system; and

  C

  is the total number of passenger automobiles or light trucks in the fleet.

• Marginal note:Allowance for improvement of air conditioning system efficiency

  (2) A company may elect to calculate, using the following formula, an allowance for the use, in its fleet of passenger automobiles or light trucks, of air conditioning systems that incorporate technologies designed to reduce air-conditioning-related CO₂ emissions by improving air conditioning system efficiency:

  (Σ (A × B)) ÷ C

  where

  A

  is the air conditioning efficiency allowance for each air conditioning system in the fleet that incorporates those technologies, determined in accordance with the provisions relating to credits in section 1868 of Title 40, chapter I, subchapter C, part 86, of the CFR and expressed in grams of CO₂ per mile;

  B

  is the number of passenger automobiles or light trucks in the fleet that are equipped with the air conditioning system; and

  C

  is the total number of passenger automobiles or light trucks in the fleet.
