Article 7 U.K.Determination and correction of NEDC CO₂ values for the calculation of the specific average emissions

1. Starting from the calendar year 2017 until 2020 inclusive, the average specific CO₂ emissions of a manufacturer shall be calculated using the NEDC CO₂ values determined in accordance with the procedure laid down in Section 4 of Annex I, unless paragraph (1)(b) or (c) or paragraph (2) of Article 3 applies.

2. Where for a WLTP interpolation family the deviation factor De, determined in accordance with point 3.2.8 of Annex I, exceeds the value 0,04, or in the presence of a verification factor ‘1’ as determined in that point, the average specific NEDC CO₂ emissions of the manufacturer responsible for that interpolation family shall be multiplied by the following correction factor:

Where:

De_i

is the value determined in accordance with point 3.2.8 of Annex I;

r_i

is the number of annual registrations of vehicles belonging to the respective WLTP interpolation family i concerned;

δ_з,i

is equal to 0 if De_i is missing and equal to 1 otherwise;

N

is the number of WLTP interpolation families for which a manufacturer is responsible.
