Commission Implementing Regulation (EU) 2017/1153 of 2 June 2017 setting out a methodology for determining the correlation parameters necessary for reflecting the change in the regulatory test procedure and amending Regulation (EU) No 1014/2010 (Text with EEA relevance)

This Regulation provides for:

1. a methodology for the correlation of the CO2 emissions measured in accordance with Annex XXI to Regulation (EU) 2017/1151 with those determined in accordance with Annex XII to Regulation (EC) No 692/2008;

2. a procedure for applying the methodology referred to in point (a) for the purpose of determining each manufacturer’s average specific emissions of CO2;

3. the amendments to Regulation (EU) No 1014/2010 required for the purpose of adapting the monitoring of CO2 emissions data to reflect the change in emission values.

For the purposes of this Regulation, the following definitions shall apply:

1. ‘NEDC CO2 values’ means the CO2 emissions determined in accordance with Annex I and entered into the certificates of conformity;

2. ‘Measured NEDC CO2 values’ means the CO2 emissions (phases and combined) determined in accordance with Annex XII to Regulation (EC) No 692/2008 by way of physical vehicle tests;

3. ‘WLTP CO2 values’ means the CO2 emissions (combined) determined in accordance with the test procedure set out in Annex XXI to Regulation (EU) 2017/1151;

4. ‘WLTP interpolation family’ means the interpolation family as determined in accordance with point 5.6 of Annex XXI to Regulation (EU) 2017/1151;

5. ‘Correlation tool’ means the simulation model referred to in point 2 of Annex I.

Where the measured NEDC CO2 value of a new passenger car is less than 50 g CO2/km, the manufacturer shall, for the purpose of the application of Article 5a of Regulation (EC) No 443/2009, record that value in the certificate of conformity of the vehicles concerned until 31 December 2022.

With effect from 1 January 2021:

1. the specific emissions of those vehicles shall be calculated in accordance with Article 5a of that Regulation, using the WLTP CO2 values of those vehicles;

2. the 7,5 g CO2/km cap provided for in Article 5a of that Regulation shall be taken into account as follows:

   Capn,r = ( 7,5− SCn2020 7,5 ) Capw = Capn,r · ( SCw2020 × 7,5 SCn2020 )

   Where:

   Capn,r	is the proportion of the remaining cap on NEDC in 2020;
   SCn2020	is the super-credit savings on NEDC in 2020;
   SCw2020	is the super-credit savings on WLTP in 2020;
   Capw	is the remaining super-credit savings cap to be taken into account for the calculation of the average specific emissions in 2021 and 2022.
