(1)

A new regulatory test procedure for measuring CO2 emissions and fuel consumption from light duty vehicles, the World Harmonised Light Vehicles Test Procedure (WLTP), set out in Commission Regulation (EU) 2017/1151 (2), will replace the New European Test Cycle (NEDC), which is currently used pursuant to Commission Regulation (EC) No 692/2008 (3), with effect starting from 1 September 2017. The WLTP is expected to provide CO2 emission and fuel consumption values that are more representative of real driving conditions.

(2)

In order to take into account the difference in the level of CO2 emissions measured under the existing NEDC and the new WLTP procedures, a methodology for correlating those values has been put in place pursuant to Commission Implementing Regulation (EU) 2017/1153 (4).

(3)

The correlation methodology is to be used during the phasing-in of the WLTP until end of 2020 to ensure that manufacturers' compliance with the CO2 emission targets can be verified on the basis of the NEDC emission values during that period. As a consequence, WLTP based specific CO2 emission targets should be applied with effect from the calendar year 2021.

(4)

In 2020 the CO2 emissions of all new vehicles registered is to be determined on the basis of both the NEDC and the WLTP in accordance with the correlation methodology. By monitoring both those CO2 values, robust datasets should be available for comparing the level of emissions resulting from the two test procedures. Those datasets should allow for the determination of WLTP based specific emission targets that are of a stringency comparable to those determined by reference to NEDC measurements in accordance with the requirement set out in Article 13(6) of Regulation (EU) No 510/2011.

(5)

For the purpose of setting a manufacturer's specific emission target in 2021, the average WLTP CO2 emissions of the new light commercial vehicles registered in 2020 should be used as reference value. The specific emission target should be determined by either increasing or decreasing that reference value proportionally to the manufacturer's performance in meeting its NEDC based target in 2020.

(6)

In order to ensure that the WLTP based specific emission targets remain comparable over time, account should be taken of annual changes in the average mass of the manufacturer's fleet.

(7)

A number of new parameters should be added to the detailed data that is to be monitored following the introduction of the WLTP. Under the WLTP the CO2 emission values are to be calculated taking into account the specific configuration of each individual vehicle. In order to ensure that the vehicles can be identified and the data effectively verified by manufacturers as well as by the Commission, it is appropriate to base the monitoring on vehicle identification numbers.

(8)

Annexes I and II to Regulation (EU) No 510/2011 should therefore be amended accordingly,
