            COMMISSION IMPLEMENTING REGULATION (EU) 2018/1003
of 16 July 2018
         
amending Implementing Regulation (EU) 2017/1152 to clarify and simplify the correlation procedure and to adapt it to changes to Regulation (EU) 2017/1151
(Text with EEA relevance)


THE EUROPEAN COMMISSION,

Having regard to the Treaty on the Functioning of the European Union,


Having regard to Regulation (EU) No 510/2011 of the European Parliament and of the Council of 11 May 2011 setting emission performance standards for new light commercial vehicles as part of the Union's integrated approach to reduce CO2 emissions from light duty vehicles (1), and in particular the third subparagraph of Article 13(6) thereof,

Whereas:







(1)


Based on the experience gained from the implementation of Commission Regulation (EU) 2017/1151 (2) and Commission Implementing Regulation (EU) 2017/1152 (3), it has become evident that certain elements of the latter Regulation should be amended.












(2)


It is necessary to complement the existing method for defining the end-points of the interpolation line used for calculating the NEDC CO2 emission value of an individual vehicle. Those end-points, which are represented by a test vehicle with the highest CO2 emission values, and test vehicle with the lowest values, should be defined so that the difference between the two test vehicles high and low is equal to or higher than 5 g CO2/km.












(3)


In order to avoid that the CO2 emission values of individual vehicles are determined on the basis of interpolation lines that do not provide the minimum difference, it is appropriate that this amendment enters into force without delay.












(4)


Where for the purpose of type approval under Regulation (EU) 2017/1151, road load matrix families are used, the calculation of the NEDC CO2 emission value of an individual vehicle belonging to such a family should be simplified by deriving the road load coefficients to be used for the calculation of the NEDC CO2 value from the road load coefficients of the individual vehicle as determined under Regulation (EU) 2017/1151.












(5)


As regards incomplete N1 vehicles, the amendment to Annex XII to Regulation (EU) 2017/1151 should be taken into account for the purpose of the determination of the road load coefficients to be used as input to the correlation tool.












(6)


In order to ensure a robust correlation output, it is appropriate to add the number of cylinders as an input to be provided for the correlation tool.












(7)


The opportunity should also be taken to correct some editorial errors in the text.












(8)


The measures provided for in this Regulation are in accordance with the opinion of the Climate Change Committee,





HAS ADOPTED THIS REGULATION:



Article 1
Annex I to Implementing Regulation (EU) 2017/1152 is amended in accordance with the Annex to this Regulation


Article 2
This Regulation shall enter into force on the seventh day following that of its publication in the Official Journal of the European Union.




This Regulation shall be binding in its entirety and directly applicable in all Member States.
Done at Brussels, 16 July 2018.

Notwithstanding point (a), where the cycle energy demand of the WLTP vehicle H and/or L, as determined in accordance with paragraph 5 of Sub-Annex 7 to Annex XXI to Regulation (EU) 2017/1151, does not result in the highest, or respectively, the lowest cycle energy demand for the NEDC vehicle H and/or L, the NEDC road load coefficients shall be determined in accordance with either of the following:






(i)


on the basis of the individual vehicle in the interpolation family with the highest, or respectively, the lowest NEDC cycle energy demand;
