         COMMISSION IMPLEMENTING DECISION (EU) 2020/1222
         of 24 August 2020
         on the approval of efficient vehicle exterior lighting using light emitting diodes as an innovative technology for reducing CO2 emissions from internal combustion engine powered light commercial vehicles with regard to NEDC conditions pursuant to Regulation (EU) 2019/631 of the European Parliament and of the Council
         (Text with EEA relevance)
         THE EUROPEAN COMMISSION,
         Having regard to the Treaty on the Functioning of the European Union,
         Having regard to Regulation (EU) 2019/631 of the European Parliament and of the Council of 17 April 2019 setting CO2 emission performance standards for new passenger cars and for new light commercial vehicles, and repealing Regulations (EC) No 443/2009 and (EU) No 510/2011 (1), and in particular Article 11(4) thereof,
         Whereas:
         
                     (1)
                  
                  
                     On 19 December 2019, the manufacturers Toyota Motor Europe, Opel Automobile GmbH–PSA, FCA Italy S.p.A., Automobiles Citroën, Automobiles Peugeot, PSA Automobiles SA, Audi AG, Ford-Werke GmbH, Jaguar Land Rover Ltd., Hyundai Motor Europe Technical Center GmbH, Škoda Auto a.s., BMW AG, Renault SA, Honda Motor Europe Ltd, Volkswagen AG and Volkswagen AG Nutzfahrzeuge submitted a joint application (‘the application’) for the approval, in accordance with Article 11 of Regulation (EU) 2019/631, of efficient vehicle exterior lighting using light emitting diodes (‘efficient exterior LED light’) as an innovative technology for reducing CO2 emissions from internal combustion engine powered light commercial vehicles capable of running on petrol, diesel and certain alternative fuels.
                  
               
                     (2)
                  
                  
                     The application has been assessed in accordance with Article 11 of Regulation (EU) 2019/631, Commission Implementing Regulation (EU) No 427/2014 (2) as well as with the Technical Guidelines for the preparation of applications for the approval of innovative technologies pursuant to Regulation (EC) No 443/2009 of the European Parliament and of the Council (3) (July 2018 version) (4). In accordance with Article 11(3) of Regulation (EU) 2019/631, the application was accompanied by a verification report undertaken by an independent and certified body.
                  
               
                     (3)
                  
                  
                     The application refers to CO2 emission savings that cannot be demonstrated by measurements performed in accordance with the New European Driving Cycle (‘NEDC test’) set out in Commission Regulation (EC) No 692/2008 (5).
                  
               
                     (4)
                  
                  
                     The use of light emitting diodes for improving the efficiency of exterior vehicle lighting has already been approved for certain exterior lights of passenger cars by Commission Implementing Decisions 2014/128/EU (6), (EU) 2015/206 (7), (EU) 2016/160 (8) and (EU) 2016/587 (9) (jointly referred to as ‘past approval Implementing Decisions’) as an innovative technology capable of reducing CO2 emissions in a way that is not covered by the measurements performed as part of the NEDC test.
                  
               
                     (5)
                  
                  
                     Based on the experience gained from the assessment of the applications in the framework of the past approval Implementing Decisions as well as on the reports and information provided with the application, it has been satisfactorily and conclusively demonstrated that an efficient exterior LED light or appropriate combinations thereof meet the eligibility criteria referred to in Article 11 of Regulation (EU) 2019/631 and Implementing Regulation (EU) No 427/2014 and provide a reduction in CO2 emissions of at least 1 g CO2/km as compared to the same set of baseline exterior lights.
                  
               
                     (6)
                  
                  
                     In addition to the exterior vehicle lighting for which the use of efficient LED lights has already been approved in the past approval Implementing Decisions, the application also refers to the use of efficient exterior LED lights in cornering, static bending, end-outline marker and side marker lights. As those lights are not turned on during the measurements performed as part of the NEDC test, it is appropriate to approve the use of efficient exterior LED lights also in those lights.
                  
               
                     (7)
                  
                  
                     The application sets out a methodology for determining the CO2 savings from the use of efficient exterior LED lights in a range of vehicle lights for use in light commercial vehicles powered by internal combustion engines capable of running on petrol, diesel, liquefied petroleum gas (LPG), compressed natural gas (CNG) or E85.
                  
               
                     (8)
                  
                  
                     In view of the limited availability of E85 on the Union market as a whole, it is not considered justified to distinguish this fuel from petrol for the purpose of the testing methodology.
                  
               
                     (9)
                  
                  
                     The applicants have provided studies supporting that the usage patterns of light commercial vehicles and those of passenger cars, with regard to the use of exterior vehicle lighting, are sufficiently similar to allow the same methodology to be applied for light commercial vehicles as the one set out in the past Implementing Decisions.
                  
               
                     (10)
                  
                  
                     However, with regard to the cornering lamps, the static bending lamps, end-outline marker lights and side marker lights, which have not been covered by the past Implementing Decisions, the applicants have proposed to include specific usage factors and power consumption values in the testing methodology. As the usage factors and power consumption values proposed by the applicants for those lights result in values that can be considered conservative, it is appropriate to add those factors and values to the testing methodology.
                  
               
                     (11)
                  
                  
                     The methodology should also be complemented to ensure that the presence of adaptive front lighting systems (AFS) used in low beam lights can be taken into account.
                  
               
                     (12)
                  
                  
                     Taking into account those additions, the testing methodology should be considered appropriate for determining the CO2 savings from the use of the innovative technology in light commercial vehicles.
                  
               
                     (13)
                  
                  
                     Manufacturers should have the possibility to apply to a type-approval authority for the certification of CO2 savings from the use of efficient exterior LED lights where the conditions laid down in this Decision are met. Manufacturers should for that purpose ensure that the application for certification is accompanied by a verification report from an independent and certified body confirming that the innovative technology complies with the conditions laid down in this Decision and that the savings have been determined in accordance with the testing methodology set out in the Annex of this Decision.
                  
               
                     (14)
                  
                  
                     In order to facilitate a wider deployment of the innovative technology in new vehicles, a manufacturer should also have the possibility to submit a single application for the certification of the CO2 savings from several efficient exterior LED lights by a single certification application. It is, however, appropriate to ensure that where this possibility is used a mechanism is applied that incentivises the deployment of only those efficient exterior LED lights that offer the highest efficiency.
                  
               
                     (15)
                  
                  
                     It is the responsibility of the type-approval authority to verify thoroughly that the conditions for certifying the CO2 savings from the use of an innovative technology as specified in this Decision are met. Where the certification is granted, the responsible type-approval authority should ensure that all elements considered for the certification are recorded in a test report and kept together with the verification report and that this information is made available to the Commission on request.
                  
               
                     (16)
                  
                  
                     For the purpose of determining the general eco-innovation code to be used in the relevant type-approval documents in accordance with Annexes I, VIII and IX to Directive 2007/46/EC of the European Parliament and of the Council (10), it is necessary to attribute an individual code to the innovative technology.
                  
               
                     (17)
                  
                  
                     From 2021, manufacturers’ compliance with their specific CO2 emission targets is to be established on the basis of the CO2 emissions determined in accordance with the Worldwide Harmonised Light Vehicle Test Procedure (WLTP) set out in Commission Regulation (EU) 2017/1151 (11). CO2 savings from the innovative technology certified by reference to this Decision may therefore be taken into account for the calculation of manufacturers’ average specific CO2 emissions only for the calendar year 2020,
                  
               HAS ADOPTED THIS DECISION:

               Methodology to determine the CO2 savings of Efficient Exterior LED Lighting under NEDC for use in light commercial vehicles
            
            1.   INTRODUCTION
            This Annex sets out the methodology to determine the CO2 (carbon dioxide) emission savings to be attributed to the use of efficient vehicle exterior lighting using one or an appropriate combination of LED lights listed in Article 1, for use in light commercial N1 vehicles powered by an internal combustion engine.
            2.   TESTING CONDITIONS
            The testing conditions shall fulfil the requirements of UN/ECE Regulations Nos 4 (1), 6 (2), 7 (3), 19 (4), 23 (5), 38 (6), 48 (7), 91 (8) 100 (9), 112 (10), 119 (11) and 123 (12) (1). The power consumption shall be determined in accordance with point 6.1.4 of UN/ECE Regulation No 112, and points 3.2.1 and 3.2.2 of Annex 10 to that Regulation.
            For the low beam adaptive front lighting system (AFS) falling within at least two of the Classes C, E, V or W as defined in Regulation UN/ECE No 123 (see Table 1), the power consumption measurements shall be done at the LED intensity of each class (Pk), where k corresponds to each class specified at Table 1 as defined in Regulation UN/ECE 123.
            If it is agreed with the technical service that Class C is the representative/average LED intensity for the vehicle application, power consumption measurements shall be done in the same way as for any other exterior LED light included in the combination.

            For each efficient exterior LED light included in a combination, the measurement of the current shall be performed at a voltage of 13,2 V. LED module(s) operated by an electronic light source control gear, shall be measured as specified by the applicant.
            The manufacturer may request that additional measurements of the current shall be performed at other voltages, where the necessity to do so can be demonstrated on the basis of verified documentation.
            In any case the measurements (n) shall be performed for each voltage at least five times consecutively. The applied voltage and the measured current shall be recorded in four decimals.
            The power consumption shall be determined by multiplying the voltage with the measured current. The average of the power consumption for each efficient exterior LED light () [W] shall be calculated as set out in Formula 1 with four decimals to be taken into account in the calculations. When a stepper motor or electronic controller is used for the supply of the electricity to the LED lamps, then the electric load of this component is to be excluded from the measurement.

                  5.   ROUNDING
            The CO2 savings () and the uncertainty of the CO2 savings () shall be rounded to two decimal places.
            Each value used in the calculation of the CO2 savings shall either be applied unrounded or be rounded to the minimum number of decimal places which allows the maximum total impact (i.e. combined impact of all rounded values) on the savings to be lower than 0,25 [g CO2/km].
            6.   CHECK AGAINST THE MINIMUM CO2 SAVINGS THRESHOLD
            The type-approval authority shall ensure for each type, variant and version of a vehicle fitted with the efficient exterior LED lights that the minimum threshold criterion as specified in Article 9(1)(a) of Implementing Regulation (EU) No 427/2014 is met.
            When verifying whether the minimum threshold criterion is met, the type-approval authority shall take into account, in accordance with Formula 9, the CO2 savings determined in point 3 and the uncertainty determined in point 4.
            
               Formula 9
            
            
               
            where,
            
                        MT
                     
                     
                        is the minimum threshold equal to 1 g CO2/km
                     
                  
                        
                           
                     
                     
                        is the CO2 savings [g CO2/km] as defined in point 3
                     
                  
                        
                           
                     
                     
                        is the uncertainty of the CO2 savings calculated in accordance with point 4 [g CO2/km].
                     
                  7.   CERTIFICATION OF THE CO2 SAVINGS
            The type approval authority is to certify the CO2 savings in accordance with point 3 based on measurements of the LED Lighting system and the baseline halogen lamps using the test methodology set out in this Annex. Where the CO2 emission savings are below the threshold specified in Article 9(1) of Implementing Regulation (EU) No 427/2014, the second subparagraph of Article 11(2) of that Regulation shall apply.
