Approval authorities and technical services should therefore, together with manufacturers, strive to ensure that WLTP and NEDC tests that are carried out for the purpose of this Regulation are performed under test conditions that are comparable and coherent with the objective of this Regulation.\n(3)\nFor that purpose, it is necessary to clarify certain aspects of the WLTP test conditions that should apply for the correlations performed in view of providing WLTP and NEDC monitoring CO2 emissions data for vehicles newly registered in 2020. Those clarifications should apply without prejudice to the procedure and requirements set out in Commission Regulation (EU) 2017/1151 and without affecting the validity of any type approvals granted on that basis.\n(4)\nIt is also necessary to determine the difference in 2020 between CO2 emission values declared by the manufacturers for the purpose of the emissions type approval and those measured pursuant to Regulation (EU) 2017/1151. Manufacturers should therefore be required to calculate and report to the Commission the WLTP CO2 emission values for all new passenger cars registered in the calendar year 2020 using the measurement values for vehicle H and L as input to the interpolation method.\n(5)\nFor a limited number of interpolation families, only vehicle H measurement values will be available in 2020. The number of those families should be closely monitored and the Commission should consider excluding those families from the calculation of the 2020 reference data, should there be a significant increase in the number of such families as compared to the 2018 situation.\n(6)\nThe transparency in the emissions testing should be improved, and data on the WLTP tests as well as on the correlation results should therefore be made available to the Commission. This will allow the Commission to swiftly identify and address issues and possible inconsistencies relating to the implementation of the procedures. For that reason, the input data matrix should be completed for each WLTP test performed and be transmitted to the Commission in its entirety as part of the correlation tool data exchange. To ensure confidentiality, the input data file should be encrypted in view of the transmission.\n(7)\nThe measures provided for in this Regulation are in accordance with the opinion of the Climate Change Committee,\nHAS ADOPTED THIS REGULATION:",
