On 4 March 2021, the Commission adopted a new implementing regulation requiring all new vehicles in the EU to be equipped with a device that records fuel consumption. The data will be collected by manufacturers when vehicles are brought in for repair and by authorities when vehicles are occasionally subject to special assessments. This information will be collected from new vehicles sold from March 2021 and reported to the European Environment Agency (EEA) from April 2022.
According to the text of the regulation, "monitoring and reporting of data on passenger cars and light commercial vehicles registered in the Union are essential for the functioning of the CO2 emission performance standards set out in Regulation (EU) 2019/631." This collected data will allow the monitoring of the gap between the approval through a certificate of conformity (EC Whole Vehicle Type Approval, ECWVTA), by the national competent authority and the actual CO2 emissions. The data will also allow a better assessment of vehicle performance under real driving conditions, helping to ensure that CO2 emission reduction targets remain achievable. The collection of live data is the first implementing measure adopted under the CO2 emissions standards, which come into force on 1 January 2020. The installation of on-board devices is optional for low-volume manufacturers. Based on the General Data Protection Regulation (GDPR), the Commission, EU member states and also car manufacturers must guarantee that appropriate standards are met and vehicle owners have the possibility to object to the collection of data. The aggregated data will be published annually by the Commission from December 2022 onwards to illustrate, among other things, the difference between the former WLTP procedure and the real CO2 emissions for each manufacturer's new vehicle fleet.
