Collection of actual fuel consumption data

Through the statistics that are collected, the EU aims to identify differences between the vehicles' real-world fuel consumption and corresponding information about the vehicles' consumption in type approvals, and how this develops over time. This is a form of market supervision of car manufacturers’ compliance with requirements. The European Commission is doing this to investigate to what extent manufacturers are achieving their reduction targets and also to share information about their findings.

Manufacturers are required to achieve various targets for reducing CO2 emissions set for new passenger cars and light commercial vehicles registered in Europe. The European Commission is therefore dependent on statistical data on actual fuel consumption through the surveillance and reporting of data from new passenger cars and light commercial vehicles in order to be able to keep track of how manufacturers are doing when it comes to achieving their reduction targets.

Every year, the EU will publish anonymised and compiled data sets per car manufacturer.

The collection of OBFCM data at mandatory roadworthiness tests is stipulated in Regulation (EU) 2021/392.

The workshops, their suppliers of diagnostic equipment and the data transfer agents involved can only store OBFCM data until these have been submitted to and received by the Norwegian Public Roads Administration (NPRA). The workshops and suppliers involved cannot use the data for other purposes. This means that when the data have been sent to and received by the NPPRA, they must be deleted by the workshop and their suppliers.

If you as the car owner or the person who presented the car for the mandatory roadworthiness test want to see the OBFCM data that have been read out from the car, the data may be displayed for example on the invoice for the roadworthiness test.

The NPRA can only store OBFCM data until they have been reported to the European Commission. The NPRA processes OBFCM data in accordance with our privacy statement.

The European Commission can store the data for up to 20 years, for statistical purposes. Their purpose for the statistics is to follow up the car manufacturers and the differences between the cars' real-world fuel consumption and the corresponding type approval values over time.
