Light-duty vehicle exhaust emissions – On-road testing data in support to Euro 7 regulation

Data description: this dataset contains the results of 445 vehicle exhaust emissions tests conducted by various European laboratories in support of the development of the Euro 7 regulation for light-duty vehicles. All the tests were performed on the road with a Portable Emissions Measurement System (PEMS). The dataset contains details regarding the tested vehicle, the characteristics of the emission test, and the gaseous and particulate emissions measured. The tests were conducted in eight European countries between November 2019 and January 2022.
Source of the data: certain tests were conducted on aged Euro 6b and Euro 6c (and few Euro 6d-TEMP) vehicles (with a mileage 100 000 km to 500 000 km) and focused on the durability of emissions control systems. The corresponding publication where the data on aged vehicles is discussed is Technical studies for the development of Euro 7 : durability of light-duty vehicle emissions, Publications Office of the European Union, 2022, https://data.europa.eu/doi/10.2873/40588. For these vehicles, the emission limits of the Real Driving Emissions Regulation (RDE) are not applicable. On the other hand, other tests were performed on more modern vehicles meeting the Euro 6d-TEMP and Euro 6d standards. The type-approval of these vehicles required to meet the emission limits set in the RDE regulation for on-road testing. The testing of these vehicles was the basis to assess the performance within the boundaries of the RDE test and beyond. The outcome of the analysis are summarised in Technical studies for the development of Euro 7 : testing, pollutants and emission limits, Publications Office of the European Union, 2022, https://data.europa.eu/doi/10.2873/97170 and the corresponding annexes (doi: 10.2873/32056).
The JRC data corresponds to PEMS tests performed in Northern Italy in support of the CLOVE consortium, contractor of DG GROW.
The laboratories provided to the JRC the data exchange file of the PEMS test and certificate of conformity of each vehicle. The JRC assessed the trip validity and calculated emissions using the in-house EMROAD tool (version ranging from EMROAD 6.04_B1 to EMROAD 6.05_B2).
