A visualisation of cars tested for the EQUA Aq Index, split by Euro standard and fuel type, showing progress towards reduction of NOx emissions.
A Portable Emissions Measurement System (PEMS) is used to measure vehicle emissions on the road rather than in the laboratory. This methodology, soon to be included as part of the official test for new cars, is used by Emissions Analytics to build a detailed database of real-world emissions. Data from over 1000 real-world vehicle tests is available via subscription. Contact us for further details
