Check the AIR Index now and find out if your car is part of the problem or the solution for air quality in our towns and cities.
The AIR Index helps car buyers and policy makers make informed choices using the results of independent, on-road emission tests.
The AIR Index has been established by the not-for-profit organisation AIR (Allow Independent Road-testing), a global alliance of scientists, regulatory experts and organisations committed to reducing harmful vehicle emissions and improving air quality, now.
The AIR Index offers a complete solution to address urban air quality by providing trusted information through vehicle ratings or urban NOx emissions. A full suite of marketing and communication material is available for point of sale locations, along with a single vehicle labelling approach and dataset to enable pan-European city access through fair and effective mobility policies.
Each car is independently tested in accordance with a voluntary standardised European protocol CWA 17379. This approach allowed the practical experience gained from over six years of commercial on-road testing by Emissions Analytics to be combined with expertise from a wide range of leaders in emissions control, emissions policy and air quality.
The resulting standardised method can be used by any test centre to collect comparative emissions data, which can then be fed into the AIR Index ratings system. Every AIR Index rating requires at least two cars of the same type to be tested at least three times, recording at least five x 10km trips, which each take approximately 20 minutes and in full compliance with the boundary conditions specified in the protocol.
