International on-road emissions ratings index launched

0

Independent company AIR has developed a standardized ratings system that shows true vehicle emissions during city use. An A-E color-coded rating is used to highlight the difference between tailpipe emissions.

The AIR Index allows for vehicle comparison based on scientifically robust, on-road vehicle testing according to the latest CWA 17379 methodology. Inspiration for the AIR Index has been NCAP, the independent vehicle-safety rating system.

Nick Molden, co-founder of AIR, added, “In our testing, we have found a number of the newest Euro 6 cars still emit significantly more NOX on the road than in the laboratory test used for their type approval. Our tests also reveal some diesel cars cleaner than petrol ones and some older cars are cleaner than newer ones. 

“Change is already underway for new diesel cars and we believe the AIR Index can accelerate that change with car makers and policy makers aligned to changing our cities’ air quality – for the better.”

AIR hopes that its new system will inform car buyers and city policy makers with independent information regarding vehicle emissions.

Massimo Fedeli, co-founder and operations director, AIR, said, “The AIR Index is a game-changer. It compiles the results of the most independent, consistent and thorough tests ever carried out. We have worked hard over the last year with our expert academic and industry group to deliver European standardization for the AIR Index through the CEN Workshop Agreement. 

“For the first time there are comparative ratings between vehicles as a result of setting tough but fair testing criteria, all conducted on the road, in real driving conditions. The same standardized test is applied to each different car type.”
