TÜV Austria has certified two of Kapsch TrafficCom's on-board units: the TRP-4010 and OBU-5310.
Kapsch suggests this means that the products are the smallest, lightest and most sustainable in their class.
The two products are also the first electronic tolling solution elements to align with the EU taxonomy regulation on climate change, the company says.
TÜV Austria, part of the TÜV network of independent technical inspection associations, has validated that the calculations and associated reports of the two products' carbon footprints meet the requirements outlined in the EN ISO 14067:2018 standard.
The TÜV certification considered the carbon footprint associated with every stage of the product lifecycle, including raw material sourcing, design, production, transportation, use and end-of-life management.
