AETIS represents 18 EETS providers who are now raising alarms about mounting pressures that risk undermining the service’s viability.

The open letter was addressed to Commissioner Apostolos Tzitzikostas, the newly appointed European commissioner for sustainable transport and tourism, with AETIS underlining the role EETS plays in supporting a seamless, interoperable tolling network across the EU.

EETS currently operates in 16 EU member states, serving 2 million vehicles and facilitating the collection of over €10bn (c.£840m) in toll revenues annually.

Despite its progress, AETIS warned that EETS is facing “serious challenges.” Chief among them are concerns over fair remuneration, regulatory stability, and long-term predictability for EETS providers.

The letter specifically criticises actions by national authorities in Germany and the Czech Republic to reduce provider remuneration, even as operational complexity increases.

Chair, Association of Electronic Toll and Interoperable Service (AETIS), Jean-Marc Chery, said: “EETS has the potential to revolutionise road user charging across Europe, but only if providers are given the regulatory certainty and financial fairness they need to thrive.

“Without urgent action from the European Commission, we risk losing the very momentum that has brought us this far.”
