On 31 May 2017, the European Commission published its proposal to review the ‘Eurovignette’ Directive. The Directive defines how Member States of the European Union can charge vehicles for their use of road infrastructure and was conceived to ensure the proper functioning of the EU transport market. Transport accounts for around a quarter of EU GHG emissions. Meanwhile air pollution from road transport contributes to over 400,000 premature deaths per year, 26,000 people die in traffic annually, and the EU economy loses €100 bn every year in congestion. This briefing outlines why road charging is a key instrument to tackle this.
