The European Mobility Week is the European Commission’s leading campaign to promote sustainable urban mobility. It encourages people to shift towards active travel, public transport, and clean, smart transportation solutions. The event runs annually from 16-22 September, ending with the popular Car-Free Day. This week, local authorities are encouraged to test innovative planning measures, showcase new infrastructure and technologies, monitor air quality, and gather public feedback. With more cities participating each year and significant media attention, the campaign has become a key driver for advancing sustainable urban mobility across Europe and beyond.
