In the course of the past few years interest in sustainable mobility has risen considerably. The field's scope has expanded to include smart cities, hybrid cars, car sharing systems and alternative means of transportation such as bicycles and public transport. Along with reducing greenhouse gas emissions, noise pollution and traffic, such means of transportation play an important role in maintaining physical and mental wellbeing.
In Europe, this theme has become of foundational importance as, according to the European Commission, it is in cities themselves that the central challenge of sustainability is played out. By reducing, rethinking and innovating means of transportation, European cities can improve their energy consumption and the environmental performance of transportation, as well as making citizens' lives healthier and safer.
In Italy, the term was introduced at the end of the '90s following the promulgation of the Environment Ministry's Decree "Sustainable Mobility in Urban Areas" in March 1998, better known as the "Ronchi Decree". Sustainable mobility means choosing efficient and environmentally friendly means of transportation, which transform established habits in favour of innovative tools and solutions.
