ABSTRACT
A simple definition of sustainable mobility is “traveling with the least possible impact upon the planet”. This suggests a hierarchy of preferable transport, from fuel-free “active” walking and cycling, down to private jet-flying or superyacht sailing. The “sustainable mobility paradigm” is more specifically related to policymaking and priorities and closely reflects the “A-S-I” hierarchy in recent sustainability studies: Avoid (travel demand and car ownership); Shift (travel to the most sustainable modes); Improve (efficiency of individual modes). Addressing the impacts of car driving and flying is now viewed as a particularly key concern.
