The document defines sustainable transportation as a system that meets citizens' needs in a way that satisfies humans and the ecosystem, while promoting fairness between generations. Sustainable transportation limits environmental waste within the planet's capacity, uses renewable resources sustainably, and aims to create efficient mobility for communities through policies, systems, and technologies. Currently, transportation accounts for 20-25% of global energy use and carbon emissions. The history of transportation development includes innovations like the passenger train and bicycle, while oil price drops in the 1980s-90s increased individual vehicle ownership and suburban development patterns requiring car dependency.
