Sustainable Transport
Definition
Sustainable transport provides safe, affordable and accessible mobility while minimising emissions, pollution, land take, congestion and road danger. The strategy hierarchy is avoid-shift-improve: avoid unnecessary trips (land use, telepresence), shift to efficient modes (walking, cycling, public transport, rail freight), and improve remaining vehicles (electrification, efficiency, clean fuels). Transport generates around a fifth of global CO₂ and is among the slowest sectors to decarbonise.

Overview
How it is used
The concept structures national and city transport strategies, the avoid-shift-improve framework, SLOCAT partnership work and SDG 11. 2 monitoring.
Why it matters
Transport is the hardest major sector to clean because it is the most behavioural; sustainable transport is the whole-system answer.
