The ITF Transport Outlook 2023 examines the impacts of different policy measures on global transport demand and carbon dioxide (CO₂) emissions to 2050. The analysis covers the movement of passengers and freight across all transport modes. A particular focus is placed on transport policies that make cities more liveable. A second focus is on infrastructure investment decisions and what different policy scenarios mean for them. As a third focus, the report explores regional differences in policy impacts.

The analysis is based on two distinct scenarios for the future of transport, simulated with the ITF’s in-house transport models. The Current Ambition scenario assumes policies to decarbonise transport continue along their current pathway and considers the implications for transport demand, CO₂ emissions and further aspects over the next three decades. The High Ambition scenario assumes policies focused on accelerating the decarbonisation of the transport sector and their impact.
