The 2015 ITF Transport Outlook examines the trends and forecasts the development of global transport volumes and related CO2 emissions and health impacts through to 2050. It examines factors that can affect supply and demand for transport services and focuses on scenarios illustrating potential upper and lower pathways depending on the transport and CO2 intensity of the future growth and particularly urban transport policies. The analysis highlights the consequences of rapid urbanisation outside the OECD on overall transport volumes, CO2 emissions and health impacts. The ITF Transport Outlook also assesses how the shifting global economic centre of gravity from developed economies towards emerging economies affects production and consumption patterns – and therefore also international trade-related freight transport.
