The mobility projections in this Transport Outlook indicate that global passenger transport volumes in 2050 could be up to 2.5 times as large as in 2010, and freight volumes could grow by a factor of four. Emissions of CO2 grow more slowly because of increasing energy efficiency, but may nevertheless more than double.

The world’s population will reach 9 billion by 2050. Meeting their
transport demands will be challenging. As both population and
incomes rise, global passenger mobility and global freight transport
volumes may triple by 2050. The International Transport Forum’s

The Organisation for Economic Co-operation and Development’s (OECD) International Transport Forum (ITF) has published a discussion paper titled “Key Mobility Challenges in Indian Cities,” which identifies challenges in urban mobility in India under three sections: urbanization and transport; urban mobility challenges; and current policies and interventions.

This report provides a brief update of greenhouse gas emission trends from the transport sector and discusses the outcome of the United Nations Conference of the Parties to the Framework Convention on Climate Change held in December 2009 in Copenhagen.

This document says that climate change poses two fundamental challenges for the transport sector: transport will have to significantly reduce greenhouse gas (GHG) emissions and it will require investment in order to adapt to impacts of climate change.
