Transportation
Sustainability Research Trends, Themes, and Gaps
"Sustainable transportation is generally considered to include provision of safe, effective, and efficient access and mobility now and in the future while considering the long-term economic, social, and environmental needs of society. Potential research projects may address themes such as:
- Further defining sustainability in the context of transportation systems.
- Implementation strategies for achieving transportation sustainability
- Approaches for measuring performance in achieving sustainability"
Climate Forcings from the Transport Sectors
"Although the transport sector is responsible for a large and growing share of global emissions affecting climate, its overall contribution has not been quantified. We provide a comprehensive analysis of radiative forcing from the road transport, shipping, aviation, and rail subsectors, using both past- and forward-looking perspectives. We find that, since preindustrial times, transport has contributed ≈15% and 31% of the total man-made CO2 and O3 forcing, respectively."
