Enhancing mobility options for millions while reducing negative impacts requires a combination of
approaches that avoid unnecessary travel through proper transport/land-use planning, shift to less
polluting and less energy intensive modes by encouraging mass transit oriented developments and
improve the overall fuel and vehicle efficiency through clean technologies. Lack of such interventions
would result in a major rise in emissions from vehicles - not only greenhouse emissions, but also local
air pollution, increased congestion and compromised safety standards. Furthermore, uncontrolled
urbanization will result in increased reliance on private motor vehicles and dependency on fossil fuels.
A sustainable transport sector needs to decouple increasing demand for mobility services from
emissions and dependence on fossil fuels. UNEP’s Green Economy Report demonstrates that with
available technologies and policies we can easily reduce global greenhouse emissions from the
transport sector by at least 70 percent.
