Transport decisions—at the national and municipal levels, but also globally—must go hand in hand with energy decisions if sustainable development is to be achieved and should include a shift towards high- efficiency and low-carbon modes of transport. Sustainable energy will, by definition, serve as a precondition for and ultimately further sustainable transport. However, in the short-term developed and developing countries alike will be looking to strike the right balance between assuring access to energy and transport for this generation and preserving the planet for the next.
