Sound transportation infrastructure and policies can improve connectivity and competitiveness, link people to markets and social services, stimulate economic growth, increase climate resilience and reduce carbon footprint. Transportation infrastructure facilitates the movement of people and goods and is vital for sustainable development. Transportation and the environment are closely interlinked and interdependent. Key elements of transportation infrastructure include roads, ports, airports and rail, and urban transportation systems. Transportation projects can have negative effects on the environment and local communities if not adequately addressed in the design and implementation of programs and projects; with the transport sector being a major source of energy consumption. Sustainable transportation projects, such as clean urban transportation systems and more environmentally friendly port and airport operations, provide not only economic development but important social and environmental benefits as well. The development of transportation that takes into account social inclusion and environmental sustainability helps benefit the poor and promote equal opportunities.
