Transportation Activities Affecting the Environment
Transportation activities involve separate modes supporting the movements of passengers and freight (within or between modes). Each has an environmental impact:
  • Infrastructure. Construction and maintenance of transport infrastructure requires resources (materials), energy and land.
  • Vehicle manufacture. Involves the resources and energy consumed in the manufacturing process.
  • Vehicle travel. The outcome of transport vehicle use, which varies by mode, usually involve the consumption of fossil fuels.
  • Vehicle maintenance. The consumption and disposal of parts during maintenance, including lubricants.
  • Vehicle disposal. Once the useful life of a vehicle is over, it must be disposed and recycled.
Not mentioned are telecommunication infrastructures that are consuming materials and energy as well.
