How is transport a source of noise polution?

Transport poses a dilemma in that it is necessary for economic and social development,

yet it is associated with environmental degradation, especially with regard to atmospheric

pollution. The transport sector accounts for about 25 per cent of total commercial energy

consumed worldwide, and consumes approximately one-half of total oil produced. Its emissions

include GreenHouse Gases, most notably CO2, as well as particulate matter, lead, nitrogen oxides,

sulfur oxides and volatile organic compounds all of which have negative impacts at local and

often at regional levels. In addition, it is associated with adverse noise and land use impacts
