The environmental impact of transport is significant because transport is a major user of energy, and burns most of the world's petroleum. This creates air pollution, including nitrous oxides and particulates, and is a significant contributor to global warmingthrough emission of carbon dioxide.[1][2]Within the transport sector, road transport is the largest contributor to global warming

Transportation activities support increasing mobility demands for passengers and freight but at the cost of adverse environmental effects. The main adverse effects of transportation are:
Adverse Effects
(i) Air pollution:
Emissions of pollutants like CO2, NOx, particulate matter etc. from exhaust of vehicles are a major cause of air pollution.
(ii) Water Pollution:
Spillage during transportation of hazardous substances causes water pollution. Marine oil spills can devastate marine and coastal environments.
(iii) Biodiversity Loss:
Habitat fragmentation by roads or railway tracks leads to biodiversity loss. Transport allows urban expansion and damages natural habitats.
(iv) Biosecurity Risks:
International transportation of goods can allow new organisms to enter a region and increase risk for diseases.
(v) Noise:
The noise generated by vehicles can interfere with daily activities such as communicating or sleeping. It thus affects health of people. Transportation sector adversely affects our environment in all the stages of its operation.
