Answer:

"Vehicular Pollution" would include:

• air emissions such as photochemical smog precursors like nitrogen oxides and hydrocarbons, carbon dioxode, aromatic hydrocarbon emissions, particulates
• liquid emissions like lost fuel, lubricants and coolants

It generally is not taken to include the emissions and wasted associated with the production and disposal of the vehicles themselves and the fuels used in them.

Vehicular pollution causes local effects such as urban air quality and global problems such as climate change. The reduction of vehicle emissions is primarily related to the amount of fuel used and can be reduced by the reduction of that consumption.
