What pollutants are in car exhaust?
The following are the major pollutants from motor vehicles:
- Particulate matter (PM). One type of particulate matter is the soot seen in vehicle exhaust.
- Volatile Organic Compounds (VOCs).
- Nitrogen oxides (NOx).
- Carbon monoxide (CO).
- Sulfur dioxide (SO2).
- Greenhouse gases.
What does exhaust do to the environment?
Global Effects of Car Exhaust Car exhaust contains gases such as carbon dioxide that contribute to global climate change. Such gases trap heat in the atmosphere, creating a greenhouse effect that contributes to the warming of the Earth’s atmosphere, causing widespread climate change.
What is exhaust pollution?
Exhaust gas or flue gas is emitted as a result of the combustion of fuels such as natural gas, gasoline (petrol), diesel fuel, fuel oil, biodiesel blends, or coal. According to the type of engine, it is discharged into the atmosphere through an exhaust pipe, flue gas stack, or propelling nozzle.
How much air pollution does a car produce?
A typical passenger vehicle emits about 4.6 metric tons of carbon dioxide per year. This assumes the average gasoline vehicle on the road today has a fuel economy of about 22.0 miles per gallon and drives around 11,500 miles per year.

What human activities could increase the levels of carbon dioxide in our biosphere?
Burning fossil fuels, releasing chemicals into the atmosphere, reducing the amount of forest cover, and the rapid expansion of farming, development, and industrial activities are releasing carbon dioxide into the atmosphere and changing the balance of the climate system.
