Carbon monoxide (CO) — cars emit carbon monoxide when fuel is burned. … Nitrogen dioxide (NO2) — when fuel burns, nitrogen and oxygen react with each other and form nitrogen oxides (NOx). Nitrogen Dioxide (NO2) forms from emissions from cars, trucks, buses, power plants and off-road equipment.
How do cars cause pollution?
Carbon monoxide- This odorless, colorless gas is formed by the combustion of fossil fuels such as gasoline. Cars and trucks are the source of nearly two-thirds of this pollutant. … Sulfur dioxide- Motor vehicles create this pollutant by burning sulfur-containing fuels, especially diesel.
How much do cars pollute the air?
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. Every gallon of gasoline burned creates about 8,887 grams of CO2.
How do we stop air pollution?

What causes the most pollution?
Most of the air pollution takes place due to the burning of fossil fuels such as coal, oil, gasoline to produce energy for electricity or transportation. The release of carbon monoxide in high level indicates how much fossil fuel is burned. This also emits other toxic pollutants in the air.
How much does cars contribute to global warming?
Highway vehicles release about 1.6 billion tons of greenhouse gases (GHGs) into the atmosphere each year—mostly in the form of carbon dioxide (CO2)—contributing to global climate change. Each gallon of gasoline you burn creates 20 pounds of GHG. That’s roughly 6 to 9 tons of GHG each year for a typical vehicle.
What is pollution from cars called?
Carbon monoxide (CO).
This odorless, colorless, and poisonous gas is formed by the combustion of fossil fuels such as gasoline and is emitted primarily from cars and trucks.
