Why cars are bad for the environment?

Car pollution is one of the major causes of global warming. Cars and trucks emit carbon dioxide and other greenhouse gases, which contribute one-fifth of the United States' total global warming pollution. Greenhouse gases trap heat in the atmosphere, which causes worldwide temperatures to rise.

In this regard, how do cars pollute the environment?

Dirty cars, dirty air. In 2013, transportation contributed more than half of the carbon monoxide and nitrogen oxides, and almost a quarter of the hydrocarbons emitted into our air. This air pollution carries significant risks for human health and the environment.

How do gasoline cars affect the environment?

Gasoline use contributes to air pollution. The vapors given off when gasoline evaporates and the substances produced when gasoline is burned (carbon monoxide, nitrogen oxides, particulate matter, and unburned hydrocarbons) contribute to air pollution. Burning gasoline also produces carbon dioxide, a greenhouse gas.

How much do cars pollute the air?

How much CO2 do cars emit? Adam: Burning one gallon of gas creates 20 pounds of carbon dioxide, and the average car emits about six tons of carbon dioxide every year. But averages don't tell you much about your own carbon footprint, which is as personal as your fingerprint.
