Yes....Cars emit carbon dioxide as part of their emissions. Cars are a part of the global warming problem. Cars produce mostly CO2 however, when there is incomplete combustion especially in older vehicles and tricycles, CO (carbon monoxide) is produced which are harmful to breathing and the respiratory system.
Burning one gallon of gas creates 20 pounds of carbon dioxide, and the average car emits about six tons of carbon dioxide every 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.
Greenhouse gas (GHG) emissions from transportation account for about 29 percent of total U.S. greenhouse gas emissions, making it the largest contributor of U.S. GHG emissions.
Yes.....They produce more CO2 than older cars due to their engine capacity nonetheless, Older cars produce more emission of harmful gases due to their incomplete Combustion Circle.
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.
