The main source of carbon monoxide (CO) emissions is the **combustion of gasoline and diesel fuel**. CO is produced when fossil fuels are burned in vehicles and machinery, where combustion is incomplete. While industrial processes and certain aerosols can contribute to CO emissions, vehicle emissions are the most significant source in many urban areas.
