Passenger cars produced approximately three billion metric tons of carbon dioxide emissions worldwide in 2020. The emissions produced by passenger cars have been steadily rising over the past two decades, increasing from 2.2 billion metric tons in 2000 to a peak of 3.2 million metric tons. Emissions fell roughly six percent in a 2020 as a result of the COVID-19 pandemic, which caused major disruptions to transportation.
