Biggest CO2 emissions
Top 40 most polluting cars. Updated October 2022.
Since 1990s vehicle CO2 emissions have decreased dramatically - thanks to advances in fuel injection technology, reduction of engine displacement and cylinder count (in exchange for turbocharging) and other technologies, like cylinder deactivation, start-stop and hybrid systems.
Fuel efficiency and CO2 emissions go hand in hand as they are essentially the same quantity expressed in different terms. Therefore, it is possible to calculate emissions for given fuel consumption and vice versa.
CO2 emissions and fuel consumption depend greatly on driving style and type of route. This list shows average CO2 emissions across all available data, which can be diverse and include both highway and city driving data. It also includes both factual (measured) CO2 emissions and calculated estimates.
Typically CO2 emissions are measured in grams per kilometer (g/km). For this list grams per mile (g/m) is used instead.
