Using air pollution and greenhouse gas emissions data from the Environmental Protections Agency, Forbes magazine has published a list of the 10 dirtiest vehicles on the road in America.

The EPA tests every vehicle vigorously using a scale rate of 0-10 and is based on the amount of the tailpipe emissions. They check for pollutants like hydrocarbon, nitrous oxide, particulate matter, carbon monoxide and formaldehyde.

The agency also uses fuel economy numbers to rate a car’s greenhouse gas levels looking specifically at carbon dioxide, nitrous oxide and methane.

The worst out of all was the Jeep Grand Cherokee and there was no Japanese cars that made it into the top 10.

Forbes have combined air pollution and emissions scores to determine the 10 dirtiest cars in America and here are the results.
