Tailpipe Tally - Car Pollution Database

We recently found this online tool called Tailpipe Tally, but we forgot where it was that we saw the link (probably Triple Pundit). It was created by Environmental Defense and it is fairly simple to operate: You pick the vehicles that you want to learn more about, and it will create a table with the relevant information so that you can compare. In the first column it gives you the combined EPA fuel economy and the tailpipe emission rating, and in the following 6 columns you get: Estimated yearly fuel consumption, estimated yearly cost (although it is not very realistic - they assume gasoline at less than $2/gallon), carbon dioxide emissions (CO2), carbon monoxide emissions (CO), nitrogen oxides emissions (NOx) and hydrocarbon emissions.

In the example on the index page we can learn that a Toyota Camry will release approximatively 9,500 lbs (4,300 kilograms) of CO2 per year if driven 12,500 miles (20,100 kilometers) while a Toyota Prius will release 4,300 lbs (1900 kilograms) of CO2 per year if driven the same distance. Just make sure to take results with a grain of salt (you can learn about their methodology here). We've seen a few results that seem flat out incorrect, particularly in the last 3 columns. ::Tailpipe Tally
