FYI

I came across this really great website that gives you all the information about your car and gives a detailed description on the fuel economy and the environmental impact. I was quite fascinated by it so I thought I'd share.


Here's the info on my car for example:

What's the difference between air pollution and greenhouse gas emissions?The Air Pollution score and Carbon Footprint measure different types of vehicle emissions. Air pollutants harm human health and/or cause smog. Carbon Footprint measures greenhouse gas emissions (primarily CO2) that impact climate change.
