The greenMeter, recently released by Hunter Research and Technologies, is an iPhone application with a mission to keep track of your car’s carbon footprint and fuel efficiency (as you can see in the picture below).

The program uses a multitude of variables to make its calculations, including weather conditions, cost of fuel, and vehicle weight. More advanced measurements such as drag coefficient, vehicle pitch, and rolling resistance can be calculated using estimates available on the company’s website.

It’s been said the greenMeter is most accurate if it is placed on the dashboard or console between the two front seats. If you’re a keen environmentalist and is planning on trying out the greenMeter, just be careful that you don’t run into the problem of looking at the screen more than the road!

The greenMeter is available for download from the iTunes App Store for $5.99, it runs on the iPhone as well as the iPod Touch (for iPhone, firmware 2.0 or above is required).
