Do you have an iPhone? Here’s a pretty cool App that was just recently released by Hunter Research and Technologies that measures your car’s environmental impact. This is called the Greenmeter and what it does is it keeps track of your cars carbon footprint as well as your fuel efficiency. This app uses things like weather conditions, cost of fuel and vehicle weight to determine its calculations. The Greenmeter is most effective when placed on the dashboard between the two front seats but I wonder how good this app actually works. If anyone gets a chance to try it out let us know how good it is. You can look at the full picture below and If you want more info you can head over to Greenmeter and read more.
