If you’ve got an iPhone, there’s an interesting new app that uses the built-in accelerometer to estimate and calculate your environmental variables in real-time, while driving. 

greenMeter is an app for the iPhone and iPod Touch that can compute your vehicle’s power and fuel usage characteristics, and help evaluate your driving style to increase efficiency, reduce fuel consumption and cost, and lower your environmental impact. Based on the gMeter vehicle performance app, greenMeter uses the device’s internal accelerometer to measure forward acceleration and compute engine power, fuel economy, fuel cost, carbon footprint, and oil (barrels) consumption.

More from CleanTechnica:

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 . 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.
