GreenDrive from Road-Guard was selected as a runner-up for the European Satellite Navigation Competition in 2008. GreenDrive works by suggesting the most economical driving style to the driver. When you’re too slow or too fast it’ll tell you to speed up or break so you’re always driving close to the optimal speed for fuel efficiency. GreenDrive can be installed on GPS navigation devices or GPS powered cell phones.
GreenDrive™ is an award-winning solution that guides drivers to develop smart, smooth, and safe driving techniques that lead to an average fuel savings of 15-25% and positively contributes to environmental protection.

British Vexia just announced environmentally friendly GPS navigation systems that will help you save money and protect the environment with its software that tells you the optimal way to drive. All you have to do is enter your car type, fuel type and occupancy level, and the system will direct your to a route that is easiest on your wallet and mother nature. Vexia Econav can even advise you on which gear to use, and their accelerator pedal indicator will comment on the weight of your right foot.
