Green Drive keeps track of your CO2 and NOx emission if you drive a car or it tells you how much you have saved by biking, walking or driving an electric car.
Green Drive can also be used for painting TAGs live on huge screens as a participant in the CO2 Green Drive and other events around the planet.
So far there have been over 30 big events where Runners, Bikers, Skaters, Electrical Vehicles or Pedestrians have participated.
Continued use of GPS running in the background can dramatically decrease battery life.
