The key principle of a fuel data management system is always the same: To manage fuel consumption. Local governments can take a variety of approaches to doing this, ranging from manually tracking mileage (with pen and paper) to collecting instant fuel consumption with on board computers. Each local government will be different and find one technique that provides a better cost / benefit than all the rest.
The more actively you can manage your fleet’s fuel consumption, the more effectively your fuel data management system will inform the strategies you take to reduce GHG emissions.
Be sure to always relate fuel consumption into business outputs, such as fuel consumed by distance traveled, hour, tonne, or person and create opportunities to differentiate between business units, vehicles, and employees. This will allow you to take more targeted action and foster the desired change.
