I was able to easily map all of my vehicles in order for them to be tracked with EMI (Emissions Measurement Information). This allowed me to see how much each vehicle contributes towards our overall CO2 output as well as allowing us to have some control over where we spend money reducing those contributions. The only thing so far is when it comes time to change out an old engine or transmission there are not many options available like other programs do. It would also benefit from being more user friendly if you don't already know something about computers then this program can take awhile at first until someone familiar enough steps through training you along the way. Tracking fuel usage has been beneficial because now everyone knows what their individual cars contribute which helps us make long term decisions regarding purchasing new equipment such as engines/transmission replacements, etc. We try and use less gas than before by using tracking. Also makes sure people who drive older.
