Mode Lbs CO2 Avoided/Mile Pounds of CO2 Generated per Mile
Bike 0.870 0.000
Walk 0.870 0.000
Bus 0.630 0.240
Train 0.500 0.370
Carpool 0.435 0.435
Small Electric 0.734 0.136
Electric Car 0.465 0.405

Drove Alone 0.000 0.870

We define the Greenest Travel prize category as: Lowest average CO2 emissions per mile (Most carbon efficient travel). This takes into account, to some extent, the fact that some green modes are better than others from an emissions standpoint. In fact, even with that we end with a lot of people doing 100% green travel (zero brown miles as you called it) by biking and walking only so we break ties using number of trips logged. The Most Green Miles by Mode categories avoid comparing train to bike miles, for example, which make sense too. Cheers, Bret Great ideas, Tom.

Just pick some common factors to multiply by each participant's miles traveled by mode. For example: Biking and walking: 0.0 lb CO2/passenger mile (pm) Driving solo: 1.0 lb/pm Bus incremental: 0.1 lb/pm Carpool average: 0.5 lb/pm Carpool incremental: 0.2 lb/pm Train incremental: 0.05 lb/pm (I made these numbers up. This is intended as food for thought. Your milage may vary.) With the type of data collected already you could display each participant’s estimated transportation operational carbon footprint.

(competitive spirit) I see you have included a prize scoring category for most green travel. I'm assuming that is most green miles. Perhaps it makes sense to add a categroy of highest percentage green miles. This way a pedestrian who moved close to work and walked 100% of trips (e.g. 20 miles in 2 weeks) could win a prize compared to a Sacramento ACE train rider who logs lots of green miles and some solo drive miles (e.g. 1200 train miles and 80 solo drive miles in 2 weeks) The Sacramento train rider still wins for the most green miles. There could be a little prize or honorable mention for every participant who was able to travel zero brown miles in two weeks. I believe in the power of gamification. (competitive spirit)

The developers are aware of it, and it will be fixed soon. There is a bug on that screen. The developers are aware of it, and it will be fixed soon.
