CBC Manitoba has added the Bike Benefit Calculator to their website. This fun tool gives you a idea how much you can save over a year (in calories, bucks, and CO2) by riding your bike to work. Just enter the distance to work. Easy peasy.
There is lots “wrong” with this calculator, of course. It doesn’t take into account the type of car you drive, for example. And it rates your carbon footprint on the bike as zero. But it is still interesting to see what a BIG difference there is between the various modes of transportation.
