I work for a large corporation which is trying to be more environmentally friendly. They asked for suggestions and I proposed giving some sort of compensation to employees who ride their bikes (i.e. monthly cash bonus, extra vacation days, etc...). I got a positive response back from them and they are asking me to back up my claims with quality reputable sources. That's where you guys, and gals, come in. I want to provide the best data possible and I know the people in this message board are totally capable of providing it.
Here are the claims I made and that will need to be backed up:
1. People riding bikes to work lowers pollution by having less cars on the road.
2. Employees who bike to work are more productive at work.
3. Bike commuters take less sick days and go out on disability less because they live a healthier lifestyle.
Those are the benefits I came up with. However, if you can think of any others, and back them up, feel free to let me know. Any help would be greatly appreciated!
