My company does provide some incentives for carpooling and mass transit, and partners with the Clean Air Campaign. For cyclists, and anyone else who participates, there is a random drawing for $25 gift cards. For car-pooling and riding buses there are additional monetary incentives.

I had a conversation with the guy who runs the Clean Air Campaign in Georgia. I was curious why there were additional incentives for people taking cars and none for cyclists. After all, cycling is friendlier to the environment than driving, so it would be logical to encourage it more. He told me, and it makes sense, that people who ride-share for three months tend to stick with it, while people who bike tend not to. The incentives are intended to help build a habit, rather than as a reward. And, for us who do stick with cycling, it's not necessarily about the money - not the $30 or so incentive level of money anyway. Those of us who do have a car (and that's who they'd target, regular sole-occupant commuters) but commute by bike anyway, generally have additional reasons. And to be honest, I told him that I'd bike even if it didn't save any money at all because for me it was simply a better way to get to work.

So there you have it - the incentives don't reliably produce bike commuters, and committed bike commuters will do it anyway. The ROI is better for incentives for mass transit and ride-sharing. Corporate thinking can run along the same lines, the one difference is that the more forward-thinking will consider the health benefits to productivity and insurance costs. But there's not a lot of hope there for cycling incentives.
