I know that carpool programs pay carpoolers in the form of subsidized van commutes, so paying bike commuters seems only fair. Here in California there are such programs for air-quaility reasons -- vanpool 90 miles, walk or bike to work and one can earn some points that can be used to buy things at some special shop (or something like that). My current employer does not participate in the program.

I would like to get some carbon credits for my commuting efforts, with the intent to sell the credits on the open carbon market. I figure that if a firm can get credits for installing carbon-saving devices, and if another firm can instead pay cash to a carbon creditor in lieu of pullution controls, then I would like to participate, too, on principle if nothing else.

We get a metro/subway subsidy at around $55/mo. It's basically a check that I can use anyway I want to. If I were to take metro, it would cost me about $70 month. Employees can use the $55 towards paying monthly at a car parking lot, too. However, that costs from $100 and up per month. You also have to figure the cost of gasoline to drive in. I'm sitting pretty biking to work.

But you commuting only offsets your carbon emissions. Your commuting efforts do nothing to offset others emissions.

The whole concept of carbon trading is flawed so i don't see why a commuter couldn't sell their carbon savings.
