Ancillary Income from the Wetland

It is budget season for some of us and I was reading about carbon cap-and-trade the other day. The concept as I understand it limits the emissions that any one company can put into the atmosphere. If a company puts out more they are penalized in the way of buying up credits from other companies that fall below the cap. There is an entire market out there now for buying and selling these emission credits.
That being said, could we sell the credits we may have for the wet lands that our properties may be built around?
