Off the cuff solution
Let them do as they so wish in regards to cap and trade but with one catch .
Those who are pushing this must sign a paper which would bind them to an agreement that states if this idea turns out to be a fraud then they give up all monies that they have made in pursuit of said ideas and that they also pay for damages in relation and or go to prison for said fraud.
This would keep them HONEST .
