The NY Times describes how people are selling counterfeit energy credits and making $ millions. More than $100 million in fraud has been identified.

Under the E.P.A. program, initiated in 2009, a producer who makes diesel fuel from vegetable oils and animal fats receives renewable energy credits for every gallon manufactured. The producer can then resell the credits to refiners, who pay millions of dollars for them under a government mandate to support a minimum level of production.

The credits can also be resold, a commonplace activity in the arena of corporate compliance with federal environmental rules.

The problem is that at least three companies were selling bogus credits without producing any biodiesel at all, the E.P.A. has said in announcements over the last year.
