Bad News For Al Gore

The Federal Trade Commission is investigating carbon offset scams.

Corporations and shoppers in the United States spent more than $54 million last year on carbon offset credits toward tree planting, wind farms, solar plants and other projects to balance the emissions created by, say, using a laptop computer or flying on a jet.

But where exactly is that money going?

The Federal Trade Commission, which regulates advertising claims, raised the question Tuesday in its first hearing in a series on green marketing, this one focusing on carbon offsets.

As more companies use offset programs to create an environmental halo over their products, the commission said it was growing increasingly concerned that some green marketing assertions were not substantiated. Environmentalists have a word for such misleading advertising: “greenwashing.”

With the rapid growth of green programs like carbon offsets, “there’s a heightened potential for deception,” said Deborah Platt Majoras, chairwoman of the commission.
