An annual report exposes the environmental lies corporations tell.

More than a decade ago, on Earth Day 1990, millions of people joined together around the country to protest the rapidly declining health of our planet -- forcing corporations to realize that even the average Joe had started to take an interest in the well-being of the environment.

Predictably, the level of "greenwashing" has spiked sharply since that eventful Earth Day. Greenwashing is what corporations do when they try to make themselves look more environmentally friendly than they really are.

Arguably, the greenwashers get away with it more often than not. But their deceptions do not go entirely unnoticed. Every year for the past decade, the watchdog group Earth Day Resources for Living Green has released a report called "Don't Be Fooled." The report calls attention to the year's 10 worst greenwashers, the 10 companies that have made the most misleading claims about the environmental benefits of their products and industries. This year, www.ecopledge.com, a coalition of environmental organizations that uses boycotts to put pressure on environment-abusing companies, has joined Earth Day Resources in putting out the report (available online at www.earthdayresources.org.)

"Don't Be Fooled" accuses corporations of deceiving consumers with false claims of environmental responsibility and all-natural wholesomeness. Not only does the report focus on deceptive claims made by corporations, it also highlights specific sins, falling into two main categories: producing genetically engineered foods and polluting the environment.
