Ever heard the term "Greenwash" before? Well, it's a bit like whitewash but used in an environmental context.

If you're unfamiliar with the term, whitewash basically means "Concealment of flaws or failures" as in to "gloss over" misdemeanours, faults or errors.

"Greenwash", according to Webster's New Millennium Dictionary of English, means;

"the practice of promoting environmentally friendly programs to deflect attention from an organization's environmentally unfriendly or less savory activities; also called greenwashing"

So, the moral of the story is; If a company claims environmental credentials, be sure to check them out and don't forget; make sure you're not diverted from it's other activities, they may not be so green after all.
