Mac users out there are feeling very "green" right now, if word has reached them that Apple has become the newest company to join the hasty exodus from corporate front group U.S. Chamber of Commerce. The computer software company announced their exit from the corporate front group today over their climate change policies in a letter from Apple Government Affairs VP Catherine A. Novell to U.S. Chamber President Thomas J. Donohue.

"We strongly object to the chamber's recent comments opposing the E.P.A.'s effort to limit greenhouse gases.

"Apple supports regulating greenhouse gas emissions, and it is frustrating to find the chamber at odds with us in this effort."

Although the Environmental Protection Agency and most climate scientists agree that greenhouse gas emissions are warming the Earth, the Chamber of Commerce begs to differ. They've opposed curbs on greenhouse gas pollution, via either cap-and-trade or mandates under the Clean Air Act. It's likely Apple's reasons for ditching the Chamber also include the group's recent call for a "21st century version of the Scopes Monkey Trial" to determine if global warming was real-- equating climate change with creationism.

The U.S. Chamber of Congress has served as a unifying agent for three major energy companies, Nike and now Apple, in the ever-growing list of companies who don't share their out-of-touch policies that favor Wall Street and greedy CEOs.
