Apple's CEO Steve Jobs (or his marketing department) published a statement titled A Greener Apple.

The core message is that Apple plans to become greener. The statement talks about how Apple reduces toxic chemicals and is recycling their products.
Apple's policy of not trumpeting out future plans, limits the amount the company wants to disclose.
There are supposed to be future updates on the progress of Apple becoming a Granny Smith Apple.
