Yawn.
It's not that I don't care about the environment. I do.
It's that most of this stuff makes no real difference, nor will it ever. I hate that Greenpeace and other groups use the force of public perception to get companies to do stuff like this instead of spending their time innovating and doing things that, through technological change, protect the environment.
You're right that most of this stuff is lip service but the conversation has to start before anyone will consider innovating in the name of conservation and the planet. Apple has changed the way smartphones, computers, retail stores, music and tablets are made and consumed. Some other large companies have followed their lead. I don't see any reason why they can't lead this environmental charge as innovators too.
