Wondering where Apple stands environmentally after the recent withdrawal (and subsequent return) of its laptops and desktops from the EPEAT rating system? Greenpeace has issued a well-timed report, outlining the company's broader back-end energy policies. According to the organization, "Apple's clean energy policies have significantly improved, but the company still gets low scores for its energy choices when compared with sector leaders." Greenpeace applauds Cupertino's commitment to goal coal-free by next year, but wonders aloud how the company will get there, noting that while it has invested in solar and other renewable energy sources, it still buys power from outlets that rely on coal. The organization also took the time to admonish Apple's lack of transparency on its environmental plans.
