The sudden pullout — and subsequent return — of Apple from the EPEAT certification program it helped create increasingly appears to have been a dispute over the status that have been given to the Retina MacBook Pro if it were submitted, as the two 15-models with the high-resolution display may have been threatened with a lower-than-top ranking, a first for the company. The Retina models now appear on the EPEAT website with Gold rankings.

How is that possible?
