Jim "King Heineken" Dalrymple commenting on The Loop with regard to the Retina MacBook's Gold EPEAT rating and potential reasons for the move by Apple:
Maybe Apple saw the advantages of having the remainder of its product line on EPEAT even if the Retina models don’t make it. Seems odd though if you think that Retina is the future of the product.
My guess is that having products like the iMac and Mac Pro back in EPEAT, so that organizations/agencies with "must buy EPEAT products" policies, was important (for now). Many think the iPad is the future of computing, and it being a large portion of Apple's business never drove them to withdraw from EPEAT.
