In Europe Apple are considered far from 'green' due to the problem of the power adaptors.

Every other phone or tablet sold in the E.U. has a sensible power adaptor, usually the mini USB flavour. Apple though, they don't think the law applies to them, or at least not the spirit of the law, so they keep churning out these Apple only power adaptors complete with the cables that fray and break a lot easier than normal cables.

Sure the data centres may be green but the landfill is not. Meanwhile, Google (who have far larger and more useful data centres) have been providing E.U. compliant power adaptors (or lack of) since the first Nexus phones, if not a long time before.
