According to iFixit, the entirety of Apple's computing portfolio has been removed from the Electronic Product Environment Assessment Tool (EPEAT) Gold program, citing the inability to easily disassemble and recycle its products.
As reported by iFixit:
According to my EPEAT contacts, Apple's mobile design direction is in conflict with the intended direction of the standard. Specifically, the standard lays out particular requirements for product "disassemble-ability", a very important consideration for recycling: "External enclosures, chassis and electronic subassemblies shall be removable with commonly available tools or by hand." Electronics recyclers need to take out hazardous components such as batteries before sending computers through their shredders, because batteries can catch fire when punctured.
As an interesting by-product of the decision, US federal agencies can no longer purchase Apple computing products.
