Why Did Apple Switch Back to Allowing EPEAT Certification?
Apple makes its products from, it does take issue with the construction of the latest devices. EPEAT requires that electronics be easy to disassemble with common tools. The Third Generation iPad and the next generation of Macbook Pro use proprietary screws, displays fused to the glass, and components glued together rather than fastened with screws, making them harder to disassemble for recycling purposes. It should be noted though, Apple Stores will take your retired or broken devices for recycling.
The move to withdraw from EPEAT could have sales ramifications for Apple with government, education, and corporate customers. Many of those institutions, including the U.S. Federal government, have policies that either require EPEAT certified devices or give strong preference to them.
