Apple announced July 13 that it will relist its products to the Electronics Product Environmental Assessment Tool, calling its June decision to remove the products a mistake. Developed in part by a grant from the Environmental Protection Agency to the Zero Waste Alliance, EPEAT is an environmental rating system that lists more than 2,800 products from 48 different manufacturers. The Obama administration directed the General Services Administration last July to remove all products not certified by EPEAT or Energy Star from government IT contracts.
