Electronics disposal efficiency (EDE) is the percentage of decommissioned information technology electronics and electrical equipment that is disposed of through known responsible entities.
The electronic disposal efficiency metric was created by the Green Grid to help data center administrators measure their success in responsibly managing outdated equipment. The Green Grid is an international non-profit consortium that works to improve data center energy efficiency.
The EDE metric is intended to be used by an organization to set a benchmark and measure improvement over time. Calculating EDE requires the organization to know the weight of the equipment that has been decommissioned and its destination when it leaves the organization's control. The eventual goal is to transfer 100% of an organization's decommissioned IT equipment to a third party that has been certified to meet electronics recycling standards.
