The EU GPP criteria consist of core criteria, which are fit for any contracting authority in the member states, and comprehensive criteria for those wishing to purchase the environmentally best performing products on the market.242 The focus will merely be on the comprehensive criteria as the study strives to map out the most comprehensive criteria on resource efficiency. The EPEAT labels on computers and imaging equipment have from 2010 been introduced worldwide.247 EPEAT provides three rating categories, gold, silver, and bronze. Products are qualified according to two types of criteria: Required and Optional. For a product to be awarded with the label the product must comply with all the required criteria, but whether the product is rated gold, silver or bronze depends on how many of the optional criteria the product meets.248 In the following presentation of resource efficiency criteria, only the gold rated criteria are included as the intention is to gain experiences from the most comprehensive examples of resource efficiency requirements.
