The EPEAT program provides independent verification of manufacturers’ claims and the EPEAT online Registry lists sustainable products from a broader range of manufacturers than any comparable ecolabel. National governments, including the United States, and thousands of private and public institutional purchasers around the world use EPEAT as part of their sustainable procurement decisions. EPEAT helps purchasers, manufacturers, resellers, and others buy and sell environmentally preferable electronic products. EPEAT-registered products must meet environmental performance criteria that address: materials selection, supply chain greenhouse gas emissions reduction, design for circularity and product longevity, energy conservation, end-of-life management and corporate performance. Bronze-rated products meet all of the required criteria in their category. Silver-rated products meet all of the required criteria and at least 50% of the optional criteria, while Gold-rated products meet all of the required criteria and at least 75% of the optional criteria.
