Energy Star es una norma internacional para los productos de consumo eficiente de energía creada en 1992. Los dispositivos que llevan la marca Energy Star usan generalmente 20% -30% menos de energía que la media. ENERGY STAR Los productos eléctricos o electrónicos pueden contener pequeñas cantidades de sustancias peligrosas (RoHS de las siglas en inglés Restriction of Hazardous Substances). Según la normativa RoHS para cada producto se verifica la presencia de plomo (Pb), cadmio (Cd), mercurio (Hg), cromo hexavalente (Cr o Cr(VI)), polibromobifenilos o bifenilos polibromados (PBB) y polibromodifenil éteres (PBDE). PBB y PBDE son retardantes de llamas de fuego utilizados en varios plásticos. Para cadmio y cromo hexavalente se permite una presencia con una concentración máxima de 0,01% del peso del producto. Para Pb, PBB y PBDE no debe haber más del 0,1% del material. Según la normativa RoHS, cada producto puede tener hasta 100 ppm o menos de mercurio y el mercurio, no debe haber sido añadido deliberadamente al componente.

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. EPEAT Silver D means that the product is rated in its category in terms of energy efficiency. The Energy Labeling system is based on EU Regulation 2017/1369/EU.
