The UL 110 standard's "...requirements establish multiple attribute sustainability criteria for mobile phones, including the packaging and all components shipped in the box with the mobile phone." This standard will sync with the EPEAT registry in mid 2017.

"The criteria in these requirements were developed based on the life cycle stages of mobile phones and similar electronics. Sustainability factors considered in these requirements are: materials, packaging, manufacturing and operations, energy efficiency of the external power supply, health and environment, and end of life management. Credit for innovations in these, or other factors not listed, is also addressed in these requirements."

It was announced in February 2017 that, "UL Environment, a business division of UL (Underwriters Laboratories), a global safety science leader, and the Green Electronics Council (GEC), managers of the EPEAT program, today announced a collaboration enabling mobile phones certified to the ANSI/UL 110 sustainability standard to also be featured on the EPEAT Registry...A new mobile-phone category on the EPEAT Registry, based on the new UL 110 standard, is anticipated to be available to purchasers on 1 July."
