The American National Standards Institute has approved ANSI/SCTE 234 2016, "ISO 50001:2011 Energy Management Systems, Energy Metrics, With Guidance For Use." The SCTE's Energy 2020 Program is a multi-year campaign that aims to provide cable operators with the energy management standards, technology innovation, organizational solutions and training to help the cable industry meet Energy 2020's goals. In 2011, the International Organization for Standardization (ISO) published 50001: Energy management systems - Requirements with guidance for use. The SCTE's Energy 2020 Program aligns with the underlying principles of that publication, and SCTE 234 2016 serves as the recognition of that international standard as the official cable industry standard.
