Development of International Standard for Assessing Energy Management Progress for Organizations, ISO TS 50011

Many countries have set targets for energy efficiency improvement and greenhouse gas emission reduction as measures against global warming. To achieve them, organizations are required to achieve their own targets. Therefore, energy management systems are becoming important for organizations. In the International Organization for Standardization (ISO), Technical Committee (TC) 301 developed ISO 50001: 2018 to establish requirements for improving energy performance and energy management system (EnMS) with a plan-do-check-act (PDCA) cycle. In this PDCA-cycle, organizations are required to improve systems before/after ISO 50001 implementation. To maintain organizations' motivation for the improvement activities, methods for assessing their improvements and showing their efforts are required. Therefore, the Japan Electronics and Information Technology Industries Association (JEITA) suggested an international standard for assessing the energy management of organizations and has led the development project. In this study, the development of the international standard process including clarification of the background and current problems are explained. Furthermore, a consensus in ISO discussions is discussed and the outline of the published standard is described.
