# ISO/IEC JTC 1/SC 39

ISO/IEC JTC 1/SC 39 Sustainability for and by Information Technology is a standardization subcommittee of the Joint Technical Committee ISO/IEC JTC 1 of the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC), that develops and facilitates standards within the field of sustainability and resource efficiency through Information Technology. The international secretariat of ISO/IEC JTC 1/SC 39 is the American National Standards Institute (ANSI), located in the United States.

## History

ISO/IEC JTC 1/SC 39 was formed in November 2011 during the 26th Plenary Meeting of ISO/IEC JTC 1 in San Diego, California, with the intent of continuing ISO/IEC JTC 1's work in energy efficiency issues. The subcommittee was established after Resolution 27 was approved by ISO/IEC JTC 1, which outlined the new subcommittee's terms of reference, proposed working groups (WGs), and expected liaison activity. A working group on Energy Efficient Date Centres and its terms of reference were proposed in this document, though the title of the working group was later changed to Resource Efficient Data Centres. ISO/IEC JTC 1/SC 39 held its first plenary meeting in Redwood Shores, California in June 2012. The meeting concluded with the appointment of a chairperson to the subcommittee: director of global standards, codes, and environment at Schneider Electric, Jay Taylor.

## Scope and mission

The scope of ISO/IEC JTC 1/SC 39 is "Standardization related to the intersection of resource efficiency and IT which supports environmentally and economically viable development, application, operation, and management aspects."
The mission of ISO/IEC JTC 1/SC 39 is to use standardization related to the efficient use of resources to propel and sustain the economically and environmentally viable development of Information Technology.

## Structure

ISO/IEC JTC 1/SC 39 is made up of two working groups (WGs), each of which carries out specific tasks in standards development within the field of sustainability for and by Information Technology. The focus of each working group is described in the group's terms of reference. Working groups of ISO/IEC JTC 1/SC 39 are:
| Working Group | Working Area | Terms of Reference |
| ISO/IEC JTC 1/SC 39/WG 1 | Resource Efficient Data Centres | Development of: Data centre resource efficiency taxonomy, vocabulary, and maturity model Key Performance Indicators for data centres Guidance for resource efficient data centres Energy management system standard for data centres |
| ISO/IEC JTC 1/SC 39/WG 2 | Green ICT | Prepare guidance for the development of energy efficient ICT |
ISO/IEC JTC 1/SC 39 also has the Study Group on Gap Analysis which performs gap analyses for assessment methodology for quantifying green effects of ICT functions for education, and guidelines for the adoption of green technologies by other industry sectors through IT.
