Title:
Progress status of ISO/IEC JTC 1 on Green ICT matters
1. Introduction
ISO/IEC JTC 1 studied on Green ICT matters to find future standardization initiatives. This
document summarizes progress results of JTC 1.
2. Progress history
Initially ISO/IEC JTC 1 took “Green IT” to study for its future standardization area at its 2008
Plenary meeting and assigned the study item to JTC 1 Special Working Group on Planning (SWGP). SWG-P delivered its study report, “A standardization initiative for Green ICT” to the 2009 JTC
1 Plenary meeting.
The 2009 JTC 1 Plenary meeting established two Study Groups and one SWG as follows:
 Study Group on Green ICT
 Study Group on Energy Efficiency of Data Centers
 Special Working Group on Smart Grid
The clause 5 of JCA-ICT&CC Doc 23 includes a summary of their activities. JTC 1 reconstituted
those two Study Groups at its 2010 Plenary meeting because they had one-year life between JTC 1
Plenary meetings.
The clause 5 of JCA-ICT&CC Doc 46 includes a summary of their activities conducted in 2011.
Finally in November 2011, JTC 1 established Sub-Committee 39, “Sustainability for and by
Information Technology.” JCA-ICT&CC Doc 77 includes specification information on this
establishment.
3. Current status
Currently four study items are on the New Work Item Proposal (NWIP) ballot process at JTC 1/SC
39 as follows:
 Power Usage Effectiveness (PUE) and Data Center Infrastructure Efficiency (DCiE)

-2 A Multilevel Taxonomy and related Data Centre Maturity Model To Assess Critical Facility
Energy Efficiency that can be harmonized in the Management Lifecycle, Design, Location,
Grade of Service and Workload contexts
 Best Practices for Green Data Centers
 Best Practices and Attributes for Green ICT Technologies and Standards Development
Those proposed items may be classified into two study areas: data center energy efficiency and
Green ICT development methods.
The first JTC 1/SC 39 meeting will be held in Redwood Shores, California, USA, June 12 – 14,
2012, where it will constitute its work group(s).
With following the cooperation philosophy, “Guide for ITU-T and ISO/IEC JTC1 cooperation,” of
ITU-T A.23 and ISO/IEC JTC 1 Standing Document 3, the NWIP on “Best Practices for Green
Data Centers” has been proposed as a joint project between JTC 1/SC 39 and ITU-T SG 5
according to liaison activities of JTC 1 and ITU-T SG 5 and their consensus where the liaison
activities are shown at JCA-ICT&CC Doc 45 and TD 989 Rev.1 (GEN/5).
The first item on “Power Usage Effectiveness (PUE) and Data Center Infrastructure Efficiency
(DCiE)” corresponds to the Key Performance Indicator item for green data centers. It may be
another cooperation item between both groups and also with ETSI TC EE.
