Q11/5: Climate change mitigation and smart energy solutions 

The Co-Rapporteurs of Q11/5 (Ms Qi Shuguang & Mr Sangjin Jeong) opened the meeting and presented the draft agenda contained in TD91-R5​, which was approved with modifications.

All twelve contributions were reviewed and the documents under study were improved based on the Contributions received. Thirty-six incoming Liaisons were discussed in detail, and two outgoing liaisons were prepared. 

It was agreed that two draft Recommendations were proposed to be consented in ITU-T SG5 Plenary. The new Recommendations are
ITU-T L.10 kVAC_up to 400 VDC “Specifications of 10 kVAC input and up to 400 VDC output integrated power system in data center and telecommunication room” and ITU-T L.ESE “Evaluation method of safety operations and energy saving for power supply system in telecommunication room/building”. Also, one new Supplement was proposed to be agreed upon in SG5 Plenary, which is ITU-T L.Suppl.dces “Data center energy saving: Application of AI technology in improving energy efficiency of telecommunication room and data center infrastructure”.

Three new work items for Recommendations regarding greenhouse gas emission monitoring and measurement and waste heat re-use in data were initiated based on the discussion. The new work items are ITU-T L.DMA “Methodology for dynamic monitoring and analysis of greenhouse gas emissions in city”, ITU-T L.GHG_management “Framework and Functional Requirements of Greenhouse Gas Emissions Management System for Public Sectors”, and ITU-T L.WHR “Specification for Waste Heat Reuse in Telecommunication Rooms and Data Centres”. 

Draft Recommendations ITU-T L.PSU_for server “Methodologies for evaluating the functionality and performance of power supply unit configured for servers”, and ITU-T L.NZ solutions “Best practices to achieve Net Zero with information and communication technologies” were progressed based on the Contributions and discussion. 

In addition, it was agreed to revise ITU-T Supplement 44 to ITU-T L-series Recommendations “Guidelines on best practices and environment friendly policies for effective information and communication technology deployment methods” based on the Contribution and discussion. 

The proposal to initiate the development of a new Supplement regarding “Questionnaire on ITU-T Recommendations on Environment, Climate Change, EMF and Circular Economy (“Green ITU-T Rec”) at the national policies and regulations” was discussed based on C7-R1. As the scope of the proposal exceeds the scope of Q11/5, it was proposed to address the issue in the WP3/5 Plenary. 
After further discussion during the WP3/5 plenary, it was decided not to open this work item given the lack of consensus on this proposal. 

The report of the Q11/5 meeting is contained in TD151-R1.

Q12/5: Adaptation to climate change through sustainable and resilient digital technologies 

The Rapporteur of Q12/5 (Messrs Claudio Bianco & Derick Khamali) opened the meeting and presented the draft agenda contained in TD92-R2, which was approved with modifications.

Q12/5 experts met (online and in person) and addressed the Contributions and Temporary Documents received to Q12/5. A total of seven Contributions were received, namely C16-R1, C17-R1, C76-R1, C86, C87, C88, and C89 while eight Temporary Documents were submitted, namely; TD36-R1, TD37-R1, TD38-R1, TD59, TD60, TD100, TD136, and TD164.

The Q12/5 meeting reviewed the Contributions and Temporary documents and proposed Supplement ITU-T L.Suppl.oa2cc – “Overview on Adaptation to Climate Change for ICT Networks” (TD236-R1) for agreement. Q12/5 experts also proposed the following four new work items, for approval:
The Q12/5 acknowledged information contained in TD100 on the work carried out by TC111, as well as ISO/IEC JTC 1 SC39 and the content of TD164 on liaison report from ISO/TMBG/CCCC noting that this was valuable information that will aid in the development of the proposed new Recommendations.
 
The Q12/5 Members agreed to hold e-meetings on a monthly basis and seek to attract more members from across the ITU membership to participate in its work as per the updated work programme.  

The report of the Q12/5 meeting is contained in TD152-R2.

Question 8/5 - Guides and terminology on environment and climate change

During this meeting, Q8/5 experts reviewed four incoming Liaison Statements and prepared the respective responses.

Most of the Q8/5 activity has been concerned with liaison vocabulary. The IEEE 802.3 working group is intent in preventing ITU from using the abbreviations SPE (single pair Ethernet) and SPoE (single pair power over Ethernet) – yet these are commonly used and established ISO/IEC terms. In an effort to obtain Author's Guide compliance, Q8/5 will check consented Recommendations in AAP.

The meeting report of the Question 8/5 can be found in 
TD148-R1.
