Special Session on WHO EMF Activities
A Session on "Updates on WHO EMF activities" took place on 11 October 2016 within Q7/5. Dr. Emilie Van Deventer, Team Leader, Radiation Programme from WHO delivered a presentation on the "Updates of WHO on EMF". Her presentation is contained in
TD1734.
Connect 2020 Agenda
Two sessions on Connect 2020 agenda with a special focus on environmental sustainability goals took place on 11 and 12 October 2016.
On 11 October 2016 the session was dedicated to the Greenhouse Gas (GHG) emissions target of the Connect 2020 Agenda. This target advocates that GHG emissions generated by the telecommunication/ICT sector should be decreased per device by 30% by 2020. The session concluded with the creation of a new work item on “ITU-T L.Connect 2020 GHG emissions target, guidelines”. This new work item is contained in TD1741 Rev.2.
On 12 October 2016, the session was dedicated to the e-waste target of the Connect 2020 Agenda and was held within Q13/5. This e-waste target emphasizes on the need to reduce volume of redundant e-waste by 50% by 2020. TSB gave a short presentation related to the Connect 2020 Agenda e-waste target, based on the document contained in TD1710 . After the presentation, it was decided to create the following work items linked to the Connect 2020 Agenda e-waste target:
- Draft Recommendation ITU-T L.EW2020scen contained in TD1756 Rev.3
- Draft Recommendation ITU-T L.EW2020metrics contained in TD1754 Rev.2
- Draft Recommendation ITU-T L.EW2020frame contained in TD1753 Rev2.
Deletion of Recommendation ITU-T K.5 "Joint use of poles for electricity distribution and for telecommunications"
The last version of Recommendation ITU-T K.5 “Joint use of poles for electricity distribution and for telecommunications” was approved in 1988.
As the text of this Recommendation does not provide any specific advice, a new Recommendation ITU-T K.108 “Joint use of poles by telecommunication and solidly earthed power lines” was approved in 2015.
This new Recommendation ITU-T K.108, superseded ITU-T K.5 and provides advice for the joint use of poles. ITU-T K.108 is also adapted to the new requirements of the field.
For this reason, ITU-T SG5 agreed to propose Recommendation K.5 for deletion.
