Introduction Global warming, climate change, green agenda, sustainable development, etc. are becoming more and more important and therefore it is important to address these issues also in the context of standardization. Since 1970, greenhouse gases have risen by more than 70 %, and this is having a global effect in warming the planet, causing changing weather patterns, rising sea-levels, desertification, shrinking ice cover and other worrying long-term effects. “Sustainable development is development that meets the needs of the present without compromising the ability of future generations to meet their own needs.”

ICT and global CO2 emissions ICT contributes as much as 7 % of global Gross Domestic Product (GDP).

ETSI Green Agenda The Green Agenda is one of the strategic topics for 2008 in the ETSI Board

ETSI Green Agenda activities Innovation/best practice Passive cooling Components for high temperature Implementation / use of ICT standardisation results - Intelligent Transport System (ITS) - eHealth Standardisation process - Electronic working - Paperless meetings since 1998 (3GPP start) Introduction of Green Agenda check list for all new work items Standardisation work Energy definitions Reference models Requirements Measurements etc. Specifications include solutions to reduce energy consumption; GSM….

ETSI standardization activities Examples Published deliverables TS 102 533 (2008-06): ”Measurement Methods and limits for Energy Consumption in Broadband Telecommunication Networks Equipment” This document establishes an energy consumption measurement method for broadband telecommunication network equipment; give contributions to fix target energy consumption value for wired broadband equipment including ADSL and VDSL. Active work items DTS/EE-00007: “Environmental Engineering (EE) Energy efficiency of wireless access network equipment” This work will establish wireless access network energy efficiency metrics, define efficiency parameters and measurement methods for wireless access network equipment. In the first phase GSM/EDGE, WCDMA/HSPA and WiMAX is addressed. Other systems, such as LTE, will be added when a stable system data is available.

Strategic Direction Climate change is a global concern and requires efforts from all industry sectors, including the Information and Communication Technologies (ICTs). ETSI is strengthening its efforts further in 2008 by Improving the tools for electronic work Introducing a check list that energy saving is considered for all new work items Initiating a number of new work items in the ICT and environment area ETSI proposes to collaborate on the Green Agenda with other partners through the Global Standards Collaboration (GSC)

Proposed Resolution Recognizing: that global warming, climate change, green agenda, sustainable development, etc. are becoming more and more important that since 1970, greenhouse gases have risen by more than 70 %, and this is having a global effect in warming the planet, causing changing weather patterns, rising sea-levels, desertification, shrinking ice cover and other worrying long-term effects. that sustainable development is a development that meets the needs of the present without compromising the ability of future generations to meet their own needs. that climate change is a global concern and requires efforts from all industry sectors, including the Information and Communication Technologies (ICTs). that ICT stands for ~2 % of the global CO2 emissions1 that ICT contributes as much as 7 % of global Gross Domestic Product (GDP)1. 1 year 2007

Proposed Resolution Considering: Resolves: that many GSC Participating Standards Organizations and ITU are already active in the area of ICT and the environment that standardization plays an important role in defining products and services, and should be the preferred tool to address technical issues related to the environmental performance of these Resolves: to encourage Participating Standards Organizations (PSOs) and Observer Organizations of the Global Standards Collaboration (GSC) to continue to: support ICT and environment as a High Interest Subject; bring a spirit of collaboration and mutual support to the development of ICT by taking the environmental aspects into consideration; and in particular addressing: awareness of ICT and the environment energy definitions, reference models, measurements methods and (where relevant) requirements in a harmonized way implementation and usage of ICT standardization results that have a positive impact on the environment electronic working and its tools.

Supplemental Slides

ETSI published deliverables 1(2) TR 102 531 (2007-04): “Better determination of equipment power and energy consumption for improved sizing” This document gives guidance on a more appropriate determination of equipment energy consumption with the goal to be able to realize a good design of power station and related power distribution network. A correct design help to have a better energy efficiency of power station with impact on the energy saving and with a not oversized dimensioning of power network permits to reduce the use of material (cupper) and as consequence a minor impact on the environmental and a cost reduction. TS 102 533 (2008-06): ”Measurement Methods and limits for Energy Consumption in Broadband Telecommunication Networks Equipment” This document establishes an energy consumption measurement method for broadband telecommunication network equipment; give contributions to fix target energy consumption value for wired broadband equipment including ADSL and VDSL.

ETSI published deliverables 2(2) EN 300 132-3 (2003-8): “Power supply interface at the input to telecommunications equipment; Part 3: Operated by rectified current source, alternating current source or direct current source up to 400 V”. This document standardizes a new power interface able to supply both telecom and ICT equipment. This solution permits to build only a power network, with backup, to supply energies at all type of equipment present in a data center without using UPS or AC/DC converters at 48 V so the global energetic efficiency of the entire system is greater that other solutions contributing and the energy saving. TR 102 530: “Reduction of energy consumption in telecommunications equipment and related infrastructure”. This document reports some techniques and some aspects to take in account during the evaluation of the possible reduction of energy consumption at equipment level and at installation level. The first version of this document refers principally at broadband equipment.

Active work items in ETSI 1(4) DTS/EE-00007: “Environmental Engineering (EE) Energy efficiency of wireless access network equipment” This work will establish wireless access network energy efficiency metrics, define efficiency parameters and measurement methods for wireless access network equipment. In the first phase GSM/EDGE, WCDMA/HSPA and WiMAX is addressed. Other systems, such as LTE, will be added when a stable system data is available. DTR/EE-00008: “Environmental Impact Assessment of ICT including the Positive Impact by using ICT Services” This work will define the methods to assess the environmental impacts of ICT, which have two aspects. i) Negative impact caused by the energy consumptions or CO2 emissions of operators of ICT equipments and sites including telecom network, users terminals, datacenters for residential and business services. Ii) Positive impact caused by energy saving or CO2 emission saving by using ICT services. We propose the method how to quantify such these impacts at national level.
