(A.) Policy and legislation

(A.1) Policy objectives

ICT is currently one of the fastest growing greenhouse gas-emitting and energy management sectors.

At the level of ICT, multiple methodologies are available to assess the environmental impact of ICT itself, but they do not provide a consistent methodological framework for this assessment. A solution to this is the work developed in various European and International standardisation bodies such as ETSI, ITU-T, IEC, ISO and others, around methodologies to assess this environmental impact, currently focused on energy management including energy consumption and greenhouse gas (GHG) emissions, with the achievement of good consensus. This work is performed in collaboration with industry, standardisation bodies and public authorities. The criteria for measuring the impact of ICT on the environment will be extended to other environmental sectors, like water and raw materials.

A key challenge is achieving transparency around claims relating to the environmental performance of ICT products and services, and setting an effective basis to drive competition.

(A.2) EC perspective and progress report

The Commission is looking at the environmental impact of ICT from various fronts:

(C.) Activities and additional information  

(C.1) Related standardisation activities

Standardisation request M/462 on efficient energy use within broadband deployment was accepted by the ESOs to provide standards for measurement and monitoring, including the definition of energy-efficient KPIs. This standardisation request is not only limited to networks, but extends as well to data centres and other ICT nodes associated with broadband deployment. It is currently in phase 2. 

Energy and more general resource management in data centres are addressed by a cross-ESO coordination group (Coordination Group Green Data Centres – CG-GDC). This group monitors European and international standardisation for data centre resource management (including energy) and maintains a live executive summary of that activity.

The CEN-CLC-ETSI CG-GDC encourages standardisation activity to support Commission objectives and has recently asked CENELEC to undertake the conversion of DG JRC Best Practice Guidelines for the Code of Conduct for Energy Efficient Data Centres  into a standards-based format linked to the EN 50600 series. 


CLC/TC 215 is responsible for a holistic series of ENs for the design, operation and resource efficiency of data centres (including KPIs) from a system point of view. Several CENELEC technical committees are responsible for energy efficient products deployed in data centres.

CLC/TC 111X ‘Environment’

CEN/CLC/JTC 10 Energy-related products - Material Efficiency Aspects for Ecodesign


ETSI’s technical committees for Access, Terminals, Transmission and Multiplexing (TC ATTM), Cable (TC CABLE) and Environmental Engineering (TC EE), collaborate to develop standards in response to EC Mandate M/462 on enabling efficient energy management (efficient use of energy) in fixed and mobile information and communication networks and sites. The resulting standards cover global KPIs for energy management covering ICT sites (e.g. data centres, transmission nodes), mobile broadband access networks, fixed broadband access networks and cable access networks. These global KPIs are to support the deployment of eco-efficient networks and sites and to monitor the energy management of deployed broadband. These new KPIs, which will be used to define green sites and networks for all industrial and commercial users, are outlined in a series of ENs (EN 305 200 Series) based on ETSI’s existing KPIs and TSs for energy efficiency in broadband deployment. The KPIs will provide ICT users with tools to monitor the energy management of networks and sites in full compliance with the Kyoto Protocol on climate change and the reduction of greenhouse gas emissions. EN 305 174 Series defines the most efficient engineering of ICT networks and sites in order to support the efficient deployment of these networks and sites. Also available are a range of standards for measurement methods for energy efficiency of fixed and mobile networks.

Recent work includes new ENs for energy efficiency Key Performance Indicators (KPIs) for servers and for Radio Access Network equipment, a focus on evaluating energy efficiency of future 5G networks, and work on multiservice street furniture, outlining processes to improve energy efficiency and to ease the deployment of smart new services in digital multiservice cities. EN 305 174-8 on broadband deployment and lifecycle resource management for the end of life of ICT equipment (efficient waste management) was also finalized. This EN will support future standards on field implementation of ICT waste management.

Furthermore, TC-EE is developing standards for the energy and material efficiency of ICT network equipment and this includes the standard for the implementing Regulations of the eco-design directive 2009/125/EC. In this contest, ETSI has already published the standard EN 303 423 “Environmental Engineering (EE); Electrical and electronic household and office equipment; Measurement of networked standby power consumption of Interconnecting equipment; Harmonised Standard covering the measurement method for EC Regulation 1275/2008 amended by EU Regulation 801/2013”

Based on the response to EC Mandate M/462, TC CABLE is extending the EN 305 200 series with a set of ENs standardizing an approach to energy efficiency in communication networks based on the assessment of network design and architecture. Taking into account current practices of the stakeholders represented in TC CABLE, this enables efficient design and operation of communications infrastructures end-to-end from the core network to the end user.


Starting at the level of `good, networks and services´, they have approved methodologies for environmental impact assessment. These will make it possible to assess in a transparent, qualitative, accurate and consistent way the footprint and other aspects of various products and services that are part of everyday digital life, such as email, telephone services, laptops, broadband access. In addition, companies, public bodies and other organisations will be able to assess and report their ICT footprint based on ITU’s “ICT in Organisation”.

ITU and ETSI have also agreed a new standard to measure the energy efficiency of mobile radio access networks (RANs), the wireless networks that connect end-user equipment to the core network.

The standard (Recommendation ITU-T L.1330) is the first to define energy-efficiency metrics and measurement methods for live RANs, providing a common reference to evaluate their performance. Its application will build uniformity in the methodologies employed by such evaluations, in parallel establishing a common basis for the interpretation of the results.

ITU ITU-T SG5 is developing a series of standards aimed at reducing greenhouse gas emissions and energy consumption. In this regard, some of the international standards developed are listed on this site: 

ITU-T SG5 is also developing a series of standards aimed at reducing electronic waste and transitioning to a circular economy (ITU-T L.1015, ITU-T L.1020, ITU-T L.1021, ITU-T L.1030, ITU-T L.1031, ITU-T L.1100, ITU-T L.1101, ITU-T L.1102, ITU-T L.Suppl.4, ITU-TL.Suppl.5, ITU-T L.Suppl.20, ITU-T L.Suppl.27, ITU-T L.Suppl.28). Moreover, it is working to set the environmental requirements for 5G. There are four key aspects: Electromagnetic compatibility (EMC); Electromagnetic fields (EMF); Energy feeding and efficiency; and Resistibility. A series of standards on this topic have already been developed (ITU-T L.1220, ITU-T L.1221, ITU-T L.1222 , ITU-T K. Suppl.4, ITU-T K. Suppl.8, ITU-T K. Suppl.9, ITU-T K. Suppl.10, ITU-T K.Suppl.14, ITU-T K.Suppl.16, ITU-T K.Suppl.36).

In addition, ITU-T SG5 also develops standards that aim to assess the sustainability impacts of ICTs and adapt ICT infrastructure to the effects of climate change within the framework of the Sustainable Development Goals (SDGs), including Recommendation ITU-T L.1440 - Methodology for environmental impact assessment of information and communication technologies at city level. The European Commission through CNECTH5 acted as chief editor. For more standards developed by SG5 on related topics, see: More info:

ITU is also developing two reports, entitled “Turning digital technology innovation into climate action” and “Frontier technologies to protect the environment & tackle climate change”, to highlight the emerging role of ICTs and digital technologies in accelerating climate actions.

ITU-T Focus Group “Environmental efficiency for artificial intelligence and frontier technologies” (FG-AI4EEE) was created in May 2019 to identify the standardisation gaps related to the environmental performance of AI and other emerging technologies including automation, augmented reality, virtual reality, extended reality, smart manufacturing, industry 5.0, cloud/edge computing, nanotechnology, 5G, among others. The focus group will develop technical reports and technical specifications to address the environmental efficiency, as well as water and energy consumption of emerging technologies.
