Energy efficiency

Technology has the potential to improve the way we live and work, but it can also carry risks to the environment. The ICT industry and its customers have a responsibility to minimise the adverse impact of ICT.

One way we can reduce the impact on climate change – and at the same time reduce operational costs – is by improving the energy efficiency of ICT products and services. Standards can help achieve this goal. ETSI accepted EC Mandate M/462 and is developing the standards needed to support the EC’s energy efficiency targets.

Our current work on the environmental aspects of ICT equipment includes energy efficiency.

Environmental Engineering committee (TC EE)

TC EE develops standards for reducing the eco-environmental impact of Information and Communications Technologies (ICT) equipment. This includes:

  • the Life Cycle Assessment (LCA) of ICT goods, networks and services
  • ‘the Green Abstraction Layer’, a standard on the power management capabilities of fixed network nodes, which enables operators for the first time to manage the energy consumption of telecom networks easily, offsetting network performance and capacity against energy costs
  • methods to assess the energy efficiency of wireless access networks and equipment, core networks and wireline access equipment
  • the control and monitoring of power and cooling systems used in telecommunication and data infrastructures, with the aim of monitoring and reducing power consumption
    power supplies
  • network standby mode for household and office equipment

Access, Terminals, Transmission and Multiplexing committee (TC ATTM)

TC ATTM focuses on the ‘green’ needs of operational networks and sites and broadband transmission including:

  • developing global Key Performance Indicators (KPIs) to provide users of ICT with the tools to monitor their eco-efficiency and energy management
  • defining the networks connecting digital multi-services in cities, producing KPIs for monitoring the sustainability of broadband solutions
  • improving our standards for transmission equipment to support the European Commission’s Ecodesign of Energy Related Products Directive

Energy efficiency is now a key focus of TC ATTM which is defining the general landscape of work required to address the energy consumption of all telecommunications equipment and systems. TC ATTM and Cenelec are working together on broadband implementation in Europe. Energy costs continue to rise, while broadband penetration is introducing new equipment to the network architecture. Energy consumption is therefore a major consideration affecting widespread broadband deployment.

Industry Specification Group (ISG) on Operational energy Efficiency for Users (OEU)

ISG OEU is working to minimize the power consumption and greenhouse gas emissions of infrastructure, utilities, equipment and software within ICT sites and networks. This includes:

  • the measurement of energy consumption by IT servers, storage units, broadband fixed access and mobile access, with a view to developing global KPIs
  • the management of the end of life of ICT equipment
  • a definition of global KPI modelling for green smart cities

Low power in the Internet of Things

Standards are also under development for technologies to provide low power to devices in the Internet of Things:
