|ITU-T L.1000: Universal power adapter and charger solution for mobile terminals and other hand-held ICT devices
||Recommendation ITU-T L.1000 provides high level requirements for a universal power adapter and charger solution that will reduce the number of power adapters and chargers produced and recycled by widening their application to more devices and increasing their lifetime. The solution also aims to reduce energy consumption. The longer life cycle and possibility of avoiding device duplication reduces the demand on raw materials and waste. The universal power adapter and charger solution is designed to serve the vast majority of mobile terminals and other ICT devices.

|ITU-T L.1001: External universal power adapter solutions for stationary information and communication technology devices
||Recommendation ITU-T L.1001 provides requirements for a universal power adapter solution (UPA) for stationary information and communication technology (ICT) devices that will reduce the number of produced power adapters by widening their application to more devices, enabling their reuse and increasing their lifetime. The solution also aims to reduce energy consumption. The longer life cycle and possibility of avoiding device duplication reduces the demand on raw materials and limits the amount of e-waste. The universal power adapter solution for stationary ICT equipment is designed to serve the vast majority of ICT devices.

|ITU-T L.1200: Direct current power feeding interface up to 400 V at the input to telecommunication and ICT equipment
||This Recommendation specifies the direct current (DC) interface between the power feeding system and ICT equipment connected to it. It also describes normal and abnormal voltage ranges, and immunity test levels for ICT equipment to maintain the stability of telecommunication and data communication services. The specified interface is operated from a DC power source of up to 400 V to allow increased power consumption and equipment power density, in order to obtain higher energy efficiency and reliability with less material usage than using a lower voltage such as -48 VDC or AC UPS power feeding solutions.

|ITU-T L.1300: Best practices for green data centres
||Recommendation ITU-T L.1300 describes best practices aimed at reducing the negative impact of data centres on the climate. It is commonly recognized that data centres will have an ever-increasing impact on the environment in the future. The application of the best practices defined in this Recommendation can help owners and managers to build future data centres, or improve existing ones, to operate in an environmentally responsible manner. Such considerations will strongly contribute to a reduction in the impact of the information and communication technology (ICT) sector on climate change.

|ITU-T L.1310: Energy efficiency metrics and measurement methods for telecommunication equipment
||Recommendation ITU-T L.1310 contains the definition of energy efficiency metrics test procedures, methodologies and measurement profiles required to assess the energy efficiency of telecommunication equipment. Metrics and measurement methods are defined for telecommunication network equipment and small networking equipment. These metrics allow for comparisons of equipments within the same class e.g. equipments using the same technologies. Comparisons of equipments in different classes are out of the scope of this Recommendation.

|ITU-T L.1400: Overview and general principles of methodologies for assessing the environmental impact of information and communication technologies
||Recommendation ITU-T L.1400 presents the general principles on assessing the environmental impact of information and communication technologies (ICT) and outlines the different methodologies that are being developed:
This Recommendation also provides some examples of opportunities to reduce the environmental load due to ICT.
- Assessment of the environmental impact of ICT goods, networks, and services
- Assessment of the environmental impact of ICT projects
- Assessment of the environmental impact of ICT in organizations
- Assessment of the environmental impact of ICT in cities
- Assessment of the environmental impact of ICT in countries or group of countries

|ITU-T L.1410: Methodology for the assessment of the environmental impact of information and communication technology goods, networks and services
||Recommendation ITU-T L.1410 deals with the assessment of the environmental impact of information and communication technology (ICT) goods, networks and services. It is organized in two parts:
Part I (clause 5) – ICT life cycle assessment: framework and guidance.
Part II (clause 6) – Comparative analysis between ICT and a reference product system (baseline scenario); framework and guidance.
Part I deals with the life cycle assessment (LCA) methodology applied to ICT goods, networks and services (ICT GNS). Part II deals with comparative analysis based on LCA results of an ICT GNS product system and a referenced product system.

|ITU-T L.1420: Methodology for energy consumption and greenhouse gas emissions impact assessment of information and communication technologies in organizations
||This Recommendation provides specific guidance on energy and greenhouse gas (GHG) impacts.
Recommendation ITU-T L.1420 presents the methodology to be followed if an organization intends to claim compliance with this Recommendation when assessing its information and communication technology (ICT) related energy consumption and/or greenhouse gas (GHG) emissions.
This Recommendation can be used to assess energy consumption and GHG emissions generated over a defined period of time for the following purposes: for assessment of related impact from ICT organizations or for assessment of impact from ICT related activities within non-ICT organizations.
