Information and Communication Technologies (ICT) represent the convergence of information technology, communication technology, and digital systems. It is a modern field that combines these areas to create innovative solutions for various sectors. In addition to being a technological discipline, ICT also refers to an online testing device used in network diagnostics.
The International Telecommunication Union (ITU) plays a significant role in addressing global challenges such as climate change and environmental protection through the development of ICT standards. The ITU-T, which is the standardization sector of the ITU, has been actively involved in promoting the use of ICTs to support sustainable development and reduce environmental impacts.
At the World Telecommunication Standardization Assembly (WTSA-12) in Dubai in 2012, ITU’s 193 member states adopted Resolution 73, focusing on the relationship between ICT, the environment, and climate change. This resolution emphasized the importance of integrating ICT into environmental strategies and encouraged the adoption of green technologies across industries.
ITU-T Study Group 5 leads the organization’s efforts in researching environmental and climate-related issues. Current work items under this group include:
- Q13/5: Reducing the environmental impact of e-waste.
- Q14/5: Developing low-cost, sustainable telecom infrastructure for rural areas in developing countries.
- Q15/5: Enhancing ICT applications for climate adaptation.
- Q16/5: Improving the environmental sustainability of ICTs.
- Q17/5: Coordinating energy efficiency and environmental standards in the ICT industry.
- Q18/5: Establishing methods for assessing the environmental impact of ICT.
- Q19/5: Improving power supply systems for ICT infrastructure.
In terms of environmental impact assessment, ITU-T is working on standardized methodologies to evaluate the environmental footprint of ICTs. These methods consider both the direct emissions from the ICT sector and the indirect benefits from using green ICT solutions in other industries. This initiative involves collaboration with over 60 organizations, including the UNFCCC and UNEP.
The ITU-T L.1400 Recommendation outlines the fundamental principles for assessing and reporting the environmental impact of ICT. It covers various domains such as ICT products, networks, services, projects, organizational ICT systems, city-level ICT, and national or regional ICT systems.
Additionally, the ITU-T L.1410 Recommendation provides standardized methods for evaluating the environmental impact of ICT products, networks, and services, based on the Life Cycle Assessment (LCA) methodology defined in ISO 14040 and ISO 14044.
The ITU-T L.1420 Recommendation focuses on assessing energy consumption and greenhouse gas emissions within organizations, setting clear guidelines for improving sustainability in ICT operations. These recommendations help ensure that ICT development aligns with global environmental goals and supports long-term sustainable growth.
