ICTs and Energy Efficiency

ITU is committed to promoting energy efficiency by driving down emissions and reducing the carbon footprint within ITU and other organizations by facilitating the incorporation of ICT-enabled solutions and methodologies into several sectors and industries.

While ICTs have been estimated to contribute 2 to 2.5% of the global greenhouse gas (GHG) emissions, it also has the potential to assist with the reduction of GHG. With the development of standards on ICTs, environment and climate change and the recognition of the central role of power feeding and data centres, ITU plays a leading role in improving of energy efficiency.

Introducing the Issue: ICT Equipment and Energy Efficiency

ICTs can play a transformative role in securing a sustainable and energy efficient future. They can also be refined to be more environmentally sound and less carbon intensive.

ITU's successful contribution to generating awareness on ICT-based solutions is evidenced by the upward trajectory of improved energy efficiency through smart grids and intelligent sustainable buildings along with green data centres and green power feeding systems which too are based on ITU-T Recommendations.

Standards on Environment and Climate Change

ITU is one of the three international standards developing organizations (SDOs) recognized by WTO. Through its ITU-T Study Group 5, has developed a set of standardized methodologies to assess the environmental impact of ICTs in cooperation with ICT industry and other key stakeholders.

Green ICT Power Feeding

Power feeding systems play a vital role in the energy consumption of ICT equipment connected to it. Taking into consideration the improvement in energy efficiency techniques and the need to reduce greenhouse gas (GHG) emissions, ITU-T Study Group 5 has developed a number of Recommendations on power feeding systems. ​​

Detailed information on these ITU-T Recommendations can be found here.

Green Data Centres

ITU-T Study Group 5 has specifically developed a series of Recommendations addressing several aspects of data centres. The following Recommendations list is specific to data centres, but the other L-series Recommendations on Green ICT Standards can also be relevant.
