ITU-T Climate Change Reports


Resilient pathways: the adaptation of the ICT sector to climate changeDownload
​The main objective of this report is to explore the impacts of climate change on the ICT sector and the potential for adaptation, while emphasizing the need for resilient pathways of action, enabling environments and new standards to foster the sector’s approach to adaptation.​April
Partnering for solutions: ICTs in Smart Water Management Partnering_for_Solutions.jpg ​Though economic growth, climate change and rising populations highly influence the availability of global water resources, strategic incorporation of ICTs in SWM can mitigate some of these challenges. Such achievements, however, are unattainable without proper stakeholder involvement and buy-in. The principal intention of this report is to go further and emphasize how ICTs can overcome some of the challenges faced in the water sector when there is proper stakeholder involvement. ​March 2014
The case of Korea: the quantification of GHG reduction effects achieved by ICTs​​Download report
​The purpose of this report is to demonstrate the potential GHG reductions by ICT services, estimate the reduced volume of GHG, and identify major ICT GHG reduction enablers in Korea. This report follows the methodology described in ITU-T Recommendation L.1410 and comprises a review of more than 30 ICT services through a literature study and global benchmarking. ​April 2013

Using submarine cables for climate monitoring and disaster warning: Opportunities and legal challenges Download report


Recognizing the newness of such uses of undersea telecommunications cables and the complexity of national and international legal-regulatory regimes, this report examines opportunities and legal challenges arising from dual-purpose telecom-marine data cables for ocean and climate monitoring and disaster warning. July 2012
Using submarine cables for climate monitoring and disaster warning: Strategy and roadmap Download report


This report presents a strategy and roadmap to move forward this vision of incorporating sensors into submarine cables. Nowadays, submarine telecommunication cables that traverse oceans transmit the global Internet, but are deaf, dumb and blind to their ocean environment around them. A future is envisioned when telecommunication companies integrate ocean-observing sensors within their submarine cable systems. This new sensory data would crucially advance our knowledge in monitoring global climate change and tsunamis in the deep ocean. July 2012
Using submarine cables for climate monitoring and disaster warning: Engineering Feasibility Study Download report


This report investigates technical feasibility of modifying repeaters to support science instruments for incorporation into commercial telecom cables systems. Allowing and improving long term measurement and data collection, a “Green Repeater" equipped with science instruments will indeed contribute to the effort of better understanding the oceans and the changing climate. July 2012
