Summary

Supplement 25 to the ITU-T L-series of Recommendation provides general principles and illustrates best practices on how information and communication technology (ICT) infrastructure can be adapted to cope with the effects of climate change.

Examples cited provide countermeasures to climate vulnerabilities identified in the Checklist in Recommendation ITU-T L.1502. These are: temperature rise, humidity, wind loading, sea level rise, rainfall, floods, landslides, snow and ice fall, lightning strikes and species damage.

Continuity of electric power supply is an important consideration in the event of electric grid failure, or failure of any other primary source of power. Functions that before were all in the same local system will have some of their functions possibly located hundreds of kilometres away, in a data centre. Such data centres may belong to services other than telecommunications. This will pose new challenges to primary service availability and continuity in case of occurrence of extreme events such as loss of power.
