Summary:
|
This recommendation aims to describe specification for assessing the climate change risks of telecommunication and electrical facilities (as they are fundamental for the delivery of communication services) including overview, requirements and climate change risk assessment models.
1- The global climate changes are likely to profoundly affect the global telecommunication and energy sectors, which connect and power the world's economy. The telecommunication and energy sectors provide connectivity and fuel that propel the economy, including commerce, manufacturing, transportation, communications, healthcare, water supply and treatment, and other critical infrastructure and systems.
2- It becomes clear that the climate changes have potential for disrupting normal economic operations and quality of life. In addition to efforts to reduce the greenhouse gas emissions that may cause climate change, it is recognized that adapting to and preparing for climate impacts cannot be avoided anymore. Among the various energy sources, electricity infrastructure is indispensable to telecommunication services but is vulnerable to many natural disasters, such as earthquakes, extreme heat, thunderstorms, high winds, ice storms, and floods. In order to investigate the relationship between the climate changes and electrical facility, it is necessary to assess the risk for climate changes in terms of major types of climate change hazards. Recognizing the possible vulnerabilities of the electrical system, will enable telecom network designers to take the appropriate measures (outages, frequency and length, different back up sources, new generators, ...).
3- Currently, there are a lot of activities to provide regional and localized information and insights to support assessing risks and developing effective resilience strategies for telecommunication and electrical systems that are vulnerable to climate change impacts. These activities describe the key climate change trends, including rising temperatures and sea levels, changing precipitation patterns, and more frequent and severe episodes of extreme weather, that are already forcing telecom and electrical facilities to operate outside of the conditions for which they were designed and are threatening to damage or disrupt critical infrastructure.
4- There are activities to develop metrics in order to evaluate various risks of climate changes. However, since multiple risk metrics are under development, it becomes necessary to develop a simple and effective method for assessing overall risk of climate changes by using multiple metrics. Therefore, in order to develop a climate change risk assessment methodology, it is required to develop a new recommendation for describing the framework of climate change risk assessment for telecommunication and electrical facilities. The recommendation will include requirements and methodology for climate change risk metrics assessment.
