ITU-T L.1050 PDF

The objective of this Recommendation is to provide best practices for equipment identification for ICT service architecture designers to be able to evaluate the environmental performance of different network architectures.

The Recommendation will specify the necessary requirements for identifying equipment types used in network life cycle assessments (LCAs). The proposed set of equipment can be used to evaluate the following dimensions of network architecture:

– Energy efficiency

– E-waste amounts

– LCA impacts

– Circularity indicators [ITU-T L.1023]

NOTE – Applying [ITU-T L.1023] to a network (in order to achieve a single 0% to 100% score for the network) requires allocation (e.g., based on share of cost, share of environmental impact, share of mass, share of functional performance) of the individual [ITU-T L.1023] scores of the equipment composing the network.

This not an exhaustive list. While it does not give network architect designers environmental impact values for each equipment, for the environmental performance calculation of network architecture, it does provide a solid baseline for the scope and overview of network architectures for later calculation of environmental footprint indicators.
