ITU-T L.1333 (09/2022)

Carbon data intensity for network energy performance monitoring
To meet the targets of the Paris Agreement, telecom operators, like other industries, need to set targets for emission reduction to arrive at a net zero situation as reported in Recommendation ITU-T L.1470.
For a situation in which network traffic will increase, this Recommendation defines a key performance indicator (KPI) useful to evaluate network emission and give an indication on how a network can reduce its emission due to energy usage.
Recommendation ITU-T L.1333 defines a KPI called network carbon intensity energy (NCIe); it also defines how to apply the Recommendation: which part of the network is covered and how to calculate the metric continuously in network evolution.
This Recommendation also defines the correlation between the carbon intensity indicator and energy efficiency metric.
The carbon KPI defined in this Recommendation refers to the energy efficiency metric defined in Recommendation ITU-T L.1331.
