scope:

This Recommendation defines a KPI for the carbon emission intensity of a network focused on network energy consumption in relation to data traffic. It includes the KPI definition and describes the KPI calculation and methods of measurement of the quantities necessary to calculate the KPI.

The reporting of GHG emissions related to conformity or reporting in relation to [b-ITU-T L.1470] are outside the scope of this Recommendation, as are other related KPIs of potential interest.

A complete assessment of life cycle network GHG emissions is considered by Recommendation [b-ITU-T L.1410].

The network carbon intensity energy KPI is applicable to a complete network greenness assessment. It does not only encourage the reduction of network electricity consumption, but also the use of low-carbon energy supply and the improvement of energy utilization efficiency.

This Recommendation considers only the network operation phase, i.e., network energy consumption.

The Recommendation is applicable to the public telecom network (PTN), non-public network (NPN) and enterprise network.

This first edition of this Recommendation refers to data traffic intensities; however, future editions may include other metrics to describe services, such as the number of user connections.
