This edition of this Recommendation includes mobile networks, fixed networks, data centres, enterprise networks and end-user devices, but excludes ICT services.

The 1.5Β°C trajectories are developed from two different perspectives as follows.

The difference between the two perspectives A and B is that the latter does not allocate to the sector emissions related to the electricity supply (ES) chain and grid losses associated with the use of electricity in the ICT sector. The former more inclusive approach is aligned with life cycle assessment (LCA) practice and is in line with other Recommendations in the ITU-T L.1400 series. The latter approach is established as company accounting practice by the GHG protocol.

As the ICT sector is fast moving the trajectories developed at this point will need regular review over coming years.

Table III.2 – Embodied carbon footprint for network deployment and construction in Sweden and globally (estimated from Swedish data)

itu.2020.l1470greenhousegas (comment) (pg. 57)

Embodied emissions of mobile networks are calculated to remain at 2 kg CO2e/subscription and year based on [b-Malmodin 2018a] and [b-Malmodin 2018b].

Embodied emissions of fixed networks are calculated as 4kg CO2e/subscription and year based on [b-Malmodin 2018a].Β  Overall manufacturing is expected to decrease.
