Scope
This Recommendation specifies methodologies for assessing the environmental impact of information and communication technology (ICT) at a sector level including its future development. It consists of two parts: 1) Part I: The methodology for calculating the footprint of the ICT sector with respect to life cycle greenhouse gas (GHG) emissions; 2) Part II: The methodology for defining a GHG emissions budget for the ICT sector considering a 2?C or lower trajectory. It also applies the methodology of Part I and gives an example of a partial ICT sector footprint derived in line with this Recommendation (Appendix IV). A GHG emissions budget for the ICT sector could either take an organizational approach or be derived from the perspectives of the goods@ networks and services of a sector. Each approach has its own challenges@ although the latter has been more commonly adopted in the past. For this reason@ in this edition of the Recommendation@ the methodology focus is on the second approach ?C a footprint and budget related to ICT goods@ networks and services. However@ some observations and ideas for an organizational approach are presented in Appendix III.
