ITU-T SERIES L SUPP 54 PDF

This Supplement to ITU-T L.1400 series of Recommendations gives guidance for assessing the greenhouse gas (GHG) emissions consequences of financial effects (gains or losses) generated by an information and communication technologies (ICT) solution or ICT company, separately considering the user and the vendor financial benefits or losses from the solution. It thus assesses the GHG impact of this common case of rebound effect due to changes in behaviour.

More specifically it addresses financial effects on GHG emissions due to:

• changes in first order effects of ICT solutions (e.g., if reductions in energy consumption of networks lead to financial gains);

• changes in second order effects of ICT solutions (e.g., if reductions in travelling due to an ICT service leads to financial gains);

• changes in activities to reduce organizations' GHG emissions of ICT organizations (e.g., if an ICT company reduces its own travelling);

• other changes in organizational activities of ICT organizations (e.g., economically more attractive conditions for renting facilities unrelated to their energy consumption).

Financial gains or losses can be generated by the use of the ICT solution (i.e., on the customer or buyer side) or by the sale of the solution (i.e., on the vendor side). The guidance in this Supplement applies to both the vendor and the buyer (user), the only distinction being whether the buyer is an individual (or household) or a business.

NOTE – The approach described in this Supplement acknowledges that financial gains could be used in ways that either increase or decrease GHG emissions.
