Consideration of Assessment of Category 11 of Scope 3 Emissions in Case of ICT Solutions and Services

Abstract

Objective. The objective of this study is to consider the methodology to assess emissions of category 11（use of sold products）of Scope 3 in case of information and communication technology（ICT）solutions and services based on the data and experiences of assessment of more than 300 solutions and services using the environmental impact assessment method developed by Fujitsu Laboratories Ltd. in 2004.

Results and Discussion. Both direct and indirect use-phase emissions was assessed based on the emission factor per revenue. It is proposed to develop emission factors per ICT solutions and services categories as the way to improve accuracy of result. It’s also envisaged that the method described in this article could assess avoided emissions by comparative analysis with the reference scenario without ICT solutions and services. Consolidating guidance and emission factors for ICT solutions and services will help to improve the result of assessment.
