Environmental Impact Assessment Method for Solution Services


The Fujitsu Group quantitatively assesses how much the environmental burden can be reduced when customers adopt its solution services, using an environmental impact assessment method developed by Fujitsu Laboratories Ltd.

Basic Concept of Environmental Impact Assessment

The effect of adopting solution services is converted into the environmental effect.

The environmental effect of adopting solution services (e.g., paperless method (reduction in the use of paper), productivity improvement, work efficiency improvement) is quantitatively calculated and converted into CO2 emissions.

Assessment Target

Solution services can be considered to have their own life cycles consisting of multiple stages including planning, development, use, and disposal (e.g., renewal of the system). The present assessment method targets the use stage that take place at customers' locations.

Impact Assessment Factors (7 Factors)

Environmental impacts are quantitatively assessed for the following 7 factors:

Environmental impact factorData required for calculating environmental impact
Resource consumptionPaper, CDs, documents, etc.
Movement of peopleAirplanes, trains, buses, automobiles, etc.
Transport of goodsSmall trucks, commercial-use trucks, rail freight, air freight, etc.
Office spaceSpace per person, server machine space, etc.
Warehouse spaceGeneral warehouses, refrigerated warehouses, etc.
Power consumption of ICT/ network equipmentPower consumption by ICT and network equipment
Data communication traffic volumeVolume of data trafficking the network (includes volume of data trafficking LAN)

Steps of Environmental Impact Assessment

  1. Assess CO2 emissions by environmental impact factor
  2. Compare CO2 emissions-reducing factors and CO2 emissions-increasing factors before and after adopting solution services

Web-based Environmental Impact Calculation Tool

"EcoCALC," a web-based tool for estimating environmental contribution, quantitatively evaluates the effectiveness of ICT in reducing environmental load with regard to CO2 emissions before and after the introduction of ICT. Using this environmental impact evaluation method, this tool calculates the amount of CO2 emissions reduced by ICT as the amount of contribution, and is used globally as an in-house tool by the Fujitsu Group. We are utilizing this tool to proactively promote environmental contribution amount calculations for business negotiations and new solutions.


In 2011, the web-based environmental impact calculation tool EcoCALC was awarded the Special Award by the judges at the 2011 Green IT Awards. The award recognizes the innovation and originality of a tool that uses ICT to visualize reductions in CO2 emissions, and commends the active use of this tool in client proposals.

Efforts for Standardization

The Fujitsu Group aims at contributing to the global efforts on reducing the environmental burden though diffusion of ICT. Standardization is one of such efforts, and Fujitsu actively participates in various activities at external organizations such as an international organization for standardization. Below are the examples of Fujitsu's contributions to standardizing the methods to evaluate the environmental burden reduction effect of ICT solution services.

  1. "FY2005 Guideline for Information and Communication Technology (ICT) Eco-Efficiency Evaluation"PDF
    This guideline includes the general framework, principles, and requirements relating to evaluation of the environmental impact of ICT and environmental burden reduced by adopting ICT. Formulation of the guideline was entrusted to the Japan Environmental Management Association for Industry by the Ministry of Economy, Trade and Industry, and was conducted by 8 ICT companies who are the members of the Japan Forum of Eco-efficiency and the University of Tokyo. The Fujitsu Group assisted the project by providing actual evaluation cases and by composing some parts of the guideline.
  2. ITU-T (International Telecommunication Union, Telecommunications Standardization Sector) Recommendation "Methodology for the assessment of the environmental impact of information and communication technology goods, networks and services (L.1410)" (2013)Open a new window
    The present Recommendation stipulates an internationally universal framework of "Methodology for the assessment of the environmental impact of information and communication technology goods, networks and services", whose establishment was mainly promoted by the Ministry of Internal Affairs and Communications of Japan. The Fujitsu Group participated in "ICT and climate change (SG3 WP5)" of ITU-T as an associate rapporteur.
  3. Participated in IEC/TC 111 WG 17 domestic meetings. Fujitsu is cooperating in the development of international standards with the aim of publishing IEC 63372 "Quantification and communication of GHG emissions and emissions reductions/avoided emissions from electric and electronic products, services and systems – Principles, methodologies and guidance" in FY 2023/24.
