Project objectives

The project answers to a dual objective:
1. Conducting a complete inventory and measuring the environmental footprint of Capgemini France IT capabilities
2. Deploying reduction levers until 2022

Detailed project description

Capgemini started its sustainable digital transformation involving all French based entities by driving change in IT usage and operating models, and by onboarding all employees.


Between November 2020 and March 2021, Capgemini realized:


  • A qualitative maturity assessment on the 4 pillars of the sustainable IT methodology developed inhouse

  • A quantitative audit of CO2e emissions generated by the layers of its IT, resulting in the confirmation of its main sources:
  1. IT hardware, essentially laptops and screens
  2. Data centres, due to their energy consumption
  3. Data transmission

  • The definition of its strategy and associated roadmap to reduce total emissions generated by its IT layers by 24% (hardware, data centres, network) before 2024, focusing on its main hotspots. The roadmap is based on 17 levers shared between CSR, IT department, Procurements, HR, and Business entities.

The initialization of the reduction roadmap

Emission scope(s)

Emission scope(s) on which the project has a significant impact

Scope 1

Direct emissions generated by the company's activity.

Scope 2

Indirect emissions associated with the company's electricity and heat consumption.

Scope 3

Emissions induced (upstream or downstream) by the company's activities, products and/or services in its value chain.

Emission Removal

Carbon sinks creation, (BECCS, CCU/S, …)

Avoided Emissions

Emissions avoided by the activities, products and/or services in charge of the project, or by the financing of emission reduction projects.

Scope 2 – Reduction of energy consumption

  • Quantification: 50 tCO2 avoided per year

Scope 3 – IT equipment all along their life cycle

  • Quantification : 1 150 tCO2 avoided per year
    1. Calculation of the emissions
      Methodology developed by Quantis relying on Life Cycle Analysis (LCA) and based on Capgemini France’s IT assets and parameters (example of indicators: PUE, storage technologies (SSD / HDD), renewal rate of hosts…).


    1. Identification of major sources of emissions
      ~70% GHG : Physical IT hardware unit (90 000+) : laptops, screens, printers, phones, accessories…
      ~20% GHG : Impacts of datacentres hosting applications, storing and processing data
      Energy consumed for data transmission


    1. Identification and prioritization of reduction levers
      Examples below:


    Target differential by 2024

    Decreasing number of equipment per employee


    Extending computers’ lifetime


    Increasing computers’ reconditioning rate


    1. Calculation of the total expected GHG reduction (-24%) and spreading reduction over time

Illustrations of the project

The project contributes to the following SDG:

  • SDG 12 – Responsible consumption and production, by:
  • Training employees on sustainable IT development and consumption modes, in link with the CSR strategy
  • Onboarding suppliers in the sustainable IT journey

The opportunity of scaling the initiative at Capgemini Group level is currently under investigation. The approach would be to replicate the designed methodology to all other IT departments and consolidate levers deployment at international level.
