Every two years, Greenargile (a dedicated in-house tool) is used to measure the environmental footprint of the IT equipment used by users (computers, screens, printers, etc.), the IT network infrastructure and the data centres.
A major IT inventory was carried out in 2015 and 2018, and updated in 2020. This inventory serves as a basis for calculating the carbon footprint of equipment within the scope of La Poste SA and La Banque Postale for scopes 1, 2 and 3.
The Greenargile solution evaluates the GHG emissions of the IT equipment by taking into account the three phases of the life cycle (production, use, end of life). The energy consumption of digital equipment in 2020 has been estimated at 376 GWh. The volume of associated GHG emissions is relatively low (44,559 tonnes), as the electricity used to power the buildings and equipment is 100% renewable.
Work is ongoing to complete this "internal" footprint measurement with emissions and consumption related to outsourced data centre services. The objective of scope 3 (concerning services such as dry and data hosting, facilities management and management in cloudSAAS mode) is to establish a methodology for measuring the volume of GHG emissions over the 2020 period in the digital domain in order to prepare for the integration of these emissions into the measurement of the Group's emissions from 2021.
In addition, La Poste contributes annually to an external benchmark(2), GreenIT.fr, in order to measure the footprint of its fleet and its maturity in the field of responsible digital technology, bringing together several large French companies (Airbus, Pôle emploi, Decathlon, etc.).
