Our carbon footprint

Our carbon footprint represents the greenhouse gas emissions generated by our activities and depends, to a large extent, on our consumption of fossil fuels.

Our emissions depend to a large extent on our consumption of fossil fuels. Their decrease in 2021 (-37% compared to 2019, at constant scope) is mainly linked to the health crisis and the significant increase in homeworking, in addition to our efforts to reduce CO2 over several years.

Reducing the use of resources, avoiding waste

To become carbon-neutral, Belfius recently began working with CO2logic. The aim is to reduce energy consumption in our buildings, as well as limit waste, paper usage and staff travel.

‏‏‎ ‎‏‏‎ ‎


In 2020 and 2021, 100% of Belfius’ electricity consumption for its own operations, came from renewable sources.


Our water consumption at our head offices has drastically decreased since 2019, notably due to the increase in homeworking generated by Covid measures.


Employee awareness, coupled with the widespread use of laptops, has resulted in a 24% reduction of paper used for printing and photocopying versus 2019 - almost all of which is FSC certified.


In 2021, as in 2020, the homeworking measures imposed as part of the Covid crisis had a positive impact on the level of waste to be processed. At our head office, volumes were down by -57% compared to 2019. Belfius aims to maintain this trend and achieve a total reduction of 50% between 2019 and 2025.

Travel to and from work

In Today, 71.8% of employees at our Brussels headquarters use public transport to get to work and 2.8% make the entire journey by bicycle or on foot. These figures are the result of an ambitious mobility plan that has been in place since the early 2000’s.

Supporting the circular economy

Belfius has been involved in two Green Deals about Circular Purchases since 2017. Following on from the success of these two Green Deals in Flanders, in 2019 Belfius confirmed its commitment to the cause by signing the Walloon Green Deal (FR).

Belfius regularly makes its buyers aware of the principles of the circular economy and has created a special database as a source of inspiration for circular purchasing.

Green IT

In 2019, Belfius decided to join the Green IT Belgium club, with the agreement signed officially at the beginning of 2020. This membership will enable us to:

  • position ourselves better regarding the provision of sustainable IT services to our customers and staff.
  • have a better overview of the environmental footprint of our IT services so that we can reduce it in the future.
  • position ourselves better vis-à-vis similar companies.
  • exchange thoughts and best practices with other members.
