ESG (environment, social and governance)

What does ESG actually involve?

The impact of IT companies is becoming more and more important. Cybersecurity and the use of innovative new technologies like artificial intelligence and the cloud (public, hybrid and private) all represent crucial challenges for the development of modern companies.

These challenges increase our responsibility towards the public and are an incentive for us to adopt sustainable and ethical practices. Respecting the environment, ensuring the wellbeing of our employees and maintaining exemplary governance practices are imperative if we are to guarantee responsible and sustainable business.

ESG criteria are essential for measuring the sustainability and integrity of our company. At NRB, we have been committed for a number of years to embedding these principles in our vision and our mission. Our commitment is reflected in our policies and is confirmed by our ISO 9001, 20000 and 27001 certifications. We are determined to continue along this path, convinced that the future of IT must be sustainable and ethical. l'avenir de l'IT doit être durable et éthique.

NRB has high environmental ambitions. The company aims to reduce its carbon emissions on its historic Herstal site by 80% by 2030, and by 100% by 2050. To achieve this, a number of initiatives have been implemented and the results obtained in recent years prove their effectiveness.

Installation of a wind turbine and photovoltaic panels

In June 2022, NRB inaugurated the very first wind turbine at the heart of Wallonia’s biggest business park, in Herstal. This installation was a key step in our “Green IT” offer.

The wind turbine and the 940 photovoltaic panels installed on the roofs of our buildings are producing tangible effects, confirming our commitment to achieving carbon neutrality by the middle of the century. In 2023, 60% of the electricity consumed on the Herstal site came from these renewable resources, avoiding the emission of 1963 tonnes of CO2 into the atmosphere (figures based on the Walloon Region’s methodology). Moreover, the rest of our electricity is 100% green, which gives us a zero carbon supply.

Some of the greenest Data Centres in Belgium

Cybersecurity is crucial to a company’s survival. NRB offers both a private and a hybrid hosting platform via its two Data Centre campuses in Herstal and Villers-le-Bouillet. These infrastructures guarantee the physical security of the data of numerous Belgian and international companies

Our own company has taken several measures to limit the environmental impact of its Data Centres:

  • The energy provided by the wind turbine, the photovoltaic panels and our green energy supply mean we can count on zero-carbon data centres.
  • Cold corridors make it possible to cool only specific zones of the Data Centres, thereby optimising energy efficiency.
  • Heat recovery systems capture the thermal energy produced by the Data Centres and redistribute it to the offices occupied by our employees.

Household and industrial waste sorting, the Walloon carbon convention, etc.

NRB is stepping up its initiatives, at every level, to reduce its environmental impact.

  • Our employees are encouraged to sort their household waste, with special bins at their disposal in the workplace.
  • Our company also optimises the sorting of its industrial waste. Waste from the Data Centre (cardboard and old servers) is entrusted to specialised recycling companies, so that it can be processed and reused.
  • NRB has joined the Walloon carbon convention, which focuses on three objectives: reducing CO2 emissions, producing green energy and improving energy efficiency.
