Practice what you preach. Sustainability is in Factor4's DNA. Not only do we help others reduce their energy consumption and CO₂ emissions, we do it ourselves. Factor4 is a CO₂-neutral organization: we limit our own emissions as much as possible and offset the remaining emissions through a sustainable climate project.
How do we minimize our CO₂ emissions?
- We try to keep car use to a minimum. We do most of our travelling by public transport or bicycle. We make maximum use of the combination of train + BlueBike/folding bike, electric (shared) cars or carpooling.
- We consciously choose an office located just 5-minute walk from Antwerp Central Station (Mobiscore 9.9/10).
- We use a shared office where resources are shared with other entrepreneurs: common kitchen, meeting rooms, printers, and scanners. This helps limit our impact in terms of material and space usage.
- We embrace the principle of the paperless office and have built an IT infrastructure that allows full electronic management of projects.
Using Regreener's Footprint Navigator, we calculated our carbon emissions and more than offset them by participating in a sustainable climate project. We support tree planting in Zambia to contribute to a healthier climate. More information about this project: https://regreener.earth/nl/projecten/bomen-groeien-in-zambia

Factor4 supported Laakdal in the development of the strategic real estate plan. The objective: to structurally align municipal real estate with the public services provided by the local authority, both today and towards 2050.

Many local authorities manage an extensive portfolio of buildings, but often have limited capacity to structurally monitor their energy consumption. As a result, simple optimisations are frequently overlooked, even though these so-called “no-regret measures” can deliver fast and measurable energy savings.

In 2010, Factor4 was the first Belgian consultancy firm to examine the then relatively new and promising Dutch standard NEN 2767. This standard makes it possible to assess the technical condition of building components and installations in a uniform, objective, and reproducible manner.
