Our first annual review, covering our first reporting period, is now available. Rather than a traditional annual report, this document reflects on what building Slo has actually looked like over our first 18 months: the projects, the choices, the tensions, the lessons, and the questions we are still exploring.

For decades, organisations have pursued performance through growth, efficiency and optimisation. But in a world shaped by climate change, resource constraints and growing uncertainty, another question emerges: is performance enough? At Slo, we are increasingly inspired by the concept of robustness, the ability to adapt, evolve and thrive despite changing conditions. Not as a rejection of ambition, but as a different way of defining long-term success.

This study, conducted by Slo and Simont Braun for the Belgian Federal Public Service Economy, explores how companies operating in Belgium perceive and navigate the intersection between sustainability objectives and competition law. Through surveys, interviews, and comparative analysis, it examines the practical challenges businesses face when engaging in collaborative sustainability initiatives, and identifies policy levers to foster cooperation while ensuring legal compliance.
