Luminus publishes every year a very detailed, multi-awarded Sustainability report. In 2024, the 2023 Sustainability report was chosen as the “best” Belgian report in the category for “large, non quoted companies”. Luminus wishes to continue to publish such a comprehensive report, to make sure it remains a Sustainability front-runner in the energy sector.

Goals of the assignment

The 2025 Sustainability report has to be published before June 30, 2026. To reach this deadline, collecting facts and figures starts in January. Some chapters need a simple update, others an upgrade – to make sure Luminus keeps its current EcoVadis Platinum medal. The goal is to produce a preview of the report end of April, then the complete report.

Learning benefits

Contributing to the publication of such a report is an ideal assignment if you are looking for a first transverse full-time work experience at the end of your studies. You will learn to interview experts, to produce qualitative texts and write objective comments on multiple KPIs – on diverse topics. Chapters you can participate in include Ethics, Customer Satisfaction, Energy Solutions and Human Resources.

You will thus get acquainted with a complex, challenging sector – especially from a Sustainability point of view. You will also learn how to deal with sensitive topics, such as health & safety, inclusion, supply chain monitoring, stakeholder dialogue, etc.
