Seminar : Towards a "more sustainable" IT

Digital transformation is a priority for many companies and is a critical component of the energy transition. However, its negative impacts on the environment are severely underestimated and can negate other efforts to reduce the carbon footprint. Understanding, controlling and reducing the environmental impacts of a company’s digital services is, therefore, an essential part of its CSR strategy. But how to do it concretely?

This seminar is organized by HEC Liège Executive Education and the Digital Lab.
