Title: Increased competitiveness and reduced environmental footprint thanks to Sustainable IT


Digital transformation is a priority for many organisations and is a crucial element of the energy transition. However, its negative environmental impacts are severely underestimated and can negate other efforts to reduce the carbon footprint. Digital technology can also become a source of exclusion. Understanding, controlling and reducing the environmental and social impacts of a company’s digital services therefore becomes an essential part of its CSR strategy. The icing on the cake is that adopting Sustainable IT can help reduce costs and give a significant competitive advantage! For administrations and public services, it is also a guarantee of accessibility and inclusiveness to better serve citizens.

But how to implement it in practice? This brief introduction to Sustainable IT will summarise the issues, provide practical answers and present the basic actions to be implemented in organisations, whatever their size or field.
