- Abstract
- The ICT sector has experienced exponential growth in the last decades through the Fourth Industrial Revolution. This evolution was accompanied by many positive and negative impacts on different levels: social, economic and environmental. One of the most recognisable impacts is the carbon footprint of data centre storage, especially from the hyperscale structures of cloud providers. The aim of this qualitative study was to better apprehend the modern global phenomenon of Green IT by analysing its development and integration in the data centres, on a national scale. Different field experts were interviewed to that end, based on the main Green IT aspects identified in the literature review. It was revealed Green IT deployment in Belgian data centres is slow and requires new tools to optimise implementation and improve market interactions. After extracting the relevant information by themes, the adaptability of a framework was verified, and Porter’s five forces model was applied to better understand the underlying mechanisms of Green IT in the ICT sector. Several recommendations were elaborated to highlight improvement areas and guide field experts in future initiatives. Finally, the study limits were detailed as well as further research leads.
