This thesis explores the sustainability challenges and opportunities within the data center sector, with a specific focus on Atea, a leading player in the digital infrastructure industry. As organizations increasingly depend on IT systems for operational efficiency, the environmental impact of data centers has come under scrutiny. With the increasing demands for sustainability driven by both market forces and stringent EU regulations, this study examines how organizations, particularly within the data center industry, can adapt to meet these emerging requirements. This study aims to contribute an understanding of strategies and measures that can be implemented to achieve more sustainable data center operations. Our research employed a qualitative methodology, incorporating both literature review and a case study to gather insights into sustainable practices in the data center industry. Atea’s role as a case study provided practical perspective on the implementation of sustainability strategies within the sector. The findings highlight significant challenges, including energy consumption, waste management, and regulatory compliance. Conversely, the study also identifies opportunities such as the adoption of green technologies, improved energy efficiency, and strategic waste reduction practices. The implications of this research are twofold: it offers a roadmap for data centers aiming to enhance their sustainability profile, and it contributes to the broader discourse on the environmental responsibilities of the IT-sector. Future research should investigate the real-world impact of new EU regulations in the data center sector, focusing on how national legislation aligns with EU requirements and their practical application by data centers.
