ABSTRACT
Digital companies must be prepared to integrate sustainability into their digital and global expansion strategies. The impact of sustainability on internationalisation performance can either drive progress or create obstacles. With more countries adopting sustainability regulations, businesses expanding internationally face increased scrutiny from stakeholders. This chapter aims to deepen understanding of how businesses can effectively integrate sustainability into digital internationalisation strategies. The goal is to identify sustainability engagement areas and challenges in digital internationalisation. Through case studies of three digitally internationalised companies – Ecosia, Too Good To Go, and Vinted – the research identifies areas where sustainability intersects with digitalisation and international growth. Evaluating multiple cases reveals common factors and unique differences in the sustainability approaches of these companies. The case study analysis is supported by existing literature on sustainability, digitalisation, and internationalisation, providing a theoretical foundation to contextualise challenges. The findings show that companies face barriers in aligning sustainability with scalability, especially in diverse regulatory environments and optimising logistics to reduce emissions. Despite distinct business models, common challenges such as managing environmental impact, regulatory compliance, and consumer engagement are dominant.
