Sustainability and digital transformation are both important and highly relevant megatrends. The convergence of digital transformation and sustainability transformation is referred to as the twin transformation. Digital transformation can serve as a catalyst to drive sustainability transformation. We categorize Supply Chain (SC) digital technologies into four Digital Concepts (DCs): Infrastructure, Engineering Technology, Data Technology, and Communication Technology. We conduct a systematic literature review, analyzing 43 full-text articles to identify the key DCs that impact SC sustainability based on the triple bottom line framework. We provide an in-depth analysis of the DCs and their role in shaping sustainability within the SC. By clustering relevant technologies into DCs, this study finds that most of these digital technologies have a positive overall impact on sustainability.
