Supervisors: Mikael Johnsson - Mälardalens University, Mikael Steinar & Paulina Wilhelmsson - Case Company Aim: The aim of the study is to explore if and how acompany within the industrial electronics industry could be supported by supply chain mapping in complying with EU's ESRS regulation. Research Question: How can supply chain mapping support an industrial electronics company in complying with EU's ESRS regulation? Methodology: The methodology of this study employs a qualitative research approach, specifically using a case study to explore the implementation of supply chain mapping within an industrial electronics company for EU's ESRS compliance. Adopting an abductive framework, the research intertwines theoretical exploration and empirical data collection. Literature was reviewed from academic journals and industry reports, while empirical data was gathered through comprehensive supply chain mapping, questionnaires, and a series of interviews, including semi-structured and individual discussions. Conclusion: The study concludes that supply chain mapping is a pivotal tool for aiding an industrial electronics company in complying with the EU's ESRS regulation. It was found that comprehensive mapping of the supply chain not only helps in identifying relevant ESRS topics across the value chain but also enhances risk management and visibility. The application of supply chain mapping demonstrated significant potential for improving operational efficiency and regulatory compliance.
