Purpose <p>Using digital technologies to support life cycle assessment analysis guarantees more reliable results and data verifiability, allowing data traceability within and between supply chains. However, digital technologies, considered supporting tools to improve energy efficiency and optimise the use of natural resources, themselves consume resources and energy. No study provides a comprehensive review of the existing literature on how digital technologies could enhance life cycle assessment studies. The present study aims to deepen the environmental impact of digital services and identify how and which digital technologies can support and contribute to life cycle assessment studies, providing a roadmap for future research.</p> Method <p>Starting from this research gap, a systematic literature review has been developed to summarize existing evidence on digital technologies and life cycle assessment studies. The authors analyze 29 papers published between 2002 and 2024, identifying the bibliometric characteristics and classifying the works into two main themes.</p> Results and discussion <p>The results show that digital technologies aim to improve the quality of carbon emissions data to achieve the goals of net zero carbon emissions and positive carbon emissions, thus underlining that digitalization is linked to the collection, management and archiving of data of a product during its life cycle, on the other hand, highlight the pollution generated by the life cycle of electronic devices or by the energy consumed by all the infrastructures used for data storage and transfer around the world. In general, the need to adequately evaluate the impacts of digital technologies emerges, as well as the need to adopt valid tools capable of achieving this objective.</p> Conclusions <p>The study highlights future research trends and represents a starting point for researchers who wish to contribute to developing this line of research. Digital technologies can support companies by streamlining production processes, collecting and generating secure and reliable data, and ensuring traceability within and between supply chains and the reliability of information produced by data analytics. However, it is essential to adopt design thinking to manage energy consumption effectively during the design phase. In conclusion, the conscious adoption of e-services and promoting circular economy practices for electrical and electronic equipment are essential to ensure sustainable development in different sectors.</p>
