Abstract
The substitution of material-based services with digital services—for example films or music—alters the environmental impact of our everyday activities and shifts visible material use to less visible digital services. A holistic life cycle assessment (LCA) of digital transformation requires the assessment of information and communication technology (ICT) with its wide range of multifunctional devices as well as substitution and summation effects caused by new services enabled by modern ICT. The 73rd Discussion Forum on Life Cycle Assessment (DF LCA) was held on 21 November 2019 to discuss the environmental implications of digital transformation in view of the effective as well as the potential environmental impacts. While currently being a small but already relevant contributor to the overall greenhouse gas emissions, the relevance of the ICT sector is predicted to grow rapidly within the next 5 to 10 years (Belkhir & Elmeligi, 2018). This 1-day forum offered the possibility to discuss current as well as potential future implications of devices as well as digital services on the environment.
