University of Bristol

Daniel Schien leads research in the Sustainable Computing Group at the University of Bristol, focusing on how to measure and reduce the environmental impacts of digital technologies, from AI and digital media to IoT and communication networks. His work advances environmental assessment of ICT through a systemic, long-term perspective that considers not only efficiency at the level of chips, models, and networks, but also rebound and indirect effects, infrastructure lock-in, and the organisational and policy drivers that shape impacts at scale.
