# 2025 Enabling Carbon-Aware Networks |
|
Wired networks consume vast amounts of electricity, but not all energy is equally clean. This work introduces carbon-aware approaches that reduce emissions by adjusting how data is routed, scheduled, and stored based on the carbon intensity of the energy available in each region. It also enables precise tracking of emissions for individual data flows. These methods help internet providers and content platforms cut emissions without added cost, offering a practical path to greener digital infrastructure
Sawsan El Zahr is a fourth year PhD student within the Computing Infrastructure Group at the University of Oxford. Her current research focuses on reducing the carbon footprint of computer networks. Her focus is on carbon emissions, rather than energy consumption alone, and her research combines routing algorithms, power modelling, and net-zero solutions. Sawsan is a recipient of the Oxford-Qatar-Thatcher scholarship and a titular Clarendon scholarship. Her research has earned her several awards, including the Dyson Award for Outstanding Research at STEM for Britain 2024 and the Applied Networking Research Prize (ANRP) issued by IRTF.more
