Dimitrios Pappas is a Lecturer in Sustainability in the School of Mechanical and Aerospace Engineering at Queen’s University Belfast. His work sits at the intersection of climate policy, energy economics, and industrial decarbonisation, and asks how the transition to net zero can be measured, financed, and governed in practice.
His research is organised around three themes: net-zero energy systems and emissions accounting; the circular economy and industrial transformation; and the environmental footprint of artificial intelligence and digital infrastructure, an emerging source of energy demand that conventional climate accounting largely fails to capture. Methodologically, he combines emissions and energy accounting, including index decomposition and lifecycle approaches, with the analysis of business models and finance for low-carbon systems.
He completed his PhD at the University of East Anglia in 2020 and held post-doctoral positions at the University of Manchester and UEA, contributing to the INTERREG F(C)A CIRCLE project, to the EnergyREV, and Intelligent Community Energy (ICE) programmes. His publications span the carbon consequences of shifting global production (Applied Energy), business models for smart and local energy systems, and circular-economy interventions across the built environment, transport, and food sectors.
