Pushing the model boundary: developing the approach to integrated assessment modelling

Steve Pye, UCL

Integrated assessment models form a large part of the evidence base feeding into the IPCC process, and other domains using global scenarios. However, there are persistent questions as to the adequacy of much of this modelling, both in terms of the models themselves but also how they are being used. In this talk, drawing primarily from UCL’s research, Steve will reflect on the modelling of global scenarios, the approaches taken, and how researchers have sought to address the limitations of their models. From this talk, the emerging issue for discussion will be how the modelling community, across disciplines, can work together to inform action to drive energy system decarbonisation.

About the speaker

Steve Pye is a Professor of Energy Systems at the UCL Energy Institute, University College London (UCL), and its Deputy Director. Steve has over 18 years’ research experience on energy and climate modelling and policy analysis. His research concerns the challenge of energy system decarbonisation, using different whole system energy modelling approaches, with a particular focus on scenario modelling of national and global low carbon pathways, uncertainty assessment, and the equity and health dimensions of energy transitions. Steve’s research track record is reflected in over 60 peer review journal articles and numerous technical reports and papers. His current research projects include the FCDO-funded programme Climate Compatible Growth, the Horizon Europe DIAMOND project, and UKRI’s Energy Demand Reduction Centre. Steve gained a PhD in Energy Engineering from University College Cork (UCC) in 2019 with a thesis titled ‘Innovative approaches to developing deep decarbonisation strategies.’
