Dr Joeri Rogelj is Lecturer in Climate Change and the Environment at the Grantham Institute at Imperial College London. His research aims at actively informing the international climate policy debate through dedicated interdisciplinary research and analysis, and focusses on the scientific assessment of international climate agreements, the identification and response to major gaps in knowledge for effective climate policy, and the development of new concepts bridging the divide between social and physical sciences.

Over the past decade, Joeri Rogelj has contributed to and led several major scientific climate change assessments informing the international climate negotiations under the UNFCCC. He is a long-serving lead author on the Emissions Gap Reports; these are annual policy synthesis reports by the United Nations Environment Programme (UNEP). He contributed to the physical science and climate change mitigation assessment of Fifth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC), is a Coordinating Lead Author for the IPCC Special Report on 1.5°C of Global Warming, and a Lead Author on carbon budgets for the IPCC’s Sixth Assessment. He also continues to follow the UNFCCC climate negotiations as a scientific advisor.

He has published on the potential effectiveness of international climate agreements including the Copenhagen Accord and the Paris Agreement, carbon budgets, implications of delaying climate mitigation action, the mitigation potential of short-lived climate forcers, global zero emission targets, the interaction between climate and sustainable development, the appropriateness of global temperature targets like 2°C, and emission pathways that limit global warming to 1.5°C and 2°C.

Joeri Rogelj holds a PhD in climate science from ETH Zurich, Switzerland, and a Master's degree in Engineering and a postgraduate degree in Development Studies, both from KU Leuven, Belgium. Before joining the Grantham Institute, he held research positions at the Potsdam Institute for Climate Impact Research (PIK, Germany), as a post-doctoral researcher at ETH Zurich, and as a Research Scholar at the International Institute for Applied Systems Analysis (IIASA, Austria) with whom he continues to collaborate. His professional background further includes three years as a project engineer in the field of rural electrification and drinking water systems in Rwanda.

In 2011 he received the Peccei Award for outstanding research by a young scientist, and in 2014 he received the ETH Medal for his outstanding doctoral dissertation. In 2016, he was awarded the inaugural Piers Sellers Award for his world-leading contributions to solution-focused climate research.
