Dr Joeri Rogelj is Director of Research at the Grantham Institute and Reader in Climate Science & Policy at the Centre for Environmental Policy at Imperial College London. He explores how societies can transform towards more sustainable futures. His interdisciplinary research connects Earth system sciences to the study of societal change and policy.

Over the past decade, Joeri Rogelj has contributed to major scientific climate change assessments informing international climate policy. He is a long-serving lead author on the annual Emissions Gap Reports by the United Nations Environment Programme (UNEP). He contributed to the Fifth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC), served as a Coordinating Lead Author on mitigation pathways for the IPCC Special Report on 1.5°C of Global Warming, and as a Lead Author for the IPCC’s Sixth Assessment. He continues to follow the negotiations under the UNFCCC and was in 2019 the youngest member serving on the UN Secretary-General's Climate Science Advisory Group

He has published on the potential effectiveness of international climate agreements including the Copenhagen Accord and the Paris Agreement, carbon budgets, the urgency of climate mitigation action, global net zero emission targets, the interaction between climate and sustainable development, emission pathways that limit global warming to 1.5°C and 2°C, and climate justice.

Joeri Rogelj holds a PhD in climate science from ETH Zurich, Switzerland, and an MSc in Engineering and a postgraduate degree in Cultures and 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 Senior 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.

Joeri Rogelj was awarded the 2021 Early Career Scientist Award (Europe) Award from the International Science Council for exceptional contribution to science and international scientific collaboration by an early career researcher. In 2016, he was awarded the inaugural Piers Sellers Award for his world-leading contributions to solution-focused climate research. In 2014 he received the ETH Medal for his outstanding doctoral dissertation, and in 2011 he received the Peccei Award for outstanding research by a young scientist. Since 2019, he has been a Web of Science Highly Cited Researcher representing the top 1% impactful researchers in the field of Energy & Environment.
