Energy Program of the International Institute for Applied Systems Analysis (IIASA)

Joeri Rogelj is a Research Scholar at the Energy Program of the International Institute for Applied Systems Analysis (IIASA), where he works on connecting insights from the geosciences with energy modelling and climate policy. He has published on emission scenarios, carbon budgets, climate change uncertainty, implications of near-term policy choices, and on trade-offs and synergies between air-pollution and climate policies. His current projects focus on connecting the natural sciences to the policy realm, and include the study of extremely low emission scenarios, the simultaneous achievement of multiple sustainability objectives, and the exploration of approaches that can foster integration of knowledge across disciplines.


Joeri holds a PhD in climate science from ETH Zurich, Switzerland, and Master's degrees in Engineering and Development Studies from KU Leuven, Belgium. Before joining IIASA, he held research positions at the Potsdam Institute for Climate Impact Research (PIK, Germany) and as a post-doctoral researcher at ETH Zurich. Furthermore, his professional experience includes three years as a project engineer in the field of rural electrification and drinking water systems in Rwanda (Africa), among further stays in Colombia and Denmark.

Web tools and Projects we developed

  • Open-NEM

    The live tracker of the Australian electricity market.

  • Paris Equity Check

    This website is based on a Nature Climate Change study that compares Nationally Determined Contributions with equitable national emissions trajectories in line with the five categories of equity outlined by the IPCC.

  • liveMAGICC Climate Model

    Run one of the most popular reduced-complexity climate carbon cycle models online. Used by IPCC, UNEP GAP reports and numerous scientific publications.

  • NDC & INDC Factsheets

    Check out our analysis of all the post-2020 targets that countries announced under the Paris Agreement.
