Claire Fyson
Team Leader Mitigation Pathway Analysis
Email

Claire joined Climate Analytics in 2016 and is now the Co-Head of the Climate Policy Team and leads the Mitigation and Modelled Pathways analysis group. Her work includes assessing NDC ambition and working with modelled pathways that are consistent with the Paris Agreement’s 1.5°C warming limit. She has contributed to Climate Action Tracker and 1.5°C National Pathways Explorer, focusing in particular on net zero targets, the role of carbon dioxide removal and mitigation options in the land sector. She has also published peer-reviewed literature on these topics.
Throughout her time at Climate Analytics, Claire’s work has bridged the Climate Policy, Science and Climate Diplomacy teams, including by providing scientific support to Small Island Developing States during negotiations under the IPCC and UNFCCC.
Before joining Climate Analytics, Claire worked for the Potsdam Institute for Climate Impact Research (PIK) in the PRIMAP Emissions Team, where her work centred on analysing the mitigation components of the INDCs, with particular focus on the land-use sector. She has also worked as a policy analyst in a sustainability consultancy in London (the Carbon Trust), mainly focusing on renewable energy.
She holds an MSci in Natural Sciences from the University of Cambridge, with a specialty in geological sciences, and an MSc in Environmental Change and Management from the University of Oxford. Before joining PIK, she also did a traineeship in the European Commission, working in the energy and environment unit of the Secretariat General.
