Research on Integrated Assessment Models (IAMs), IPCC emissions scenario ensembles, and the appropriate use of modelling to guide climate policy and decision making, using a variety of disciplinary approaches and methods.

Ida Sognnæs holds a PhD from the Cambridge Centre for Environment, Energy and Natural Resource Governance, University of Cambridge (2020), an MA in Energy and Resources, University of California, Berkeley (2014), an MSc in Applied Mathematics and Physics, Norwegian University of Technology and Science (NTNU) (2011), and a BSc in Political Science, NTNU (2012). She has also been a visiting researcher at the University of Oxford, Institute for New Economic Thinking (2019).

Ida’s current research focuses on the use of IPCC emissions scenarios to obtain robust insights on climate mitigation, the identification of key uncertainties, assumptions, and biases, and the use of emissions scenarios by policy makers, energy companies, and the financial sector. She also works on the history of IAMs, the economics of climate change, technological change forecasting, decision making under uncertainty, ethical and political dimensions of modelling for policy, and science policy. Ida uses mixed quantitative and qualitative methods in her research.

Ida currently leads the Norwegian Research Council funded project 'StressTest: Using scenarios to assess climate risk in the financial sector'. She led the first global modelling run in the EU Horizon 2020 funded project 'PARIS REINFORCE'.


  • 4C – Climate-Carbon Interactions in the Current Century The EU-funded project 4C (Climate-Carbon Interactions in the Current Century) aims to fill the knowledge gap surrounding climate sensitivity to carbon dioxide emissions by reducing the uncertainty in our quantitative understanding of carbon-climate interactions and feedbacks.
  • StressTest: Using scenarios to assess climate risk in the financial sector Increasingly, financial decision-makers are asked to assess, disclose and respond to climate-related risks across a range of potential future scenarios. In the project StressTest, CICERO will produce scenario data and guidelines that will allow help financial actors to respond to regulatory initiatives on scenario use.
