Dr Catrin Harris researches Carbon Dioxide Removal (CDR) within Integrated Assessment Models (IAMs), working primarily with the IMAGE model, as part of the Carbon Direct and UPTAKE projects. She is based at the Copernicus Institute of Sustainable Development, in collaboration with PBL Netherlands Environmental Assessment Agency.
Her work focuses on the future role of CDR in global mitigation pathways. While CDR is increasingly recognised as important for limiting global warming to below 1.5 °C, the scale, type, and regional distribution of future deployment remain highly uncertain. Catrin investigates how novel CDR technologies are deployed across regions under different global carbon price trajectories, and how competition for land, energy, and other resources shapes these outcomes.
Her research advances the representation of CDR in IAMs by incorporating emerging options such as enhanced rock weathering and biochar, and by updating technology assumptions to reflect contemporary costs, performance data, and realistic growth constraints. Her findings highlight regional challenges in co-deploying multiple CDR technologies and show that the diversity of CDR portfolios correlates strongly with carbon price levels. This work supports more targeted policy and investment strategies that align regional capabilities with carbon removal goals.
