A new UPTAKE deliverable titled “Consolidated assessment of CDR options: Techno-economics and potentials of geological, weathering, mineralization, land-based and coastal CDR measures” has just been finalized. With this report, UPTAKE advances primary research by conducting targeted bottom-up analyses to refine carbon dioxide removal (CDR) parameterizations for use in Integrated Assessment Models (IAMs).
Previous UPTAKE work (Deliverable D2.1) highlighted that IAMs have traditionally focused on a subset of CDR options, primarily BECCS and afforestation/reforestation. In recent years, modeling efforts have progressively expanded to include technologies such as DACCS, biochar, and enhanced weathering. However, several other approaches — including ocean alkalinity enhancement, soil carbon sequestration, and blue carbon — are still in the early stages of quantitative representation. In addition, parameterizations for existing technologies needs to evolve as new techno-economic data and physical insights become available.
This report contributes to the ongoing development by conducting bottom-up assessments designed to deliver updated estimates of potential scale, cost, and effectiveness required for improved model parameterization. By generating these refined datasets and dedicated CDR modules, UPTAKE aims at ensuring that a wider variety of technologies can be systemically integrated into the modelling frameworks used to support next-generation climate policy.
Stay tuned for the report’s publication!
