Mineral carbonation in reactive bedrock offers a rapid and permanent method for carbon dioxide (CO₂) sequestration, converting CO₂ into stable mineral phases within a geologically short timeframe. This study presents the first-ever systematic assessment of onshore CO₂ mineral storage potential in Sweden, based on fieldwork, sampling, and mineralogical and geochemical analyses conducted at 23 localities. While this theoretical assessment cannot resolve uncertainties related to reactivity, dissolution capacity, and sequestration efficiency, it provides a critical foundation for identifying potentially favorable storage reservoirs.
