Climate change with global warming represents one of the most significant challenges of our times. Achieving the objective of the Paris Agreement and limiting global temperature increase to 1.5 °C requires greenhouse gas emissions to decline to net zero by the middle of this century followed by negative emissions. CCUS (Carbon Capture Utilisation and Storage) is identified as one of several key technologies to reach this climate goal.

The CO2Crete project aims to develop a technical infrastructure and methodology for evaluating the potential for CO2 storage in alkaline-rich residues/waste materials available in Sweden such as metallurgical slags, boiler ashes, concrete products, and mine tailings.

The CO2Crete project is carried out at RISE Research Institutes of Sweden during the period 2023–2026 with support from the Swedish Agency for Economic and Regional Growth and the EU from the Just Transition Fund. The support relates to the National Programme for the Just Transition Fund 2021–2027. The Just Transition Fund is an EU fund that focuses on the industries and counties with very high carbon emissions. The fund aims to reduce emissions and tackle the challenges associated with the transition.
