New IVL report provides a methodological framework for quantifying lime recarbonation

EuLA is pleased to announce the publication of a new independent report developed by IVL Swedish Environmental Research Institute, providing a scientifically robust framework for quantifying CO₂ uptake through lime recarbonation across different applications.

Recarbonation is a natural chemical process through which lime-based materials reabsorb CO₂ during their use and end-of-life, permanently binding it as calcium carbonate. While this process is well established scientifically, its quantification requires methodologies that account for the diversity of lime applications and the availability of reliable data. The IVL report addresses this challenge by proposing a tiered methodological approach, enabling CO₂ uptake to be estimated using different levels of application-specific information, while ensuring transparency, consistency and scientific robustness.

Supporting international carbon accounting methodologies. The publication comes at a particularly relevant time, as the IPCC advances its work on the 2027 Methodology Report on Carbon Dioxide Removal Technologies, Carbon Capture Utilization and Storage (CDR/CCUS).

The IVL report provides an important scientific and methodological reference for discussions on how lime recarbonation can be appropriately quantified and reflected in greenhouse gas accounting.

Together with the existing scientific literature, this work reinforces EuLA’s commitment to promoting accurate, transparent and science-based recognition of lime’s full carbon cycle
