EuLA factsheet on lime recarbonation.

The 33%: the overlooked part of lime’s carbon cycle.

Around one third. Within one year.

Research shows that, across major lime applications, lime-based products can reabsorb around one third of lime’s process CO₂ emissions within the first year of use.

The chemistry is straightforward: CO₂ reacts with lime and becomes calcium carbonate — a stable mineral form.

This does not replace the need to reduce and capture emissions at the kiln. But it does show why looking only at the production stage gives an incomplete picture of lime’s carbon cycle. Accurate climate accounting should reflect the full chemistry. Understanding the full cycle starts with understanding the chemistry.
