We back every tonne of CO₂ that we remove using direct physical measurements where available, supplemented by measured activity data and established emission factors.
We track CO₂ using precise mass-flow measurements at the inlet and exhaust of the reaction chamber. Our calculations also account for CO₂ losses from void space that may occur during material discharge. To determine the grey emissions, we measure the electricity consumption of our liquefaction and storage plants, plus the amount and distance of CO2 transported, alongside embodied emissions from plant construction and a buffer for natural carbonation.
All of this data is automatically monitored and logged by our digital tracking platform, so we know exactly how much CO2 we've removed at any point in time.
