Recorded Carbon Result
A1–A3 GWP-total per tonne of brick, from BIRTLEY Product Group 1Bi (HUB-6078). The declaration is per 1 kg; this is an exact ×1000 conversion. On Ibstock's own per-m² basis (60 bricks/m² at 2.64 kg) that is about 40.4 kgCO2e/m² of wall. The figure is the product group's, not a measurement of this colour alone — bricks in a group share a recipe and kiln.
