Wienerberger Kingsbury Brickworks
The 12 clay bricks Wienerberger make at Kingsbury Brickworks, extruded formed — Staffordshire Smooth Blue, Staffordshire Blue Dragface, Blue Wirecut Engineer, Red Class B and others. Wienerberger declare by works rather than by brick, so every brick from this site shares one figure: 234 kgCO₂e per tonne. Across their ten UK works that figure runs from 183 to 398 — a factor of 2.2 inside one company, set mostly by how the brick is formed rather than by the clay.

Recorded Carbon Result
A1–A3 GWP-total per tonne, for every brick made at Kingsbury Brickworks — Wienerberger declare by works, so the 12 bricks from this site share one figure. GWP-fossil is 234. Across their ten UK works the range is 183–398 kgCO2e/t, and the biggest single driver is the forming process: soft-mud stock bricks run far higher than extruded ones, most starkly at Hartlebury where the two lines on one site declare 398 and 206.
