Wienerberger Denton Brickworks
The 29 clay bricks Wienerberger make at Denton Brickworks, extruded formed — 65mm Class B Eng Denton, Peak Bordeaux Blend, Woodland Mixture, Crofters Medley and others. Wienerberger declare by works rather than by brick, so every brick from this site shares one figure: 229 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.

Carbon and evidence
Product Evidence
Evidence currently held for the Wienerberger product record.
Recorded Carbon Result
A1–A3 GWP-total per tonne, for every brick made at Denton Brickworks — Wienerberger declare by works, so the 29 bricks from this site share one figure. GWP-fossil is 229. 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.

Keyed on the brickworks, not a single product — averaged over "multiple products", data year 2022. The works→brick mapping comes from Wienerberger's own EPD Summary Document, which is the only published source for it (product pages carry no factory field). Covers 29 named bricks: 65mm Class B Eng Denton, Peak Bordeaux Blend, Woodland Mixture, Crofters Medley, Chepstow Multi, Old Eccleston Blend, Leamington Buff Multi, Sahara Buff, Kinder Mixed Red, Peak Mixed Red 50/50/mix, Rothesay Blend, Windmill Golden Multi, Windmill Orange Multi, Dartmoor Heather, Northgate Blend, Oakwood Multi, 65mm Swarland Pink, 65mm Swarland Autumn Brown, 73mm Old Weatherfield Blend, 73mm Russett, 73mm Class B Eng Denton, 73mm Pinhole Dark, 73mm Damson Pinhole, 73mm Pinhole Multi, 73mm Godiva Red Sandfaced, 73mm Godiva Multi Sandfaced, 73mm Swarland Autumn Brown, 73mm Swarland Golden Thatch, 73mm Swarland Red Sandfaced. The declaration narrative mentions 30 facing bricks plus 2 Class B engineering (32) while the summary lists 29 — the published list is a subset, so a brick absent from it is not proof it is made elsewhere.
