Evidence Base
No declaration yetIbstock has not published an EPD or a quantified carbon figure for this product, so nothing on this card is numerical. The guidance below is qualitative — drawn from the product record and curated category knowledge — for early design discussion, not for figures.
Ibstock's published EPD library was checked on 2026-08-06 and contains no declaration covering this product code. Their ~33 product-group declarations cover the Ashdown, Birtley, Cattybrook, Chailey, Chesterton, Dorket Head, Eclipse, Leicester, Lodge Lane, Parkhouse and Throckley factories; this brick is not among the product codes they list. No figure has been borrowed from another group — bricks differ by recipe and kiln, so a neighbouring factory's number would be a wrong number, not an approximation.
Next step: request a current product EPD or manufacturer carbon declaration.
