Ibstock

Recorded Carbon Result

212kgCO₂e/t

A1–A3 GWP-total per tonne of brick, from DORKET HEAD Product Group 2 (HUB-1124). The declaration is per 1 kg; this is an exact ×1000 conversion. On Ibstock's own per-m² basis (60 bricks/m² at 1.89 kg) that is about 24 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.

Indicator: GWP-total

A1–A3 covers raw-material supply, transport to manufacture and manufacturing. It is product-stage information, not a whole-life result.

* A4/A5 are EPD scenarios, not project-specific results. Module D is outside the A–C system boundary and is not added to A–C. Module nomenclature follows BS EN 15978 / EN 15804. Declared values are suitable as inputs to a whole life carbon assessment under the RICS Professional Standard (2nd edition); this panel is not an assessment.

* Includes the EPD’s A4/A5 scenario assumptions, not project-specific transport or installation. This is the aggregation the proposed Part Z applies upfront limits to. The A1–A3 figure includes declared biogenic storage of <0.001 kgCO₂e; Part Z aggregates upfront carbon excluding sequestered carbon, which is the assessor's adjustment to make.
