Blockleys

Name: Blockleys
Brand: Michelmersh

Shropshire extruded bricks and pavers, and the lowest-carbon works in the Michelmersh group at 226 kgCO₂e per tonne. Its declared variation is also the tightest of the four, at under 1.5% — a sign of a consistent, well-controlled process.

Recorded Carbon Result

226kgCO₂e/t

A1–A3 GWP-total per tonne of brick. GWP-fossil is 227. For scale, UK independents in this catalogue run from −15.4 (an unfired earth block) through 106 for a wood-fired brick to 697 for a Hoffman-kiln handmade one — "clay brick" is not one number, and the firing route is what sets it.

Indicator: GWP-total

Blockleys (HUB-6021)

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

* EPD transport and installation scenario, not this project's. Not declared: site, use. Module D shows potential impacts or benefits from reuse, recovery or recycling after the product's assessed life. It is reported separately and never added to A-C. Do not compare bar lengths between materials. Each chart may use a different scale and declared unit.

* 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.

Service Life — the B4 Replacement Input

150 years · EPD reference service life

The declaration states a 150-year reference service life.

≈1 installation over a 60-year building study period.

B4 (replacement) follows the building, not the product: an assessor multiplies replacement cycles by project quantities. This record supplies the service life and does not compute B4.
