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

Environmental Product Declaration

EPD recorded

Coverage: Representative product
Declared unit: 1 m³
Programme: EPD International AB — The International EPD System
Registration: EPD-IES-0010542:004 (S-P-10542)
Standard: EN 15804+A2
Valid until: 2030-12-15
Verification: Third-party verified

Declared per 1 m³ (density 680 kg/m³); for a per-m² figure multiply by board thickness in metres. GWP-total A1–A3 is negative because EN 15804+A2 counts the biogenic carbon stored in the timber.

* EPD transport and installation scenario, not this project's. Not declared: 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.

* 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 -1130 kgCO₂e; Part Z aggregates upfront carbon excluding sequestered carbon, which is the assessor's adjustment to make.

Service Life — the B4 Replacement Input

100 years · EPD reference service life

The declaration states 100 years as a minimum rather than an expected figure, for a board installed properly with low or moderate moisture exposure.

≈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.

Comparison Status

The record contains the basic metadata required for a controlled comparison. Products must still perform the same function and use compatible units, PCRs and lifecycle scope.

Design & Specification Notes

Qualitative notes for early design discussion. Not product-specific EPD evidence, and not a basis for numerical comparison.

Finnish birch plywood in cross-bonded veneers, valued for its strength-to-weight, clean edge and pale, even face.

Typical Uses

•Interior wall cladding
•Warm feature panels
•Lobby accents

Key Performance

High load-bearing capacity for primary structure.

Specification Actions

•Confirm FSC or PEFC certification for all timber products.
•Request chain-of-custody documentation from supplier.
•Confirm the current EPD covers the selected product, finish and manufacturing route.

Indicative Health & Indoor Air

low Risk

Birch plywood; verify formaldehyde emission class (E1/E0) per product for interior air quality.
