## Summary

Compare WPC environmental declarations only on a consistent function, quantity and life-cycle scope. An EPD is an information source, not a simple green approval label.

## Practical method

Check that the declaration covers the product and manufacturing route actually offered, and verify its validity and programme details. Align declared units, assessment rules and included life-cycle stages before comparing figures. For an illustrative terrace comparison, include the supporting system and replacement assumptions if they differ materially between options. Do not compare a kilogram of one product directly with a square metre of another. Record uncertainty and avoid declaring one option environmentally superior from a single unmatched number.

## Planning and verification

Compare complete systems for the stated use, including supporting structure, connections, drainage and maintenance access. Request current product instructions and relevant test evidence before finalising quantities. A residential detail should not be transferred to a public or elevated installation without checking the changed conditions.

## Handover and maintenance

Record the selected profile, batch, approved drawings and maintenance owner. Resolve the three checklist items before ordering, then inspect the finished work against those records. Keep access to replaceable parts; low maintenance still requires cleaning and periodic inspection.

## Comparison

Design check | Evidence to record
Matched product and unit | Show the requirement on the project drawing
Aligned life-cycle scope | Obtain applicable product or design evidence
Recorded comparison assumptions | Assign installation and maintenance responsibility

## Comparing environmental product declarations for WPC — What should be confirmed before ordering?

Compare WPC environmental declarations only on a consistent function, quantity and life-cycle scope. An EPD is an information source, not a simple green approval label. Confirm the three project checks below with the supplier and the responsible designer. A sample establishes appearance, not approval of the complete installation. Matched product and unit; Aligned life-cycle scope; Recorded comparison assumptions
