PolyAl in CSRD reporting: double materiality, ESRS E1 and ESRS E5
How EU companies should treat PolyAl-related procurement and product-design choices in their CSRD double-materiality assessment.

The Corporate Sustainability Reporting Directive (CSRD) and the European Sustainability Reporting Standards (ESRS) require listed and large EU companies to report on environmental impacts using a double-materiality approach. PolyAl procurement and product-design choices touch ESRS E1 (Climate change), ESRS E5 (Resource use and circular economy) and ESRS S2 (Workers in the value chain) directly.
What double materiality means
A topic is material if it is financially material (affects company value) or impact-material (the company has significant positive/negative effects on people or environment), or both. Both directions must be assessed.
ESRS E1 — Climate change
Relevant disclosures touching PolyAl:
- E1-4 Targets related to climate change mitigation
- E1-5 Energy consumption and mix
- E1-6 Gross Scopes 1, 2, 3 GHG emissions and total
- E1-7 GHG removals and GHG mitigation projects
For a manufacturer using PolyAl in pallets or street furniture: report the avoided Scope 3 emissions versus a virgin HDPE baseline. Methodology: ISO 14064-2.
ESRS E5 — Resource use and circular economy
Directly relevant:
- E5-1 Policies related to resource use and circular economy
- E5-2 Actions and resources to circular economy
- E5-3 Targets to circular economy (e.g. % recycled content)
- E5-4 Resource inflows (mass of recycled content procured)
- E5-5 Resource outflows (mass recovered at end of life)
A company purchasing PolyAl reports under E5-4: tonnes of post-consumer recycled material entering the operational boundary, with reference to production following UNE 53925:2026.
ESRS S2 — Workers in the value chain
If using PolyAl from a known recycler with traceable supply chain, report on labour conditions in upstream waste collection and processing — usually a positive narrative for European operations.
The supplier's role
Good PolyAl suppliers provide:
- Per-batch CoA with PCR %, density, MFI, ash, mechanicals
- kg CO₂e/kg per batch, cradle-to-gate, ISO 14040/14044
- Audit-ready mass-balance documentation
- ISO 9001 / ISO 14001 certificates
- REACH and RoHS compliance statements
- Origin of feedstock (carton recycler, country)
With this pack, the buyer can drop the data straight into ESRS E1 and E5 disclosures.
Pitfalls to avoid
- Greenwashing: never claim "100 % recycled" if the actual PCR is 80 %
- Double counting: do not also try to monetise as carbon credits what you reported in Scope 3
- Unverified suppliers: insist on third-party-audited recyclers
For any EU company under CSRD scope (or about to be), PolyAl is one of the simplest, most defensible circular-economy levers available in 2026.
