Quantifying Textile Residual Liability Under ESRS E5-5 and E1-6: A Dual-Metric Framework for Permanent Residual Liability and Scope 3 Category 12 Disclosure

The European Sustainability Reporting Standards (ESRS), established under CSRD (Directive 2022/2464/EU, implementing Regulation (EU) 2023/2772) and as revised by the Omnibus Simplification Directive (Omnibus I, entered into force 18 March 2026), require fashion and textile companies to disclose two figures that the industry has not previously been required to compute: the Permanent Residual Liability (PRL) under ESRS E5-5, expressed in metric tonnes, and the associated Scope 3 Category 12 greenhouse gas emissions under ESRS E1-6, expressed in tCO₂e. The Omnibus reduced reporting scope; it did not modify the ESRS E5-5 or E1-6 metrics. This working paper presents a dual-metric framework for computing and disclosing both obligations from a common input dataset.

Section 1 sets out the regulatory context: the Corporate Sustainability Reporting Directive (CSRD), ESRS E5-5, ESRS E1-6, and the three distinct disclosure obligations created for textile undertakings.

Section 2 defines the Permanent Residual Liability — the physical mass of products placed on market that will not be recovered at end of life — and introduces the mass-balance methodology and fibre-type classification system used to compute it.

Section 3 presents the Scope 3 Category 12 emission model across seven end-of-life pathways: natural fibre landfill decomposition, synthetic fibre landfill and incineration, certified industrial composting (a near-zero pathway for protein fibres including wool), open burning, per- and polyfluoroalkyl substances (PFAS) contamination, persistent synthetic polymer contamination, and the emerging pathway of fungal biodegradation of synthetic fibres.

Section 4 maps the framework to three ESRS disclosure obligations — ESRS E5-5 (PRL in tonnes), ESRS E1-6 (Cat.12 in tCO₂e), and ESRS E5-2 (compensatory investments) — and establishes that these obligations are unit-incompatible and must not be consolidated.

Section 5 establishes a non-compensability rule — PRL cannot be offset, neutralised, or compensated by any financial instrument, carbon credit, or nature-based investment — and defines two operative pathways through which brands can genuinely reduce their future PRL figure: Pathway 1, modification of future fibre composition toward certified biodegradable alternatives (EN 13432, ASTM D6400, BPI, or equivalent); and Pathway 2, certified closed-loop chemical recycling achieving a minimum 50% closed-loop content rate, meeting EU EPR requirements, GRS certification, and ISO 14025 standards. A third near-zero-emission end-of-life route — certified industrial aerobic composting — is identified for protein-based fibres including wool.

Section 6 proposes five eligibility criteria for compensatory investment verification under ESRS E5-2, providing an auditor-defensible standard for nature-based solution disclosures in the textile sector.

Section 7 addresses implementation considerations including data quality, third-party assurance, and jurisdiction-specific parameters.

Section 8 concludes with the disclosure chain from individual garment to CFO-signed sustainability report.
