Compliance used to be sold as a moat. It is starting to look like plumbing. The significance of the new Retailer Brand Due Diligence Questionnaire and One Retail Hub backed by ASOS, Zalando, and their peers is plain enough: due diligence in fashion is being turned into shared software.

That changes the argument. The advantage will not belong to the brand that talks most piously about values. It will belong to the operator that can ingest requirements, structure evidence, share data cleanly, and move before the next form arrives.

The facts are blunt. ASOS said on 10 February that it had joined six other retailers to launch a unified questionnaire and a free digital hub for human rights and environmental due diligence. TrusTrace’s product page says the core platform is free for brands, lets them share one submission across participating retailers, and uses AI to reuse existing documents and suggest answers. In a separate company note, TrusTrace says the assessment is 51 questions long and that early brand users are reporting a 70% reduction in workload.

Everyone else will call this a sustainability admin fix. That is too small. This is a control-layer story.

The OECD’s garment and footwear guidance is the common spine here, and the OECD notes that this sector guidance is government-backed and adopted by 50 governments. Once seven retailers agree to operationalise that baseline in one questionnaire, “good practice” starts to harden into interface. The work remains difficult. The format becomes standard.

That matters more because the rules are still moving. In February, the Council of the European Union signed off changes meant to reduce reporting burden and limit the trickle-down effect on smaller companies. Brands are still fielding overlapping due-diligence and reporting requests. Green Retail linked this launch to the EU’s wider digital product passport agenda, but the European Commission’s ESPR page and its implementation page describe a phased rollout that is still under technical preparation, not a single 2027 start date. Regulation is wobbling at the edges; the data burden is not.

Fashion media has spent the past year staring at AI interfaces. Fair enough. Chat, search, styling, checkout, all worth watching. But the substrate is where power settles. If compliance evidence becomes easier to reuse and share across retailers, then due diligence stops functioning as a branding speech and starts functioning as a shared operating system.

That will irritate some people. It should. A great many brands preferred compliance when it was expensive theater. Shared software is less romantic. It is also far more dangerous, because once the process is standardized, everyone can see who is fast, who is late, and who never built the machinery at all.
