SBTi revamps corporate net-zero standard for real-world implementation

Fashion brands that built their climate messaging on science-based targets just got a new rulebook, and it is looser in some places, stricter in others. The Science Based Targets initiative released Corporate Net-Zero Standard V2.0 on June 11, calling it its most comprehensive corporate climate-action framework to date and shifting the conversation from ambition to real-world implementation. For apparel and footwear companies already using the SBTi system, the stakes are immediate: how they measure progress, what they disclose and which promises still look credible.

The biggest change is flexibility. Version 2.0 moves to a digital standard format and adds category-based applicability rules tied to company revenue, an implementation hierarchy, a best-efforts approach and SME categorization. In practice, that gives fashion groups more room to tailor the route to net zero, especially brands with sprawling supply chains, multi-tier sourcing and uneven operations across regions. It should also make life easier for smaller companies that struggled to fit a one-size-fits-all template. But the same customization can also blur accountability if companies lean on the softer language without proving emissions cuts in the real world.

SBTi says the revision came through a broad multi-stakeholder process. The Technical Department led the work, the independent Technical Council reviewed and approved it, and the Board of Trustees formally adopted it after two public consultations, first from March to June 2025 and then from November to December 2025. The initiative says outside input informed the rewrite, but final content decisions stayed with SBTi, a useful detail for an industry that will now have to trust the guardrails as much as the flexibility.

Validation against Version 2.0 opens on February 1, 2027, after additional implementation and progress-assessment resources are released through 2026 and beyond. Existing validated targets remain valid through their current cycle, subject to the standard five-year review provisions, so companies already in the system do not need to scrap what they have built. That matters in fashion, where SBTi says more than 11,000 companies now have validated targets and it crossed 10,000 in January 2026.

The new standard lands in a sector that already relies on SBTi guidance to line up with net zero by 2050, and brands such as Chanel have held SBTi-validated long-term climate goals. SBTi says companies with validated targets have reported stronger market positioning, increased investor confidence and greater strategic cohesion, while a separate report found 91% of surveyed companies saw a positive overall business impact. That is the promise. The harder test is whether brands use the revamped framework to cut more emissions across materials, manufacturing and logistics, or simply to make the claims look neater.

Over the next 12 months, the real journalism test will be whether apparel companies show their work. Watch for clearer target-setting methods, cleaner disclosures on implementation choices and evidence that the 2027 Ongoing Emission Responsibility framework tightens responsibility instead of softening it. If Version 2.0 earns trust, it will be because fashion used the extra flexibility to move faster, not to hide.
