New assessment criteria, redefined performance levels and a stronger focus on continuous improvement. With Supplier to Zero V2, ZDHC introduces an updated framework to assess the maturity of chemical management practices at manufacturing facilities.
The ZDHC Roadmap to Zero Programme continues to evolve with Supplier to Zero Version 2, published on 31 July 2026 and set to become mandatory from 1 February 2027.
This update marks a significant shift: the level achieved by a facility no longer indicates the degree of verification of the assessment, but rather the actual maturity of its chemical management practices.
For brands and suppliers in the textile, leather, apparel and footwear sectors, this new approach strengthens the connection between ZDHC requirements, operational performance and supply chain management.
Supplier to Zero V2: What’s changing?
The new version introduces a more structured assessment framework, aligned with the Suppliers Roadmap to Zero and organised around three key areas:
INPUT: purchasing, selection and traceability of chemicals and incoming materials.
PROCESS: chemical management within manufacturing processes, safety, operational procedures and continuous improvement.
OUTPUT: monitoring of wastewater, sludge, emissions and waste management.
Key updates also include the introduction of mandatory performance criteria, increased attention to material traceability and assessment requirements differentiated according to facility characteristics.
The aim is to make assessments more representative of the practices actually implemented, supporting measurable continuous improvement over time.
Three performance levels, new assessment methods
With V2, Supplier to Zero distinguishes between a facility’s maturity level and the method used to verify it.
The programme establishes three progressive performance levels:
| Level | Description |
|---|---|
| Level 1 – Baseline | Focuses on fundamental requirements. |
| Level 2 – Advanced | Recognises more structured chemical management practices. |
| Level 3 – Best Practice | Recognises advanced and systematic implementation. |
Three assessment methods are also defined: self-assessment, third-party document review (desktop assessment) and third-party on-site assessment.
This distinction allows the performance achieved and the reliability of the assessment to be reported separately, providing brands and suppliers with clearer and more comparable information.
Transition timeline
ZDHC has established a transition period to allow manufacturing facilities to familiarise themselves with the new framework.
From 1 August 2026 to 31 January 2027, both V1 and V2 remain available. Starting 1 February 2027, all new assessments must follow the V2 requirements.
Certificates issued under V1 before this date will remain valid until their scheduled expiry date.
For suppliers, this transition period provides an opportunity to assess their level of readiness and identify potential areas for improvement. For brands, it is an important time to understand how the new framework will affect the evaluation of chemical management performance across their supply chains.
How to prepare for Supplier to Zero V2
The transition to the new version requires a comprehensive approach to chemical management systems, taking into account the chemicals used, internal procedures, documentation and environmental monitoring activities.
