Roadmap to Zero Programme

ZDHC MRSL V4.0

Today, we launch the ZDHC MRSL V4.0! 

With 16 new substances, updated chemical restrictions, formulation limits, and analytical testing, the updated ZDHC MRSL supports the ZDHC community in achieving the highest standards for sustainable chemical management.

Reminder: 30 November Deadline for Wastewater & Sludge Guidelines V1 Data Submissions 

The current wastewater reporting cycle has been extended by one month to support the transition to the ZDHC Wastewater & Sludge Guidelines V2.

Key dates to remember:

• 30 November 2026: Final deadline for uploading data under the Wastewater & Sludge Guidelines V1. Existing V1 On-site App projects can still be finalised, but no new V1 projects can be initiated.

• 1 December 2026: All wastewater test reports uploaded to the ZDHC Gateway and On-site App projects must comply with the Wastewater & Sludge Guidelines V2.

Please note: The usual 45-day reporting window cannot extend beyond 30 November 2026. After this date, you can no longer upload data under the Wastewater & Sludge Guidelines V1.
