The Scope 3 Water Playbook
In 2026, Scope 3 water risk is no longer optional. With converging mandates from the CSRD/ESRS E3, TNFD (LEAP framework), and California SB 261-the "Big Three"-corporates face mandatory disclosure of upstream and downstream water impacts. Yet most organizations struggle with incomplete supplier data, unreliable proxies, and fragmented reporting.
The Scope 3 Water Playbook is the practical, step-by-step guide that closes these gaps and turns compliance into competitive stewardship.
Written by Dr. Si Mokrane SIAD, this 164-page playbook combines regulatory clarity, advanced technical methods, and proven implementation frameworks to help sustainability teams deliver accurate, audit-ready Scope 3 water disclosures-fast.
Why this playbook is different- Three tailored reading tracks-Executive (strategic risks & governance), Technical (remote sensing & hydrological modeling), and Implementation (supplier engagement & 90-day roadmaps)-so every role finds exactly what they need.
- Deep coverage of the "Big Three" frameworks plus alignment strategies for maximum disclosure efficiency.
- Hands-on tools: workshops, checklists, RACI templates, maturity models, and technology stack recommendations.
- Advanced yet accessible methods: WRI Aqueduct integration, Copernicus/Sentinel-2 workflows, NDWI/NDVI indices, ISO 14046/AWARE weighting, and proxy estimation techniques.
- Real-world focus on priority locations, compelled buyers, and supplier data collection in high-risk basins.
- Chief Sustainability Officers and ESG leaders preparing for 2025-2028 mandatory reporting
- Water stewardship and supply chain professionals needing actionable data strategies
- Technical teams seeking cutting-edge remote sensing and modeling approaches
- Consultants and auditors supporting corporate water risk assessments
