Alliance for Water Stewardship (AWS)

What Alliance for Water Stewardship (AWS) does

Alliance for Water Stewardship (AWS) is a global, multi-stakeholder membership alliance that develops and operates the International Water Stewardship Standard, an auditable framework for farms, factories and other water-using sites to understand their water use and take verifiable, third-party-assured action on shared water challenges. The organisation is registered as a Scottish Charitable Incorporated Organisation (SCIO), headquartered in North Berwick, Scotland, with a globally distributed team of country and sector coordinators across the UK, China, Japan, Bangladesh, India, Indonesia, Pakistan, Peru, the United States and Canada. Its core product is the ISEAL Code Compliant AWS Standard (Version 3.0 launched March 2026), which is independently certified through approved Conformity Assessment Bodies at Core, Gold and Platinum levels and explicitly engineered for interoperability with EU CSRD and ESRS E3 Water disclosure regimes.

AWS monetises primarily through organisational membership subscriptions (over 200 members spanning large multinational corporates, civil-society NGOs and public-sector bodies) supplemented by paid professional services — a multi-language Training Programme (Introduction to Water Stewardship, AWS Standard System Training, Internal Auditor Training, short courses in Chinese), a Professional Credentialing programme, and convening revenue around events such as the annual Global Water Stewardship Forum in Edinburgh. Distribution runs through direct enterprise engagement, third-party auditors, GTM partnerships with Inogen Alliance, Waterplan, IWA and WWF, and development-bank collaborations with the World Bank and GIZ on water-reuse programmes in Bangladesh and Tanzania.

Scale indicators6 records

Recent moves6 records

Expansion highlights6 records

Broad incumbents

• Trucost (S&P Global):
• CDP (formerly Carbon Disclosure Project): Global disclosure system for environmental impact including water security. Overlaps with AWS as both enterprises compete for ESG/regulatory mindshare on corporate water reporting and assurance, though CDP is a broader climate/forest/water platform.
• GRI (Global Reporting Initiative): Sets global sustainability reporting standards, including water-related disclosures (GRI 303). Competes in the corporate water disclosure/standards layer; AWS's V3.0 explicitly maps to GRI-aligned frameworks, indicating direct interoperability competition.

Direct peers

• UN Global Compact CEO Water Mandate: UN-backed initiative advancing corporate water stewardship. Direct peer in convening companies around water stewardship principles and disclosure; AWS competes for enterprise engagement on water strategy and reporting.
• Water Footprint Network: Develops the Water Footprint Assessment methodology and standards for measuring corporate/product water use. Direct peer offering a competing methodology-based framework that enterprises weigh against the AWS Standard for water stewardship.

Emerging players

• World Resources Institute (WRI) Aqueduct: Provides the Aqueduct Water Risk Atlas and corporate water risk tools. Comparable as an enabling data/assessment layer that feeds into water stewardship programs like AWS, though focused on risk mapping rather than site-level certification.
• Science Based Targets for Nature (SBTN): Develops science-based targets for nature including freshwater, positioning itself as an alternative methodology layer for corporate water action. Emerging peer in the standards/methodology space for water.
