Water Neutrality

Water neutrality is achieved when an entity reduces its direct and indirect water footprint and, through verified projects, offsets the remaining volume to reach a net-zero or positive impact on water availability and quality. In practice it follows a hierarchy: first measure, then reduce as much as possible, and only then replenish or offset what cannot be avoided.

The concept is closely related to corporate goals such as being "water positive" (replenishing more water than is consumed) and to the United Nations Sustainable Development Goal 6 on clean water and sanitation. Because water is a local resource, neutrality is most meaningful when reductions and replenishment happen in the same water-stressed basins where the impact occurs.

Steps to achieve water neutrality

1. Full measurement according to ISO 14046, including the most material parts of the supply chain.
2. Internal reduction: efficiency, reuse and recycling to cut withdrawals and consumption.
3. Replenishment or offsetting in high-stress basins, weighted by scarcity using factors such as AWARE.
4. Verification and reporting through frameworks such as the Alliance for Water Stewardship (AWS) Standard and CDP Water Security.
5. Transparency: publish the methodology, assumptions and assurance.

Key metrics

• Replenishment ratio: cubic metres replenished divided by cubic metres consumed; a value of 1.0 or above indicates volumetric neutrality.
• Footprint coverage: the share of the water footprint included in the calculation, including supply-chain water.
• Consumptive versus withdrawn water: only consumptive use permanently removes water from a basin, so it is the focus of replenishment.

Examples of corporate commitments

Several large companies have adopted water-positive or replenishment goals. Microsoft committed in 2020 to be water positive by 2030 and reports investing in dozens of replenishment projects worldwide. The Coca-Cola Company announced a 2030 water security strategy built around reducing, reusing and locally replenishing the water used in its operations. These programmes rely on volumetric water benefit accounting and independent verification, and the specific figures should always be taken from each company's own published reporting.

Why it matters

Water neutrality is a resilience strategy that reduces exposure to droughts, restrictions and reputational risk in water-stressed regions, and it aligns operations with SDGs 6 and 12. To be credible it must rest on robust measurement, genuine reduction and locally relevant, verified replenishment, not on offsets alone.
