Field note / Global supply chain / Water
Notes from a global supply chain perspective, on why water programs stall at the factory gate — and how to build a taskforce that outlives its own KPI.
01 The root cause
I have watched a lot of water programs go quiet. Not fail loudly — just thin out. The dashboard stays green, the certificate renews, the supplier fills the template on time, and the river outside the fence keeps dropping.
So I stopped asking whether it was a KPI problem, a project problem, or a verification problem. It is none of them, and it is all of them, because all three share the same hidden assumption: that water is a quantity a single site can own. It isn't. Water is a shared, moving, seasonal, political system. A factory can only ever hold a share of it.
Certification and verification are not the enemy. They are grammar — useful, necessary, and completely silent on whether anything got better in the catchment. A verified number in an over-allocated basin is a well-documented loss.
Everyone feels safe once there is a KPI. The water does not. The line I keep coming back to
We manage per site. Water behaves per basin. Cutting 20% inside a fence in a basin where agriculture takes most of the withdrawal is real work with almost no hydrological signal.
We fund twelve months. Aquifers, watersheds and utilities answer in decades. A program designed to be "completed" is a program designed to stop.
We collect evidence of compliance, not evidence of change. Nobody was ever asked whether the neighbours' wells still work in April.
02 The real water question
Most programs quietly collapse all four into the first one, because the first one is the only one with a meter on it.
Intake, reuse, effluent quality, chemistry, boilers, dyehouses. The part we can meter and therefore the part we over-report. Real, worth doing, low-cost more often than we admit — and never the whole story.
Metered · Fast · Ours to fixThe tap outside the fence. Drinking water and sanitation for workers, their families, the settlement the factory pulled into being. Billions still live without safely managed drinking water — many of them make our products.
Human · Shared · Rarely countedThe basin, the aquifer, the recharge, the upstream farm. For most consumer goods the overwhelming share of the water footprint sits in tier 3–4 and in agriculture, which takes roughly 70% of global freshwater withdrawals.
Upstream · Invisible · DecisiveDrought, flood, allocation, price, permits, social licence. Climate arrives as water, almost every time. This is the water that stops a line, not the water on a scorecard.

countries — home to roughly a quarter of the world's population — face extremely high water stress every year, using over 80% of their renewable supply.

04 Definitions first
Every water taskforce I have seen struggle was really struggling over undefined language. Six definitions, written down, signed off by procurement and by the suppliers, save a year.
05 Designing it with no budget
Relationship, workflow, convening power and influence are a supply chain's real capital. Spend those. Three horizons, running in parallel, never sequential.
06 How others have done it
Five approaches worth studying — each set its target, plan, progress and claim differently. Note how few of them are a single-company KPI.
A CEO-led coalition organising members around collective action in shared priority basins rather than around each company's own footprint — the target is stated as positive water impact in stressed basins by 2030.
Target: basin-level, collective · Plan: members co-invest in the same catchments · Claim: contribution with named partners
Water Resilience CoalitionInstead of every brand auditing the same mill against a different wastewater expectation, the industry adopted one wastewater guideline and one reporting platform. The unlock was not a stricter limit — it was removing duplication so suppliers could actually act.
Target: shared discharge parameters · Plan: one platform, many brands · Claim: conformance levels, published
ZDHC Roadmap to ZeroGrew out of mill-efficiency work that showed most water and energy savings in wet processing come from low- and no-cost operational fixes. Verified savings, an open playbook, and financing routes — designed so improvements spread beyond one brand's suppliers.
Target: verified savings per facility · Plan: diagnose, implement, verify, publish · Claim: aggregated, measured savings
Apparel Impact InstituteA site-level standard that only works if the site engages its catchment: understand the shared challenge, act with others, disclose. Useful as a grammar for supplier teams — dangerous only if treated as a trophy on a wall.
Target: stewardship outcomes at site + catchment · Plan: gather, commit, implement, evaluate · Claim: certified, with catchment context
Alliance for Water StewardshipFreshwater targets set from the state of the basin — quantity and quality — rather than from an arbitrary percentage cut. Early corporate cohorts have gone through validation, which is exactly where the method's friction becomes visible and fixable.
Target: basin-derived thresholds · Plan: assess, prioritise, measure, act, track · Claim: validated, basin-specific
Science Based Targets NetworkA multi-stakeholder initiative mobilising business on water, sanitation and hygiene — in the workplace, in the supply chain, and in the communities where workers live. The cheapest, most human entry point into "water in the community".
Target: access floors for workers · Plan: pledge, assess, close gaps · Claim: people reached, not litres
WASH4Work07 Saying it honestly
The pressure to over-claim is where good water programs lose their credibility — usually in the last two weeks before a report goes to print.
"Across 46 facilities in three stressed basins, we implemented X and measured a Y% reduction in intake, verified by Z." Activity and measured result, nothing more.
"With the utility, two other buyers and a local NGO, we contributed to a project that restored dry-season supply to N households." Contribution, named partners, named basin.
"Basin condition improved on these indicators over this period, and our contribution was part of it." Requires monitoring you probably don't own yet. Build toward it.
Net-positive arithmetic that offsets a withdrawal in one stressed basin against a project in another. Water is not fungible across geographies. It never was.
08 Why this is worth the difficulty
Thousands of factories, in hundreds of basins, connected by relationships we spent twenty years building. That is not a reporting burden. That is infrastructure — for practice, for trust, for speed.
Designed as a KPI, it produces a number and a shrug. Designed as a living system — open definitions, shared standards, working alignment, good practice found and passed along, impact summarised honestly and moved forward — it starts to compound. And what emerges is bigger than water.
