TLDR: Sustainability programmes stall about six months in, when ownership and data still live in one person’s head. The fix is structural: an operating model that outlives any single champion.
The month-six wall
A launch carries energy for a quarter or two. Then the first full reporting cycle arrives, the data takes longer than anyone planned, and the programme slows to a crawl. The pattern is common because the underlying problem is shared: environmental, social, and governance (ESG) work depends on data that most companies still collect by hand. Data quality is the top ESG data challenge executives name — 57% call it the biggest and 88% place it in their top three, and the documentation, review, and approval steps consume the rest of the calendar. KPMG finds that businesses hit significant hurdles simply gathering the numbers. Enthusiasm fades while the spreadsheets multiply.
The deeper reason: ownership lives in a person
Most companies build structural accountability for finance and compliance, with named owners, defined controls, and a cadence that survives turnover. ESG accountability often lives in the commitment of one leader or team, and it travels with them when they move on. A programme anchored to a person inherits that person’s calendar, and it stalls the moment their attention shifts to the next priority.
That is the month-six wall in one sentence: the launch energy was personal, and personal energy is finite.
The setup that carries it through
Durable programmes share a shape. Ownership is structural: a named accountable executive, a responsible, accountable, consulted, informed (RACI) map, and controls that sit in the same governance as financial reporting. The data pipeline is industrialised: companies replace manual collection with a dedicated platform such as Persefoni or Workiva, so every figure carries a source and an audit trail, the standard Mezyan sets out in its guide to verifiable carbon data. And the cadence is fixed: a monthly close for ESG data mirrors the monthly close for finance, which keeps the work continuous and small, a steady rhythm that retires the annual scramble.
Each element does the same job: it moves the programme out of one person’s head and into the organisation’s operating system.
Exhibit 1 — Person-dependent programmes stall; structural ones endure
| Element | Person-dependent (stalls at month six) | Structural (carries through) |
|---|---|---|
| Ownership | Rests on one leader’s commitment; leaves when they do | Named accountable executive and RACI map, inside the same governance as finance |
| Data pipeline | Manual collection in spreadsheets, no audit trail | Industrialised platform; every figure carries a source and audit trail |
| Cadence | Annual scramble powered by personal energy | Fixed monthly close mirroring the finance close |

The first 90 days
The remedy depends on where a company stands. A new programme should name its accountable executive and draw its RACI before it captures a single metric, so ownership is structural from day one. A stalling programme should run a short diagnostic: locate the source behind every number, the single points of failure, and the manual steps, then industrialise the worst three first. Leadership should place ESG data inside the same governance cadence as financial data, which converts a campaign into an operating function.
A programme already feeling the month-six drag can work with Mezyan to industrialise its ESG data pipeline before the next reporting cycle.
FAQ
Why do ESG programmes lose momentum after launch?
The first full reporting cycle reveals how much data sits in spreadsheets and manual steps, and the effort outgrows the original team. Structural ownership and an industrialised data pipeline keep the momentum going.
What is structural accountability for ESG?
Named owners, defined controls, and a governance cadence that sits alongside financial reporting, so the programme keeps running when individuals move on.
How often should ESG data be collected?
A monthly close, mirroring finance, keeps the work small and continuous and produces audit-ready numbers throughout the year.
