Sustainability is supposed to be strategy. Right now it's a scramble, and it starts in your supply chain.
A retail partner demands the Scope 3 footprint for one SKU. Comply by Friday or get delisted. So the questionnaire goes out - again - to suppliers who have never been asked for emissions data, while someone chases a tier-2 vendor who doesn't answer and the gaps get filled with generic industry averages.
That's the Compliance-to-Reality Gap. It isn't a reporting failure. It's a sourcing failure with a reporting deadline attached.
Here's the math nobody likes. The majority of your footprint sits with suppliers you don't control, at tiers you can't see. Your clean data covers Scope 1 and 2: your plants, your energy, your fleet. Everything that actually moves the number lives in someone else's ERP.
So planning happens twice. Sourcing picks the vendor on cost, lead time, and OTIF. Six months later, sustainability finds out what that decision did to the carbon number and gets asked to defend it. Carbon shows up as an output to explain, never as an input to the decision.
Then the auditor arrives. They look at the spreadsheet where you blended real supplier data with proxy factors, and they call it what it is: unsupported. Now it isn't a carbon problem. It's a greenwashing exposure.
Which is why the reflex is always another questionnaire, another scorecard, another 400 vendors on a distribution list. It never works, for a reason that has nothing to do with the questions. You're asking suppliers to hand-calculate a number they don't track, for a deadline that isn't theirs, with no consequence for guessing. Response rates are low, quality is worse, and you end up back in Shadow Excel praying the formulas hold.
What actually holds up is simpler. Put carbon in the same system as cost, at the same granularity as your BOM. An audit-proof trail for Scope 1 and 2. Defensible, methodology-backed estimation where deep-tier data is thin - the kind that survives scrutiny because you can show your work, not because you found better averages.
That's the difference between a report and evidence.
We don't bring a one-size-fits-all model. We build the engine around your BOM, your supplier tiers, and your actual regulatory exposure, so carbon becomes a variable your planners can act on before the PO goes out, not after the SKU ships.
If your next Scope 3 request would send your team back into the spreadsheet, put thirty minutes on my calendar. Bring one SKU and one supplier tier you can't see into, and we'll work out what a defensible number would actually take.
