The same spreadsheet, third buyer this year

You already answered Buyer One in March. Buyer Two in June. Now Buyer Three wants “primary emissions data” in their template by Friday.

Look at the columns. Mass. Origin. Period. Intensity. Evidence flag. Different colours. Same substance.

That is the mid-tier pattern under Australia’s climate disclosure push: in-scope buyers need value-chain numbers for their Scope 3 packs. You feel it as spreadsheet weather. Not as a new science problem.

What is actually repeating

Each ask usually wants three things you already have somewhere:

1. Identity — which product / lot / period the number covers
2. Quantity linkage — how that intensity attaches to what you sold them
3. Intensity — a greenhouse gas figure from an engine, consultant, or prior pack you trust

What changes is the wrapper: portal login, column names, “please use our emission factors,” a new evidence checklist. Rebuilding the wrapper every time burns people who already did the hard part once.

What not to do

• Do not restart a farm model because a new buyer logo arrived.
• Do not treat every template as a legal filing. Most of these asks are commercial programme requests driven by the buyer’s disclosure calendar — not a Corporations Act duty on you.
• Do not invent a sharper number under time pressure. A consistent, sourced intensity you can explain beats a one-off that you cannot.

What to do instead

Keep one report-once pack: the identity, quantity linkage, and intensity you will reuse. When Buyer Three asks, grant them a view of that pack (anonymised, named, or named with evidence — whatever the commercial deal allows). Revoke when the relationship ends.

That is consent and allocation. It is not another calculator. The science product already ran; the join is who gets to see the output.

Bottom line

The third spreadsheet is rarely a new question. It is the same question wearing a new shirt. Answer once. Grant many. Stop paying the rebuild tax.
