How do I handle scope-3 numbers I can't fully trust?

You can count your own smokestack. You can weigh what leaves your loading dock. But your supplier's supplier's supplier is a fog, and no amount of software will burn it off completely. That is not an excuse to stop trying. It is simply the truth of the task, and you waste effort pretending otherwise. Someone above you wants a clean number — for a report, a campaign, a comparison against a rival. They want the certainty you do not have. This pressure will not stop because you explain the fog to them once. It will return, dressed differently, every quarter. So stop trying to solve scope 3 perfectly. That is not the actual task in front of you. The actual task is smaller and entirely yours: decide, today, what you will sign your name to, and what you will refuse to round up.

Mostly you & the coach

A little with peers

The person already understands measurement mechanics; what trips them up is judgment under pressure, so the page leans slightly toward coaching while still teaching how to handle categories and disclosure.

What’s really going on

You will never measure scope 3 with full certainty. Neither will anyone else. That is not your failure — it is the nature of the thing. What is within your power: choose honest ranges over false precision, disclose your method plainly, and refuse to let marketing turn your uncertainty into a promise it cannot keep.

🔒 What you’ll build togetherUnlock by starting

A moveWrite one line for each scope-3 category: 'measured,' 'estimated,' or 'unknown.' Do this before your next report, not during it.

A moveWhen someone demands a single number, give the range and say the assumption behind it out loud, in the same sentence.

A moveWrite down the exact sentence you will say when asked to round up your certainty. Practice it before you need it, not in the moment.

A movePick one scope-3 category to improve with real data this quarter. Leave the other fourteen alone until their turn comes.

A moveIf you are asked to falsify or hide a number outright, that is no longer a measurement problem. Take it to someone outside the pressure — a mentor, an ethics line, legal counsel.

What changes unlock by starting

You can defend every number you publish, in plain terms, to anyone who asks.
You stop calling a rough estimate a precise fact.
You have a rehearsed answer ready the next time someone asks you to inflate or hide a number.
Your data improves category by category, instead of stalling under the weight of trying to perfect all of it at once.

One object, two jobs: a public answer to a real problem, and — the moment you start the chat — Aurelius’s live plan for your version of it.
