You don’t need everything on this list to get started — an assessment built on spend data alone is a legitimate first pass. But the more of your major categories you can cover with real activity data, the more accurate your footprint becomes.

The one thing that unlocks the most

Your accounting ledger. Connecting your accounting platform (or exporting your general ledger for the reporting period) gives Salvidia visibility over everything you spent money on. That’s the backbone of Scope 3 coverage — purchases, services, freight, subscriptions, contractors — without weeks of manual data collection. Who has it: finance, in about five minutes.

Scope 1 — what you burn and leak

Scope 2 — the energy you buy

Bills beat estimates. If you can only chase down one piece of activity data, make it your electricity kWh — it’s usually easy to get and often a material slice of the footprint.

Scope 3 — everything your activity causes

Much of Scope 3 is covered automatically by your ledger via spend-based factors. The categories worth upgrading with activity data, because they’re usually material:

A realistic collection plan

  1. Week 1: connect the ledger. You now have a complete spend-based draft.
  2. Week 2: collect electricity, gas, and fuel — this locks down Scope 1 and 2 with real numbers.
  3. Week 3: chase the two or three biggest Scope 3 categories your draft reveals. Don’t guess which ones matter; let the first pass tell you.
That sequencing means you’re never blocked waiting for perfect data, and every week of effort goes to the categories that actually move your number.
