Salvidia runs on a simple loop: bring data in, review the categorisation, watch the results update. This page covers each step, plus the two mistakes that cause most bad numbers. Four input paths, an accounting platform, activity data, supplier figures and spreadsheet import, all feed one review step which produces results by scope and category, with a feedback loop back to activity data as you upgrade categories each year. The dotted line is the part that matters over time. Each year you move another category from estimated to measured, and the loop runs again.

​
Getting data in

Four ways to add data, and most assessments use several:

Connect your accounting platform

Reaches every category you spend money on at once. Salvidia reads the ledger for the period and categorises the transactions. Best for broad Scope 3 coverage.

Import from CSV

Export from any system: utility portals, travel platforms, waste contractors. Best for bulk activity data.

Enter data directly

For small volumes. A handful of fuel receipts, one site’s electricity, refrigerant top-ups. Quicker than building a spreadsheet.

Use supplier figures

Where a supplier publishes real emissions data for what they sold you, it replaces the industry average and improves that category directly.
Energy, travel, waste, and product data belong in the tables built for physical quantities. Purchased goods and services is the flexible one, and takes activity data or spend.

​
Reviewing categorisation

Every entry lands in a category such as electricity, flights, purchased services, or waste, and every category maps to a scope and an emission factor. Two habits keep it accurate:
  1. Review the biggest items first. Sort by value and check the top entries. A single large miscategorised invoice distorts your results more than a hundred small ones.
  2. Fix the category, not the number. If something is wrong, recategorise it. Never adjust results by editing quantities to compensate: it breaks the audit trail, which is the thing that makes your number defensible.

​
Avoiding double counting

The most common data-quality failure is the same emissions entering twice, once as spend and once as activity data. Electricity is the classic: you enter kWh from your bills, and the ledger still contains the payments to your retailer. Your Scope 2 is now roughly double what it should be. The rule: when you add activity data for a category, exclude the corresponding spend. Salvidia’s structured tables give each type of data a defined home, which makes this manageable. The check is still yours to make.

​
Handling gaps

Missing data is normal, especially in year one. The accepted approach:
  • Estimate transparently. If one site’s electricity bills are missing, extrapolate from a comparable site or period, and note that you did.
  • Do not leave material categories at zero. A rough estimate with a note beats a silent gap. A zero reads as “we have no emissions here,” which is a claim you probably cannot support.
  • Record your assumptions when you make them. Anything an auditor or a client might ask about later should be written down at the time, not reconstructed a year afterwards from memory.
That last habit is the one people skip and regret. The assumption is obvious while you are making it and invisible six months later.
