Double counting happens when the same emission arrives through two routes. The usual cause is holding both an invoice and a general ledger line for the same purchase.
Avarni does not detect it for you. Check for it.
Where it happens
Both routes present | What to do |
Electricity invoices and a utilities account in the ledger | Exclude the utilities account |
Fuel card data and a motor vehicle account | Exclude the motor vehicle account |
Waste contractor reports and a waste account | Exclude the waste account |
Water invoices and a water account | Exclude the water account |
A separate upload, such as paper, and the account it sits in | Exclude that account |
The rule is simple. Where you have activity data for a source, exclude the spend for that same source.
Exclude at the right level
Exclude the specific account, not the whole category.
If you have meter data for three sites and no data for a fourth, exclude only the spend for the three. The fourth site keeps its spend-based figure. Use a classification rule with a condition on the site or account.
Scope 2 location-based and market-based
Record both. Both are Scope 2, and Avarni does not check one against the other.
Anything that does not split by GHG category adds them together. The Overview page does this. To see them separately, group or filter by GHG category.
When you report, disclose them as separate lines. Do not add them.
Rent and leases
If you pay rent for a site and report that site's electricity in Scope 2, the rent is not also Category 1.
Intercompany transactions
A charge between two entities in your group is counted once at the point of external purchase. Exclude intercompany accounts from your ledger.
How to check
After your first calculation, compare your largest categories against your activity data:
Filter the Emissions Hub to one GHG category.
Group by supplier.
Look for suppliers appearing both as invoice-based rows and as spend-based rows.
A supplier appearing twice is either double counted or split between sites. Check which.
