What are the most common mistakes when using the factors?

Question

Accepted Answer

Summing FLAG (excl. LUC) into the total. It's a subset of the total; report it separately. Using now-cast years for reporting. Use inflation-corrected observed years instead. Comparing a Scope 1 figure from one source with a cradle-to-gate total from another. For most products they differ by an order of magnitude, and neither is wrong (see should you always sum the scopes?). Reading across from the Standard sheet to the Market Avg. sheet by accident. They answer different questions and can differ substantially. Adding a scarcity-weighted water figure to an unweighted one, or comparing the two. They are different quantities; check the unit on the column to see which you have.
