Photochemical ozone formation

brightway-flows 1,392 factors over 672 flows, 1,390 of them non-zero

European Commission — JRC 1,386 factors over 666 flows, 1,384 of them non-zero

GreenDelta 493 factors over 169 flows, 493 of them non-zero

ecoinvent Centre 259 factors over 259 flows, 259 of them non-zero

Compare two of these implementations — only the rows where they state different numbers.

One row per flow and place. Published as is what this list did with the row: agreed where more than one implementation stated the same number, sole where only one spoke, and nothing at all where the disagreement went to a queue instead.
