I don't see any point in (and am confused by) the OR (pe2se(enty,enty2,te) AND sameas(enty3,"cco2")) part. This would come into play for combinations of (pety,sety,te,"cco2") that are not present in emi2te yet have non-zero data in pm_emifac. This might happen if new data is included in ./core/input/generisdata_emi.put, but is not the case at the moment.
However, these entries would be excluded from the equation in any case, since it sums over emi2te, of which they are not a part. (Incidentally, this sum does nothing productive besides excluding the non-existent cases that were manually included.)
Do you have any idea what was the reasoning behind this? I will delete it, unless there's some foreseeable edge-case where this is necessary.

Bump @strefler.
