Most common units for environmental impacts

Why not express "Emissions of gases that contribute to the creation of ground level ozone" in "kg ethene-equivalents" as the GPI recomends and the most used LCA methodologies express, instead of the not so common "kg NMVOC-equivalents" that you propose in the PCR draft?

And I would like to suggest to express "Emission of substances contributing to eutrophication" in "kg PO4-Eq" (as commonly expressed), instead of distinguishing between freshwater and marine (with different units, kg P-equivalents / kg N-equivalents).

Harmonization between diferent PCR should be taken into account.

Some things should be obvious: - As the most common calculation methods do, eutrophication must be expressed in PO4 3- eq - As the most common calculation methods do, ground level ozone should be expressed in C2H4 eq - As we all know, we should write Kilowatt (KW) instead of kilowatt (MW) - And finally, Energy has never been expressed in Kilowatt per hour but it is Kilowatt time hour (KW.h)........
