I also have not seen any analog translations for other categories than GWP, but I like using the Gulf of Mexico Dead Zone for explaining what eutrophication is. LCA’s normalization and weighing factors are supposed to help with understanding the scope of impacts across categories but there are issues with subjectivity and regional priorities. For example, eutrophication has regional effects (unlike GWP which has global effects). I like the idea of expressing impacts as as a ratio of annual impacts of an average person, like Rob mentioned. Another option would be to compare to the eutrophication impacts of growing different kinds of food - I believe most eutrophication impacts come from the agricultural sector. Lastly, as far as I know, the modeling of eutrophication related emissions in some background datasets is not very robust, resulting in large uncertainties. That covers eutrophication, now onto other categories…
