Notes ¶ Freshwater eutrophication is primarily driven by orthophosphate emissions associated with wind and solar power plant construction. Because the residual mix contains fewer renewable resources, it includes less wind and solar construction activity, resulting in lower freshwater eutrophication impacts.
