Hi, I think you mean characterisation factors - this is common for almost all LCA databases, only elementary flows have characterisation factors since only these go to nature or come from nature. There are only a few exceptions, for example the "proxy inventory" indicators in EPDs (exported energy, secondary material, hazardous waste, etc.).
