Well, you can aggregate any number of activities (and thus also
steps in an impact pathway) and thus obtain the desired
characterisation factors (for non-LCA people: A characterisation
factor is an output flow from a characterisation activity given in
relation to the input of the determining flow to be
characterised). And as such you can also store such aggregated
activity data obtained as "raw" data, e.g. for comparison to the
aggregated result of a specific more detailed modelling.
It stems from the fact that you asked about two different things: 1) carbon dioxide equivalents, which is a generic concept, 2) Global Warming Potentials, which are specific weighting factors for GreenHouseGases under a specific normative paradigm. Best regards Bo
