Dear all best regards.
I am developing a carbon footprint assessment comparing Simapro and OpenLCA and when I checked the impact factor in the IPCC 2013 method in Simapro, for example, there are substances such as Butane, perfluoro- with a GWP of 9200 kg CO2 eq / kg, but in the OpenLCA LCIA IPCC 2013 there is no such substance.
I would like to know that occurs and how could I solve that situation.
Thanks a lot in advance.
Regards
