Hi

In the LCIA Method 2.1.3 – updated Blog Post, you stated that the "IPCC 2021 GWP 100 (according to UNFCCC/Kyoto Protocol)" method only contains the compounds laid out by the linked report [carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), hydrofluorocarbons (HFCs), perfluorocarbons (PCFs), sulphur hexafluoride (SF6) and nitrogen trifluoride (NF3)].

However, I noticed that the 1,2,3,4-Tetrachlorocyclobutane flow (UUID: b3ccc4b8-4d46-4b03-8fcf-1a877991eb7c) is present too, and to my understanding, it does not belong to only of these 7 types. 

Am I misunderstanding the categorisation? and if so, which category does to belong to?

Or is this flow there erroneously? 

thank you for clarifying, and regards, 

Matthias
