What is the GWP of R-134a?
R-134a has a Global Warming Potential of 1,530 (100-year, IPCC AR6), meaning 1 kg of R-134a has the same warming effect as 1,530 kg of CO₂.
The factor is the easy part
Looking up a factor takes seconds. Getting the quantity off a concrete docket, a subcontractor invoice or a freight consignment, and proving later where it came from, is where Scope 3 reporting for AASB S2 breaks. Carbonly reads physical quantities off supplier documents, matches each line to an NGA or construction EPD factor, and keeps every number traced to its source document. Why Scope 3 breaks.
