Interpretation
The contribution analysis indicates that raw materials supply (A1) is the most significant driver in every impact category with contributions ranging from 60 to 87%. Specifically, PVC resin is the top contributor across every impact category. This is not surprising as PVC resin makes up 74.3% of the composition of extruded PVC electrical conduits. After A1, the second driver is manufacturing (A3) for most impact categories, with the exception of EP, contributing 6% to 34%. Of the precursors included A3, grid electricity and natural gas are the main contributors, but the latter had minor impacts across all impact categories at ≤1%. Therefore, most of the impacts in A3 were due to the consumption of electricity. For EP, the second most important LCIA was the disposal of the PVC conduits at end-of-life (C4).
LCIA results are relative expressions and do not predict impacts on category endpoints, the exceeding of thresholds, safety margins or risks. EPDs are comparable only when they follow the same PCR, functional unit and system boundary. The full EPD (PDF) contains the methodology, scenario assumptions and verification statement.
