Two commercially available synthesis methods (calcium carbide, ethylene) were assessed for PVC production in China. When using this dataset, ensure that the scope of the analysis aligns with the production process covered—specifically, the Ethylene Method in China. If modeling PVC production processes, consider that the data may incorporate information from European sources where Chinese data are lacking. Pay special attention to the electricity input, which is based on the national grid structure of China, reflecting the electric power structure data of 2020. For consistent environmental impact assessment, the ReCiPe method (Europe H/H) was used. It's important to maintain the defined functional unit of 1 kg resin production when extrapolating results so that different datasets can be reliably compared.
