| Use advice for data set | 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. |
| Technical purpose of product or process | This dataset represents the production of Polyvinyl Chloride (PVC) by using the Ethylene Method in China. PVC produced through this method is commonly employed in a variety of applications including construction materials such as pipes and fittings, in the manufacturing of cables and wiring, consumer goods, and medical devices. The dataset evaluates the environmental impact of the PVC produced from both ethylene and calcium carbide processes. |

| Time representativeness | |
| Time representativeness description | Process-based data from China were used, yet if not available, data from Europe were applied instead. The electricity input was developed based on the national grid structure in China (Table S3), which was obtained from the share of the electric power structure in 2020 (National Bureau Statistics of China, 2020). |
