| Use advice for data set | Users utilizing this PP production data set need to consider the methodological constraints of the data sourced primarily from China, supplemented by European process data when Chinese data is unavailable. It is critical to apply this dataset correctly respecting the national grid structure of China for electricity input calculations. The ReCiPe method (Europe H/H) should be used for environmental impact assessment to ensure consistency with the given functional unit of 1 kg resin production. Special attention should be paid to the electricity mix and technology applicability when transposing these data to other regions or when evaluating scenarios with different grid compositions. |
| Technical purpose of product or process | Polypropylene (PP) production is an industrial process where ethylene and propylene, derived from early-stage crude oil refining, are polymerized to form PE and PP respectively. Polypropylene is commonly utilized in various applications such as packaging, textiles, automotive parts, and consumer goods due to its versatility, durability, and recyclability. |

| 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). |
