| Geographical representativeness description | The milk source base is located at Hongya Country, Southwestern Sichuan Province, China, about 147 kilometres far from Chengdu City, the provincial capital. The diary processing plant is located at Pixian, suburb of Chengdu City, which is about 175 kilometres far from the milk source base. The branded milk is mainly distributed to the central Chengdu City, about 40 kilometres distances from the diary processing plant. The milk packaging waste is transported to the municipal landfill for final disposal, about 30 kilometres away from the central city. |

| Use advice for data set | Users should consider only the direct contributions to pure milk production when utilizing this LCA data, focusing specifically on energy and material inputs, as well as carbon emissions during the life cycle stages of raw milk production, dairy processing, product transportation, and packaging waste disposal. The carbon footprint data must be calculated carefully using transportation loads and emissions factors as per IPCC guidelines to ensure accuracy in the impact assessment. It is also advised to contextualize the emissions data within the specific geographic parameters of the Sichuan province area detailed in the description. |
| Technical purpose of product or process | The local branded pure milk undergoes a production and distribution process essential for dairy consumption. The light-weight gasoline trucks are utilized for transporting raw milk from pasture to processing plants and further to distribution centers, catering to the need for fresh dairy delivery. Heavy-weight diesel trucks are used for transporting packaging waste to landfills, indicating an application in waste management and recycling logistics. |

| General comment on data set | According to the field investigation, light-weight gasoline truck in 2 tonnes of loading capacity is employed to transport the raw milk from the pasture to the processing plant, then to the distribution centre, and their distances are 175 kilometres and 40 kilometres, respectively. Heavy-weight disel truck in 10 tonnes of loading capacity is employed to transport the packaging waste to the municipal landfill, with a distance of 30 kilometres |

| Functional Unit | The Tetra Pak 1litre pure liquid milk is selected to assess its lifecycle based carbon footprint. |
| Technological representativeness | |
| Technology description including background system | This study only focused on processes that directly contributed to pure milk production, that is, only the effects of energy and material input and carbon emissions, as shown in Figure 1. The system boundary of milk life cycle is thus simplified and divided into four stages, namely, raw milk production, dairy product processing, product transportation and packaging waste disposal. |
