| 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 | When applying this LCA data, users must consider the specific regional context (e.g., Sichuan, China) as environmental impacts may vary by location. This data set relies on a simplified version of the life cycle impact assessment which uses specific indicators. It is advised to update emission factors and methodological approaches to ensure relevance and accuracy. Additionally, users should note the consumption of fodder, electricity, and diesel in the production phase and apply appropriate CO2 emission coefficients and electricity emission factors sourced from Hospido et al. (2003) and the NDRC (2014). Pay attention to the specific treatment of end-of-life waste (e.g., milk packaging) as it is transported to a landfill for disposal. |
| Technical purpose of product or process | The data set describes the full life cycle of a local branded pure milk production, which includes raw milk production at dairy farms and subsequent processing. The milk produced is intended for consumer consumption as a nutritional and food product. This Life Cycle Assessment (LCA) data set would be particularly useful for the dairy industry, food product manufacturers, and environmental analysts looking to quantify the environmental impacts of milk production, from dairy farming to distribution. |

| 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. |
