| Use advice for data set | Users of this data set should consider the technological applicability, including the specificity of regional practices and inputs. It is recommended to take into account the representativeness of the data for the intended agricultural context when applying this LCA data. Additionally, users should be mindful of the methodological framework and assumptions used in the quantification of GHG emissions. The exclusion or inclusion of carbon sequestration effects due to vegetable growth and organic fertilizer application should be handled in accordance with the goal and scope of the intended assessment. The system boundary for this data set is confined to the entire process of open-field vegetable production; thus, users should not apply it to different agricultural systems without proper adaptation. |
| Technical purpose of product or process | The data set represents the greenhouse gas emissions from the life cycle of vegetable production, specifically open-field cultivation of tomatoes, cucumbers, Chinese cabbage, and radishes in China. This data is pivotal for understanding the environmental impacts of agricultural practices and is applicable for researchers, policymakers, and agricultural businesses aiming for sustainable farming methodologies and the reduction of agricultural emissions. The data set can serve as a baseline for comparison among different regions within China and for the assessment of potential emission reduction strategies. |

| General comment on data set | The boundary of the system is concentrated in the whole process of open field vegetable production (from sowing to harvesting), which is divided into agricultural phase and agricultural phase. The agricultural phase focuses on greenhouse gas emissions from the production and transportation of fertilizers (fertilizers and organic fertilizers), pesticides and agricultural film. The agricultural stage mainly focuses on the greenhouse gas emissions generated by the application process of fertilizer and pesticide, the diesel consumption and artificial energy consumption in the process of agricultural operation (tillage, irrigation, etc.), and the fixation of soil organic carbon caused by the net primary productivity of vegetables and the input of organic fertilizer [16].

| Technology description including background system | Based on national agricultural statistical data, using the life cycle assessment (LCA) method, the net greenhouse gas emissions (NGHGE) of four typical field vegetable productions in China, including open-field tomatoes, cucumbers, Chinese cabbage, and radishes, were quantified. The study compared the differences in net greenhouse gas emissions among vegetable types and provinces, and analyzed emission reduction measures. |
