Phase 2: Agricultural Life Cycle Inventory Dataset (Inputs, Outputs, and Data Sources)

Life cycle inventory (LCI) data constitute Phase 2 of life cycle assessment (LCA) and serve as the basis for calculating environmental impacts. In agricultural LCA studies, LCI data are often reported using different scopes, stages, units, and calculation methods, making it difficult to reproduce results and compare studies. The objective of this study is to compile and standardize Phase 2 LCI data reported in agricultural LCA studies into a structured dataset. The dataset is based on 184 peer-reviewed agricultural LCA studies published between 1999 and 2025. Data were collected through a systematic review using Google Scholar, and studies were included if they applied LCA to crop production systems and reported inventory data such as inputs, outputs, emission factors, or calculation equations. Inventory data were manually extracted from each study, including inputs and outputs, emission factors, equations, and data sources. The dataset is provided as an Excel workbook containing linked sheets for study identifiers, inputs, outputs, emission factors, equations, and data sources. Rather than providing newly harmonized inventory values, the dataset organizes extracted and categorized information reported in the reviewed studies using standardized identifiers and categories. The dataset includes more than 2000 inputs, around 1000 outputs, about 200 emission factors, and over 600 data sources. It is intended for researchers, practitioners, and tool developers to support LCI development, cross-study comparison, and integration into databases, knowledge bases, and decision-support tools.
