Life-cycle assessments (LCA) were conducted for 80 different pizzas representative of the French retail market to study the possible differences in environmental impact between various items belonging to the same food product category. The LCAs were conducted using the "EF 3.0 Method (adapted) V1.00 / EF 3.0 normalization and weighting set" on SimaPro software. Most of the data used were taken from the AGRIBALYSE 3.0 and EcoInvent 3.6 databases. The dataset contains details on products, life-cycle inventories (LCI) and LCIA results.
