Harmonised dataset for decomposing and matching food items in dietary data for high-resolution modelling

The dataset includes a decomposition table as well as matching tables linking FoodEx2 items to food item labels of three commonly used environmental impact databases (Poore and Nemecek dataset, Agribalyse v3.2, Ecoinvent v3.10). Yield conversion factors and consumer food waste coefficients are incorporated to support full food supply chain impact modelling. The dataset is complemented by an R script that supports semi-automatic matching, which can easily be applied to other datasets. 

This dataset incorporates term codes and term names derived from the EFSA FoodEx2 classification system. EFSA-derived material is © European Food Safety Authority and is re-used with EFSA acknowledged as the source. 

For part of the ingredient-level decompositions, input data from Annex A to the technical report on the Raw Primary Commodity (RPC) model (published under CC BY 4.0) were used.
