How data was acquired	-Raw data on the environmental impact of all the food's life cycle stages were extracted from existing public databases and from recent publications. -Life cycle inventory data of Agri-footprint and Ecoinvent were accessed using the software program SimaPro (Multi-user version 8.4.0.0). -Raw data on the environmental impact of all the food's life cycle stages were compiled to calculate environmental impact of the food as consumed using Microsoft Excel.
Data format	Raw processed and analysed data, descriptive statistics The raw data are available on a data repository.
Experimental factors	Data taken from published sources were processed to provide estimates of GHGE and LU for assessing the environmental impact of an individual diet.
Experimental features	No experimental work was carried out; calculations were based on published data.
Data source location	Foods included in the SHARP-ID were based on the reported food intake of the four European countries included in the SUSFANS project, i.e. Denmark, Czech Republic, Italy and France, resulting in a list of 944 food items coded with a unique FoodEx2-code.
Data accessibility	Estimates of environmental impact for a food, as coded by the FoodEx2, are available on a data repository with the following doi https://doi.org/10.17026/dans-xvh-x9wz. The associated file that includes all the calculations is available upon request for scientific applications.
