dataFIELD (database of Food Impacts on the Environment for Linking to Diets) was developed as part of the Wellcome Trust funded research project, "Linking Health and Environmental Outcomes to Dietary Behaviors in the United States", by CSS and researchers at Tulane University School of Public Health and Tropical Medicine. It aggregates data on the greenhouse gas emissions (GHGE) and cumulative energy demand (CED) associated with production of specific foods to facilitate linages with self-selected individual diets in the US National Health and Examination Survey (NHANES). This data represents generic “average” impact factors for the production of food commodities which, while not specific to the US, we feel is an appropriate representation of the production of food consumed in the US.

dataFIELD version 1.0 is now available for public use:


Additional documentation to familiarize users with the database structure and function is available here:


Development of the database and results on the GHGE and CED associated with individual self-selected US diets are reported in Heller et al 2018 Environ. Res. Lett. 13 044004. Please email Martin Heller at with comments or questions.
