Development of the Food Systems–Related Greenhouse Gas Emissions Factor Database Using the Korea National Health and Nutrition Examination Survey (2016–2018)

This study highlights the utility of a full-system GHGE database that addresses prior limitations in global estimates. Korean dietary patterns exceed climate-compatible thresholds, with substantial variation by demographic groups. These findings support the need for equity-focused strategies and integration of environmental considerations into national dietary guidelines for sustainable and climate-resilient food systems. https://doi.org/10.1289/EHP15534.
