Climate mitigation policies increasingly extend beyond production and energy systems to encompass everyday consumption practices, including food consumption and waste management. This study examines income- and household-type differences in food-related carbon emissions behaviors among South Korean households, focusing on beef and grain consumption and food waste generation. Using nationally representative household survey data, we analyze how emissions-related behaviors vary across income groups and household structures at both the consumption and disposal stages. Results show clear heterogeneity: higher-income households exhibit greater consumption of carbon-intensive foods, particularly beef, and higher overall food-related carbon emissions, whereas lower-income households display comparatively lower emissions. Differences across household structures further indicate variation in food waste generation and per-capita emissions. These patterns are consistent with existing evidence on consumption-based carbon inequality and reflect differences in affordability, household composition, and constrained choice. The findings document systematic variation in consumption and waste patterns across income groups and household structures.
