Greenhouse gas (GHG) emissions associated with food consumption have become particularly pertinent issues given recent warnings that the planet recently has experienced its hottest year. One way proposed to reduce those emissions is through a carbon consumption taxes. This study uses consumption, nutrient and GHG emission data to estimate the impact of two ad-valorem taxes: one applied by food category and another by the carbon emission of the products. The results suggest that the carbon consumption tax scenarios would reduce GHG emissions by a greater quantity relative to the ad-valorem tax scenario; however, the intake of important nutrients will also decrease in these scenarios. Therefore, creating an environmentally sustainable and nutritious diet through taxation is challenging and requires compromise between the nutrition and environmental sustainability.
