Food consumption is a major driver of environmental impacts. This paper designs carbon taxation scenarios on food, including or not subsidies, and assess their distributional, environmental and nutritional effects. Food price elasticities are estimated from an EASI demand system, and distributional effects are estimated on continuous distribution, which enables us to compute an inequality index. Our results show that a tax policy may be effective in reducing emissions and that a revenue-neutral scenario including subsidies improves as well nutritional and equity aspects. However, to obtain a more important emissions mitigation (-15%), taxing all foods may be considered, with no adverse nutritional and equity effects.
