Could a tax on animal-based foods improve diet sustainability?
The global food system is estimated to contribute 30% of total Greenhouse gas (GHG) emissions. In this context, the EU has committed to reducing GHG emissions by 40% relative to 1990 levels by 2030 and by 80% by 2050. Apart from the necessary policies of citizen information and production regulation, could a consumer tax on the most Greenhouse gas-emitting foods be a relevant tool to improve diet sustainability? Could it combine greener and healthier diets with a limited social cost?
