"Improved food intake in OECD countries as a key global climate mitigation driver"
by Cunha, Bruno, Rafael Garaffa and Angelo Gurgel

Global food systems are struggling to deliver nutritious diets in an equitable manner. Growing population, accelerating migration to cities, transitions in dietary habits to more processed and animal-source based foods, and land-use and environmental change are putting the food system under ever-increasing pressure. A food transformation from food systems that operate within planetary boundaries towards healthy, culturally appropriate and available diets for all is one of the greatest health and environmental challenges of the 21st century. This puts the onus on food, requiring an urgent shift in mindset to recognize the importance of consumers’ choices and of the production of the agricultural sector to meet targets for the coming decade set in the United Nations Sustainable Development Goals (SDGs) and in the Paris Climate Agreement. As such, the concept of “healthy diets” gained importance in the debate, especially in relation to the trade-offs between plant- and animal-based foods. To address these issues, we use a computable general equilibrium model (CGE) to explore how a voluntary improved food intake in OECD countries contributes to global greenhouse gas (GHG) emissions reduction. The mitigating role of behavioral changes and the effects of ambitious market-based climate policy are assessed by comparing future scenarios. A climate-related cost of the global food system provides crucial information for effective governance and policy design. We highlight the opportunity cost of the refusal to an improved food intake in OECD countries.
