Summary
This systems modelling study quantifies the global and regional air quality benefits of dietary transitions towards more plant-based flexitarian, vegetarian, and vegan diets. By reducing emissions from food production—particularly animal agriculture—such dietary shifts could prevent 108,000–236,000 premature deaths globally (3–6%) and generate USD 0.6–1.3 trillion in economic gains. The analysis suggests dietary change represents a viable mitigation strategy for ambient air pollution in regions with intensive agriculture and high population density.
UK applicability
The study includes European data (9–21% mortality reduction potential) but does not report UK-specific findings; however, given the United Kingdom's intensive livestock sector and high population density in agricultural regions, similar proportional benefits to air quality and health might be anticipated, with potential policy relevance for food and environmental health initiatives.
Key measures
Premature mortality reductions (number and percentage by region); economic output gains (USD trillion); air pollution from methane and ammonia emissions; particulate matter and ground-level ozone formation
Outcomes reported
The study estimated premature mortality reductions and economic gains resulting from dietary shifts towards plant-based diets across multiple regions, using systems modelling to quantify changes in air pollution from reduced food production emissions.
