Summary
This modelling study used a coupled economic and epidemiological framework to calculate health-internalising tax levels for red and processed meat across 149 world regions. The authors estimated that optimal taxation would increase processed meat prices by 25% on average (1–100% by income level) and red meat prices by 4%, reducing processed meat consumption by 16% globally whilst preventing approximately 222,000 deaths annually and reducing health costs by USD 41 billion. The work suggests market-based taxation aligned with health impacts could represent a feasible policy lever to reduce non-communicable disease burden whilst generating potential climate co-benefits.
UK applicability
As a high-income country, the United Kingdom would face higher optimal tax rates on processed meat (>100% based on the regional gradients reported) than lower-income nations. The findings are directly applicable to UK policy design on meat taxation, though implementation would depend on political will and consumer acceptance, and the model's assumptions about price elasticity and substitution patterns may require UK-specific validation.
Key measures
Optimal tax levels by region; percentage price increases for processed and red meat; changes in consumption; annual deaths prevented; health cost savings; global health burden costs in USD
Outcomes reported
The study modelled economically optimal tax levels for red and processed meat across 149 world regions and estimated the impacts on consumption patterns, health costs, and non-communicable disease mortality. It quantified the global health-related costs attributable to red and processed meat consumption and projected the effects of taxation on disease burden and healthcare expenditure.
