Summary
This Australian policy modelling study integrated greenhouse gas emissions pricing into food commodity prices and assessed downstream health, environmental and fiscal consequences. Using a coupled framework linking economic, environmental and health data, the authors found that a carbon price of AUD $23 per tonne CO2-equivalent could avoid 49,500 DALYs whilst reducing food-related emissions by 6% and generating AUD $866 million in public revenue. The work demonstrates that climate pricing policies on food can align with public health objectives to reduce diet-related disease burden.
UK applicability
The findings are potentially relevant to UK policy-making on carbon pricing and food systems, though the analysis is country-specific to Australian food consumption patterns, supply chains and disease burden. A similar modelling approach could be adapted to UK conditions to evaluate health-climate trade-offs of food carbon pricing, particularly as the UK develops its climate commitments.
Key measures
Disability-adjusted life years (DALYs) avoided; food-related greenhouse gas emissions (MtCO2-eq); tax revenues (AUD millions); changes in dietary consumption patterns
Outcomes reported
The study modelled the health, environmental and public finance impacts of incorporating greenhouse gas emissions pricing into food commodity prices. It measured diet-related disease burden (DALYs avoided), food-related emissions reductions, and tax revenues generated.
