Summary
This study used integrated economic, environmental and health modelling to estimate the impacts of introducing a carbon price ($23/tCO2-eq) into Australian food commodity prices. The analysis found that such a policy could simultaneously reduce diet-related disease burden (49,500 avoided DALYs), lower food-system emissions by 6% (2.3 MtCO2-eq), and generate substantial public revenue ($866 million), suggesting climate policies in the food system can align with public health objectives.
UK applicability
The findings are broadly relevant to UK climate and health policy discourse, though direct applicability requires adjustment for UK dietary patterns, food system emissions profiles, and elasticity estimates. The methodological framework may be transferable for modelling carbon pricing policies in the UK food system, though absolute outcomes would differ substantially.
Key measures
Disability-adjusted life years (DALYs) avoided; food-related greenhouse gas emissions (MtCO2-eq); tax revenue ($AUD million); consumption changes in response to price elasticity; disease burden across 11 disease states and 7 diet and weight-related risk factors
Outcomes reported
The study modelled the impact of a carbon price ($23 per tonne CO2-eq) applied to food commodities on dietary shifts, disease burden, greenhouse gas emissions reductions, and public revenue generation in Australia. It quantified avoided disability-adjusted life years (DALYs), emissions reductions (MtCO2-eq), and tax revenues from the policy intervention.
