Summary
This 2016 modelling study, published in Nature Climate Change, assessed the potential for emissions pricing of food commodities to reduce agricultural greenhouse gas emissions whilst simultaneously improving population health outcomes. Using integrated assessment and epidemiological models, the authors evaluated global scenarios of carbon pricing applied across major food products, estimating both climate mitigation potential and health co-benefits from altered consumption patterns. The work suggests that pricing mechanisms targeting high-emission foods could deliver dual climate and public health gains, though the magnitude of effects varies by region and pricing level.
UK applicability
The findings are relevant to UK policy discussions around carbon pricing and agricultural sustainability, particularly as the UK develops independent climate and food security strategies post-Brexit. However, the global model results require contextualisation to UK food system structure, existing subsidy regimes, and consumer price sensitivity before direct policy application.
Key measures
Greenhouse gas emissions reductions; changes in food consumption; diet-related mortality and morbidity; health impacts from shifts in dietary composition
Outcomes reported
The study modelled the effects of greenhouse gas emissions pricing applied to food commodities on agricultural emissions, food consumption patterns, and associated health outcomes at global scale. It quantified potential climate mitigation and health co-benefits from carbon pricing policies affecting food production and consumption.
