Obesity and climate change mitigation in Australia: overview and analysis of policies with co-benefits.

OBJECTIVE:

To provide an overview of the shared structural causes of obesity and climate change, and analyse policies that could be implemented in Australia to both equitably reduce obesity rates and contribute to mitigating climate change.

METHODS:

Informed by the political economy of health theoretical framework, a review was conducted of the literature on the shared causes of, and solutions to, obesity and climate change. Policies with potential co-benefits for climate change and obesity were then analysed based upon their feasibility and capacity to reduce greenhouse gas emissions and equitably reduce obesity rates in Australia.

RESULTS:

Policies with potential co-benefits fit within three broad categories: those to replace car use with low-emissions, active modes of transport; those to improve diets and reduce emissions from the food system; and macro-level economic policies to reduce the over-consumption of food and fossil fuel energy.

CONCLUSION:

Given the complex causes of both problems, it is argued that a full spectrum of complementary strategies across different sectors should be utilised.

IMPLICATIONS:

Such an approach would have significant public health, social and environmental benefits.
