Dietary change is necessary to fight climate change. The burden of changing diets cannot be left to the individual. Research has shown government policy plays a critical role in shaping what we eat (as well as individual drivers such as taste, cost and convenience). Policy action by government (information, regulation, taxes, subsidies) would incentivise the food industry and individuals to make more sustainable food decisions, which would lead to long-lasting behaviour change and address broader questions of social and environmental justice.
