A review of policy levers to reduce meat production and consumption

It is increasingly apparent that we require a substantial reduction in animal production and consumption for the sake of the environment and public health. In this paper, we conducted a systematic review to explore the policy levers available for governments to reduce animal farming and the consumption of meat. The policy levers generated by the review are categorised by four main types of interventions: Financial measures, Command- and-control, Informational, and Behavioural. First, we explore four financial measures: taxes on meat is the most-studied intervention, and the least publicly accepted in polling, sometimes being implemented indirectly via measures such as carbon taxes or rescinding VAT exemptions; subsidies for animal product alternatives are considered as a more publicly acceptable alternative approach, and would reduce long-term demand for meat by making alternatives more competitive; agricultural carbon trading schemes are discussed, and may represent a politically feasible way to hold livestock producers accountable for negative externalities; and buyouts of animal farms can be an impactful way to compensate producers to leave the industry, but must be done with care to avoid unintended social and market consequences. Second, we explore two command-and-control measures: regulating animal production with standards such as animal welfare requirements and health and safety rights for agricultural workers is amongst the most well-supported policies, and is an impactful way to ensure minimum standards of production are met; however, restrictions on animal consumption, such as meat–free days in public catering, are less publicly accepted. Third, we discuss three informational measures: food product labels, such as animal welfare or environmental impact labels, fulfil consumers’ expectations to have this information, and although there is limited evidence that they impact consumer behaviour directly, such labels may nonetheless incentivise producers to competitively improve; likewise, national dietary guidelines appear to have little direct impact on food choices, but can impact other institutions such as schools and medical institutions; policies on information campaigns can help or hurt meat reduction efforts, with some jurisdictions prohibiting meat advertisements, while others spend millions on campaigns to promote meat consumption. Fourth, we explore a range of behavioural measures which could be implemented in public catering settings and/or incentivised in food service, including presentation and positioning of meat- and plant-based dishes, and altering the food options on offer – we find that adding more high-quality plant-based options to menus and presenting these options as the default wherever the format allows are highly impactful and tractable behavioural policies that could reduce meat consumption. Informational and behavioural measures can complement traditional fiscal and command-and-control measures to reduce animal production and consumption. We discuss the implications for researchers and policymakers.
