Dietary Behavior as a Target of Environmental Policy: Which Policy Instruments Are Adequate to Incentivize Plant-Based Diets?

Abstract

Meat consumption causes major damage to the environment, such as the pollution of air, water, and soil, and contributes significantly to biodiversity loss and climate change. To reach environmental and climate targets, agricultural production methods need to be addressed politically. However, dietary behavior also needs to change. This is especially the case in Western countries with unsustainably high meat consumption, such as Germany. Based on a systematic analysis of the literature of different disciplines, the article examines the following: (a) Factors influencing food behavior; (b) Policy instruments effectively contributing to behavior change; (c) Potential problems with regard to their political feasibility. Using Germany as an example, the analysis shows that only a combination of measures is promising to achieve a reduction in meat consumption—both in terms of effectiveness as well as political feasibility. Instruments need to change contextual conditions in a way that makes sustainable nutritional choices the easier ones. In the longer term, education programs and campaigns can help to change basic influencing factors such as norms or values. And, in the short term, these factors can be activated and become relevant for action in the respective decision-making situations.
