• Current research findings underscore the existence of interactions between climate change and food security. Substantive evidence indicates that dietary practices in the US not only contribute to climate change but also that the ramifications of climate change pose significant threats to food security. This paper seeks to clarify whether and to what extent a shift from the standard American diet to a plant-based diet can yield substantial contributions to sustainability in all three dimensions, especially considering altered agricultural conditions precipitated by a changing climate. Furthermore, it explores the extent to which this transition can contribute to the implementation of specific Sustainable Development Goals (SDGs) outlined in the Agenda 2030, as well as the limitations of this approach. Subsequently, this thesis examines the impediments that hinder the widespread adoption of a plant-based diet within society. It evaluates initiatives aimed at the promotion of plant-based diets within the US. Based on source research, a case study on the promotion of plant-based nutrition in California serves to deepen relevant insights. Grounded in findings from this case study, possible viable solutions and recommendations for the implementation of more sustainable nutrition models are subsequently developed.
