 This paper examines the political challenges associated with reducing red and processed meat, RPM, consumption. It highlights the influence of powerful actors such as business and industry groups, governments, intergovernmental organizations, and civil society. These actors have conflicting interests and asymmetric power relations which can lead to policy inertia. Additionally, the paper discusses how ideological beliefs such as carnism and neoliberalism can also be obstacles to RPM reduction.
