During a parliamentary evening, Aaron Scheid presented an analysis of the environmental economic impacts of animal-based food production on 12 December 2023. Focusing on external environmental costs, particularly greenhouse gas and ammonia emissions, and with quantitative evidence of costs in the billions, Scheid proposed tax incentives to internalize these costs. His presentation emphasized the need for a comprehensive strategy that considers political, social, and economic aspects, and provided policy options for a sustainable food policy.

Animal products are an essential part of today's German diet, but they are associated with a variety of environmental problems, such as global warming, eutrophication of soils and waters, etc.. These cause external costs. The study, co-authored by Aaron Scheid and Benjamin Görlach of Ecologic Institute, estimates these external costs for animal products and examines policy measures to address them.

At this round table, organized by the TAPP (True Animal Protein Price) Coalition, the panel discussed a study that shows that true costs for animal products that takes into account all societal costs has a positive impact on society. The study was co-authored by Aaron Scheid and Benjamin Görlach from Ecologic Institute.

The consumption of dairy, eggs and meat causes damage to the environment in various places in the supply chain, such as climate change, eutrophication and the emission of harmful substances such as ammonia (which contributes to nitrogen problems) and particulate matter. The TAPP Coalition (True Animal Protein Price Coalition) requests a European-oriented policy proposals to pass on the price of dairy, eggs and meat so that it reflects the actual costs to society and to calculate these for economic and environmental effects for the EU-27 involving two case studies for Germany and France.
