- Abstract (EN)
- Agriculture causes large parts of global Greenhouse gas emissions (GHGE), with livestock contributing the greatest share. Livestock-based foods are thus associated to higher GHGE than plant-based foods. Additionally, they are harmful to health when consumed in excess. The focus of this work lies on determining the potential to reduce agricultural GHGE when healthy diets and lower meat intakes were adopted in the EU. lt is also examined how much feed crops and pastures would become available for the production of biofuels. An emission tax and an emission trading system are also examined. To assess the complex interactions in the agricultural sector, a modified version of the European Forest and Agricultural Sector Optimization Model (EUFASOM) is used. The results show that a halved meat intake could reduce agricultural GHGE by a quarter and biofuel production could increase eightfold. The political instruments lack effectiveness though. The GHG tax has a low impact on nutrition and roughly 50% emission leakage. Emission trading has only a moderate effect on nutrition and over 100% emission leakage.
