In 2015, the NGOs PUSCH, WWF and others published a comparison of food standards on the Swiss market in order to help consumers make informed purchasing decisions. This comparison is based on a multi-dimensional evaluation through indicators in environmental, social and governance aspects (Herrmann et al., 2015). The goal of this research project is to investigate how meaningful it is to extend the 2015-evaluation of food standards with measurements of their environmental impacts. Second, the goal is to analyse existing methods of environmental impact assessment in the agro-food sector and evaluate the potential and bar-riers for their integration in the comparison of food standards.The challenge is to improve the evaluation of environmental aspects in the comparisons with a sound method that gives meaningful results at reasonable costs.
