Chicken always performs better than beef, as cattle rearing emits more CO2 than poultry farming. The Optigal brand has no bearing on this. At Optigal however, we rely on resource-efficient production methods. The climate-friendly nature of the farms now impacts the star rating: (see http://www.reise-des-optigal-poulets.ch/). This way, we can show that our own chicken is different to other chicken.
The relatively good three-star rating is primarily the result of Migros acquiring soy – an important raw material for chicken feed – from Europe and not from South America. The certified European soy for Optigal has a considerably better carbon footprint than the soy from South America.
