This paper provides a qualitative governance analysis of which regulatory options there are to align livestock farming with the legally binding environmental objectives, in particular the Paris Agreement and the Convention on Biological Diversity. Two innovative governance approaches are developed and compared: a cap-and-trade scheme for animal products and a livestock-to-land ratio. Both instruments are measured against the above-mentioned environmental objectives, taking into account findings from behavioural sciences and typical governance problems. Both approaches are generally suitable as quantity governance in animal husbandry if they are properly designed. In the end, a combination of both approaches proved to be particularly effective ecologically.
