The effect of increasing milk yield per cow on greenhouse gas (GHG) emissions and on other side effects was quantified. System modelling and life cycle assessment were conducted. A special focus was given to the close interlink of milk and beef production and to uncertainties in GHG modelling. Greenhouse gas emissions and land use impact of increasing milk yield/cow differs, depending on the amount beef that has to be compensated for. System approaches that go beyond the boundary of the dairy farm gate are necessary to avoid shift of GHG emissions between production systems or countries.
