Greenhouse gas (GHG) emissions per unit of milk production are characterized by large fluctuations from year to year, mainly affected by feed production conditions. In the period 2005−2018 there was no clear reduction trend (despite a clear trend over the longer period 1985−2018). Values after 2014 show a favourable trend towards the target value (0.786 kg CO₂ equivalent in 2020). Possible difficulties in achieving the goal will be due to, inter alia, the unrealized activity entitled "Feed analysis and calculation of diets for cattle and/or small ruminants" from the original proposal of the agri-environment-climate payments measure of the 2014−2020 Rural Development Programme.
