The main objective of the present work was to analyze the impact of changing different factors in the carbon footprint calculation of milk. Considering the results of a meta-analysis by Belanche et al. (2020a, b), enteric methane emissions per day (− 8.8%), ECM performance (+ 4.1%), and feed efficiency were changed by + 4.4% using the essential
oil blend Agolin Ruminant. The results of the current study showed that there is a positive effect of Agolin Ruminant on the carbon footprint of milk (kg CO2eq/year) in relation to the amount of ECM produced (kg CO2eq/kg ECM) of 10%.
