Life Cycle Assessment (LCA) is a tool to calculate greenhouse gas (GHG) emissions of dairy production. A survey was conducted in 20 dairy farms at the governorate of Sousse. The present study aimed to evaluate environmental impact of milk production at the farm regarding GHG emission and energy consumption. In the 20 dairy farms total GHG emissions resulted in a mean of 0.63±0.2 kg CH4 /Kg ECM and forage can contribute with a means 0.35 Le KgCO2eq/DM. The main reductions in GHG emissions per kg of FPCM started from 2347kg per cow per year and then the reduction slowed down to stabilize at around 6127 kg FPCM per cow per year.

Keywords: Life cycle analysis, mitigation, carbon footprint, milk corrected.
