The olive tree (<italic>Olea europaea</italic> L.), widely cultivated in the Mediterranean countries for olive oil and table olive production, has an important economic role.

In the climate change category, the results indicated that for production of 1 kg olives, a total of 0.249 kg CO2-Eq. were emitted to the atmosphere. Regarding the direct impact of production system, a total of 0.177 kg CO2-Eq. (71.5%) were emitted, followed by indirect impacts associated with raw material of the irrigation system (0.032 kg CO2-Eq. total, 12.7%), and electricity needed to pump ground water (0.012 kg CO2-Eq., 4.8%). In relation to inputs for production, the raw material for urea production contributed 0.013 kg CO2-Eq. (5.0%) of total emissions. To the best of our knowledge, this study was the first carried out in this region, and contributes to a better understanding of environmental impacts that will allow their minimisation and ensure olive orchard sustainability.
