The purpose of this research was to determine the energy-economic balance and greenhouse gas (GHG) emissions of avocado production. This research was carried out during the 2018–2019 production season in Gazipaşa district of Antalya province in Turkey. The agricultural inputs and outputs used in avocado production were calculated to define the energy-economic balance and GHG emissions. According to our research findings, the energy inputs in avocado production were calculated as 18,330.24 MJ ha−1 (39.96%) chemical fertilizers energy, 10,828.80 MJ ha−1 (23.60%) electricity energy, 6696.27 MJ ha−1 (14.60%) irrigation water energy, 4955.28 MJ ha−1 (10.80%) diesel fuel energy, 1800 MJ ha−1 (3.92%) farmyard manure energy, 1497.44 MJ ha−1 (3.26%) human labour energy, 1036.80 MJ ha−1 (2.26%) machinery energy, 512.78 MJ ha−1 (1.12%) transportation energy and 217.58 MJ ha−1 (0.47%) chemicals energy. Total input energy was 45,875.19 MJ ha−1. The energy output value of avocado fruit was calculated as 100,617.85 MJ ha−1. Energy use efficiency (EUE), specific energy (SE), energy productivity (EP) and net energy (NE) values were, respectively, 2.19, 4.03 MJ kg−1, 0.25 kg MJ−1 and 54,742.67 MJ ha−1. The consumed total energy input in avocado production could be classified as 52.27% direct, 47.73% indirect, 21.78% renewable and 78.22% non-renewable. Total GHG emission was 6145.31 kg CO2‑eqha−1 for avocado production with the greatest share for electricity (29.43%). The GHG ratio in avocado production was 0.54 kg CO2‑eqkg−1. The benefit–cost ratio was calculated as 1.81 for avocado fruit production.
