In this study, energy use patterns and the functional relationship between energy inputs and output for pomegranate production were investigated in Antalya province in Turkey. It further objective to identify greenhouse gas (GHG) emissions in pomegranate production. Data were obtained from 75farms using face-to-face interview method. The results indicated that 50,605.5MJ ha(-1) of total energy input was required for 76,252.3MG ha(-1) pomegranate energy output. 1.51 unit energy output was provided by using 1unit energy input. 1unit energy output and 1kg pomegranate require 0.66 unit and 2.57MJ energy input, respectively. The average CO2 emission amounts were also calculated to be 1.73t CO2 per hectare and 88.1kg CO2 per 1000kg pomegranate production. Electricity, fertilizers and pesticides were the highest contributors to GHG emissions. Both total energy input usage and GHG emission amounts have been found to be decreasing as the farm size increases. Increasing scale of pomegranates orchards will not only increase energy efficiency and productivity but also decrease environmental pollution and damages. The regression analysis revealed that, excessive use of machinery and fuel inputs results in adecline in energy production in pomegranate.
