Abstarct: Nowadays, Iran is one the developing countries with good aspect ‎on development. One of the important issues on sustainable ‎development is getting maximum green and clean energy with ‎full caring of environment. So, the first thing to do for increasing ‎efficiency and productivity of measurement is analyzing, ‎planning and improving of performance in desired sections In ‎this research, using the fundamental applications of data ‎envelopment analysis‏ ‏and assumptions of disposability and the ‎creation of technical and environmental efficiency and ‎productivity and optimization of 12 natural gas refineries.‎‏ ‏In this ‎research, the input axis approach was used in the units of the ‎natural gas refinery from two inputs and two outputs. Results of ‎models and efficiency index shows technical performance and ‎efficiency of Fajr (KANGAN) and Khangiran ‎‎(HASHEMINEJAD) refineries for 12 natural gas refineries ‎between 1388 -1394‎‏.‏‎ However, by calculating Malmquist Index ‎for natural gas refineries shows half of them were have positive ‎efficiency index and others have negative efficiency index in the ‎years of investigation. Malmquist Index in that time table is ‎‎1.124 because of 0.984 technical performance productivity and ‎‎1.142 technological productivity. It is necessary to utilize data ‎analysis and use available potentials, production and efficiency ‎in the economics of production‏ ‏and environmental efficiency of ‎natural gas refineries and gas power plants should have major ‎increase‏.‏
