Introduction: Replacingfuel oil with natural gas in brick kilns is one of the effective ways to reduce air pollution as well as the cost of the furnaces maintenance. The aim of this study isto estimate reduction of air pollutants resulting from brick kilns functioning with natural gasin Yazdprovince. Methods: In this descriptive-survey research, we estimated consumption of the fuel oil in the brick kilns with considering the usage of fuel oil instead ofnatural gas at the studied time usingthe heating value of the fuel oil and natural gas consumption of46 gas-makingbrick kilnsin the Yazd province from 2008 to 2012.Then the produced air pollutants from the natural gasconsumption andproduced air pollutants by assuming consumption of the fuel oil instead of natural gasin the brick kilnsat this timewere compared and the rate and value of reduction in each one of pollutants weredetected. Finally, the value of budget savings and social costs of the environmental damage resulting from the usage of natural gas instead of fuel oil were calculated on the basis ofusing the price per liter of fuel oil and natural gas per cubic meter as well as the studies by the World Bank and the Environmental Protection Agency of Iran. Results: The results indicated that emission of air pollutants is reduced up to130485.71 ton in CO2 and 8695.63 ton in other pollutants by run-by-gas brick kilns in the studied area since 2008 – 2011 (end of September). In addition,the amount of budget saving is estimated as 187.578 billion Rials by replacing the gas fuel inthe brick kilns and 129.380 billion Rials in the social and environmental costs from emission of pollutantin the years studied. Conclusion: For positive economic, environmental and health-related effects resulting from this program, planning and financial support for running-by-gas of other brick kilnsseems to be urgent.
