One of the major environmental impacts of energy use is air pollutant emissions such as greenhouse gases. The aim of this study was to investigate the relation between energy consumption in small urban businesses and their air pollution in small urban businesses in the city of Qom in 2015.   In the first step, by referring to Qom chamber of trade, a list of all urban jobs from 67 trade :::union:::s was prepared and then, a total of 223 workshops were selected randomly and visited. Means consumption of electricity and gas were calculated by referring to the related gas and electricity offices in Qom. The amount of pollutants produced from energy consumption was calculated by using the software available at the Abraxas Energy website.   The results showed that the average monthly consumption of 9098.86 kwh and 41669.35 cubic meters of gas in the small businesses of Qom, on average produced 50.995 of carbon dioxide, 78.963 kg of lead compounds, 52.39 kg nitrogen compounds, 8.403 kg carbon monoxide, 5.02 kg volatile organic compounds, 1.996 kg nitrogen oxides, 1.781 kg mercury compounds and less than 1 kg per month particulate matter and SO2.   Any attempt for reducing energy consumption, in addition to its economic benefits, can be a basic measure to reduce environmental pollutants. Implementation of proper management plans for reducing electricity and gas consumption is a major step in this direction.

Furnaces as a major process of manufacturing brick and chalk are considered as one of the major sources of greenhouse gases. This study aimed to investigate the relationship between energy consumption of the furnaces of brick and chalk and environmental pollutant emissions in the city of Qom.
This descriptive study was conducted of year 2012-2015. General information and entrance permit were acquired by the respective unions in the city of Qom. Ten field visits randomly chosen from either chalk and brick manufacturers were conducted. In addition, further information regarding the energy consumptions from electricity and gas companies was obtained. The amount pollutants produced from the energy consumption were calculated by using software that available on the website: http//www.abraxasenergy.com/emissions.
The calculated emission of pollutants such as: carbon dioxide, nitrogen compounds, carbon monoxide, volatile organic compounds, Nitrous oxide, lead, particulates, sulfur dioxide, cadmium, mercury were 1001000, 1296.82, 185.7, 41.68, 16.69, 15.19, 14.42, 4.84, 2.4 and 0.316 kg/month, respectively.
Based on the level of pollutants which was higher than comparable industries, strategies such as: rationing fuel, forming an environmental monitoring committee and more efficient control of combustion and burner’s maintenance and application of air purification techniques for pollutants prior to their release through furnaces’ stack was recommended.
