摘要:Climate change is now more important than before, based on many evidence, humans were affecting on changing Earth’s climate. The atmosphere and oceans have warmed, by sea-level rise, a strong decline in Arctic ice sea, and other climate-related changes. The aim of this study was to calculate some important greenhousse gasses concentration such as CO2, CH4, N2O in AL-Nahrawan suburban -Baghdad city -Iraq. Geographic Information System (GIS) was utilized to map greenhouse gasses dispersion in AL-Nahrawan bricks factory. From GIS distribution maps for CO2, CH4, N2O, it was found that the value of these gasses were changed from one location to another according to the quantity of fuel used in bricks factory, Where the value of emitted CO2ranged from (695 -854 tones), value of N2O ranged from (1.905 - 2.318 tones), and finally value of CH4ranged from (0.286 - 0.347 tones).
