In this paper, ability ofgreen roofs in absorbing four air pollutants (PM10, SO2, NO2, and CO2) in Tehran wasvaluated. First, the potential of 1 m2 of a hypothetical green roof in Tehran in absorbingPM10 and SO2 during 1 year was estimated using a dry deposition model. Absorbingpotential of green roof for NO2 and CO2 was taken from other studies. Next, the reductionof each air pollutant was valuated using replacement cost method. Then, results weregeneralized to the total roof areas of the residential buildings in Tehran for the green roofslife span. Estimations showed that value of green roofs covering an area of 94,093,625 m2in reducing PM10, SO2, NO2, and CO2 during 50 years in Tehran will be 506,361,775 $.
