Increasing urbanization brings about several sustainability challenges for its citizens. Among many, air quality is probably the most important and common one due to limitation in natural sources and the increased use of energy in buildings and transportation. Many cities have considered including urban vegetation in their sustainable development plans to abate the effects of climate change as well as for beautification of neighborhoods to motivate positive behavior of their citizens. Trees have been known for cleaning air by converting carbon dioxide into oxygen reducing their impact on health and materials. Moreover, trees can directly affect particulate matter concentration by (1) removing particles, (2) emitting particles or (3) by the re-suspension of particles on the plant surface. This study presents the air quality impacts of urban vegetation in the city of Doha (State of Qatar) under arid conditions, which can be mainly described with high temperature, high relative humidity and high concentration of particulate matters originating from multiple sources. Three abundant local urban tree species were selected for this study, namely Acacia (Wattles), Ziziphus (Sidra) and Phoenix dactylifera (palm date) trees. Their environmental economic value (EEV) was evaluated and compared based on their capability to abate gaseous and particulate pollutants utilizing the application of the National Tree Benefit Calculator. To this end, Acacia was found to have the highest EEV under Doha city’s weather conditions.
