Extensive planting within cities is now widely recognised as a means of improving air quality. Therefore green roofs contribute to the reduction of a number of polluting air particles and compounds not only through the plants themselves but also by deposition in the growing medium itself. Good air quality plays a major role in the health of people living in urban environments.

People who live in concentrated urban areas are often exposed to high levels of pollution which unfortunately damage their health. Changing one roof to a green roof in a city may have limited impact however if green roofs became an accepted part of building practice the impact on air quality in cities could be huge. Researchers suggest policy planners could use green roofs in conjunction with existing. Less need for health care services result in societal cost savings.

On a wider scale green roofs improve air quality and help reduce the urban heat island effect a condition in which city and suburban developments absorb and trap heat. Green roofs provide shade remove heat from the air and reduce temperatures of the roof surface and surrounding air. A green roof or rooftop garden is a vegetative layer grown on a rooftop.

Of roofs with grass extensive green roofs is an effective alternative for significantly reducing the impact of urban air pollution. Good air quality plays a major role in the health of people living in urban environments.

Using green roofs in cities or other built environments with limited vegetation can moderate the heat island effect particularly during the day. Reduced urban heat island profile.
