Air Quality

Poor air quality in urban areas has accelerated with the increase in human activity since the Industrial Revolution and it continues to be a serious issue in our towns and cities. Trees contribute to improving air quality by reducing air temperature, removing pollutants from the air, absorbing them through the leaf surfaces, and by intercepting particulate matter (e.g. smoke, pollen, ash and dusts).

The trees in Islington remove an estimated 6.8 Tonnes of pollutants each year. This is equivalent to the annual emissions of over 4000 cars.
