How trees offer a healthy and more liveable urban environment
Trees provide shade and reduce temperatures around them. Clusters of trees are effective to reduce urban heat islands in cities. One mature tree can produce the same cooling effect as 10 air conditioners.
Next to this, trees filter polluted air. One mature tree can filter 25 kg of pollutants, remove 22 kg CO2 and produce oxygen for two human beings. In streets and public space trees have a positive and calming effect.
