Trees

Trees provide The Green City with a framework. With so many leaves, trees are very effective at filtering pollutants from the air. Deciduous trees such as Quercus robur (European Oak) are especially effective in absorbing gaseous pollutants such as ozone and nitrous oxide. Conifers such as Pinus nigra (Austrian Pine) lead the way in removing particulates from the air.

Using various tree species provides even more benefits: they are also...
