To date street tree have planted with their partners 1400 street trees in central London. This year street tree have planted over 600 trees in the boroughs of Westminster, Camden and Tower Hamlets. And we are proud to announce that street tree will be planting a pair of trees for LTEC in the London Borough of Southwark (close to our City Hall venue).

Benefits of Trees

Otherwise ugly areas can be transformed by the introduction of several species of trees.

With growing concern about air pollution, trees are an excellent producer of Oxygen. The main way that a tree combats pollution is through acting as a sink or receptor and catching suspended particulate matter (s.p.m.) on it's leaf surface. This helps remove a number of pollutants including Nitrogen Oxides, Sulphur, Ammonia and Dust Particles. At the end of the growing season the leaves are then discarded by the tree.

Recent pollution studies in Athens (Aspropyrgos), a highly polluted city, suggest that a tree absorbs carbon dioxide but not carbon monoxide. They also suggest that ozone in the immediate environment is caused when heat fuses with pollutants and can be reduced by providing tree cover to filter out solar radiation and reduce temperature.

Furthermore research suggests that, taking into account variables such as climate, species, location, etc., it is difficult to formulate standards that quantify rates of pollution absorption. Although the most effective way to combat pollution is at source, it is the case that trees do have a positive effect on the environment and do reduce levels of pollutants.

Tree Economics

Trees add value. First of all they can act as 'green magnets' attracting businesses and their employees into an area. Secondly they can literally add up to 15% to the values of property in a tree lined street. Furthermore trees have value for local communities by landscaping the urban environment, filtering noise and screening.
