how trees clean the air in London

trees remove tons of air pollutants in London

doc-titleEstimating the removal of atmospheric particulate pollution by the urban tree canopy of London, under current and future environments
quoteA paper published this month in the journal ‘Landscape and Urban Planning’ indicates that the urban trees of the Greater London Authority (GLA) area remove somewhere between 850 and 2000 tonnes of particulate pollution (PM10) from the air every year. ... One of the paper’s authors Professor Gail Taylor explains: "Trees have evolved to remove CO2 from the atmosphere, so it’s not surprising that they are also good at removing pollutants. Trees which have leaves the whole year are exposed to more pollution and so they take up more."
