Can you put a price on our local vegetation?

Overall, an estimated 1.4 billion kg of air pollutants were removed by woodlands, plants, grasslands and other UK vegetation in 2015, according to a study produced for the UK Natural Capital accounts by the Centre for Ecology and Hydrology.

To put this in context, over five times as much PM2.5  (fine particulate matter with a diameter of less than 2.5 micrometres, or 3% of the diameter of a human hair) was emitted in the UK in 2015, than was removed by vegetation in 2015.

This pollution removal saved the UK around £1 billion in avoided health damage costs3. It is estimated there were 7,100 fewer lung and heart-related hospital admissions, 27,000 fewer life years lost and 1,900 fewer premature deaths in 2015 as result of nature providing this service.

Trees, in particular, provide a wide range of services and account for most of the volume of air pollutants absorbed by natural vegetation in the UK but can have adverse effects also4.
