Man-made air pollution is responsible for 4,800 deaths from heart attacks a year - Rebecca Smith, Medical Editor
TFL Case Study
The ANS LivingWall was installed on the side of a shopping mall and the plants were chosen for maximum impact on air quality.
Also on this scheme was the promotion of walking and cycling, as well as special paving designed to absorb harmful particles from the air.
Public transport was widely promoted on the scheme to reduce the number of cars and therefore the amount of pollution added.
