Cleaning our air

 

 

Energy Garden is contributing to London's great history of tackling air pollution by introducing plants on the London Overground. Native hedgerows and leafy ferns absorb floating particles, improving the quality of the air you breathe.

 

 

Hedgerows like the ones planted at Bush Hill Park and Willesden act as a screen to filter air pollution and noise.

At Penge West and Caledonian Road & Barnsbury, the first of many living walls are filled with plants to clean the air around the platform. 

London's air pollution is not a new problem.

 

In the 1950s we learned the hard way what happens when industrialisation goes unchecked. The great smog of 1952 encouraged the government of the day to introduce the Clean Air Act, dramatically improving air quality and the livelihoods of the capital's residents in a few short years.

The Act was a trailblazer, creating laws which today we would consider common-sense, such as enforcing the burning of smokeless fuels in residential areas. A little known fact is that proceeding the law, the London Plane Tree was introduced as a biological control for the Capital's pollution problem. These trees, now hundred-foot-tall giants dominating the parks and streets of the city, shed their porous bark regularly. As the bark absorbs nasty pollutants, these chemicals get returned to the earth via a natural process. 

 

The threat from air pollution is growing once again as we learn more about the harmful chemicals from diesel gas being burned on our streets. Energy Garden is joining the range of inspiring projects choosing to take this threat head on.
