Residents will breathe easier as new hi-tech CityTrees set to arrive in Watford

As part of the Chalk Hill development, Watford Borough Council has arranged for the developer to introduce a large green free standing installation called a CityTree, which will remove pollutants from the air in Watford.

At 4metres tall, nearly 3metres wide and 2metres deep, the sleek and trendy CityTree is said to remove as much pollution as around 275 real trees. The installation is made up of moss cultures, which have a much larger leaf surface area than any other plant and can capture more pollutants.

Elected Mayor of Watford Peter Taylor said: “I’m passionate about making our town more sustainable and so I’m delighted to be welcoming the town’s first ever pollution-stopping CityTree. We will continue to look at how innovative and forward-thinking ideas can have a positive impact on the environment. This scheme will help to improve air quality in that area, which is good news for everyone.”

The huge surfaces of moss installed in each CityTree can remove dust and nitrogen dioxide from the air. It requires very little maintenance and solar panels power its electrical requirements and rainwater collected is used for irrigation. The manufacturer estimates that each CityTree can remove around 240 tonnes of Carbon Dioxide (greenhouse gas) every year.
