Hi-tech trees could be installed in Aberdeen to improve air quality

Hi-tech “trees” could be installed across Aberdeen to help rid the city of pollution.

The City Tree is a four-metre tall panel of moss and greenery which can filter out pollutants, such as nitrogen oxide from vehicle emissions to help improve air quality.

Designed by German firm Green City Solutions, each unit acts as the equivalent of 275 trees, removing around 240 tonnes of carbon each year.

The technology, which costs around £20,000 per installation, can also offer a quiet place to sit with benches on either side – and even a wi-fi signal.

The installation is self-powering and self-watering and has been designed to withstand deliberate vandalism and graffiti.

SNP councillor Ciaran McRae has filed a motion to instruct council officers to look at the feasibility of siting the trees in places where “immediate improvements in air quality are deemed necessary”.

The motion will be considered at the next meeting of full council on Monday.
