the smog levels in London are worrisome. Just think that in 2018, in just one month, the city has already reached and exceeded the levels of legal pollution envisaged by the EU.
To try and reverse this trend, the administration relied, among other things, on the solutions of the German company Green City Solutions, installing a special absorbing "smog tree" in the Piccadilly Circus area.
The City Treen is a tool that performs different functions: it acts as a bench, sucks in smog and monitors the levels of city pollution. It works thanks to a combination of plants and moss that have the power to remove dust, nitrogen dioxide and ozone from the surrounding environment.
The technological tree is powered by solar panels and is connected to the Internet; thanks to the surveys carried out every day, it allows to know in real time what are the levels of smog, soil moisture, temperature and water quality.
Despite its small size, City Tree alone carries out the work of 275 real trees, filtering in a year about 250 tons of carbon dioxide and other harmful micro-particles typical of the urban environment.
The installation of this anti-smog bench in London was financed by Crown Estate (the British Crown-owned finance company) and the City of Westminster. "There is no simple solution, so in addition to trying to reduce emissions from our homes and the number of vehicles in circulation, we also want to learn from new technologies," said Crown Estate CEO James Cooksey.
By adopting this initiative, London follows the example of cities that have already resorted to the City Tree: Paris, Oslo, Newcastle, Amsterdam, Berlin, Brussels, Hong Kong and Drammen (Norway).
