Trees made of moss soak up as much pollution as 275 trees in new London installation

This article originally featured in The Skylark’s newsletter and was written as a condensed news in brief.

London has finally installed three permanent “City Trees” in Leytonstone, a small move that hopes to see more of the pollution filtering devices appear across the capital. The “trees” are actually large towers filled with a variety of moss which absorb CO2, nitrogen oxides and particulates to produce oxygen. The towers have their own irrigation systems and can collect data on the surrounding environment. Each tower has the air cleaning capacity of 275 regular trees, making them extremely powerful in areas of high pollution in dense areas. A similar trial of the trees was conducted in the West End in 2018 on a temporary basis as the technology was perfected.
