The best part about CityTree, Green City Solutions claims, is that it’s capable of providing the same environmental benefit 275 actual trees would. It’s able to absorb some 250 grams of particles per day, removing 240 metric tons (or tonnes) of carbon dioxide every year. “Moss cultures have a much larger leaf surface area than any other plant. That means we can capture more pollutants,” Zhengliang Wu, co-founder of Green City Solutions, told CNN. Wu was part of a team that conceptualized the idea and installed a CityTree in Brussels four years ago. Each has Wi-Fi-enabled sensors capable of measuring the quality of air around it. Since it takes up a relatively small space and can be installed fairly seamlessly in parks (even accompanied by benches), CityTree has proven to be an efficient and fairly cost-effective (they cost around $25,000 each to install) strategy for cleaning the air. Global air pollution continues to be a huge problem, as the World Health Organization notes—especially in urban centres. This is why Green City has already installed around 20 of their “trees” in cities throughout the world, including Oslo, Paris and Hong Kong. CityTrees are currently being installed in Modena, Italy and plans to introduce them within low-income countries that have high levels of pollutants—like India—are on the way as well. “Our ultimate goal is to incorporate technology from the CityTree into existing buildings,” Wu said. “We dream of creating a climate infrastructure so we can regulate what kind of air and also what kind of temperature we have in a city.”   image: Pixabay Read the full article
