Abstract: As a champion of urban ecologism and sustainability, Stefano Boeri Architett has always placed nature and trees at the heart of its research projects. With the completion of Vertical Forests in Milan, and Huanggang and Nanjing, China, they hope that these towers will not only be an important driving force in improving the natural environment of the city, increasing biodiversity and contributing to the achievement of the country's carbon peaking and carbon neutrality goals, but will also offer endless possibilities for cities’ development in the future.
