Much of the world’s timber is immediately burnt or turned into paper. This releases huge amounts of carbon dioxide into the atmosphere. The Bank of Norrland is a concept meant to instead store it for later, more ecologically friendly purposes. Created by Anders Berensson Architects for the exhibition Architectures of Transition, the proposed structure would be a cubic kilometer in size, making it the world’s largest timber structure and the largest man-made carbon dioxide storage facility. The exhibition will continue through March 2022.
