Buildings across 12 U.S. cities could store 134,863 million metric tons of carbon dioxide for the long term. Urban buildings can store carbon in their wooden components and through concrete carbonation, a naturally occurring process by which carbon dioxide reacts with cement-based materials, gradually accumulating more carbon over its lifetime in use. Carbon stores in wood building materials could be maintained with the help of recycling, preservation, and adaptive reuse policies.
