A material revolution replacing cement and steel in urban construction by wood can have double benefits for climate stabilization, a new study shows. First, it can avoid greenhouse gas emissions from cement and steel production. Second, it can turn buildings into a carbon sink as they store the CO2 taken up from the air by trees that are harvested and used as engineered timber. However while the required amount of timber harvest is available in theory, such an upscaling would clearly need most careful, sustainable forest management and governance, the international team of authors stresses.
