Change in Construction Materials Could Transform Buildings Into a Global CO2 Sink Buildings can become a global CO2 sink if made out of wood instead of cement and steel. 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...
