Using structural materials like steel or cement comes at a high cost in dollars and CO2 emissions, with building construction accounting for an estimated 40% of emissions. Instead, scientists have figured out a way to engineer wood to trap carbon dioxide through a potentially scalable, energy-efficient process that also makes the material stronger for use in construction. They have done this by incorporating molecules of a carbon dioxide-trapping crystalline porous material into wood.
