A net-zero economy will require marketable, large-scale, and energy-efficient solutions to capture carbon dioxide (CO2). For the greatest effects, these would be implemented at high-emitting locations, such as power plants, metal, cement, and chemical refineries. However, this is more easily said than done.

Despite the challenges associated with developing feasible and practical solutions, researchers at the University of Calgary have come up with a promising metal organic framework (MOF) called CALF-20 that can selectively capture CO2 in large quantities and is already finding application in industry.
