The nominating institution UCLA on the breakthrough: 

The production of ordinary portland cement (OPC), the binding agent used in concrete, accounts for 9% of global CO2 emissions. Our breakthrough technology, CO2Concrete, replaces OPC with a reinvented binder that “absorbs” CO2 upon exposure to flue gas waste streams, reducing CO2 emissions. CO2 from the waste flue gas stream is converted into solid carbonate minerals and stored in CO2Concrete construction products. CO2Concrete has a 75% lower carbon footprint than traditional OPC-based products.
