How can your early-stage innovative technology solution solve the world’s most pressing social and environmental problems?



40% of global energy consumption and CO2 emissions originates from buildings. By 2050, 3.5 billion people will shift into urban areas, which means more construction/buildings, more traffic, less space leading to a lot more air pollution. PurCity's solution is a patented, sustainable, and highly efficient self-cleaning air purification system (GapS) that directly captures carbon (CO2), cleans air and produce sellable CO2 byproducts. Each 3 m­2 of GapS panels is estimated to directly capture 22 Tons of CO2/building (equivalent to 1013 mature trees carbon capture/year) as well as contributing to saving 10-20% Energy Consumption in the building annually.
