Despite an urgent need to reduce carbon dioxide emissions into the atmosphere to avert harmful environmental impacts, CO2 emissions continue to rise. Klaus Lackner, a professor in the School of Sustainable Engineering and the Built Environment, one of the Fulton Schools, is among the leading innovators in carbon capture technology that can remove CO2 from the air. The mechanical trees he has led the way in developing through work in ASU’s Center for Negative Carbon Emissions could significantly reduce the CO2, but it will take a vast deployment of Lackner’s technology to adequately reduce the growing threat to Earth and its inhabitants.
