The threatening accumulation of carbon dioxide in the Earth’s atmosphere — due in large part to industrial activity — is fundamentally a big “waste-management problem,” says Fulton Schools Professor Klaus Lackner, emphasizing that it’s the responsibility of those who put the CO2 into the air to take it out. Some of the major corporations among those whose operations contribute to CO2 buildup are now looking at ways they can help deal with the problem. One potential fix is carbon-capture technology that Lackner and his colleagues at ASU’s Center for Negative Carbon Emissions are developing. The center’s “mechanical trees” are able to filter CO2 from ambient air.
