Negative Carbon Emissions

(40:50) Guest: Klaus Lackner, director of the Center for Negative Carbon Emissions at Arizona State University  The Center for Negative Carbon Emissions at Arizona State University has a lofty goal: to suck carbon dioxide out of the air to help prevent climate change. With global CO2 emissions reaching unsustainable levels, the team at ASU has developed a technology to “capture” carbon dioxide from the air. The CO2 could then be used by industries that need it, or disposed safely without entering the atmosphere.  “If you look at what we put out right now, it comes out to be 30 billion tons of CO2 a year," says Lackner.
