Klaus Lackner’s approach to slowing global warming is to clean up the atmosphere—literally. In his lab at Columbia's Engineering School, Lackner is working on technology to scrub carbon dioxide from the air, reducing levels of the harmful greenhouse gas that plays a major role in the increase of the Earth’s temperature.
“We need ways of getting the carbon dioxide, which is emitted by the combustion of fossil fuels, back,” says Lackner, the Ewing and J. Lamar Worzel Professor of Geophysics in the Department of Earth and Environmental Engineering, and the director of the Lenfest Center for Sustainable Energy at the Earth Institute.
“In the long term, we need to collect so much carbon dioxide to solve the climate change problem, and the greenhouses are a step on the way,” Lackner says. “Our goal is to use this to demonstrate you can really capture carbon dioxide and that you can do it at an affordable level.”
