ASU is recognized as one of the U.S. universities where researchers are making the most significant progress in endeavors to curb the carbon emissions that pose an environmental threat. Much of that work is being done through by research and development projects in the Center for Negative Carbon Emissions, directed by Klaus Lackner, a professor in the School of Sustainable Engineering and the Built Environment, part of the Fulton Schools. The center is at the forefront of advances in carbon capture technologies, in particular an innovative carbon management cycle designed to capture carbon directly from the air. The center’s “mechanical tree” technology is much more effective than natural tress at removing carbon dioxide from the atmosphere.
