There are significant costs and criticism standing in the way of implementing direct air capture technology to help reduce one of the potentially more destructive causes of climate change. Direct air capture systems remove carbon dioxide from the atmosphere. Carbon dioxide comes from burning fossil fuels and is a major source of the greenhouse gas emissions driving a long-growing climate crisis. More than two decades ago, Klaus Lackner was among the first to recognize the technology as a potential remedy for the problem. Today, as a Fulton Schools professor, he directs ASU’s Center for Negative Carbon Emissions, overseeing research to make air capture affordable and a viable technology in the field of sustainable energy infrastructure design.
