An extensive look at a variety of ways that scientists and engineers are  proposing as effective ways to combat the threatening impacts of climate change include new technology developed through work led by  Fulton Schools Professor Klaus Lackner, a professor in the School of Sustainable Engineering and the Built Environment, part of the Fulton Schools, and director of ASU’s Center for Negative Carbon Emissions. A forest of mechanical trees that can employ carbon-capture technology could significantly reduce harmful carbon dioxide in the atmosphere more quickly than natural trees can. The first mechanical tree was erected and instead on ASU’s Tempe campus in 2002.
