The big clean-up in the atmosphere
If we want to achieve our climate goals and prevent irreversible changes to the Earth's climate system, we not only need to curb our greenhouse gas emissions, but also remove excess man-made CO2 from the atmosphere. This is the aim of a new large-scale research initiative by Empa, Mining the Atmosphere. Peter Richner, Deputy Director of Empa, explains how to do this while creating a completely new economic system in the process. A new NEST unit, Beyond Zero, is also dedicated to CO2-negative technologies, as is the current issue of the research magazine Empa Quarterly.
