Six percent of global CO2 emissions—4.4. billion tonnes per year—are currently produced by the steel and aluminum industry. In an overview article for the journal Nature, Dierk Raabe, Director at the Max-Planck-Institut für Eisenforschung in Düsseldorf, and scientists from MIT in Cambridge Massachusetts outline how the immense CO2 footprint in metal production and use can be reduced. On the one hand, they propose measures that can be implemented quickly and with comparatively little effort. On the other hand, they formulate long-term goals that can be achieved only with the help of comprehensive basic research.
