Efficiency stagnation in global steel production urges joint supply- and demand-side mitigation efforts

P. Wang, M. Ryberg, et al.

Climate change mitigation in steel production faces challenges, as process efficiencies have improved by 67% since 1900, yet a 44-fold increase in annual production has led to a net increase in emissions. The stagnation of decarbonization since 1995 highlights the urgency for joint mitigation efforts to achieve Paris Agreement goals.
