Sustainability Challenges in the Global Steel Cycle
Iron/steel is the most widely used metal, and its production alone accounts for ca. 8% of global anthropogenic GHG emissions. Deep GHG emissions reduction in the steel industry is difficult and costly to implement, and steel production emerges as a bottleneck in curbing global warming to well below 2°C. To estimate future steel demand, levels of primary and secondary production, and GHG mitigation potentials, a model-based approach is necessary. Here, results from the first global scenario analysis for circular economy in the steel cycle and its GHG implications are reported. The overall emissions mitigation potential for different technological options in the steel industry is then discussed, and an outlook on demand-side material efficiency strategies and their implementation in the EU emissions trading system is given.
