Abstract

This paper explores the global feasible supply of steel and cement within Paris-compliant carbon budgets, considering uncertainties in infrastructure deployment. Despite substantial growth in recycling and hydrogen-based production, the feasible steel supply will only meet 55–85% of baseline demand in 2050, and cement supply is even more uncertain, meeting only 22–56%. This necessitates rapid infrastructure expansion and preparedness for deployment failures, emphasizing the urgency of demand-side actions and resource efficiency.
