Carbonate formation in waste from the steel industry could constitute a non-trivial proportion of global requirements to remove carbon dioxide from the atmosphere at potentially low cost. To constrain this potential, we examined atmospheric carbon dioxide sequestration in a >20 million tonne legacy slag deposit in northern England, UK. Carbonates formed from the drainage water of the heap had stable carbon and oxygen isotope values between-12 and-25 ‰ and-5 and-18 ‰ for δ 13 C and δ 18 O respectively, suggesting atmospheric carbon dioxide sequestration in high pH solutions. From the analyses of solution saturation states, we estimate that between
