Beyond electricity: Is hydrogen the key to greener smelting and refining?
*Please note that this report only includes an Excel data file if this is indicated in "What's included" below
Report summary
This analysis, conducted using Wood Mackenzie’s Emissions Benchmarking Tool (EBT), reveals the emission profiles of critical metals. The coal required for metallurgical reactions in ironmaking drives 93% of the global greenhouse gas (GHG) emissions from the iron and steel industry. On the other hand, 62% of non-ferrous metal production emissions are tied to electricity produced on-site or from the grid, underlining the urgent need for green energy.
