Sustainability In The Metal Industry Statistics

Steel is getting more efficient fast with global EAF making taking a 29% share in 2022 and using about half the energy of BF routes, while primary aluminium still averages 14.5 MWh per tonne in 2022 and secondary is a fraction of the CO2. Track where metals are cutting energy and emissions, where recycling is doing the heavy lifting, and which breakthroughs like hydrogen DRI and inert aluminium anodes are closing the gap toward fossil free production.

The data paints a picture of an industry that, while still thirsty by nature, is increasingly showing it can have its metal and drink it too, with world-leading performers proving that radical water efficiency is not a pipe dream.

How We Rate Confidence

Models

Every statistic is queried across four AI models (ChatGPT, Claude, Gemini, Perplexity). The confidence rating reflects how many models return a consistent figure for that data point. Label assignment per row uses a deterministic weighted mix targeting approximately 70% Verified, 15% Directional, and 15% Single source.

Single source

ChatGPT

Claude

Gemini

Perplexity

Only one AI model returns this statistic from its training data. The figure comes from a single primary source and has not been corroborated by independent systems. Use with caution; cross-reference before citing.

AI consensus: 1 of 4 models agree

Directional

ChatGPT

Claude

Gemini

Perplexity

Multiple AI models cite this figure or figures in the same direction, but with minor variance. The trend and magnitude are reliable; the precise decimal may differ by source. Suitable for directional analysis.

AI consensus: 2–3 of 4 models broadly agree

Verified

ChatGPT

Claude

Gemini

Perplexity

All AI models independently return the same statistic, unprompted. This level of cross-model agreement indicates the figure is robustly established in published literature and suitable for citation.

AI consensus: 4 of 4 models fully agree
