Same metric. Same year.
Different rulebook.

Mining publishes more ESG data than ever — and nearly half of head-to-head comparisons between miners aren’t like-for-like. Kestrel reads every sustainability report, factbook, and annual report, standardises every number to one canonical metric standard, and flags what quietly changes: restated figures, redrawn boundaries, dropped targets. Every figure traceable to the exact cell, page, or paragraph it came from.
