Rio Tinto reports comprehensive operational emissions data but remains the highest Scope 1 & 2 emitter among mining peers globally. The company has no Scope 3 reduction target despite Scope 3 representing 95% of emissions and rising since 2020. Active anti-climate lobbying contradicts public commitments; the Juukan Gorge destruction and multiple regulatory violations expose systemic environmental and cultural harm.
