Rio Tinto scores 3 points higher than Glencore plc on SINK.
Rio Tinto is more sustainable according to SINK's scores, scoring 23/100 vs Glencore plc's 20/100, a difference of 3 points.
Glencore plc scores 20/100 on SINK (Significant gaps). Glencore reports 18.7 Mt operational emissions and 381 Mt Scope 3, but excludes acquired coal mines from trajectory claims and omits traded commodity Scope 3 entirely. Renewable energy covers 11% of use. Active climate policy opposition, 16 water fines in 2025, and plans to expand coal by 30% despite 'phase-down' rhetoric undermine stated targets.
Rio Tinto scores 23/100 on SINK (Significant gaps). Rio Tinto reports comprehensive climate data but its equity-basis emissions rose year on year. Its Scope 1 and 2 cuts rely partly on unbundled renewable certificates; it lacks an overall Scope 3 reduction goal and faces multiple regulatory convictions for water and effluent violations.
Both companies are rated on the same 10-question SINK rubric: Scope 1/2/3 carbon footprint, energy source, nature and biodiversity, resource use, water, emissions trajectory, science-based targets, transparency, and controversies. Scores are 0–100, based on public data, and fully reproducible.
