Both companies are tied at 12/100 on SINK's sustainability index.
Chevron scores 12/100 on the SINK sustainability index (Critical concern). Chevron's sustainability record is defined by rising absolute emissions, intensity-only targets that allow production growth to outpace efficiency gains, and systematic obstruction of climate policy. The company reports Scope 1 & 2 emissions with third-party verification but covers only 1 of 15 Scope 3 categories. An unresolved $9.5B judgment for 16 billion gallons of Amazon contamination, FTC greenwashing complaints, and InfluenceMap's ranking as the most obstructive oil company on climate policy expose fundamental misalignment between stated commitments and corporate action.
Saudi Aramco scores 12/100 on the SINK sustainability index (Critical concern). Saudi Aramco is the world's largest corporate emitter, refusing to disclose Scope 3 emissions (~1.6–1.84 Gt CO₂e annually, 4.4% of global emissions). Operational emissions are rising, targets are intensity-only while production expands, and the company actively lobbies against climate action. Scope 3 non-disclosure alone is disqualifying.
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.
