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 emissions are rising in absolute terms while it hides behind intensity targets and incomplete Scope 3 reporting. The company faces a $9.5B unpaid judgment for Ecuador contamination, active FTC greenwashing complaints, and ranks among the world's most obstructive forces on climate policy. No credible net-zero pathway exists.
Saudi Aramco scores 12/100 on the SINK sustainability index (Critical concern). Saudi Aramco is the world's largest corporate emitter, refusing to disclose ~96% of its emissions (Scope 3: 1.6–1.84 billion tonnes CO₂e annually) while pursuing intensity-only targets that explicitly allow absolute emissions to rise. Active lobbying against climate policy, greenwashing complaints, and UN human rights warnings mark a company prioritising shareholder returns over climate responsibility.
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.
