Hyundai Motor Company scores 23/100 on the SINK sustainability index (Significant gaps). Hyundai's sustainability record is dominated by rising absolute emissions, unvalidated net-zero claims, and greenwashing. Absolute emissions grew 6% in 2023. BEV sales remain single-digit. The company lacks SBTi validation, sources coal-powered aluminum, and faces documented criticism from Greenpeace and InfluenceMap for climate obstruction and misalignment between pledges and action.
Kia scores 28/100 on the SINK sustainability index (Significant gaps). Kia publishes comprehensive sustainability data with third-party verification and SBTi near-term targets, but absolute emissions are rising with record sales. Scope 3 dominates at 99% of total emissions yet remains driven by vehicle use-phase and growing volumes. The company has resolved a major EPA emissions fraud settlement but continues obstructive climate lobbying through trade associations.
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.
