Kia scores 5 points higher than Hyundai Motor Company on SINK's sustainability index.
Kia is more sustainable according to SINK's open sustainability index, scoring 28/100 vs Hyundai Motor Company's 23/100 — a difference of 5 points.
Hyundai Motor Company scores 23/100 on the SINK sustainability index (Significant gaps). Hyundai reports operational emissions transparently but absolute global emissions rose 6% in 2023, driven by use-phase Scope 3 that dominates the footprint. The company lacks SBTi-validated targets, sources coal-powered aluminum from Indonesia, and faces documented greenwashing criticism for LNG expansion after RE100 pledges. Supply chain accountability and emissions trajectory remain the weakest areas.
Kia scores 28/100 on the SINK sustainability index (Significant gaps). Kia discloses comprehensively but emissions trajectory is broken: Scope 1+2 improved 17%, but Scope 3 dominates at 99% of total and grows with record sales. Net-zero 2045 relies on offsets. A decade-old EPA emissions fraud settlement and obstructive trade association lobbying undercut credibility.
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.
