Our verdict

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.

Kia scores 28/100 (Significant gaps) on SINK's independent climate assessment, scored from public data only. Scores are free. Companies can never pay for anything about their own score. Last verified May 2026.

That places Kia joint 731st of 934 companies scored, and joint 14th of 26 in Automotive.

The ten questions

What is Kia doing well, and where does it fall short?

Strongest on Carbon Footprint: Operations and Transparency & Accountability (7/10, 7/10). Weakest on Emissions Trajectory and Energy Source (4/10, 4/10).
