Porsche reports comprehensively on production emissions and renewable energy, but relies heavily on per-vehicle intensity metrics that mask flat or worsening absolute reductions. SBTi targets remain unvalidated. A 2022 settlement for emissions cheating on 500,000 vehicles and ongoing weak lobbying on climate policy undermine credibility.
Porsche scores 31/100 (Below expectations) 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 Porsche joint 658th of 934 companies scored, and joint 9th of 26 in Automotive.
What is Porsche doing well, and where does it fall short?
Strongest on Transparency & Accountability and Carbon Footprint: Operations (7/10, 6/10). Weakest on Nature & Biodiversity Impact and Controversies & Red Flags (3/10, 3/10).
