Lockheed Martin scores 27/100 (Significant gaps) on SINK's independent climate assessment — scored from public data only, no company payment can change a number. Last verified May 2026.
That places Lockheed Martin joint 650th of 809 companies scored, and 3rd of 3 in Defence.
Lockheed Martin operates with comprehensive operational emissions reporting (Scope 1+2 verified, on track to 2030 target) but masks massive supply chain emissions through spend-based estimation rather than primary data. Legacy contamination at multiple sites and active obstruction of climate policy through trade associations disqualify any credibility claim.
