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.
Lockheed Martin scores 27/100 (Significant gaps) on SINK's independent climate assessment, scored from public data only. Fees pay for the review, never the result. Last verified May 2026.
That places Lockheed Martin joint 683rd of 847 companies scored, and 4th of 4 in Defence.
