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.
