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. Scores are free. Companies can never pay for anything about their own score. Last verified May 2026.
That places Lockheed Martin joint 759th of 934 companies scored, and 4th of 4 in Defence.
What is Lockheed Martin doing well, and where does it fall short?
Strongest on Carbon Footprint: Operations and Transparency & Accountability (7/10, 6/10). Weakest on Nature & Biodiversity Impact and Controversies & Red Flags (3/10, 3/10).
Where Lockheed Martin lost points
For each question that lost points, the evidence our public rubric looks for that we didn't find.
- Emissions from its own operations7/10Its own emissions aren't independently verified or tracked over several years.
- Emissions from its supply chain4/10Most of its supply-chain (Scope 3) emissions aren't measured.
- Whether its emissions are falling5/10No evidence of a year-on-year fall in its total emissions.
- How clean its energy is4/10Less than half its energy shown to be renewable, or no transition plan.
- Its effect on nature3/10No assessment of its effect on nature, and no basic environmental policy.
- How it uses materials and handles waste4/10No measurable waste or recycling targets reported publicly.
- Its effect on water4/10No measured water footprint with reduction targets.
- Its climate targets4/10Its targets aren't science-based or committed to the Science Based Targets initiative.
- How openly it reports6/10No annual impact report, or no pay linked to climate targets.
- Its record on controversies3/10Points deducted for controversies or its business model. The finding is under question 10.

Who scores higher in Defence?
The 3 companies in the sector scoring nearest above Lockheed Martin.
Babcock has validated science-based targets and publishes comprehensive Scope 1&2 data, but Scope 3 emissions—97% of its footprint—rose 29.7% since 2021.
See the breakdown →BAE Systems reports operational emissions reductions but Scope 1 rose year-on-year, and Scope 3, the bulk of its footprint, is only estimated from revenue.
See the breakdown →RTX's Scope 1 and 2 emissions are 27% below 2019, but its Scope 3, about 95% of its footprint, has not fallen, and the use-phase emissions of its engines rose in the latest data.
