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. Its 46% cut by 2030 covers operations only, with no value-chain goal. It paid water-discharge penalties in 2025, including $458,211 in Colorado, and LobbyMap grades it D+ for trade-group ties and support for cutting Inflation Reduction Act climate incentives.
RTX scores 28/100 (Significant gaps) on SINK's independent climate assessment, scored from public data only. Fees pay for the review, never the result. Last verified October 2026.
That places RTX joint 658th of 847 companies scored, and 3rd of 4 in Defence.
Where RTX sits among defence peers.
Among the 4 major defence brands we've scored, RTX sits 3rd of 4.
Its three lowest-scoring questions, and what the evidence didn't show.
No biodiversity policy, nature-risk assessment, TNFD statement, deforestation commitment or quantified nature footprint identified in cited sources.
Scope 3 is flat to rising: Category 11 use-phase emissions grew from 8.5M t to 13.6M t. The dominant scope is not decarbonizing, offsetting operational gains.
The full reasoning is in the ten questions below.
