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. Scores are free. Nobody can pay to change a score, speed it up or hide it. Last verified October 2026.
That places RTX joint 783rd of 1,023 companies scored, and 3rd of 4 in Defence.
What is RTX doing well, and where does it fall short?
Strongest on Carbon Footprint: Operations and Carbon Footprint: Supply Chain (8/10, 6/10). Weakest on Nature & Biodiversity Impact and Emissions Trajectory (1/10, 3/10).
