Siemens Energy operates with solid operational emissions disclosure and 100% renewable electricity, but rising absolute emissions across all scopes in FY2024 reverse multi-year progress. Scope 3 coverage remains fragmented, and the company actively lobbies to preserve fossil gas in energy policy despite climate commitments.
Siemens Energy scores 31/100 (Below expectations) 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 Siemens Energy joint 658th of 934 companies scored, and 10th of 12 in Electrical Equipment / Lighting.
What is Siemens Energy doing well, and where does it fall short?
Strongest on Energy Source and Carbon Footprint: Operations (8/10, 7/10). Weakest on Emissions Trajectory and Carbon Footprint: Supply Chain (3/10, 4/10).

Who scores higher in Electrical Equipment / Lighting?
The 3 companies in the sector scoring nearest above Siemens Energy.
Siemens has cut its own emissions 62% since 2019, but 84% of its 159.5 MtCO2e footprint is the modelled lifetime electricity use of the products it sells, and none of its supply-chain figures use measured data.
See the breakdown →Honeywell publishes sustainability reports but hides absolute emissions figures behind intensity metrics, masking whether actual pollution is declining.
See the breakdown →ABB's own emissions are 79% below 2019, but its total footprint rose 8% in 2025 to 425 MtCO2e, 97% of it the modelled lifetime energy use and losses of the products it sells.
