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. Fees pay for the review, never the result. Last verified May 2026.
That places Siemens Energy joint 588th of 847 companies scored, and 8th of 10 in Electrical Equipment / Lighting.

The 3 companies in the sector scoring nearest above Siemens Energy.
Siemens has delivered genuine operational emissions cuts (60% since 2019) and secured SBTi validation, but faces a critical credibility gap: it funded the Carmichael coal mine in 2020 despite global activist pressure, and holds undisclosed trade association memberships misaligned with climate.
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 has cut operational emissions 78% since 2019 and validated SBTi net-zero targets, but relies heavily on unbundled renewable energy certificates with limited additionality.
