Siemens Energy

Does the core business genuinely avoid or reduce emissions, or build climate resilience? Share of revenue that is actually 'green'. Fossil-dependent models score low.

Grid Technologies and Siemens Gamesa are genuine climate enablers — essential to renewables integration — but Gas Services remains a large and fast-growing segment, with 194 gas turbines sold in FY2025 (nearly double FY2024), limiting the net impact score significantly.

Credible, science-based targets (SBTi), a real net-zero plan with progress to date, and CDP disclosure — not just a dated press release.

SBTi validated Siemens Energy's 2030 and 2050 emission reduction targets in line with the net-zero standard; the company reports a 55% reduction in operational emissions vs. 2019 and a Scope 3 downstream reduction target of 28% by 2030, with CDP Climate Change A-list status — credible but the Scope 3 upstream and gas-services pathway remains a material gap.

Operational footprint, labour and social practices, and governance quality across the company's own operations and supply chain.

Sustainalytics ESG Risk Rating of 14.2 (low risk, top industry list 2025), EcoVadis 97th-percentile score, 3% adjusted gender pay gap, and GRI-aligned reporting reflect solid operational ESG practices, though the SF6 transition in grid products and ongoing Siemens Gamesa quality issues temper the score.

Quality of disclosure, independent third-party verification, and how much hard data backs the company's claims.

Siemens Energy publishes a standalone GRI-aligned Sustainability Report with third-party limited-assurance on key ESG KPIs, CDP A-list disclosure, and has collected Scope 3 downstream data for ~90% of emissions — strong by industry standards, though assurance is 'limited' not 'reasonable' and Scope 3 upstream completeness is still partial.

Controversies, litigation, pollution, fossil-fuel lobbying, conflict-zone involvement and governance scandals. Higher means cleaner.

NGOs including Urgewald, Beyond Fossil Fuels, Greenpeace Germany, and Friends of the Earth publicly accused Siemens Energy at its 2026 AGM of greenwashing — citing growing fossil gas revenues and fossil lobbying as contradicting its energy-transition branding; earlier controversies include gas plant involvement in conflict-adjacent geographies and coal plant supply at spin-off.
