Why it's on ClimateTicker

Siemens Gamesa is a structurally legitimate climate company: its entire revenue base comes from manufacturing wind turbines that displace fossil-fuel electricity generation, enabling customers to avoid an estimated 356 million tonnes of CO2 per year. However, a catastrophic 2023 quality crisis — faulty components across 15–30% of its onshore fleet, a €4.5 billion loss, and a German government bailout — revealed serious governance failures and raises questions about whether its products actually deliver contracted clean-energy output at scale. Investors should treat it as a genuine mitigation asset with real execution and integrity risk, not a greenwasher.

mitigationSiemens Gamesa earns revenue by designing, manufacturing, and selling onshore and offshore wind turbines (primarily the SG 14-236 DD platform for offshore) and through long-term service and maintenance contracts on its installed base, now operated as a wholly owned subsidiary of Siemens Energy.

lowScope 3 emissions trajectory missed in FY2024

Despite SBTi-validated supply-chain emission reduction targets, Siemens Energy's FY2024 sustainability report disclosed that Scope 3 emissions increased versus FY2023 due to higher order intake, putting the company off its SBTi trajectory.source ↗

The German government provided approximately €7.5 billion in guarantees after Siemens Energy lost bank and investor support due to the Gamesa quality crisis, with the Siemens Energy CEO stating 'too much had been swept under the carpet' at Siemens Gamesa.source ↗

A systemic failure in rotor blades and bearings affecting 15–30% of the 4.X and 5.X onshore fleet was concealed or under-reported internally; the CEO admitted the company 'sold wind turbines that were not sufficiently tested', triggering €4.5 billion in losses and a €7.5 billion German government bailout.source ↗
