Siemens

Siemens, headquartered in Germany and operating in the Automatic Environmental Control Manufacturing for Residential, Commercial, and Appliance Use industry, has set ambitious climate commitments.

In 2025, Siemens reported a total of approximately 159.5 billion kg CO2e. This breaks down into approximately 288 million kg CO2e for Scope 1 emissions, approximately 71 million kg CO2e for Scope 2 (market-based), and a substantial 159.1 billion kg CO2e for Scope 3 emissions. The largest contributor to Scope 3 emissions was the use of sold products, accounting for approximately 134.1 billion kg CO2e.

Prior to this, in 2024, Siemens recorded approximately 441 million kg CO2e for Scope 1 and 2 emissions (market-based) and approximately 416.8 billion kg CO2e for Scope 3 emissions. In 2023, the company reported approximately 550 million kg CO2e for Scope 1 and 2 (market-based) and approximately 489 billion kg CO2e for Scope 3. In 2022, Scope 1 and 2 emissions were approximately 582 million kg CO2e (market-based), with Scope 3 emissions at approximately 457.6 billion kg CO2e.

Siemens has committed to significant emissions reductions:

• Near-term targets:
  • A 55% reduction in Scope 1 and 2 emissions for Siemens (excluding SHS) by 2025, compared to 2019 levels.
  • A 90% reduction in Scope 1 and 2 emissions by 2030, compared to 2019 levels.
  • A 30% reduction in Scope 3 emissions by 2030, compared to 2019 levels.
• Long-term targets:
  • Achieve net-zero greenhouse gas emissions across the value chain by 2050.
  • Reduce supply chain emissions by 20% by 2030 and eliminate them completely by 2050.
  • The company also aims for its production facilities and buildings worldwide to achieve a net-zero carbon footprint by 2030.

Siemens is a signatory to the Climate Pledge, demonstrating its commitment to a net-zero future. The company's reduction targets are verified by the Science Based Targets initiative (SBTi), which aligns with a 1.5°C warming pathway.
