Siemens

Siemens, headquartered in Germany, operates in Automatic Environmental Control Manufacturing.

In 2025, Siemens' estimated total carbon emissions are approximately 159.5 billion kg CO2e. This includes about 1.4 million kg CO2e from Scope 1 emissions, 707 million kg CO2e from market-based Scope 2 emissions, and approximately 179.2 billion kg CO2e from Scope 3 emissions. Key contributors to Scope 3 emissions include the use of sold products (about 134.1 billion kg CO2e) and purchased goods and services (about 9.4 billion kg CO2e).

Looking back, Siemens' estimated total emissions were approximately 425.7 billion kg CO2e in 2024, approximately 489.5 billion kg CO2e in 2023, about 458.2 billion kg CO2e in 2022, and around 482.7 billion kg CO2e in 2021.

Siemens is committed to significant climate action with several reduction targets. The company aims for net-zero greenhouse gas emissions across its value chain by FY2050, as validated by the Science Based Targets initiative (SBTi) with a 1.5°C classification.

Near-term SBTi targets include:

• A 90% reduction in absolute Scope 1 and 2 GHG emissions by FY2030 from a FY2019 base year.
• A 30% reduction in absolute Scope 3 GHG emissions by FY2030 from a FY2019 base year.

Long-term SBTi targets include:

• Maintaining a minimum of 90% absolute Scope 1 and 2 GHG emissions reductions from FY2030 through FY2050 from a FY2019 base year.
• A 90% reduction in absolute Scope 3 GHG emissions by FY2050 from a FY2019 base year.

Additional commitments include:

• Reducing emissions from business operations (Scopes 1 and 2, excluding Siemens Healthineers or SHS) by 55% by 2025 compared to 2019.
• Further reducing emissions from business operations (Scopes 1 and 2, excluding SHS) by 90% by 2030 compared to 2019.
• Achieving net-zero operations by 2030.
• Reducing supply chain emissions (Scope 3) by 20% by 2030, with a long-term goal of net-zero in the supply chain by 2050.
• Siemens has signed The Climate Pledge, committing to achieve net-zero carbon emissions by 2040.
