alstom's reported carbon emissions
Alstom, a leading company in railway transportation services headquartered in France, has made significant commitments to reducing its carbon emissions.
Emissions Overview:
- 2025: Alstom reported a total of approximately 48.7 billion kg CO2e. This breaks down into roughly 87.3 million kg CO2e for Scope 1 emissions, and approximately 40.6 million kg CO2e for Scope 2 (market-based). Scope 3 emissions were substantial, driven largely by the use of sold products (about 41.5 billion kg CO2e) and purchased goods and services (about 6.6 billion kg CO2e).
- 2024: Total emissions for 2024 were approximately 45.0 billion kg CO2e. Scope 1 emissions were around 86.7 million kg CO2e, with Scope 2 (market-based) at approximately 50.4 million kg CO2e. The use of sold products was the largest contributor to Scope 3 emissions, at about 37.3 billion kg CO2e.
- 2023: Alstom's total emissions were approximately 48.3 billion kg CO2e (calculated from provided scope data). Scope 1 emissions were around 94.0 million kg CO2e, and Scope 2 emissions were approximately 85.0 million kg CO2e. Scope 3 emissions were dominated by the use of sold products, at around 29.0 billion kg CO2e, and purchased goods and services at approximately 6.5 billion kg CO2e.
- 2022: Scope 1 and 2 emissions combined were approximately 230.0 million kg CO2e.
- 2021: Scope 1 and 2 emissions combined were approximately 99.0 million kg CO2e. Scope 3 emissions from the use of sold products were substantial, at about 21.0 billion kg CO2e, alongside business travel of approximately 5.0 million kg CO2e.
- 2020: Scope 1 and 2 emissions combined were approximately 124.0 million kg CO2e.
- 2016: Total emissions were around 113.0 million kg CO2e, with Scope 2 emissions at approximately 62.0 million kg CO2e.
- 2015: Total emissions were approximately 124.0 million kg CO2e, with Scope 1 emissions at about 54.0 million kg CO2e and Scope 2 at approximately 69.0 million kg CO2e.
- 2014: Total emissions were approximately 124.0 million kg CO2e, comprising about 53.0 million kg CO2e for Scope 1 and 70.0 million kg CO2e for Scope 2.
Climate Commitments and Reduction Targets:
Alstom is committed to ambitious climate goals, including:
- Net Zero by 2050: The company aims to achieve Net Zero carbon emissions across its entire value chain by 2050. This long-term ambition includes contributing to the decarbonisation of the transport sector.
- Scope 1 & 2 Emissions Reduction: Alstom has a near-term target to reduce absolute Scope 1 and 2 GHG emissions by 40% by FY2030 from a FY2021 baseline. This target is validated by the Science Based Targets initiative (SBTi) and is aligned with a 1.5°C scenario.
- Scope 3 Emissions Reduction:
- Intensity of Scope 3 emissions from purchased goods and services is targeted for a 30% reduction by 2030/31 from a 2022/23 baseline.
- Intensity of Scope 3 emissions from passenger transport solutions is targeted for a 42% reduction per passenger-kilometre and a 35% reduction per tonne-kilometre by 2030/31 from a 2021/22 baseline. This target is also validated by SBTi and aligned with a well-below 2°C pathway.
- Earlier targets included a 25% reduction in absolute Scope 1 and 2 emissions by 2025 from a 2019 base year, and a 35% reduction in Scope 3 emissions from the use of sold products (rolling stock) per passenger-km and per tonne-km by 2030 from a 2019 base year.
Alstom's commitments demonstrate a comprehensive strategy to address its carbon footprint across its operations and value chain, aligning with global climate objectives.
