alstom's reported carbon emissions
Alstom, a leader in railway transportation services headquartered in France, is committed to ambitious climate targets, including achieving Net Zero carbon emissions across its value chain by 2050. The company has set near-term goals to reduce its direct and indirect greenhouse gas (GHG) emissions from its sites by 40% by 2030, using a 2021/22 baseline. This target is validated by the Science Based Targets initiative (SBTi) and aligns with a 1.5°C scenario. In terms of recent emissions data, for the reporting year 2025, Alstom reported a total of approximately 48.7 billion kg CO2e. This figure breaks down into approximately 87.3 million kg CO2e for Scope 1 emissions and about 40.6 million kg CO2e for Scope 2 (market-based). Scope 3 emissions were significant, primarily driven by the use of sold products, accounting for approximately 41.5 billion kg CO2e. For the reporting year 2024, Alstom's total emissions were approximately 45.0 billion kg CO2e. Scope 1 emissions were around 86.7 million kg CO2e, and Scope 2 emissions (market-based) were approximately 50.4 million kg CO2e. Scope 3 emissions in this year were largely dominated by the use of sold products, totalling approximately 37.3 billion kg CO2e. In the reporting year 2023, Alstom's total emissions amounted to approximately 43.8 billion kg CO2e, with Scope 1 emissions at approximately 94 million kg CO2e and Scope 2 emissions at about 85 million kg CO2e. The use of sold products was again the largest contributor to Scope 3 emissions, at approximately 29 billion kg CO2e. Alstom is also focused on reducing the intensity of its Scope 3 emissions, aiming for a 30% reduction in emissions from purchased goods and services per euro of added value by 2030/31. Furthermore, the company aims to reduce the intensity of Scope 3 emissions from passenger transport solutions by 42% per passenger-kilometre and 35% per tonne-kilometre by the same timeframe, also validated by SBTi and aligned with a well-below 2°C pathway.
