alstom

Alstom, a French railway transportation services company, reported total carbon emissions of approximately 48.7 billion kg CO2e in 2025. This figure comprises about 87.3 million kg CO2e from Scope 1 emissions, 40.6 million kg CO2e from market-based Scope 2 emissions, and approximately 48.6 billion kg CO2e from Scope 3 emissions. A significant portion of the Scope 3 emissions, about 41.5 billion kg CO2e, was attributed to the use of sold products. Other notable Scope 3 categories included purchased goods and services at approximately 6.6 billion kg CO2e, and end-of-life treatment of sold products at around 137.4 million kg CO2e.

Looking back, Alstom's total carbon emissions in 2024 were approximately 45.0 billion kg CO2e, with Scope 1 emissions at about 86.7 million kg CO2e, market-based Scope 2 emissions at roughly 50.4 million kg CO2e, and Scope 3 emissions accounting for the majority, around 44.8 billion kg CO2e.

Alstom has set ambitious climate commitments. The company is committed to achieving Net Zero carbon across its value chain by 2050. Near-term targets, validated by the Science Based Targets initiative (SBTi) and aligned with a 1.5°C scenario, include a 40% absolute reduction in Scope 1 and Scope 2 GHG emissions from its sites by 2030, using a 2021/22 baseline. Additionally, Alstom aims to reduce the intensity of Scope 3 emissions from purchased goods and services by 30% by 2030/31 from a 2022/23 baseline. For downstream Scope 3 emissions, Alstom targets a 42% reduction in intensity per passenger-km for passenger transport solutions and a 35% reduction per ton-km for freight solutions by 2030/31, against a 2021/22 baseline, aligned with a well-below 2°C pathway.
