Alstom recognised for its sustainability achievements with major environmental distinctions
Alstom recognised for its sustainability achievements with major environmental distinctions
-
Earned top grade of A for 2024 by the CDP for best practices in climate risk management
-
Achieved Top 10 ranking of #7 in Corporate Knights 2025 list of 100 Most Sustainable Companies and #4 in inaugural Europe 50 list
Alstom's CSR priorities are integral to the company's strategy, a plan that reflects our overall Green ambition: to lead the charge to more sustainable transport systems worldwide while acting as a responsible and ethical corporate citizen.
As testimony of our vision turned into action, Alstom has been given two outstanding distinctions. First, we have earned the CDP’s maximum grade of A for Climate for 2024. Not to be outdone, we’ve climbed in Corporate Knights’ annual ranking of the 100 most sustainable companies in the world to #7 as well as #4 in the inaugural Europe 50 list. These underscore the company’s ambitious sustainability roadmap and bold climate objectives.
While we are proud of this recognition, Alstom is pushing forward, strengthening our commitments to sustainable development levers such as the circular economy.
How far are we on our sustainability journey?
Alstom's CSR priorities have three main climate-focused destinations:
- Move towards net zero mobility
- Enable resource preservation
- Drive a responsible supply chain
The company has committed to reducing 40% of its 2021/22 operational CO2 emissions by 2030. Additionally, by 2030/31, we are working to reduce the intensity of greenhouse gas emissions by 42% per passenger-kilometre and by 35% per ton-kilometre.
How are we doing this?
To reduce our operational CO2 emissions specifically, we’re installing equipment photovoltaic panels on roofs or available land of our manufacturing facilities to generate renewable energy. We’ve also entered power purchase agreements, focused on solar development providing the largest part of renewable energy we use. Altogether, we are aiming at 100% electricity from renewable sources. We’re recycling waste from operations at all sites by installing collectors in our facilities’ workshops, separating materials such as cardboard, wood boxes and aluminum scraps. And we’re spearheading circular economy initiatives with our suppliers and customers, for example by changing only required components through predictive maintenance or parts reuse.
We galvanize all metiers worldwide network of CSR and Sustainability champions, EHS, Eco-design, Sustainable Procurement who roll out actions plans, develop best practices and contribute to the reporting of results and achievements. For example, recently in Mexico, our Sahagún plant has boosted the installation of photovoltaic panels. In addition, Alstom Spain obtained AFNOR ISO 26000 certification for fully integrating the principles of sustainability and good governance in its model.
We have built eco-design and circularity into our DNA for a number of years. We are:
-
Innovating solutions to reduce material intensity through condition-based maintenance, avoiding the changing of parts that are still in good and safe condition
-
Reusing parts and components to give them a second life by making them available through our StationOne online market place
-
95%Our trains are already 95% recyclable
-
25%Some of our trains, such as the Metropolis metro trains or Avelia Horizon high-speed trains, already contain more than 25% recycled content, with an eye towards 40% by 2030
-
30%Alstom's sustainable purchasing strategy calls for sourcing recycled materials as a huge lever reducing the carbon emissions of goods and services purchased by 30% by 2030
Ratings agencies are noticing
Alstom's performance is regularly evaluated by prominent non-financial ESG organizations, ensuring transparent and consistent reporting to stakeholders. This also enables us to benchmark ourselves against industry peers and influential sustainability leaders.
Since March 2025, we’ve received:
- CDP maximum A score for Climate for 2024: A testament to our relentless pursuit of environmental excellence, we’ve built on our A- score in 2023. Every year, Alstom undergoes a rigorous evaluation process, submitting comprehensive responses to a detailed questionnaire covering five pillars:
- Climate
- Water
- Forest
- Pollution
- Biodiversity
- Ranking of 7 in Corporate Knights’ 100 Most Sustainable Companies of 2025: Alstom’s Top Ten finish is strong progress from last year’s position of 19.
- Ranking 4 of 50 in Corporate Knight's inaugural Europe 50 list
These prestigious recognitions position the company as one of just a handful of global sustainability leaders.
"These positive recognitions are proof of our dedication to sustainability. Despite the increasingly rigourous evaluation criteria, we’re improving each year. We’re proud and determined to continue setting new benchmarks in sustainability."
And what about the rest of the journey? What lies ahead? For the decarbonisation of mobility, we believe circularity is key.
Our customers now require very high levels of recycled content. We are working with all our partners to accelerate the deployment of circular economy best practices throughout the value chain. For example, by:
- increasing the use of bio-sourced, recycled and renewable materials
- specifying material requirements to suppliers
- co-developing of new materials that meet these specifications
Alstom also relies on data to deploy its circular economy roadmap - but data is only meaningful if it’s shared at the right level throughout the value chain.
We’re an active member of organisations that will use data for the traceability of materials and components. Alstom adheres to GS1 standards along with other rail industry players. The GS1 initiative intends to systematise the use of harmonised labels with a unique identification number for each traceable part. This standard provides digital continuity throughout the life cycle of a part, product or fleet.
By sharing and analysing this data, it’s possible to optimize predictive maintenance, modernization and repairs. This ensures savings in time and resources, reliability and optimum service life, all while limiting environmental impact by reducing maintenance to the strictly necessary.
On the supply side, Alstom's sustainable purchasing strategy calls for sourcing recycled materials as a huge lever reducing the carbon emissions of goods and services purchased by 30% by 2030.
An example from last September: Alstom and steelmaker SSAB partnered to supply steel containing more than 95 % recycled steel and manufactured with near-zero carbon dioxide (CO2) emissions for a new locomotive platform. The Swedish manufacturer is one of Alstom’s most advanced suppliers in terms of circular economy best practices.
In fact, we’ll be showcasing our sustainability ambitions and innovations at the upcoming UITP 2025 Summit, one of the world’s foremost public transportation events:
- The Alstom booth will feature a Decarbonise Life Cycle exhibit, offering an immersive and interactive digital experience that will demonstrate Alstom’s sustainability leadership across its rolling stock portfolio and vehicle maintenance
- On Monday, June 16, Véronique Andriès, VP Sustainability and CSR, will give a talk: Adapting Procurement Practices for a More Sustainable Public Transport Supply Chain
With the widest geographical reach and most comprehensive portfolio in the rail industry, Alstom is in a unique position to answer the global call for sustainable mobility. Our recent recognitions are proof that our environmental roadmap is on target, and we’re confident that we’re heading in the right direction to tackle the circular economy.
