Environmental footprint

Towards cleaner operations

As a key player in the mobility sector, Alstom is at the forefront of the challenges facing society today, from global warming to rapid urbanisation. Understanding the importance of reducing the environmental impact of its operations, the Company strives to make more sustainable choices at every step, from energy sources to transportation and recycling.

Climate change is changing weather patterns and disrupting balance of nature. To help to tackle climate risks, Alstom assessed in 2022 the climate resilience of its assets based on scenarios consistent with the IPCC (scenario SSP5 8.5 and scenario SSP2 4.5 scenario). The Group also carried out this year an initial impacts analysis of its sites on Biodiversity with the help of an expert firm. Next years, will be dedicated to pursue these initiatives and further deploy adaptation plan and biodiversity actions.

As a signatory member of the United Nations Global Compact, Alstom supports the Sustainable Development Goals (SDGs) that aim to end extreme poverty, protect the planet and ensure prosperity for all by 2030. Alstom bases its value system and business approach on the 10 principles of the Global Compact and submits its Communication of Progress (COP) each year. Alstom’s Sustainability and CSR policy ensures that the Company’s daily activities, core business and initiatives contribute to delivering on its core mission of supporting the transition to sustainable mobility systems. Alstom believes this transition has particular relevance for three SDGs:

Industry, innovation and infrastructure (SDG 9);
Sustainable cities and communities (SDG 11); and
Climate action (SDG 13).

Most specifically, Alstom strongly contributes to Target 11.2 to provide access to safe, affordable, accessible and sustainable transport systems for all, notably by expanding public transport.

A strong ESG roadmap supported by clear targets

The Group's ambition is to be net-zero emission by 2050, while contributing to increase low carbon mobility for the transport sector.

In July 2023, Alstom's emissions reduction targets have been approved by the Science Based Targets initiative (SBTi):
- 40% reduction of absolute scope 1 & 2 GHG emissions by 2030*
- 42% reduction per passenger-km of scope 3 GHG emissions from the use of sold products covering passenger rolling stock by FY2029/30*
- 35% reduction per ton-km of scope 3 GHG emissions from the use of sold products covering freight by FY2029/30*
  
  *Baseline: 2021/22
Alstom's net-zero ambition means that climate targets will be gradually expanded to cover the whole value chain, by setting the right measure efforts and establishing the milestones towards absolute CO2 reduction by 2050. Alstom is committed to reduce the intensity of GHG emissions (scope 3) from purchased goods and services and of its transportation & distribution by 30% by 2029/30 from a 2022/23 baseline.

Saving water, recovering waste and using renewable energy

VOC are the main air pollutants emitted by Alstom operations. In 2025, the VOC emissions amounted to 328 tons. By implementing paint substitution initiatives (e.g. replacement of solvent-containing paints by aqueous paints), Alstom has significantly reduced its VOC emisisions since 2010. The Company continues to pay particular attention to these emissions. In 2024, a new roadmap is realigned and covers: new paint booth, greater emphasis on solvent-free paints and high solid content paints and investigation of other application systems such as electrostatic robots and guns under nitrogen.
Since 2017, Alstom decided to monitor water intensity on top of water gross consumption. This monitoring is more relevant, as it is defined by the volume of water consumed related to its activity, which is measured in hours worked. At the end of 2025, water intensity is 9.9liters/hours worked.
At the end of 2025, the recovery rate is at 93%, wth the 2026 target set at 93%.

The recycling rate for 2025 is 81%, with the target set at 85% in 2030.
In addition to controlling the energy emission of its operations, the Group has taken additional steps committing to use 100% of its electricity from renewable sources by 2025. The group achieved this target of 100% of electricity supplies from renewable origin.

Clean operations certification

All the sites have maintained their ISO 14001 certification in 2025/26. 84% of Alstom employees work on certified sites or projects, the target being to have 100% of Alstom employees on certified sites.

By signing a Virtual Power Purchase Agreement (VPPA) in July 2023, in order to secure the procurement of green power certificates for 10 years, Alstom achieved an important milestone to accelerate decarbonisation related to energy consumption of its facilities and sites in Europe. The power will be purchased as produced from a Spanish solar asset, for an estimated volume of 160 GWh/year. The solar farm is expected to start operating early 2025 and is deemed to cover 80% of Alstom’s electricity consumption in Europe.
