The booming demand for urban mobility is leading to a significant increase of all transport modes. As a consequence, the risk of a further growing pollution and subsequent increase in environmental and health challenges has never been higher. 

Curbing worldwide emissions from transport will be key in reducing our collective environmental footprint. 

That's why we are fully committed to reducing the carbon footprint of transport solutions, as well as to adopting climate-resilient and low-carbon strategies that will enable the transition to a truly sustainable global transport system. 

Our pledge for carbon neutrality in transport 

The implication of the Paris Agreement is clear: to limit the rise in temperature to well below 2°C by the end of the century, carbon neutrality must be achieved by 2050. Alstom is committed to science-based CO2 emissions reduction targets in line with the Paris Agreement.

Alstom is committed to supporting carbon neutrality in transport and has adopted a “Climate and energy transition strategy” along three lines:

  • placing energy-efficient electrical rail solutions at the heart of its portfolio;

  • enabling the transition to sustainable mobility solutions;

  • decarbonising its operations.

Our eco-design strategy

Alstom’s eco-design policy consists of continuously improving the sustainability performance of its solutions by monitoring and reducing their environmental impact throughout their entire lifecycles. The priorities set in Alstom’s eco-design policy focus on : energy efficiency of rail transport systems; use of clean, recyclable, and natural materials; reduction of noise and vibrations; reduction of air emissions; and end-of-life management of products, particularly in maintenance activities.

On the production side, lifecycle assessments help to identify significant environmental aspects and improvement areas and assist in the making of technical choices. On the customer side, the environmental product declarations (EPDs) provide a detailed picture of the impact of various Alstom solutions.

Eco-design: a pathway towards sustainable mobility

Read more

Alstom’s state-of-the-art light rail vehicle (LRV), the Citadis X05, is being pioneered as a public transport solution in Sydney, Australia. Its impact on the environment will be minimised through increased energy efficiency achieved by the use of electrical braking, permanent magnet motors, LED lights, sensor-based air-conditioning and the use of water-based paints and non-hazardous materials for construction. The energy requirements have been reduced by more than 15% and each vehicle is 99% recyclable at the end of its lifespan (30 years).

A complete portfolio of sustainable solutions

In line with its commitment to facilitate a global transition to a low-carbon transport system, Alstom has pioneered several sustainable mobility solutions.

Coradia iLint

Our zero direct carbon emission, hydrogen fuel cell powered train - the Coradia iLint - is the very first of its kind. Emitting only water, it offers an alternative to diesel trains.


Mastria is a multimodal traffic orchestrator designed to meet the current and future needs of smart cities. It makes use of advanced data analytics and algorithms to coordinate all types of public transport, from rail to road (metro, train, tramway, suburban, bus). It also manages traffic incidents and provides information passengers in real-time.


Hesop, our advanced reversible power-supply substation, allows the recovery of over 99% of the available energy during braking and re-injects into the electricity network, thus reducing both CO2 emissions and costs.

Signalling solutions: enhanced capacity and efficiency

Our signalling solutions allow for lower energy costs and a reduction of consumption of up to 30%. Through newly built solutions or the upgrade of existing solutions in place, we can help ease city congestion and make collective transportation even more attractive.

Alstom Coradia Polyvalent: new green solutions

In February 2020, we have received an order for eleven battery powered regional trains for the Zweckverband Verkehrsverbund Mittelsachsen (VMS) in Germany. These were the first battery trains to be ordered from Alstom. Offering both hydrogen and battery is an important milestone for the Alstom, as it further proves our central role on the emission-free mobility market.

Trains go green: focus on battery and hydrogen

We've tailored the Coradia range to operate with all available emission-free power systems, from electric to battery-electric and hydrogen fuel cells. 

Joining the public debate and common initiatives

Our commitment to fighting climate change extends beyond the sphere of its own solutions. Alstom has teamed up with a number of leading bodies working to promote corporate involvement in overall sustainable development.

In 2008, Alstom joined the United Nations’ Global Compact organisation, designed to encourage companies to commit to a set of key values spanning human rights, labour standards, environmental protection and ethics in business practices. 

As a member of the Paris Process on Mobility and Climate (PPMC) and an active participant in the UN Climate Change Conference , Alstom is a key contributor to various international initiatives that aim to combat climate change in transport and reach the +2°C target set by the Paris Climate Agreement. Besides, the Group continues to support UNFCCC forums (United Nations Framework Convention on Climate Change) to show how its technologies support the transition towards a low carbon emissions society.

Alstom is a member of the “Sustainable Low Carbon Transport Partnership” (SLoCaT) initiative that brings together international players committed to sustainable mobility.

Alstom is a founding member of the Transport Decarbonisation Alliance, which gathers States, local authorities and industrialists eager to accelerate the transformation of the transport sector into a sector with zero net CO2 emissions by 2050.

As a member of the International Union of Public Transport (UITP), Alstom signed its Charter of Sustainable Development.

“We need partnerships […] to allow this decarbonised hydrogen to emerge. As part of a broader energy policy, we know that hydrogen can play a key role in clean energy storage.”

Promoting alternative solutions to diesel for transport

Alstom’s participation to the One Planet Summit in Paris in December 2017, outlined the company’s long-term strategy regarding transport decarbonisation, and emphasised the essential role of hydrogen in clean energy storage.

Alstom is a highly active member of the Hydrogen Council, which was launched at the World Economic Forum 2017 in Davos and aims to accelerate investment in the development and commercialization of the hydrogen and fuel cell sectors. As part of its “sustainable pathway for the global energy transition”, the Council has established that 10% of trains sold for non-electrified railways could be powered by hydrogen by 2030.

In 2017, Alstom joined the Corporate Partnership Board (CPB) of the International Transport Forum (ITF). The ITF is an intergovernmental organisation with 66 member countries that facilitates global dialogue for better transport. The CPB is the ITFs platform for engaging with the private sector and enrich global transport policy discussion with a business perspective. By joining the ITF, Alstom actively participates in policy-related projects on transport infrastructure and services and the decarbonisation of transport. 

Collaboration with research institutes

We are also teaming up with leading research organisations to share scientific knowledge and research initiatives. This is another vivid illustration of Alstom’s contribution to combating climate change and facilitating the shift to sustainable mobility.
