Products and Services for Sustainability

Offering customers innovative and eco-responsible functions and services that will enable them to reduce their own greenhouse gas emissions.

In line with the second objective of its Strategy for a Low-Carbon Future, Thales works to offer its customers innovative and eco-responsible functions and services that will enable them to reduce their own greenhouse gas emissions.

How do we do it?

  • By developing smart traffic management solutions (encompassing rail, road, sea and air) that will reduce emissions.
  • By optimising the energy efficiency of the digital world through the development of solutions that are “designed for energy efficiency” in the areas of digital data science, algorithms and artificial intelligence.


Reconciling security, growth and environmental protection.

Everywhere that human beings travel, Thales technologies and innovations (such as lighter aircraft, optimised flight paths, energy saving trains and metros, and smoother urban traffic flows) help make people safer and more comfortable, while improving the environmental performance of equipment. 

Thales’s solutions for air and ground transportation operators are designed to optimise operating efficiency while limiting environmental impact (by optimising flight times, securing flight paths, reducing fossil fuel consumption, and helping to reduce emissions of pollutants such as carbon, sulphur and nitrogen oxides). 

Air Transport

Thales has more than 30 years’ experience of developing flight management and air traffic management functionalities designed to improve performance and reduce impact (in terms of noise, fuel consumption and emissions) during all phases of a flight.

Integrating energy transition issues into product design

To deliver genuine sustainability, the incorporation of environmental factors into the product development process has to  create value for Thales and its customers, in terms of improved operating conditions, reduced total ownership costs, and optimised end-of life management. This aspect is addressed specifically via Thales’s product policy, and via the eco-design initiative, which is aimed at reconciling value proposition with reduced environmental impact

Two priority areas for improvement:

  • Use of sustainable resources in product design and manufacturing, with a particular focus on hazardous substances, quantities of materials, and recyclability.
  • Reduction of energy consumption and COemissions during product use.

Reducing our digital carbon footprint

Reconciling the boom in digital technologies with environmental imperatives.

Thales is taking a proactive approach to the issue of “digital sobriety”, and is committed to developing a long-term strategy. The Group is making a binding commitment to take action now to ensure a lower-carbon digital environment.

  • In the defence sector, Thales is developing remote services and secure connectivity solutions which, in addition to reducing energy footprint, help to improve the safety of soldiers in-theatre as well as boosting mission autonomy and effectiveness. 
  • The Group is supporting revolutionary research projects that include a complete rethink of machine architecture with the aim of delivering a tenfold increase in data storage and processing capacity, while considerably reducing energy needs. This work involves the use of artificial nano-neurones that emulate the functioning of the human brain.
  • The mission-critical applications that Thales is working on need to be backed up by technology systems that are understandable and can be trusted. TrUE AI is the new development framework for Thales projects in artificial intelligence. Thales is committed to deploying a digital strategy and developing a low-energy digital world. The Group's teams are exploring new avenues to reduce the energy consumption of data-driven artificial intelligence as much as possible, particularly within the framework of TrUE AI. Thales is looking for alternatives to deep learning, which is criticised for its opacity and high consumption of data and energy. 
  • Edge computing is an optimisation method used in cloud computing that allows data to be processed at the edge of the network in which it is generated. This method reduces the bandwidth required for communication between sensors and data processing centres, by performing analysis and knowledge-gathering tasks as close as possible to the source of the data.

Eco-responsible AI: a major opportunity in terms of environmental protection

AI and data-driven systems have both positive and negative environmental impacts. While AI helps to reduce energy consumption (through optimisation of air and ground transport, smart city applications, etc.), it also consumes large quantities of energy during production and use, just like any other electronic system. Thales researchers are working on a four-pronged approach to make artificial intelligence more eco-responsible:

  • Reducing the impact of AI during the production phase by applying eco-design principles to product development, and developing software-defined equipment to mitigate obsolescence issues.
  • Improving AI algorithms by factoring energy consumption into the design of neural network architectures, and, whenever possible, prioritising the development of knowledge-based symbolic or hybrid AI, which is much more energy-efficient.
  • Favouring data quality over quantity, and adopting distributed architectures that retain certain centralised functions when absolutely necessary, in order to optimise bandwidth usage, and therefore energy consumption, without sacrificing performance.
  • Improving electronics and implementation by developing electronic circuits that consume very little energy, and leveraging applications of spintronics, the electronics of tomorrow, for extensively connected analogue systems.

Sustainable procurement

The Procurement Department plays a key role in meeting the challenges of climate change. Thales is committed to gaining a better understanding of the carbon footprint of those suppliers whose products or services generate the highest emission levels.

Our Sustainable Procurement policy, focused on value creation, innovation, business partnerships and operational excellence, aims to give Thales a lasting competitive advantage at global level.

The policy has six key priorities:

  • Holding suppliers accountable with respect to applicable laws and regulations.
  • Establishing good-quality relations based on mutual loyalty.
  • Sharing expertise to boost innovation.
  • Involving suppliers alongside Thales in the fight against climate change.
  • Providing specific support to local SMEs with opportunities for international development.
  • Expanding the use of third-sector and social outreach players.

In 2021, a “Low Carbon” questionnaire was sent out to more than 100 suppliers in the purchasing categories identified as having the highest greenhouse gas emissions. The questionnaire is used to measure suppliers’ maturity based on communication of their own carbon footprint and their reduction strategy. Initial responses from the suppliers surveyed show a growing commitment to this issue.

Also in 2021, the Procurement Department launched pilot tender processes for air travel, short and long-term car rentals and packaging that included weighted selection criteria relating to reductions in the carbon footprint of the goods and services purchased, and to respect for the environment. When entering into the relevant purchasing contracts, suppliers will be required to commit to quantified and milestone based emissions reduction targets.

In 2021, Thales received the Supplier relations and Sustainable procurement certification, which rewards companies for maintaining balanced and sustainable relationships with their suppliers. Official certification is a welcome reminder of the crucial role that procurement plays in Thales's corporate social responsibility policy.

Responsible buyer label
" This certification is particularly important because it is fully aligned with ISO 20400, the international sustainable procurement standard that integrates social responsibility into the procurement function. "
