We are keenly aware of our responsibility and duty as a government agency to set an example, and we are committed to ensuring the well-being of our people and to preserving living ecosystems.
Our corporate social responsibility (CSR) policy covers the three social, economic and environmental pillars of sustainable development, aligned with France’s CSR roadmap and the UN Sustainable Development Goals (SDGs).
CNES is working to promote space as a tool for gaining new insights into environmental phenomena, nature conservation, efforts to combat climate change and for the sustainable use of outer space.
CNES intends to play its part in meeting the government's ecological transition commitments. Charting a future path to sustainable space with our stakeholders and ecosystem, keeping people and the planet in mind, is the greatest ambition there is for a government agency like ours.

The 3 commitments of our CSR strategy
CNES has defined 3 main CSR issues taking into account the opinion of its stakeholders.
CNES prioritizes the well-being of its employees and implements this through ongoing social dialogue between management and employee representative bodies, resulting in numerous agreements, such as those concerning teleworking or the balance between the professional and personal lives of employees.
Furthermore, as a public institution, CNES must also lead by example and promote this same dynamic within the space ecosystem. This translates into the implementation of an ambitious responsible procurement policy and the collaborative development of CSR frameworks for activities within the space ecosystem. In addition, CNES has a core responsibility to transmit knowledge and raise awareness among young people.
France has placed climate and environmental issues at the heart of national objectives championed at the highest levels of government. These objectives rely in particular on ecological planning implemented at the local level, and on the "Eco-responsible Public Services" initiative, which defines a specific trajectory for public bodies. CNES (the French National Centre for Space Studies) fulfills this duty to set an example and relies on a substantial body of laws and regulations.
The various missions of CNES contribute to understanding, measuring, and combating climate change. The data produced by space missions enable scientists and policymakers to define appropriate measures to limit the consequences of climate disruption and adapt to it. CNES is committed to implementing the space sector's decarbonization roadmap for its activities and projects.
As an ISO 14001 certified organization, CNES must identify the significant environmental aspects of its activities (resource consumption, energy, transport, etc.) in order to control its significant negative environmental impact (loss of biodiversity, air pollution, etc.). It must also optimize its beneficial environmental impacts (use of renewable energies, etc.).
To reduce the environmental footprint of its projects, activities and establishments, CNES is developing ambitious actions targeted in 9 priority areas: food, energy and low carbon strategy, buildings and infrastructure, biodiversity, waste and the circular economy, water resources, mobility, digital technology and space missions.
CNES is a public company serving the public interest. It constitutes an instrument of national and European sovereignty and strives to be exemplary in carrying out its missions. As such, in accordance with its purpose, it meets the expectations of its stakeholders and ensures that it works for the common good, particularly within the territories where it operates.
In constant contact with the scientific community, CNES works to develop knowledge and fundamental know-how within its area of competence and contributes to the development of tools, technologies and models.
CNES promotes and supports the French space ecosystem, ensures that it remains competitive and innovative at the European and international level, and ensures its resilience in the medium and long term.

Supporting the citizens of tomorrow, today
In 2025, education at CNES means: 460,000 young people made aware (including 3,275 students who visited the CSG), 30,800 young people directly involved in the educational projects implemented, 130 students who completed a 3rd-year internship for one week, spread across CNES sites.

A strengthened policy for sustainable procurement
The Procurement and External Revenue Department has decided to strengthen CNES's sustainable procurement policy. Purchases (equipment, space studies, etc.) account for approximately 80% of the greenhouse gas emissions in our annual report. CNES is working with its ecosystem (suppliers, partners) to reduce these emissions by incorporating CSR requirements into its calls for tenders.
