The Delfingen Group joins forces with the Solar Impulse Foundation to strengthen its environmental commitment

ANTEUIL, 3 February - The Delfingen Group is taking a new step forward in implementing its environmental commitments with the announcement of a strategic partnership with the prestigious Solar Impulse Foundation, led by explorer and visionary Bertrand Piccard.

This alliance is the result of a deep convergence of values with those of the Group's management family and aims to give a new dimension to the Group's commitment to sustainable development.

The collaboration has two main objectives:

• Create greater resonance: Harness the reputation and network of the Solar Impulse Foundation to raise awareness of the Delfingen Group's commitment and actions in the field, particularly through its Foundation.
• Partner with Solutions: Integrate and support the "Efficient Solutions" selected by Bertrand Piccard's team. These economically viable and ecologically protective solutions will enable Delfingen to optimise the environmental impact of its own initiatives, particularly those relating to access to decent housing, education and environmental projects.

This partnership is a logical follow-up to the Plastic Odyssey initiative in 2021.
