Nature has always been a source of inspiration and innovation for our Maison. Protecting, conserving and restoring Nature is essential to ensure the quality and sustainability of the raw materials derived from it.

In Brittany, across Europe, and in remote regions worldwide, we partner with local stakeholders to establish ethical sourcing programmes for the natural ingredients used in our products.

Concretely, this translates into:

Signing framework agreements that include support for implementing environmentally friendly agricultural practices or installing improved processing equipment, such as stills.

Financing Biodiversity Action Plans as part of UEBT verification processes.

Providing direct support to producers in implementing their socio-environmental action plans, for example by supplying first aid kits or firefighting equipment to our partner beekeepers.

An in-depth knowledge of our partners

The actions carried out are based on a deep understanding of our suppliers, with whom we have built enduring relationships.

Our fragrance development, sustainable development, and purchasing teams regularly meet them in the field.

Guerlain expands its exclusive partnership in Grasse with Domaine Le Mas des Sources dedicated to perfume plantes.

Guerlain maintains a partnership with the Gastaldi family, owners of Domaine Le Mas des Sources in Grasse, based on shared values and a love of perfume flowers.


Their 4-hectare (10-acre) organic farm ensures the continuity of Grasse’s traditional expertise by producing roses, tuberoses, and verbena.


Beehives were installed on the estate in 2023, and an independent audit was conducted by UEBT in 2024, allowing the best practices in place to be approved, including organic and traditional growing practices, drip irrigation and a traceability system to ensure the quality of the flowers harvested.

A structured certification process

To structure and certify its strategic supply chains, Guerlain relies on two recognized standards: UEBT and Fair for Life, with the goal of reaching 70 supply chains audited under UEBT Ethically/Responsibly Sourced or Fair for Life by the end of 2026.
