Ariane Thomas

As L’Oréal’s Global Tech Director for Sustainability and Trustworthy AI since 2021, Ariane leads the Group’s responsible technology strategy, focusing on achieving high performance while upholding social and environmental responsibility. She governs and directs L’Oréal Group responsible tech processes based on four strategic pillars: Sustainable Tech by Design, Tech for Sustainability, Inclusive Tech, and Trustworthy AI.

A biologist by training, Ariane spent 12 years in L’Oréal’s Luxury division, primarily addressing supply chain challenges. Then, drawn to complex projects, her two-decade journey in sustainability includes developing the Group’s responsible sourcing program (2005), establishing and directing the Global Environment department (2008), and leading Strategic Development Operations (2015-2021). Her broad expertise spans responsible technology, ethics, supply chain management, environmental and social issues, resource efficiency, and the circular economy.

Ariane’s influence extends beyond L’Oréal. She actively contributes to business associations (Medef, AFEP, France Industrie) and serves on the boards of Hub France Intelligence Artificielle, iMPACT AI, and Positive AI. Ariane embraces the L’Oréal Group’s motto, inspired by François Dalle: “Seize what’s beginning”.
