About the Caristeo team

Frédéric Giuli, founder

Caristeo was founded by Frédéric Giuli in 2019. After a 17-year career at Accenture, a major player in international consulting, Frédéric was trained in Climate issues by Al Gore within the Climate Reality Project program.

In 2018, Frédéric decided to dedicate his energy and his consulting expertise to the climate emergency. He creates Caristeo dedicated to raising awareness and transforming companies and organizations.

He is also a founding member in 2018 of an NGO, La Fresque du Climat (, of which he is now treasurer, Blue Belt and Member of the Board, in order to broaden awareness of climate issues to as many people as possible.

Clara Crenn, climate consultant

Passionate about environmental issues since her degree in Sciences Po Bordeaux, Clara first specialized in renewable energies by completing her curriculum at Mines de Paris and then by working for several years at Akuo Energy as a renewable energy project developer.

Since she crossed the path of the Climate Fresk, her interest in climate education and transition has developed and she joined Caristeo to contribute to Climate Collage facilitations, large-scale workshop deployments, carbon footprints and decarbonisation strategies.

The Caristeo collective

The members of the Caristeo Collective are selected on the basis of their professionalism, their listening skills, their level of expertise as well as their total adherence to Caristeo’s values, among which we find scientific rigor, pragmatism and ambition to act in the face of the climate emergency.
