What People Are Saying About Vert de Gris

I've had the pleasure of working with Delphine for 14 years now. Together, we have accomplished notable milestones such as building Danone's carbon accounting system, integrated reporting, and addressing the complexities of SDG reporting.

Recently we have even tackled the CSRD and double materiality challenges!

Delphine has consistently been a driving force behind our innovative sustainability accounting projects at Danone.

Her expertise and support have been instrumental in advancing our ambitious initiatives to ensure that Danone remains at the forefront of sustainability measurement.

- Laura Palmeiro,
Sustainable Finance Director,
We at Fermes d'Avenir were really happy that Delphine helped us to develop and execute a pilot case about triple capital accounting applied to agro-ecological farms.

Not only did she and her team produce quality material, but they were also able to train our teams on field about new concepts and new tools.
Many thanks!

Former Director of Ecological Transition, Groupe SOS

I had the opportunity to work on different projects with Delphine, but our main subject matter was always related to the global performance of organizations, and the importance of changing the practices of control and verification of non-financial information.
Delphine is a recognized expert on these subjects.

She provided me with key technical knowledge, but also opened me up to a whole network of influential personalities, from regulators to academics and scientists.

Beyond her scientific knowledge, she was also skilled at adapting to our needs and being patient, flexible and educational... great assets when you want to change the rules of the game on these issues!
