Our team

Senior manager
Anne Devieilletoile
With a degree from Sciences Po Strasbourg, Anne spent 9 years in auditing and consulting. Within KPMG France, she most notably co-piloted international framework contracts for development projects financed by international donors (UNHCR, European Commission, etc.). Shen then assisted organisations (large companies, SMEs, local authorities, government agencies...), in their search for European funding and helped to design EU projects in a variety of fields (water reuse, air quality monitoring, environmental scoring of food products, etc.).
​
Trained to use the Global Biodiversity Score (GBS) as a level 2-certified GBS assessor, Anne supports companies in their biodiversity approach within BioInt. She led the biodiversity footprint assessment of an agri-food holding company and contributed to the design of methodologies for measuring pressures and impacts for financial institutions (support for the design of their methodology for measuring the impact of their assets on biodiversity).
​
Anne is also involved in a number of projects relating to methods of measuring and accounting for the state of biodiversity and ecosystems, for example when supporting the Nature Positive Initiative on indicators of the state of ecosystems, designing a certification method for a French pilot of biodiversity credits, and preparing the Ecosystem Condition Protocol initiative.

Her orchestral clarinet playing has given her a keen sense of listening and attention to detail, enabling teams to work harmoniously.
