Barbara Chastellain


With a DAS (Diploma of Advanced Studies) in sustainable management, I support companies in a global CSR (Corporate Social Responsibility) approach or for specific needs in sustainability through 3 axes: strategy, credibility and training. My initial studies in business administration supplemented by an experience of more than 15 years in various fields (project management, finance, SAP, business analyst), give me a 360° vision of the company, and enables to define a sustainability strategy in line with its mission and values.

I also support companies in the Valais region in the Swiss Triple Impact (STI) program around the Agenda 2030 and the SDGs.

As a facilitator of the Climate Fresk, I organise workshops related to climate change for the general public, companies, schools (from 9 years old) and public institutions.

Whether in a private or professional context, I believe that sustainability should not be synonymous with discouragement or moralising, quite the contrary.
Convinced of the magic of collective intelligence, we created the cooperative society Yétik to unite our skills and our good mood.
