of expertise

sustainable fashion & luxury

Fashion and luxury companies are under strong scrutiny and expected to be sustainable, engaged and ethical. However the culture of secrecy, their traditions of quality and the complexity of the sourcing of their raw material makes it challenging.

Our in-depth knowledge of hard luxury, based on significant work experience in the field, allows us to understand and support the full scope of the necessary transformation and to guide our clients.

We also run a podcast on “Luxury for good.”

future of work under climate change

What should you do when workforce stops applying for jobs in companies that have no sustainability ambition? What if they refuse to board a plane because it will impact their ecological footprint? How will you respond when they request to work from home during a heatwave? At Ethiwork, we work on these topics with various think tanks and are able to offer customized and clever answers to organizational and engagement problems both present and coming.

tech in/for good

Technology, as a major transformational tool, can have both positive and negative impact on organizations and on the world at large. At Ethiwork, we believe in supporting our clients create successful business models while mitigating possible negative effects of tech and setting the basis for positive impact.

Education is key for change, not only for young generations, but for every professional who wants to learn more and transform to its environment. Which is why we strongly believe in impact education and commit ourselves by giving classes (Essec MBA, Celsa) and trainings in companies.
