Why Sustainable Leadership matters now more than ever

And it is exactly these daily habits at work and what you can change to act more climate friendly that this course is about. Learn what resources are used in an average office or home office on a daily basis & how everyday work processes such as printing, commuting to work, waste disposal or the choice of lunch affect our climate, and how you can contribute to creating an environmentally friendly workplace - a so-called green office.

What privious participants say about the Masterclass

To be honest, it was quite shocking for me to hear in clear words that we are the first generation to feel the climate change and at the same time being the last generation that can still influence it on that. But raising awareness of the importance and what I personally can contribute was a real benefit from this training. (Birgit Brater; Head of Supply Chain)

A very comprehensive training about facts and measures for a sustainable behavior, and inspiring speakers who motivate us to lead in the transformation of our business models as well as our working lives. (Romana Aumer; Head of Customer 360°, Business Unit Enterprise)

In the spirit of Ann Marie Bonneaus quote “ We don´t need a handful of people doing carbon reduction perfectly – we need millions of people doing it imperfectly”, we as leaders have a special role - we are multipliers and should take our teams along on the ESG journey. The Masterclass offers nuggets of knowledge, many impulses, exchange & reflection on one's own actions - a perfect foundation to become a Sustainable Leader. (Britta Schindler; Head of People & Change)
