GREENMAN SPEAKS ESG
Matthias Gelber is widely regarded as one of the world's best ESG, sustainability and decarbonization speaker, transforming what is often perceived as a complex and dry subject into an engaging, impactful and inspirational experience for audiences.
“Let's make a living from healing the planet, rather than from destroying it.”
We can make a difference, simply by choosing a pro-environmental way of living and working. We can choose to be an agent of change, one small action at a time.
I’m Matthias Gelber (aka the Green Man), and I’m on a powerful mission to make ESG not just a corporate checkbox, but a transformative force for change.
My mission goes beyond just delivering talks; I’m driven by the belief that ESG and sustainability can be a catalyst for innovation, culture change, and long-term positive impact on both people and the planet.
