Manja Hoffner
Environmental educator, communicator and founder. I help people and organizations live, learn and talk about sustainability — turning complex topics into clear, honest stories that move people, on and off camera. By day I lead communications and media for Dr. Eckart von Hirschhausen's environmental-health foundation, Gesunde Erde – Gesunde Menschen; the rest of the time I run the Green Living Academy: teaching, hosting tours and making green living click.
Sustainability, told in a way that sticks

Harvard-certified educator. Courses, workshops and talks that swap eco-overwhelm and perfectionism for confident, everyday action.

Productions I've made & led
Films from the "Genug, gesund, global gerecht?" series I produced and edited for the Gesunde Erde – Gesunde Menschen foundation — sustainability, food and climate justice, in conversation with people making it real.

Watch on LinkedIn →From advertising psychology to environmental education
My background is in business and advertising psychology — I learned exactly how attention and behaviour get shaped. Travelling through Asia and Australia turned the climate and waste crisis from an abstract worry into something I'd seen with my own eyes, and I decided to put those communication skills to better use.
A chance meeting with a monk named Kong San in Cambodia set it in motion — it started a friendship that's since helped build seven clean-water wells, and gave me the push to start something of my own. Back in Berlin I studied hard, got certified by Harvard, founded the Green Tours, and built the Green Living Academy to make sustainable living practical, honest and genuinely doable.
Today I bring those two worlds together: rigorous environmental knowledge and the craft of communication that actually moves people — individuals and organizations alike.
How I work
I won't pretend to know everything about sustainability — but I know a great deal, and I'm relentlessly practical about getting people and teams from A to B with humour, clarity and zero judgement. No shame, no greenwashing, no perfectionism: just honest options, real impact, and changes that fit a life or a brand.
One thing I always want to pass on:
Environmentalism is not White — and never has been.
The founders and biggest activists of the movement to heal our planet are Black, Indigenous and People of Colour — I'm grateful to learn from them and to pass on their knowledge.
