Being a network of 3000+ professionals, GreenBuzz Berlin is determined to support committed individuals to succeed together on all the different sustainability goals.

In the past 5 years, GreenBuzz Berlin has organized over 60 networking events and brought together about 5000 people on these events. Recently we received numerous requests for recommendations, help and input on various topics in sustainability. We consider us facilitators rather than sustainability experts, but realize that we have become a go to address for these topics.

While we cannot provide the expertise in all the areas we receive requests, we can provide some, but would much rather reach out to all of you as experts in the various topics.

Making this world more sustainable is a team effort that requires benevolent collaboration. This is what we want to facilitate more in the future and the GreenBuzz CONNECT Program is our next step to to just that.




How To Join

Our first workshop will be held on 21st May. Together with CO-Happening, we’ll address your specific challenges & needs from other sustainability professionals. Please note that the workshop is limited to 10 participants.

So to ensure your spot, please fill out the form below and let us know what your challenge is. Or if you think you have skills that you would like to offer to support others in their sustainability missions, please also fill out the form.

You don’t have to choose, naturally, everybody can be in both roles!
