Our Story

The idea of GreenBuzz started in Zurich, in March 2010 when Falko Paetzold invited around 15 sustainability professionals for a casual drink as he was looking to meet and learn from others working on sustainability topics in different industries. GreenBuzz was a success from day one. In 2013, an independent non-profit association was founded to expand on the momentum and traction GreenBuzz was gaining ever since 2010.

Since then the GreenBuzz community grew to more than 1,500 Buzzers only in Zurich. In late 2014, GreenBuzz Global was founded to address the demand from other cities and new local chapters were founded in Berlin, Manila… and more to come.
