Our Story

The idea of GreenBuzz started in March 2010 in Zurich, when Falko Paetzold invited around 15 sustainability professionals for a casual drink – 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 drive sustainability, grow the momentum and build on the traction that GreenBuzz had been gaining since 2010. Since then, the GreenBuzz community has grown to more than 3,000 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, Amsterdam, Geneva and Bern. Currently, we are working on expanding GreenBuzz Global to establish global reach and impact.
