Our Mission

We empower everyday people to #BeTheChange. 

We help people get together, make a difference, and feel better by starting and growing thriving green teams in their communities. We bring people together across the world to collaborate and create a more just and verdant world.

Our Vision

Green Team Academy is working to become the global leader in mentoring and mobilizing communities. 

Our Values

We believe that every person is an expert in their own community. With a little bit of support and guidance, they can take their ideas for improvements and make them a reality.

We see people around the world stepping up to become grassroots leaders, quickly getting environmental and community initiatives off the ground and making a positive impact.

We believe that we can transform our world by offering individuals an opportunity to transform themselves and their communities. 

We believe in making extra efforts to reach out to those who have been impacted most by environmental and economic inequities. We know that when we develop relationships with people in our communities and across the world, we all benefit.  

Our Team

Meet the team that's helping make the magic happen! As a newly hatched nonprofit, we are starting with an Interim Board of Advisors and a Community Advisory Board. We are excited to be creating an inclusive board with youth and a diverse group of people from around the world. Interested in joining our team? Apply here!

In 2020, our top 29 teams planted 43,000 trees, started 55 gardens and two urban farms, completed 84,000 voter outreach contacts, provided typhoon relief, and held clean-ups and food drives. The challenge resulted in the formation of sustainability groups in communities around the world, including Team GREAT Golden, Fountain Together, and Drawdown Alberta. 

Our goal for 2021 is to help launch 250 environmental and community initiatives and feature the top teams in our December Impact Summit. We count on community volunteers and partners to help us meet this audacious goal! Learn more.
