Discover Change, Together.

We believe the solution to the planet’s biggest challenges lies in the power of collective action.



We believe the solution to the planet’s biggest challenges lies in the power of collective action.




By taking action in our own lives and inspiring the people around us, each of us contributes to a world of impact.


EcoChallenge provides tools and inspiration to turn intention into action, and gives participants a fun and social way to think about and act on proven solutions that make a difference for you, your community, and the planet. EcoChallenge has been changing the habits and lives of participants across the world since 2010. In 2016, we reimagined the EcoChallenge platform, and we’re in the process of dramatically scaling our reach — and more importantly, scaling the impact we’re having on our world.

Our seasonal global challenges are free and open to everyone. In 2018, our October EcoChallenge had 16,610 participants representing over 80 countries and 2,400 cities. You can also use the power of the EcoChallenge platform to create a Challenge for your workplace, college, or community. Your Challenge can be completely customized to meet the needs and goals of your community. You can engage any or all of our Challenge categories (energy, food, water, waste, nature, community, simplicity, transportation) and select actions from our library…or create your own categories and actions! We invite you to set up a demo to see how EcoChallenge could work for your organization, and find out more about our other programs too.


EcoChallenge is part of a suite of educational and engagement offerings by the Northwest Earth Institute, a nonprofit organization based in Portland, Oregon. For over 25 years, we’ve inspired, educated and activated individuals around community-based change. To date, we have engaged over 240,000 individuals and 4,500 organizations through solutions-focused programs. Our approachable and ready-to-use social and digital tools provide a unique framework for talking about our relationship with the world and sharing new ways to listen, live, and create positive action. These tools include a suite of Discussion Courses rooted in transformative learning and a digital platform designed to create widespread behavior change. Together, they provide the launchpad for emerging generations and sustainability leaders to experience “ah-ha” moments that lead to extraordinary environmental and social change.
