Green Ambassador (GA) Certificate

The “Take-Make-Waste” economy is at a tipping point. We need to counter irresponsible practices and a culture of convenience that is depleting resources faster than they are replenished and endangering species through human created emissions and pollution.

Are you passionate about environmental sustainability? Do you want to understand the drivers and impacts and make a meaningful impact in your community? Sustainability is not a destination, but reflection on mitigation actions and adaptation strategies. We need ambassadors that drive net zero thinking and stewardship to interact with the planet responsibly.

Each module covers challenges, solutions, regulations, standards, technology innovation, success stories, actions, blogs, resources and exercises. Resources have recommendations to help in your journey to sustainability - e.g. farm to table restaurants, refilleries, reusable grocery/ produce bags, eco dry cleaning, recycling, composting.

  • Join the workshops where 12 modules will be taught by industry experts.

  • Optionally, join a litter cleanup, prior to each workshop, to protect our parks and wildlife and keep our waterways clean.

  • Compete for annual awards based on the number of events and certificates completed and receive service hours.

  • The program is open to ages 11+; children under the age of 11 must be accompanied by an adult. 

  • While in-person is preferred, if you miss a class, you can watch the recording online.

  • Completion of the quizzes will yield an academic certificate.
