Join our movement

Green Apple started as a single day of service, engaging over 1 million volunteers in 80 countries over the span of 8 years. Now, bring everything they learned to your school and get started greening your campus. These resources will help you identify the topic you want to address, how to get started, and how to involve students and your community.
