ECORETO21 is a recurring monthly challenge, allowing individuals to join at any time and complete the program at their own pace—while moving as part of a larger national community. This collective rhythm reinforces social norms and makes individual actions visible and scalable.

Since its inception, over 50,000 people in Guatemala have completed the program. The adaptability of both the content and format has made ECORETO21 a powerful tool across diverse contexts. Its simplicity, accessibility, and results-driven approach have allowed it to be integrated into classrooms, corporate initiatives, and academic programs alike. To date, more than 350 schools, 10 companies, and 2 universities have used ECORETO21 to incorporate environmental education.

Because changing behavior is the key.
