Annual Conference

Each year, students and educators from around the world come together at the CEI Annual Conference to share their sustainability projects, insights, and experiences. Hosted in a different country every year, the conference has been running for 39 consecutive years and has built a global community committed to environmental action and education.

This year marks the 40th CEI Conference, taking place in Türkiye, and we warmly invite you to join us either in person or online for this milestone celebration of collaboration and sustainability.
