Real people. Real progress.
Join a global community of professionals powering the transition from linear to circular economies. CEI membership gives you the recognition, resources and connections to make a real impact.
Why become a CEI member?
Professional membership signals your commitment to excellence in circular economy practice. It tells employers, clients and peers that you meet rigorous standards of competence, experience and ethical conduct.
But membership is about more than credentials. It connects you with a worldwide network of circular thinkers and doers who share your vision of moving the world beyond waste. Together, we are empowering a circular future.

Our members span 40+ countries and work across every sector. Through regional clubs, online platforms and events, you will build relationships with practitioners tackling similar challenges. Share knowledge, collaborate on solutions and contribute to advancing circular economy practice worldwide.
