Our Aim

PIONEERING THE FUTURE OF CIRCULAR ECONOMY

Our Circular Gaia Symposium is a transformative annual international gathering dedicated to advancing the circular economy as a cornerstone of sustainable development. Aligned with the EU Green Deal, UN Sustainable Development Goals, the UNFCCC and the Paris Agreement, our mission is to reshape the global economic model to boost energy transition and climate resilience towards climate neutrality. We promote holistic circular solutions across sectors, including circular cities, innovation, tourism, energy transition, and the blue economy, while integrating cultural heritage and civil society into sustainability strategies.

Our focus spans the Mediterranean, Black, and Red Sea regions, uniting efforts to address production, consumption, renewable energy, ecomobility, and circular AI. By fostering circular diplomacy and championing green projects, we aim to mainstream circular principles into policies and businesses, creating a resilient, sustainable future for all.
