Three days, two capitals, one Mediterranean: the Circular Gaia Symposium 2026
Long before anyone spoke of “sustainability” Greece and Egypt were already in conversation. In the 5th century BC, Herodotus travelled along the Nile and wrote with wonder about Egypt’s knowledge and customs. In 331 BC, Alexander the Great founded Alexandria, which under the Ptolemies became the intellectual capital of the ancient world, home to the great Library, to Euclid and to Eratosthenes. Centuries later, a thriving Greek
community helped shape modern Alexandria and Cairo, the city of the poet Cavafy.
This October, that conversation continues, and for the first time, the Circular Gaia Symposium travels with it. After two days in Athens, the symposium crosses the Mediterranean to Cairo for a third day. Our message is simple: the two shores of the Mediterranean must think, plan and build a circular future together.
One sea, one future
The Mediterranean is warming faster than almost anywhere else on Earth. Heatwaves, water scarcity, pressure on coastlines and the growing burden of waste are felt as strongly in Athens as they are in Cairo. These challenges do not stop at borders, and neither can the solutions.
Circularity (keeping materials in use, designing out waste and regenerating natural resources) is one of the most powerful tools we have. It works best when knowledge, investment and ideas flow freely between north and south. The Mediterranean has always been a bridge, not a barrier. Circular Gaia 2026 is our invitation to use it that way again.
Egypt: Africa’s leading voice for sustainable change
Egypt stands today as one of Africa’s leading forces, and its progress on sustainability deserves real recognition.
In 2022, Egypt hosted COP27 in Sharm el-Sheikh, placing Africa’s climate priorities at the centre of the global agenda. It was the first country in the Middle East and North Africa to issue a sovereign green bond, showing that green finance has a home in the region. The Benban Solar Park near Aswan is among the largest solar installations on the planet, while wind farms along the Gulf of Suez and ambitious green hydrogen plans in the Suez Canal Economic Zone are positioning Egypt as a clean energy hub for Africa and beyond. Guided by its Vision 2030 and a modernised national waste framework, Egypt is proving that growth and sustainability can move forward together.
Greece and Egypt: a partnership built on trust
Few relationships in the Mediterranean are as close as the one between Greece and Egypt. Rooted in shared history and a modern friendship that grows stronger every year, this partnership is now turning into concrete cooperation for a greener future.
The planned GREGY electricity interconnector, linking Egypt and Greece through a subsea cable, promises to carry clean energy from North Africa to Europe and strengthen energy security on both shores. The long-standing trilateral cooperation between Greece, Cyprus and Egypt has built a trusted framework for joint work on energy, the environment, tourism and investment. Circularity is the natural next chapter: sharing expertise on waste and water, building joint value chains for recycled materials, and investing together in the green industries of tomorrow.
Athens and Cairo at the heart of Mediterranean environmental cooperation
Nowhere is the bond between Athens and Cairo clearer than in the Barcelona Convention, the region’s landmark treaty for the protection of the marine environment and coastal areas of the Mediterranean. Its Secretariat, the UN Environment Programme’s Mediterranean Action Plan (UNEP/MAP), has its home in Athens. And in December 2025, Egypt hosted the Convention’s 24th Conference of the Parties (COP24) in Cairo, bringing together some 600
participants from 21 Mediterranean countries, the European Union, UN agencies and civil society to celebrate 50 years of the Mediterranean Action Plan and chart the region’s course for the next decade under the banner of a sustainable blue economy.
Since COP24, Egypt holds the Presidency of the Barcelona Convention and its Bureau for 2026–2027, placing it at the helm of Mediterranean environmental cooperation. With the Secretariat in Athens and the Presidency in Cairo, the two capitals are already working hand in hand to protect the sea we share. Circular Gaia 2026 builds on that partnership, and it is no coincidence that UNEP/MAP supports our Cairo day and that its Blue Economy panel carries forward the spirit of COP24.
Days 1 and 2: Athens
On 9 October at the historic Athens Conservatoire and on 10 October at EPLO’s premises in Plaka, government ministers, European Commissioners, EU officials, leading academics and industry pioneers will come together across 14 thematic panels, from the EU Circular Economy Act and green finance to circular islands, critical raw materials, farm-to-fork agroeconomy and circular diplomacy.
A highlight of the Athens programme captures the spirit of this article perfectly: in the Circular Cities panel, Dr. Kostas Bakoyannis, former Mayor of Athens, will share the stage with Prof. Khalid El Adli, former Governor of Giza and former Dean at Cairo University, bringing the experience of both capitals into one conversation.
Day 3: Cairo
On 11 October, the symposium moves to the Cairo House Cultural Center, co-organised with Egypt’s Ministry of Local Development and Environment and supported by UNEP/MAP. The day opens with an address by H.E. Manal Awad, Minister of Local Development and Environment, followed by panels on the Blue Economy, the future of the sea that unites us, and on Women in Sustainability, celebrating the women leading the green transition across the region.
For the first time, Circular Gaia will not only talk about bridging the Mediterranean. It will do it.
Why you should be there
Whether you are a policymaker, an entrepreneur, a researcher, a student or simply someone who cares about the future of our region, Circular Gaia 2026 is your chance to meet the decision-makers shaping Mediterranean climate and resource policy, discover solutions already working on both shores, and build lasting connections between Europe, Africa and the Middle East.
Two shores, one conversation. Join us.
Greece and Egypt once helped shape the way the world thinks. Together, they can shape the
way the world lives sustainably.
