The Zero Waste Festival, held from June 4 to 7 at Istanbul Atatürk Airport, placed public participation at the centre of one of Europe’s major environmental gatherings. Organized under the auspices of H.E. Emine Erdoğan, Chair of the UN High-Level Advisory Board on Zero Waste, by the Zero Waste Foundation, in cooperation with the Ministry of Energy and Natural Resources, the festival formed part of Istanbul Zero Waste Week and welcomed more than 1 million visitors.
Across four days, the event brought together sustainability, culture, art, technology, energy efficiency and practical zero waste applications. Its wider relevance lay not only in its scale, but in the way it presented zero waste as a shared experience shaped by daily habits, family activities, creative work and community participation.
Turning zero waste into public culture
Visitors moved through workshops, exhibitions, interactive areas and awareness programmes designed for different age groups. Children and families took part in practical learning spaces, environmental games and creative activities, while wider audiences encountered recycling and upcycling practices, sustainability education, art works and technology-led experiences.
This approach gave the festival a distinct role in the broader sustainability conversation. Rather than focusing only on official commitments or technical frameworks, it showed how environmental awareness can become part of public culture when citizens are invited to participate directly. In this setting, zero waste became tangible, accessible and connected to choices made at home, in cities and across communities.
“The scale of public participation in İstanbul shows that zero waste is no longer an abstract environmental concept. It is becoming a shared culture shaped by families, children, young people, artists, innovators and citizens who want to be part of the solution. As the world looks toward COP31, this festival offers a clear example of how climate action can be strengthened not only through policy and diplomacy, but also through direct public engagement,” said Samed Ağırbaş, President of the Zero Waste Foundation and COP31 High-Level Climate Champion.
From participation to climate action
His remarks underline the festival’s broader significance on the road to COP31. As climate discussions increasingly focus on implementation, public engagement is becoming essential to turning climate ambition into behavioural change. The Istanbul gathering suggested that zero waste can gain practical force when it is carried beyond government policy, international negotiations and institutional commitments into everyday life.
The festival’s programming reflected that idea. Art installations and transformation-focused workshops explored how materials can gain new value when waste is prevented and resources are used responsibly. Exhibitions and cultural areas translated sustainability into visual and participatory formats, while technology and energy efficiency spaces offered visitors a closer look at innovation, resource use and practical systems that can support more sustainable living.
For children and families, the festival created a direct form of learning. Hands-on activities, environmental awareness programmes and creative workshops allowed younger visitors to engage with zero waste through participation rather than instruction alone. For adults, the event offered a broader view of how circular economy practices, conscious consumption and energy efficiency can be connected to daily routines.
A two-level sustainability platform
The relationship between the Zero Waste Forum and the Zero Waste Festival gave Istanbul Zero Waste Week a two-level structure. The Forum opened a space for policy, diplomacy and strategic discussions on zero waste, circularity and climate action. The festival carried the same agenda into public life, translating a high-level sustainability conversation into experiences that citizens could see, test and discuss.
That connection is important as the world looks toward COP31. International climate processes often depend on negotiations, targets and institutional coordination, yet their success also requires social acceptance and behavioural change. The Zero Waste Festival offered a public-facing example of how climate action can be strengthened when citizens are not treated only as observers, but as participants.
By attracting more than 1 million visitors, the festival positioned itself among Europe’s major environmental events and underlined growing public interest in sustainability. More importantly, it showed that zero waste can become a shared culture when policy objectives are supported by education, creativity, technology and public involvement.
As governments prepare for COP31, Istanbul’s Zero Waste Festival demonstrated that lasting climate action depends not only on international agreements, but also on the everyday choices of citizens. By turning sustainability into a shared public experience, the festival illustrated how implementation begins long before delegates enter the negotiating room.
