The European Circular Economy Stakeholder Platform (ECESP) - a joint initiative by the European Commission and the European Economic and Social Committee - is hosting the second edition of the Circular Economy Days at World Expo 2025.
From 22 to 24 September, the ECESP will organise a series of events designed to foster dialogue and collaboration among European and Japanese practitioners, policymakers, businesses, and innovators in the circular economy. The NEB will feature in two of these events.
Fashion footprint: Unraveling the environmental impact of textiles and acting against it
Monday, 22 September 2025, 10:30 - 12:00 (JST) - Polish Pavilion
The textile sector is a vital part of our lives. The sector is not only vital to economies and cultures, it is also a significant contributor to environmental challenges such as waste, pollution and resource depletion. This event will be an opportunity for various actors (manufacturers, policymakers, designers, sustainability advocates, etc.) to share insights about forward thinking solutions that will help reimagine the future of textiles and build a more circular sector.

New European Bauhaus & Green Cities
Monday, 22 September 2025, 13:30 - 15:00 (JST) - EU Pavilion
Cities are at the forefront of the green transition, acting as living laboratories where environmental policies are tested and deliver tangible benefits for citizens. This session will explore what makes a city truly green—from circular economy approaches and nature-based solutions to climate-adapted urban spaces.
Framed around the NEB, it will showcase inspiring examples of sustainable architecture, innovative materials, and urban strategies that harmonize with nature, highlighting key areas from Commissioner Roswall’s portfolio, including water management, circular economy, and resilience to extreme weather. Contributions from European Green Capital winners and Japanese city pioneers will illustrate how local initiatives and national policies drive concrete benefits: better quality of life, efficient resource use, stronger communities, and supportive business environments.
The second part of the session will focus on the NEB, with architects from Europe and Japan joining Commissioner Roswall to discuss how sustainable architecture shapes greener cities and daily life. The discussion will also explore the impact of small-scale projects on broader urban transformation and potential convergence between European and Japanese visions for sustainable design.
