The Future of Circular Architecture and Society

~Exploring the Potential of Green Buildings in a Circular Economy~

As the world faces urgent global challenges – ranging from climate change and biodiversity loss to environmental pollution, water scarcity, resource overconsumption, and deepening economic and social inequalities – the circular economy emerges as a vital key to unlocking sustainable solutions, where the lifecycle of building material contributes significantly to embodied carbon emissions.

GBJ Symposium 2025 will serve as a platform to collectively explore the principles and practices of the circular economy, to envision a future where circularity drives the co-creation of a resilient society, and directly to address the urgent need to reduce both operational and embodied carbon.

Presentation and Panel Discussion

Designing the Circular Future: Architecture, Society, and the Next Frontier.

Realizing a circular economy requires a fundamental shift away from the traditional linear model of “take, make, dispose.” It calls for a transition to a new system that reduces waste and pollution, circulates resources, and regenerates nature—bringing benefits to people, the economy, and the environment.

This program consists of two parts. In Part 1, leading panelists will present concrete initiatives from their respective fields, exploring circularity through diverse perspectives such as conceptual frameworks, architecture, and societal systems. In Part 2, companies that have begun engaging with circular economy practices will join the discussion. Together with insights from green building, they will explore multifaceted approaches that span across scales. Through the intersection of knowledge across disciplines, the program aims to uncover new possibilities for co-creating a circular society and economy that connects to the future of our built environment.
