Pathways to a Circular Economy in Asia-Pacific Cities
At the same time, the diverse socioeconomic conditions across Asia-Pacific cities require pathways that reflect regional contexts while improving resource efficiency and promoting the introduction of circular business models.
Against this backdrop, this session will discuss how circular cities can be advanced in the Asia-Pacific region. Drawing on practical experiences from Asian cities and insights from diverse stakeholders, participants will explore institutional frameworks to support resource circulation, public-private collaboration, and the roles of citizens and local communities.
The session will also examine concrete actions to strengthen regionally appropriate transition models and enhance the effectiveness of the Asian Circular Cities Declaration (ACCD) framework.

Business Sector Session
Industrial Transformation and the Role of Cities toward a Circular Economy – What Companies Advancing Circular Economy Expect from Cities
Going forward, companies will be required to quantitatively demonstrate the circularity of products and materials, traceability, reuse rates. As GCP becomes a common language for businesses, local governments will increasingly need to shift from traditional waste management toward industrial policies that circulate resource value.
In this session, international organizations will present global trends in industrial policy surrounding the circular economy and explore opportunities for collaboration between companies and cities. And case studies from diverse fields such as manufacturing, construction, digital transformation, and packaging, the session will highlight what companies expect from cities.
The session will also examine expectations from companies toward cities—such as collection and recycling infrastructure, regional circulation data, data integration, public procurement, and demonstration environments—while exploring new circular city models through public–private collaboration.

Finance Session
Resource Circulation Systems and Finance in Asia-Pacific Cities
This session will provide information that contributes to enhancing the bankability of cities, including schemes for loans and technical assistance by international financial institutions, risk-sharing mechanisms, and requirements for project information.
In addition, this session will reexamine the roles and significance of intermediate treatment facilities—such as waste-to-energy plants—within resource circulation systems, from perspectives including sanitation improvement and greenhouse gas reduction.
Furthermore, by introducing case studies of urban projects, this session will clarify key points related to risk allocation, ensuring profitability, and institutional development. Through presenting pathways for effective project development via collaboration among international organizations, cities, and private companies, we aim to promote increased investment in resource circulation systems suited to Asia and the creation of concrete projects.

Public-Private Dialogue
Possibility of Aligning Municipal Policies and Business Activities to Accelerate the Circular Economy – Public Procurement, Supply Chains, and Advanced Resource Circulation
Part 1: Circular public procurement (especially in construction) and evaluation systems implemented by local governments can be key drivers in shaping markets for the circular economy. This part will share municipal policies and initiatives, particularly in the construction sector, and discuss challenges and opportunities in combination with practical examples from companies in the same field.
Part 2: One of the major challenges in advancing the circular economy is the establishment of circular supply chains. This part will present municipal policies and initiatives to support supply chain development and businesses, and explore challenges and opportunities alongside practical examples from relevant companies.
Part 3: Municipal digital transformation (DX), data development, and the advancement and optimization of resource circulation—aligned with the progress of circular business practices in the private sector—are expected to enhance urban competitiveness. This part will share local government policies and initiatives on resource circulation DX and system advancement, and discuss challenges and opportunities with insights from corporate practices in the same field.

Plastic Pollution and Local Governments
Drawing on domestic and international case studies, participants will examine policy approaches available to local governments, including measures to reduce single-use plastics, improve waste separation and collection systems, and promote reuse and refill models. The discussion will consider regulatory measures, economic incentives, and behavior change strategies.
Building on the latest developments in the Intergovernmental Negotiating Committee (INC) dialogue on plastic pollution, toward a global plastics treaty, the session will clarify key bottlenecks faced by cities, including institutional constraints, coordination with businesses, cost burdens, and limited alternatives to plastic products. The discussion will explore the role and limitations of local governments, as well as opportunities for alignment with international agreements, national policies, Extended Producer Responsibility (EPR) schemes, and the private sector.
