Summary of Regional Plastics Outlook for Southeast and East Asia

Core Content

This document, Regional Plastics Outlook for Southeast and East Asia, provides an in-depth analysis of plastic pollution trends, current policies, and future projections for the ASEAN Plus Three (APT) region, which includes 10 ASEAN countries and three East Asian countries: China, Japan, and Korea. It aims to support policy design and implementation in the region and offers a long-term perspective on plastics use, waste, and environmental impacts up to 2050.

Main Insights

• Plastics are pervasive and beneficial but their lifecycle leads to environmental pollution, climate change, and biodiversity loss.
• Plastic pollution is a major issue in Southeast and East Asia, driven by rapid growth in plastic use and inadequate waste management systems.
• Plastic leakage is significant, especially in coastal areas, due to factors like high rainfall and poor waste infrastructure.
• Current trends are unsustainable, with plastics use and waste generation projected to increase substantially without stronger policies.
• Without intervention, by 2050, plastic waste generation would more than double, and leakage would rise by over 66%.
• High Stringency policies can lead to a 28% reduction in plastics use, 23% reduction in plastic waste, and over 95% reduction in plastic leakage in the APT region.
• Environmental and economic benefits of stringent policies are evident, though costs are unevenly distributed across countries.
• Policy coordination is essential to address transboundary plastic pollution and align with global goals.

Key Findings

• Plastics use is highly heterogeneous across APT countries, with some nations having much higher per capita use and intensity than others.
• Packaging is the largest plastics application, with a significant share of plastic waste originating from this sector.
• Waste management systems are inadequate in most APT countries, leading to high levels of mismanaged waste.
• Plastic leakage to the environment is expected to increase, with rivers being the primary pathway for plastics to reach the ocean.
• Lower middle-income countries (LMICs) in the APT region are particularly vulnerable to plastic leakage due to weak waste management systems.
• Ambitious policies are needed to reduce plastic use, improve recycling, and close leakage pathways.
• Economic growth drives plastics use, but the region is projected to shift towards more service-oriented economies.
• Extended Producer Responsibility (EPR) and eco-design measures are key to reducing plastic waste and leakage.

Policy Scenarios

• Baseline Scenario: Projections under current policies show continued growth in plastics use and waste, with significant environmental impacts.
• High Stringency Scenario: This scenario involves comprehensive and stringent policies that can significantly reduce plastics use, waste, and leakage, leading to environmental and economic benefits.
• Differentiated Stringency Scenario: While costlier, this scenario does not fully eliminate plastic leakage.
• Global High Stringency Scenario: While beneficial globally, the APT region can act decisively to end regional plastic leakage through high stringency policies.

Policy Roadmap

• The report outlines a policy roadmap to virtually eliminate plastic pollution in the APT region.
• It highlights the need for a coherent policy mix, including reduction, recycling, and eco-design measures.
• Implementation considerations include strengthening local financing, coordination, and data systems.
• Public engagement and multi-level governance are essential for effective policy implementation.
• Examples of successful policies include Japan's Johkasou system for wastewater treatment and Indonesia's waste banks that incentivize rural recycling.

Environmental and Economic Impacts

• Plastic leakage is expected to triple by 2050 under the Baseline scenario, but can be eliminated with High Stringency policies.
• GHG emissions from the plastic lifecycle are projected to double by 2050, highlighting the need for climate-friendly policies.
• Economic impacts of High Stringency policies are modest in terms of GDP but vary across countries.
• Recycling rates are expected to increase significantly in all APT countries under High Stringency policies.
• Secondary plastics use grows rapidly in the High Stringency scenario, promoting circularity in the plastic lifecycle.

Methodology and Data

• The report uses state-of-the-art environment-economy models to project plastic flows, waste generation, and environmental impacts.
• Data collection involves a comprehensive review of national and regional policies, as well as economic and environmental trends.
• Key data sources include national statistics, environmental reports, and international databases.

Conclusion

The APT region is a critical player in the global fight against plastic pollution. Without ambitious and coordinated policies, the environmental and economic consequences will be severe. The High Stringency scenario offers a viable path to a cleaner and more sustainable future, emphasizing the importance of policy innovation, enforcement, and international cooperation.
