T20 Task Force Circular Economy: Circular economy measures to keep plastics and their value in the economy, avoid waste and reduce marine litter: Policy Brief for the G20, The 2030 Agenda Climate & Finance Trade & Investment
AI summary Read the abstract
This T20 policy task force report proposed circular economy measures to reduce plastic pollution entering oceans, including extended producer responsibility, improved collection systems, and design standards for recyclability. It argues that current linear approaches to plastics are economically unsustainable as well as environmentally harmful.
We live in the plastic age (the “plasticene”), producing over 300 million tonnes (mt) of plastic every year globally, 5-15 mt of which flow into already polluted oceans. Plastic remains a key material in the global economy, but low rates of collection, reuse and recycling, emissions of microplastic from product wear and tear, and often insufficient disposal measures are leading to far-reaching environmental, health, social and economic impacts. The costs of inaction are unacceptably high. Globally there is a growing recognition of the need to address marine litter and rethink our approach to plastics and plastic packaging within the economy. Measures that enable a transition to a circular economy can avoid waste and reduce marine litter, and contribute to keeping plastics and their value in the economy.

Marine plastic pollution and extended producer responsibility in the G20
AI summary Read the abstract
This systematic mapping of 100 academic and policy sources analyzed how extended producer responsibility (EPR) can reduce marine plastic litter in G20 countries, which are responsible for a significant portion of global plastic production and consumption. The review recommended strengthening legislative frameworks, incentivizing plastic return markets, improving lifecycle management of plastics, and coordinating EPR strategies from global conventions to local implementation in the context of ongoing UNEA Resolution 5/14 treaty negotiations.
Circular economy measures to keep plastics and their value in the economy, avoid waste and reduce marine litter
AI summary Read the abstract
This review argues that circular economy measures — including improved collection, reuse, recycling, and design for end-of-life — are necessary to keep plastic value in the economy while reducing the estimated 5-15 million tonnes of plastic entering oceans annually. Researchers present a framework of policy and industry measures to transition away from the current linear 'make-use-dispose' model that drives marine litter accumulation.
Circular economy measures to keep plastics and their value in the economy, avoid waste and reduce marine litter
AI summary Read the abstract
This policy-oriented paper examines how circular economy measures — including improved collection, reuse, and recycling of plastics — can reduce marine litter and keep plastic materials and their economic value in the economy rather than allowing them to leak into marine environments.
Six Proposals for Future Policies towards Circular Economy and Society
AI summary Read the abstract
This G20 policy brief proposed six priorities for mainstreaming circular economy principles globally, starting with capitalizing on public concern about marine plastic pollution to drive policy momentum. The recommendations also covered extended producer responsibility, circular business models, regional ecological networks, international policy harmonization, and integrating planetary boundaries into circular economy metrics.
Tackling Marine Plastic Pollution Through Source-To-Sea Approach and Circular Economy

This paper reviews the global problem of marine plastic pollution through a source-to-sea lens and proposes circular economy principles as a path toward solutions. It discusses policy instruments, extended producer responsibility, and international cooperation needed to address marine plastic litter.
