How does a global plastics treaty get negotiated? Researcher Tara Olsen joins host Clark Marchese to explain the process, actors, and competing interests behind the United Nations effort to regulate plastic pollution. Using the road to the Busan negotiations as context, they discuss international environmental law, national sovereignty, industry and civil-society influence, and the difference between signing and ratifying a treaty. This evergreen UN plastic treaty guide focuses on how global environmental agreements are built and what determines whether they can deliver meaningful accountability.

Anti-plastic norms spread when health enters the story. Global health policy researcher Leah Shipton explains how local plastic bag bans developed into an international movement, with examples from early policy adopters including Bangladesh and Kenya. She and host Clark Marchese discuss norm entrepreneurs, industry opposition, media attention, policy learning, and the power of framing plastic pollution as a health issue. The episode traces the path from grassroots anti-plastic movements to global plastics governance and the negotiations for a United Nations treaty.
