Plastic pollution is an environmental crisis and a leadership challenge. In this episode of #shifthappens, we sit down with Nanette Medved Po, founder of HOPE and Plastic Credit Exchange (PCX), to talk about what it takes to move from pledges to action. From failed treaty negotiations to grassroots innovation, Nanette shares how governments, businesses, and individuals can take real responsibility for their plastic footprint. We cover lessons from why “start and improve” beats waiting for perfection and how leaders can turn systemic problems into opportunities for impact.
