The Minderoo Foundation made the invisible crisis of plastic pollution impossible to ignore with The Plastic Forecast, a groundbreaking campaign linking plastic pollution to something universal which impacts us all: weather. Launched during the UN Plastic Treaty negotiations in Paris, the campaign introduced the world’s first weather forecast for plastic rainfall, using scientific data to quantify the kilograms of plastic falling from the sky—even when it doesn’t rain! Supported by digital, social, and OOH media near UNESCO talks, the Plastic Forecast web app provided real-time data and actionable tools. With 1.31B reach, 2,350 media mentions, and UN endorsement on World Environment Day, the campaign transformed abstract pollution into an urgent cultural conversation.
