The source materials for most plastics are fossil fuels. As fossil fuel firms lose their iron grip on energy markets, experts say, they're shifting to making plastic. Recycling is a narrative that allows them to present plastic as a clean product.

The Stockholm COP added toxic pesticide chlorpyrifos and PFAS group LC-PFCAs to its global ban list. IPEN welcomed the move but warned that broad exemptions for chlorpyrifos leave children at risk. Science – not profit – must guide chemical safety.

"It's about the precedent." Delegates debated whether to allow a persistent organic pollutant elimination listing to be re-opened to accommodate the aircraft manufacturing industry.
