Plastic pellets are not harmless cargo. 🐣 Decades of research show they are persistent, widely dispersed, ingested by wildlife, and capable of carrying hazardous chemicals across oceans. 🌍🌊 In our new perspective, we call on the IMO to recognize the risks and strengthen global regulation. ⚓

Following the first round of voting by secret ballot, no candidate received a majority of votes to be the next Chair of the Plastic Pollution INC. Unless the two candidates with the most votes can reach agreement for one to step aside, the INC will proceed with a second round of voting. #plastics

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. 1/13 www.theguardian.com/environment/...

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. Read more here: ipen.org/news/toxic-p...

At the top, a banner in red with white text reads: “Read: Toxic Pesticide Chlorpyrifos and Large Chemical Group Set for Global Bans,” with the IPEN logo and tagline “for a toxics-free future” on the left. The setting and message convey the context of a high-level global policy meeting addressing toxic chemical regulations.

IPEN and @acat-akaction.bsky.social strongly oppose a proposal to reopen the 2023 decision to ban UV-328 – a toxic chemical already phased out in many regions – and warn that granting new exemptions would set a dangerous precedent. Read our joint submission here: ipen.org/documents/re...

Looked into some of the misleading statistics behind recycling percentages of plastics. EU data talks about 41% recycling rates, currently, for plastics. But from the underlying data it seems like it's actually closer to 6-9% 🤔 ipen.org/sites/defaul...
