🌐 With #UNGA underway, States must uphold the international rule of law to prevent the continuation of genocide in Gaza.

There can be no environmental justice while the universal nature of human rights faces such grave and flagrant violations.

Plastics Treaty talks are over. After 11 grueling days of delays, distractions, and gaslighting, we are leaving Geneva without a treaty. But countries stood firm against fossil-fueled interests — hope for an ambitious #PlasticsTreaty lives on.

We are entering the final stretch. An insult of a text was mostly rejected by countries yesterday (except by petro states and the chemical industry, which tells you all you need to know about it). Let’s see if we can unlock this today … stay tuned

In the final hours of #PlasticsTreaty talks, the Chair has dropped a text. "This isn’t a treaty to end plastic pollution — it’s a gift to polluters." It's completely unacceptable. So, what’s next? @melissabluesky.bsky.social‬ explains.

🔥 Crucial point at 🇺🇳#PlasticsTreaty negotiations: process' chair proposes new draft based lowest common denominator & compromising ecosystems & human health.
😡 Such a treaty would consolidate status quo, benefiting polluters.
🙅Delegates must reject this text and get back to drawing board.

Plastic is often seen as a cheap material but scientists in The Lancet argue it is expensive when including damage to health

One estimate of the health damage from just three plastic chemicals – PBDE, BPA and DEHP – in 38 countries was $1.5tn a year.
