Ahead of the UN climate conference Cop30 in Brazil, US activist groups are gearing up to advocate for climate action, despite the Trump administration's decision not to send a delegation. The absence of federal representation comes amid a backdrop of significant environmental rollbacks and a general anti-climate stance from the administration. Activists, however, are determined to show that a large segment of the American population supports stronger climate policies. They plan to highlight successful local initiatives, such as 'polluter pay' laws in Vermont and New York, and push for ambitious international commitments to combat climate change. The conference is seen as a critical opportunity to reinforce the message that climate action is both necessary and popular, countering the narrative propagated by the current administration.
