Despite the Trump administration’s reluctance to participate in the UN climate summit, US civil society groups are preparing to advocate for aggressive international climate action at the upcoming conference. These groups aim to demonstrate that the current administration’s views on climate change, including its withdrawal from a key international climate treaty, do not represent the beliefs of all, or even a majority, of Americans. Among these representatives is Collin Rees, US program manager at the environmental non-profit Oil Change International, who will attend the annual UN climate conference, known as Cop30.
