Bringing more people into the climate struggle starts with transforming movement culture and opening diverse paths to entry. This article presents findings from a study of the Australian climate movement. One of the biggest themes heard from groups was the challenges they face in recruiting and retaining staff and volunteers with the skills, experience and capacities needed for climate justice work. First and foremost, we need to attend to the reasons why people experience barriers in stepping into climate work — including volunteering — by creating excellent cultures that motivate diverse and skilled people to join and stay in the movement for the long term. Second, to improve our culture, we need to open the doors as wide as possible, by creating accessible pathways into the movement for more people and, especially, for folks from more diverse backgrounds. This article gives specific ways to do each of these.
