Most young adults in Europe want to be involved in action to tackle climate change and have little faith in current leaders to take significant climate action. To best communicate with young adults, build awareness and understanding of what climate justice really means, use language that connects rather than divides, and focus on ideas, inspiration and infrastructure for building action. Survey results show that almost one in 10 respondents said they would be prepared to break the law to tackle climate change, and a large majority (81%) agreed that we need a social transformation – changing our economy, how we travel, live, produce and consume – in order to tackle climate change.
