This letter was collaboratively written with dozens of aligned groups. As the weeks of action called by Extinction Rebellion were coming to an end, our groups came together to reflect on the narrative, strategies, tactics and demands of a reinvigorated climate movement in the UK. In this letter we articulate a foundational set of principles and demands that are rooted in justice and which we feel are crucial for the whole movement to consider as we continue constructing a response to the ‘climate emergency’.
