Culture and Climate Change: Assemblies is rethinking citizen participation in climate policy. As a collective of climate-citizen-researchers (including academics from the fields of communication, politics, architecture and art practice; climate-focused organisations; and diverse and minoritised local communities within climate discourse), we are exploring the potential for speculative climate storytelling and novel forms of documentation within participatory democratic processes, in order to ask questions about how these might benefit and impact follow-on action post-climate assembly. Through participatory creative activities we are testing how collective narrative scenarios and climate future imaginaries can help us more deeply interrogate policy recommendations and how we might broaden citizen participation in relation to climate policy.
