This guide aims to support civil society representatives communicating with the general public about finance industry reform with knowledge on how to effectively talk about the industry and make the case for regulation that works for people and the planet. It is the culmination of a collaborative project involving the Transforming Finance Network, New Economy Organisers Network, and Public First. It builds on a public perceptions research briefing published in November 2022 and a series of focus groups held in 2022/23.
