The Sustainable Fashion Communication Playbook (short: the Playbook) aims to provide a shared vision, principles and guidance on how to align consumer-facing communication across the global fashion industry with sustainability targets, incorporating both environmental and social factors. It shows how fashion communicators – marketers, brand managers, imagemakers, storytellers, media, influencers and beyond – can help advance towards the Paris Agreement and Sustainable Development Goals (SDGs) through: 1) countering misinformation and greenwashing, 2) reducing messages perpetuating overconsumption, 3) redirecting aspiration to more sustainable lifestyles, and 4) empowering consumers into their role as citizens to demand greater action from businesses and policymakers. It does so in the context of recognising the fashion sector as one of global importance, but one struggling to address its wide-reaching impacts, with unsustainable patterns of consumption and production contributing directly and significantly to the triple planetary crisis of climate change, nature and biodiversity loss, and pollution and waste (UNEP 2021c; UNEP 2023), as well as the interlinked issue of social injustice.
