This policy brief, Transformative Narratives for Climate Action: Win-win strategies linking climate and sustainable development goals, discusses the key role of Transformative Narratives for catalysing climate action and elaborates some of the empirically-grounded transformative narratives produced in the GREEN-WIN project. In particular, the brief emphasises that win-win strategies that meet climate and economic goals can provide the basis for transformative narratives that are key to catalysing climate action. The brief discusses transformative narratives based on win-win strategies in the areas of rural energy poverty eradication, urban sustainability, and adaptation infrastructure. Additionally, the brief examines policies for scaling up win-win strategies like knowledge sharing, collaboration with domestic and international networks, and capacity building.
