© 2019, Springer Nature B.V. Win-win solutions (WWSs) that reconcile climate with economic goals offer a new suite of opportunities to build the necessary economic conditions for achieving a good life for all and reaching the Sustainable Development Goals. However, a systematic assessment of such solutions is still missing. Addressing this gap, a Global Dialogue on win-win solutions was implemented within the GREEN-WIN project to (1) co-develop a vision about ‘which kind of economy do we want for which kind of world?’, (2) identify exemplary WWSs in diverse domains of action and (3) evaluate the possibilities to scale win-win solutions and thus contribute to changing current core economic practices. Our assessment focuses on the potential of ‘scaling out, up and deep’ of solutions to attain a vision of a sustainable world. We find that critical factors for scaling such experiences across the globe are initiating and facilitating opportunities for sharing information and knowledge, boosting multi-stakeholder collaboration and co-creating and building transformative capacities, while ensuring financial support for niche experimentation.
