The City Playbook is an action-oriented framework intended to guide municipal officials and local actors in their efforts to develop reusable packaging models. The report includes an overview chapter on the potential and challenges for reuse systems in cities, a chapter with guidelines on how to build a reuse city, and a final chapter on practical recommendations for cities to advance reuse systems within and beyond their borders.
These recommendations are divided into: short term, suggesting what can be done now, with little investment; medium term, recommending what can be done within 1 to 2 years, with moderate investments; and long term, advising on what can be done within 2 to 5 years, with more substantial investments.

Key insights:
- To enable the transition to reuse systems, municipalities have to adopt a multistakeholder and cross-disciplinary approach, collaborating internally across divisions and agencies, as well as externally with private sector, civil society, academia and other public-sector actors.
- In collaboration with other public- and private-sector stakeholders, city authorities should put in place robust reporting, monitoring, evaluation and learning frameworks to be able to measure and optimize social, environmental and safety impacts of reuse models.
- Municipal government leaders can stimulate circularity and market innovation by building circular-procurement capacity at the municipal level, leading a market dialogue to facilitate cross-sectoral collaboration, and expanding circular procurement through cooperation across a region.
