When city leaders and business leaders collaborate, it can lead to a virtuous circle through which initial resilience actions by cities lead to actions by businesses that lead to further action by cities. Since 2013, the Center for Climate and Energy Solutions (C2ES) and Bank of America have partnered to better understand how companies are preparing for climate change. This latest work reflects our findings that businesses need government to take action too. This guide is an important first step that provides city leaders and planners concrete recommendations they can take to invite and promote public-private collaboration on city climate resilience planning in their communities. Cities that follow the steps in this guide can build a collaborative climate resilience planning process to ensure the city’s climate resilience plan benefits from the insights of the private sector and works best for the community overall.
