Purpose: This study aims to describe the different elements included in campus sustainability plans (CSPs) in colleges and universities across the USA. Design/methodology/approach: It examines the contents and specific areas of emphasis of 155 CSPs using a document analysis approach. It determines the types and characteristics of the institutions that have adopted these plans. Findings: The first CSP was written in 2000 and at least 155 plans have been written as of 2021. Only a small percentage of US institutions of higher education have a written CSP, and among those, large public institutions had the most. The quality of these plans varied greatly, indicating a lack of standardization. Engagement was the most discussed topic, and some aspect of campus operations was mentioned in every plan. Social equity was the least prevalent topic. Research limitations/implications: This research focusing on US colleges and universities may have overlooked plans that have other titles. Nevertheless, it is a fairly comprehensive analysis of campus sustainability planning efforts to date in the USA. Practical implications: This study has important practical implications for institutions that aspire to craft their first sustainability plan or those that wish to revise their existing plan in a comprehensive manner. Originality/value: This study builds on a conceptual foundation of plan review by several other authors but presents a more robust and comprehensive method of application specific to CSPs. It fills a wide gap in the literature on the quality and content of CSPs by examining over five times more plans than were analyzed in an older study and addresses some of the research questions from previous articles.
