The 2025 Colorado Economic Impact Study (CEIS) quantifies the on-airport and visitor spending economic impacts at airports throughout Colorado. Economic impacts will be estimated for each individual airport included in the study, updating the prior impacts published in 2020. The CEIS is a tool to communicate the benefits of airports, both quantitative and qualitative, and helps justify the continued public investment in Colorado’s airport system. The 2025 CEIS will also include a detailed analysis of the role of airports in supporting air cargo and economic development, the contribution of airports to Colorado’s agriculture industry, tax impacts from aviation activity, and the vast economic impact of the Denver International Airport.
