Hotel Carbon Measurement Initiative (HCMI)

  • Published on December 12, 2022
Hotel Carbon Measurement Initiative (HCMI) is developed to enable hotels to report in a consistent way, in particular to corporate customers. It can be used for scopes 1,2 and 3.
For Scope 3 - only emissions from outsourced laundry are included.
Used by over 30,000 hotels globally, HCMI data can be used by hotels participating in the Cornell Hotel Sustainability Benchmark Index (CHSB) – the hotel industry’s largest annual benchmarking of energy, water and carbon use.
It is also the methodology used by the Hotel Footprinting benchmarking tool.


This resource has been reviewed as part of the Technical Brief on Measuring Tourism Greenhouse Gas Emissions: An overview of current measurement methodologies and tools and recommendations for ways forward within the framework of the Glasgow Declaration on Climate Action in Tourism.
