Hotel Carbon Measurement To Calculate Carbon Footprint

Written byAlice Coita

The Hotel Carbon Measurement Initiative (HCMI) is a methodology and free tool developed for hotels to calculate the carbon footprint of hotel stays and meetings in their properties.

HCMI enables hotels to measure their total carbon footprint, the carbon footprint per occupied room on a daily basis, the carbon footprint per area of meeting space on an hourly basis, and renewable energy and electricity as a portion of total consumption.

Developed by the hospitality industry, HCMI aims for a consistent methodology across all hotels to measure and communicate their carbon impact, improving understanding, transparency, and accuracy industry-wide. The data from HCMI is used by hotels in the Cornell Hotel Sustainability Benchmark Index and the Hotel Footprinting benchmarking tool.

HCMI covers all on-site energy usage, including fuels, purchased electricity, and mobile fuels, as well as emissions from refrigerants and, where applicable, carbon emissions from outsourced operations like laundry services.

Launched in June 2012 by the Sustainable Hospitality Alliance and the World Travel & Tourism Council, along with 23 global hospitality companies, HCMI applies aspects of the GHG Protocol Standards. It has been tested in various hotels worldwide and updated in 2016 and 2022, incorporating feedback from users and research by Cornell University’s Center for Hospitality Research.
