The Cornell Hotel Sustainability Benchmarking Index (CHSB) is an industry-led global data collection and benchmarking initiative, with data on energy, water and carbon emissions from over 20,000 hotels around the world. Participants in the CHSB index include major hotel brands, operators and owners, representing all regions of the world.

The public data set is published by Cornell’s School of Hospitality Research free of charge and contains average hotel performance for different types of hotels in different geographies. Hotels which participate directly in the index receive a confidential, bespoke benchmarking report showing how they are performing against their competitive set.
CHSB data is used by governments, corporate customers, travel management companies and numerous other organizations to determine benchmarks and estimates for energy and water usage, and carbon footprints.
