Service Description

Benchmark your hotel’s sustainability performance

The Cornell Hotel Sustainability Benchmarking Index (CHSB) is an industry-led global data initiative, started in 2013 to enable any hotel to calculate its carbon footprint and benchmark its energy, water and carbon emissions at low cost, drawing from a dataset of over 27,000 hotels around the world. Participants in the CHSB index include major hotel brands, operators and owners, representing a total of 1,072 geographies (83 countries, 84 regions, 709 market areas, 185 climate zones).

CHSB 2024 Participating Companies

“Focusing on a hotel’s environmental performance has the triple benefit of reducing its impact, improving operational profitability and asset values. The CHSB Index is the leading tool for benchmarking hotel environmental performance. At the property level, we can benchmark the performance of our hotels with their local competitors to understand their positioning, evaluate opportunities for improve, as well as drive some friendly competition.”

Tom Mallet, Global Director of Decarbonization and Sustainable Performance, Accor

“We are proud to have been one of the founding participants in the annual CHSB index since it began in 2013. We are delighted to see the significant growth of the dataset over the past 10 years to provide valuable data to hoteliers, customers, and the wider travel industry. CHSB data allows our hotels to benchmark performance against comparable peers and gives us a bird’s-eye view across the portfolio.”

Marie Fukudome, Associate Vice President, Sustainability and ESG Reporting, Hyatt

“The Peninsula Hotels has been a part of CHSB for 9 consecutive years, since the launch of the benchmark. Throughout the years, we were able to leverage the CHSB findings to understand our sustainability performance in relation to our 5 star and luxury hospitality peers, and ensure our progress is in line with the industry’s expectations and trends. We are glad to have seen more luxury hotels joining CHSB and the expansion of the index to include more relevant indicators for meaningful benchmarking in years to come.”

Joshua Wong, Head of Corporate Responsibility and Sustainability, The Peninsula Hotels

See who is using CHSB data

CHSB is used widely as the source data set for benchmarking and footprinting.

CHSB also supplies real data to the Greenview Hotel Footprinting Tool to estimate the carbon footprint of a single or for multiple hotel room nights and meeting spaces across the world. This information can be used to calculate a company’s business travel hotel stay carbon footprint for Scope 3 reporting and offsetting, or provide information for clients on whose behalf you are booking or offsetting travel.

Access the Validity Testing Fences for Energy and Water Data

Validity tests are performed on Energy and Water data provided by participants to detect possible data issues and identify outliers.

By referring to this Fences Table, properties can review their environmental performance and determine if they fall within range. The fences table shows the lower and upper limit thresholds which is based on the previous CHSB data set.
