Our Hotel Footprinting Tool (HFT) directly addresses an emerging industry need of calculating Scope 3 Business Travel emissions. Business travel makes up a big part of corporate carbon footprints – hotel stays, flights and meetings all contribute to your Scope 3 value chain emissions.
As investors, clients, and regulators demand climate accountability, companies need credible data to measure and manage the impact of business travel. Gathering data from individual hotels can be difficult and time-consuming.
The HFT bridges these gaps by providing reliable, market-level benchmarks derived from the Cornell Hotel Sustainability Benchmarking (CHSB) index, powered by thousands of hotels worldwide.
Our Solution
Available since 2017, the Hotel Footprinting Tool helps you calculate the carbon footprint of hotel stays and meeting spaces worldwide — entirely free of charge. The dataset is updated annually and offers comprehensive coverage at city, state/province, and country levels, with coefficients available for all countries. It provides actual carbon footprint coefficients for most geographies, with gaps filled using transparent extrapolation from adjacent data points.
Powered by the CHSB Index — the world’s largest hotel sustainability database with default market-level benchmarks.
Aligned with the Hotel Carbon Measurement Initiative (HCMI) — the industry-accepted methodology for calculating hotel emissions.
Recognized by governments and reporting bodies including the UK and New Zealand governments’ Scope 3 guidance.
